Objective:The mechanism of Chinese herbal medicine Bi xie and Tu fuling on the treatment of gouty arthritis was explored through network pharmacological methods. Methods:First, the TCMSP Chinese medicine system pharmacology database and analysis platform were used to define the bioavailability (OB) 30％ and drug-likeness (DL) 0.18. Database to mine genetic targets related to gouty arthritis disease. Finally, the two genes are intersected to construct a Chinese medicine regulatory network of Chinese medicine-components-target genes-disease. The genes in the network are used to construct a protein interaction network to find core genes for analysis of GO and KEGG. Results:There were a total of 84 active ingredients in Chinese medicine Poria and Poria cocos, and 17 effective ingredients and 180 genetic targets were obtained after screening. 600 disease targets for gouty arthritis were identified, and 58 were common target genes for both. PPI network analysis revealed that IL1β, VEGFA, MAPK1, IL10, and PTGS2 may be drugs for treating gouty arthritis. Key targets. GO enrichment analysis identified 1,399 entries (P <0.05), of which biological processes mainly include biological stimulation, biological regulation, cell metabolism, etc; KEGG pathway enrichment analysis identified 152 signal pathways, of which signal pathways involved inflammation, metabolism, In terms of aging, mainly including the IL-4,IL-10,IL-13,IL-17signal pathway, etc. Conclusion:Bi xie and Tu fuling drugs have anti-inflammatory and immunological effects on gouty arthritis through multiple targets and multiple pathways. The mechanism of lowering uric acid and protecting liver and kidney is not clear. It needs molecular biology research to improve it. The mechanism of the action of the Bi xie and Tu fuling medicine pair provides new ideas for the clinical prescriptions.
