GDF5 Increased White Adipose Tissue Thermogenesis Through p38 MAPK Signaling Pathway in Fatty Acid-binding Protein 4-GDF5 Transgenic Mice

LUO Feihong , ZHANG Wenting , PEI Zhou , WU Xiaohui

Growth differentiation factor 5 (GDF5) was reported to regulate brown adipogenesis, however, its effects on insulin sensitivity, full metabolic syndrome spectrum and the thermogenesis in subcutaneous white adipose tissue (sWAT) haven't been elucidated yet. We thus generated fatty acid-binding protein 4 (Fabp4)-GDF5 transgenic mice and showed that GDF5 transgenic mice developed a relative lean phenotype on a high-fat diet (HFD) and showed increased insulin sensitivity. Over...

Effect of Specimen Repeated Freeze-Thaw Cycles on Urinary Gonadotropin Determined by Immunochemiluminometric Assays

Ma Yaping , Xu Zhuangjian , Hu Yu , Zhu Wenying , Wang Qing

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...

Hou Lele , Lin Shaofen , Liu Zulin , Ou Hui , Zhang Lina , Huang Siqi , Meng Zhe , Liang Liyang

Objective: To analyze the clinical features and causative genes in children with undiagnosed short stature and study the causative genes in our hospital. Methods Clinical manifestations, laboratory test and whole exome sequencing (WES) results of children with undiagnosed short stature who visited pediatric endocrinology department of our hospital from January 2018 to August 2019 were analyzed retrospectively. Causative genes were classified and analyzed accor...

Medium-and long-term follow-up observation of the efficacy and safety of GnRHa in the treatment of five cases of central precocious puberty caused by hypothalamic hamartoma

Huang Siqi , Meng Zhe , Liu Zulin , Zhang Lina , Hou Lele , Ou Hui , Liang Liyang

Background: Hypothalamic hamartoma (HH) is the most common cause of organic central precocious puberty (CPP). Gonadotropin-releasing hormone analogue (GnRHa) is widely used in the treatment of HH combined with CPP, but there is no report on the medium-and long-term efficacy and safety of HH in China.Objective: To investigate the medium-and long-term efficacy and safety of GnRHa in the treatment of children with CPP cause...

Adenohypophyseal Hyperfuction in Childeren and Adolescents with McCune-Albright Syndrome

Xie Liu-lu , Li Yan-hong , Ma Hua-mei , Du Min-lian

Background: McCune-Albright Syndrome(MAS)is a rare disease caused by somatic gain-of-function mutations of the GNAS gene, presenting with fibrous dysplasia(FD), cafe-au-lait spots and gonadotropin-independent precocious puberty(PP). Adenohypophyseal hyperfunction syndromes is reported uncommon but potentially severe complication of MAS.Method: A prospective study was performed to evaluate the prevalence of the pit...

Analysis on the influencing factors of neonatal serum FT3, FT4 and TSH

Zhang Cong , Zheng Rongxiu , Ma Shifeng , Wu Chushan , Liu Xiaoxiao , Cheng Siqi , Zhao Yue , Jiang Haiyan

Background: With the increasing survival rate of extremely premature infants, neonatal thyroid dysfunction is more frequently observed clinically. Despite the guidelines, the timing of screening for neonatal thyroid function remains controversial, especially for premature infants. At present, there is no unified standard for serum FT3, FT4 and TSH levels of newborns of different gestational ages and postnatal days.Objective:</str...

Study on the Mechanism of Metformin in Improving PGRN-Induced Insulin Resistance of 3T3-L1 Cell

Huang Siqi , Liang Liyang , Meng Zhe , Zhang Lina , Hou Lele , Liu Zulin , Chen Hongshan

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...
