摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗观察环孢素A对内毒素诱导的子痫前期大鼠的改善作用,并通过检测环孢素A对子痫前期大鼠免疫功能、胎盘氧化应激反应及一氧化氮的影响,探讨其作用机制。
〖HTH〗方法〖HTSS〗〖KG*2〗妊娠大鼠(30只)随机分为对照组、模型组及治疗组(每组10只),模型组和对照组大鼠以低剂量内毒素建立子痫前期模型。治疗组大鼠分别予孕15、16、17、18 d经腹腔注射环孢素A注射液。分别于孕14、19 d测定各组大鼠血压和24 h蛋白尿。孕20 d处死大鼠,采用酶联免疫吸附测定法检测各组大鼠血浆白细胞介素6(interleukin6,IL6)、肿瘤坏死因子α(tumor necrosis factor α,TNFα)、TNFγ含量,采用流式细胞术检测外周血CD4+CD25+FoxP3+Treg细胞/CD4+细胞亚群比值,分别采用硫代巴比妥酸法、光泽精法和硝酸还原酶法测定胎盘组织的活性氧活性、丙二醛和一氧化氮含量。
〖HTH〗结果〖HTSS〗〖KG*2〗孕19 d结果显示,与模型组比较,治疗组收缩压和24 h蛋白尿均明显降低(P<005)。孕20 d结果显示, 与模型组比较,治疗组胎盘质量、胎鼠质量、外周血CD4+CD25+FoxP3+Treg细胞/CD4+细胞亚群比值和一氧化氮含量明显升高,而外周血IL6、TNFα、TNFγ含量和胎盘组织活性氧活性、丙二醛含量则明显下降,差异均有统计学意义(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗环孢素A能改善内毒素诱导的子痫前期大鼠的围产结局,其作用机制可能与环孢素A能抑制子痫前期大鼠的免疫反应和胎盘氧化应激反应、提高胎盘一氧化氮含量有关。

Abstract: [Abstract] Objective〖HTSS〗〓To observe the effect of cyclosporine A on rats with preeclampsia(PE), and to explore its mechanism by determining the influence of cyclosporine A on the immune status, placenta oxidant stress and nitric oxide(NO) in rats with preeclampsia.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 30 rats were randomly divided into 3 groups(10 in each group): the control group, the PE group and the treatment group. The rats in the PE group and the treatment group received lowdose endotoxin to establish the PE models. The rats in the treatment group received intraperitoneal injection of cyclosporine A on the 15 th, 16 th, 17 th, 18 th gestation days. Blood pressure and 24 hour urine protein were determined on the 14 th and the 19 th gestation days, respectively. Rats were all sacrificed on the 20 th gestation day. Serum levels of IL6, TNFα and TNFγ were determined by ELISA and the ratio of blood CD4+CD25+FoxP3+Treg cells to CD4+ cells were tested with flowcytometry. Activity of reactive oxygen species (ROS), malondialdehyde (MDA) and NO levels in the placenta tissue were respectively determined.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓On the 19 th gestation day, the blood pressure and 24 hour urine protein in the treatment were both significantly decreased compared with the PE group(P<001). On the 20 th gestation day, when compared to the PE group, the placenta weight, weight of the fetal rat and the ratio of blood CD4+CD25+FoxP3+Treg cells to CD4+ cells were all significantly decreased, while the serum levels of IL6, TNFα and TNFγ, as well as the activity of ROS and the MDA level in the placenta tissue were significantly increased in the treatment group(P<001).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Cyclosporine A can improve the perinatal outcome in rats with PE induced by endotoxin. The possible mechanism may lay in the inhibition of immune reaction and placenta oxidant stress, and the increasing level of NO by cyclosporine A.
