Objective To explore the mechanism of Yiyi Fuzi Powder in treating rheumatoid arthritis (RA) and chronic heart failure (CHF) based on network pharmacology and molecular docking method. Methods The active components of Yiyi Fuzi Powder were screened by TCMSP database, and Smile number was obtained by Pubchem database, then the targets were obtained by Swiss TargetPrediction Database. The disease targets were predicted by GeneCards and OMIM database. Protein-protein interaction (PPI) network was constructed and core targets were screened, and GO function and KEGG enrichment were analyzed. After screening the core components and core targets, AutoDock software was used for molecular docking verification. Results A total of 10 compatible active components were screened, 403 potential drug targets, 1 112 targets for RA, 2 983 targets for CHF, and 69 drug-disease intersection targets were screened after the intersection. The results of GO enrichment analysis showed that it was mainly related to the regulation of inflammatory response, MAPK cascade regulation, response to oxidative stress, regulation of ossification, smooth muscle cell proliferation, etc. The enrichment analysis of KEGG pathway obtained 236 pathways. The pathways related to RA and CHF and ranked higher are PI3K-Akt signal pathway and NF-κB signal path, MAPK signal path, etc. The results of molecular docking showed that the core components of Yiyi Fuzi Powder, such as karakoline, karanjin, stigmasterol, had good binding potential with target genes TNF, SRC, ESR1 and PTGS2. Conclusion Yiyi Fuzi Powder has a multiple target effect in the treatment of RA and CHF, involving multiple biological processes and signal pathways, which may play the role of "treating different diseases with the same therapy" by regulating inflammatory response, oxidative stress response, angiogenesis and development, cardiac contraction regulation and MAPK cascade regulation.
