Mechanism of therapeutic effects of Huangbo on ureteral stones based on network pharmacology

Objective:To analyze the effective chemical components and action targets of Phellodendron chinense,and to study the mechanism of Phellodendron chinense in treating ureteral stones.Methods:Search the potential chemical active substances of Phellodendron chinense and target proteins acting on the human body through the TCMSP database,and use the genomic annotation database platform(Genecards)to predict the target of ureteral stones,and use the uniprot database Query the corresponding gene names,build a network diagram of"drug-disease-target"with the help of Cytoscape(3.7.2)software,build a protein interaction network through the String database platform,and then use the Bioconductor platform and R language GO Enrichment analysis and KEGG enrichment analysis.Results:Through screening,a total of 36 effective chemical constituents of Phellodendron chinense,8 key chemical constituents related to ureteral calculi,and 20 common targets of Phellodendron-ureteral calculi were obtained.The core genes of PPI were FOS,CXCL8,IL6,SERPINE1,VEGFA,EGF,NOS3,SPP1,CCL2,CCND1,EGFR,HMOX1,IL10,CDKN1A,CRP;obtained 36 GO biological processes,and 14 KEGG related signaling pathways,including HIF-1 signaling pathway,FoxO signaling pathway,EGFR tyrosine kinase inhibitor resistance,endocrine resistance,viral protein interaction with cytokines and cytokine receptors,calcium signaling pathway,p53 signaling pathway,ErbB signaling pathway,MAPK signaling pathway,Ras signaling pathway.Conclusion:Phellodendron can achieve the effect of treating ureteral calculi through multiple targets and multiple ways,which provides a theoretical basis for the future extraction of effective components to treat ureteral calculi.
