Abstract:

Objective: To explore the underlying molecular mechanism of Tounong San in abscess-type lymph node tuberculosis treatment using network pharmacology. Methods: The active components and potential target of Tounong San were searched and screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). These genes were mapped with the abscess-type lymph node tuberculosis related genes obtained by Genecards and OMIM database, thereby obtaining inter section targets. The String 11.5 database and Cytoscape 3.9.1 software were used to construct the protein-protein interaction (PPI) network and the active ingredient-core target network. Then, gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis of core target genes were carried out by using DAVlD 6.8 platform. Using the DAVID database, we performed intersection target gene ontology functional enrichment analysis and signaling pathway enrichment analysis of the Kyoto gene and genome database. Results: A total of 72 effective drug targets were screened out. Enrichment analysis indicated that the signaling pathways involved in Tounong San in abscess-type lymph node tuberculosis treatment were cell apoptosis and oxidative stress response signaling pathways. AKT1, TP53, ALB and CASP3 might be the key genes in Tounong San-mediated abscess-type lymph node tuberculosis treatment. Conclusion: Tounong San may influence AKT1, TP53, ALB and CASP3 gene expression, to achieve the purpose of treating abscess-type lymph node tuberculosis.
