Clinical Study on the Pathogenesis of Chronic Venous Insufficiency in the Lower Extremities / 中国普外基础与临床杂志

ABSTRACT

Objective To explore the relationship among plasma cytokines’ level, adhesion molecules expression and skin damage in patients with chronic venous insufficiency (CVI) of lower extremities.Methods In 32 patients with CVI and 8 normal individuals as control, blood TNF ?, IL 1? and IL 2R were assayed with ELISA method; serum endothelial cell intercellular adhesion molecule 1(EC ICAM 1), polymorphonuclear CD 18 (PMN CD 18 ) and polymorphonuclear CD 11b (PMN CD 11b ) were assayed with immunohistochemical method; and ultrastructure of diseased veins was examined by electroscope.Results The results showed that the level of plasma TNF ? and IL 1? increased remarkably in Class 2-3 compared with Class 1 and control ( P 0.05) . The index of EC ICAM 1 and PMN CD 11b positively expression increased remarkably in Class 2-3 compared with that in Class 1 and control. The index of PMN CD 18 expression in Class 2-3 and Class 1 was greatly higher than that in control ( P
