摘要
Objective:To investigate the roles of COX-2,TNF-α,IL-6 in the pathogenesis of autoimmunetype recurrent spontaneous abortion(RSA).Methods:RT-PCR was used to detect the mRNA of COX-2,TNF-α.IL-6 in the trophoblast cells of murine RSA and normal pregnant models.The COX-2,TNF-α.IL-6 protein expressions were determined by using immunohistochemisry staining method.The COX-2,TNF-α,IL-6 protein expressions were determined by ELISA.Results:The embryo loss rates in experiment group was significantly higher than that in normal pregnancy control group,the expression of COX-2,TNF-α,IL-6 in the trophoblast cells of murine RSA and normal pregnant models.The expression of COX-2 in autoimmunetype recurrent spontaneous abortion was significantly lesser than in normal pregnant models.The expression of TNF-α,IL-6 in autoimmune-type recurrent spontaneous abortion was significantly higher than in normal pregnant models.There was a positively correlation between TNF-αand IL-6.There was no relationship between COX-2,TNF-αand IL-6.Conclusions:The abnormal expression of COX-2,TNF-αand IL-6 may result in RSA.
