Background: Studies about the genetics of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency congenital adrenal hyperplasia (CAH) in Chinese children are less.Objective and hypotheses: Study the genotypes of Chinese probands with salt-wasting form of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency (CAH) and performed pedigree-based linkage analysis.Method: We have performed genetic-testing (Method...

Key words: KBG syndrome, ANKRD11, zebrafish, CRISPR/CasRx, Wnt signaling pathwayBackground: KBG syndrome (KBGS) is a rare condition caused by variant in ANKRD11 gene, which is characterized by intellectual disability, distinctive facial features, macrodontia of the upper central incisors, skeletal anomalies and short stature. Patients carrying loss-of-function ANKRD11 variants exhibit short stature due to defects of bone develop...

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...

Purpose: The causes of obesity is so much that the pandemic spread the global. The inherited factors have a profound effect on body fat mass, as well as the environmental factors. Out of these, the foremost is genetic factors that tend to early childhood obesity. The consensus recommended that genetic testing is necessary for serious early onset obesity to identify the pathogenic genes of inherited obesity. In order to improve the positive rate of genetic test...

Objective: This study aimed to investigate the therapeutic effects of recombinant human GH (rhGH) combined with low-dose stanozolol on the growth and final adult height (FAH) of girls with Turner syndrome (TS).Method: A total of 47 girls with TS were treated with rhGH (47.6–52.4 μg/kg per day) and low-dose stanozolol (20–35 μg/kg per day), starting at a mean age of 12.57±1.96 year. The control group consisted of 26 girls with TS,...

Background: Aromatase inhibitors (AIS) can block the conversion of androgens to estrogens, thus can be used to delay bone maturation in males, however, the effect on improvement of final adult height (FAH) is still controversial.Objective and hypotheses: A prospective study was performed to evaluate the effect of letrozole used on the FAH in males with idiopathic short stature (ISS).Method: 55 boys with ISS and had entered puberty ...

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...

Background: McCune-Albright Syndrome(MAS）includes fibrous dysplasia(FD), cafe-au-lait spots and gonadotropin-independent precocious puberty(PP). Adenohypophyseal hyperfunction syndromes is uncommon but may be potentially severe complication.Objective: To report a girl who has been confirmed McCune-Albright syndrome and has been found pituitary adenoma during follow-up.Methods:</stron...

Objective: To find the roles of Fetuin-A and FGF21 in metabolic disorders through investigating the correlations between Fetuin-A, FGF21 with metabolic indicators in girls with Turner syndrome (TS).Methods: A cross-sectional study of TS girls ranging from 5 to18 years and age-, body mass index (BMI)- matched healthy girls were recruited from the outpatients in Fuzhou Children’s Hospital of Fujian Medical University...
