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...

Ferritin is a widely used iron storage indicator. At the same time, it is also viewed as an indicator of inflammation. Chronic low-grade inflammation in obese individual, especially in the one with metabolic disorders, related to comorbidities and poor prognosis. Both hyperglycemia and iron overload can induce inflammation and result in vascular endothelial dysfunction. To study the role of ferritin in obese children and its impact on artery and liver, the present study invest...

Background: Pseudohypoparathyroidism 1A (PHP1A) is a rare disease caused by mutations of GNAS gene, and characterized by Albright's hereditary osteodystrophy (AHO) and resistance to multiple hormones. Infantile onset is often missing diagnosed due to atypical clinical manifestations. This study aims to summarize the clinical and genetic characteristics of child onset PHP1A patients.Methods: 12 patients were ...

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...

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...

Turner syndrome is associated with insulin resistance, increased incidence of type II diabetes, and hypertension, all of which are cardiovascular risk factors. The purpose of this study was to evaluate the lipid profile of Chinese girls with untreated Turner syndrome, (aged 2 to 15 years; 50.9% 45,XO) and age-matched, normal girls. A total of 108 girls with Turner syndrome and 99 normal girls had lipid profile measurements, including cholesterol, triglycerides,high-density lip...

Objective: To identify genetic mutations of a pedigree affected by severe short stature in Chinese populations for the first time.Methods: Auxological and endocrinological profiles were measured. Targeted next-generation sequencing (NGS) analyses comprising 277 shorted stature-associated candidate genes and 19 related copy number variation (CNV) regions were used to identify gene mutations in the proband. Three web-based software programs (SIFT, PolyPhen...

Objective: This paper is aimed to explore the significance of plasma kisspeptin level in diagnosis and therapeutic evaluation through the detection of kisspeption level of girls diagnosed with idiopathic central precocious puberty (ICPP) before treatment and after 6-months of treatment and girls with simple premature thelarche (PT).Methods: A total of 70 girls including 24 girls diagnosed with ICPP, 21 girls with PT and 25 normal girls were enrolled. ELI...

Early puberty is associated with obesity in young girls and has physical, psychosocial, and reproductive implications. In adults and children, MRI evidence of cellular inflammation in the mediobasal hypothalamus (MBH gliosis) is seen in obesity, and its anatomic location overlaps with key neuronal populations controlling reproduction, fertility, and feeding. We sought to assess whether MRI evidence of MBH gliosis associates with pubertal development in girls and if that differ...

Background: Familial hCG syndrome is a rare and benign cause of elevated serum beta human chorionic gonadotropin (β- hCG), moreover, elevated β-hCG in cerebrospinal fluid(CSF) has never been reported in familial hCG syndrome.Object: To report the two Chinese families of familial hCG syndrome with elevated β-hCG concurrently in blood/CSF.Method: We described the clini...
