Conclusions : the study suggests that the proliferation and adhesion of trophoblast in placenta of patients with early abortion was declined 结论：研究提示早期自然流产患者胎盘中滋养细胞增殖、粘附能力下降。

Objective : to study the expression of proliferating cell nuclear antigen ( pcna ) and fibronectin ( fn ) in placenta of early abortion 摘要目的：观察增殖细胞核抗原、纤粘连蛋白在早期自然流产患者胎盘中的表达情况。
3.
Results : the expression of pcna and fibronectin in placenta of 30 patients with early abortion was significantly reduced ( p < 0 . 05 ) 结果：早期自然流产患者较正常早期妊娠胎盘中增殖细胞核抗原、纤粘连蛋白的表达减弱( p < 0 . 05 ) 。
