Mechanism of Shengjiang Powder in treating chronic tonsillitis in children based on network pharmacology and molecular docking

Based on the network pharmacology and molecular docking method to explore the molecular mechanism of Shengjiang Powder in treating chronic tonsillitis in children. This research first based on the Traditional Chinese Medicine System Pharmacology(TCMSP) and the Bioinformatics Analysis Tools for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM), the effective active ingredients of the drugs contained in Shengjiang Powder were screened out by the pharmacokinetic(ADME) parameters, the targets were predicted, and then chronic tonsillitis disease in children targets were obtained by GeneCards database. Afterwards, the target protein names were standardized by the Uniprot database. The drug targets were matched with the disease targets to obtain the potential therapeutic targets of Shengjiang Powder. Cytoscape 3.8.0 software was used to screen out and construct the network diagram of "drug-components-core targets-disease". DAVID database and R language were used to conduct the enrichment analysis of core action targets. Finally, AutoDock software was used to conduct molecular docking between drug components with a high network medium value and core action targets. According to the findings, after standardized treatment, a total of 79 active ingredients of Shengjiang Powder were obtained;it was predicted to get 1 261 potential targets, 268 potential targets for treatment of chronic tonsillitis in children, and 29 core targets;and 81 entries of GO enrichment were determined(P<0.05), including 63 biological processes, 7 cell components, 11 molecular function items, 24 KEGG pathway enrichment items(P<0.05), mainly including cell cycle, inflammatory factors, viral infection, immune regulation and other signaling pathways. The results of molecular docking showed that main active components in Shengjiang Powder had a stable binding activity with the core targets. This study revealed the mechanism of Shengjiang Powder in the treatment of chronic tonsillitis in children, mainly by resisting virus, inhibiting inflammation, regulating immunity and other means to play a synergistic effect, so as to provide a theoretical basis for rational clinical application.
