Association of the triglyceride-glucose index with subclinical left ventricular dysfunction in type 2 diabetes mellitus patients: A retrospective cross-sectional study.

Aims/introduction: The triglyceride-glucose (TyG) index is a simple and reliable indicator of insulin resistance, and is associated with the development and poor outcomes of cardiovascular disease. Subclinical left ventricular dysfunction (SLVD) is frequently detected in approximately one-third of diabetes patients, but it has not been established whether the TyG index correlates with SLVD. We carried out this research to evaluate the relationship between the TyG index and SLVD in type 2 diabetes mellitus patients.

Impaired Cognitive Function in Patients With Autonomous Cortisol Secretion in Adrenal Incidentalomas.

Context: Glucocorticoids have potent effects on the central nervous system. However, while patients with Cushing syndrome frequently report impairments in cognitive function, studies investigating cognitive function in patients with autonomous cortisol secretion (ACS) in adrenal incidentalomas (AIs) are scarce.

Objective: The aim of the present study was to evaluate neurocognitive function in patients with ACS.

One repeated transplantation of allogeneic umbilical cord mesenchymal stromal cells in type 1 diabetes: an open parallel controlled clinical study.

Background: The preservation or restoration of β cell function in type 1 diabetes (T1D) remains as an attractive and challengeable therapeutic target. Mesenchymal stromal cells (MSCs) are multipotent cells with high capacity of immunoregulation, which emerged as a promising cell-based therapy for many immune disorders. The objective of this study was to examine the efficacy and safety of one repeated transplantation of allogeneic MSCs in individuals with T1D.

Serum- and glucocorticoid-inducible kinase 1 promotes insulin resistance in adipocytes via degradation of insulin receptor substrate 1.

Aims: Accumulating evidence indicates that serum- and glucocorticoid-inducible kinase 1 (SGK1) plays a role in the development of metabolic syndrome via a poorly understood mechanism. This study aimed to investigate the direct effect of SGK1 on insulin sensitivity in adipose tissue.

Materials And Methods: We ectopically expressed or silenced SGK1 in adipocytes via lentiviral transfection, measured glucose uptake and evaluated insulin signalling using western blotting.

Cardiovascular effects and mechanisms of sodium-glucose cotransporter-2 inhibitors.

Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) are a new type of drug for the treatment of diabetes, and they have been proven to have a good hypoglycemic effect. Several lines of clinical evidence have shown that SGLT2 inhibitors can significantly reduce the risks of atherosclerosis, hospitalization for heart failure, cardiovascular death, and all-cause mortality and delay the progression of chronic kidney disease. Because of the protective effects of SGLT2 inhibitors on the heart and kidney, they are being studied for the treatment of heart failure and chronic kidney disease in patients without diabetes.

Machine Learning Models in Type 2 Diabetes Risk Prediction: Results from a Cross-sectional Retrospective Study in Chinese Adults.

Type 2 diabetes mellitus (T2DM) has become a prevalent health problem in China, especially in urban areas. Early prevention strategies are needed to reduce the associated mortality and morbidity. We applied the combination of rules and different machine learning techniques to assess the risk of development of T2DM in an urban Chinese adult population.

The captopril challenge test for diagnosing primary Aldosteronism in a Chinese population.

Background: The Captopril challenge test (CCT) is an easy-conduct confirmatory test for diagnosing primary aldosteronism (PA). Guidelines show that plasma aldosterone is normally suppressed by captopril (> 30%) in primary hypertension (PH) and in healthy people. It is unclear whether this standard is applicable in Chinese subjects.

Effects of exenatide versus insulin glargine on body composition in overweight and obese T2DM patients: a randomized controlled trial.

Background: Weight loss, especially fat mass reduction, helps to improve blood glucose control, insulin sensitivity, and β-cell function. This study aimed to compare the effect of exenatide and glargine on body composition in overweight and obese patients with type 2 diabetes (T2DM) who do not achieve adequate glycemic control with metformin.

Methods: We performed a prospective, randomized study of 37 overweight or obese patients with T2DM who had inadequate glycemic control with metformin.

Changes in HbA1c and glycaemic parameters from baseline to Day 28 were assessed.

Expression and Histopathological Significance of Disabled-2 in Aldosterone-Producing Adenoma.

The current pathological diagnosis of aldosterone-producing adenoma (APA) is challenging because no histological markers of aldosterone production are available in routine practice. A previous study demonstrated that Disabled-2 (DAB2) is a specific marker of the () in rodents. The aim of the present study was to investigate the significance of immunohistochemical staining to detect DAB2 in the adrenal tissue of patients with APA.

Liraglutide Enhances the Efficacy of Human Mesenchymal Stem Cells in Preserving Islet β-cell Function in Severe Non-obese Diabetic Mice.

Glucagon-like peptide 1 (GLP-1) can promote islet β-cell replication and function, and mesenchymal stem cells (MSCs) can inhibit T cell autoimmunity. This study aimed at testing the dynamic distribution of infused human MSCs and therapeutic effect of combined MSCs and Liraglutide, a long-acting GLP-1 analogue, on preserving β-cell function in severe non-obese diabetic (NOD) mice. We found that infused MSCs accumulated in the pancreas at 4 weeks post infusion, which was not affected by Liraglutide treatment.

The effectiveness of zinc supplementation in men with isolated hypogonadotropic hypogonadism.

A multicenter, open-label, randomized, controlled superiority trial with 18 months of follow-up was conducted to investigate whether oral zinc supplementation could further promote spermatogenesis in males with isolated hypogonadotropic hypogonadism (IHH) receiving sequential purified urinary follicular-stimulating hormone/human chorionic gonadotropin (uFSH/hCG) replacement. Sixty-seven Chinese male IHH patients were recruited from the Departments of Endocrinology in eight tertiary hospitals and randomly allocated into the sequential uFSH/hCG group (Group A, n = 34) or the sequential uFSH plus zinc supplementation group (Group B, n = 33). In Group A, patients received sequential uFSH (75 U, three times a week every other 3 months) and hCG (2000 U, twice a week) treatments.

SGK1 inhibitor reverses hyperglycemia partly through decreasing glucose absorption.

This study investigates the effectiveness and mechanisms of a serum- and glucocorticoid-inducible kinase 1 (SGK1) inhibitor in counteracting hyperglycemia. In an in vivo experiment, we demonstrated that after an 8-week treatment with an SGK1 inhibitor, the fasting blood glucose and HbA1c level significantly decreased in db/db mice. RT-PCR and western blot analyses revealed that intestinal SGK1 and sodium glucose co-transporter 1 (SGLT1) expression were enhanced in db/db mice.

Mutation analyses in pedigrees and sporadic cases of ethnic Han Chinese Kallmann syndrome patients.

Kallmann syndrome, a form of idiopathic hypogonadotropic hypogonadism, is characterized by developmental abnormalities of the reproductive system and abnormal olfaction. Despite association of certain genes with idiopathic hypogonadotropic hypogonadism, the genetic inheritance and expression are complex and incompletely known. In the present study, seven Kallmann syndrome pedigrees in an ethnic Han Chinese population were screened for genetic mutations.
