Rosiglitazone is one of thiazolidinediones (TZD),an antidiabetic agent which improves insulin sensitivity,but the cardiovascular safety of the drug remains controversial.The new re-evaluation of the RECORD trial has suggested that rosiglitazone-containing drugs do not show an increased risk of heart attack compared to the standard type 2 diabetes medicines,such as mefformin and sulfonylurea.The post hoc analysis of the BARI 2D also indicates that rosiglitazone may not relate with the increased risk of major ischemic cardiovascular events.According to these new results,there is no clear evidence that rosiglitazone may increase cardiovascular risk.The U.S.Food and Drug Administration announced in July 2013 that it is requiring the removal of some prescribing and dispensing restrictions for rosiglitazone-containing diabetes medicines.

[Objective] To investigate the clinical characteristics and risk factors of lower-extremity arterial disease in the patients with newly diagnosed type 2 diabetes mellitus combined with nonalcoholic fatty liver disease (NAFLD). [Methods] One hundred fifty-one patients were investigated respectively. The patients were divided into two groups (NAFLD-Group and non-NAFLD group) by liver ultrasonography and disease history, then their clinical data were collected and compared in order to find the differences of biochemical indicators and the morbidity of lower-extremity arterial disease between two groups. [Results] Ninety-two cases (60.93%) were complicated with NAFLD. NAFLD group had higher levels of fast insulin and C peptide level, postprandial insulin and C peptide level, uric acid, body mass index (BMI), homeostasis model assessment (HOMA-IR) and lower level of high-density lipoprotein cholesterol and insulin sensitive index than those of without NAFLD (P<0.05). One hundred and one cases(66.89%) were complicated with lower-extremity arterial disease. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group (75% vs. 54.24%, P<0.01). [Conclusion] Both lower-extremity arterial disease and NAFLD are common complicated with type 2 diabetes. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group.

Objective To compare the excursion of blood glucose (BG) in the type 2 diabetes mellitus treated with oral antidiabetic drugs (OADs) plus glargine or human isophane insulin (HII). Methods A 1 : 1 randomization schedule assigned 30 type 2 diabetics inadequately controlled on OADs (fasting BG>9.0 mmol/L and HbA1C > 8.5%) to 2 groups additionally treated with glargine or HII. The insulin dose was titrated to achieve fasting capillary BG<6.0 mmol/L. Montoring BG with continuous glucose monitoring system, then the standard deviation of BG (SDBG), maximal excursion of BG (LAGE) and coefficient of variation (CV) of fasting plasma glucose (FPG) were calculated. Results SDBG (1.49±0.35 vs 1.73±0.46), LAGE (3.23±0.76 vs 3.73± 1.00) and CV-FPG (17.26±2.24 vs 20.33±3.21) were lower in glargine group than those in HII group (P< 0.05). No difference could be found in hypoglycaemia between two groups. Conclusion OADs plus glargine could make blood glucose more stable than OADs plus HII without increasing the incidence of hypoglycaemia.

Objective To study the effects of sulodexide on islet B-cell function in streptozocin induced di-abetic rats. Methods Sprague-Dawley(SD) rats were randomly divided into normal control group (group C), dia-betic group without treatment(group D), and suledexide treatment group(group S), a single dose of streptozotocin were abdominally injected to establish the diabetic rat models. Each animal in sulodexide treated group was addition-ally fed with sulodexide of 10 mg/(kg·d) for 12 weeks,while the remained group (group C and D) were given normal water in the same period. After 12 weeks of treatment, fasting plasma glucose(FPG),fasting plasma insulin (FINS), activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), triglyceride (TG), Low-density lipoprotein cholesterol (LDL-C), serum creatinine rates (SCr) and alanine aminotransferase (ALT) were measured. Insulin sensitivity index(ISI) and insulin resistant index (HOMA-IR) were calculated. Results After 12 weeks, the levels of TG, LDL-C and ALT had no significant difference between group D and group S, but were higher than those in group C (P <0.05);There were no significant difference of SCr levels among the three groups. Compared with the group C, APTT, PT, TT and ISI in group D and S were significantly decreased, HOMA-IR were significantly increased (P < 0.05). APTT, PT, TT and ISI in group S had significantly increased compared with that in group D, HOMA-IR was significantly decreased in group S compared with that in group D (P < 0.01). Conclusions Sulodexide can reduce insulin resistant, improve hypercoagulability and insulin sensitiv-ity in streptozocin induced diabetic rats. The effects to blood lipid, liver and renal functions in diabetic rats are not obvious.
