Background: It remains unclear whether specimen repeated freeze-thaw cycles can influence urinary lutenising hormone (LH) and follicular stimulating hormone (FSH) assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen repeated freeze-thaw cycles on urinary LH and FSH determined by ICMA.Method: The first morning-voided urine was collected and divided two parts. One part was s...

Background: It remains unclear whether specimen pH can influence urinary LH and FSH assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen pH on urinary LH and FSH assayed by ICMA.Method: The first morning-voided urine were collected and divided into 11 samples (each 100 ml). The urine pH was determined with a pH meter. Hydrochloric acid and sodium hydroxide were added to al...

Purpose: This study aimed to profile children diagnosed with hypercalcemia of different etiologies at a single center.Method: We retrospectively reviewed 13 children diagnosed with hypercalcemia of different etiologies.Results: We describe 13 pediatric cases, aged 4 months to 12 years old (median age: 8 months), diagnosed from 2018 to 2021. Six males and seven females were included...

Objective: PWS is a rare genetic imprinting disorder resulting from the expression loss of genes on the paternally inherited chromosome 15q11-13. Early-onset life-thriving obesity and hyperphagia represent the clinical hallmarks of PWS. The noncoding RNA gene SNORD116 within the minimal PWS genetic lesion plays a critical role in the pathogenesis of the syndrome.Methods: We collected inguinal white adipose tissues (ingWA...

Objective: Serum Anti-Mullerian Hormone (AMH) and Inhibin-B (INHB) levels were assessed in patients with Turner Syndrome (TS) of different karyotypes, and ovarian reserve function was evaluated by AMH and INHB in patients with TS.Methods: From January 2021 to January 2024, 52 patients diagnosed with TS aged 4-17 years were diagnosed in the Department of Endocrinology, Genetics and Metabolism of Jiangxi Provincial Childre...

Objective: To analyze the correlation between glucose metabolism disorder and bone turnover markers in obese adolescents.Methods: From June 2022 to June 2023, 50 obese adolescents in West China Second Hospital of Sichuan University were taken as the research group, and 50 adolescents with normal weight who received health examination at the same time were taken as the control group. The general data, glucose metabolism i...

Objective: X-linked agammaglobulinemia (XLA) is a kind of primary immunodeficiency disease caused by mutations in the gene encoding Bruton agammaglobulinemia tyrosine kinase (BTK). This study, we identified a novel in frame deletion mutation in exon11, c.902 _ c.904 delAAG(p.e301 _ g302 delinsG) in BTK gene and evaluated the function of BTK.Methods: A five-year-old boy presented with recurrent respiratory tract infections. His height wa...

Background: Turner syndrome (TS) is caused by complete or partial of the second sex chromosome and characterized bygrowth failure, primary ovarian failure, the constellation of the lymphedema sequence, characteristic facial features, left-sided cardiac anomalies, renal anomaly, and skeletal anomalies. Among all of the associated traits, cardiovascular abnormalities are common in TS and an important cause of early mortality. Hence, our aim is to investigate the...

Background: Genome-wide association studies have identified rs314276, rs314263, rs7759938 and rs314280 in or near the LIN28B gene as associated with age at menarche. To date, the effect of polymorphisms in this gene on idiopathic central precocious puberty (ICPP) in Chinese girls have not been reported.Objective and hypotheses: The aim of this study was to evaluate the association of the four loci with ICCP in Chinese girls.Method:...
