Objective To evaluate the relationship between interleukin-18(IL-18) and insulin resistance, measured by euglycemic hyperinsulinemic clamp, in women with polycystic ovary syndrome (PCOS). Methods Forty-two young women with PCOS and 38 age-and body mass index (BMI)- matched control women were recruited in this study. A complete hormonal assay was performed and serum IL-18 level was determined in each subject. And euglycemic hyperinsulinemic clamp test was completed in 41 of the above subjects. Results Serum IL-18 levels were increased in the PCOS women, as compared with the control (P=0.033). When all subjects were divided into lean and obese groups, the IL-18 levels were slightly increased in the obese subjects (P=0.902). IL-18 levels were negatively correlated with all the clamp parameters [mean glucose infusion rate (M), M-to-insulin ratio (M/I) and glucose metabolic clearance rate (MCRg), r =-0.419,-0.396,and-0.405,P=0.006,0.010 and 0.009 respectively], but were positively associated with HOMA-β index(r=0.334, P=O.035). Conclusion Serum IL-18 level was significantly increased in PCOS women and was strongly associated with the parameters obtained from the euglycemic hyperinsulinemic clamp, indicating that IL-18 may be an important mediator between inflammation and insulin resistance.

The aim of the manuscript was to optimize formulations and preparation technologies of cataplasm of white mustard seed varnish, and to evaluate its anti-asthma effect on rats. The single factor experiments included spreading thickness, types of crosslinking agents, dihydroxyaluminum aminoacetate amount, sodium polyacrylate amount, types of adhesive agents with human sense as the evaluation index. Blank cataplasm matrix was optimized by the orthogonal experiment with the amount of glycerine, citric acid, and sodium carboxymethylcellulose as the major influential factors. Initial adhesive force, peeling strength and human sense were as the evaluation index. The optimized formulation of blank cataplasm were as followings: glycerine-water-ethanol-PEG400-dihydroxyaluminum aminoacetate-citric acid-sodium carboxymethylcellulose-sodium carboxymethylcellulose 2 : 8 : 0.8 : 0.4 : 0.07: 0.15 : 0.1 : 0.5. The active ingredients of white mustard seed, corydalis, and gansui root were extracted by alcohol extraction method. Asiasarum volatile oil was extracted by oil extractor. The optimized drug loading amount was 11% with initial adhesive force, peeling strength and human sense as the evaluation index. Asthma rats model were established by sensitized with ovalbumin and nose-scratching time as the evaluation index. High dose (17%) group of drug-loaded cataplasm had the obvious inhibition effect on nose-scratching time of rats (P = 0.037 < 0.05). In comparison, middle dose (11%), low dose (4%) and positive-control groups had no obvious inhibitive effect on rats. White mustard seed cataplasm supplied a novel choice for anti-asthma therapy. And the overall pharmacodynamics assessment will be carried out on molecular level in near future.

OBJECTIVETo study the effects of extracts of ginkgo biloba (EGB) on the levels of nitric oxide (NO) and apoptosis in the retina induced by glutamate by intravitreal injection in adult rabbit.
METHODThe model of apoptosis in retina induced by glutamate by intravitreal injection was established in adult rabbit and EGB was retrobulbarly injected. The levels of NO were measured by spectrophotometer. Retina DNA fragmentation was determined by agarose gel electrophoresis.
RESULTThe levels of NO in retina in experiment groups were significantly increased compared with controls, after treatment with high dosage of EGB, and levels of NO was decreased to normal. They were not decreased by injection of small dosage of EGB. DNA fragmentation of retina apoptosis was detected in experiment groups and small dosage EGB groups.
CONCLUSIONThe retina apoptosis was induced by glutamate by intravitreal injection in adult rabbit and was inhibited by EGB that may be through blocking the generation of NO free radicals.
