BACKGROUND
The target of the treatment of metabolic syndrome and diabetes is an improvement of insulin resistance. D-chiro-inositol (DCI) plays a role in a phospholipid mediating intracellular insulin action. In the previous studies, the urine level of DCI were decreased in the diabetic animal with insulin resistance. Some clinical studies showed that DCI improved a glucose level and HbA1c. Therefore we studied the relationship between DCI and glucose metabolism, especially insulin resistance. METHODS: To investigate the mechanism of DCI affecting the glucose metabolism, we examined the effects of DCI on 2-deoxyglucose uptake, gene expression of adipocytokines and AMPK pathway by using RT-PCR and western blot in 3T3-L1 cells. RESULTS: Insulin-stimulated 2-deoxyglucose uptake increased in DCI-treated cells by about 1.2-fold (relative to the control) and was inhibited by phosphoinositide 3-kinase (PI3 Kinase) inhibitors (Wortmanin, LY294002) and AMPK inhibitor (STO-609). In Western blot analysis, it didn't show the difference of phosphorylation of Akt and AMPK between DCI-treated group and control in 3T3-L1 cells. However, DCI decreased the gene expression of resistin in 3T3-L1 cells. CONCLUSION: DCI may involve other pathway of insulin signaling, but not PI3 Kinase and AMPK signaling pathways and it may be useful in managing metabolic syndrome by improving insulin resistance through increasing glucose uptake and decreasing resistin relevant to insulin resistance.

BACKGROUND
Adiponectin is secreted from adipose tissue and plays an important role in the regulation of glycemia and insulin resistance. In this study, the relationship between adiponectin and the adiposity, body composition, insulin sensitivity, lipid profile were respectively examined in newly diagnosed type 2 diabetes. METHODS: Total 1993 were participated in the Korea Rural Genomic Cohort Study (Geumsan County). After a 12-hour overnight fast, all subjects underwent 75-g oral glucose tolerance test. 105 of those were studied as newly diagnosed type 2 diabetes. The body composition was analyzed by means of bioelectric impedance analysis and the insulin sensitivity was estimated by fasting insulin, HOMA-IR and QUICKI method, respectively. RESULTS: Adiponectin positively correlated with high-density lipoprotein cholesterol (r = 0.246, P < 0.05). Adiponectin inversely associated with waist circumference (r = - 0.408, P < 0.01), triglyceride (r = -0.274, P < 0.05), ferritin (r = -0.260, P < 0.05), visceral fat (r = -0.248, P < 0.05), high sensitivity C-reactive protein (r = -0.228, P < 0.05) and body mass index (r = -0.225, P < 0.05). In multiple linear regression, waist circumference and high-density lipoprotein cholesterol were analyzed as independent variables of serum adiponectin. CONCLUSION: Adiponectin concentrations were closely related to waist circumference in newly diagnosed type 2 diabetes.

BACKGROUND
The prevalence of diabetes mellitus has increased recently. The morbidity and mortality of diabetic patients are mainly caused by chronic complications, especially cardiovascular events. N-terminal proB-type natriuretic peptide(NT-proBNP) is a neurohormone that is secreted from ventricular myocardium due to myocardial dilatation or pressure overload. NT-proBNP has prognostic value, and reflects cardiac function in patients with myocardial infarction or heart failure. This study was performed to evaluate functional changes of the heart, according to the degree of albuminuria and the prognostic value of NT-proBNP in type 2 diabetic patients. METHODS: 57 patients with type 2 diabetes were divided into three groups according to their degree of albuminuria, these being normal(below 30mg/day), microalbuminuria(30 between 300mg/day) and overt proteinuria(over 300mg/ day). The clinical parameters in each of the patients were evaluated, echocardiography performed and the levels of NT-proBNP checked, and compared between the three groups. RESULTS: Of the 57 patients with type 2 diabetes the male:female ratio of 32:25, with mean age, duration of diabetes and BMI of 55.8+/-10.1 and 11.3+/-8.2 years, and 23.2+/-4.0kg/m2, respectively. Twenty-eight patients showed normal(49.1%), 15 microalbuminuria(26.3%) and 14 overt proteinuria(24.6%). The age, BMI, diastolic BP and glycosylated hemoglobin showed no significant difference between the three groups. The duration of diagnosed diabetes was significantly longer, the systolic blood pressure and serum creatinine levels significantly higher and the serum hemoglobin significantly lower (p<0.05) in the overt proteinuria compared to the normal group. The duration of diabetes was significantly longer and serum creatinine levels significantly higher in the overt proteinuria than the microalbuminuria group(p<0.05). The echocardiographic data showed no difference among the groups. The NT-proBNP levels also showed no significant difference, but tended to be elevated toward albuminuria. CONCLUSION: The cardiac function and NT-proBNP levels showed no significant difference between each of the albuminuric groups. This study suggests that the degree of albuminuria is not a predictive factor for changes of the cardiac function and NT-proBNP levels

AbstractAbstract PDF
BACKGROUND
Diabetes mellitus has a major impact on cardiac morbidity and mortality. We analyzed the clinical characteristics and coronary angiographic findings in patients with a coronary artery disease and with noninsulin dependent diabetes mellitus. METHODS: We retrospectively reviewed the clinical and coronary angiographic findings in 74 patients with noninsulin dependent cliabetes mellitus and in 328 non-diabetic patients who had a coronary insufficiency. RESULTS: Significant coronary occlusions and multiple coronary artery diseases were more common in diabetics than in non-diabetics. The patients with noninsulin dependent diabetes mellitus has several limiting factors to perform the successful percutaneous coronary angioplasty, it could be a possible factor for rapid deterioration of coronary insufficiency in patients with diabetes mellitus. Smoking and hypertension significantly increased the incidence of signiftcant coronary occlusions whereas obesity and hypercholesterolemia did not any significant influence on incidence of the significant coronary occlusions. The longer duration of diabetes rnellitus associated with higher incidence of significant coronary occlusions and multiple coronary diseases. CONCLUSION: Significant coronary occlusions and multiple coronary artery diseases were occurred more common in diabetics than in non-diabetics. Coronary angiography should be performed routinely in noninsulin dependent diabetes.
