The main objective of this research is to investigate the effects of astragaloside IV, calycosin separately glucoside, formononetin on oxidative stress in Chang Liver cells induced by H2O2. In the experiments, Chang Liver cells (a kind of normal human hepatocytes) were used as the research object, bifendate which has a clear hepatoprotective effect was used as the positive control drug, then the oxidative damage model of Chang Liver cells were established by H2O2. Cells were divided into six groups: blank control group, oxidative stress group, astragaloside IV group, calycosin separately glucoside group, formononetin group and positive control group. Then endogenous antioxidant system related indexes were detected by micro plate and colorimetric method; intracellular reactive oxygen species (ROS) were detected by DCFH-DA fluorescent probe; and the expressions of CYP2E1 were evaluated by liver microsomes, mRNA, and protein, respectively with spectrophotometry, Real-time PCR method, and Western blot technique. Results showed that H2O2 decreased antioxidant activity, and increased ROS level and expression of CYP2E1. The above oxidative stress status had been changed with protections of the three components of Astragalus membranaceus (compared with oxidative stress group, P < 0.05, P < 0.01), which taken as a whole had equivalent effects as the drug of positive control group( bifendate). Taken together, three Astragalus membranaceus ingredients all had significant or extremely significant inhibiting effects on oxidative damaged Chang Liver cells which were induced by H2O2, and the oxidative damage of Chang Liver cells had been relieved.

Objective To explore the effects of amisulpride on the cognitive function in first-episode schizophrenia patients.Methods 64 patients in first-episode schizophrenia were divided into two groups randomly according to the method of tossing a coin,then treated with amisulpride or risperidone respectively for 12 weeks.The efficacy and adverse effect were evaluated with positive and negative scale (PANSS) and treatment emergent side effect scale (TESS) before treatment and after treatment for 2 weeks,4 weeks,8 weeks,12 weeks.Before and after treatment for 12 weeks,cognitive function of all the patients was blindly evaluated with Wechsler Scale-revised China (WMS-RC),Wisconsin Card Sorting Test(WCST) and Trail Making test A and B.Results After 12-week treatment,statistical difference was found in amisulpride(44.7 ± 6.7) and risperidone (45.2 ± 7.4) groups (P < 0.01).But no statistical difference was found between the two groups (P > 0.05).The cognitive function in firstepisode schizophrenia was damaged obviously.In two groups,the scores in recognize,association,comprehend,back a few and MQ of WMS and TAT-A,TAT-B were improved significantly after treatment for 12 weeks (P > 0.05).These items of WCST were improved more remarkably than baseline (amisulpride (20.63 ± 13.06),(28.75 ± 15.72),(43.17 ±22.13),(3.62 ±2.21),P<0.05; risperidone(20.41 ±13.82),(29.31 ± 16.12),(42.78 ± 21.42),(3.67 ± 2.32),P < 0.05).The improvement in the scores of WCST were statistical difference compared with control group(P < 0.05).But statistical difference was no found between the two groups (P > 0.05).Conclusion The study shows that the cognitive dysfunction in first-episode schizophrenia can be improved by amisulpride,and the efficacy was similar with risperidone.

Objective To determine the efficacy of retrovirus-mediated HSV-TK gene transfer and GCV in a BALB/c mice model with urinary bladder transitional cell carcinoma. Methods A replication defective retroviral vector containing HSV-TK gene was used. In vivo experimental animals were divided into 3 groups.In group A,7 tumors were induced in BALB/c mice by subcutaneous injection of MBT-2 transitional cell carcinoma (TCC);the virus was directly injected into the tumor and the animals received intraperitoneal GCV.In group B, 6 tumors were induced in BALB/c mice by subcutaneous injection of transferred HSV-TK gene TCC and the animals received intraperitoneal GCV.In group C,6 tumors were induced in BALB/c mice by subcutaneous injection of MBT-2 TCC and the animals received intraperitoneal normal saline.Tumor-volume measurement was performed in these 3 groups 10 d and 20 d after treatment, and the volume changes were compared among the 3 groups. Results In vivo experiment indicated that the mean tumor volume of group A [MBT-2 group, (55.37?4.52) mm3] and group B [MBT-2/HSV-TK group,(49.77?4.15)mm3] was reduced significantly compared with that of group C [control group,(146.27?10.46)mm3](P0.05).At 20 d after treatment, the mean tumor volume of group A [(186.75?8.14)mm3] and group B [(72.50?6.70)mm3] was also reduced compared with that of group C [(441.76?41.80)mm3] (P

Objective To investigate the expression and function of SH2 domain containing protein tyrosine phosphatase SHP 2 of thymocytes in ? ray irradiation induced leukemia in mice. Methods BALB/c mice were divided into canceration group, non canceration group, and control group. The expression, level of tyrosine phosphorylation, and enzyme catalytic activity of SHP 2 in thymocytes were detected by Western blotting, immunoprecipitation, and biochemical method. Results There was obvious correlation among the expression, level of tyrosine phosphorylation, and enzyme catalytic activity of SHP 2, which were significantly higher in the canceration group than those in the non canceration group and the control group ( P

AIM: To explore the effects of kaempferol on the proliferation, invasion and migration abilities of HBx-HepG2 cells and to examine the underlying molecular mechanisms.METHODS: The expression levels of related genes at mRNA and protein levels were determined by RT-qPCR and Western blot.The cell apoptotic rate was analyzed by flow cytometry.The cell proliferation, growth, invasion and migration abilities were measured by MTT assay, colony formation assay, Transwell invasion assay and wound healing assay, respectively.RESULTS: Kaemferol inhibited HBx-HepG2 cell proliferation in a concentration-and time-dependent manner.Kaempferol at 100 μmol/L significantly inhibited the colony formation, invasion and migration abilities of the HBx-HepG2 cells.Kaemferol at 100 μmol/L also increased cell apoptotic rate, increased the protein levels of cleaved caspase-3, cleaved caspase-9 and Bax, and decreased the expression level of Bcl-2.In addition, kaemferol at 100 μmol/L suppressed the mRNA and protein expression levels of β-catenin, c-Myc and cyclin D1 in the HBx-HepG2 cells.Kaemferol at 100 μmol/L also suppressed the protein level of p-GSK-3β and the β-catenin protein levels in both cytoplasm and nucleus.LiCl treatment reversed the inhibitory effect of kaempferol on the growth, invasion and migration of the HBx-HepG2 cells.CONCLUSION: Kaempferol inhibits cell proliferation, invasion and migration via activating Wnt/β-catenin signaling in HBx-HepG2 cells.
