Objectives: To compare the levels of E2 in girls measured by LC-MS/MS and CLIA, and to evaluate the correlations between E2 levels and bone age, uterine length, and uterine volume.Methods: 133 newly diagnosed girls were selected. There were 80 girls in the ICPP group (44 in the Tanner II stage in the ICPP group, 36 in the Tanner III in the ICPP group), and 53 in the PT group， 40 healthy girls in the Tanner III gro...

Background: The relationship between probiotic supplementation and puberty onset has not been explored.Objective: To investigate the effects of probiotics oral intake during childhood on the gut microbiota when puberty onset in lactating female mice.Method: Feeding female mice with probiotic suspension of Bifidobacterium longum, Lactobacillus bulgaricus and Streptococcus thermophil...

Objective: To investigate the relevant prognostic factors and long-term safety of gonadotropin-releasing hormone analogs (GnRHa) in the treatment of idiopathic central precocious puberty (ICPP).Methods: This was a retrospective study. Data analysis included 142 girls with ICPP who reached final adult height (FAH). Among them, 101 girls were treated with GnRHa while 41 girls were untreated. The Pearson and Spearman correl...

Objectives: To compare the levels of estradiol (E2) in girls measured by liquid chromatography tandem-mass spectrometry (LC-MS/MS) and chemiluminescence immunoassay (CLIA), and to evaluate the correlations between E2 levels measured by the two methods and bone age, uterine length, and uterine volume. To explore the difference, consistency, and accuracy of LC-MS/MS and CLIA in determining E2 in girls with idiopathic central precocious puberty (ICPP), premature ...

Objective: To explore the therapeutic effects and adverse reactions of a combination of letrozole or Gonadotropin releasing hormone analog (GnRHa) and recombinant human growth hormone (rhGH), compared with rhGH alone, in pubertal short boys.Methods: Sixty-four pubertal short boys were divided into three groups, one group were treated with rhGH (rhGH group, n=21), one group were treated with the combination o...

Background: Tamoxifen is a selective estrogen receptor modulator，administrated in girls with precocious puberty such as McCune-Albright syndrome.Objective: To explore the effect of tamoxifen on the linear growth of precocious pubertal female rats.Method: At 16-22 day of age, 16 precocious pubertal female rats(induced by 300 μg danazol s.c. at 5-day old), were randomized...

Background: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy (MDPL) syndrome is a genetic disorder which was first recognized in 2010. MDPL syndrome is comprised of mandibular hypoplasia, deafness, progeroid features, lipodystrophy, hypogonadism and metabolic disorders. It is caused by an autosomal dominant mutation in the polymerase delta 1 (POLD1) gene, with <30 genetically confirmed cases to date.Cas...

Objective: To know more about the etiology and mechanism of antibody-negative diabetes, screening MODY pathogenicity genes and deepening understanding of islet autoantibody-negative diabetes, so as to individualized precision treatment.Methods: A total of 31 subjects with diabetes who had negative islet autoantibodies and C-peptide ≥0.3 ng/ml were collected. Another group was the type 1 diabetes control group, After informed consent obtained patien...

Objective: To explore the value of continuous hemodiafiltration in rescuing children with severe diabetic ketoacidosis.Method: Two children with severe diabetic ketoacidosis were studied in regard to clinical manifestation, laboratory examination and treatment and of the relevant literature was reviewed.Result: Case 1 was a girl of 13 years 5 months old, who was diagnosed as ‘Type 1 diabetes mellitus, Diabetic ketoacidosis and...

Objective: To screen and identify serum differentially expressed proteins in girls with rapidly progressing central precocious puberty and healthy girls by proteomics. Methods: 15 idiopathic central precocious puberty girls and 15 healthy children were admitted to the Children’s Hospital of Suzhou University from August 2017 to October 2018.After mixing in the group, the high-abundance protein was removed and quantified ...
