Objective To investigate the different impacts of the components of metabolic syndrome (MS) on cardiovascular disease (CVD) risk factors and Framingham risk value (FRV) in newly-diagnosed type 2 diabetes mellitus (T2DM) patients without coronary heart disease (CHD).Methods A total of 212 newly-diagnosed T2DM patients was divided into three groups based on the components of MS,including body mass index (BMI),triglyceride (TG),high density lipoproteins cholesterol (HDL-C),and mean arterial pressure (MAP) tertile,respectively.The general CVD risk factors [smoking,BMI,TG,HDL-C,total cholesterol (TC),low density lipoproteins cholesterol (LDL-C),HbA1 C,homeostasis model assessment of insulin resistance (HOMA-IR),and FRV] were compared among the groups.Logistic regression analysis was used to observe the different impact of MS components on CVD risk.Results With the increasing of BMI,TG and MAP tertiles,all the CVD risk factors and the ratio of FRV middle-risk group or high-risk group had the tendency of augmentation.With the increasing of HDL-C tertiles,all the CVD risk factors and the ratio of FRV middle-risk group or high-risk group was in downtrend.Binary logistic regression analysis indicted that BMI,systolic pressure,diastolic pressure,HbA1 c and TG were risk factors of FRV non-low-risk group (middle-risk and high-risk groups),HDL-C was the protective factor.The odds ratios (ORs) of BMI,systolic pressure,diastolic pressure,HbA1 c,TG and HDL-C were 2.794 (95% CI:2.390-2.408),2.601 (95 % CI:1.974-3.701),1.476 (95 % CI:1.231-2.048),2.964 (95 % CI:1.925-3.282),1.464(95% CI:0.934-2.294),and 0.732(95% CI:0.023-0.962),respectively.Logistic stepwise regression analysis indicated that systolic pressure,BMI,HbA1 C,and HDL-C were entered into the regression equation,and the partial regression coefficient was 0.784,1.213,1.679,and-0.854,respectively (P < 0.05 or P < 0.01).Conclusions All the components of MS in newly-diagnosed T2DM were correlated with CVD risk factors.However,they should be weighed differently.

Objective To evaluate the reliability and validity of Bowel Function Index applied to assess the constipation induced by strong opioid drugs for patients with cancer pain.Methods 126 patients with constipation induced by strong opioid drugs for pain caused by cancer were selected.BFI,Patient Assessment of Constipation Symptoms(PAC-SYM) and clinical observations were used to collect data which were conducted for reliability analysis,correlation analysis and tests for several independent samples to evaluate the reliability and validity.Results The internal consistency determined by Cronbach αt was 0.86 for the total BFI score.Significant correlations were found among BFI,PAC-SYM and clinical observations.The BFI total score and each item scores of three groups all showed significant differences.Conclusions The Chinese version of BFI is a simple,valid and reliable,clinically relevant tool to assess the constipation induced by strong opioid drugs for pain caused by cancer.

Objective To investigate the relationship between the methylation of CpG island of RUNX3 gene promoter and its expression in a human cutaneous malignant melanoma cell line A375, and to assess the role of RUNX3 gene methylation in the pathogenesis of human cutaneous malignant melanoma. Methods Cultured A375 cells were treated with various concentrations (0, 1, 5, 10, 20 μmol/l) of 5-azacyti-dine for 24 or 72 hours followed by another 5 days of culture. Then, methylation-specific PCR (MSP) was performed to evaluate the methylation status of RUNX3 promoter region, and Western-blot analysis to detect the protein expression of RUNX3 in A375 cells. Results The RUNX3 gene promoter region was hypermethylated in untreated A375 cells, along with the absence of protein expression of RUNX3. However, after the treatment with 5-azacytidine, the promoter region of RUNX3 gene was demethylated partly, and the expression of RUNX3 protein was restored in A375 cells. Further, the expression intensity was directly correlated with the concentration of 5-azacytidine. Conclusions The promoter hypermethylation of RUNX3 gene may be related to the silencing of RUNX3 gene expression in A375 cells, whereas 5-azacytidine can cause the demethylation of RUNX3 gene, reactivate the gene which has been inactivated by the promoter hypermethylation, and finally induce the re-expression of RUNX3 protein.

Objective To study the effects of Pervanadate(Per) on BET-2 cells cell cycle arrest and apoptosis induced by ionizing radiation. Methods The BET-2 cells were radiated with 0, 1, 3, 5, 7, 10 Gy and divided into PTP(protein tyrosine phosphatases)-specific inhibitor Per-treated group and non-pervanadate group(served as a control) and then incubated after ?-ray irradiation. Cell cycle and apoptosis were measured by FCM and Hematoxylin-Eosin staining at different time phases. Results G2/M phase arrest and apoptosis were induced in a pattern of dose-effect and time-course after irradiation in the BET-2 cells. In Per-treated group, G2/M phase arrest increased more notably, and apoptosis decreased markedly. Conclusions These studies suggested that Pervanadate potentialy enhance the ratio and prolong the term of G2/M phase arrest, and facilitate the damaged hematopoietic cells to be repaired, remarkably prevent radiated-cells from apoptosis.
