Objective: We aim to investigate the association among progranulin (PGRN), high-mobility group box 1 (HMGB1), and obesity related markers in young rat model of high fat diet-induced obesity.Materials and Methods: 20 Male Sprague-Dawley (SD) rats at the age of 21 days were divided into two groups randomly. The rats were fed with normal diet (NC group) or high-fat diet (OB group). The NC group and OB group were sacrificed ...

Circulating Exosomal miRNAs involved in the Pathogenesis of Children Nonalcoholic Steatohepatitis.Background: The incidence of children non-alcoholic fatty liver disease (NAFLD) increased rapidly paralleled with the global burden of obesity and diabetes. Although most patients are nonalcoholic fatty liver, there are still a small part of them will progress to nonalcoholic steatohepatitis (NASH), fibrosis and cirrhosis. However, the diagnosis of NASH is b...

Prader-Willi syndrome (PWS) is a complex neurobehavioral disorder characterized by infantile significant hypotonia and feeding difficulties, followed by morbid obesity secondary to hyperphagia, short stature, functionally deficient gonads, intellectual disabilities and behavioral problems. It is caused by lack of expression of imprinting genes on the paternally inherited chromosome 15q11.2-q13 region. The genetic mechanism responsible for Prader-Willi syndrome can rarely be in...

Background: Melatonin is known to regulate a variety of biological processes. The investigation and application of melatonin in oral development have got a lot of attention. The study was performed to investigate the effects of melatonin on development of human dentin formation.Objective and hypotheses: To investigate the role of melatonin in proliferation and differentiation of human dental pulp cells(hDPCs).Method: HDPCs were obt...

Background: Rathke’s cleft cysts (RCC) are benign, epithelial lined cystic remnants of the craniopharyngeal duct, and are a common radiological differential for lesions involving the sellar and sellar/suprasellar region. RCC are not very common in children.Objective and hypotheses: To investigate the clinical characteristics of RCC in children.Method: A retrospective analysis was conducted in 24 patients with RCCs diagnosed be...

Background: Obesity in children and adolescents has become an increasing clinical and public health concern. It was reported that obesity is positively associated with sexual maturation in both boys and girls in China. However, the effect of obesity on pubertal development is incompletely elucidated.Objective and hypotheses: To evaluate the fat mass and body composition by dual-energy x-ray absorptiometry (DEXA) in Chinese precocious puberty girls, and t...

Introduction: Permanent neonatal diabetes mellitus (PNDM) is a rare disease which is defined as the onset of diabetes before the age of 6 months with persistence through life. Patients with KCNJ11 or ABCC8 gene mutations have the opportunity to switch to oral sulfonylurea therapy. There were limited studies about the genetic analysis and long-term follow-up of PNDM.Case report: We report four cases of this kind of PNDM, including their genetic mutations,...

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...

Background: Central precocious puberty (CPP) results from the premature pubertal activation of the hypothalamic-pituitary-gonadal axis before eight years for girls or nine years for boys. A systematic review and meta-analysis was conducted to evaluate the long-term efficacy and safety of leuprolide acetate (LA) 11.25mg 3-month formulation in children with CPP.Methods: A systematic search in PubMed and Embase was conducte...

Purpose: Identify CYP21A2 gene variants in pediatric patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency from Henan, China, and to analyze genotype-phenotype correlations. We also analyze the relationship between the clinically effective dosage of hydrocortisone and CYP21A2 genotype.Materials/Methods:A total of 214 21-OHD children were recruited in Henan children's hospital from 2008 to 202...
