Intact steroid hormone biosynthesis is essential for growth and development of the human fetus and embryo. In the present study, gas chromatography-mass spectrometry was employed to characterize the steroidal milieu in amniotic fluid (n=65; male: female = 35: 30) of mid-gestation (median: 18.8th week, range: 16.0th – 24.6th week) by a comprehensive targeted steroid hormone metabolomics approach. The levels of 52 steroids i...

Introduction: Complex and ordered intracellular signal pathways play a significant role in sex determination in mammals, mediating the balance of gonadal development. A major pathway involved in the regulation of the male development is mitogen-activated protein kinase (MAPK) signaling pathway. To date, mutations of MAP3K1 gene have been found to account for approximately 15%-20% of 46, XY gonadal dysgenesis (46, XY GD)....

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...

The amniotic fluid (AF) milieu is complex and essential to fetal well-being. Here we present a new LC-MS/MS method for the targeted metabolomics analysis of 20 unconjugated and conjugated steroids in 65 AF samples during mid-gestation. Sample preparation included protein precipitation, centrifugation, solid phase extraction and derivatization. We measured progesterone (Prog), 17α-hydroxyprogesterone (17OHProg), testosterone (T), estrone (E1), estradiol (E2), estriol (E3),...

Objective: To observe and analyze the efficacy and safety of autologous stem cell transplantation (AHSCT) in children with type 1 diabetes.Methods: Twelve children were enrolled in our study who were newly diagnosed as type 1 diabetes in Children’s Hospital of Fudan University from Sep 2009 to Dec 2011. Changes in the exogenous insulin requirement were observed and HbA1C and C peptide level were measured before and after AHSCT.<p class="abstext"...

Objective: To evaluate the effect of Ziyin Xiehuo granules (ZYXH) and Zishen Qinggan granules (ZQ7G) on partial precocious puberty (PPP).Methods: The present study was a multicenter, randomized, single-blinded, positive-controlled trial. A total of 143 patients were assigned to either the ZYXH group or the ZQ7G group using a random number table. The ZYXH group received ZYXH three times daily for 6 months, while the ZQ7G group received ZQ7G three times da...

Objective: To investigate the clinical and molecular characteristics of a girl with 17α hydroxylase/17,20-lyase deficiency, of which, onset was as rhabdomyolysis and hypokalemia. And then we identified the functional consequences of two novel CYP17A1 mutations.Materials and Methods: A 11 years old girl, 46,XX karyotypes, presented with rhabdomyolysis, hypokalemia and hypertension. She had elevated levels of plasma adrenocorticotropic hormone, serum ...

Background: The incidence of 11β-hydroxylase deficiency is quite low in China, less is reported about the gene mutation in Chinese population.Objective and hypotheses: To analyze the clinical features and CYP11B1 gene mutations of a family with 11β-hydroxylase deficiency (11β-OHD) and literature review were also included.Method: Physical examination and laboratory tests were done on a 4 years old girl and gene mutati...

Background: IDF-2007 MS definition (MS-IDF2007) for children and adolescents has been challenged frequently in clinical practice and should be improved further. Therefore, it becomes imminent to explore an accessible and effective tool to screen obese children with the metabolic syndrome components.Objective and hypotheses: To investigate the optimal cut-off values and compare the accuracy for the triglycerides and HDL cholesterol ratio and homeostasis m...

Background: The hypothalamic–pituitary–adrenal (HPA) axis, and cortisol in particular, has been reported to be involved in obesity-associated metabolic disturbances in adults and in specific populations of adolescents.Objective and hypotheses: To investigate the associations between serum ACTH and cortisol levels and cardiovascular risk factors in obese children and adolescents.Method: Of 1119 obese children and adolescen...
