Effect of folic acid and vitamin supplement on endothelial injury and placental blood perfusion in patients with hypertensive disorder complicating pregnancy

摘要

Objective: To study the effect of folic acid and vitamin supplement on endothelial injury and placental blood perfusion in patients with hypertensive disorder complicating pregnancy. Methods: A total of 62 patients who were diagnosed with preeclampsia in Wuhan Red Cross hospital between March 2015 and February 2017 were selected as the research subjects and randomly divided into two groups, the observation group received folic acid, vitamin and conventional symptomatic treatment, and control group accepted conventional symptomatic treatment. Serum contents of endothelial injury markers and oxidative stress indexes were detected before treatment and 2 weeks after treatment; the expression of apoptosis genes in the placenta were detected after delivery. Results: 2 weeks after treatment, serum ET-1, tTG, sFlt-1, sEng, MPO, IMA, MDA and AOPP levels of both groups of patients were significantly lower than those before treatment, and serum ET-1, tTG, sFlt-1, sEng, MPO, IMA, MDA and AOPP levels of observation group were significantly lower than those of control group; after delivery, Fas, Bax and Caspase-3 mRNA expression levels in placenta tissue of observation group were significantly lower than those of control group while Bcl-2, Survivin and Livin mRNA expression levels were significantly higher than those of control group. Conclusion:Folic acid and vitamin supplement can significantly improve the endothelial injury and placental blood perfusion in patients with hypertensive disorder complicating pregnancy.
