摘要
目的研究子宫内膜树突状细胞(DC)在不明原因复发性自然流产(uRSA)患者分泌期子宫内膜的表达情况。方法根据子宫内膜形态学Noyes标准,对在本中心就诊的uRSA患者(uRSA组,n=113)与男性因素不孕患者(对照组,n=35)进行子宫内膜分期;以CD1_a与CD83分别作为子宫内膜未成熟树突状细胞(iDC)与成熟树突状细胞(m DC)的表面标志物,并利用免疫组织化学技术检测患者分泌期子宫内膜CD1_a与CD83阳性细胞的数量,并通过Vectra~?自动病理成像定量分析系统分别计算其阳性细胞率。结果 uRSA组分泌期子宫内膜CD1_a阳性细胞率无明显变化,而CD83阳性细胞率[(2.03±1.60)%]显著高于对照组[(0.81±1.11)%,P=0.000];两组患者子宫内膜CD1_a阳性细胞率从分泌早期到中期均呈递减趋势,而CD83阳性细胞率从分泌早期到中期均呈递增趋势;与对照组相比,uRSA组子宫内膜CD1_a阳性细胞率在分泌早期和中期均无明显变化,而uRSA组子宫内膜CD83阳性细胞率在分泌早期[(1.64±1.20)%]和中期[(2.20±1.60)%]均显著高于对照组[(0.17±0.11)%,P=0.000;(0.63±0.78)%,P=0.000]。结论 uRSA组患者子宫内膜分泌早期和中期CD83阳性细胞率异常升高,提示其可能影响子宫内膜容受性,从而导致妊娠失败。
Objective To explore the uterine dendritic cell（uDC） levels in the secretory phase of patients with unexplained recurrent spontaneous abortion（uRSA）. Methods The expression of CD1 a and CD83 in the endometrium of women with uRSA（113 cases） and infertility women with male factors（35 cases） were detected by immunohistochemical staining technique. The percentages of CD1 a＋ and CD83＋ cells were measured by Vestra？ automatic pathological imaging quantitative analysis system. Results There was no significant difference in the proportion of CD1 a＋ cells in the secretory phase of patients with uRSA and control group. However, the percentage of CD83＋ cells in the secretory phase of patients with uRSA [（2.03±1.60）%] was significantly higher than that in control group [（0.81±1.11）%, P=0.000]. In addition, the percentages of CD83＋ cells during early-[（1.64±1.20）%] and mid-secretory phase [（2.20±1.60）%] from uRSA group were significantly higher than those in control group [（0.17±0.11）%, P=0.000;（0.63±0.78）%, P=0.000, respectively]. The percentage of CD1 a＋ cells was gradually decreased through the early-and mid-secretory phase in both groups, while the percentage of CD83＋ cells was gradually increased. Conclusion The abnormal elevation of uterine CD83＋ cells in early-and mid-secretory phase of patients with uRSA may affect the endometrial receptivity, which may lead to pregnancy failure.
