Objective:To test the hypothesis that peripheral blood mononuclear cells (PBMCs) in women with unexplained recurrent abortion (URA) produce T-helper 1 (Th1)-type cytokines in response to trophoblast antigens. Methods:...Objective:To test the hypothesis that peripheral blood mononuclear cells (PBMCs) in women with unexplained recurrent abortion (URA) produce T-helper 1 (Th1)-type cytokines in response to trophoblast antigens. Methods: A total of 25 women with URA and 15 reproductively normal parous control women participated the study. Supernatants from trophoblast-activatied PBMCs from all participants were tested by enzyme-linked immunosorbent assay(ELISA) for Th1-type cytokines [interleukin-2 (IL-2), interferon gamma (IFN-γ)] and Th2-type cytokines (IL-4,IL-10). Results: The levels of IL-2, IFN-γ in trophoblast-activitated PBMCs supernatants from URA patients were highr than those from reproductively normal women (P<0.05). In contrast, the supernatants from URA patients contained lower Th2-type cytokines (IL-4,IL- 10) (P<0.05). Conclusions: Whereas Th1-type immunity to trophoblast is assoicated with URA and may play a role in reproductive failure, Th2-type immunity may a natural response to trophoblast contributing to successful pregnancy.展开更多

The purpose of the present study is to assess the clinical values of integrated traditional and western medicine in treating the immune abnormality type of RSA.Methods: The aborters were treated by Zhibai Dihuang Pills for anti-zona pellucida antibodies, and clearing evil Heat, removing Dampness, replenishing blood and activating circulation by Chinese medicinal herbs recipe for anti-phospholipid and anti-ABO group antibodies.Results: After they had been treated by these recipes, 92.3% became pregnant with normal delivery. It was found in dynamic investigation that level of the antibodies turned to decrease gradually during the treatment, and that of anti-phospholipid and anti-ABO group antibodies increased again at beginning of pregnancy and then decreased gradually with continuing the treatment.Conclusion: Chinese herbs recipe could be used to treat RSA of immune abnormality-type by way of decreasing the elevated levels of auto and/or allo-antibodies.展开更多
