B 族维生素干预后血清同型半胱氨酸水平对早期反复流产患者保胎效果的影响

目的：探讨B族维生素干预后血清同型半胱氨酸水平对早期反复流产患者保胎效果的影响。方法排除导致自然流产其它因素，选择血清同型半胱氨酸水平在10μmol／L及以上的患者80例，随机分为两组，治疗组40例孕前给予B族维生素治疗1月后复查血清同型半胱氨酸水平并继续服用上述药物至妊娠12周；对照组40例孕前后均不予上述药物治疗。孕后两组均常规保胎观察至妊娠12周，行B超检查证实活胎并胎儿发育正常者为保胎成功。结果治疗组服用B族维生素1月后血清同型半胱氨酸水平平均下降44％，妊娠36例，保胎成功30例，保胎成功率83％；对照组妊娠32例，保胎成功18例，保胎成功率56％。结论对于早期反复流产患者，B族维生素可有效降低血清同型半胱氨酸水平，并可有效提高保胎成功率。

The effect of plasma homocystein levels after vitamin B intervention on patients with early recurrent spontaneous abortion

Objective To investigate the effect of plasma homocystein levels after vitamin B intervention on patients with ear‐ly recurrent spontaneous abortion .Methods 80 patients of Plasma homocystein level ≥10μmol/L with early recurrent sponta‐neous abortion excluding other factors were selected .They were divided into a treatment group （n=40） which took Plasma ho‐mocystein level after taking vitamin B one month before prognancy then continued to take them till 12 th week of pregnancy and a control group（n=40） which took no medicine before and after pregnancy .Two groups were routine tocolysis for up to 12 weeks after pregnancy .The normal fetal development was considered successful tocolysis after B‐ultrasonography examination . Results Homocystein levels in treatment group dropped by an average of 44% after taking vitamin B one month .Tocolysis suc‐cessful rate was 83% in 36 cases of pregnancy ,which was different from that in 32 cases of pregnancy of the control group （56% ） .Conclusion Vitamin B could reduce homocystein levels of patients with early recurrent spontaneous abortion and effec‐tively improve the rate of tocolysis successful .
