ABSTRACT
Objective: To explore the characteristics of cell adhesion molecules (sICAM-1, sP-selectin) changes on inflammatory response during cardiopulmonary bypass, and observe the effect of intervention therapy with ligustrazine on changes of cell adhesion molecules. Methods: 32 cases of congenital heart disease were divided at random into ligustrazine group (20 cases) and control group (12 cases). Ligustrazine (5mg/kg) were added to extracorporeal circulation machine in ligustrazine group. In each group, arterial blood samples were taken at the following time-points after induction of anesthesia, 15 minutes after the start of CPB, and 2 hours, 6 hours, 12 hours, 24 hours after CPB. sICAM-1, sP-selection was measured by double antibodies sandwich enzyme-linked immunosorbent assay (ELISA). Results: Plasma levels of both adhesion molecules in both groups at baseline were in normal ranges. After CPB, levels of adhesion molecules were significantly increased in both groups. The plasma levels of sICAM-1, sP-selectin in control group were higher than in ligustrazine group (P
