目的:观察A、C型子宫内膜种植窗期形态学的特征。方法:选择自然周期尿LH峰日A、C型子宫内膜各10例。应用组织形态学方法和图像分析以及扫描电镜技术观察、分析组织形态变化及胞饮突特征。结果:①组织形态特征:C型子宫内膜的腺腔轻度增大,见核下空泡,A型子宫内膜的腺腔增大明显,腺腔内分泌旺盛;图像分析两组子宫内膜组织结构定量分析指标比较差异有显著性(P<0.05)。②扫描电镜:在120倍镜下观察,C型子宫内膜表面皱缩,较A型子宫内膜发育差;在2500倍镜下时,C型子宫内膜胞饮突发育滞后于A型子宫内膜。结论:晚卵泡期C型子宫内膜种植窗期内膜腺体发育和胞饮突发育均滞后于A型子宫内膜。
OBJECTIVE: To observe the morphological characteristics of the window of implantation of type A and C endometrium. Methods: Choose the natural cycle urine LH peak A, C-type endometrium in 10 cases. Histopathology, image analysis and scanning electron microscopy were used to observe the changes of histomorphology and the characteristics of pinopodes. Results: ① The morphological features of the endometrium of C type were mildly enlarged, the vacuoles of the nucleus under the nucleus, the glandular cavity of A type endometrium increased obviously, Quantitative analysis of organizational structure indicators were significantly different (P <0.05). ② Scanning electron microscopy: C-type endometrial surface shrinkage, compared with type A endometrial dysplasia observed at 120 times microscope; C-type endometrial cell protrusion development lagged at type A Endometrium. CONCLUSION: Endometrial gland development and cell development in late-follicular C-type endometrium lag behind type A endometrium.
