The effects and mechanisms about Shengjiang powder in improving MNNG-induced gastric mucosal injury
Aim To determine the effects of Shengjiang Powder on gastric mucosal injury and ex-plore its mechanisms.Methods A bibliometric study was conducted to understand the current research status of Shengjiang Powder.The main pharmacological com-ponents of Shengjiang Powder were obtained using liq-uid chromatography-mass spectrometry(LC-MS),and mechanisms were predicted through network pharma-cology analysis.Sprague-Dawley Rats with gastric mu-cosal injury were treated with Vatacoenayme and differ-ent doses of Shengjiang Powder by intragastric adminis-tration.Gastric tissues were collected and stained with HE to observe morphological changes.ELISA was used to detect the levels of TNF-α and IL-1β in serum.IHC was used to evaluate the expression of MUC5AC and MUC6 in the gastric mucosa.Results Bibliometric a-nalysis indicated that Shengjiang Powder is widely used in the treatment of various internal and external inju-ries.LC-MS identified the top 20 compounds as the main pharmacological components of Shengjiang Pow-der,yielding 525 target compounds,of which 129 o-verlapped with gastritis-related targets.GO analysis i-dentified 2,127 entries,and KEGG analysis identified 140 pathways,suggesting that Shengjiang Powder might improve gastric mucosal injury through multiple targets and pathways.HE staining results demonstrated that Shengjiang Powder could significantly improve gas-tric mucosal inflammation in rats.ELISA results showed that Shengjiang Powder effectively reduced the levels of TNF-α and IL-1 β in rat serum.IHC results indicated that Shengjiang Powder effectively downregu-lated MUC5AC expression and upregulated MUC6 ex-pression.Conclusion Shengjiang Powder can im-prove gastric mucosal injury by alleviating inflammation and regulating the surface mucus barrier.
