| Abstract: |
| Objective：To investigate the mechanism of action of Gegen Qinlian decoction as homotherapy for heteropathy in the treatment of periodontitis and ulcerative colitis based on network pharmacology and molecular docking.Methods：TCMSP database was used to obtain the chemical components of Gegen Qinlian decoction and their corresponding action targets，and GeneCards，DisGeNET，and OMIM databases were used to obtain the targets of the two diseases.Bioinformatics plotting tool was used to plot the Venn diagram to obtain the intersecting targets of the action targets of the active components and the targets of the two diseases，so as to obtain the common action targets of the drug and the diseases.Cytoscape 3.9.1 was used to construct a drug-component-target network，and STRING database was used to analyze the common targets.A protein-protein interaction network was constructed，and a visual analysis was performed.DAVID database was used to perform gene ontology functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of the common targets.AutoDock Tools was used to perform molecular docking between the core components of the drug and the key targets.Results：Through the core components including quercetin and beta-sitosterol，Gegen Qinlian decoction exerted anti-oxidative stress and anti-cell apoptosis effects and participated in the regulation of glucose and lipid metabolism by acting on the key targets such as TNF，AKT1，IL-6，IL-1β，and VEGFA，involving the pathways such as the AGE-RAGE signaling pathway and the cancer pathway.Molecular docking showed good binding activity between the core components of the drug and the key targets.Conclusion：Gegen Qinlian decoction，as homotherapy for heteropathy，exerts a therapeutic effect on periodontitis and ulcerative colitis through multiple targets and pathways. |
