Caspase-8和SAA在稽留流产孕妇绒毛组织中的表达及意义
Expression and significance of Caspase-8 and SAA in villi of pregnant women with missed abortion
目的 探讨天冬氨酸特异性半胱氨酸蛋白酶-8(cysteinyl aspartate-specific proteinase-8,Caspase-8)和血清淀粉样蛋白A(serum amyloid A,SAA)在稽留流产与正常早孕患者绒毛组织中的表达差异。 方法 通过免疫组化法(immuno- histochemistry, IHC)检测33例对照组(正常早孕要求终止妇女)及54例试验组(稽留流产患者)绒毛组织中Caspase-8和SAA的表达情况,并比较其表达差异。 结果 Caspase-8和SAA在绒毛及蜕膜组织中均有表达,稽留流产组Caspase-8(χ2 =19.837,P<0.001)和SAA (χ2 =12.249,P<0.001)的表达明显高于对照组,且两者的表达差异均有统计学意义。 结论 稽留流产患者绒毛组织中Caspase-8和SAA的高表达,提示其可能参与稽留流产的发生。
Objective To investigate the differences in the expression of cysteinyl aspartate-specific proteinase-8 (Caspase-8) and serum amyloid A (SAA) in the villi of patients with induced abortion and normal early pregnancy. Methods The expression of Caspase-8 and SAA in the chorionic tissue of 33 women with normal early pregnancies requiring termination and 54 patients with induced abortion was detected by immuno-histochemistry (IHC), and the positive expression was calculated. Results Caspase-8 and SAA were expressed in both villi and decidua.The expression of Caspase-8 (χ2 =19.837, P<0.001) and SAA (χ2 =12.249, P<0.001) in the group with induced abortion was significantly higher than that in the control group, and the difference in the expression of both was statistically significant. Conclusion The high expression of Caspase-8 and SAA in the chorionic tissue of patients with induced abortion suggests that it may be one of the possible reasons for the occurrence of induced abortion.
