Regulation of magnesium sulfate combined with nifedipine and labetalol on disease-related molecules in serum and placenta in the treatment of preeclampsia.

Abstract

To explore the regulatory effect of magnesium sulfate combined with nifedipine and labetalol on disease-related molecules in serum and placenta in the treatment of preeclampsia. Altogether 100 patients with preeclampsia admitted to the Children & Women's Healthcare of Laiwu City were selected. They were divided into control group and experimental group according to different treatment methods. Among them, 51 patients in the control group were treated with magnesium sulfate combined with nifedipine, and 49 patients in the experimental group were treated with labetalol on the basis of the treatment in the control group. The therapeutic effects of the two methods were compared. The levels of the following factors in the two groups were compared: kallikrein expression, pregnancy-associated plasma protein A (PAPP-A), pregnancy-specific β1 glycoprotein (SPI), placental growth factor (PLGF), human placental prolactin (HPL), transforming growth factor β1(TGF-β1), vascular cell adhesion molecule 1 (VCAM-1) and E-selectin in serum and placenta tissues. After treatment, the blood pressure in the experimental group was lower than that in the control group (p<0.05). The expression of kallikrein in serum and placental tissue of the patients in the experimental group was higher than that of the patients in the control group (p<0.05); PAPP-A level was lower than that in the control group (p<0.05); TGF-β1 level was higher than that in the control group (p<0.05); VCAM-1 and E-selectin were lower than those in the control group (p<0.05), and kallikrein and TGF-β1 in serum and placenta in the non-occurrence group were higher than those in the occurrence group (p<0.05). The serum and placenta PAPP-A, VCAM-1, and E-selectin in the non-occurrence group were lower than those in the occurrence group (p<0.05). Magnesium sulfate combined with nifedipine and labetalol has good efficacy in the treatment of preeclampsia. They can promote the expression of endogenous kallikrein, reduce the level of pregnancy-related hypertension predictors, and weaken the infiltration ability of cytotrophoblasts.
