RESUMO
Stroke has been harmful to human health for a long time, and there is no satisfactory treatment strategy because of its complex pathogenesis. Taohechengqi decoction has been effective in the treatment of stroke. In this study, the components were collected by TCMSP, TCMIP, BATMAN-TCM and TCMID databases, the targets were predicted and screened by PharmMapper and BATMAN-TCM databases, and the functional enrichment analysis of the targets was carried out by using R language package clusterProfiler. Finally, the key targets are verified by GEO database and molecular docking. The results showed that 51 active components of Taohechengqi decoction may regulate 15 key targets such as nitric oxide synthase, endothelial (NOS3), prostaglandin G/H synthase 2 (PTGS2), matrix metalloproteinase-9 (MMP9), affecting vascular endothelial growth factor signaling pathway and other pathways to play a role in the prevention of stroke, affecting tumor necrosis factor signaling pathway and other pathways to play a role in the treatment of stroke. GEO data analysis showed that androgen receptor (AR), caspase-8 (CASP8), intercellular adhesion molecule 1 (ICAM1), interleukin-1 beta (IL1B), mitogen-activated protein kinase 14 (MAPK14), MMP9, myeloperoxidase (MPO), peroxisome proliferator-activated receptor gamma (PPARG), PTGS2 and cellular tumor antigen p53 (TP53) were up-regulated genes, while serum albumin (ALB), estrogen receptor 1 (ESR1), NOS3, transcription factor p65 (RELA) and proto-oncogene tyrosine-protein kinase Src (SRC) were down-regulated genes. GEO analysis explained that Taohechengqi decoction may prevent stroke by down-regulating ESR1, NOS3, and treat stroke by up-regulating ICAM1, IL1B, MAPK14, MMP9, PPARG, PTGS2, TP53, and down-regulating RELA and SRC. The study found that in the process of prevention and treatment of stroke, Taohechengqi decoction played a two-way regulation role through multi-genes and multiple ways, which provided a new strategy for the treatment of stroke.
