The mechanism of damage in monocytes with the oxidation inhibitor α-lipoic acid (ALA) was observed under intermittent high glucose condition.The results showed that fluctuating high blood glucose levels led to more damage than that under constant high blood glucose level in monocyte,and antioxidant α-ALA could ameliorate the oxidative stress.The high level of nuclear factor-κB and monocyte chemotactic protein-1 are probably among the factors that cause vascular damage by deposit of monocytes.

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 investigate the relationship between human leptin receptor(LEPR)gene G3057A polymorphism and type 2 diabetes complicated with non-alcoholic fatty liver disease(NAFLD).Methods 216 cases of newly diagnosed type 2 diabetes(104 cases complicated with NAFLD)and 108 cases of normal glucose tolerances(NGT)were recruited.Hemi-nested PCR-RFLP and PCR direct sequence analysis were conducted to detect the polymorphisms of LEPR G3057A polymorphism.The plasma leptin and insulin levels were measured by ELISA kit.Plasma lipid and glucose metabolic parameters were measured routinely.Liver ultrasound scanning Was carried out among all subjects.Results Type 2 diabetic patients complicated with NAFLD had higher plasma alanine aminotransferase(ALT),triglycerides(TG),low density lipaprotein cholesterol(LDL-C),leptin levels and lower plasma insulin levels than those cages without NAFLD and NGT.The variant frequency at nucleotide 3057 G to A transversion Was 76.0% in type 2 diabetic patients complicated with NAFLD,which Was also significant higher than those cases without NAFLD(62.1%)or NGT cases(53.2%)(x2=14.63,P<0.01).Conclusions The polymorphism of LEPR gene 3057 probably contributes to the onset of NAFLD in type 2 diabetes by regulating lipid metabolism and affecting insulin sensitivity.

AIM:To investigate the effects of C1q/TNF related protein 3 (CTRP3) on the insulin sensitivity of insulin resistant 3T3-L1 adipocytes.METHODS: The insulin resistance model of 3T3-L1 adipocytes was induced by palmic acid cultivation.The adipocytes were treated with different concentrations of recombinant CTRP3 protein (10, 50, 250,1 250 μg/L) for 12 h, and for different times (2, 6, 12, 24 h) at the concentration of 250μg/L.The glucose con-sumption was detected by the glucose oxidase method.The glucose transport ratio was measured by 2-deoxidation-[3H]-glucose intake method.The contents of TNF-αand IL-6 in the supernatant were detected by ELISA.The mRNA expression of TNF-α, IL-6 and glucose transporter-4 (GLUT-4) was measured by real-time PCR.The protein expression of GLUT-4 was detected by Western blotting.RESULTS:Compared with normal control ( NC) group, the glucose consumption and glucose intake ratio of insulin resistance ( IR) group was decreased by 50.6%and 57.9%, respectively.Compared with IR group, with the increase in CTRP3 (10, 50, 250,1 250 μg/L) in intervention groups, the glucose consumptions were in-creased by 22.1%, 42.9%, 76.6% and 80.5%, respectively, and the glucose intake ratios were increased by 39.0%, 68.0%, 108.0%and 111.0%, respectively.With the increased duration (2, 6, 12 and 24 h) of CTRP3 treatment at the concentration of 250 μg/L, the glucose intake ratio was increased by 23.0%, 79.0%, 109.0%and 114.0%, respectively. The contents of TNF-αand IL-6 in the supernatant were decreased by 17.4%and 17.1%respectively as treated with CTRP3 at the concentration of 250 μg/L for 12 h, and the mRNA expression of TNF-αand IL-6 was decreased by 26.0% and 18.9%respectively, while the mRNA and protein expression of GLUT-4 was increased by 61.5%and 55.6%respectively. CONCLUSION:CTRP3 may increase the insulin sensitivity of insulin resistant 3T3-L1 adipocytes by down-regulating the expression of inflammatory factors, improving the insulin signal transduction and increasing the expression of GLUT-4.
