Objective To investigate the effect and mechanism of DADS in inhibiting the proliferation and inducing apoptosis of gastro-esophageal cancer cells in vitro.Methods The gastro-esophageal adenocarcinoma cells OE1 9 were treated by DADS of different concentrations in vitro.Morphologic changes were observed by the microscope and MTT assay was performed to test the growth-inhibitory effect of DADS on OE1 9 cells.Apoptosis rate of OE1 9 treated with different concentrations of DADS was measured by flow cytometry.Real-time PCR was used to detect DADS-induced effects on mRNA expressions of Caspase-3 ,Caspase-9 ,Bcl-2 ,Bax and NF-κB in OE1 9 cells.Results DADS inhibited the proliferation of OE19 cells in a dose-dependent manner.The apoptosis rate of OE19 cells was 14.0%,25.4% and 19.0% and 27.2%,respectively,when treated with 40 and 80μg/mL DADS for 24 h and 48 h.Real-time PCR assay showed that DADS could enhance mRNA expression levels of Caspase-3 and Caspase-9 and significantly decrease the mRNA expression levels of NF-κB and Bcl-2 and the ratio of Bcl-2/Bax. Conclusion DADS can significantly inhibit the proliferation and induce the apoptosis of gastro-esophageal adenocarcinoma cells via mitochondria-dependent pathways,which may be related to NF-κB and Bcl-2 families.

Objective To investigate the efficacy of Jianpiwenyang Gel(SSWYG)for treating chronic diarrhea and explore its therapeutic mechanism.Methods Eighty patients with chronic diarrhea of spleen and stomach weakness type were randomized into two groups for interventions with lifestyle adjustment and treatment with bifid triple viable capsules(control group,n=40)or naval application with SSWYG(treatment group,n=40)for one week,after which symptoms of chronic diarrhea were evaluated.The Chinese medicine system pharmacology analysis platform(TCMSP),GeneCards,NCBI,OMIM database and GEO database(GSE14841)were used to obtain the active ingredients and target proteins of SSWYG and chronic diarrhea-related targets.The key targets were obtained by topological analysis for Gene Ontology(GO)and KEGG analyses.The affinity and binding characteristics of SSWYG for specific targets were verified by molecular docking using AutoDock software.Results In both groups,gastrointestinal symptom rating scale(GSRS),Bristol Scale and TCM syndrome scores significantly improved after the treatments(P<0.05),and better effects were observed in the treatment group(P<0.05).Sixty-eight targets of SSWYG in treating chronic diarrhea were obtained,and 33 most probable ones were screened out by topological analysis.GO and KEGG analyses identified several chronic diarrhea-related pathways including the TNF and IL-17 pathways.Molecular docking study showed good affinity of the core components of SSWYG for the key targets CASP3,JNK,IL1B,IL6,and AKT1.JUN and CASP3 had the lowest binding energy and the highest stable binding energy with multiple major active ingredients of SSWYG.Conclusion SSWYG can significantly improve clinical symptoms of chronic diarrhea possibly by regulating the TNF and IL-17 as well as other pathways via CASP3 and JUN,suggesting a complex therapeutic mechanism of SSWYG involving multiple ingredients and targets and coordinated regulation of multiple pathways.

Background:Functional dyspepsia (FD)with anxiety and gastric hypersensitivity is still one of the therapeutic difficulties in clinic. Gastrodin (Gas)may have dual effects of modulating gastric sensitivity and anxiety. Aims:To investigate the effect of Gas on gastric sensitivity and anxiety-like behavior in FD with anxiety-like gastric hypersensitivity in rats. Methods:Forty rats were randomly divided into control group,model group,buspirone group,low-dose Gas group and high-dose Gas group. Maternal separation,acute gastric irritation and restraint stress were sequentially performed to induce FD model with anxiety-like gastric hypersensitivity. At the 8th week,rats in control group and model group were intraperitoneally injected with 0. 9% NaCl solution 2. 0 mL/ kg,rats in buspirone group were given buspirone 3. 125 mg/kg,and rats in low- and high-dose Gas groups were given 62. 5,125. 0 mg/ kg Gas,respectively. The course was 7 days. Then elevated plus maze (EPM),open field test,abdominal withdrawal reflex (AWR)and electromyography (EMG) were performed. Results:Compared with control group,EPM test showed that proportions of open arms entries and duration were significantly decreased (P < 0. 01);open field test showed that virtual central grids duration (P < 0. 05),number of virtual grids climbed and times of lifting were significantly decreased (P < 0. 01);when gastric balloon dilatation pressure was equal or greater than 40 mm Hg,AWR score,area under ROC curve (AUC)of EMG was significantly increased in model group (P < 0. 05). Compared with model group,above-mentioned indices in low- and high-dose Gas groups were significantly ameliorated (P < 0. 05). Conclusions:Gas could influence the gastric sensitivity and anxiety-like behavior of the brain-stomach axis regulated anxiety-like gastric hypersensitivity in FD rat model.
