RESUMO
Objective The evaluate action of serum L-arginine levels for predicting development of pregnant women with PIH,and analyze its effectiveness as clinical predictor.Methods Collecting 186 patients was performed a retrospective study.The PIH pregnant women was the experiment group,and the health pregnant women was the control group.In order to analyse the effect,the levels of L-arginine were measured in the early,middle and late period of pregnant women.Compared with the serum L-arginine in different groups with x2-test and t-test based on data type.Results Experimental group and control group subjects in age (x2 =2.426,P=0.119;t=1.218,P=0.229) and smoking before pregnancy (x2 =2.088,P=2.088),there was no significant differences,but the two groups of patients with BMI (x2 =8.772,P=0.003) and parity (x2 =6.083,P=0.014) was statistically.In different stages of pregnancy,the concentration of serum L-arginine had no statistical differences,and in the concentration of umbilical cord blood,serum L-arginine also had no statistical difference.There was a statistical differences in the serum L-arginine concentration of the cord blood for different number of pregnancies,but the concentrations of L-arginine in cord blood and in serum L-arginine.There were no significant difference in age,BMI and smoking pregnant.According to ROC curve analysis,for the diagnostic of concentration in serum L-arginine and in umbilical cord blood,the results indicate low efficiency to the diagnosis of pregnancy hypertension during pregnancy.Conclusion L-arginine level and the development of PIH and body mass index and maternal correlation for the pregnant women.Because the sample size limitations,L-arginine in the diagnosis of PIH also needs to be further research to determine the effectiveness of predicting.
