Outcome Measures
Primary Outcomes (3)
microbiome
To evaluate the predictive value of microbiome in preeclampsia. To observe the changes of microbiome in pregnant women with preeclampsia from 11-14 weeks of gestation to two years postpartum.The microbial composition of the stool samples was determined by 16S rRNA (ribosomal ribonucleic acid) gene sequencing analysis and metagenomics.
34 months
proteomics
To evaluate the predictive value of proteomics in preeclampsia. To observe the changes of urine and serum proteomics in pregnant women with preeclampsia from 11-14 weeks of gestation to two years postpartum. proteomics is the large-scale study of small or big molecules, such as protein,polypeptide.
34 months
metabonomics
To evaluate the predictive value of metabonomics in preeclampsia. To observe the changes of serum metabonomics in pregnant women with preeclampsia from 11-14 weeks of gestation to two years postpartum. Metabolomics is the large-scale study of small molecules, such as fatty acids, bile acids, lipid mediators and others.
