Multi-genic pattern found in rare type of hypopituitarism: a whole-exome sequencing study of Han Chinese with pituitary stalk interruption syndrome.

Pituitary stalk interruption syndrome (PSIS) is a rare type of hypopituitarism manifesting various degrees of pituitary hormone deficiency. Although mutations have been identified in some familial cases, the underpinning mechanisms of sporadic patients with PSIS who are in a vast majority remain elusive, necessitating a comprehensive study using systemic approaches. We postulate that other genetic mechanisms may be responsible for the sporadic PSIS.

Effect of Negative Pressure Wound Therapy on Cellular Fibronectin and Transforming Growth Factor-β1 Expression in Diabetic Foot Wounds.

Background: Chronic diabetic foot wounds are a leading cause of amputation, morbidity, and hospitalization for patients with diabetes. Negative-pressure wound therapy (NPWT) can putatively facilitate wound healing, but the underlying mechanisms remain unclear. Cellular fibronectin (cFN) and transforming growth factor-β1 (TGF-β1) play an important role in wound healing.

Association between Self-reported Snoring and Prediabetes among Adults Aged 40 Years and Older without Diabetes.

Background: Several previous studies have shown that snoring is associated with glucose metabolism and the development of diabetes, but rare study has shown the association between snoring frequency and prediabetes, particularly in China. We hypothesized that individuals who snore might have a higher risk of prediabetes. This study aimed to investigate the association between self-reported snoring and prediabetes in a Chinese population.

Pathophysiology of peripheral arterial disease in diabetes mellitus.

Peripheral arterial disease (PAD) increases the risk of lower extremity amputation. It is also an independent predictor of cardiovascular and cerebrovascular ischemic events, affecting both the quality and expectancy of life. Many studies have demonstrated that the prevalence of PAD in patients with diabetes mellitus (DM) is higher than in non-diabetic patients.

Candesartan cilexetil prevents diet-induced insulin resistance via peroxisome proliferator-activated receptor-γ activation in an obese rat model.

Angiotensin II type 1 receptor (AT1R) blockers (ARBs) have been shown to reduce the incidence of type 2 diabetes mellitus; however, the underlying molecular mechanism is unknown. Peroxisome proliferator-activated receptor γ (PPARγ) is the central regulator of insulin and glucose metabolism, which improves insulin sensitivity. Whether candesartan cilexetil, as a prodrug of the AT1R blocker candesartan, has PPARγ-activating properties remains to be elucidated.

Type B insulin resistance syndrome with Scleroderma successfully treated with multiple immune suppressants after eradication of Helicobacter pylori infection: a case report.

Background: Type B insulin resistance is a rare autoimmune disease characterized by the presence of autoantibodies against the insulin receptor. Helicobacter pylori (H pylori) infection may play a causative role in the autoimmune diseases.

Case Presentation: Here, we present a rare case of a 48-year old female patient, who had type B insulin resistance with systemic scleroderma and was successfully treated with multiple immune suppressants after eradication of Helicobacter pylori infection.

Acquired generalized lipodystrophy in a young lean Chinese girl. Case Report.

Lipodystrophies is a really rare group of diseases characterized by altered body fat amount and/or repartition and serious insulin resistance.We reported a lean Chinese girl with acquired generalized lipodystrophy, who had a long history of poorly controlled diabetes mellitus (DM) despite with extremely high dose insulin (6 u/kg/d) therapy, combined with severe hypertriglyceridemia and acanthosis nigricans. The differential diagnosis of Lipodystrophies should be considered in lean patients presenting with early onset DM, combined with serious insulin resistance.
