陈凤林发现免疫性流产的机理Chenfenglin discovered the mechanism of immune miscarriage

陈凤林教授对免疫性习惯性流产的认识：

Professor Chenfenglin's understanding of immunohabitual miscarriage:

他指出免疫性流产的起因是由于经期性生活、人流或分娩时，夫源组织通过开放的子宫内膜静脉进入母体，母体产生了特异性抗胚胎抗体。

He pointed out that the cause of immune miscarriage is due to the fact that during menstrual sex, miscarriage, or childbirth, the husband's tissue enters the mother through an open endometrial vein, and the mother produces specific anti-embryo antibodies.

再次妊娠时，抗胚胎抗体与胎盘表层的Fibronectin 网发生体液免疫反应，Fibronectin遭到破坏后，胎儿绒毛组织暴露于母血中，细胞免疫发生，胚胎停育，继而发生自然流产。

During the second pregnancy, an humoral immune response occurs between the anti-embryo antibody and the Fibonectin net on the surface of the placenta. After Fibonectin is destroyed, the fetal Villi tissue is exposed to the mother's blood, cell immunity occurs, the embryo stops breeding, and then spontaneous miscarriage occurs.

往往免疫性因素导致的停育时间基本在同一孕周内。

Often the duration of the interruption due to immunological factors is basically within the same gestation week.
