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 and hypotheses: To evaluate the long-term efficacy of triptorelin 3.75 mg subcutaneously injection every 6 weeks on final height in girls with ICPP.Method: Forty females with ICPP received triptorelin 3.75 mg every 6 weeks subcutaneously injection and reached FAH were collected. These patients were divided into two groups. Group A: GnRHa alone, n=17; group B: triptorelin+rhGH, n=23. During the treatment, height, weight, annual...

Objectives: To describe safety and effectiveness of high (≥90-180 µg/kg) and low (<90-30 µg/kg) dose leuprorelin in treating central precocious puberty (CPP).Methods: In this observational, retrospective study, effectiveness was evaluated based on regression or no progression of Tanner staging as the primary outcomes. LH, FSH, estradiol or testosterone suppression, and decrease in bone age to chronolo...

Backgrounds: Maturity-onset diabetes of the young (MODY) is a cluster of early-onset, monogenic disorders which is inherited in autosomal dominant form. It is mainly caused by genetic defects in beta-cell, which results in beta-cell dysfunction. Till now, 14 MODY types specified by mutation in respective 14 genes with their etiologies are known. Among them, glucokinase (GCK) gene encodes glucokinase enzyme which plays a crucial role in the regulation of insuli...

Background: Exposure to per- and polyfluoroalkyl substances (PFASs) may interfere with thyroid function in the general population and disturb the timing of puberty onset.Objectives: We investigated the possible relationship between PFASs and thyroid hormone (THs) exposure in girls with central precocious puberty (CPP).Methods: In a prospective study initially established for assess...

We have examined a male child patient aged about 15 years old to confirm the diagnosis of adrenal hypoplasia congenital (AHC) at the Genetics in-patient department, Children's Hospital Affiliated to Zhengzhou University.When the child was 5 years and 9 months,he was diagnosed as abmormal phenotypic characteristics who had skin hyperpigmentation, penis enlargement, rapid growth over the past 2 years, along with fatigue, drowsiness, and pubic hair appearing for 2 months.Base...

Objective: To highlight conversion of hypothyroidism to hyperthyroidism by case reported and literatures reviewed.Methods: Case report and literature review.Results: Two children diagnosed as Hashimoto’s thyroiditis with hypothyroidism and treated with levothyrocine primary. During the following, hyperthyroidism was noted even the stop the administration of levothyrocine. thyroid receptor antibody (TRAb) was positive during th...

Introduction: To investigate the protective effects of combined intervention with adenovirus vector mediated interleukin 10 (IL-10) and insulin-like growth factor 1 (IGF1) genes on islet β cells in nonobese diabetes (NOD) mice with type 1 diabetes mellitus (T1D) at early stage.Methods: Twenty-four female NOD mice at onset of diabetes and aged 17–20 weeks old were randomly divided into four groups. Mouse 1, 2 and 3 groups were intraperitoneally ...

Background: To evaluate potential function of visfatin in SW872 adipocytes under the conditions which produce insulin resistance by free fatty acids (FFAs). Then to explore the mechanism of visfatin on the level of signal molecules.Objective and hypotheses: To evaluate the effects of visfatin on the mRNA expressions of the insulin signal molecules including insulin receptor substrate 1 (IRS1), IRS2, and phosphatidylinositol 3 kinase (PI3K) on the states ...

Context: Data and studies based on exome sequencing for the genetic evaluation of short stature are limited, and more large-scale studies are warranted. Some factors increase the likelihood of a monogenic cause of short stature, including severe short stature (<–3 standard deviation scores) and small for gestational age (SGA) without catch-up growth. However, whether these factors can serve as predictors of molecular diagnosis remains unknown.<p c...
