1·Objective To investigate the changes of hepatocyte growth factor(HGF)in maternal and fetal circulation of patients with preeclampsia.

目的探讨子痫前期母胎循环肝细胞生长因子（HGF）对子痫前期发病的影响。

2·Fetal echocardiography is based on the fetal circulation and segmental analysis, combined with clinical knowledge and dynamic image for diagnosis.

胎儿超声心动图是以胎儿心脏血流动力学为基础，节段诊断法为根本，结合临床知识及动态图像进行诊断。

3·The activation of neutrophil in mother of preeclampsia is related to the activation of neutrophil in fetal circulation. Neutrophil could play a role in fetal morbidity.

结论：子前期胎儿中性粒细胞的激活与母体中性粒细胞的激活相关，胎儿循环中存在中性粒细胞的激活，推测中性粒细胞在子前期胎儿病率中有一定作用。

4·With the growth of fetal and maternal blood circulation to increase.

随着胎儿的成长，母体的血液循环加重。

5·Rapid assessment of the maternal airway, breathing, and circulation and ensuring an adequate airway avoids maternal and fetal hypoxia.

快速地确定母体气道、呼吸及循环的情况并且确保足够的气道供气能避免母体和胎儿缺氧。

6·Conclusion This study offers a theoretic basis to the early prediction of fetal hyperdynamic circulation with Doppler ultrasound.

结论本研究为多普勒超声早期预测胎儿高动力循环状态提供了理论依据。

7·The relation between the changes and the fetal-placental circulation, as well as the pathog…

从这些变化与胎儿-胎盘循环的关系和对妊高征发病机理的意义进行了讨论。
