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...

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...

Background: —Floating-Harbor syndrome(FHS) is a rare autosomal dominant genetic disorder associated with heterozygous mutations in SRCAP gene. The SRCAP protein activates the cAMP-response element binding protein-binding protein(CREBBP) gene that is involved in the regulation of cell growth and division.Objective: To report on long-term follow-up data of a boy with FHSMethods:...

Aldosterone synthase deficiency (ASD) is a rare autosomal recessive disease caused by inactivating mutation in the CYP11B2 gene, usually presenting with severe salt-wasting in infancy or stress-induced hyperkalaemia and postural hypotension in adulthood. ASD is unable to be detected by Neonatal screening of 17-hydroxyprogesterone, hence patients would not be diagnosed until they suffer from salt-wasting crisis. Due to this potentially life-threatening risk, early detection and...

Background: Nephrotic syndrome is the most common cause of kidney disease in children, but its pathogenesis remains unclear. Nephrotic syndrome in patients with congenital adrenal hyperplasia has not been reported.Case presentation: A 38-month-old female child was admitted with eyelid edema. She was the first child (birth weight, 3.0 kg, full term) of non-consanguineous parents of Chinese Han ethnicit. She had been diagnosed with congenital adrenal hyper...

Background: Congenital adrenal hyperplasia due to 17α-hydroxylase deficiency is a rare autosomal recessive disorder, characterized by sexual infantilism, amenorrhoea, hypertension and hypokalemia,which is caused by CYP17A1 gene mutations.Objective and hypotheses: To provide a descriptive analysis of 17α-hydroxylase deficiency in two female siblings with different karyotype of 46, XX and 46, XY.Method: The clinical feature...

Objective: In order to investigate the effect of precocity and gonadotropin-releasing hormone analogists (GnRHa) GnRHa treatment on glucose metabolism in female rats, the possible mechanism was studied through the changes of leptin, estrogen, growth hormone, insulin-like growth factor 1 and insulin receptor signal crosslinking pathway.Methods: Forty-eight 2-day-old female Sprague-Dawley (SD) suckers were randomly divided...

Research Objectives: Studies have shown that Akkermansiella mucinophila has a positive effect in various metabolic diseases, and can also prevent the onset of spontaneous type 1 diabetic NOD mice. However, its effect on type 1 diabetic mice is not clear. The purpose of this study is to analyze the effect of Akkermansiella mucinophila intervention on type 1 diabetic mice.Research Methods: Thirty male C57BL / 6 mice aged 3...

Objective: To explore the genetic basis for a Chinese three-generations pedigree affected with Severe Short Stature with a mild form of Geleophysic Dysplasia Type 2（GD2）Methods: We collected 11 related family members from a Chinese 3-generation pedigree with severe short stature with a mild form of Geleophysic Dysplasia Type 2 GD2. Clinical data of the 11 family members was collected．With genomic DNA...

Objective: To study the clinical characteristics of 46XX male syndrome case with negative SRYMethods: To summarize the characteristics of one case of SRY negative 46XX male syndromeResults: a 12-year-old boy came to our clinic for "breast development for one year". At the age of 1 year old, karyotype was done with the result of 46XX for hypospadias (penile-scrotal type). At...
