目的 探讨GDM孕早、中期脂肪细胞因子Chemerin、RBP4水平的变化。方法 采用前瞻性研究,测定38例GDM及40例正常孕妇孕早、中期血清Chemerin、RBP4水平,分析其与胰岛素抵抗的相关性。结果 GDM组孕妇孕早、中期血清Chemerin、RBP4水平及HOMA-IR均较对照组升高,差异有统计学意义(P<0.05);两组孕妇孕中期血清Chemerin、RBP4水平均较孕早期升高,差异有统计学意义 (P<0.05);Chemerin、RBP4水平与IR成正相关,差异有统计学意义(P<0.05)。结论 GDM孕妇孕早、中期脂肪细胞因子Chemerin、RBP4水平升高,Chemerin、RBP4水平的升高与IR有一定相关性。
Objective To discuss the serum levels of the Adipokine Chemerin、RBP4 of Gestational Diabetes Mellitus(GDM) in early pregnancy and middle pregnancy. Methods In prospective study, pregnant women, venous blood was collected from 40 controls and 38 GDM during early pregnancy (9-12weeks)and middle pregnancy (22-26weeks). Serum insulin, Chemerin, RBP4 were measured by enzyme-linked immunosorbent assay (ELISA). Results Mean serum levelsof Chemerin and RBP4 were significantly higher among GDM cases compared with controls during early pregnancy and middle pregnancy(P<0.05). In two groups, Mean serum levels of Chemerin and RBP4 in middle pregnancy were significantly higher than those in early pregnancy (P<0.05).During early pregnancy and middle pregnancy, the Chemerin and RBP4 levels were positively related with HOMA-IR (P＜0.05). Conclusion There is evidence of a positive association elevated Chemerin and RBP4 concentration of early pregnancy and middle pregnancy with increased GDM risk.
目的 探讨高龄妊娠期糖尿病（GDM）产妇糖耐量的特点及其与妊娠结局的关系。方法 选择2020年1月1日—2024年12月31日在广州市第一人民医院规律产检并分娩的高龄产妇727例，包括高龄初产妇226例（GDM 78例）和高龄经产妇501例（GDM 131例），按照75 g OGTT血糖异常项数进行分组：一项血糖异常产妇为GDM I组（高龄初产妇38例，高龄经产妇68例）；两项血糖异常产妇为GDM Ⅱ组（高龄初产妇26例，高龄经产妇51例）；三项血糖异常产妇为GDM Ⅲ组（高龄初产妇14例，高龄经产妇12例）；75 g OGTT正常高龄产妇为对照组。收集研究对象一般资料、75g OGTT血糖及相关妊娠结局进行分析比较。结果 高龄初产妇GDM发生率（34.51%）较高龄经产妇GDM发生率（26.15%）高，差异具有统计学意义（P=0.021）；高龄初产妇GDM Ⅲ型宫内感染（28.57%）、产后出血（14.29%）发生率最高，差异具有统计学意义（P=0.037、0.039）；高龄初产妇GDM I型早产（23.68%）发生率最高，差异具有统计学意义（P=0.013）。高龄初产妇及经产妇GDM Ⅱ型的羊水过多、甲状腺功能减退、宫内感染、早产发生率均呈上升趋势。结论 高龄妊娠糖尿病产妇随OGTT血糖异常项增多出现不良妊娠结局风险升高，其中高龄初产妇的早产、宫内感染及产后出血的发生率更高，因此，针对高龄初产妇，应更加注重孕期血糖及健康管理，以减少不良妊娠结局的发生。
Objective To analyze glucose tolerance characteristics in elderly pregnant women with gestational diabetes mellitus（GDM）and relationship with pregnancy outcomes．Methods From January 1，2020，and December 31，2024，727 elderly pregnant women who underwent routine prenatal examinations and delivered in Guangzhou First People’s Hospital were recruit．Among them，226 were elderly primiparas and 501 were elderly multiparas．GDM was diagnosed in 78 elderly primiparas and 131 elderly multiparas．Based on the results of the 75 g oral glucose tolerance test（OGTT），GDM cases were classified as follows：GDM I（one abnormal glucose value；38 elderly primiparas，68 elderly multiparas），GDM II（two abnormal values；26 elderly primiparas，51 elderly multiparas），and GDM Ⅲ（three abnormal values；14 elderly primiparas，12 elderly multiparas）．Elderly pregnant women with normal OGTT results served as the control group．General clinical data and pregnancy outcomes were collected．The prevalence and characteristics of GDM in elderly primiparas and multiparas were analyzed．Results The incidence of GDM was significantly higher in elderly primiparas than in elderly multiparas（P=0.021）．The incidence of intrauterine infection and postpartum hemorrhage was highest in elderly primiparas with GDM Ⅲ（P=0.037，0.039）．The incidence of preterm birth was highest in elderly primiparas with GDM I（P=0.013）．The incidence of polyhydramnios，hypothyroidism，intrauterine infection，and preterm birth showed an increasing trend in both elderly primiparas and multiparas with GDM II．Conclusions Elderly primiparas with more severe glucose tolerance abnormalities are at a higher risk of adverse pregnancy outcomes．Enhanced blood glucose monitoring and comprehensive health management during pregnancy are crucial for reducing the incidence of adverse outcomes in this population．
