We have examined a female child patient aged about 3 years and 8months old to confirm the diagnosis of Schmid metaphyseal chondrodysplasia (SMCD) at the Genetics out-patient department, Children's Hospital Affiliated to Zhengzhou University. The child was diagnosed with the abnormal phenotypic characteristics who showed short-limbed dwarfism, bowed legs, waddling gait and genu varum. Based on the child's family history, during the early stages, the child was misdiagnos...

Background: Previous studies have speculated that melatonin secreted by the pineal gland plays a role in the regulation of puberty, and pineal cyst may affect its secretory function, thus causing early pubertal development. However, there are few studies on early pubertal development with pineal cyst and its clinical features are not clear. This study aims to explore its clinical features and the relationship with cyst size to further improve the understanding...

Purpose: Identify CYP21A2 gene variants in pediatric patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency from Henan, China, and to analyze genotype-phenotype correlations. We also analyze the relationship between the clinically effective dosage of hydrocortisone and CYP21A2 genotype.Materials/Methods:A total of 214 21-OHD children were recruited in Henan children's hospital from 2008 to 202...

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...

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: To explore the influencing factors of girls with rapidly progressive puberty(RPP), to construct a risk prediction model of RPP in girls, to investigate the value of serum IGFBP-2, Irisin and Ghrelin in prediction of RPP in girls.Methods: 1. Construction and verification of the prediction model for girls with rapidly progressive puberty. The girls who visited the Department of Endocrinology, Children's Hos...

Background: Short stature is clearly not a disease, but is commonly perceived to be associated with social and psychological disadvantage.Objective and hypotheses: To evaluate the psychological changes in children with short stature after growth hormone therapy.Method: One hundred and thirty children aged 6–14 years old were diagnosed as short stature (ISS and GHD). And they were divided into intervention group (55 children) a...

Background: It is now widely accepted that chemical pollutants in the environment can interfere with the endocrine system. The impact of endocrine disrupting chemicals on puberty disorders is concerned. bisphenol-A (BPA) has been measured in fetal plasma. There are different toxic effects with different doses of BPA.Objective and hypotheses: To observe vaginal opening day (VOD), hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression...

The action of Thyroid hormone (T3) is mediated by the binding to nuclear receptors (TRa1, TRα1/2), which are ligand dependent transcription factors, encoded by the THRA and THRB genes. THRA germline mutations cause a rare genetic disease called resistance to thyroid hormone α (RTHα) first reported in 2012 . Only 20 missense and frameshift mutations have been reported to date, From this small group of patients, and analysis of animal models, it emerges that the d...

Background: Anti-Müllerian hormone (AMH) and inhibin B (INHB) are two hormones investigated as markers of ovarian reserve in female. serum AMH and INHB levels change through the progression of puberty, and might be markers for identifying pubertal progression rate in girls.Objective and hypotheses: To invetigate serum AMH and INHB levels as markers of pubertal progression rate in girls with central precocious puberty (CPP).Met...
