研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

(1)病例对照研究妊娠期糖尿病(GDM)和非GDM子代脐带血CBMC端粒系统变化 (2)通过基础实验在不同葡萄糖浓度下对脐带血CBMC体外培养,检测葡萄糖浓度变化如何影响细胞氧化应激状态、细胞端粒损伤情况、端粒结构/端粒酶基因启动子区域甲基化状态的变化,并阐述机制。  

Objectives of Study:

(1) Case-control study of gestational diabetes mellitus (GDM) and changes in CBMC telomere system in umbilical cord blood of non-GDM offspring (2) Umbilical cord blood CBMC was cultured in vitro at different glucose concentrations through basic experiments to detect how changes in glucose concentration affect the oxidative stress state of cells, the damage of cell telomeres, the change of telomere structure/telomerase gene promoter region methylation state, and elaborate the mechanism.
