Silent Corticotroph Adenomas (SCAs) are a type of pituitary tumor that is discovered without obvious clinical symptoms. SCAs are considered to be one of the five "high-risk" tumors due to their aggressive behavior, characterized by high levels of proliferation, rapid progression, and recurrence. Unlike functional corticotropin adenomas, SCAs do not exhibit any clinical or biochemical signs of hypercortisolemia. When the tumor is detected, it often exhibits invasive gro...

Bariatric surgery, in particular, Roux-en-Y gastric bypass (RYGB), is the most effective treatment for morbid obesity. The restricted gastric capacity and reduced absorption of nutrients cannot account for all the metabolic benefit we observe post-operation. Therefore, we applied metabolic and microbial profiling approach to investigate the potential mechanisms of RYGB surgery. Metabolic profiling strategy is widely applied in the discovery and development of metabolic biomark...

Introduction: Thyroglobulin plays a vital role in the follow-up of patients with differentiated thyroid carcinoma (DTC) after thyroidectomy combined with radioiodine (RAI) ablation. As to preablative stimulated thyroglobulin (ps-Tg), though several studies have manifested its potential in identifying distant metastatic DTC (DM-DTC), it remains unclear whether a single ps-Tg is sufficient for predicting DM-DTC. This retrospective study was aimed to evaluate the utility of seria...

Objective: We longitudinally assessed the overall and age- and sex-specific incidence rates and relative risks of newly diagnosed diabetes mellitus in patients surviving the first-attack acute pancreatitis (AP) as compared to matched controls.Methods: Study cohort included 2966 AP patients and 11 864 non-AP controls individually matched on age, sex and date of index admission, with an AP/non-AP ratio of 1:4. Incidence rate was estimated under Poisson ass...

Objective: Autologous hematopoietic stem cell transplantation (AHSCT) is a promising treatment to reverse type 1 diabetes (T1D) in patients with significantly improved β-cell function. This study was designed to investigate the potential immunological mechanisms involved.Design and methods: 18 newly-diagnosed T1D were divided into two groups, the AHSCT group and the insulin therapy group. Blood mononuclear cells (PBMCs) of the patients at the baseli...

Multiple endocrine neoplasia type 1 (MEN1) is an inherited tumour syndrome characterized by the development of tumours of the parathyroid, anterior pituitary and pancreatic islets, etc. Heterozygous germ line mutations of MEN1 gene are responsible for the onset of MEN1. Here We reported totally 87 patients from 24 unrelated Chinese families associated with MEN1 and identified five novel mutations and several previously reported mutations. Furthermore, we detected a loss of het...

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting reproductive women. Treatments with Chinese herbal mixtures (HM) and electro-acupuncture (EA) have been proven efficient in clinic. This study evaluated the peripheral and central effects of HM and EA in dihydrotestosterone (DHT)-induced PCOS rats. The female Wistar rats were divided into control (C), control with placebo (CP), DHT-induced PCOS model (PCOS), PCOS model exposed to herbal mi...

Background/aims: Saxagliptin is a potent, selective dipeptidyl peptidase-4 (DPP-4) inhibitor, specifically designed for extended inhibition of the DPP-4 enzyme. Saxagliptin is cleared by both metabolism and renal excretion. The aims of this study were to determine the effect of renal impairment (RI) and haemodialysis (HD) on the pharmacokinetics of saxagliptin.Methods: This open-label, parallel-group study was conducted in subjects with normal renal func...

Background: Graves’ disease (GD) is an autoimmune disease caused by autoantibody targeting the thyrotropin receptor (TSHR) in the thyroid gland, resulting in hyperthyroidism with an annual incidence of 15 to 80/100,000 people worldwide. Current mainstream treatments for GD include aggressive treatment with radioiodine and thyroidectomy or unspecific immune-modulating therapy with glucocorticoids, antithyroid medications or anti-CD20 antibodies like Rituximab. Therefore, o...

Objective: Studies have demonstrated that patients with acromegaly have compromised bone health and an increased risk of vertebral fractures (VFs). However, the prevalence of VFs in Chinese patients with acromegaly has not been investigated by far. This study aimed to evaluate the prevalence and determinants of VFs in patients with acromegaly in a tertiary hospital in China.Methods: We enrolled patients diagnosed with acromegaly consecutively at West Chi...
