Abstract:
Objective To observe the expression of intercellular adhesion molecule 1(ICAM-1)and vascular cellular adhesion molecuh 1(VCAM-1)in placenta in patients with hypertensive disorders in pregnancy,investigate their roles in patients with hypertensive disorders in pregnancy and correlation.Methods Fifty-two patients with hypertensive disorders in pregnancy(disease group)were collected,including 11 csses with gestational hypertension(GH),18 cases with mild pre-eelampsia(MP)and 23 cases with gevere pre-eclampsia(SP),26 cases of normal pregnant women as control group.Immunohistochemistry and image analytical technique were employed to show the expression of ICAM-1 and VCAM-1.Results The quantities of ICAM-1 and VCAM-1 expressed in the placental vascular endothelial cell were 78.85%(41/52)and 75.00%(39/52)in disease group,26.92%(7/26)and 23.08%(6/26)in control group,there was a significant difference between the two groups(P<0.01).and those in SP patients[100.00%(23/23)and 100.00%(23/23)]were higher than those in MP patients[77.78%(14/18)and 72.22%(13/18)]and GH patients[36.36%(4/11)and 27.27%(3/11)](P<0.05 or<0.01).The quantities of ICAM-1 and VCAM-1 expressed in the placental villous syncytlotrophoblast were cell 38.46%(20/52)and 44.23% (23/52)in disease group,100.00%(26/26)and 96.15%(25/26)in control group,there was a significant difference between the two groups(P<0.01),and those in SP patients[8.70%(2/23)and 13.04%(3/23)]were lower than those in MP patients[44.44%(8/18)and 50.00%(9/18)]and GH patients[90.91%(10/11)and 100.00%(11/11)](P<0.05 or<0.01).Conclusion Abnormal expression of ICAM-1 and VCAM-1 in the placental vascular endothelial and villous syncytiotrophoblast cell in patients with hypertensive disorders in pregnancy may participate in pathogenic process of vascular endothelial damage of hypertensive disorders in pregnancy.
