Abstract:Objective To explore the mechanism of action of Shenyuan Granules in treating diabetic nephropathy based on network pharmacology. Methods Through the traditional Chinese medicine systems pharmacology database and analysis platform, the pharmaceutical components and action targets of Shenyuan Granules were collected. Target genes of diabetic nephropathy were collected from GeneCards, OMIM, PharmGKB, TTD, and DrugBank databases, and the intersection of drug and disease targets was taken to obtain the intersection target of the prescription for treating diabetic nephropathy. Cytoscape 3.7.2 software was used to construct the Shenyuan Granules composition-intersection target-disease network. The STRING database was used to analyze the intersection targets and construct the protein interaction network. The CytoNCA topological properties were used to construct the topological map of key target proteins, and the intersection gene targets and compounds were ranked according to the nodal degree and intermediate centrality. GO biological processes and KEGG metabolic pathways of key targets were analyzed by R language. Results Thirty-five compounds were selected and 292 predicted targets of Shenyuan Granules were obtained. The number of intersection targets between drugs and diabetic nephropathy was 67. The intersection proteins were uploaded to the STRING database and 55 intersection proteins were obtained. The topology of key targets showed that the first three compounds were quercetin, 7-O-methylisopeugenol and kaempferol. Key targets were protein kinase B, vascular endothelial growth factor A and epidermal growth factor receptor. GO enrichment analysis showed that it mainly involved biological processes such as G-protein-coupled receptors, cellular components such as presynaptic membrane and postsynaptic membrane, and molecular functions such as G protein-coupled amine receptor activity. The enrichment analysis of KEGG metabolism pathway showed that it was mainly involved in stimulating neural tissue action pathway and so on. Conclusion The rationality of the prescription of Shenyuan Granules and the scientificity of the treatment of diabetic nephropathy are preliminarily verified, and the theoretical foundation is laid for the in-depth study of the mechanism of treating diabetic nephropathy with Shenyuan Granules.
