Objective To construct a quantizing criterion for evaluation of test paper and to analyze the quality of test papers on examination courses in Guangdong medical college,so as toprovide evidence for quality management of examination.Method The test papers of 97 examination courses from January to June in 2007 in Guangdong medical college were self-checked and checked randomly by expert.Results The score of 97 examination courses self-check was lower than that of inspected randomly by expert,and the superiority rate of self-check courses was higher than that of checked by expert.The mark of the correction of the test paper in self-checked courses was lowest,but the scores of difficulty and analysis and summary of test paper in the courses checked by expert were lower than the other points.The score of public fundamental courses was lower than preclinical medicine courses,clinical medicine and other professional courses.Conclusion A quantizing criterion for evaluation of test paper was constructed which consistent with the circumstance and can be employed for the evaluation of test paper.The quality of majority test paper of examination courses in Guangdong medical college were superior.

AIM: To explore the serum levels of visfatin (VF) and tumor necrosis factor-alpha (TNF-α) in the patients with pre-eclampsia (PE) and their correlation with insulin resistance (IR).METHODS: The severe PE pa-tients (n =30), mild PE patients (n =30) and normal pregnant women (n =40) were selected according to the classifica-tion standard of PE.The serum levels of VF and TNF-αwere measured by ELISA.Fasting plasma glucose (FPG) and fasting insulin (FIns) were detected by glucose oxidase method and radioimmunoassay, respectively.Triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol ( HDL-C) and low-density lipoprotein cholesterol ( LDL-C) were measured by an automatic biochemical analyzer.According to calculating the mean arterial pressure (MAP), body mass index (BMI) and homeostatic model assessment for insulin resistance index (HOMA-IR), the correlation between IR and the levels of serum VF as well as TNF-αwere analyzed.RESULTS: The levels of VF and TNF-αin severe PE group and mild PE group were significantly lower than those in normal pregnancy group (P <0.05).In addition, the levels of VF and TNF-αin severe PE group were lower than those in mild PE group (P <0.05).Linear correlation analysis showed that serum VF was positively correlated with TNF-αand HDL-C (P <0.05), and negatively with MAP and FIns (P <0.05). The serum TNF-αwas positively correlated with HDL-C (P <0.05), and negatively with BMI, TG, MAP and FIns (P <0.05).Multiple stepwise regression analysis showed that FBG, FIns and HOMA-IR were relative independent factors of se-
rum VF and TNF-α(P <0.05).CONCLUSION: Serum levels of VF and TNF-αare closely related to IR.
