The pregnant women in the two groups were performed with sequential color Doppler ultrasound at gestation 30-40 weeks. The two-dimensional ultrasound apparatus was used to detect the uterine artery and umbilical artery. PI, RI, and S/D were recorded. The fetal BPD, head girth, femur length, and abdominal girth were measured. ELISA was used to detect 8-iso-PGF2α. The immunoturbidimetry was used to detect Cys-C and CRP.Results:The uterine artery PI, RI, and S/D in the observation group were significantly higher than those in the control group. The umbilical artery PI, RI, and S/D in the observation group were significantly higher than those in the control group. The fetal BPD, head girth, femur length, and abdominal girth in the observation group were significantly less than those in the control group. 8-iso-PGF2α, Cys C, and CRP levels in the observation group were significantly higher than those in the control group.Conclusions:The uterine artery and umbilical artery blood flow resistance in patients with HDP are significantly elevated, which can severely affect the placental blood perfusion and fetal growth and development, while the color Doppler ultrasound can provide a non-invasive diagnosis for fetal distress in uterus.展开更多
