Background: Prader–Willi syndrome (PWS) is a rare genetic disorder associated with hyperphagia, and excessive weight gain. Patients with PWS are at elevated risk of developing morbid obesity and associated life-threatening complications. Although gut microbiota has been suggested to play a role in disease phenotypes, little is known about its composition and how it relates to hyperphagia.Objective: The aim of this ...

Keywords: growth hormone, small for gestational age, genetic defects; Silver-Russell syndrome; growth hormone deficiencyObjectives: To evaluate the influencing factors of GH treatment in Chinese short stature children born SGA.Methods: This was a single-center, retrospective, cross-sectional survey in China. Of 101 patients were identified born SGA and 66 short stature children bor...

Keywords: Sleep-Related Breathing Disorders, recombinant human Growth Hormone treatment, Prader–Willi syndrome, Toddlers.Background: Recombinant human growth hormone (rhGH) therapy is beneficial for children with Prader–Willi syndrome (PWS) in improving short stature and metabolism, but the effect of early rhGH treatment on respiratory and sleep parameters for the PWS children under three years old remains el...

Background: MODY can be mistaken for Diabetes type 1 or type 2.Objective: To evaluate genetic background in 22 patients presented with diabetes, negative islet cell antibodies, normal C-peptide and positive family history of diabetes. Genetic testing was done at Invitae laboratory and evaluated 28 genes for diagnosis of MODY.Results: Patients were divided into 2 groups: Group 1 wit...

Case report: 14 yrs. old Hispanic girl was referred for evaluation of diabetes (Hb A1c 9.8 %) and morbid obesity BMI 36 kg/m2. She developed acanthosis nigricans, elevated triglycerides (TG) 1162 mg/dl, low HDL 34 mg/dl, fatty liver with elevated AST 84 U/l, ALT 103 U/L. The abdominal sonogram revealed significant hepatomegaly with moderate steatosis. Her islet cell AB were negative, C-peptide 3.11 ng/ml was normal. She has a strong family history of diabetes:...

Objective: 21-hydroxylase deficiency (21-OHD) is the most common cause of congenital adrenal hyperplasia due to CYP21A2 gene mutation. The aim of study is to expand CYP21A2 mutational spectrum in the Chinese population and to provide novel genetic information in terms of ethnic diversity.Methods: 95 Chinese suspected 21-OHD patients with phenotypes varying from salt-wasting (SW) to nonclassic symptoms w...

Background: Simple obese is a worldwide public health problem. Recent studies suggested a possible relationship between obese and vitamin D deficiency.Objective and hypotheses: To discuss the relationship between 25-Hdroxyvitamin D with glucose and lipid metabolism of simple obese in Chinese children.Method: 65 children with obeses (35 mild-to-moderate, 50 severe) and sixty-two children with normal weight were enrolled in this tria...

Background: Permanent neonatal diabetes mellitus (PNDM) is a rare form of monogenic diabetes with onset less than 6 months of age. Together, activating mutations in KCNJ11 and ABCC8 genes, that encode the Kir6.2 andsulfonylurea receptor 1 (SUR1) subunits, respectively, account for nearly 50% of PNDM cases.Case report: We present a case reported a child diagnosed with PNDM resulting from a new mutation in the insulin (INS) gene, leading to severe hypergly...

Background: Fibroblast growth factor receptor 3 (FGFR3) is a negative regulator of skeletal development. Gain-of-function point mutations in FGFR3 are responsible for hypochondroplasia (HCH), one of the most common forms of dwarfism in humans. Autophagy is an evolutionarily conserved catabolic process, which is indispensable for cell homeostasis maintenance and stress responses. Dysregulation at the level of autophagic activity consequently disturbs the chondr...

Type 1 diabetes mellitus is autoimmune T cells mediated destruction of β-cells. Mesenchymal stem cells (MSCs) are considered a promising treatment for T1DM due to the strong immunosuppressive and regenerative capacity. However, the comprehensive mechanism is still unclear. Our previous study indicated that the transforming growth factor beta-induced gene (TGFBI) is highly expressed in human umbilical cord derived mesenchymal stem cells (hUC-MSCs), which is also implicated...
