Objective: To investigate the etiology and clinical features of Chinese children with PAI.Method: 427 children (age 0–18 years) with PAI followed at our institution between September 1989 and March 2016 were studied.Results: 1. 228 males and 199 female (1.14:1) were included. Median age at diagnosis was 1.66 (10th–90th, 0.06~8.73 yrs.2. An identified diagnosis(clinical or genetic) was obtained in 93...

Background: The hypothalamus-pituitary-gonad (HPG) axis is crutial to the development and function of reproductive system. Gonadotropin-releasing hormone (GnRH) has been the standard test for the assessment of activation of HPG axis. Because GnRH is no longer available, GnRH analogues (GnRHa) are now used. In previous studies, GnRHa stimulation tests have been the mainstay for establishing the diagnosis of precocious puberty in female and distinguishing constitutional delay of...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is reported inadequate growth and impairment of the final height (FH).Objective: We present the results of near FH in 55 patients with classic 21-OHD followed up for approximately 11.6 years(the longest 25.3 years)in a single institution, and the variables related to NFH.Method: Patients with classic 21-OHD followed up at our clinic, who had ...

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: We aim to investigate the association among progranulin (PGRN), high-mobility group box 1 (HMGB1), and obesity related markers in young rat model of high fat diet-induced obesity.Materials and Methods: 20 Male Sprague-Dawley (SD) rats at the age of 21 days were divided into two groups randomly. The rats were fed with normal diet (NC group) or high-fat diet (OB group). The NC group and OB group were sacrificed ...

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...

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...

Objective: We sought to evaluate the role of long-term HRT on the lipid profile and glucose metabolism in girls with TS.Design: A pre-test/post-test observational study.Seting: Pediatric TS clinic in The First Affiated Hospital, Sun Yat-sen University.Patients: 56 girls with TS had accurate maintenance HRT data....

Objective: To understand the clinical characteristics, etiological distribution and related metabolic problems of children with premature pubarche.Methods: The clinical data of 55 cases of premature pubarche were summarized. All the children were tested by ACTH stimulation test and GnRHa stimulation test, of which 17 cases were detected by CYP21A2 gene,and 16 cases of Premature Adrenarche (PA) and 14 cases of Isolated Pr...

An 11-year-old boy came to our hospital on 2019-1-23 because of "discovered hypercalcemia for 4 months."Past History: The child has a history of lupus nephritis for 2 years, and currently oral prednisone 12.5mg qd, mycophenolic acid 0.25g q12h, tacrolimus 1mg q12h for treatment. The lupus activity index was reviewed once a month due to lupus nephritis. At present, SLEDAI (lupus activity score) is 2 points, and the condition is we...
