Proteomics/Modifier Based on Mass Spectrometry Reveals the Pathogenesis of Eclampsia During Pregnancy and the Screening of Disease Markers

April 2, 2021 updated by: Xiaoke Wu, Heilongjiang University of Chinese Medicine
Pregnancy-induced hypertension is a unique abnormal blood pressure disease in women during pregnancy, including eclampsia, preeclampsia, pregnancy-induced hypertension, chronic hypertension and so on. Eclampsia can lead to convulsions, proteinuria, multiple organ failure, and eventually death. It is a very serious disease in women, and the incidence of pregnancy-induced hypertension during pregnancy is between 4% and 10%. The incidence of eclampsia ranges from 2% to 5%. Studies have shown that there are about 60,000 cases of stillbirth or stillbirth due to eclampsia every year worldwide. At present, there are many theories about the pathogenesis of eclampsia, such as oxidative stress theory, maternal and fetal interaction theory, immune imbalance theory, heredity theory and so on.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proteomics and acetylation modification analysis of placenta, blood, urine, and cervical secretions
Time Frame: 2023-08
Proteomics analysis is carried out using the TMT labeling quantitative method, the significantly differentially expressed proteins and modification sites are screened out, and then the proteins with significantly different changes are used as disease signs; Through the GO classification analysis of the protein, the subcellular structure location analysis of the protein is carried out, and the mitochondrial-related protein and skeleton protein are concerned. Through the enrichment of acetylated antibody modified protein-peptide, the changes of modified protein and its regulatory mechanism were analyzed, and the regulatory role of acetylated protein in mitochondrial metabolism and immune response was found. This study uses the Mfuzz clustering method to perform clustering analysis of the expression profile of proteins, the pathogenesis of the disease through protein enrichment analysis, pathway analysis, and interaction analysis are explored.
