摘要
目的 探讨可溶性FMS样酪氨酸激酶-1(sFlt-1)及胎盘生长因子(PlGF)在子痫前期患者胎盘中的表达及相关性.方法 选择2021年8月—2022年12月住院分娩的诊断为子痫前期孕妇(研究组,10例)及正常孕妇(对照组,12例)作为研究对象,收集其临床资料及分娩时的胎盘组织,应用蛋白质印迹法(WB)检测胎盘组织中sFlt-1及PlGF的表达.结果 与对照组相比,研究组孕妇的年龄和体重指数无统计学差异(均P>0.05);对照组尿蛋白均为阴性,研究组尿蛋白均为阳性;研究组孕周和新生儿体重显著低于对照组(均P<0.01);收缩压和舒张压显著高于对照组(均P<0.01).WB检测发现,与对照组比较,研究组胎盘组织中的sFlt-1表达水平显著高于对照组,差异有统计学意义(Z=-3.962,P<0.01);PlGF在研究组中的表达显著低于对照组,差异有统计学意义(Z=-3.957,P<0.01).结论 胎盘组织中抗血管因子sFlt-1表达的升高、促血管形成因子PlGF的下降异常可调节血管舒缩,参与子痫前期的发生、发展及靶器官受损.
Abstract
Objective To investigate the expression and correlation of soluble FMS-like tyrosine kinase-1(sFlt-1)and placental growth factor(PlGF)in placenta of patients with preeclampsia.Methods The maternal placenta during delivery and clinical data of 10 patients with preeclampsia(study group)and 12 normal pregnant women(control group)were collected and retrieved,who gave birth in our hospital from August 2021 to December 2022.The expression of sFlt-1 and PlGF in placental tissue was detected by Western blotting(WB).Results Compared with the control group,there was no significant difference in the age and body mass index of pregnant women in the study group(P>0.05).Urine protein was negative in the control group and positive in the study group.The gestational age and neonatal weight in the study group were significantly lower than those in the control group(P<0.01).Systolic blood pressure and diastolic blood pressure in the study group were significantly higher than those in the control group(P<0.01).WB detection showed that compared with the control group,the expression level of sFlt-1 in placental tissue of the study group was significantly higher than that of the control group(Z=-3.962,P<0.01).The expression level of PlGF in the study group was significantly lower than that in the control group(Z=-3.957,P<0.01).Conclusion The increase of anti-vascular factor sFlt-1 expression and the decrease of pro-angiogenic factor PlGF in placental tissue of preeclampsia patients abnormally regulate vasomotor contraction and relaxation and participate in the occurrence,development,and target organ damage of preeclampsia.
