Objective To compare the differences of three diagnostic criterions for metabolic syndrome (MS) proposed by the International Diabetes Federation (IDF) in 2005, the Third Report of National Cholesterol Education Program-Adult Treatment Panel Ⅲ (NCEP-ATPⅢ) in 2005 and Chinese Diabetes Society(CDS)in 2004 in population of Xilinguole city in inner mongolia. Methods 1 060 employees aged more than 20 yrs in enterprises taken health examination in Xilinguole hospital were investigated by epidemiological survey and the prevalence rates of MS and its components were calculated according to these three definitions respectively, and compared the agreement rates and difference between these definitions. Results The age-adjusted MS prevalence rates were 25.0%, 27.9% and 22.5% according to IDF (2005), ATPⅢ (2005) and CDS (2004) respectively. The agreement rate of diagnosis between IDF and ATPⅢ was the highest, and the Kappa value was 0.929. The kappa values between IDF and CDS,ATPⅢ and CDS were 0.726 and 0.763, respectively. There were 4.3% and 10.8% subjects respectively without MS diagnosed by IDF and CDS criterion presented at least 3 risk factors respectively. For Mongolia nationality people, when the waist circumference was 90cm in male and BMI was 25kg/m2 in female, the sensitivity and specificity were relative better, and the distance of ROC curve was the shortest, but for Han nationality, BMI≥25 kg / m2 in male and waist circumference ≥80 cm was better. Conclusion ATPⅢ definition can screen out the highest prevalence of MS and risk factors aggregation among three definitions, and it's best for screening for the high risk population of cardio-cerebrovascular diseases. The cutoff value of waist circumference (WC) in IDF and ATP Ⅲ seems better for Mongolia nationality men; while the cutoff value in CDS was better for Han nationality men. We should combine waist circumference and body mass index to judge the condition of obesity.

Objective To study the expression and clinical significance of Survivin and PTEN in cervical carcinoma. Methods The expression of Survivin and PTEN in 60 cases of cervical carcinoma, 15 cases of CIN Ⅰ , 15 cases of CIN Ⅱ, 15 cases of CIN Ⅲ and 15 cases of normal cervical tissues were detected by immunohistochemical staining. Results The expression positive rates of Survivin were 86.67 %, 80.00 %,33.33 %, 20.00 % and 0, respectively, and those of PTEN were 21.67 %, 40.00 %, 80.00 %, 86.67 % and 100.00 % in cervical carcinoma, CIN Ⅲ, CIN Ⅱ, CIN Ⅰ and normal cervical tissues, respectively. The expression positive rates of Survivin were increased along with normal cervical epithelium, CIN Ⅰ, CIN Ⅱ,CIN Ⅲ and invasive carcinoma of cervix;while those of PTEN were inverse order.Compared with the expression positive rates of Survivin and PTEN protein in the CIN Ⅱ group, those in the CIN Ⅲ group had significant differences (P <0.01 and P <0.05, respectively). Expressions of Survivin and PTEN were correlated to the size of focus(P <0.05), the depth of tumor and pelvic lymphnode metastasis (P <0.05), but not to clinical staging, pathological types, pathological grading and age(P >0.05). There was a negative correlation between the expression of PTEN and Survivin in cervical carcinoma. Conclusion The expressions of Survivin and PTEN are correlated with invasion and metastasis of cervical carcinoma, and be related to clinical pathotology.Survivin and PTEN may play a important role in the formation, proliferation, differentuation and metastasis of cervical carcinoma. They may be used as markers of early diagnose, efficacy and prognosis evaluation.

In order to examine the strong anticancer action and low toxicity of Trichostatin A (TSA), the effect of TSA was examined on the growth inhibition, acetylation of histone H3 and apoptosis in HL-60 cells by employing MTT, immunocytochemical techniques, and Annexin-V-FITC/ PI assay. Our results showed that TSA could inhibit proliferation of HL- 60 cells in a time- and dose-dependent manner, and the IC50 at the 36th h was 100 ng/ml. The apoptosis-inducing effect of TSA on HL-60 cells was also time- and dose-dependent. But it didn't demonstrate apparent apoptosis induction in NPBMNCs within specific dose and time range. Both of the acetylation of histone H3 in HL-60 cells and NPBMNCs increased significantly (P<0.05) after treated with 100 ng/ml TSA for 4 h. However, there was no significant differences between the two groups (P>0.05). It is concluded that TSA can inhibit growth and induce apoptosis of HL-60 cells in a time- and dose-dependent manner, and is able to selectively induce apoptosis in HL-60 cells but does not respond in NPBMNCs under the same conditions. The difference of TSA between HL-60 cells and NPBMNCs can't be explained by the regulation of histone acetylation.

In order to identify family factors obviously relevant to aggression, and offer a theoretical foundation for the prevention of aggression, 4010 students from primary and secondary schools in 5 different areas in Hubei province were surveyed. The Child Behavior Checklist " parents' form" (Chinese version) and the four scales of Family Environment Scale were used. A multiple logistic regression was used to identify risk factors of children's and adolescents' aggressive behavior. The results showed that maternal education, paternal occupation, family type, parental child-rearing attitude and patterns, students' interpersonal relationship were significantly associated with the children's and adolescents' aggression. The risk factors of aggression were parental child-rearing patterns, peer relationship, teacher-student relationship, and family conflicts.
