Objective To explore the neuroprotective effects and mechanism of Tanreqing Injection(TRQ)on treating ischemic stroke based on network pharmacology and in vivo experimental *** The chemical compounds of TRQ were retrieved based on published data,with targets retrieved from PubChem,Therapeutic Target Database and *** visualization and analysis were performed using Cytoscape,with protein-protein interaction networks derived from the STRING *** analysis was performed using Kyoto Encyclopedia of Genes Genomes pathway and Gene Ontology *** in vivo experiments,the middle cerebral artery occlusion(MCAO)model was *** volume was determined by 2,3,5-triphenyltetrazolium hydrochloride staining and protein expressions were analyzed by Western *** docking was performed to predict ligand-receptor *** We screened 81 chemical compounds in TRQ and retrieved their therapeutic *** the targets,116 were therapeutic targets for *** enrichment analysis showed that the apelin signaling pathway was a key pathway for ischemic ***,in in vivo experiment we found that administering with intraperitoneal injection of 2.5 mL/kg TRQ every 6 h could significantly reduce the infarct volume of MCAO rats(P<0.05).In addition,protein levels of the apelin receptor(APJ)/phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)pathway were increased by TRQ(P<0.05).In addition,41 chemical compounds in TRQ could bind to *** The neuroprotective effect of TRQ may be related to the APJ/PI3K/AKT signaling ***,further studies are needed to confirm the findings.
