Background: Bartter syndrome (BS) and Gitelman syndrome (GS) have similar clinical manifestations. It’s hard to be distinguished by the symptoms and laboratory, even though the genetic analysis cannot identify them precisely. The precise diagnoses associate with the right treatment and prognosis. Hypercalciuria usually involved with neonate type Bartter syndrome, and hypomagnesemia with Gitelman syndrome.Objective a...

Background: SRS is a typical epigenetic disease. Approximately 40% of patients can not be detected genetic and epigenetic disturbances.Objective and hypotheses: To analysis whether there is unknown genes or imprinted genes associated with pathogenicity of SRS and to detect the fine mapping SRS hypomethylation position through the Illumina Methylation 450K chip to detect genome-wide methylation differences.Method: To detect genome-w...

Background: Nearly half of SRS epigenetic etiology is unknown. Effect of GH in SRS is not exact.Objective: To determine novel gene or imprinted gene associated with pathogenicity of Silver–Russell syndrome (SRS) through detection genome-wide methylation differences. To observe GH efficacy in SRS and the relationship between GH and epigenetic changes.Method: To detect genome-wide methylation site through the Illumina 450K methy...

Background: BMI has a negative impact on spontaneous and stimulated GH secretion in children, but the impact of BMI and free fatty acids (FFA) on peak stimulated GH values in Han children with short stature is unknown.Objective and hypotheses: To assess the effects of BMI and FFA on peak GH values in Han children with short stature.Method: This was a retrospective, cross-sectional study. We used arginine–clonidine test to anal...

Background: Adolescent growth spurt is the fast and intense increase in the rate of growth in height and weight that occurs during the adolescent stage of the human life cycle.Objective and hypotheses: To investigate the changes of hormone levels and body composition in pubertal children with growth retardation.Method: A non-randomised clinical controlled study was conducted in 208 cases (males 122, 10–14 years and females 86,...

Aims: To evaluate the performance of a factory-calibrated flash glucose monitoring system in children with diabetes compared to venous blood glucose (BG).Methods: A total of 13 hospitalized participants newly diagnosed with type 1 diabetes, aged 1~14 years old, were involved in the study. Sensor glucose measurements on days 2, 3, 6, 7, 12 and 13 of wear were compared with venous BG. During these days, the venous BG ...

Objective: To explore the clinical features and the genetic cause of a multiple malformation patient with short stature.Methods: The clinical data was collected in Beijing Children’s Hospital in November 2017. The disease-causing variant was identified using exome sequencing and confirmed with Sanger sequencing. Related literature was searched from Wanfang and Pubmed databases using the key word of ‘PORCN gene’ to identify the clinical fea...

Backgrounds: The treatment of diazoxide-unresponsive congenital hyperinsulinism (CHI) is a big challenge in clinical practice. Octreotide is an off-lable medicine for CHI but widely used nowadays. However, the efficacy and adverse effects have been reported varied in centers.Objective: To evaluate the efficacy and safety of the subcutaneous octreotide injection for diazoxide-unresponsive CHI in China.Subjects and methods: Diazoxide...

Background: We want to know the clinical presentation and genetic mutation of congenital hyperinsulinism (CHI) patients in our country.Objective and hypotheses: To investigate the clinical outcomes and gene mutations related to CHI in our patients.Method: We studied the therapeutic outcomes of 95 cases of CHI and analyzed the associations between gene mutations and clinical features in 55 cases.Results: Among...

Background: 5α - reductase type 2 deficiency (5αRD) is an autosomal recessive hereditary disease which has an incidence of 11.2%–15.5% among population with 46, XY DSD (disorders of sex development).Objective: To study the growth pattern in Chinese pediatric patients with 5αRD.Subjects: Data were from 187 patients with 5αRD (age from 0–16 years old,with homozygous or compound heterozygous mutations in ...
