Objective:Network pharmacology method was adopted in this study to screen the target of Zhitong Rushen Decoction of the treatment to Functional Anorectal Pain(FAP)and explore its mechanism of treatment.Methods: Chemical components and selected targets related to the ten traditional Chinese medicine (TCM) herbs were searched through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP).Through GeneCards database,OMIM database, disease targets of FAP were searched. R language was used to screen the common targets between drugs and disease, and then the interaction network diagram of the targets was constructed by String.Cytoscape3.7.0 was applied to construct the active ingredients-targets interacted network.GO enrichment analysis and KEGG enrichment analysis of targets were based on R language.Results:Four main chemical components including quercetin, wogonin, fisetin and kaempferol were screened, and four key targets including ESR1、NOS2、PGR and CHRM3 were identified.In GO enrichment analysis, 66 molecular function entries, 1040 biological process entries, 26 cell component entries were obtained. KEGG pathway enrichment analysis showed that zhitong rushen decoction played a therapeutic role in functional anorectal pain by regulating AGE-RAGE signaling pathway in diabetic complications,Bladder cancer, Estrogen signaling pathway, HIF-1 signaling pathway. Conclusion: Zhitong rushen decoction for the treatment of functional anorectal pain may be related to its multi-component effect on multiple targets and multiple signaling pathways, providing theoretical basis for further study of active ingredients and mechanism of action.
