【摘要】 目的:观察妊娠期糖尿病患者外周血中Th1/Th2细胞及相关细胞因子表达水平的变化。方法:选择在笔者所在医院就诊的50例妊娠期糖尿病患者为观察组,50例健康妊娠的孕妇为对照组,收集观察组和对照组产妇的外周血,通过流式细胞术分析Th1/Th2细胞比例,采用ELISA检测白细胞介素-2(IL-2)、白细胞介素-4(IL-4)、白细胞介素-10(IL-10)、干扰素-γ(IFN-γ)的表达水平。结果:观察组患者外周血中Th1/Th2细胞的比例高于对照组,差异有统计学意义(P<0.05);观察组患者外周血中IL-2、IFN-γ的表达水平高于对照组,IL-4、IL-10的表达水平低于对照组,差异均有统计学意义(P<0.05)。结论:妊娠期糖尿病患者外周血中Th1/Th2细胞比例失衡,Th1细胞因子表达升高,Th2细胞因子表达降低,Th1/Th2免疫平衡的改变可能是妊娠期糖尿病免疫诊断和干预的新靶点,为妊娠期糖尿病的治疗提供试验依据。

Changes of Th1 / Th2 Cells and Related Cytokines Expression in Peripheral Blood of Gestational Diabetes Mellitus/HE Keren, WANG Shan, YU Jinghui, SHAN Lili, CHEN Huina. //Chinese and Foreign Medical Research, 2020, 18(19): -68
[Abstract] Objective: To observe the expression of Th1/Th2 cells and related cytokines in the peripheral blood of patients with gestational diabetes mellitus. Method: Totally 50 cases of gestational diabetes in our hospital were selected as the observation group and 50 cases of healthy pregnant women as the control group. The peripheral blood of the observation group and the control group were collected. The proportion of Th1/Th2 cells was analyzed by flow cytometry. The levels of IL-2, IL-4, IL-10, IFN-γ were detected by ELISA The level of expression. Result: The proportion of Th1/Th2 cells in the peripheral blood of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05). The expression level of IL-2 and IFN-γ in the peripheral blood of the observation group were higher than those of the control group, and the expression level of IL-4 and IL-10 were lower than those of the control group, the differences were statistically significant (P<0.05). Conclusion: The imbalance of Th1/Th2 cell proportion, the increase of Th1 cytokine expression and the decrease of Th2 cytokine expression in the peripheral blood of patients with gestational diabetes mellitus may be the new target of immunodiagnosis and intervention of gestational diabetes mellitus, and provide experimental basis for the treatment of gestational diabetes mellitus.

妊娠期糖尿病(gestational diabetes mellitus,GDM)是妊娠階段常见的并发症之一,多发生于妊娠中晚期,表现为妊娠后首次发现葡萄糖耐量异常,容易引发患者出现产科并发症,危及母体和胎儿的生命健康[1]。研究显示,GDM的发生可能和遗传因素、代谢紊乱、胰岛素抵抗、妊娠激素和免疫反应等相关,探索其具体发病机制和治疗策略仍是当前亟待解决的科学难题[2]。辅助性T细胞是机体免疫系统的重要组成成分,可分为Th1、Th2等多种亚群,对体液免疫和细胞免疫均有重要的调节作用[3]。吕芳等[4]研究发现GDM患者外周血中IL-6和TNF-α表达增多,其变化与胰岛素抵抗呈正相关,提示免疫功能改变可能参与GDM病理过程。本研究对GDM患者外周血中的Th1/Th2细胞及相关细胞因子水平的变化进行研究,探讨Th1/Th2细胞平衡在GDM中的作用及可能的机制,为GDM的防治提供理论依据。
