Risk factors for coronary heart disease in type II diabetes mellitus

Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. An attempt has been made to evaluate the risk factors for coronary heart disease in type II diabetics. In the present study the levels of fasting and postprandial plasma glucose, total cholesterol, low density lipoproteins, triglycerides were high and the levels of high density lipoproteins were low in the type II diabetics compared to controls. The markers of free radical induced injury i.e. malondialdehyde and nitrite/nitrate were high while total antioxidant status a marker for antioxidant protection against reactive oxygen species was low in diabetics compared to controls. The study therefore suggests the importance of assessing these markers of oxidative stress and antioxidant capacity along with the other routine investigations in diabetic patients for initiating antioxidant therapy in addition to primary and secondary preventive measures to mitigate the devastating consequences of diabetes leading to coronary heart disease.     

Treatment of streptozotocin induced diabetes in male rats by immunoisolated transplantation of islet cells

Insulin injection is the main way to combat against insulin-dependent diabetes mellitus effects. Today in some laboratories in the world, the investigators are trying to find some treatments for this disease with insulin-secreting pancreatic islet cells transplantation. Donor tissue in each step of work was prepared from 36 adult male wistar Rats weighted 250–300 grams (75–90 days). Transplantation was done in rats after 2–4 weeks induction of diabetes with 60mg/kg of streptozotocin injection by intravenous method. Encapsulation of pancreatic islet cells allows for transplantation in the absence of immunosuppression. This technique that is called “immunoisolation” is based on the principle that transplanted tissue is protected for the host immune system by an artificial or natural membrane. In this study, the levels of insulin, C-peptide and glucose in diabetic rats have been reached to normal range as compared to un-diabetic rats in 20 days after transplantation of islet cells, so that testis is immunoisolated place for islet cells transplantation. Inside the testis subcutaneously and intrapretoneally implantation of pure islet cells graft, that is a natural immunoisolation method, rapidly and permanently normalized the diabetic state of streptozocin-administered animals.     

诺和锐30特充对2型糖尿病患者血浆C-反应蛋白的影响

目的：观察诺和锐30特充对2型糖尿病患者血浆C-反应蛋白的影响。方法：选择80例2型糖尿病病人,随机分为诺和锐治疗组及诺和灵30R治疗组,诺和锐为餐前即刻皮下注射,诺和灵30R为餐前30min皮下注射,观察两组病人治疗前后餐前、餐后血糖及血浆C-反应蛋白（C-reactive protein,CRP）情况。结果：诺和锐治疗组餐后血糖水平低于诺和灵30R组（P〈0.01）,诺和锐治疗组治疗后C反应蛋白水平明显低于诺和灵30R治疗组（P〈0.01）。结论：对于2型糖尿病患者,诺和锐疗效优于诺和灵30R,而且可以显著降低血浆CRP的水平。

1型糖尿病的细胞和分子致病机理

1型糖尿病是把自身免疫系统对胰岛β细胞进行特异性损伤作为特征的自身免疫疾病,其中β细胞自身抗原,T淋巴细胞,B淋巴细胞及巨噬细胞对胰岛β细胞的损伤起重要作用。

Clinicopathological spectrum of non-alcoholic fatty liver disease among patients in Kerala

Non-alcoholic fatty liver disease and its more aggressive form, non-alcoholic steatohepatitis are entities that are becoming more and more interesting to the medical community in general. A total of 93 Non-alcoholic fatty liver disease patients (64 male and 29 female) within the age range between 28 to 63 years were studied. All of them showed elevated alanine aminotransferase level (104.07 ± 56.04). Aspartate aminotransferase level (58.13 ± 31.96) was elevated more than its normal level in 82% cases and AST to ALT ratio was found 0.59 ± 0.26. Predisposing factors were diabetes mellitus (37%), obesity (13%) and hyperlipidemia (41%). In addition, 32% of the subjects were overweight.18% of the patients had elevated serum bilirubin. Our findings recommend a lower cutoff value than suggested by the World Health Organization for overweight and obesity among this racial-ethnic group.     

Defining diabetes and assigning responsibility: how print media frame diabetes in New Zealand

Research has analyzed media framing of cause and solution responsibility attribution in diabetes discourse. Studies have not similarly engaged with how media frame diabetes ‘effects’, an integral framing component because it comprises the ‘problem definition’ of diabetes. Moreover, the combination of causal attribution and effects provides a ‘moral evaluation’ on who carries the burden of the disease. This paper asks ‘how does the New Zealand print media frame diabetes definition and responsibility attribution?’ We identify key frames used to discursively construct Gestational, Type 1 and Type 2 diabetes discourse. Content and thematic analysis reveal that media predominantly discuss diabetes without type-specification and with a high reference to obesity and behavioral choices as causal factors. Diabetes is defined as an individual’s medical concern, which when mismanaged results in amputation, blindness, kidney disease and coronary disease. We consider the implications of media coverage on public response to diabetes as a societal concern.     

The Relationship Between Social Support and Type 2 Diabetes Risk

Prior research links social support with several positive health outcomes. However, less is known about the association between social support and Type 2 diabetes risk factors, such as glycemic control. This study uses a nationally representative sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the relationship between social support and glycated hemoglobin A1c (HbA1c) levels. The data were analyzed through hierarchical logistic regression. Results indicate an inverse relationship between elevated HbA1c levels and individuals’ satisfaction with their partners’ daily interactions. Implications include the possibility of reducing Type 2 diabetes risk through communication interventions highlighting the importance of maintaining positive daily interactions.     

Impaired hypothalamic-pituitary-gonadal axis function in men with diabetes mellitus

In view of association of diabetes mellitus and male infertility, present study was designed to investigate the functional status of hypothalamic pituitary gonadal (HPG) axis in diabetic men. Thirty-five diabetic men (BMI 22.24±0.21) in the age group 20–40 (30.6±4.7) years were selected. Twenty-five healthy men (BMI 23.85±0.25), in the same age group (29.5±4.8) served as control. Blood samples were collected for hormonal and biochemical estimations. Diabetic men had significantly low serum testosterone with low LH and FSH, hypercholesterolemia, hypertriglyceridemia, hypoalbuminemia and increased oxidative stress. Low serum testosterone in diabetic men was accompanied by low LH and FSH; the inability of the pituitary gland to respond appropriately to a decline in testosterone implying central effect of high serum glucose on the interaction between the nervous and endocrine system. Nutritional deficiency, increased oxidative stress and increased aromatase activity due to excessive body fat might have also contributed to low serum testosterone.
