Maternal virilization and female fetal pseudohermaphroditism caused by exaggerating androgen secretion of pregnancy leutomas

Chen C , Wang Y

Objective: Maternal and female fetal virilization is subject to exaggerating androgen secretion of pregnancy luteomas which is associated with the protective capacity of placenta safeguard against hormone conversion and presents with variable extent of female pesudohermapharotidism as exposure in critical gestational stage.Patient(s): A nulligravida woman suffering from bilateral hydronephrosis and recurrent acute pyelonephritis caused by bilateral solid...

Comparison of plasma osteoprotegerin and related factors in two groups of pregnant women

Song A. , Nie M. , Wang Y. , Sun M.

Objective: The aim of the present study was to determine the plasma osteoprotegerin (OPG) levels in women with gestational diabetes mellitus (GDM) and normal glucose tolerance (NGT) during the last trimester of pregnancy, and to investigate the relationship between OPG and some related factors.Method: In this study, 65 women with GDM and 65 women with NGT were enrolled. Plasma concentration of OPG was measured by enzyme linked immunosorbent assay (ELISA)...

Vitamin E and selenium have a protective role in apoptosis induced by H2O2 in human thyrocytes

Yan S. , Shi S. , Wang Y. , Yu X. , Wang L.

Objective: To investigate the influence of vitamin E (VE) and selenium (Se) on apoptosis of human thyrocyte induced by H2O2.Methods: The human thyroid epithelium cells (TEC) from normal para-adenoma tissues of patients with thyroid adenoma resection were cultured. In prevention groups, vitamin E (50 μmol/l), selenium (10–7 mol/l) or serum-free medium was respectively added into thyrocytes of monolayer culture before H...

Six loci associated with high-density lipoprotein cholesterol or triglycerides in Chinese pregnant women

Nie M. , Wang Y. , Li W. , Ping F. , Gao J. , Liu J.

Background: The serum concentrations of lipoproteins and lipids are heritable risk factors for cardiovascular disease. Pregnancy is associated with increases in plasma lipid profiles. Identifying the genetic determinants could provide novel insights into mechanisms of dyslipidemia and reveal avenues for developing new therapies. The objective of this study was to investigate the impact of six single nucleotide polymorphisms (SNPs) on serum lipid levels during pregnancy.<p ...

Determinants of children’s iodine nutrition and epidemiological features of children’s goiter and nodule in iodine-excessive areas

Lv S. , Xu D. , Wang Y. , Du Y. , Jia L. , Chong Z. , Ma J. , Zhao J.

Introduction: Excessive iodine intake can cause iodine overnutrition, goiter and other thyroid disease. This study is to probe the determinants of children’s iodine nutrition and their goitrous and nodular prevalence in areas with excessive iodine in drinking water in Hebei province of China. Methods Three townships were selected by simple random sampling among the 8 townships with median water iodine being 200–300 μg/l in Hengshui prefecture of Hebei province. ...

Diabetic ketoacidosis at diagnosis influences complete remission after treatment of hematopoietic stem cell transplantation in adolescents with type 1 diabetes

Gu W. , Hu J. , Zhu D. , Tang W. , Li L. , Cui W. , Hong J. , Zhang Y. , Wang W. , Ning G.

Objective: To determine if autologous nonmyeloablative hematopoietic stem cell transplantation (AHSCT) was worthwhile to do in type 1 diabetes adolescents with diabetic ketoacidosis at diagnosis.Research Design and Methods: We enrolled 28 type 1 diabetes patients aged 14–30 years in a prospective AHSCT phase II clinical trial. Hematopoietic stem cells were harvested from the peripheral blood following a pretreatment consisting of a combination of cy...

Repression of NR5A nuclear receptors by SUMO and DEAD-box proteins

Wang Y , Sampathkumar Y , Peiris DN , Manan RA , Lebedeva LA , Suzawa M , Wadekar SA , Desclozeaux M , Ingraham HA , Lee MB

The Nuclear Receptor Subfamily 5A member, Steroidogenic Factor 1 (SF-1, Ad4BP, NR5A1), is critical for steroidogenesis, stress responses, sexual differentiation and body weight regulation in mice. Patients with rare mutations in SF-1 have confirmed its role in male sexual differentiation and adrenal response to physiological stress in humans. In contrast, Liver Receptor Homologue 1 (LRH-1, FTF, CPF, NR5A2) is involved in endoderm development, bile acid and lipid metabolism and...

The effects of BPA exposure on fat mass and serum leptin concentrations have no impact on bone mineral densities in non-obese premenopausal women.

Liu J. , Zhao H. , Bi Y. , Ma L. , Zhang L. , Zhao L. , Tao B. , Sun L. , Wang T. , Zhao Y. , Wang W. , Xu M. , Chen J. , Ning G.

Objective: Bisphenol A (BPA) exposure may promote obesity, but its effect on bone mineral density (BMD) has not been reported in humans. In the present study, we aimed to examine the complex interplay between BPA exposure, fat mass, fat-free mass, serum estradiol, leptin, osteocalcin levels and BMDs in a group of premenopausal women.Methods: A total of 246 Chinese premenopausal women aged 20 years and older with regular menstrual cycles were investigated...

Genetic susceptibility, birth weight and obesity risk in young chinese

Shi J. , Hong J. , Qi L. , Cui B. , Gu W. , Zhang Y. , Li L. , Xu M. , Wang L. , Zhai Y. , Miao L. , Wang R. , Bi Y. , Wang W. , Ning G.

Thus far, approximately 30 loci influencing body mass index (BMI) and the risk of obesity have been identified. In this study, we aimed to examine the individual and joint associations of 23 BMI-associated loci identified from recent genome-wide association studies in Caucasians with obesity risk in young Chinese. Birth weight reflects prenatal metabolic adaption and has been related to later-life obesity risk. We particularly assessed whether these genetic variants interacted...
