Changes of T-helper 1 and T-helper 2 ratio in peripheral blood and decidua in hypertensive disorder complicating pregnancy / 中华妇产科杂志

ABSTRACT

Objective To investigate the role of immune response induced by different T-helper 1 and T-helper 2 (Th1 and Th2) ratio in peripheral blood and decidua from patients with hypertensive disorder complicating pregnancy in the pathogenesis of the disease. Methods Peripheral blood and decidua from 12 non-pregnant women (no deciduas)(normal women group), 12 healthy pregnant women(healthy pregnant women group), 10 patients with gestational hypertension(gestational hypertension group), 25 patients with pre-eclampsia (PE)(including 10 patients with mild pre-eclampsia and 15 patients with severe pre-eclampsia)(pre-eclampsia group). Th1/Th2 ratio in peripheral blood and decidua was determined by flow-cytometrically. Results The ratio of Th1/Th2 in peripheral blood with normal women group is 10.5?1.5, the ratios of Th1/Th2 in peripheral blood and deciduas with healthy pregnant women group are 9.5 ?2.9 and 7.6?4.6 respectively, those with gestational hypertension group are 12.1?3.4 and 13.1?5.6 respectively, those with pre-eclampsia group are 16.8?3.8 and 26.7 ?9.4 respectively. The ratios of Th1/Th2 in peripheral blood and deciduas with pre-eclampsia group are much higher than those with other groups!, when they are compared with each other, there are statistical difference(P
