【摘要】:目的:通过检测原因不明复发性流产(URSA)患者外周血和蜕膜组织中Th17、Th22细胞比例及白细胞介素-22(IL-22)水平,了解URSA患者外周血及蜕膜组织中Th17、Th22细胞比例及IL-22水平变化。 方法:选取2013年9月至2014年2月于广西医科大学第一附属医院就诊的原因不明复发性流产患者15例为研究组,,正常早孕要求人流(NP)的患者为对照组。于人流术前采集其肘静脉血5ml,人流术后留取蜕膜组织。通过流式细胞术和酶联免疫吸附实验(ELISA)检测其外周血及蜕膜组织中Th17、Th22细胞比例及IL-22水平。 结果:1、URSA组患者外周血及蜕膜组织Th17(CD4+IL-17+)细胞比例分别为1.62%±0.52%和2.11%±0.61%,均高于相应NP组患者1.24%±0.27%和1.47%±0.41%,,差异有统计学意义(P0.05)。并且蜕膜局部Th17细胞比例水平高于外周血,差异有统计学意义(P0.05)。 2、 URSA组患者外周血及蜕膜组织Th22细胞比例分别为1.59%±0.52%和1.91%±0.58%,均明显高于相应NP组患者1.11%±0.24%和1.33%±0.32%,,差异有统计学意义(P0.01)。并且蜕膜局部Th22细胞比例水平高于外周血,差异有统计学意义(P0.05)。 3、 URSA组患者外周血及蜕膜组织中IL-22水平分别是181.98±8.10pg/ml,198.52±10.98pg/ml,均高于对应NP组患者104.28±4.73pg/ml,110.47±6.43pg/ml,差异有统计学意义(P0.01)。并且蜕膜局部IL-22水平高于外周血,差异有统计学意义(P0.01)。 4、比较URSA组患者与NP组患者外周血及蜕膜组织中IL-22细胞因子水平与Th17细胞比例的相关性,其相关系数及P值分别为:外周血中(r=0.157, P0.05)、(r=0.437, P0.05);蜕膜中(r=0.069, P0.05)、(r=0.235,P0.05)。结果示两变量间线性关系极弱或无线性关系存在。 5、比较URSA组患者与NP组患者外周血及蜕膜组织中IL-22细胞因子水平与Th22细胞比例的相关性,其相关系数及P值分别为:外周血中(r=0.885,P0.05)、(r=0.749, P0.01);蜕膜中(r=0.849, P0.05)、(r=0.934,P0.01)。结果均呈正相关关系。 6、分别比较URSA组患者与NP组患者外周血与蜕膜组织中Th17细胞比例的相关性,其相关系数及P值分别为:(r=0.661, P0.01)、(r=0.954,P0.01)均呈正相关关系。 7、分别比较URSA组患者与NP组患者外周血与蜕膜组织中Th22细胞比例的相关性,其相关系数及P值分别为:(r=0.685, P0.01)、(r=0.943,P0.01),均呈正相关关系。 8、分别比较URSA组患者与NP组患者外周血与蜕膜组织中IL-22水平的相关性,其相关系数及P值分别为:(r=0.875, P0.01)、(r=0.823, P0.01)均呈正相关关系。 结论:1、妊娠妇女外周血及蜕膜组织中Th17、Th22细胞比例和IL-22水平增高与URSA的发生具有相关性;并且相较于外周血,局部蜕膜中Th17、Th22细胞比例和IL-22水平改变与妊娠状态有更密切的关系。 2、妊娠妇女(包括URSA患者)外周血与局部蜕膜的Th17、Th22细胞比例及IL-22水平改变呈平行改变。 3、外周血及蜕膜组织中Th17、Th22细胞比例及IL-22水平可能可以作为URSA的预测指标。
[Abstract]:Objective: to investigate the changes of Th17 Th22 cells and IL-22 levels in peripheral blood and decidua of patients with URSA by detecting the proportion of Th17 Th22 cells in peripheral blood and decidua tissues of patients with unexplained recurrent abortion (Ursa) and the level of interleukin-22 (IL-22).Methods: from September 2013 to February 2014, 15 patients with unexplained recurrent abortion were selected as study group, and those with normal early pregnancy as control group.The cubital venous blood was collected 5 ml before the abortion and the decidua tissue was retained after the abortion.The proportion of Th17 Th22 cells and the level of IL-22 in peripheral blood and decidua were detected by flow cytometry and Elisa.The percentage of Th17 cells in decidua was higher than that in peripheral blood, and the difference was statistically significant (P 0.05).The percentage of Th22 cells in decidua was higher than that in peripheral blood, and the difference was statistically significant (P 0.05).3. The levels of IL-22 in peripheral blood and decidua in URSA group were 181.98 卤8.10 PG / ml, 198.52 卤10.98 PG / ml, respectively, which were significantly higher than those in NP group (104.28 卤4.73 PG / ml, 110.47 卤6.43 PG / ml, P 0.01).The level of local IL-22 in decidua was higher than that in peripheral blood, and the difference was statistically significant (P 0.01).4,姣旇緝URSA缁勬偅鑰呬笌NP缁勬偅鑰呭鍛ㄨ鍙婅湑鑶滅粍缁囦腑IL-22缁嗚優鍥犲瓙姘村钩涓嶵h17缁嗚優姣斾緥鐨勭浉鍏虫
