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...

Background: Now in many causes of precocious puberty, thinking of environmental endocrine disruptors (EDCs) is one of the causes. Bisphenol A (BPA), as a kind of environmental endocrine disruptors, can interfere with normal endocrine activities. But up to now, there is few reports of the influence of BPA in premature thelarche (PT) of below 2 years girls.Objective and hypotheses: To investigate the association between BPA and premature thelarche in 6 mon...

Objective: To investigate the early predictors of serum IGF-1, DHEAS, AMH and BMP-6 in rapidly progressive puberty girls.Methods: 750 cases of central precocious puberty(CPP), early puberty(EP) and rapidly progressive puberty(RPP) in Children's hospital of Soochow university were recruited from August 2017 to December 2018. After follow-up six months to one year, 138 girls were divided into CPP(n=32), EP...

Objective: To screen and identify serum differentially expressed proteins in girls with rapidly progressing central precocious puberty and healthy girls by proteomics. Methods: 15 idiopathic central precocious puberty girls and 15 healthy children were admitted to the Children’s Hospital of Suzhou University from August 2017 to October 2018.After mixing in the group, the high-abundance protein was removed and quantified ...

Background: 5α - reductase type 2 deficiency (5αRD) is an autosomal recessive hereditary disease which has an incidence of 11.2%–15.5% among population with 46, XY DSD (disorders of sex development).Objective: To study the growth pattern in Chinese pediatric patients with 5αRD.Subjects: Data were from 187 patients with 5αRD (age from 0–16 years old,with homozygous or compound heterozygous mutations in ...

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...

Objective: To observe vaginal opening day (VOD), hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression level changes in neonatal rats exposure to different doses of bisphenol-A(BPA).Methods: Neonatal female SD rats were randomly divided into six groups: control group, vehicle group, 17β-estradiol group (17β-estradiol, E2,10 μg/kg per day), low-dose BPA group (25 μg/kg per day), medium-dose BPA group (50 μg/...

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...
