Objective:To evaluate the efficacy and safety of amisulpride and risperidone in the treatment of schizophrenia. Meth-ods:The RCTs literatures on amisulpride and risperidone in the treatment of schizophrenia were retrieved and screened, and the quali-fied ones were analyzed by meta-analysis. Results:A total of 10 literatures were included involving 802 patients. Meta-analysis results showed that the difference between the two groups after the treatment was not statistically significant by comparing the clinical efficien-cy, PANSS score and TESS score. About the incidence of adverse reactions, amisulpride was better than risperidone in the endocrine function, extrapyramidal symptoms, weight gain and cardiovascular system. The incidence of nausea and vomiting of amisulpride was more than that of risperidone. There was no statistical significance in insomnia, headache, dizziness and the others. Conclusion:Ex-isting literature analysis shows that amisulpride is safe and effective in the treatment of schizophrenia.

The liver is the central organ involved in lipid metabolism and the gastrointestinal(GI)tract is responsible for nutrient absorption and partitioning.Obesity,dyslipidemia and metabolic disorders are of increasing public health concern worldwide,and novel therapeutics that target both the liver and the GI tract(gut-liver axis)are much needed.In addition to aiding fat digestion,bile acids act as important signaling molecules that regulate lipid,glucose and energy metabolism via activating nuclear receptor,G protein-coupled receptors(GPCRs),Takeda G protein receptor 5(TGR5)and sphingosine-1-phosphate receptor 2(S1PR2).Sphingosine-1-phosphate(S1P)is synthesized by two sphingosine kinase isoforms and is a potent signaling molecule that plays a critical role in various diseases such as fatty liver,in-flammatory bowel disease(IBD)and colorectal cancer.In this review,we will focus on recent findings related to the role of S1P-mediated signaling pathways in the gut-liver axis.

Objective To develop neural stem cells(NSCs) which can stably express exogenous brain-derived neurotrophic factor(BDNF) in vitro. Methods NSCs from the subependymal zone of embry-onic day 14.5(E14.5) rat brain were purified by limiting dilution assay and then infected with supernatant of recombinant retrovirus pLXSN-BDNF and retrovirus pLXSN. The original copy numbers of exogenous gene templates from three groups NSCs(pLXSN-BDNF viral infection group, pLXSN viral infection group, control group) were detected by fluorescent quantitative PCR(FQ-PCR). ELISA assay was used for determining the protein contents of BDNF of supernatant from three groups NSCs for six days continually after seeded in 24-well plates in the same cell density. Results NSCs were purified successfully by limiting dilution assay.The original copy numbers of exogenous BDNF gene templates from pLXSN-BDNF viral infection group by FQ-PCR were (19.57±0.65) × 10~3 copies/μl, higher than those of another two groups(P < 0.05). The protein contents of BDNF of supernatant from NSCs of pLXSN-BDNF viral infection group was highest among three groups and compared with another two groups had statistical significance (P <0.05) . Conclusion The purified NSCs can be transduced exogenous BDNF successfully with supematant of recombinant retrovir-us pLXSN-BDNF which provide experimental evidences and laying foundations for further research of retinal transplantation and quantization investigation of gene therapy for optic nerve injury.
