Mechanisms of the role of fibroblast growth factor 21 in attenuating insulin resistance / 药学学报

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on type 2 diabetic mice model and to provide mechanistic insights into its therapeutic effect. Type 2 diabetic animal model was established with high calorie fat diet and low dose streptozotocin (STZ) injection. Mice were then randomized into 5 groups: model control, FGF21 0.25 and 0.05 μmol x kg(-1) x d(-1) groups, insulin treatment group. Ten age-matched normal KM mouse administered with saline were used as normal controls. Serum glucose, insulin, lipid products and the change of serum and liver tissue inflammation factor levels between five groups of mouse were determined. The results showed that blood glucose, insulin, free fatty acids (FFAs), triglycerides, and inflammatory factor average FGF-21 of type 2 diabetes model group and normal control group were significantly higher (P < 0.01), while compared with insulin group, no difference was significant. Average blood glucose, insulin, blood lipid and inflammatory factor of FGF-21 treatment group compared with type 2 diabetes group was significantly lower (P < 0.01) and insulin group has no difference with the model control group. The results of OGTT and HOMA-IR showed that insulin resistance state was significantly relieved in a dose-dependent manner. Thus, this study demonstrates that FGF-21 significantly remits type 2 diabetic mice model's insulin resistance state and participates in the regulation of inflammatory factor levels and type 2 diabetes metabolic disorders.

Efficacy of alfentanil and remifentanil in minimizing propofol injection pain / 上海第二医科大学学报

Objective To compare the efficacy of alfentanil and remifentanil in minimizing the propofol injection pain. Methods A total of 175 adult female patients undergoing gynecological procedures with general anesthesia were randomly divided into four groups.Patients received alfentanil 1mg(2 mL,AL group,n=43),remifentanil 0.01 mg(2 mL,REM1 group,n=43),remifentanil 0.02 mg(2 mL,REM2 group,n=45) or normal saline(2 mL,control group,n=44) 30 seconds prior to propofol administration.Visual analogue scale(VAS) was employed to evaluate the subjective feelings of pain due to propofol injection,and adverse effects were recorded. Results One patient in REM2 group and one patient in control group were excluded due to difficulty in venous catheterization.The injection pain in AL group,REM1 group and REM2 group was significantly less severe than that in control group(P
