Objective: To establish INS-1 cell iron overload model, and study the effect on proliferation, insulin-secretion and oxidative stress change.Methods: INS-1 cells were cultured in either normal or high glucose medium. Both groups were treated with different concentrations of (5, 10, 20, 40, 80 μmol/l respectively) of ferric ammonium citrate (FAC). Number and state of the cells were detected by trypan blue staining. Labile iron pool (LIP) were calcula...

Background: Abnormalities in glucose homeostasis are fairly common complications in thalassemia major (TM) patients. Previous studies had shown associations between some endocrinopathies and iron overload of the myocardium, liver as assessed by MRI techniques. This study aimed at determining the relationship among cardiac T2*, liver T2* and abnormal glucose in TM patients.Objective and hypotheses: A total of 34 (27 male) transfusion-dependent TM patients...

Background: Adrenoleukodystrophy (ALD) is a genetic disease associated with demyelination of the CNS, adrenal insufficiency, and accumulation of very long-chain fatty acids in tissue and body fluids.Objective: To research the clinical features, laboratory tests, imaging examinations and treatment on children who suffer from X-linked ALD. Also aim at revealing the correlation between the severity of disease and level of very long chain fatty acids (VLCFAs...

Objective: To explore the status and the main influencing factors of peripheral nerve conduction dysfunction in Chinese children and adolescents with type 1 diabetes mellitus (T1DM).Methods: Nerve electrophysiological indicators including amplitude, latency and conduction velocity of median nerve, ulnar nerve, superficial peroneal nerve, sural nerve, common peroneal nerve and tibial nerve were collected, and the results ...

Objective: To analyze the clinical features and causative genes in children with undiagnosed short stature and study the causative genes in our hospital. Methods Clinical manifestations, laboratory test and whole exome sequencing (WES) results of children with undiagnosed short stature who visited pediatric endocrinology department of our hospital from January 2018 to August 2019 were analyzed retrospectively. Causative genes were classified and analyzed accor...

Background: Hypothalamic hamartoma (HH) is the most common cause of organic central precocious puberty (CPP). Gonadotropin-releasing hormone analogue (GnRHa) is widely used in the treatment of HH combined with CPP, but there is no report on the medium-and long-term efficacy and safety of HH in China.Objective: To investigate the medium-and long-term efficacy and safety of GnRHa in the treatment of children with CPP cause...

To investigate the effect of metformin on the PERK-eIF2a pathway in PGRN - induced insulin - resistant cell model. METHODS: The 3T3-L1 Insulin-resistance cell model was constructed by dexamethasone and PGRN. Metformin was used to act on the cell model to screen out the optimal concentration group for reducing PGRN,The experiment was divided into the normal control group, dexamethasone group, and PGRN group. 4-PBA and metformin were used to act respectively.Western Blot was use...

Background and Aims: Geleophysic dysplasia (GD) and acromicric dysplasia (AD) are rare skeletal dysplasia belonging to the group of acromelic dysplasia and are both characterized by severe short stature, short hands and feet, stiff joints, facial anomalies and some radiological manifestations, including delayed bone age, shortened long tubular bones and ovoid vertebral bodies. Patients with GD clinically present the characteristic "happy" facial featur...

Objective: The functional status and influencing factors of pancreatic beta cells in patients with β-thalassemia major (β-TM) were investigated.Methods: A cross-sectional study was conducted in 88 patients with β-TM, with an average age of 11.3±5.6 years. Thirty-two healthy subjects were selected as the control group. FBG, FINS, HOMA-IRI, HMOA-ISIand HOMA-β FI were calculated between ...

Background: okur-chung neurodevelopmental syndrome was confirmed to be associated with developmental disorders attributed to germline CSNK2A1 pathogenic missense variants. Only 26 cases and 22 kinds of genotype have been reported in the world so far. All reports highlighted the recognizable facial features of the syndrome as well as frequently occurring clinical features including neurodevelopmental delay, short stature, gastrointestinal, musculoskeletal and i...
