Background: Hypothalamic hamartoma (HH) is the most common cause of organic central precocious puberty (CPP). Gonadotropin-releasing hormone analogue (GnRHa) is widely used in the treatment of HH combined with CPP, but there is no report on the medium-and long-term efficacy and safety of HH in China.Objective: To investigate the medium-and long-term efficacy and safety of GnRHa in the treatment of children with CPP cause...

Study on the Mechanism of Metformin in Improving PGRN-Induced Insulin Resistance of 3T3-L1 Cell

Huang Siqi , Liang Liyang , Meng Zhe , Zhang Lina , Hou Lele , Liu Zulin , Chen Hongshan

To investigate the effect of metformin on the PERK-eIF2a pathway in PGRN - induced insulin - resistant cell model. METHODS: The 3T3-L1 Insulin-resistance cell model was constructed by dexamethasone and PGRN. Metformin was used to act on the cell model to screen out the optimal concentration group for reducing PGRN,The experiment was divided into the normal control group, dexamethasone group, and PGRN group. 4-PBA and metformin were used to act respectively.Western Blot was use...

Extending the Phenotype and Genotype of Okur–Chung Neurodevelopmental Syndrome

Meng Zhe , Liang Liyang , Huang Siqi , Liu Zulin , Hou Lele , Zhang Lina

Background: okur-chung neurodevelopmental syndrome was confirmed to be associated with developmental disorders attributed to germline CSNK2A1 pathogenic missense variants. Only 26 cases and 22 kinds of genotype have been reported in the world so far. All reports highlighted the recognizable facial features of the syndrome as well as frequently occurring clinical features including neurodevelopmental delay, short stature, gastrointestinal, musculoskeletal and i...

A Mitophagic Response to iron Overload-Induced Oxidative Damage Associated with the PINK1/Parkin Pathway in Pancreatic Beta Cells

ZHANG Lina , LIANG Liyang , LIU Zulin , HOU Lele , OU Hui , HUANG Siqi

An increased iron overload led to a disorder in glucose metabolism. However, the mechanism through which iron overload induces beta cell death remains unknown. The present study revealed that ferric ammonium citrate treatment inhibited cell viability in vitro, induced a decline in mitochondrial membrane potential, increased oxidative stress and activated mitophagy. These effects could be alleviated by a reactive oxygen species scavenger. In summary, we demonstrated th...

Analysis of Phenotypes and Genotypes in 84 Patients with 21-hydroxylase Deficiency

Hou Lele , Lin Shaofen , Meng Zhe , Ou Hui , Liu Zulin , Zhang Lina , Jiang Zhuannan , Liang Liyang

Background and Aims: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by impaired cortisol synthesis. 21-hydroxylase deficiency (21-OHD) caused by mutations in CYP21A2 gene is the most common form of CAH. This study aims to analyze the phenotype-genotype correlation and the characteristics of gene mutation frequency of 21-OHD patients in China, helping to provide evidence for clinical practice and genetic counseling of 21-OHD patie...
