子痫前期患者血清Treg细胞含量及超氧化物歧化酶水平变化的临床意义

目的研究子痫前期患者血清Treg细胞含量、超氧化物歧化酶(SOD)水平与患者病情及临床预后的关系。方法选择2015年9月至2016年9月期间在该院治疗的子痫前期患者40例作为研究对象,根据患者病情分为轻度子痫前期患者25例(轻度子痫前期组)、重度子痫前期患者15例(重度子痫前期组),并以20例健康妊娠妇女作为对照组,对比各组患者外周血Treg细胞、血清SOD水平,并探讨Treg细胞含量、血清SOD水平与子痫前期患者病情及其预后的关系。结果重度子痫前期组收缩压、舒张压分别为(145.3±10.6)、(102.3±7.8)mm Hg,早产、胎盘早剥、胎儿窘迫发生率分别为33.3%、20.0%、13.3%,孕前体质量指数为(25.4±1.3)kg/m~2,明显高于轻度子痫前期组和对照组,而轻度子痫前期组高于对照组。重度子痫前期组Treg细胞含量、SOD水平分别为(2.3±0.7)×10~6/L、(2.6±0.7)μg/mL,明显低于轻度子痫前期组和对照组,而轻度子痫前期组为(3.4±0.6)×106/L、(4.3±0.9)μg/mL,明显低于对照组,差异具有统计学意义(P0.05)。Logistic回归分析结果提示体质量指数(P=0.018)、Treg细胞含量(P=0.024)、SOD水平(P=0.029)是妊娠结局不良的独立风险因素。结论子痫前期患者外周Treg细胞含量、血清SOD水平与妊娠结局不良密切相关。

Clinical significance of the changes of serum Treg cells content and superoxide dismutase levels in patients with preeclampsia

Objective To study the relationship between serum Treg cells content and superoxide dismutase(SOD) level with the severity and clinical prognosis in the patients with preeclampsia.Methods Forty cases of preeclampsia in our hospital from September 2015 to September 2016 were selected as the research subjects divided into the mild preeclampsia group(25 cases) and severe preeclampsia groups(15 cases) according to the disease severity,and 20 healthy pregnant women served as the control group.The peripheral blood Treg cells and serum SOD level were compared between the two groups.The relationship between Treg cell content and serum SOD level with the disease severity and prognosis in the patients with preeclampsia was investigated.Results The systolic and diastolic blood pressure in the severe preeclampsia group were(145.3±10.6)mm Hg and(102.3±7.8)mm Hg,the occurrence rates of premature delivery,placental abruption and fetal distress were 33.3%,20.0% and 13.3% respectively,BMI before pregnancy was 25.4±1.3,which were significantly higher than those in the mild preeclampsia group and control group,while the mild preeclampsia group was higher than the control group.The Treg cell content and SOD level in the severe preeclampsia group were (2.3±0.7)×106/L and(2.6±0.7)μg/mL,which were significantly lower than those in the mild preeclampsia group and control group and which in the mild preeclampsia group were (3.4±0.6)×106/L and(4.3±0.9)μg/mL,and significantly lower than those in the control group,the differences were statistically significant(P<0.05).The Logistic regression analysis results indicated that BMI index(P=0.018),Treg cell content(P=0.024) and SOD level(P=0.029) were the independent risk factors for poor pregnancy outcome.Conclusion The peripheral blood Treg cells content and serum SOD level are closely related to poor pregnancy outcome in the patients with preeclampsia.
