Systematic Review and Meta-analysis of Efficacy of Banxia Xiexin Decoction for Treatment of Bile Reflux Gastritis

[Objectives]The purpose was to study the clinical efficacy and safety of Banxia Xiexin decoction in treating bile reflux gastritis(BRG).[Methods]Randomized controlled trial was adopted to conduct scientific and standardized assessment on the risk of bias in the included articles.With overall effect and epigastric pain relief as indices,meta-analysis was performed,and sensitivity and safety analysis was conducted on the included literature.[Results]A total of 13 articles were included,involving a total of 1478 patients.The results of meta-analysis show that the efficacy of Banxia Xiexin decoction alone and Banxia Xiexin decoction-Western medicine combination is better than that of Western medicine alone.[Conclusions]Banxia Xiexin decoction is safe and effective in treating bile reflux gastritis.However,as the 13 articles included are all low in quality and there is a certain degree of publication bias,the objectivity of the results is affected to some extent.

Diagnostic value of confocal laser endomicroscopy in primary bile reflux gastritis

Objective To evaluate the accuracy of confocal laser endomicroscopy(CLE)in primary bile reflux gastritis(BRG).Methods From November 10 to December 15,2015,55 patients undergoing CLE examination and preliminarily diagnosed as BRG with traditional white-light endoscopy were enrolled.CLE score standard was designed.Dixon pathologic score was considered as

Deciphering the chemical profile and pharmacological mechanism of Jinlingzi powder(金铃子散)against bile reflux gastritis using ultra-high performance liquid chromatography coupled with Q exactive focus mass spectrometry,network pharmacology,and molecular docking

OBJECTIVE:To elucidate the chemical profile and the pharmacological mechanism by which Jinlingzi powder(金铃子散,JLZP)treats bile reflux gastritis(BRG).METHODS:A BRG model was established in rats by oral administration of the model solution.JLZP was orally administered for 35 d.Residual gastric rate and tumor necrosis factor(TNF)-α,interleukin(IL)-6,and gastrin levels in the serum were measured,and stomach tissues were collected for histopathological analysis.We used ultra-high performance liquid chromatography coupled with Q Exactive Focus mass spectrometry to identify the chemical ingredients in JLZP.Then,protein-protein interaction and herb-compound-target networks were constructed to screen potential bioactive compounds and targets.Kyoto Encyclopedia of Genes and Genomes pathway analysis was then performed to elucidate the pathway involved in the JLZP-mediated treatment of BRG.After constructing the core compound-target-pathway interaction network,molecular docking was performed to study the binding free energy of core bioactive compounds and two candidate targets[RAC-alpha serine/threonine-protein kinase(AKT1)and phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform(PIK3CA)].RESULTS:JLZP extracts significantly promoted gastric emptying,regulating the release of cytokines(TNF-αand IL-6)and improving gastrin secretion and mucosal repair.Fifty-six compounds were tentatively characterized in JLZP.Moreover,the network pharmacology and molecular docking results showed that alkaloids and flavonoids might be the bioactive compounds in JLZP that treat BRG.JLZP might improve mucosal repair during BRG progression by modulating the phosphatidylinositol-4,5-bisphosphate 3-kinase-protein kinase B,hypoxia inducible factor-1,mitogen-activated protein kinase,forkhead box O,TNF,and IL-17 signaling pathways.CONCLUSIONS:We elucidated the chemical constituents and the pharmacological mechanism of JLZP in treating BRG and provided a basis for clinical application.
