After enlarging student's enrollment in college,the great change of education and teaching situation took place.In order to improve the teaching quality in medical college,some problems in experiment teaching and their countermeasures were put forward in this paper,such as the experimental kinds and methods of experiment,the arrangement of experiment classes,the fitting out and the use of equipment as well as the modern education techniques and experiment education,etc.

Objective To evaluate the difference of carotid intimal medial thickness (IMT) among different glucose tolerance status and to investigate the association of IMT with different glucose levels of 4 time points during oral glucose tolerance test (OGTT) and the lipid metabolic indices in non-diabetic subjects. Methods Eleven normal control subjects, 69 subjects with impaired glucose regulation (IGR) newly diagnosed by OGTT (including 28 patients with non-elevated OGTT 30 min and 60 min glucose values (

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.

Objective To study insulin sensitivity and first-phase insulin secretion in obese subjects with impaired glucose regulation (ICR) in Shanghai. Methods A total of 129 subjects [38 lean controls and 91 obese subjects with ICR including 64 isolated impaired glucose tolerance (IGT) ,8 isolated impaired fasting glucose (IFC) and 19 IFC + ICT] underwent 75 g oral glucose tolerance test and insulin-modified reduced sample number (n = 12) of Bergman's minimal model method with frequently sampled intravenous glucose tolerance test (FSIGTT). Insulin resistance was determined from the insulin sensitivity index (S1) of the FSIGTT. Insulin secretion was determined during the FSIGTT by the acute insulin response to glucose (AIRg). The disposition index (DI) , the product of AIRg and S1, was used to determine whether AIRg was adequate to compensate for insulin resistance. Results (1) Compared with normal controls, the value of S1 was significantly decreased in 3 groups with ICR (all P

Based on the reported inhibitors TH287, 17 five-membered heterocyclopyrimidine derivatives were designed and synthesized by cyclization, scaffold hopping, bioisosterism and molecular docking technology. The bioassays determined by malachite green method demonstrated that the target compounds displayed good inhibitory activity against MTH1. Among them, the IC50 value of 7 compounds was less than 1 μmol/L, suggesting that these compounds may be candidates for further investigation.
