1 Introduction

Traumatic brain injury (TBI) is a major cause of deathand disability [1] At least 10 million severe TBIs result indeath or hospitalization annually worldwide [2] Approx-imately 17 million Americans sustain a TBI each yearleading to over 14 million emergency department visits275 000 hospital admissions and 50 000 deaths that con-tribute to one-third of all injury-related deaths [3] In theEuropean Union alone an estimated 15 million hospitaladmissions and 57000 deaths annually attribute to TBI[4] In China TBI-related mortality remains a high levelranging from 1299 to 1706 per population of 100 000

persons [5]Thus TBI has afforded huge social and economicburden

TBI is a diverse group of sterile injuries induced byprimary and secondary mechanisms that give rise to celldeath inflammation and neurologic dysfunction in patientsof all demographics [6 7]The primary injury is caused by themechanical stress or shear force on tissues with no therapeu-tic agents [8] The secondary injury includes a wide varietyof processes like activation of inflammatory and immuneresponse [9 10] calciumoverload [11] glutamate toxicity [12]and mitochondrial dysfunction [13] among others Currentguidelines for the management of the secondary injury areprimarily supportive including the emphasis on surveillance

(ie intracranial pressure) and the preventive measures toreduce morbidity and mortality [14] Despite the fact thatdetailed medicines contain free-radical scavengers antago-nists of N-methyl-D-aspartate and calcium channel blockers[15] the results of the controlled clinical trials of these drugsare disappointing [16] Neuroscientists and doctors tend tosearch for potential novel drugs from traditional Chinesemedicine (TCM) library to treat TBI [17]

TCM is a comprehensive medicinal system that has beenused in clinical practice for thousands of years and playsan important role in the health maintenance for people allover the world [18 19] The validated curative effects of TCMmake it a feasible alternative therapeutic agent for diseasetreatment Xuefu Zhuyu decoction (XFZYD) a representa-tive TCM formula was first recorded in Correction of Errorsin Medical Works by Qing-ren Wang XFZYD consists of11 crude herbs Persicae Semen (Tao ren) Carthami Flos(Hong hua) Radix Paeoniae Rubra (Chi shao) ChuanxiongRhizoma (Chuan xiong) Achyranthis Bidentatae Radix (Niuxi) Angelicae Sinensis Radix (Dang gui) Rehmannia glutinosaLibosch (Sheng di huang) Platycodon Grandiforus (Jie geng)Aurantii Fructus (zhi qiao) Radix Bupleuri (chai hu) andlicorice (Gan cao)Themain chemicals from XFZYD includeflavonoids organic acids terpenoids and steroidal saponins[20ndash22] The formula has been proven reliable and effectivefor curing various diseases including unstable angina pectoris[23 24] coronary artery disease [25] thromboembolic stroke[26] ischemic stroke [27] and TBI The therapeutic agent ofXFZYD is to promote blood circulation and remove bloodstasis according to the TCM theory Several randomizedcontrolled clinical trials and animal experiments have showeddefinite therapeutic effects of XFZYD for the treatment ofTBI [28ndash31] Recent researches demonstrate that XFZYDprovides neuroprotection via anti-inflammatory pathway andcognitive improvement through synaptic regulation [32 33]However merely these evidences to explain the multipletherapeutic mechanisms of TCM for TBI treatment areunavailable Because the effects of TCM are always contro-versial in terms of their abstract theory unclear basis com-plex interactions between various ingredients and complexinteractive biological systems [25] it is essential to developan advanced technique to deeply uncover the synthesizedpharmacological effects of XFZYD in the treatment of TBI

With the development of TCM modernization networkpharmacology has become a novel method to elucidate themulti-druggable targets effects of TCM [34] TCM networkpharmacology first proposed by Shao Li [35] makes itfeasible to understand the effective constituents and targetsof the herbs from TCM formula This analytical methodintegrates bioinformatics systems biology and polypharma-cology and further utilizes network analysis to imply themultiple actions of drugs across multiple scales ranging frommolecularcellular to tissueorganism levels [36 37] Coin-ciding with the holistic and systemic characteristics of TCMnetwork pharmacology is expected to bridge the gap betweenTCM and modern medicine [25] Previous researches haveclarified the scientific basis and systematic features of herbalmedicine to treat diseases through network pharmacologysuch asQing-Luo-Yin andMa-HuangDecoction etc [38 39]

In the present work we explored the pharmacologicalmechanisms of XFZYD acting on TBI via a network pharma-cology approach Network analyses and molecular dockingmethod were used to reveal candidate drug targets relatedto TBI Target analysis suggested that XFZYD regulatedseveral key biological processes of TBI development suchas apoptosis inflammation blood coagulation and axongenesis These processes contributed to the clarifying of themolecular mechanisms of XFZYD for TBI treatment Thiswill help to improve the effectiveness and specificity of TCMclinical usage (Figure 1 depicts a flowchart of the entireresearch procedure)

2 Methods

21 Database Construction The chemical ingredients of11 herbs in XFZYD were screened from Traditional Chi-nese Medicine Systems Pharmacology database (TCMSPhttplspnwueducntcmspphp) [40] As a chemically ori-ented herbal encyclopedia TCMSP can provide comprehen-sive information about herb ingredients including chemicalstructural data oral bioavailability drug targets and theirrelationships with diseases as well as the biological or physio-logical consequences of drug actions involving drug-likenessintestinal epithelial permeability and aqueous solubility [40]The structures of these compoundswere saved asmol2 formatfor further analysis Discovery studio 25 was employed tooptimize these molecules with a Merck molecular force field(MMFF) All detailed information about these ingredients isprovided in Table S1

22 Pharmacokinetic Prediction Due to the disadvantagesof biological experiments as being time-consuming and ofhigh cost identification of ADME (absorption distributionmetabolism and excretion) properties by in silico toolshas now become a necessary paradigm in pharmaceuticalresearch In this study 2 ADME-related models includingthe evaluation of oral bioavailability (OB) and drug-likeness(DL) were employed to identify the potential bioactivecompounds of XFZYD

Oral bioavailability (OB) one of the most importantpharmacokinetic parameters represents the speed of a drugof becoming available to the body and the eventuallyabsorbed extent of the oral dose [41] which is particularly sig-nificant in drug discovery of TCM formost oral Chinese herbformulas Poor OB is indeed the main reason responsible forthe unsuccessful development of compounds into therapeuticdrugs in drug screening cascades Here a reliable in silicomodel OBioavail 11 [42] which integrates the metabolism(P450 3A4) and transport (P-glycoprotein) information wasemployed to calculate the OB values of herbal ingredientsIn this study OBge30 (a suggested criterion by TCMSPdatabase) was regarded as one threshold for screening pos-sible candidate drugs presently while 2 compounds withOB le 30 were also taken into consideration due to theirtherapeutic effects according to literatures such as amygdalinand hydroxysafflor yellow A [43 44]

Drug-likeness (DL) is a qualitative profile used in drugdesign to evaluate whether a compound is chemically suitable

where X represents the molecular descriptors of herb com-pounds and Y is the average molecular properties of all com-pounds in Drugbank database (httpwwwdrugbankca)Compounds with DL ge018 (average value for Drugbank)were selected as bioactive compounds in XFZYD

In summary compounds with OB ge30 and DLge018were selected for subsequent research and others wereexcluded The criteria used here were mainly for (1) extract-ing information from the herbs as much as possible with theleast number of components and (2) explaining the obtainedmodel by the reported pharmacological data

23 Target Prediction To obtain the molecular targets ofthese active ingredients an in-house developedmodel SysDTbased on Random Forest (RF) and Support Vector Machine(SVM) methods [47] was proposed which efficiently inte-grated large-scale information on chemistry genomics andpharmacology This approach shows impressive performanceof prediction for drug-target interactions with a concordanceof 8283 a sensitivity of 8133 and a specificity of 9362

respectively [40] UniProtKB (httpwwwuniprotorg) wasemployed to obtain the standard name of the predicted targetproteins

24 TBI-Specific Protein Collecting The known therapeutictarget proteins of TBI were screened fromTherapeutic TargetDatabase (TTD available httpbiddnusedusggroupcjttd)TTD is a publicly accessible database which provides com-prehensive information about the known therapeutic proteinand nucleic acid targets described in the literature thetargeted disease conditions the pathway information and thecorresponding drugsligands directed at each of these targets[48] We also searched for Online Mendelian Inheritancein Man database (OMIM available httpomimorg) toget proteins related to TBI OMIM catalogues all knowndiseases with a genetic component and then possibly linksthem to the relevant genes in the human genome andprovides references for further research and tools for genomicanalysis of a catalogued gene [49] Then the proteinsacquired from both databases were used as hub proteinsand submitted to Human protein Reference Database [50](HPRD available httpwwwhprdorg) and STRING [51](httpsstring-dborg) to generate the proteins interactingwith these hub proteins HPRD is a database containingcurated proteomic information pertaining to human pro-teins The human protein-protein interaction (PPI) data onHPRD (Release 9) consists of 39240 interactions among 9617genesThe STRINGdatabase provides both experimental andpredicted interaction information providing a probabilisticassociation confidence score

25 Molecule Docking The LibDock algorithm based on theCHARMm Force Field in Discovery Studio (DS) 25 wasused in this study to evaluate the potential molecular bindingmode between bioactive compounds and putative targetsThecrystal structure of the target proteins of XFZYD for treatingTBI was downloaded from the RCSB Protein Data Bank(wwwrcsborg) The 3D chemical structures of bioactivecompounds were downloaded from PubMed Compounddatabase or TCMSP database and subjected to minimize theenergy by using molecular mechanics-2 (MM2) force fieldThe protein preparation protocol was used before dockingsuch as inserting missing atoms in incomplete residuesremoving water and protonating titratable residues The lig-and preparation protocol was employed before docking suchas removing duplicates enumerating isomers and generating3D conformations The protein-ligand docking active sitewas defined by the location of the original ligand All otherdocking and consequent scoring parameters were kept attheir default settings The compound was considered to be apotentially active ingredient if the LibDock score was higherthan the original ligand

26 Network Construction and Analysis Network construc-tion was performed as follows

(1) The herbs candidate compounds and candidate tar-gets of XFZYD were used to construct an herb-candidate compound-candidate target (HB-cC-cT)network

(2) The PPI data obtained above was used to establish theTBI-specific protein interaction network

(3) Herbs potential compounds and putative targetsfrom XFZYD for treating TBI were used to builda herb-potential compounds-potential targets (HB-pC-pT) network

(4) Potential targets and the biology process they partici-pate in were used to construct the pT-F network

(5) Compounds and targets through molecule dockingvalidating were used to build a compound-target (C-T) network

All networks were generated and analyzed by Cytoscape 340[52] an open source of bioinformatic package for biologicalnetwork analysis and visualization Two topological param-eters including degree and betweenness were calculated forthe obtained networks which disclose the significance ofa node

27 Gene Ontology (GO) and Pathway Enrichment Analy-sis The functional enrichment tool DAVID [53] (DAVIDhttpsdavidncifcrfgov) ver 68) was used to calculateboth the KEGG pathway and GO biological processes (BP)enrichment

28 Statistical Analysis All data were expressed as mean plusmnstandard deviation (SD) The molecule descriptors data wereanalyzed by one-way ANOVA The criterion for statisticalsignificance was p lt 005 Statistical analyses were conductedusing the SPSS 240

3 Results

TCM an experience-based medicine has been widely usedfor thousands of years It has accumulated abundant clinicalexperience forming a comprehensive and unique medicalsystem [35] The complexity of the phytochemical compo-nents makes it extremely difficult to illustrate the actionmechanisms of XFZYD from a molecule or system levelAs a chief mean of treating diseases clinically generallyTCM doctors prescribe formula based on the principle ofldquoJun-Chen-Zuo-Shirdquo ldquoJunrdquo (monarch) treats the main causeor primary symptoms of the disease ldquoChenrdquo (minister)enhances the actions of ldquoJunrdquo or treats the accompanyingsymptoms ldquoZuordquo (adjuvant) not only reduces or eliminatesthe possible toxic effects of the Jun or Chen but also treatsthe accompanying symptoms ldquoShirdquo (guide) helps to deliveror guide the other herbs to the target organs [18] Accordingto the unique feature of TCM ourwork tried to perform ldquoJun-Chen-Zuo-Shirdquo based system study to clarify the multiplemechanisms of XFZYD in the treatment of TBI

31 Herbal Ingredient Comparison and Target Predictionof XFZYD We obtained 162 components originated fromXFZYD Of these compounds 160 chemicals that were inaccord with standard requirements were searched from theTCMSP database The other 2 components amygdalin andhydroxysafflor yellow A were taken into consideration fortheir obvious pharmacological action as well The detailedinformation of these compounds is showed in Table S1Persicae Semen (Tao ren) and Carthami Flos (Hong hua)the Jun (monarch) herbs of XFZYD contained 36 bioactivecomponents which accounted for 22 of the 162 chemicalsRadix Paeoniae Rubra (Chi shao) Chuanxiong Rhizoma(Chuan xiong) andAchyranthis Bidentatae Radix (Niu xi) theChen (minister) herbs contained 31 bioactive componentswhich accounted for 19 of the 162 chemicals AngelicaeSinensis Radix (Dang gui) Rehmannia glutinosa Libosch(Sheng di huang) Platycodon Grandiforus (Jie geng) AurantiiFructus (zhi ke) Radix Bupleuri (chai hu) and licorice (Gancao) the Zuo-Shi (adjuvant and guide) herbs of XFZYDcontained 109 bioactive components which accounted for67 of the 162 chemicals Ingredients from these herbswere compared based on the 6 important drug-associateddescriptors including molecular weight (MW) number ofhydrogen-bond donors (nHdon) number of hydrogen-bondacceptors (nHacc) partition coefficient between octanol andwater (AlogP) oral bioavailability (OB) and drug-likeness(DL)The distributions of the 6 descriptors of the ingredientsfrom the three groups are shown in Table 1 and Figure 2 Wefoundno significant differences in the values ofMW(p=016)nHdon (p=032) nHacc (p=061) and AlogP (p=082) amongthe 3 groups However the average OB value of compoundsfrom the march herbs is 5559plusmn2391 which was significantlydifferent from the Chen herbs (OB=4564plusmn1327 P=0004)and the Zuo-Shi herbs (OB=4877plusmn1505 P=0021) Thefollowing 2 groups had no significant difference in OBvalue (P=0272) As for DL the Chen herbs revealed thehighest DL index (053plusmn023) which displayed significantdifference from the Zuo-Shi herbs (044plusmn019 p=0012) while

33 HB-cC-cT Network Construction and Analysis We nextestablished aHB-cC-cT network through network analysis toilluminate the relationship among the herbs candidate com-pounds and candidate targets (Figure 3(c)) This networkconsisted of 485 nodes (11 herbs 162 candidate compoundsand 285 candidate targets) and 2585 edges A herb (triangle)and cC (square) are connected if the compound is containedin this herb and the edges between cC and cT represent theinteraction The size of nodes is proportional to the valueof degree The larger size of the node means more phar-macologically important Two centrality indicators degreeand betweenness identify the important nodes within thenetwork Different centralities reflect different importanceof nodes in a network from different angles Interestingly

both of the two types of centrality indicators uniformlyconfirmed themost important 10 candidate compounds fromXFZYD and the top 10 targets anchored by XFZYD (Tables2 and 3) Figure 3(c) demonstrated that licorice possessedthe largest degree (88) compared with other herbs originatedfrom XFZYD This implicated that it contained the mostbioactive compounds (88) including quercetin (Mol 148degree=153) kaempferol (Mol 108 degree=65) 7-Methoxy-2-methyl isoflavone (Mol 33 degree=44) formononetin (Mol63 degree=39) naringenin (Mol 133 degree=39) isorham-netin (Mol 105 degree=38) medicarpin (Mol 131 degree=35)and licochalcone a (Mol 113 degree=33) followed byPersicae Semen (degree=19) Carthami Flos (degree=18)Achyranthis Bidentatae Radix (degree=17) Radix PaeoniaeRubra (degree=14) Radix Bupleuri (degree=12) ChuanxiongRhizoma (degree=6) Aurantii Fructus (degree=4) Platy-codon Grandiforus (degree=4) Rehmannia glutinosa Libosch(degree=3) andAngelicae Sinensis Radix (degree=2) PersicaeSemen (degree=19) and Carthami Flos (degree=18) the Junherbs from XFZYD possessed 29 specific compounds and5 unique target proteins including ALB CTNNB1 MMP10LYZ andNFKB1 Twenty-three Chen-specific potential com-pounds targeted 10 specific proteins including CD14 LBPNR3C1 BBC3 TEP1 PRKCD FN1 PDE10A GSTA1 andGSTA2 The Zuo-Shi herbs possessed the largest number ofspecific compounds (101) and 48 unique proteins such asHTR3A ADRA1D PYGM OLR1 CHRM5 RXRB STAT3MAPK10 OPRD1 and MAPK3 There were 189 proteinsanchored by the Jun Chen and Zuo-Shi drugs

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

2 Evidence-Based Complementary and Alternative Medicine

(ie intracranial pressure) and the preventive measures toreduce morbidity and mortality [14] Despite the fact thatdetailed medicines contain free-radical scavengers antago-nists of N-methyl-D-aspartate and calcium channel blockers[15] the results of the controlled clinical trials of these drugsare disappointing [16] Neuroscientists and doctors tend tosearch for potential novel drugs from traditional Chinesemedicine (TCM) library to treat TBI [17]

TCM is a comprehensive medicinal system that has beenused in clinical practice for thousands of years and playsan important role in the health maintenance for people allover the world [18 19] The validated curative effects of TCMmake it a feasible alternative therapeutic agent for diseasetreatment Xuefu Zhuyu decoction (XFZYD) a representa-tive TCM formula was first recorded in Correction of Errorsin Medical Works by Qing-ren Wang XFZYD consists of11 crude herbs Persicae Semen (Tao ren) Carthami Flos(Hong hua) Radix Paeoniae Rubra (Chi shao) ChuanxiongRhizoma (Chuan xiong) Achyranthis Bidentatae Radix (Niuxi) Angelicae Sinensis Radix (Dang gui) Rehmannia glutinosaLibosch (Sheng di huang) Platycodon Grandiforus (Jie geng)Aurantii Fructus (zhi qiao) Radix Bupleuri (chai hu) andlicorice (Gan cao)Themain chemicals from XFZYD includeflavonoids organic acids terpenoids and steroidal saponins[20ndash22] The formula has been proven reliable and effectivefor curing various diseases including unstable angina pectoris[23 24] coronary artery disease [25] thromboembolic stroke[26] ischemic stroke [27] and TBI The therapeutic agent ofXFZYD is to promote blood circulation and remove bloodstasis according to the TCM theory Several randomizedcontrolled clinical trials and animal experiments have showeddefinite therapeutic effects of XFZYD for the treatment ofTBI [28ndash31] Recent researches demonstrate that XFZYDprovides neuroprotection via anti-inflammatory pathway andcognitive improvement through synaptic regulation [32 33]However merely these evidences to explain the multipletherapeutic mechanisms of TCM for TBI treatment areunavailable Because the effects of TCM are always contro-versial in terms of their abstract theory unclear basis com-plex interactions between various ingredients and complexinteractive biological systems [25] it is essential to developan advanced technique to deeply uncover the synthesizedpharmacological effects of XFZYD in the treatment of TBI

With the development of TCM modernization networkpharmacology has become a novel method to elucidate themulti-druggable targets effects of TCM [34] TCM networkpharmacology first proposed by Shao Li [35] makes itfeasible to understand the effective constituents and targetsof the herbs from TCM formula This analytical methodintegrates bioinformatics systems biology and polypharma-cology and further utilizes network analysis to imply themultiple actions of drugs across multiple scales ranging frommolecularcellular to tissueorganism levels [36 37] Coin-ciding with the holistic and systemic characteristics of TCMnetwork pharmacology is expected to bridge the gap betweenTCM and modern medicine [25] Previous researches haveclarified the scientific basis and systematic features of herbalmedicine to treat diseases through network pharmacologysuch asQing-Luo-Yin andMa-HuangDecoction etc [38 39]

In the present work we explored the pharmacologicalmechanisms of XFZYD acting on TBI via a network pharma-cology approach Network analyses and molecular dockingmethod were used to reveal candidate drug targets relatedto TBI Target analysis suggested that XFZYD regulatedseveral key biological processes of TBI development suchas apoptosis inflammation blood coagulation and axongenesis These processes contributed to the clarifying of themolecular mechanisms of XFZYD for TBI treatment Thiswill help to improve the effectiveness and specificity of TCMclinical usage (Figure 1 depicts a flowchart of the entireresearch procedure)

2 Methods

21 Database Construction The chemical ingredients of11 herbs in XFZYD were screened from Traditional Chi-nese Medicine Systems Pharmacology database (TCMSPhttplspnwueducntcmspphp) [40] As a chemically ori-ented herbal encyclopedia TCMSP can provide comprehen-sive information about herb ingredients including chemicalstructural data oral bioavailability drug targets and theirrelationships with diseases as well as the biological or physio-logical consequences of drug actions involving drug-likenessintestinal epithelial permeability and aqueous solubility [40]The structures of these compoundswere saved asmol2 formatfor further analysis Discovery studio 25 was employed tooptimize these molecules with a Merck molecular force field(MMFF) All detailed information about these ingredients isprovided in Table S1

22 Pharmacokinetic Prediction Due to the disadvantagesof biological experiments as being time-consuming and ofhigh cost identification of ADME (absorption distributionmetabolism and excretion) properties by in silico toolshas now become a necessary paradigm in pharmaceuticalresearch In this study 2 ADME-related models includingthe evaluation of oral bioavailability (OB) and drug-likeness(DL) were employed to identify the potential bioactivecompounds of XFZYD

Oral bioavailability (OB) one of the most importantpharmacokinetic parameters represents the speed of a drugof becoming available to the body and the eventuallyabsorbed extent of the oral dose [41] which is particularly sig-nificant in drug discovery of TCM formost oral Chinese herbformulas Poor OB is indeed the main reason responsible forthe unsuccessful development of compounds into therapeuticdrugs in drug screening cascades Here a reliable in silicomodel OBioavail 11 [42] which integrates the metabolism(P450 3A4) and transport (P-glycoprotein) information wasemployed to calculate the OB values of herbal ingredientsIn this study OBge30 (a suggested criterion by TCMSPdatabase) was regarded as one threshold for screening pos-sible candidate drugs presently while 2 compounds withOB le 30 were also taken into consideration due to theirtherapeutic effects according to literatures such as amygdalinand hydroxysafflor yellow A [43 44]

Drug-likeness (DL) is a qualitative profile used in drugdesign to evaluate whether a compound is chemically suitable

for drug and how drug-like a molecule is with respect toparameters affecting its pharmacodynamic and pharmacoki-netic profiles which ultimately impacts its ADME properties[45] In this study the drug-likeness (DL) index (see (1))using the Tanimoto coefficient [46] was computed for eachcompound in XFZYD

1198832 + 1198842 minus 119883 sdot 119884(1)

where X represents the molecular descriptors of herb com-pounds and Y is the average molecular properties of all com-pounds in Drugbank database (httpwwwdrugbankca)Compounds with DL ge018 (average value for Drugbank)were selected as bioactive compounds in XFZYD

In summary compounds with OB ge30 and DLge018were selected for subsequent research and others wereexcluded The criteria used here were mainly for (1) extract-ing information from the herbs as much as possible with theleast number of components and (2) explaining the obtainedmodel by the reported pharmacological data

23 Target Prediction To obtain the molecular targets ofthese active ingredients an in-house developedmodel SysDTbased on Random Forest (RF) and Support Vector Machine(SVM) methods [47] was proposed which efficiently inte-grated large-scale information on chemistry genomics andpharmacology This approach shows impressive performanceof prediction for drug-target interactions with a concordanceof 8283 a sensitivity of 8133 and a specificity of 9362

respectively [40] UniProtKB (httpwwwuniprotorg) wasemployed to obtain the standard name of the predicted targetproteins

24 TBI-Specific Protein Collecting The known therapeutictarget proteins of TBI were screened fromTherapeutic TargetDatabase (TTD available httpbiddnusedusggroupcjttd)TTD is a publicly accessible database which provides com-prehensive information about the known therapeutic proteinand nucleic acid targets described in the literature thetargeted disease conditions the pathway information and thecorresponding drugsligands directed at each of these targets[48] We also searched for Online Mendelian Inheritancein Man database (OMIM available httpomimorg) toget proteins related to TBI OMIM catalogues all knowndiseases with a genetic component and then possibly linksthem to the relevant genes in the human genome andprovides references for further research and tools for genomicanalysis of a catalogued gene [49] Then the proteinsacquired from both databases were used as hub proteinsand submitted to Human protein Reference Database [50](HPRD available httpwwwhprdorg) and STRING [51](httpsstring-dborg) to generate the proteins interactingwith these hub proteins HPRD is a database containingcurated proteomic information pertaining to human pro-teins The human protein-protein interaction (PPI) data onHPRD (Release 9) consists of 39240 interactions among 9617genesThe STRINGdatabase provides both experimental andpredicted interaction information providing a probabilisticassociation confidence score

25 Molecule Docking The LibDock algorithm based on theCHARMm Force Field in Discovery Studio (DS) 25 wasused in this study to evaluate the potential molecular bindingmode between bioactive compounds and putative targetsThecrystal structure of the target proteins of XFZYD for treatingTBI was downloaded from the RCSB Protein Data Bank(wwwrcsborg) The 3D chemical structures of bioactivecompounds were downloaded from PubMed Compounddatabase or TCMSP database and subjected to minimize theenergy by using molecular mechanics-2 (MM2) force fieldThe protein preparation protocol was used before dockingsuch as inserting missing atoms in incomplete residuesremoving water and protonating titratable residues The lig-and preparation protocol was employed before docking suchas removing duplicates enumerating isomers and generating3D conformations The protein-ligand docking active sitewas defined by the location of the original ligand All otherdocking and consequent scoring parameters were kept attheir default settings The compound was considered to be apotentially active ingredient if the LibDock score was higherthan the original ligand

26 Network Construction and Analysis Network construc-tion was performed as follows

(1) The herbs candidate compounds and candidate tar-gets of XFZYD were used to construct an herb-candidate compound-candidate target (HB-cC-cT)network

(2) The PPI data obtained above was used to establish theTBI-specific protein interaction network

(3) Herbs potential compounds and putative targetsfrom XFZYD for treating TBI were used to builda herb-potential compounds-potential targets (HB-pC-pT) network

(4) Potential targets and the biology process they partici-pate in were used to construct the pT-F network

(5) Compounds and targets through molecule dockingvalidating were used to build a compound-target (C-T) network

All networks were generated and analyzed by Cytoscape 340[52] an open source of bioinformatic package for biologicalnetwork analysis and visualization Two topological param-eters including degree and betweenness were calculated forthe obtained networks which disclose the significance ofa node

27 Gene Ontology (GO) and Pathway Enrichment Analy-sis The functional enrichment tool DAVID [53] (DAVIDhttpsdavidncifcrfgov) ver 68) was used to calculateboth the KEGG pathway and GO biological processes (BP)enrichment

28 Statistical Analysis All data were expressed as mean plusmnstandard deviation (SD) The molecule descriptors data wereanalyzed by one-way ANOVA The criterion for statisticalsignificance was p lt 005 Statistical analyses were conductedusing the SPSS 240

3 Results

TCM an experience-based medicine has been widely usedfor thousands of years It has accumulated abundant clinicalexperience forming a comprehensive and unique medicalsystem [35] The complexity of the phytochemical compo-nents makes it extremely difficult to illustrate the actionmechanisms of XFZYD from a molecule or system levelAs a chief mean of treating diseases clinically generallyTCM doctors prescribe formula based on the principle ofldquoJun-Chen-Zuo-Shirdquo ldquoJunrdquo (monarch) treats the main causeor primary symptoms of the disease ldquoChenrdquo (minister)enhances the actions of ldquoJunrdquo or treats the accompanyingsymptoms ldquoZuordquo (adjuvant) not only reduces or eliminatesthe possible toxic effects of the Jun or Chen but also treatsthe accompanying symptoms ldquoShirdquo (guide) helps to deliveror guide the other herbs to the target organs [18] Accordingto the unique feature of TCM ourwork tried to perform ldquoJun-Chen-Zuo-Shirdquo based system study to clarify the multiplemechanisms of XFZYD in the treatment of TBI

31 Herbal Ingredient Comparison and Target Predictionof XFZYD We obtained 162 components originated fromXFZYD Of these compounds 160 chemicals that were inaccord with standard requirements were searched from theTCMSP database The other 2 components amygdalin andhydroxysafflor yellow A were taken into consideration fortheir obvious pharmacological action as well The detailedinformation of these compounds is showed in Table S1Persicae Semen (Tao ren) and Carthami Flos (Hong hua)the Jun (monarch) herbs of XFZYD contained 36 bioactivecomponents which accounted for 22 of the 162 chemicalsRadix Paeoniae Rubra (Chi shao) Chuanxiong Rhizoma(Chuan xiong) andAchyranthis Bidentatae Radix (Niu xi) theChen (minister) herbs contained 31 bioactive componentswhich accounted for 19 of the 162 chemicals AngelicaeSinensis Radix (Dang gui) Rehmannia glutinosa Libosch(Sheng di huang) Platycodon Grandiforus (Jie geng) AurantiiFructus (zhi ke) Radix Bupleuri (chai hu) and licorice (Gancao) the Zuo-Shi (adjuvant and guide) herbs of XFZYDcontained 109 bioactive components which accounted for67 of the 162 chemicals Ingredients from these herbswere compared based on the 6 important drug-associateddescriptors including molecular weight (MW) number ofhydrogen-bond donors (nHdon) number of hydrogen-bondacceptors (nHacc) partition coefficient between octanol andwater (AlogP) oral bioavailability (OB) and drug-likeness(DL)The distributions of the 6 descriptors of the ingredientsfrom the three groups are shown in Table 1 and Figure 2 Wefoundno significant differences in the values ofMW(p=016)nHdon (p=032) nHacc (p=061) and AlogP (p=082) amongthe 3 groups However the average OB value of compoundsfrom the march herbs is 5559plusmn2391 which was significantlydifferent from the Chen herbs (OB=4564plusmn1327 P=0004)and the Zuo-Shi herbs (OB=4877plusmn1505 P=0021) Thefollowing 2 groups had no significant difference in OBvalue (P=0272) As for DL the Chen herbs revealed thehighest DL index (053plusmn023) which displayed significantdifference from the Zuo-Shi herbs (044plusmn019 p=0012) while

32 Target Prediction of XFZYD A total of 285 potentialtargets from the 162 compounds were generated using thetarget prediction model The amounts of potential targets hitby the Jun Chen and Zuo-Shi drugs were 217 218 and 261respectively The detailed data of the targets is shown in TableS2 As depicted in Figure 3(b) there was a significant targetoverlap among the 3 groups (189 candidate targets) but lessoverlap between the Jun andChenherbs (9 candidate targets)The number of targets shared by the Jun and Zuo-Shi herbswas 14 while 10 targets were overlapped between the Chenand Zuo-Shi herbs

33 HB-cC-cT Network Construction and Analysis We nextestablished aHB-cC-cT network through network analysis toilluminate the relationship among the herbs candidate com-pounds and candidate targets (Figure 3(c)) This networkconsisted of 485 nodes (11 herbs 162 candidate compoundsand 285 candidate targets) and 2585 edges A herb (triangle)and cC (square) are connected if the compound is containedin this herb and the edges between cC and cT represent theinteraction The size of nodes is proportional to the valueof degree The larger size of the node means more phar-macologically important Two centrality indicators degreeand betweenness identify the important nodes within thenetwork Different centralities reflect different importanceof nodes in a network from different angles Interestingly

both of the two types of centrality indicators uniformlyconfirmed themost important 10 candidate compounds fromXFZYD and the top 10 targets anchored by XFZYD (Tables2 and 3) Figure 3(c) demonstrated that licorice possessedthe largest degree (88) compared with other herbs originatedfrom XFZYD This implicated that it contained the mostbioactive compounds (88) including quercetin (Mol 148degree=153) kaempferol (Mol 108 degree=65) 7-Methoxy-2-methyl isoflavone (Mol 33 degree=44) formononetin (Mol63 degree=39) naringenin (Mol 133 degree=39) isorham-netin (Mol 105 degree=38) medicarpin (Mol 131 degree=35)and licochalcone a (Mol 113 degree=33) followed byPersicae Semen (degree=19) Carthami Flos (degree=18)Achyranthis Bidentatae Radix (degree=17) Radix PaeoniaeRubra (degree=14) Radix Bupleuri (degree=12) ChuanxiongRhizoma (degree=6) Aurantii Fructus (degree=4) Platy-codon Grandiforus (degree=4) Rehmannia glutinosa Libosch(degree=3) andAngelicae Sinensis Radix (degree=2) PersicaeSemen (degree=19) and Carthami Flos (degree=18) the Junherbs from XFZYD possessed 29 specific compounds and5 unique target proteins including ALB CTNNB1 MMP10LYZ andNFKB1 Twenty-three Chen-specific potential com-pounds targeted 10 specific proteins including CD14 LBPNR3C1 BBC3 TEP1 PRKCD FN1 PDE10A GSTA1 andGSTA2 The Zuo-Shi herbs possessed the largest number ofspecific compounds (101) and 48 unique proteins such asHTR3A ADRA1D PYGM OLR1 CHRM5 RXRB STAT3MAPK10 OPRD1 and MAPK3 There were 189 proteinsanchored by the Jun Chen and Zuo-Shi drugs

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

where X represents the molecular descriptors of herb com-pounds and Y is the average molecular properties of all com-pounds in Drugbank database (httpwwwdrugbankca)Compounds with DL ge018 (average value for Drugbank)were selected as bioactive compounds in XFZYD

In summary compounds with OB ge30 and DLge018were selected for subsequent research and others wereexcluded The criteria used here were mainly for (1) extract-ing information from the herbs as much as possible with theleast number of components and (2) explaining the obtainedmodel by the reported pharmacological data

23 Target Prediction To obtain the molecular targets ofthese active ingredients an in-house developedmodel SysDTbased on Random Forest (RF) and Support Vector Machine(SVM) methods [47] was proposed which efficiently inte-grated large-scale information on chemistry genomics andpharmacology This approach shows impressive performanceof prediction for drug-target interactions with a concordanceof 8283 a sensitivity of 8133 and a specificity of 9362

respectively [40] UniProtKB (httpwwwuniprotorg) wasemployed to obtain the standard name of the predicted targetproteins

24 TBI-Specific Protein Collecting The known therapeutictarget proteins of TBI were screened fromTherapeutic TargetDatabase (TTD available httpbiddnusedusggroupcjttd)TTD is a publicly accessible database which provides com-prehensive information about the known therapeutic proteinand nucleic acid targets described in the literature thetargeted disease conditions the pathway information and thecorresponding drugsligands directed at each of these targets[48] We also searched for Online Mendelian Inheritancein Man database (OMIM available httpomimorg) toget proteins related to TBI OMIM catalogues all knowndiseases with a genetic component and then possibly linksthem to the relevant genes in the human genome andprovides references for further research and tools for genomicanalysis of a catalogued gene [49] Then the proteinsacquired from both databases were used as hub proteinsand submitted to Human protein Reference Database [50](HPRD available httpwwwhprdorg) and STRING [51](httpsstring-dborg) to generate the proteins interactingwith these hub proteins HPRD is a database containingcurated proteomic information pertaining to human pro-teins The human protein-protein interaction (PPI) data onHPRD (Release 9) consists of 39240 interactions among 9617genesThe STRINGdatabase provides both experimental andpredicted interaction information providing a probabilisticassociation confidence score

25 Molecule Docking The LibDock algorithm based on theCHARMm Force Field in Discovery Studio (DS) 25 wasused in this study to evaluate the potential molecular bindingmode between bioactive compounds and putative targetsThecrystal structure of the target proteins of XFZYD for treatingTBI was downloaded from the RCSB Protein Data Bank(wwwrcsborg) The 3D chemical structures of bioactivecompounds were downloaded from PubMed Compounddatabase or TCMSP database and subjected to minimize theenergy by using molecular mechanics-2 (MM2) force fieldThe protein preparation protocol was used before dockingsuch as inserting missing atoms in incomplete residuesremoving water and protonating titratable residues The lig-and preparation protocol was employed before docking suchas removing duplicates enumerating isomers and generating3D conformations The protein-ligand docking active sitewas defined by the location of the original ligand All otherdocking and consequent scoring parameters were kept attheir default settings The compound was considered to be apotentially active ingredient if the LibDock score was higherthan the original ligand

26 Network Construction and Analysis Network construc-tion was performed as follows

(1) The herbs candidate compounds and candidate tar-gets of XFZYD were used to construct an herb-candidate compound-candidate target (HB-cC-cT)network

(2) The PPI data obtained above was used to establish theTBI-specific protein interaction network

(3) Herbs potential compounds and putative targetsfrom XFZYD for treating TBI were used to builda herb-potential compounds-potential targets (HB-pC-pT) network

(4) Potential targets and the biology process they partici-pate in were used to construct the pT-F network

(5) Compounds and targets through molecule dockingvalidating were used to build a compound-target (C-T) network

All networks were generated and analyzed by Cytoscape 340[52] an open source of bioinformatic package for biologicalnetwork analysis and visualization Two topological param-eters including degree and betweenness were calculated forthe obtained networks which disclose the significance ofa node

27 Gene Ontology (GO) and Pathway Enrichment Analy-sis The functional enrichment tool DAVID [53] (DAVIDhttpsdavidncifcrfgov) ver 68) was used to calculateboth the KEGG pathway and GO biological processes (BP)enrichment

28 Statistical Analysis All data were expressed as mean plusmnstandard deviation (SD) The molecule descriptors data wereanalyzed by one-way ANOVA The criterion for statisticalsignificance was p lt 005 Statistical analyses were conductedusing the SPSS 240

3 Results

TCM an experience-based medicine has been widely usedfor thousands of years It has accumulated abundant clinicalexperience forming a comprehensive and unique medicalsystem [35] The complexity of the phytochemical compo-nents makes it extremely difficult to illustrate the actionmechanisms of XFZYD from a molecule or system levelAs a chief mean of treating diseases clinically generallyTCM doctors prescribe formula based on the principle ofldquoJun-Chen-Zuo-Shirdquo ldquoJunrdquo (monarch) treats the main causeor primary symptoms of the disease ldquoChenrdquo (minister)enhances the actions of ldquoJunrdquo or treats the accompanyingsymptoms ldquoZuordquo (adjuvant) not only reduces or eliminatesthe possible toxic effects of the Jun or Chen but also treatsthe accompanying symptoms ldquoShirdquo (guide) helps to deliveror guide the other herbs to the target organs [18] Accordingto the unique feature of TCM ourwork tried to perform ldquoJun-Chen-Zuo-Shirdquo based system study to clarify the multiplemechanisms of XFZYD in the treatment of TBI

31 Herbal Ingredient Comparison and Target Predictionof XFZYD We obtained 162 components originated fromXFZYD Of these compounds 160 chemicals that were inaccord with standard requirements were searched from theTCMSP database The other 2 components amygdalin andhydroxysafflor yellow A were taken into consideration fortheir obvious pharmacological action as well The detailedinformation of these compounds is showed in Table S1Persicae Semen (Tao ren) and Carthami Flos (Hong hua)the Jun (monarch) herbs of XFZYD contained 36 bioactivecomponents which accounted for 22 of the 162 chemicalsRadix Paeoniae Rubra (Chi shao) Chuanxiong Rhizoma(Chuan xiong) andAchyranthis Bidentatae Radix (Niu xi) theChen (minister) herbs contained 31 bioactive componentswhich accounted for 19 of the 162 chemicals AngelicaeSinensis Radix (Dang gui) Rehmannia glutinosa Libosch(Sheng di huang) Platycodon Grandiforus (Jie geng) AurantiiFructus (zhi ke) Radix Bupleuri (chai hu) and licorice (Gancao) the Zuo-Shi (adjuvant and guide) herbs of XFZYDcontained 109 bioactive components which accounted for67 of the 162 chemicals Ingredients from these herbswere compared based on the 6 important drug-associateddescriptors including molecular weight (MW) number ofhydrogen-bond donors (nHdon) number of hydrogen-bondacceptors (nHacc) partition coefficient between octanol andwater (AlogP) oral bioavailability (OB) and drug-likeness(DL)The distributions of the 6 descriptors of the ingredientsfrom the three groups are shown in Table 1 and Figure 2 Wefoundno significant differences in the values ofMW(p=016)nHdon (p=032) nHacc (p=061) and AlogP (p=082) amongthe 3 groups However the average OB value of compoundsfrom the march herbs is 5559plusmn2391 which was significantlydifferent from the Chen herbs (OB=4564plusmn1327 P=0004)and the Zuo-Shi herbs (OB=4877plusmn1505 P=0021) Thefollowing 2 groups had no significant difference in OBvalue (P=0272) As for DL the Chen herbs revealed thehighest DL index (053plusmn023) which displayed significantdifference from the Zuo-Shi herbs (044plusmn019 p=0012) while

32 Target Prediction of XFZYD A total of 285 potentialtargets from the 162 compounds were generated using thetarget prediction model The amounts of potential targets hitby the Jun Chen and Zuo-Shi drugs were 217 218 and 261respectively The detailed data of the targets is shown in TableS2 As depicted in Figure 3(b) there was a significant targetoverlap among the 3 groups (189 candidate targets) but lessoverlap between the Jun andChenherbs (9 candidate targets)The number of targets shared by the Jun and Zuo-Shi herbswas 14 while 10 targets were overlapped between the Chenand Zuo-Shi herbs

33 HB-cC-cT Network Construction and Analysis We nextestablished aHB-cC-cT network through network analysis toilluminate the relationship among the herbs candidate com-pounds and candidate targets (Figure 3(c)) This networkconsisted of 485 nodes (11 herbs 162 candidate compoundsand 285 candidate targets) and 2585 edges A herb (triangle)and cC (square) are connected if the compound is containedin this herb and the edges between cC and cT represent theinteraction The size of nodes is proportional to the valueof degree The larger size of the node means more phar-macologically important Two centrality indicators degreeand betweenness identify the important nodes within thenetwork Different centralities reflect different importanceof nodes in a network from different angles Interestingly

both of the two types of centrality indicators uniformlyconfirmed themost important 10 candidate compounds fromXFZYD and the top 10 targets anchored by XFZYD (Tables2 and 3) Figure 3(c) demonstrated that licorice possessedthe largest degree (88) compared with other herbs originatedfrom XFZYD This implicated that it contained the mostbioactive compounds (88) including quercetin (Mol 148degree=153) kaempferol (Mol 108 degree=65) 7-Methoxy-2-methyl isoflavone (Mol 33 degree=44) formononetin (Mol63 degree=39) naringenin (Mol 133 degree=39) isorham-netin (Mol 105 degree=38) medicarpin (Mol 131 degree=35)and licochalcone a (Mol 113 degree=33) followed byPersicae Semen (degree=19) Carthami Flos (degree=18)Achyranthis Bidentatae Radix (degree=17) Radix PaeoniaeRubra (degree=14) Radix Bupleuri (degree=12) ChuanxiongRhizoma (degree=6) Aurantii Fructus (degree=4) Platy-codon Grandiforus (degree=4) Rehmannia glutinosa Libosch(degree=3) andAngelicae Sinensis Radix (degree=2) PersicaeSemen (degree=19) and Carthami Flos (degree=18) the Junherbs from XFZYD possessed 29 specific compounds and5 unique target proteins including ALB CTNNB1 MMP10LYZ andNFKB1 Twenty-three Chen-specific potential com-pounds targeted 10 specific proteins including CD14 LBPNR3C1 BBC3 TEP1 PRKCD FN1 PDE10A GSTA1 andGSTA2 The Zuo-Shi herbs possessed the largest number ofspecific compounds (101) and 48 unique proteins such asHTR3A ADRA1D PYGM OLR1 CHRM5 RXRB STAT3MAPK10 OPRD1 and MAPK3 There were 189 proteinsanchored by the Jun Chen and Zuo-Shi drugs

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

25 Molecule Docking The LibDock algorithm based on theCHARMm Force Field in Discovery Studio (DS) 25 wasused in this study to evaluate the potential molecular bindingmode between bioactive compounds and putative targetsThecrystal structure of the target proteins of XFZYD for treatingTBI was downloaded from the RCSB Protein Data Bank(wwwrcsborg) The 3D chemical structures of bioactivecompounds were downloaded from PubMed Compounddatabase or TCMSP database and subjected to minimize theenergy by using molecular mechanics-2 (MM2) force fieldThe protein preparation protocol was used before dockingsuch as inserting missing atoms in incomplete residuesremoving water and protonating titratable residues The lig-and preparation protocol was employed before docking suchas removing duplicates enumerating isomers and generating3D conformations The protein-ligand docking active sitewas defined by the location of the original ligand All otherdocking and consequent scoring parameters were kept attheir default settings The compound was considered to be apotentially active ingredient if the LibDock score was higherthan the original ligand

26 Network Construction and Analysis Network construc-tion was performed as follows

(1) The herbs candidate compounds and candidate tar-gets of XFZYD were used to construct an herb-candidate compound-candidate target (HB-cC-cT)network

(2) The PPI data obtained above was used to establish theTBI-specific protein interaction network

(3) Herbs potential compounds and putative targetsfrom XFZYD for treating TBI were used to builda herb-potential compounds-potential targets (HB-pC-pT) network

(4) Potential targets and the biology process they partici-pate in were used to construct the pT-F network

(5) Compounds and targets through molecule dockingvalidating were used to build a compound-target (C-T) network

All networks were generated and analyzed by Cytoscape 340[52] an open source of bioinformatic package for biologicalnetwork analysis and visualization Two topological param-eters including degree and betweenness were calculated forthe obtained networks which disclose the significance ofa node

27 Gene Ontology (GO) and Pathway Enrichment Analy-sis The functional enrichment tool DAVID [53] (DAVIDhttpsdavidncifcrfgov) ver 68) was used to calculateboth the KEGG pathway and GO biological processes (BP)enrichment

28 Statistical Analysis All data were expressed as mean plusmnstandard deviation (SD) The molecule descriptors data wereanalyzed by one-way ANOVA The criterion for statisticalsignificance was p lt 005 Statistical analyses were conductedusing the SPSS 240

TCM an experience-based medicine has been widely usedfor thousands of years It has accumulated abundant clinicalexperience forming a comprehensive and unique medicalsystem [35] The complexity of the phytochemical compo-nents makes it extremely difficult to illustrate the actionmechanisms of XFZYD from a molecule or system levelAs a chief mean of treating diseases clinically generallyTCM doctors prescribe formula based on the principle ofldquoJun-Chen-Zuo-Shirdquo ldquoJunrdquo (monarch) treats the main causeor primary symptoms of the disease ldquoChenrdquo (minister)enhances the actions of ldquoJunrdquo or treats the accompanyingsymptoms ldquoZuordquo (adjuvant) not only reduces or eliminatesthe possible toxic effects of the Jun or Chen but also treatsthe accompanying symptoms ldquoShirdquo (guide) helps to deliveror guide the other herbs to the target organs [18] Accordingto the unique feature of TCM ourwork tried to perform ldquoJun-Chen-Zuo-Shirdquo based system study to clarify the multiplemechanisms of XFZYD in the treatment of TBI

31 Herbal Ingredient Comparison and Target Predictionof XFZYD We obtained 162 components originated fromXFZYD Of these compounds 160 chemicals that were inaccord with standard requirements were searched from theTCMSP database The other 2 components amygdalin andhydroxysafflor yellow A were taken into consideration fortheir obvious pharmacological action as well The detailedinformation of these compounds is showed in Table S1Persicae Semen (Tao ren) and Carthami Flos (Hong hua)the Jun (monarch) herbs of XFZYD contained 36 bioactivecomponents which accounted for 22 of the 162 chemicalsRadix Paeoniae Rubra (Chi shao) Chuanxiong Rhizoma(Chuan xiong) andAchyranthis Bidentatae Radix (Niu xi) theChen (minister) herbs contained 31 bioactive componentswhich accounted for 19 of the 162 chemicals AngelicaeSinensis Radix (Dang gui) Rehmannia glutinosa Libosch(Sheng di huang) Platycodon Grandiforus (Jie geng) AurantiiFructus (zhi ke) Radix Bupleuri (chai hu) and licorice (Gancao) the Zuo-Shi (adjuvant and guide) herbs of XFZYDcontained 109 bioactive components which accounted for67 of the 162 chemicals Ingredients from these herbswere compared based on the 6 important drug-associateddescriptors including molecular weight (MW) number ofhydrogen-bond donors (nHdon) number of hydrogen-bondacceptors (nHacc) partition coefficient between octanol andwater (AlogP) oral bioavailability (OB) and drug-likeness(DL)The distributions of the 6 descriptors of the ingredientsfrom the three groups are shown in Table 1 and Figure 2 Wefoundno significant differences in the values ofMW(p=016)nHdon (p=032) nHacc (p=061) and AlogP (p=082) amongthe 3 groups However the average OB value of compoundsfrom the march herbs is 5559plusmn2391 which was significantlydifferent from the Chen herbs (OB=4564plusmn1327 P=0004)and the Zuo-Shi herbs (OB=4877plusmn1505 P=0021) Thefollowing 2 groups had no significant difference in OBvalue (P=0272) As for DL the Chen herbs revealed thehighest DL index (053plusmn023) which displayed significantdifference from the Zuo-Shi herbs (044plusmn019 p=0012) while

32 Target Prediction of XFZYD A total of 285 potentialtargets from the 162 compounds were generated using thetarget prediction model The amounts of potential targets hitby the Jun Chen and Zuo-Shi drugs were 217 218 and 261respectively The detailed data of the targets is shown in TableS2 As depicted in Figure 3(b) there was a significant targetoverlap among the 3 groups (189 candidate targets) but lessoverlap between the Jun andChenherbs (9 candidate targets)The number of targets shared by the Jun and Zuo-Shi herbswas 14 while 10 targets were overlapped between the Chenand Zuo-Shi herbs

33 HB-cC-cT Network Construction and Analysis We nextestablished aHB-cC-cT network through network analysis toilluminate the relationship among the herbs candidate com-pounds and candidate targets (Figure 3(c)) This networkconsisted of 485 nodes (11 herbs 162 candidate compoundsand 285 candidate targets) and 2585 edges A herb (triangle)and cC (square) are connected if the compound is containedin this herb and the edges between cC and cT represent theinteraction The size of nodes is proportional to the valueof degree The larger size of the node means more phar-macologically important Two centrality indicators degreeand betweenness identify the important nodes within thenetwork Different centralities reflect different importanceof nodes in a network from different angles Interestingly

both of the two types of centrality indicators uniformlyconfirmed themost important 10 candidate compounds fromXFZYD and the top 10 targets anchored by XFZYD (Tables2 and 3) Figure 3(c) demonstrated that licorice possessedthe largest degree (88) compared with other herbs originatedfrom XFZYD This implicated that it contained the mostbioactive compounds (88) including quercetin (Mol 148degree=153) kaempferol (Mol 108 degree=65) 7-Methoxy-2-methyl isoflavone (Mol 33 degree=44) formononetin (Mol63 degree=39) naringenin (Mol 133 degree=39) isorham-netin (Mol 105 degree=38) medicarpin (Mol 131 degree=35)and licochalcone a (Mol 113 degree=33) followed byPersicae Semen (degree=19) Carthami Flos (degree=18)Achyranthis Bidentatae Radix (degree=17) Radix PaeoniaeRubra (degree=14) Radix Bupleuri (degree=12) ChuanxiongRhizoma (degree=6) Aurantii Fructus (degree=4) Platy-codon Grandiforus (degree=4) Rehmannia glutinosa Libosch(degree=3) andAngelicae Sinensis Radix (degree=2) PersicaeSemen (degree=19) and Carthami Flos (degree=18) the Junherbs from XFZYD possessed 29 specific compounds and5 unique target proteins including ALB CTNNB1 MMP10LYZ andNFKB1 Twenty-three Chen-specific potential com-pounds targeted 10 specific proteins including CD14 LBPNR3C1 BBC3 TEP1 PRKCD FN1 PDE10A GSTA1 andGSTA2 The Zuo-Shi herbs possessed the largest number ofspecific compounds (101) and 48 unique proteins such asHTR3A ADRA1D PYGM OLR1 CHRM5 RXRB STAT3MAPK10 OPRD1 and MAPK3 There were 189 proteinsanchored by the Jun Chen and Zuo-Shi drugs

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

excitotoxicity or reparative events including angiogenesisscarring and neurogenesis [83] Function analysis of the 47target proteins regulated by XFZYD was mainly associatedwith core pathophysiology process of TBI (Figure 7) 47 targetproteins were connected with 16 key process related to TBIMost of the targets have one or more links to other biolog-ical process such as apoptosis cell proliferation superoxideanion generation nitric oxide biosynthetic process responseto calcium ion I-kappaB kinaseNF-kappaB signaling andregulation of inflammation The above analysis implied themultifunction character of these target proteins regulated byXFZYD Of these target proteins 25 proteins (53 of the 47)such as TGFB1 EGFR CAV1 MAPK1 PRKCB and AKT1were responsible for regulating the apoptosis process 17 forblood coagulation 14 for cell proliferation and axon genesisand 12 for hypoxia andMAPK cascade We found that TGFB1was the crucial protein because it participated in 9 biologicalprocesses related to TBI such as apoptosis blood coagulationcell proliferation and MAPK cascade followed by EGFR (8)CAV1 (7) MAPK1 (6) PRKCB (6) and AKT1 (6)

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

33 HB-cC-cT Network Construction and Analysis We nextestablished aHB-cC-cT network through network analysis toilluminate the relationship among the herbs candidate com-pounds and candidate targets (Figure 3(c)) This networkconsisted of 485 nodes (11 herbs 162 candidate compoundsand 285 candidate targets) and 2585 edges A herb (triangle)and cC (square) are connected if the compound is containedin this herb and the edges between cC and cT represent theinteraction The size of nodes is proportional to the valueof degree The larger size of the node means more phar-macologically important Two centrality indicators degreeand betweenness identify the important nodes within thenetwork Different centralities reflect different importanceof nodes in a network from different angles Interestingly

both of the two types of centrality indicators uniformlyconfirmed themost important 10 candidate compounds fromXFZYD and the top 10 targets anchored by XFZYD (Tables2 and 3) Figure 3(c) demonstrated that licorice possessedthe largest degree (88) compared with other herbs originatedfrom XFZYD This implicated that it contained the mostbioactive compounds (88) including quercetin (Mol 148degree=153) kaempferol (Mol 108 degree=65) 7-Methoxy-2-methyl isoflavone (Mol 33 degree=44) formononetin (Mol63 degree=39) naringenin (Mol 133 degree=39) isorham-netin (Mol 105 degree=38) medicarpin (Mol 131 degree=35)and licochalcone a (Mol 113 degree=33) followed byPersicae Semen (degree=19) Carthami Flos (degree=18)Achyranthis Bidentatae Radix (degree=17) Radix PaeoniaeRubra (degree=14) Radix Bupleuri (degree=12) ChuanxiongRhizoma (degree=6) Aurantii Fructus (degree=4) Platy-codon Grandiforus (degree=4) Rehmannia glutinosa Libosch(degree=3) andAngelicae Sinensis Radix (degree=2) PersicaeSemen (degree=19) and Carthami Flos (degree=18) the Junherbs from XFZYD possessed 29 specific compounds and5 unique target proteins including ALB CTNNB1 MMP10LYZ andNFKB1 Twenty-three Chen-specific potential com-pounds targeted 10 specific proteins including CD14 LBPNR3C1 BBC3 TEP1 PRKCD FN1 PDE10A GSTA1 andGSTA2 The Zuo-Shi herbs possessed the largest number ofspecific compounds (101) and 48 unique proteins such asHTR3A ADRA1D PYGM OLR1 CHRM5 RXRB STAT3MAPK10 OPRD1 and MAPK3 There were 189 proteinsanchored by the Jun Chen and Zuo-Shi drugs

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

excitotoxicity or reparative events including angiogenesisscarring and neurogenesis [83] Function analysis of the 47target proteins regulated by XFZYD was mainly associatedwith core pathophysiology process of TBI (Figure 7) 47 targetproteins were connected with 16 key process related to TBIMost of the targets have one or more links to other biolog-ical process such as apoptosis cell proliferation superoxideanion generation nitric oxide biosynthetic process responseto calcium ion I-kappaB kinaseNF-kappaB signaling andregulation of inflammation The above analysis implied themultifunction character of these target proteins regulated byXFZYD Of these target proteins 25 proteins (53 of the 47)such as TGFB1 EGFR CAV1 MAPK1 PRKCB and AKT1were responsible for regulating the apoptosis process 17 forblood coagulation 14 for cell proliferation and axon genesisand 12 for hypoxia andMAPK cascade We found that TGFB1was the crucial protein because it participated in 9 biologicalprocesses related to TBI such as apoptosis blood coagulationcell proliferation and MAPK cascade followed by EGFR (8)CAV1 (7) MAPK1 (6) PRKCB (6) and AKT1 (6)

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

excitotoxicity or reparative events including angiogenesisscarring and neurogenesis [83] Function analysis of the 47target proteins regulated by XFZYD was mainly associatedwith core pathophysiology process of TBI (Figure 7) 47 targetproteins were connected with 16 key process related to TBIMost of the targets have one or more links to other biolog-ical process such as apoptosis cell proliferation superoxideanion generation nitric oxide biosynthetic process responseto calcium ion I-kappaB kinaseNF-kappaB signaling andregulation of inflammation The above analysis implied themultifunction character of these target proteins regulated byXFZYD Of these target proteins 25 proteins (53 of the 47)such as TGFB1 EGFR CAV1 MAPK1 PRKCB and AKT1were responsible for regulating the apoptosis process 17 forblood coagulation 14 for cell proliferation and axon genesisand 12 for hypoxia andMAPK cascade We found that TGFB1was the crucial protein because it participated in 9 biologicalprocesses related to TBI such as apoptosis blood coagulationcell proliferation and MAPK cascade followed by EGFR (8)CAV1 (7) MAPK1 (6) PRKCB (6) and AKT1 (6)

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

The analysis of the network revealed that quercetin (Mol148) kaempferol (Mol 108) luteolin (Mol 127) wogonin (Mol160) 7-Methoxy-2-methyl (Mol 33) and beta-sitosterol (Mol41) were predicted as the major active compounds of XFZYDTheproteins including F2 NOS2 PTGS1 PTGS2 and CALMwere predicted as essential pharmacological proteins for thetherapeutic effects of XFZYD

34 Analyses on TBI Based Specific Protein Interaction Net-work Network biology integrated with different kinds ofdata including physical or functional networks and diseasegene sets is used to interpret humandiseases Protein-proteininteraction networks (PPI) are fundamental to understandthe cellular organizations biological processes and proteinfunctions [54] From the systematic perspective the analysisof TBI-related PPI will improve the understanding of thecomplicated molecular pathways and the dynamic processesunderlying TBI We screened the TBI-specific genes andprotein targets using Online Mendelian Inheritance in Mandatabase (OMIM) and Therapeutic Target Database (TTD)Figure 4 indicated that 21 TBI-specific genesproteins wereacquired Further these hub-proteins were submitted toHPRD and STRING to establish the TBI-specific proteininteraction network The detailed information of the TBI-specific proteins is shown in Table S3 The results suggestedthat the network consisted of 489 nodes and 5738 edges(Figure 4(a)) We obtained top 10 TBI-related proteinsaccording to 2 centrality indicators generated and summa-rized in Table 4 Interestingly we found that the node withhigher betweenness tends to possess larger degree (Fig-ure 5) Network topology analysis showed that protoonco-gene tyrosine-protein kinase Src (SRC degree=164 between-ness=0059) RAC-alpha serinethreonine-protein kinase(AKT1 degree=157 betweenness=0045) Serum albumin(ALB degree=153 betweenness=0069) Epidermal growthfactor receptor (EGFR degree=139 betweenness=0053)and Amyloid beta A4 protein (APP degree=134 between-ness=0072) contributed to the essential role in the patho-physiology of TBI All of these indicated that the top mutualtarget proteins performed various beneficial functions to treatTBI at the molecular level For example SRC is activatedfollowing engagement of many different classes of cellular

receptors It participates in signal pathways that controla diverse spectrum of biological activities including genetranscription immune response cell adhesion cell cycleprogression apoptosis migration and transformation [55]SRC can result in blood-brain barrier (BBB) disruptionand brain edema at the acute stage the inhibition of SRCfamily kinases can protect hippocampal neurons and improvecognitive function after TBI [56] AKT1 regulates manyprocesses including metabolism proliferation cell survivalgrowth and angiogenesis [57] The PI3KAKTPTEN path-way has been shown to play a pivotal role in neuroprotectionenhancing cell survival by stimulating cell proliferation andinhibiting apoptosis after TBI [58] ALB is the main proteinof plasma and can be a biomarker to predict outcome ofTBI [59] Its main function is the regulation of the colloidalosmotic pressure of blood We found that it may participatein pathological process of TBI

KEGG pathway analysis was also used to determine thefunctions of proteins Table 5 describes the top 10 significantlyenriched KEGG pathways These pathways play crucial rolesin pathophysiology process which have also been widelydiscussed in existing literature For instanceMAPK signalingpathway can promote pathological axonal death throughtriggering a local energy deficit [60] Neurotrophin signalingthrough Trk receptors regulates cell survival proliferationthe fate of neural precursors axon and dendrite growth andpatterning and the expression and activity of functionallyimportant proteins such as ion channels and neurotransmit-ter receptors [61] Engagement of cells with the extracellularmatrix (ECM) proteins is crucial for various biological pro-cesses including cell adhesion differentiation and apoptosiscontributing to maintenance of tissue integrity and woundhealing [62]The 47 TBI-specific proteins targeted byXFZYD(yellow and green) were further discussed below

35 HB-pC-pT Network pT-F Network Construction andMolecule Docking Analyses of XFZYD for the Treatment ofTBI To investigate the therapeutic mechanisms of XFZYDfor the treatment of TBI a HB-pC-pT network of XFZYDfor treating TBI was built (Figure 6) 47 TBI-specific targetproteins (circles) were targeted by 119 potential compounds(squares) from XFZYD (Figure 6) Detailed information

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

Overall these observations strongly support the evidencethat the generated HB-pCminuspT network and pT-F networkhave important roles in treating TBI further validating thedrug targeting approach

Molecule docking was used to further validate the bind-ing mode between candidate compounds and their targetproteins We found that 18 TBI-specific target proteins inter-acted with 91 candidate compounds from XFZYD (Figure 8)

Other 29 target proteins were not discussed for the lackof proper protein crystal structure The detailed moleculedocking results are shown in Table S5The 6 essential proteinsincluding GSK3B AKT1 CDK1 F2 NOS3 and ACHEwere used to elucidate the exact binding mode (Figure 9)Quercetin was located within the binding cavity of AKT1 andCDK1 (Figures 9(a) and 9(b) and S1A B) Four conventionalhydrogen bonds were formed between quercetin and AKT1by interacting with the key amino acids including ILE-290 THR-211 and SER 205 Additionally 120587-120587 interactionsbetween quercetin and TRP-90 were found in the activesite which helped the stabilization of the compound at thebinding site (Figure 9(a) S1A) Figure 9(b) and S1B suggestedthat five conventional hydrogen bonds (LEU-83 ASP-146and LYS-33) and 120587-120587 interaction (PHE-80) were formedbetween quercetin and CDK1 The GSK3B-FA complexes(Figure 9(c) S1C) were stabilized by 6 hydrogen-bondinginteractions between FA and LYS-85 GLU-97 TYR-134 andARG-141 Glyasperin Bmainly bonds to F2 through hydrogenbonds by interacting with the key amino acids includingGLY-193 SER-195 and GLY-219 (Figure 9(d) S1D) andan edge-to-face 120587 minus 120587 interaction was also observed withTYR-228 The GLN-247 GLU-351 and GLY-355 from theactive site pocket of NOS3 participated in the hydrogen-bondformationwith 1-Methoxyphaseollidin (Figure 9(e) S1E)The(-)-Medicocarpin formed a total of 6 hydrogen bonds withSER-293 PHE-295 ARG-296 and TRY-341 in the active siteof ACHE (Figure 9(f) S1F) Besides an edge-to-face 120587 minus 120587

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

4 Discussion

Traumatic brain injury (TBI) is a growing public healthproblem worldwide and is a leading cause of death anddisability [84] Although major progress has been made in

understanding the pathophysiology of this injury this hasnot yet led to substantial improvements in outcome by alack of treatments which have proven successful during phaseIII trials for modern medicine [85 86] TCM rooted inthousands of years of history may offer an alternative or acomplementary strategy for the treatment of TBI XFZYDa representative formula in TCM has been used for yearsto treat TBI in China and has been demonstrated to beeffective in clinical practice However its ldquomulticomponentsrdquoand ldquomultitargetsrdquo features make it much difficult to decipherthemolecular mechanisms of XFZYD in the treatment of TBIfrom a systematic perspective if employing routine methods

In the present study a network pharmacology-basedmethod was employed to elucidate the pharmacologicalmechanisms of XFZYD to treat TBI according to the drug

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

activation of apoptosis processes [98] as well as higher brainfunctions such as learning andmemory [99]The activators ofPKCare effective for the treatment of TBI [100] FurthermoreMitogen-activated protein kinase 3 (MAPK3) Beta-secretase1 (BACE1) Ephrin type-B receptor 2 (EphB) and low-densitylipoprotein receptor (LDLR) were specifically targeted bythe ingredients in the Zuo-Shi herbs Naringenin (Mol133) targeted LDLR MAPK3 while euchrenone (Mol 60)anchored BACE1 and nobiletin (Mol 134) targeted EphB2MAPK3 is an essential component of the MAP kinase signaltransduction pathway It has been appreciated recently thatthe ERK12 cascade plays a fundamental role in synapticplasticity and memory [101] BACE1 is responsible for pro-duction of A120573 from amyloid precursor protein (APP) A120573can cause cell death activate inflammatory pathways [102]and prime proapoptotic pathways for activation by otherinsults [103] The blocking of BACE1 can ameliorate motorand cognitive deficits and reduce cell loss after experimentalTBI in mice [104] EphB is localized to synaptic sites inhippocampal neurons [105] The interaction between EphBand NMDA receptors regulates excitatory synapse formation[106] LDLR acts as an important receptor that facilitatesbrain A120573 clearance and inhibits amyloid deposition [107]and then ameliorates Alzheimerrsquos disease neuropathologyafter TBI [108] The analysis above indicates the ldquoJunrdquoldquoChenrdquo and ldquoZuo-Shirdquo herbs from XFZYD trigger theirspecific targets regulation respectively for the therapeuticeffects

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

processes of TBI that referred to apoptosis inflammationcell proliferation superoxide anion generation nitric oxidebiosynthetic process response to calcium ion etc The aboveanalysis reveals that the synergistic action mechanisms ofXFZYDmay be (1) bioactive compounds overlapping amongthe different group of herbs (2) specific bioactive com-pounds from different groups of herbs targeting the sameproteins (3) specific bioactive compounds from differentgroups of herbs targeting different proteins which participatein the same pathophysiological process of the disease Toa certain degree the 5 compounds including quercetinstigmasterol kaempferol baicalin and beta-sitosterol playedessential role in XFZYD for TBI treatment MAPK3MAPK1AKT1 PRKCA TNF PRKCB EGFR BCL2 GSK3B CASP3PPP3CA and NOS3 were the main target proteins regulatedby XFZYD in the treatment of TBI

Interestingly Beta-carotene (Mol 43) from Carthami Flos(the Jun herb) specifically regulated 120573-Catenin (CTNNB1)and played critical role for curing TBI The 120573-Catenin is acritical downstream component of the Wnt pathway whichplays essential role in the regulation of mammalian neuraldevelopment [87] In vitro and in vivo studies demonstrate

that the Wnt120573-catenin pathway regulates the proliferationand differentiation of neural progenitor cells [88] Neuronaldifferentiation is induced by overexpression of 120573-cateninor the pharmacological inhibition of GSK3120573 (the phospho-rylating enzyme of 120573-catenin) [89 90] This pathway alsopromotes blood vessel formation during vascular develop-ment as well as the vascular repair process after TBI [91]In addition wogonin (Mol 160) from Achyranthis BidentataeRadix (the Chen herb) specifically targeted fibronectin (FN1)Bcl-2-binding component 3 (BBC3) and Protein KinaseC delta type (PRKCD) FN1 an important component ofthe extracellular matrix (ECM) environment promotes cellmigration neurite outgrowth and synapse formation dur-ing neural development [92] It aggregates in the injuredbrain and plays a neuroprotection role through antiapoptosisand anti-inflammation ways following TBI [93 94] BBC3namely p53 upregulated modulator of apoptosis (PUMA) iscritical for the p53-dependent apoptosis pathway which playsan important role in hippocampal neuronal loss and associ-ated cognitive deficits [95] PRKCD one of PKC isoformsactivates signal transduction pathways involved in neuronalregeneration [96] synaptic transmissionplasticity [97] and

activation of apoptosis processes [98] as well as higher brainfunctions such as learning andmemory [99]The activators ofPKCare effective for the treatment of TBI [100] FurthermoreMitogen-activated protein kinase 3 (MAPK3) Beta-secretase1 (BACE1) Ephrin type-B receptor 2 (EphB) and low-densitylipoprotein receptor (LDLR) were specifically targeted bythe ingredients in the Zuo-Shi herbs Naringenin (Mol133) targeted LDLR MAPK3 while euchrenone (Mol 60)anchored BACE1 and nobiletin (Mol 134) targeted EphB2MAPK3 is an essential component of the MAP kinase signaltransduction pathway It has been appreciated recently thatthe ERK12 cascade plays a fundamental role in synapticplasticity and memory [101] BACE1 is responsible for pro-duction of A120573 from amyloid precursor protein (APP) A120573can cause cell death activate inflammatory pathways [102]and prime proapoptotic pathways for activation by otherinsults [103] The blocking of BACE1 can ameliorate motorand cognitive deficits and reduce cell loss after experimentalTBI in mice [104] EphB is localized to synaptic sites inhippocampal neurons [105] The interaction between EphBand NMDA receptors regulates excitatory synapse formation[106] LDLR acts as an important receptor that facilitatesbrain A120573 clearance and inhibits amyloid deposition [107]and then ameliorates Alzheimerrsquos disease neuropathologyafter TBI [108] The analysis above indicates the ldquoJunrdquoldquoChenrdquo and ldquoZuo-Shirdquo herbs from XFZYD trigger theirspecific targets regulation respectively for the therapeuticeffects

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI

activation of apoptosis processes [98] as well as higher brainfunctions such as learning andmemory [99]The activators ofPKCare effective for the treatment of TBI [100] FurthermoreMitogen-activated protein kinase 3 (MAPK3) Beta-secretase1 (BACE1) Ephrin type-B receptor 2 (EphB) and low-densitylipoprotein receptor (LDLR) were specifically targeted bythe ingredients in the Zuo-Shi herbs Naringenin (Mol133) targeted LDLR MAPK3 while euchrenone (Mol 60)anchored BACE1 and nobiletin (Mol 134) targeted EphB2MAPK3 is an essential component of the MAP kinase signaltransduction pathway It has been appreciated recently thatthe ERK12 cascade plays a fundamental role in synapticplasticity and memory [101] BACE1 is responsible for pro-duction of A120573 from amyloid precursor protein (APP) A120573can cause cell death activate inflammatory pathways [102]and prime proapoptotic pathways for activation by otherinsults [103] The blocking of BACE1 can ameliorate motorand cognitive deficits and reduce cell loss after experimentalTBI in mice [104] EphB is localized to synaptic sites inhippocampal neurons [105] The interaction between EphBand NMDA receptors regulates excitatory synapse formation[106] LDLR acts as an important receptor that facilitatesbrain A120573 clearance and inhibits amyloid deposition [107]and then ameliorates Alzheimerrsquos disease neuropathologyafter TBI [108] The analysis above indicates the ldquoJunrdquoldquoChenrdquo and ldquoZuo-Shirdquo herbs from XFZYD trigger theirspecific targets regulation respectively for the therapeuticeffects

XFZYD is a very famous traditional Chinese formula inpromoting qi circulation and removing blood stasis accord-ing to TCM theory However several limited researches havedemonstrated its efficacy for treating TBI such as anti-inflammatory and synaptic regulation [30 31] which arein accord with our study However previous studies merelypartially deciphered the molecule mechanism of XFZYD fortreating TBI This study reports 119 bioactive compounds inXFZYD that target 47 TBI-specific proteins such as MAPK3MAPK1 AKT1 PRKCA TNF PRKCB and EGFR Theseproteins regulate several crucial pathophysiological processesof TBI such as apoptosis inflammation blood coagulationand axon genesis Our study demonstrates that the therapeu-tic actions of XFZYD refer to ldquomulticompoundsrdquo ldquomultitar-getsrdquo features rather than only the improvement of bloodcirculation With the help of molecule docking methodwe further validate the interactions between bioactive com-pounds and potential targets of XFZYD The hydrogen-bonding and edge-to-face 120587 minus120587 interactions play key roles inthe proteinminusligand recognition and stability This provides avaluable reference for further experimental investigations ofbioactive ingredients and therapeutic targets of XFZYD fortreating TBI

5 Conclusion

Our work successfully illuminates the efficiency of XFZYDfor the treatment of TBI as well as herb combination ruleof TCM formula Network pharmacology with moleculedocking method confirms the ldquomulticompounds multitar-getsrdquo therapeutic actions of XFZYD in the treatment of TBI

The present work may provide valuable evidence for furtherclinical application of XFZYD for treating TBI
