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.

Service for key subjects is important for medical information institutions nowadays.This paper discusses the necessity of providing subject-oriented service,and proposes three service modes:information transmission mode,information analysis mode and information navigation mode.In addition,the guarantee measures are also discussed,including constructing a security system for subject literature,training high-quality services team,and promoting subject information service brand.

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.

AIM: To observe the local expression of nuclear factor-?B(NF-?B) in spontaneously hypertensive rat(SHR) kidney and effects of AT1 receptor contagonist valsartan.METHODS: 16 SHRs were randomly divided into two groups: SHR control group and valsartan group.Another 8 WKY rats act as normal control group.Systolic blood pressure(SBP) of SHR was measured at the beginning and the end of 2,4,6 and 8 weeks of intervention treatment.Radioimmunoassay was used to determine the activities of rennin and angiotensin II(AngII).The renal tissue NF-?B protein expression was detected by immunobiochemistry.RESULTS: SBP of SHR was remarkably decreased after valsartan intervention.However,the rennin activities and AngII level in plasma increased in valsartan group.In the renal tissue of SHR,there was remarkably increased in expression of NF-?B protein.Valsartan could significantly reduced NF-?B expression.CONCLUSION: Valsartan can depress NF-?B renal expression in protein level and might benefit hypotension renal function.

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.

AIM:Nitroxyl ( HNO) increases myofilament Ca 2+responsiveness relative to increases in intracel-lular Ca2+in cardiac muscle.In this study, we further investigated this effect of HNO on trabecular muscles from phospho-lamban knockout ( PLB-KO) and wide-type ( WT ) mice using a novel HNO donor , 1-nitrosocyclohexyl acetate ( NCA ) . METHODS:Trabecular muscles were dissected from the right ventricles of the rat hearts and mounted between a force transducer and a motor arm.The muscles were superfused with K-H solution (pH 7.4) at room temperature.Fura-2 was loaded into the trabecular muscles via electrophoresis .The length of the sarcomere was set to 2.2~2.3μm.During stead-y-state activations, the maximal Ca2+-activated force and Ca2+required for 50% activation were measured.RESULTS:The intracellular Ca 2+transients and force of the PLB-KO muscles at baseline were higher than those of the WT muscles and exhibited a negative force-frequency relationship (FFR).NCA (2.5μmol/L) increased systolic force in both PLB-KO group and WT group at any given [Ca2+]o.However, there was more dramatic increase in the force development due to moderate increases in the intracellular Ca 2+transients in the WT muscles when external Ca 2+increased from 1.5 to 4.5 mmol/L under NCA.NCA did not affect the negative FFR in PLB-KO muscle.Steady-state force-Ca2+relations obtained from skinned muscles were not different between the 2 groups, while NCA increased Ca2+responsiveness in skinned mus-cles from both PLB-KO and WT mice.CONCLUSION:HNO increases force development in both PLB-KO and WT mus-cles as a result of increases in myofilament Ca 2+responsiveness .The increased intracellular Ca 2+transients are accompa-nied by greater force development in WT mice , suggesting that HNO improves Ca 2+activation and establishes HNO as a positive inotropic agent with novel mechanisms .
