Impact of Bisphenol-A on the Puberty of Female Rats

Linqi Chen

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...

Comparative of serum estradiol levels in girls with different types of precocious puberty by liquid chromatography tandem-mass spectrometry and chemiluminescence immunoassay method

Chen Linqi , Shen Xinyi

Objectives: To compare the levels of E2 in girls measured by LC-MS/MS and CLIA, and to evaluate the correlations between E2 levels and bone age, uterine length, and uterine volume.Methods: 133 newly diagnosed girls were selected. There were 80 girls in the ICPP group (44 in the Tanner II stage in the ICPP group, 36 in the Tanner III in the ICPP group), and 53 in the PT group, 40 healthy girls in the Tanner III gro...

Comparative of serum estradiol levels in girls with different types of precocious puberty by liquid chromatography tandem-mass spectrometry and chemiluminescence immunoassay method

Chen Linqi , Shen Xinyi

Objectives: To compare the levels of estradiol (E2) in girls measured by liquid chromatography tandem-mass spectrometry (LC-MS/MS) and chemiluminescence immunoassay (CLIA), and to evaluate the correlations between E2 levels measured by the two methods and bone age, uterine length, and uterine volume. To explore the difference, consistency, and accuracy of LC-MS/MS and CLIA in determining E2 in girls with idiopathic central precocious puberty (ICPP), premature ...

Impact of Different Doses of Bisphenol-A on the Puberty of Female Rats

Linqi Chen , Fan Yang , Meifang Jin

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/...

Heterozygous Null Mutations in FLNB as a Cause of apparent isolated Short Stature in Chinese Children

Chen Ting , Zhou Huiting , Chen Linqi

Background: FLNB encodes filamin B (FLNB), a protein expressed in human growth plate chondrocytes, building the cytoskeleton that gives structure to cells and allows them to change shape and move. Biallelic loss-of-function mutations in FLNB result in spondylocarpotarsal synostosis (SCT; OMIM: 272460), while heterozygous null mutations related isolated short stature (ISS) have not been well described previously.Objective:</strong...

Clinical observation of post-menarche in idiopathic central precocious puberty or rapidly progressive puberty treated by GnRHa and GnRHa+rhGH

Chen PingPing , Chen Linqi , Wu Haiying

Objective: To investigate the clinical efficacy of GnRHa in the treatment of girls with post-menarche in ICPP or rapidly progressive puberty(RPP). To analyze the effect of GnRHa combined with rhGH on growth velocity (GV) and predicted adult height (PAH) in the process of GnRHa treatment with too low growth velocity.Methods: Retrospective analysis of the clinical data of 55 post-menarche ICPP/RPP girls withi...

A New Case of Thyroid Hormone Resistance α Caused by a Mutation of THRA/TRa1

Chen Linqi , Sun Hui , Chen Xiuli , Chen Ting

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...

Chen LinQi , Zhang Dandan , Wang Xiaoyan , Xie Rongrong , Wu Haiying

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...
