Abstract
Objective To explore the mechanism of salvianolic acid B in the treatment of flap ischemia/reperfusion(I/R)in-jury based on network pharmacology and molecular docking.Methods The action targets of salvianolic acid B were screened based on swiss target predictiont and SuperPred database,and the effective drug targets were screened in combination with Uniprot database.GeneCards,TTD and OMIM databases were used to search the targets related to flap I/R,and then the in-tersection targets of salvianolic acid B and flap I/R were obtained,and the drug-intersection genes were uploaded to the in-teraction database String for protein-protein interaction networks(PPI).The GO and KEGG pathway enrichment analysis of potential targets of salvianolic acid B for preventing I/R in skin flaps was carried out through the David database.The select-ed core targets were used to conduct molecular docking verification between key targets and corresponding active ingredients by using CB dock.Results A total of 39 potential targets of salvianolic acid B for the treatment of flap I/R were screened,of which JUN,CASP3,MMP9,APP,MAPK1,MTOR and NFKB1 were the core targets.GO functional enrichment analysis of biological process,cell composition and molecular function entries were 91,28,24 respectively,KEGG pathway enrichment analysis found that the main pathways related to the pre-vention and treatment of flap UR:lipid and atherosclerosis,interleukin-17 signaling pathway,and tumor necrosis fac-tor signaling pathway,atherosclerosis and fluid shear stress.The molecular docking results of the active ingredi-ent and the core target showed that the active ingredient of salvianolic B had a good binding affinity and interaction mode between the three core targets with a free value greater than 15.Conclusion Salvianolic acid B plays the role of preventing and treating flap I/R from activating cell autophagy to promote angiogenesis,inhibiting cell apoptosis and oxidative stress re-sponse,and reducing the synthesis and secretion of inflammatory factors,providing a theoretical basis for the in-depth re-search of the further study of monomer regulation of"cell autophagy"关键词
