雌四醇(E_4)对子宫血管有扩张作用,与胎儿的肝脏功能有密切关系.检测孕妇尿中E_4的含量,可以监测、评价胎儿宫内生长发育状况。本文通过48例68个尿样检查发现E_4最早出现的时间为29~(+5)孕周.2例经动态观察,1例含量随孕周增长而增加,1例在38~(+4)周因发生妊高征,E_4由阳转阴.48例中分别在18例正常妊娠,1例轻度、2例中度妊高征和1例孕39~(+2)周合并贫血孕妇中检测到E_4而在10例妊高征中7例未测到E_4.说明E_4含量受妊高征等因素的影响,其间的关系值得进一步探讨。
Estriol (E_4) on the expansion of uterine blood vessels, and fetal liver function are closely related to the detection of urinary E_4 content of pregnant women, you can monitor and evaluate the intrauterine growth and development status. In this paper, the 48 cases of 68 urine samples found E_4 earliest time for 29 ~ (+5) gestational weeks .2 cases of dynamic observation, 1 case of content increased with gestational age increased, 1 case of 38 ~ (+4) Week due to pregnancy-induced hypertension, E4 by the yin and yang .48 cases were 18 cases of normal pregnancy, 1 case of mild, 2 cases of moderate pregnancy-induced hypertension and 1 case of pregnant 39 ~ (+2) weeks of pregnant women with anemia E_4 detected in 10 cases of pregnancy-induced hypertension in 7 cases did not find E_4. E_4 content by factors such as pregnancy-induced hypertension, the relationship worthy of further study.
