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...

Serum Uric Acid and Its Correlation with Metabolic Syndrome Factors in Simple Obesity Children

Liu Zulin , Liang Liyang , Meng Zhe , Hou Lele , Zhang Lina , Jiang Zhuannan

Objective: To study the relationship between serum uric acid (SUA) and metabolic syndrome (MS) factors in simple obesity children.Methods: Data of 70 simple obesity children (50 boys and 20 girls, ages 10.50±3.44) and 30 age- and sex-matched children (17 boys and 13 girls, ages 9.96±2.48) with normal body mass index (BMI) were studied. Anthropometrics, SUA, lipid profiles, glucose and insulin concentration were determined. The differences of pa...

Hemolysis in a Girl with Type 1 Diabetes Mellitus and Glucose-6-Phosphate Dehydrogenase Deficiency

Hou Lele , Lin Shaofen , Liang Liyang , Meng Zhe , Zhang Lina , Liu Zulin

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a X-linked enzymopathy. Hemolysis during type 1 diabetes mellitus (T1DM) treatment in patients with G6PD deficiency has been reported, but the underlying pathogenesis is not fully clarified.Objective and hypotheses: We try to explore the association between the two diseases.Method: We report a girl in whom hemolysis occurred after diabetic ketoacidosis (DKA) treatme...
