Abstract
Alterations in carbohydrate metabolism are frequently observed in cirrhosis. We conducted this study to define the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in patients with chronic liver disease (CLD), and explore the factors that may be potentially associated with the development of DM in these patients.
Methods: From October 2002 to March 2003, 185 consecutive patients with CLD, who referred to "Tehran Hepatitis Center", were enrolled into the study. Fasting plasma glucose and two-hour plasma glucose were measured in patients' sera. DM and IGT were diagnosed according to latest American Diabetes Association criteria.
Results: The subjects included 42 inactive HBV carriers, 102 patients with HBV or HCV chronic hepatitis, and 41 cirrhotic patients. Mean age was 43.8±12.0 years ranging between 22 to 84 years. DM and IGT were diagnosed in 40 (21.6%) and 21(11.4%) patients, respectively. Univariate analysis showed that age (P=0.000), CLD status (P=0.000), history of hypertension (P=0.007), family history of DM (P=0.000), and body mass index (BMI) (P=0.009) were associated with DM. Using Multivariate analysis, age (P=0.01), family history of DM (P=0.0001), chronic hepatitis (0.0004), and cirrhosis (P=0.0004) remained as the factors independently associated with DM. When patients with cirrhosis and chronic hepatitis were analyzed separately, higher Child-Pugh's score in cirrhosis (P=0.04) and older age (P=0.04), higher fibrosis score (P=0.04), and higher BMI (P=0.003) in patients with chronic hepatitis were found to be associated with higher prevalence of DM. Conclusion: Our findings indicated that patients with cirrhosis and chronic hepatitis are at risk of developing DM. Older age, sever liver disease, and obesity were associated with development of DM.

Abstract
Background: Obesity and type 2 diabetes can impair the function of cells, including CREB and CRTC2 proteins, which are important for regulating adipose tissue metabolism. Therefore, the purpose of the present study was to investigate the effect of eight weeks of high intensity interval training (HIIT) on CREB and CRTC2 proteins levels in subcutaneous adipose tissue of obese rats with type 2 diabetes.
Methods: In this experimental study, 12 head two-month-old Sprague-Dawley rats with a mean weight of 300±20 g were selected. After diabetic induction with Streptozotocin and Nicotinamide, rats were randomly assigned to two groups, diabetic training (6 heads) and diabetic control (6 heads). The training groups performed the training program 4 days a week for 8 weeks, including 5
interval 4-minute with an intensity of 85 to 95% of the maximum speed, and 3-minute active rest periods with an intensity of 50 to 60% of the maximum speed; SPSS software version 23 and independent t-test were used to analyze the data.
Result: After eight weeks of HIIT training, no significant change in CREB protein level was observed in the
training group compared to the control (P<0.22); However, a significant increase in CRTC2 protein level was observed in the training group compared to the control (P<0.005);
Conclusion: HIIT training did not result in a change in CREB protein level. But, it was able to increase the CRTC2 protein level, which could lead to the regulation of adipose tissue metabolism in diabetic subjects.

Abstract
Background: Diabetes leads to numerous side effects in the cardiovascular system and also to improper functioning of the body's antioxidant system. The aim of this study is to investigate the effect of six weeks of high-intensity interval training with coenzyme Q10 supplementation on the values of Nrf2 and NQO1 in heart muscle of elderly diabetic rats.
Methods: In this experimental study, 48 elderly male rats (18 months old) were randomly divided into four groups of intense aerobic exercise with coenzyme Q10 supplementation, intense aerobic exercise group, coenzyme Q10 supplement intake group, and control group. Induction of diabetes was done by injecting a single dose of streptozotocin in the amount of 60 mg/kg intraperitoneally. The program of high intensity interval training was done for six weeks. Coenzyme Q10 supplement group received orally at a dose of 200 mg/kg. Western blot method was used to measure Nrf2 and NQO1 values. The data were analyzed by one-way analysis of variance and Tukey's post hoc test at a significance level of P <0.05.
Results: The results showed taking coenzyme Q10 supplement (P= 0.014), intense intermittent exercise (P= 0.001) and intense intermittent exercise with coenzyme Q10 supplement (P= 0.001) significantly increased Nrf2 values in the hearts of diabetic elderly rats. Also, the use of coenzyme Q10 supplement (P=0.0366), intense intermittent exercise (P= 0.014) and intense intermittent exercise along with coenzyme Q10 supplement use (P= 0.002) significantly increased the amount of NQO1 in the hearts of diabetic aged male rats.
Conclusion: Intermittent intense training along with supplement consumption improves heart function in elderly diabetic patients through increasing endogenous antioxidant enzymes.
