Abstract:
Objective:To study the potential mechanism of Ganwei Baihe Decoction in the treatment of gastric ulcer (GU) based on bioinformatics and validate it through animal experiments.Methods:TCMSP, DisGeNET, and GeneCards databases were used to retrieved active components and action targets of Ganwei Baihe Decoction. After obtaining the intersection, protein interaction data of the intersection genes were obtained through the STRING database. A PPI network was constructed by Cytoscape 3.10.0 software and the key genes and key components were obtained. DAVID online analysis database was used for GO functional enrichment and KEGG pathway enrichment analysis of key targets. Animal experiments were used for verification. Totally 36 SD rats were divided into blank group, model group, Omeprazole group and Ganwei Baihe Decoction group according to the random number table method, with 9 rats in each group. After 7 days of gavage of the corresponding drugs to each group of rats, they fasted and but with water for 24 hours, and then re-gavaged once. After 1 hour of administration, a gastric ulcer rat model was prepared by gavage of 80 mg/kg of indomethacin. After 3 hours of administration, anesthesia was used to extract the sample. The expression level of Caspase-3 protein in the gastric tissue of rats was to be determined by Western blot method.Results:There were 234 effective active components with 290 targets in Ganwei Baihe Decoction, and 6 496 therapeutic targets for GU. 213 potential targets for GU were screened out. There were 437 GO function and 153 KEGG pathway enriched entries. Compared with the model group, the protein expression of Caspase-3 in the Ganwei Baihe Decoction group and Omeprazole group decreased ( P<0.05). Conclusion:The mechanism of Ganwei Baihe Decoction in treating GU may be through key components such as quercetin and β-sitosterol acting on key targets such as AKT1 and CASP3, regulating the Apoptosis pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, etc. to exert inhibitory effects on apoptosis.
