Objective:To treat the chronic non-atrophic gastritis patients induced by Helicobacter pylori with Qingweizhitong Weiwan combined with standard triple therapy,and to detect the differential expression of related immflammation genes with PCR array,and to clarify its mechanism.Methods: Ten patients with chronic non-atrophic gastritis complicated with Helicobacter pylori infection were used as treatment group and 10 health people were used as health control group. The patients in treatment group were treated with Qingweizhitong Weiwan combined with standard triple therapy for 14 d. The blood samples of the subjects in treatment group and health control group were collected before and after treatment,and QIAGEN human antibacterial response PCR array was performed to test the total RNA inperipheral blood and to analyze the differential expressions of 84 inflammation-related genes.Results:The differential expressions of 20 inflammation-related genes were found.Compared with health control group,the expression levels of 20 genes in treatment group before treatment were up-regulated (Fold-change>2);after treatment,the expression levels of 20 genes were down-regulated,and 11 of them were similar to the level in health control group (Fold-change< 2).More specifically,part of 20 genes was related to NLRP3 inflammasome.Compared with health control group,the gene expression levels of CASP1,IL1B,NLRP3,and PYCARD in treatment group before treatment were up-regulated (P <0.05).Compared with before treatment,the expression levels of CASP1,IL1B,NLRP3,and PYCARD in treatment group after treatment were down-regulated (P <0.05).Conclusion:The mechanism of Qingweizhitong Weiwan combined with standard triple therapy in the treatment of chronic non-atrophic gastritis patients induced by Helicobacter pylori may be related to inhibiting the expressions of NLRP3 inflammasome-related genes and interfering the antimicrobial innate immune response.

OBJECTIVETo analyze the clinical features and potential mutations of the SLC25A13 gene in a boy affected with neonatal intrahepatic cholestasis.
METHODSClinical data and peripheral venous blood sample of the child, and peripheral venous blood samples of both parents, were collected. All coding exons of the SLC25A13 gene were amplified with PCR and subjected to direct DNA sequencing.
RESULTSThe boy was found to be a compound heterozygote carrying c.851_854delGTAT and IVS16ins3kb mutations of the SLC25A13 gene, which were respectively inherited from his mother and father.
CONCLUSIONBased on its clinical and genetic features, the patient was diagnosed with neonatal intrahepatic cholestasis caused by citrin deficiency.

OBJECTIVE: To study the effects of ivermectin on the migration and invasion of human gastric cancer cell lines BGC-823 and MGC-803 and its mechanism. METHODS: After treated with 0, 2.5, 5, 10, 20, 40 μmol/L ivermectin for 24 h, inhibitory rate of human gastric cancer cell lines BGC-823 and MGC-803 were detected by MTT assay. Effects of 5 μmol/L ivermectin and phosphate buffercontaining 0.67‰ dimethyl sulfoxide (control group) for 24 h on the migration and invasion of` gastric cancer cells BGC-823 and MGC-803 were observed by Transwell chamber invasion assay.Western blot assay was used to detect the protein expression of TGF-β1, TGF-βR, Smad2 and Smad3 in epithelial-mesenchymal transition (EMT) markers E-cadherin, N-cadherin, Vimentin, Snail and EMT transduction pathway TGF-β/smad of BGC-823 and MGC-803 cells after treated with 5, 10 μmol/L ivermectin and phosphate buffercontaining 0.67‰ dimethyl sulfoxide (control group) for 24 h. RESULTS: Ivermectin could inhibit the growth of BGC-823 and MGC-803, inhibitory rate of it was positively correlated with its concentration. Compared with control group, the number of migration and invasion BGC-823 and MGC-803 cells were decreased significantly after treated with 5 μmol/L ivermectin (P<0.01 or P<0.001); the expression of E-cadherin protein was enhanced significantly in BGC-823 and MGC-803 cells after treated with 5 and 10 μmol/L ivermectin (P<0.05 or P<0.01 or P<0.001); the protein expression of N-cadherin, Vimentin, Snail, TGF-βR, Smad2 and Smad3 were decreased significantly (P<0.05, P<0.01 or P<0.001); protein expression of TGF-β1 was decreased significantly after treated with 10 μmol/L ivermectin (P<0.05). CONCLUSIONS: Ivermectin can significantly inhibit the migration and invasion of gastric cancer cells BGC-823 and MGC-803, and inhibiting the biological activity of EMT by reducing the expression of TGF-β/smad pathway is one of the mechanisms that inhibit the migration and invasion of gastric cancer cells.
