Objective: Decline in the number of D2 receptor (D2R) is considered as the reason of resistance to dopamine agonists (DA). PP4R2 gene was observed up-regulated in prolactinoma patients according to our previous genechip study. In this study, we demonstrated that PP4C was crucial for D2R expression and PRL secretion in rat pituitary MMQ cells.Methods: In this study, we used rat pituitary MMQ cells which could secrete abundant prolactin and express functio...

Despite numerous educational interventions and medical efforts efforts, modern society continues to suffer from obesity and its associated metabolic diseases, such as type 2 diabetes mellitus, and these diseases show little sign of abating. The brain, and in particular the hypothalamus, continues to gain attention as an important central target for the treatment of metabolic disease. However, most of the pharmaceutical approaches directly targeting the brain largely have faile...

Introduction: Thyroid dysfunction is one of the commonest endocrine disorders with hypothyroidism being the most common thyroid dysfunction in the elderly population[1]. An elderly patient with thyroid dysfunction can be asymptomatic, or present with non-specific symptoms, making biochemical testing of thyroid function useful and essential. We reviewed the screening rate and prevalence of thyroid dysfunction in older medical patient patients admitted to an Irish sec...

The sonic hedgehog (shh) pathway is known to be essential for pituitary development but little is known of its role in adult pituitary. Patched1, encoded by the Patched1 (Ptch1) gene, is a receptor for shh expressed in all cell types of the anterior pituitary. Adult onset hypogonadotropic hypogonadism has been reported in a genetically engineered mouse line with deletion of Ptch1 using S100a4 promoter driven CRE recombinase expression which is restri...

BackgroundAcute intermittent porphyria (AIP), a rare autosomal-dominant inherited disorder, caused by pathogenic mutations in the gene encoding porphobilinogen deaminase (PBGD). To explore its clinical characteristics, we investigated three patients with AIP admitted to our hospital.MethodsIn this study, patients successfully diagnosed with AIP and treated at the First Hospital of Shanxi Medical University si...

BackgroundThe reported HMBS mutations of acute intermittent porphyria(AIP) have been increasing gradually in China. We aim to explore its mutation characteristic in China and improve the understanding of its molecular heterogeneity.Material/methodsWe searched the literature about Chinese AIP patients with HMBS mutation in the PubMed, CNKI, Wanfang and CQVIP database, and 3 AIP patients with HMBS mutation in o...

Section 1: Case history: We present a case of a 75-year-old male with hypopituitarism on the background of recent COVID-19 infection. The patient was COVID-19 swab positive six weeks prior and suffered mild hypoxia, however declined hospital admission at that time. He presented one month later with sudden onset severe headache associated with fever; drowsiness and abdominal pain. He was discharged with antibiotics for suspected diverticulitis. His GP subsequently performed a p...

Background: Antihyperglycermic drugs have been linked to new-onset atrial fibrillation (NAF); however, the effect of different class antihyperglycermic drugs on the development of NAF in elderly patients with diabetes millitus (DM) has not been well studied.Objectives: We investigated the association between different class antihyperglycermic drugs and NAF in elderly patients.Methods: This was a retrospective cohort study performed...

Thyroid cancer is the most prevalent cancer among endocrine malignancies. In clinically, surgical resection combined with radioactive iodine therapy has been proved effective in treating differentiated thyroid cancer, including papillary and follicular thyroid cancers (FTC). However, patients with incurable differentiated thyroid cancer (DTC), poorly differentiated thyroid cancer (PDTC) and anaplastic thyroid cancer (ATC) exhibit worse prognosis. Therefore, a novel and effecti...
