目的 探究子宫内膜息肉(EP)中γδT细胞和相关炎症因子的表达及其临床意义。方法 研究对象为因EP不孕的患者(EP组,n=57)和非子宫因素的不孕症患者(Con-trol 组,n=44)。分别取EP组织和正常子宫内膜组织。使用独立样本t检验或Wilcoxon秩和检验评价两组一般特征,使用免疫荧光法观察增殖期子宫内膜和子宫内膜息肉中CD3和TCRγδ阳性细胞的表达,使用ELISA检测组织匀浆中白细胞介素(IL)-17和干扰素(IFN)-γ的表达水平,使用简单线性回归分析EP中γδT细胞的表达情况与相关各炎症细胞因子的相关性。结果 EP组织中γδT细胞数目明显增加,炎性因子IL-17和IFN-γ水平也明显升高,并呈线性关系(P<0。05)。结论 γδT细胞数目与EP导致的不孕症有关,提示可能通过调控细胞亚群失衡影响炎症因子的表达导致了胚胎植入失败。
Investigation the association between γδT cells with endometrial polyps
Objective To investigate the expression and clinical value of γδT cells and related inflammatory factors in endometrial polyps(EP).Methods Subjects were patients with infertility due to EP(EP group,n=57)and infertility due to non-uterine factors(Control group,n=44).EP tissues and normal endometrial tissues were taken,respectively.The general characteristics of the two groups were evaluated by independent samples T-test or Wilcoxon rank sum test.The expressions of CD3 and TCRγδ in proliferative endometrium and endometrial polyps were observed by immunofluorescence,and the expressions of IL-17 and IFN-γ in tissue homogenate were detected by ELISA.Uni-variable linear regression was used to analyze the correlation between the number of γδT cells and the expression level of IL-17 and IFN-γ.Results Both the number of γδT cells and he levels of IL-17 and IFN-γsignificantly increased in endometrial polyp tissues,and the relationship between is linear(all P<0.05).Conclu-sion γδT cells are associated with EP among infertile women,which may lead to embryo implantation failure by affecting the expression of inflammatory factors and regulating the imbalance of cell subsets.
