Objective To investigate the impact of chronic observational social defeat stress on multidimensional behaviors in female mice,including social interaction,emotion,and cognition,as well as the underlying molecular mechanisms.Methods Adult female C57BL6N mice were divided into a stress group and a control group.Behavioral assessment were conducted through social interaction tests,anxiety-like behavior tests,and cognitive tests(novel object recognition and spatial memory).Synaptic plasticity-related proteins in the hippocampus were detected using Western blot.Results Behavioral tests revealed that the stress group showed reduced social interaction time compared to the control group[(106.2±9.31)s vs.(156.5±14.81)s,P<0.05].In a novel environment,the stress group consumed less food than the control group[(0.10±0.01)g vs.(0.16±0.02)g,P<0.05].Cognitive tests demonstrated that the stress group exhibited impaired novel object recognition[(52.17%%±2.67%)vs.(65.91%±5.23%)]and spatial memory[(61.84%±3.14%)vs.(74.13%±1.94%)]compared to the control group(P<0.05).Western blot analysis showed that the expression of hippocampal synaptic plasticity-related proteins,including the glutamate ionotropic receptor N-methyl-D-aspartate(NMDA)receptor subunit NR2A[(0.66±0.05)vs.(0.89±0.08)]and brain-derived neurotrophic factor(BDNF)[(0.81±0.05)vs.(1.14±0.06)],was significantly decreased in the stress group(P<0.05).Conclusion Chronic observational social defeat stress induces social withdrawal,anxiety-like behaviors,and cognitive deficits in female mice.These effects may be associated with reduced expression of NR2A and BDNF in the hippocampus.

Objective To evaluate clinical effect of Compound Fanshiliu Recipe(CFR) for the treatment of over-weighted type 2 diabetes mellitus(T2DM). Methods One hundred and twenty over-weighted T2DM patients were randomized into treatment group and control group, 60 cases in each group. Both groups were given oral use of Metformin Hydrochloride Enteric-Coated Tablets, and additionally the treatment group was treated with CFR orally. The treatment of both groups lasted for 12 continuous weeks. Before and after treatment, we detected the waist circumference (WC), body mass index (BMI), and the levels of fasting blood glucose(FBG), postprandial 2-hour blood glucose(P2hBG), glycosylated hemoglobin(HbA1c), total cholesterol(TC), triglyceride (TG), and free fatty acid (FFA). The therapeutic effect of the two groups was also evaluated after treatment. Results (1) The total effective rate for traditional Chinese medical symptoms was 95.00% in the treatment group, and was 70.00%in the control group, the difference being significant(P<0.01).(2) After treatment, WC and BMI were decreased in the treatment group(P<0.01 compared with those before treatment), but had no significant decrease in the control group(P>0.05). The decrease of WC and BMI of the treatment group was superior to that of the control group(P<0.05).(3) After treatment, levels of FBG, P2hBG, HbA1c, TC, TG, and FFA of both groups were significantly improved (P<0.05), and the improvement of the treatment group was superior to that of the control group(P<0.05).(4) Three patients of the treatment group suffered from slight gastric discomfort, and the discomfort was relieved without any special treatment. Other patients of the two groups had no adverse reaction. Conclusion Treatment of CFR combined with Metformin has been proved to be an effective and safe approach to decrease blood glucose and blood lipid levels, promote weight loss, and ameliorate traditional Chinese medical symptoms.

Objective To investigate the therapeutic effect of topiramate on diabetic peripheral neuropathy.MethodsEighty three patients with diabetic peripheral neuropathy were randomly divided into the control group (n=40) and treatment group (n=43). All patients of two groups were given antidiabetic drugs and vitamine B treatment. While the treatment group was added with topiramate orally for 1 month.ResultsThe total effective rate of the treatment group and control group were 90.7% and 67.5% respectively with a significant difference between two groups ( P<0.05). The velocity of sensory and motor conduction of all patients obviously increased after one month treatment, but the nerve conductive velocity of the patients in the treatment group was significantly higher than that in the control group ( P<0.001).ConclusionOn the basis of lowing blood glucose, using topiramate is more effective on diabetic peripheral neurophy and without obvious side effect.
