ABSTRACT
Objective To determine whether therapy of Salvia miltiorrhiza,Ligustrazine and magnesium sulfate has effect on concentrations of SOD, MDA,NO,ET,TXA 2, PGI 2 in blood and outcomes of women with pregnancy-induced hypertension(PIH). Methods Two hundred and twenty-five women with moderate PIH were studied while treated with Salvia miltiorrhiza, Ligustrazine and magnesium sulfate in group A, B, and C(n=75 respectively). Concentrations of SOD, MDA, NO, ET, TXA 2, PGI 2 in blood, blood pressure, postpartum hemorrhage, fetal distress, and neonatal asphyxia were monitored. Results In maternal blood the concentrations of SOD in the three groups before and after treatment were 178.3?4.1 vs 219.5?4.1、190.4?2.4 vs 208.4? 2.4、176.1?3.4 vs 221.1?2.2、MDA 11.4?1.3 vs 7.2?1.2、13.0?2.7 vs 8.6?2.0、10.3?1.5 vs 7.1?1.1、NO 747?202 vs 940?232、798?159 vs 907?142、776?212 vs 862?189、ET 78.3?4.5 vs 62.3?3.8、78.3?4.3 vs 58.3?4.4、76.9?3.9 vs 60.2?2.9、TXA 2 560?28 vs 486?27、537?27 vs 502?20、558?25 vs 472?21、PGI 2 162?13 vs 217?14、167?17 vs 227?16、169?13 vs 213?11 respectively,there were significant differences between betore and after treatment (P0.05). Conclusions It is showed that Salvia miltiorrhiza ,Ligustrazine and magnesium sulfate can well balance circulating levels of SOD, MDA, NO, ET, TXA 2, and PGI 2 in women with PIH. Magnesium sulfate may interfere the results of the monitoring on the fetal heart rate.
ABSTRACT
Objective To study the blood pressure changing patterns in normal pregnancy and pregnancy induced hypertension(PIH). Methods 24 hour ambulatory blood pressure monitoring (ABPM) were performed in 38 cases of normal pregnancy and 36 cases of PIH during 18～20,28～30 and 38～40 gestational week. Results The 24 hour mean blood pressure were increased with pregnancy advanced. In normal pregnancy, a typical circadian rhythm of blood pressure pattern was shown that it increases during the day and decreased during the night with the disparity of (16.3? 4.1)%, (14.1?3.2)% and (15.7?2.0)% in three different gestational week respectively. In moderate and severe PIH, the 24 hour mean blood pressure,blood pressure load and the frequence of abnormal rhythm were significantly higher than those in mild PIH and normal pregnancy, while the disparity between day and night blood pressure was lower. Conclusion The blood pressure patterns show a typical circadian rhythm in most normal pregnancy. The more severe the PIH is, the higher rate of abnormal blood pressure rhythm occured.
