Background: Familial hCG syndrome is a rare and benign cause of elevated serum beta human chorionic gonadotropin (β- hCG), moreover, elevated β-hCG in cerebrospinal fluid(CSF) has never been reported in familial hCG syndrome.Object: To report the two Chinese families of familial hCG syndrome with elevated β-hCG concurrently in blood/CSF.Method: We described the clini...

Quantitative analysis of endogenous and exogenous steroid hormones is an important step for our understanding of the causes of endocrine disorders in pediatric. In this study, we developed a method to simultaneously quantify endogenous and exogenous steroids in pediatric urine and plasma. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to simultaneously quantify steroid hormones in children plasma and urine. Under the optimum conditions, th...

Objective: To establish INS-1 cell iron overload model, and study the effect on iron overload, proliferation, insulin secretion, mitochondria defect and oxidative stress change.Methods: INS-1 cells were cultured with different concentrations (0 as control and 5, 10, 20, 40, 80,160,320µmol/L respectively) of ferric ammonium citrate (FAC). Labile iron pool (LIP) were calculated by detecting calcein-AM fluorescence ...

Aims: To evaluate the performance of a factory-calibrated flash glucose monitoring system in children with diabetes compared to venous blood glucose (BG).Methods: A total of 13 hospitalized participants newly diagnosed with type 1 diabetes, aged 1~14 years old, were involved in the study. Sensor glucose measurements on days 2, 3, 6, 7, 12 and 13 of wear were compared with venous BG. During these days, the venous BG ...

Purpose: To evaluate the efficacy of supervised Artificial Neural Network (sANN) in bone age assessment and compare the diagnostic performance of sANN-based TW3 skeletal maturity assessment on hand radiographs with that of experienced child endocrinologists.Materials and methods: This study developed an optimized artificial intelligence TW3 bone age assessment system by using the sANN and rating for the 20 hand bones (13RUS+7carpal) from A to I. 8332 of ...

Objective: To investigate the clinical features and genetic characteristics of HRAS-associated Costello Syndrome.Method: Characteristics of clinical data and gene mutation of two cases Costello Syndrome in XX hospital were retrospectively analyzed. The related literature was searched by using search terms ‘HRAS’ or ‘Costello Syndrome’.Result: Both patients were presented with mental retardation, growth retardati...

Patients who suffer from congenital hypopituitarism display a wide spectrum of phenotypes including pituitary hormone deficiencies and, in some cases, additional extrapituitary manifestations depending on the causative gene. A group of genes underlying hypopituitarism has been identified, yet several of them remain unknown. Here, we identified compound heterozygous variants in the TBC1D32 gene, c.1165_1166dupGT, p.(Gln390Phefs*32) and c.2151delA, p.(Lys717Asnfs*29) in...

Background: We want to know the clinical presentation and genetic mutation of congenital hyperinsulinism (CHI) patients in our country.Objective and hypotheses: To investigate the clinical outcomes and gene mutations related to CHI in our patients.Method: We studied the therapeutic outcomes of 95 cases of CHI and analyzed the associations between gene mutations and clinical features in 55 cases.Results: Among...

Several observational studies have reported vitamin D deficiency (VDD) in children with type 1 diabetes mellitus (T1DM). The investigation of VDD in children with new onset T1DM in China is lacking. The current study aimed to assess vitamin D status and examine the factors that influence VDD in children with new onset T1DM in Henan Province, China. Children with new onset T1DM (n=280) and healthy controls (n=710) were enrolled in Henan Province. Demographic a...

Objective: Patients with Turner syndrome (TS) have an increased risk of aortic dilatation (AD), which is associated with higher mortality. The diagnosis of AD in children is more difficult than that in adults. This study aimed to investigate the application of cardiovascular assessment criteria in diagnosing AD in Chinese children and adolescents with TS.Methods: In this retrospective study, a comprehensive cardiovascula...
