Introduction: To investigate the protective effects of combined intervention with adenovirus vector mediated interleukin 10 (IL10) and IGF1 genes on islet β cells in nonobese diabetes (NOD) mice with type 1 diabetes mellitus (T1D) at early stage.Methods: Twenty-four female NOD mice at onset of diabetes and aged 17–20 weeks old were randomly divided into four groups. Mouse 1, 2, and 3 groups were i.p. injected 0.1 ml of Ad-mIGF1, Ad-mIL10, and c...

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...

Background: Turner syndrome (TS) is due to complete or partial deletion of an X chromosome. The most common clinical features encountered in TS patients were short stature and primary amenorrhea.Objective and hypotheses: The purpose of this study was to investigate the causes of short stature in TS.Method: 86 patients with TS were diagnosed by karyotypes from 2004 to 2013, the karyotypes distribution were as follows: 64 patients wi...

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 ...

Background: Metformin is the only oral antihyperglycaemic agent (AHA) approved for use in youths with type 2 diabetes mellitus (T2DM). It may also be used to treat other conditions such as hyperinsulinaemia, pre-diabetes, and polycystic ovarian syndrome (PCOS). Therefore, an assessment of the prevalence of T2DM in the paediatric population based on the utilisations for metformin may overestimate the burden of the disease. However, metformin utilisation patterns in youths remai...

Background: Since metformin (MET), approved for treatment of type 2 diabetes (T2D), is the most commonly used oral anti-hyperglycaemic agent in youths MET prescriptions (Rx) could be used as a proxy for T2D burden in these populations. However, the extent of off-label use of MET in paediatrics is not well studied.Objective and hypotheses: Estimate the annual prevalence of ≥1 MET Rx among youths and calculate proportions with concomitant diagnoses o...

Background: Studies about the genetics of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency congenital adrenal hyperplasia (CAH) in Chinese children are less.Objective and hypotheses: Study the genotypes of Chinese probands with salt-wasting form of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency (CAH) and performed pedigree-based linkage analysis.Method: We have performed genetic-testing (Method...

Objective: To explore the genetic basis for a Chinese three-generations pedigree affected with Severe Short Stature with a mild form of Geleophysic Dysplasia Type 2（GD2）Methods: We collected 11 related family members from a Chinese 3-generation pedigree with severe short stature with a mild form of Geleophysic Dysplasia Type 2 GD2. Clinical data of the 11 family members was collected．With genomic DNA...

Objective: To study the clinical characteristics of 46XX male syndrome case with negative SRYMethods: To summarize the characteristics of one case of SRY negative 46XX male syndromeResults: a 12-year-old boy came to our clinic for "breast development for one year". At the age of 1 year old, karyotype was done with the result of 46XX for hypospadias (penile-scrotal type). At...

Objective: To recognize Schimke immune-osseous dysplasia from a case of spinal epiphyseal dysplasia.Method: Summarize the characteristics of one case of Schimke immune-ossesous dysplasia, and increase awareness of this disease.Result: The patient, male, with non-consanguineous parents, was born on May 8, 2012. He was hospitalized in our hospital in January 2020 due to his short stature for more tha...
