1. Objective To study the changes of the fetal circulation in intrauterine growth retardation (IUGR) cases.

2. The fetal circulation was examined in relation to estimated fetal weight.

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

4. Fetal growth characteristics and fetal circulation variables were assessed with ultrasound and Doppler examinations in 1215 healthy women.

5. These multi-color contain lead, mercury, heavy metals and so on, mothers applied, may enter the fetal circulation through the body and affect fetal development.

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

7. Some of high risk factors, such as hereditary and acquired thrombophilia, maternal and fetal circulation abnormality, play an important role in the pathogenesis of placental thrombosis.

8. Recent researches demonstrated that hypoxemia is a specific trigger for elevation of activin-A in fetal circulation and is a main regulatory mechanism for it.

9. 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.

10. Recent researches demonstrated that hypoxemia is a specific trigger for elevation of activin -A in fetal circulation and is a main regulatory mechanism for it. The high correlation of act...
