Background: Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder caused by the deficient production, secretion or action of gonadotropin-releasing hormone (GnRH), which is the master hormone regulating the reproductive axis. CHH can be divided into Kallmann syndrome (KS) with dysosmia and normosmic Congenital hypogonadotropic hypogonadism (nCHH) according to the presence or absence of an olfactory disorder.Methods:</...

Key words: precocious puberty; idiopathic central precocious puberty; premature thelarche; gut microbiota; HPG axisBackground: The incidence of precocious puberty and obesity has increased significantly after the COVID-19 epidemic, and the specific cause is not clear. There seems to be a causal relationship between obesity and idiopathic central precocious puberty. A few studies have shown that the changes of gut microbi...

Keywords: Central precocious puberty; Luteinizing hormone; Precocious puberty Gonadotropin-releasing hormone agnosit testBackground: 2019 International consensus on central precocious puberty (CPP) proposed that random serum luteinizing hormone (LH) ≥0.83IU/L and < 0.2IU/L has important reference value for the establishment or exclusion of CPP, but there is no corresponding diagnostic criteria in China. This study ...

Object: To assess the efficacy and impact factors of treatment with GnRHa alone or in combination with rhGH in idiopathic central precocious puberty (CPP) or early and fast puberty (EFP) in Chinese girls.Methods: We conducted a retrospective analysis on 20 years of data obtained from 11 medical centers from January 1998 to March 2017, and 393 girls with CPP (n=302) or EFP (n=91), who untreated or received GnRHa alone or in Combination w...

Background: Congenital hypothyroidism (CH) is a common endocrine disorder with a prevalence ranging from 1:2000 to 1:4000 newborns. The majority of CH cases were reported to be associated with mutations in several genes, which including the TSH receptor gene (TSHR).Objective and hypotheses: The aim of this study is to examine the frequency of TSHR gene mutations among CH patients in the Guangxi Zhuang Autonomous Region of China and to discover correlatio...

Objective: The aim here was to describe the characteristics of obese children and adolescents and to determine how the prevalence of comorbidities differed over 10 years in China.Methods: Obese children and adolescents were enrolled from Department of Endocrinology, Children’s Hospital of Zhejiang University School of Medicine in Hangzhou (Zhejiang Province, China). Eligibility was de&filig;ned by a body mass index ...

Background: Central precocious puberty is defined by the onset of breast development before the age of 8 year in girls. Approximately 90% of girls have an idiopathic formwithoutstructural central nervous system (CNS) abnormality. It is controversial that all girl with central precocious puberty (CPP) should undergo brain magnetic resonance imaging (MRI) for intracranial pathology.To evaluate the outcome of brain MRI in girls with CPP and to identify the cl...

Background: Turner syndrome (TS) is caused by complete or partial of the second sex chromosome and characterized bygrowth failure, primary ovarian failure, the constellation of the lymphedema sequence, characteristic facial features, left-sided cardiac anomalies, renal anomaly, and skeletal anomalies. Among all of the associated traits, cardiovascular abnormalities are common in TS and an important cause of early mortality. Hence, our aim is to investigate the...

Background: Mannose binding lectin (MBL) is an important innate immune molecule and is previously found to be related to artery damage in some diseases as SLE rheumatoid arthritis and severe atherosclerosis. However, its role in artery change is still contradictory according to different studies. We found the carotid intima–media thickness (CIMT) increased in obese children which indicated an early change of atherosclerosis.Objective and hypotheses:...

Background: Cardiovascular disease is one of the most prominent causes of mortality world widely. A key related factor of atherosclerotic cardiovascular disease is the presence of dyslipidemia. Together with elevated blood pressure, obesity, and diabetes mellitus, dyslipidemia is a component of metabolic syndrome and associated with an increasing incidence of coronary heart disease.Objective and hypotheses: The aim of this study was to investigate the co...
