Brief Summary

major objective This multicenter, prospective cohort study aims at evaluating the predictive value of microbiome ,proteomics and serum markers in preeclampsia. secondary objective to evaluate the value of microbiome,proteomics and serum markers in assessing pregnancy outcome (complications during pregnancy and delivery, delivery) and neonatal prognosis.

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.

Other: Observational studies, The diagnosis was preeclampsia

Interventions

Observational studies, The diagnosis was preeclampsia

Pregnant women and Follow-up of pregnant women's newborns
