Comparison of the efficacy and safety of recombinant human growth hormone in treating idiopathic short stature and growth hormone deficiency in children.

Purpose: The present study aimed to compare the efficacy and safety of recombinant human growth hormone (rhGH) therapy between children with idiopathic short stature (ISS) and growth hormone deficiency (GHD).

Methods: A total of 150 pediatric patients with ISS and 153 pediatric patients with GHD who received rhGH treatment for more than one year from 2005 to 2016 were enrolled. Growth velocity (GV); height standard deviation (HtSD); insulin-like growth factor-1 standard deviation (IGF-1SD); body mass index (BMI); and the incidence of fasting hyperglycemia, fasting hyperinsulinemia, and hypothyroidism were recorded and compared.

The molecular mechanism of acylation stimulating protein regulation of adipophilin and perilipin expression: involvement of phosphoinositide 3-kinase and phospholipase C.

The novel adipokine acylation stimulating protein (ASP) is involved in lipid metabolism and obesity-related disorders. Adipophilin and perilipin, two members of the lipid droplet protein family, participate not only in fat storage within adipocytes, but also in ectopic lipid deposition in the form of cytoplasmic triglyceride (TG) droplets within many types of mammalian cells. During differentiation to mature adipocytes, mechanisms controlling the synthesis and turnover of these lipid droplet proteins are only partially understood, the mechanisms regulating gene/protein expression as yet unidentified.

[Effect of acylation stimulating protein on the perilipin and adipophilin expression during 3T3-L1 preadipocyte differentiation.].

Perilipin and adipophilin, two significant lipid droplet (LD)-specific proteins, participate in storing fat or ectopic lipid deposition and fat mobilization in many types of mammalian cells. Acylation stimulating protein (ASP) is a novel adipocyte-derived hormone known for a major determinant for triglyceride synthesis (TGS) and lipid metabolism. The present study was aimed to investigate: (1) whether ASP, rather than insulin, is a powerful potentiator which could physiologically and directly influence TGS during 3T3-L1 preadipocyte differentiation; (2) whether ASP exposure at indicated time points during 3T3-L1 preadipocyte differentiation could influence the gene/protein expression of adipophilin and perilipin.

[Clinical characteristics of Wolfram syndrome].

Objective: Wolfram syndrome (WFS) is a rare, autosomal recessive inherited disease characterized by various clinical manifestations. The aim of this study was to investigate clinical characteristics of WFS.

Methods: One case of WFS was reported.

[Effects of ghrelin on the proliferation and differentiation of 3T3-L1 preadipocytes and its possible mechanisms].

Objective: To investigate the effects of ghrelin on the proliferation and differentiation of 3T3-L1 preadipocyte, and study the possible mechanisms.

Methods: 3T3-L1 preadipocytes were cultured in vitro. The proliferation potentials of 3T3-L1 preadipocytes that were treated with different concentrations of ghrelin were evaluated by MTT methods.

Childhood gynecomastia: a clinical analysis of 240 cases.

Two hundred forty cases of childhood gynecomastia were studied retrospectively. There were 13 cases aged 3 to 10 years and 227 cases aged 11 to 15 years. Of the 240 cases of gynecomastia, 160 presented with bilateral breast enlargement, 50, left breast enlargement, and 30, right breast enlargement.

[Expression of Kiss-1 mRNA in the hypothalamus of true precocious female rats].

Objective: To investigate the gene expression of Kiss-1 in the hypothalamus of true precocious female rats at various stages of development.

Methods: Forty 5-day-old normal female Sprague-Dawley rats were randomly assigned into four groups of 10 rats: Control group 1, Control group 2, Model group 1 and Model group 2. The rats from the two model groups were injected with 300 microg of danazol at 5 days of age to induce true precocious puberty.

[Expression of Daxx in children with acute leukemia].

Objective: To investigate Daxx expression and its clinical significance in children with acute leukemia.

Methods: The expression of Daxx protein was detected by immunohistochemical assay in 50 children with newly diagnosed acute leukemia (34 cases of acute lymphocytic leukemia and 16 cases of acute non-lymphocytic leukemia). Twenty children with normal bone marrow were used as the control group.

Roles of adipocyte derived hormone adiponectin and resistin in insulin resistance of type 2 diabetes.

Aim: To detect plasma levels of new adipocyte derived hormone adiponectin and resistin in type 2 diabetes patients and to explore their potential roles in insulin resistance in type 2 diabetes.

Methods: According to the body mass index (BMI), 60 type 2 diabetes patients were divided into two groups, one group was non-obese diabetes patients with BMI<25Kg/M(2) (30 cases) and the other group was obese diabetes patients with BMI>25Kg/M(2) (30 cases). There were 28 healthy persons in the control group.

[Application of gas chromatography-mass spectrometry analysis on urine filter paper in the high-risk screening and diagnosis of inherited metabolic diseases].

Objective: To establish a specific procedure for the high-risk screening and diagnosis of organic acidurias and other inherited metabolic diseases in China.

Methods: A nation-wide network for the high-risk screening and diagnosis of genetic metabolic diseases was formed to facilitate the collaboration. Urine samples were collected using filter paper from patients with clinical symptoms suspicious of inherited metabolic diseases.
