ABSTRACT
Objective@#To explore the differences of thromboinflammatory response between healthy pregnancy and preeclampsia (PE) and provide potential strategies for diagnosis and prevention of PE. @*Methods@#The antibody microarray was prepared to detect plasma protein expression profile of non-pregnant women, healthy pregnant women and preeclampsia patients. The differentially expressed proteins were identified and analyzed. @*Results@#The levels of 37 proteins were significantly different between non-pregnant and healthy pregnant women, among which 16 proteins were increased, such as disintegrin, metalloproteinase domain-containing protein 12 and C-C motif chemokine 2, while 21 proteins were decreased, such as GM-CSF and apolipoprotein F. The levels of 27 proteins were significantly different between healthy pregnant women and preeclampsia patients, among which 16 proteins were increased, such as GM-CSF and VEGFR2 and 11 proteins were decreased, such as tumor necrosis factor-related apoptosis-inducing ligand and interferon Omega 1. Further analysis found that PE patients group presented more complicated changes compared with healthy pregnant women. PE group included more significantly increased proteins which involved in inflammation and immune responses and elevated levels of acute phase reaction, while the levels of more anti-inflammation cytokines decreased significantly. In the plasma of PE patients more proteins participating thrombosis and complement reaction increased significantly. Also, renin level was significantly dropped and VEGFR2 was elevated. @*Conclusion@#More serious inflammatory response, hypercoagulable status and imbalance of angiogenesis and anti-angiogenesis may exist in PE, which should be helpful for further improving potential strategies in diagnosis and prevention of PE.
