Objective: To explore the relationship between insulin sensitivity index （ISI）and extent of coronary atherosclerosis in Uygur and Han nationality patients. Methods: A total of 125 patients with coronary heart disease were enrolled, including 59 Uygur nationality patients and 66 Han nationality patients. There were 42 cases with stable angina pectoris, 52 cases with unstable angina pectoris, 31 cases with old myocardial infarction, 53 cases with type 2 diabetes and 35 cases with hypertension. Relevant medical history of patients [age, body mass index (BMI) etc.] was collected and laboratory examination （blood lipid, fasting blood glucose, fasting insulin etc.）were performed, and extent of coronary atherosclerosis was evaluated by coronary angiography in all patients. ISI was calculated and its relationship with extent of coronary atherosclerosis was analyzed. Results: In both nationality patients, ISI was negatively correlated with extent of coronary atherosclerosis (Han nationality: r=-0.71, P=0.03, Uygur nationality: r=-0.52, P=0.04). ISI was negatively correlated with BMI, glycosylated hemoglobin (HbA1c) and low density lipoprotein –cholesterol (LDL-C) (r=-0.45, -0.68, -0.55, P<0.05 all) in Han nationality patients; ISI was positively correlated with high density lipoprotein–cholesterol (HDL-C, r=0.67, P<0.01), and negatively correlated with HbA1c, LDL and lipoprotein a (r=-0.47, -0.35, -0.42, P<0.05) in Uygur nationality patients. Conclusion: Insulin resistance participates and promotes formation and development of coronary atherosclerotic plaques. Controlling weight, blood glucose and LDL-C levels etc. can decrease insulin resistance and prevent occurrence and development of coronary heart disease.

This study explored a novel systemic community-based model for detecting and managing people living with HIV/AIDS (PLWHA). Both quantitative and qualitative research methods were used in this study. A quantitative questionnaire investigation was conducted in a sample of 1192 subjects which were randomly selected from two areas with high HIV prevalence, Xiangfan City and Shiyan City of Hubei Province, China. Twenty-two medical and health service staffs were interviewed by semi-structured questionnaire focusing on awareness, status, problems, and suggestions about community-based Voluntary Counseling and Testing and Provider Initiated Testing and Counseling (VCT/PITC). And they were organized to discuss about the aforementioned issues in Xiangfan City and Shiyan City, respectively. Our results showed that the accessibility and availability of the general VCT/PITC were bad. About 28.3% had known and only 4.9% had made use of VCT/PITC. Developing community-based VCT/PITC had some special advantages that can overcome some existing problems to remedy the aforementioned defects. We are led to conclude that, to maximize the availability and uptake rate of the VCT/PITC, we plan to detect PLWHA by developing the community-based VCT/PITC through 4 paths. Then we establish the community HIV health care center constituted of 8 sectors to provide an overall management. Thus, we can effectively detect and manage the PLWHA with a new systemic community-based model.

Objective To investigate the role of miR-592 in the Glioma.Methods We first analyzed the expression of miR-592 in Glioma tissues from patients by quantitative PCR.We transfected U251 cells with miR-592 mimics and then detected the growth of cells by MTT assay.We performed dual-luciferase reporter assay and western blot assay to examine whether Runx2 was the direct target of miR-592 in U251 cells.In order to test whether Runx2 was the functional target of miR-592,we determined the cell growth curve by down-regulating the level of Runx2.Moreover,we also detected the apoptosis of U251 after Runx2 knockdown.Results The expression of miR-592 was significantly reduced in glioma tissues (t=2.752,P--0.013).Over-expression miR-592 remarkably increased the apoptotic rate of U251 cells compared with the control group (t=2.127,P=0.031;t=2.284,P=0.026).Flow cytometry analysis showed that MiR-592 significantly promoted apoptotic cell death of U251 cells Apoptosis rate was 7.2％±0.68％ in miR-592 group and 17.47％±1.45％ in control group (t=3.294,P=0.007).The results of double luciferase assay and Western blot assay showed that miR-592 directly targeted the 3'Runx2 of-UTR to inhibit the level of Runx2 protein.The effect of down-regulation of Runx2 on the growth of U251 cells was detected,the results showed that growth was significantly slower in the cells transfected with Runx2 siRNA than in those without Runx2 siRNA (t=3.124,P=0.O11).Detection of cycle by flow cytometry showed that runx2 down-regulated the apoptosis rate of U251 cells.Tumor growth curve showed that overexpression of miR-592 significantly inhibited tumor growth and the down regulation of Runx2 expresssion also significantly inhibited tumor growth.Conclusion miR-592 suppresses the growth and promotes the apoptotic rate of U251 cells by targeting Runx2.

Objective:To determine the reliability and validity of the Chinese version of Fagerstrom Test for Nicotine Dependence (FrND) scale among smoking male inpatients with schizophrenia.Methods:Two hundred and twenty smoking male inpatients,who met criteria for schizophrenia of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ),were consecutively included.FTND scale and Russell's Reasons for Smoking Questionnaire (RRSQ) were used to assess subjects'severity of nicotine dependence and addiction score of the dimension of reason for smoking,respectively.According to the principle of voluntariness,37 subjects were selected and re-assessed with FTND scale after two-week interval.Reliability,correlation and factor analyses were used to examine the reliability and validity.Results:The Cronbach α (internal consistency) and two-week re-test reliability coefficients of FTND scale were 0.68 and 0.72 (P ＜0.01),respectively.The criterion related validity coefficient with addiction score of RRSQ was 0.53 (P ＜0.01).Two common factors were abstracted from the scale factor analysis,accounting for 52.4％ of the total variance.There were statistically significant differences between patients with different duration of illness,number of hospitalizations and age of smoking initiation (P ＜0.05).Conclusion:The Chinese version of FTND scale for smoking male inpatients with schizophrenia has a relatively low internal consistency and good re-test reliability,criterion related validity,construct validity and empirical validity.
