查询词典 gestational

In this experiment, the object was ovaries from adult mouse, we use western blot technique and immuno-histochemistry method to study and research expression and distribution changes of ERβand p-ERβduring oestrous cycle and early gestational period (1~11d).

本实验以成年雌鼠卵巢为实验材料，分别采用western blot技术和免疫组织化学方法，研究ERβ和p-ERβ在小鼠卵巢各发情周期和妊娠早期(1~11d)表达量与定位分布的变化规律。

Therefore it is necessary to research the expression and distribution of ERβan p-ERβwith the experimental model of the mouse ovaries during oestrous cycle and early gestational period, discuss the relationship between the two active conditions of the molecule and function performing in ovary.

因此以正常小鼠发情周期及妊娠期卵巢为实验模型，进行ERβ和p-ERβ在其中的定位表达研究，并探讨该分子两种活性状态与卵巢功能执行的关系是必要的。

This article studied differences in postpartum fatigue and birth outcomes between women who pushed immediately and those who delayed pushing during the second stage of labor. Data were collected from primiparous women in their 38th to 42nd gestational week who did not receive epidural analgesia during labor and were free of complications during pregnancy. Using a quasi-experimental design, 72 participants selected by convenient sampling were assigned based on individual participant's preference to either an experimental or control group. For the experimental group, pushing was delayed until the point after full cervical dilation at which the mother felt a strong physical pushing reflex, the fetal head had both descended to at least the +1 level in the pelvis and turned to the occiput anterior position, and uterine contractions were at least 30 mmHg. For the control group, the physician instructed mothers to begin pushing after full cervical dilation at the point when the fetal head was in the occiput anterior position and uterine contractions were at least 30 mmHg.

本研究目的在探讨初产妇女第二产程立即用力与延迟用力对产后疲惫及生产结果的影响，收案对象为怀孕38-42周初产妇女、待产期间未施打硬脊膜外麻醉，且怀孕期间无任何合并症，於待产期间向其解释研究目的及收案方法后予以收案，采类实验设计法，以方便取样并依个案之意愿分派於实验组及控制组，实验组於子宫颈完全扩张后等到强烈想用力的感觉、胎头位到达坐骨棘连线下1公分以下、胎头位置转到枕前位、子宫收缩规律强度至少30mmHg才教导向下用力；控制组於子宫颈完全扩张后即教导向下用力，共收案72位。

Except 58 cases missed and 5 cases induced abortion, we followed up 163 cases(241 kidneys) in different gestational age and postnatal period. Among them, 209 kidneys (86.72%) were discovered pyelectasis between 5mm to l0mm. The pyelectasis of 30 kidneys(12.45%) was between l0mm to l5mm, and that of 2 kidneys(0.83%) was thicker than 15mm. Follow-up result is as follow: 137 cases(214 kidneys) were recovered in normal in fetus period or postnatal 15 months. Their pyelectasis was thinner than 5mm(88.80%). Among them, 16 cases(2l kidneys) were recovered in fetus period(8.71%). 121 cases(193 kidneys) were recovered in postnatal 15 months(80.09%). The rest 20 kidneys' pyelectasis was between 5mm to l0mm(8.30%). 4 kidneys' pyelectatis was between 10mm to l5mm(1.66%), and 3 kidneys' pyelectasis was thicker than l5mm(1.24%).
