In our population, increased nuchal translucency thickness is the most important ultrasonographic marker of trisomy 21. In contrast, the nasal bone seems to have a less prominent role in identifying the fetus at risk for trisomy 21 due to its lower detection rate.

在我国人口中，透明膜厚度的增加是21三体综合症最重要的超声波标指标，相比之下，鼻骨似乎在诊断胎儿患21三体综合症风险上没有那么重要，这主要是其低的检出率。

Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.

采用单纯硬膜外腔阻滞、蛛网膜下腔-硬膜外腔联合给予低浓度麻醉药及镇痛药、单纯蛛网膜下腔给予低浓度镇痛药(C组芬太尼25μg，D组芬太尼20μg)等四种不同的方法对130例初产妇进行分娩镇痛，比较几组的镇痛效果、不良反应及对产程、分娩方式、产后出血、胎儿及新生儿等的影响，并与40例正常未干预组产妇比较。

So B-on is the impact of the fetus, so do not do too much the number, the time interval is too short not to.

Most techniques,however are time consuming,labor intensive,and require considerable onside expertise.

最近发现在孕妇的血浆中存在胎儿DNA，这一发现为非损伤性产前基因诊断开辟了新途径。
