摘要 目的:探讨Th1/Th2细胞因子与NO在妊高征患者血清和胎盘组织中含量变化,分析其在妊高征发病中的作用及相互关系。方法:应用镀铜镉还原法和酶联免疫吸附双抗体夹心法,分别对41例妊高征患者、30例正常妊娠妇女血清和胎盘提取物NO和细胞因子IFN-γ、IL-2、IL-4、IL-10的水平进行检测。结果:与对照组相比,妊高征组血清和胎盘组织中IL-2、IFN-γ及IFN-γ/IL-4比值均明显升高(P<0.01或P<0.05),妊高征组血清中IL-10呈显著下降而IL-4显著升高(P<0.01);妊高征组患者血清和胎盘提取液中NO含量均明显低于正常妊娠组(P<0.01);妊高征组患者血清和胎盘提取液中NO含量与IFN-γ、IFN-γ/IL-4水平均呈负相关(血清中rIFN-γ=-0.642,P<0.01,rIFN-γ/IL-4=-0.258,P<0.05;胎盘中rIFN-γ=-0.765,P<0.01,rIFN-γ/IL-4=-0.331,P<0.05),妊高征组血清NO含量与IL-10呈正相关(rIL-10=0.202,P<0.05)。结论:妊高征发生与NO含量降低和Th1、Th2细胞因子水平改变密切相关;妊高征病理过程存在Th1/Th2平衡偏移,NO参与了这种偏移的调控。
