To explore the effect of nourishing yin and calming liver method on blood lipid level and pregnancy outcome of preeclampsia (PE) pregnant women. Methods:A total of 140 PE pregnant women in our hospital from January 2014 to December 2017 were randomly divided into observation group and control group, with 70 cases in each group.

The traditional Chinese medicine (TCM) syndrome score, blood lipid levels and related indexes before and after treatment in 2 groups were compared; clinical effect and pregnancy outcome of 2 groups of pregnant women were counted. Results:Compared with before treatment, the TCM syndrome scores such as headache, vertigo, abdominal pain of 2 groups after treatment significantly decreased, and observation group was significantly lower than control group (P<0.01); Compared with before treatment, the levels of TC, TG, LDL, MAP and 24 h UAE of 2 groups after treatment decreased significantly (P<0.01), and observation group was significantly lower than control group (P<0.05 or P<0.01); The serum HDL level of 2 groups increased significantly, and observation group was higher than control group (P<0.01); The total effective rate of observation group after treatment was significantly higher than that of control group (85.17% vs 68.57, P<0.05); The number of unplanned pregnancy termination of observation group was significantly less than control group, and the number of terminations in the plan was larger than control group (P<0.05); The average duration of gestational weeks before termination of pregnancy of observation group was significantly longer than the control group (P<0.01); There was no significant difference in postpartum hemorrhage and neonatal weight between 2 groups (P>0.05).
