Analysis of relationship between plasma TNF-α,IL-6 levels and brain edema caused by hypertensive intracerebral hemorrhage / 中国基层医药

ABSTRACT

Objective To explore the relationship between plasma Tumor necrosis factor-alpha(TNF-α),Interleukin-6(IL-6) levels and brain edema caused by hypertensive intracerebral henorrhage.Methods 62 patients with hypertensive intrscerebral hemorrhage( the observation group) and 50 healthy persons( the control group) were selected.The expression of plasma TNF-α and IL-6 were determined by ELISA pre-therapy and 1d,3d,7d,14d after treatment in two groups;The volume of cerebral edema was measured by CT.The relationship between plasma TNF-α,IL-6 levels and brain edema caused by hypertensive intracerebral hemorrhage were analyzed.Results Before treatment,the levels of TNF-α and IL-6 in the observation group were( 15.62 ±9.49)μg/L and (67.47 ±6.31 )ng/L,which were significandy higher than(8.28 ± 3.36) μg/L and(31.02 ± 3.51 ) ng/L of the control group( t =9.17,64.28,P =0.01 ),and Spearman analysis showed that the levels of TNF-α and IL-6 were positively correlated with the volume of cerebral edema(r=0.934,P=0.02;r=0.922,P =0.026).Conclusion There was an up-regulation of TNF-α and IL-6 levels in the plasma of patients with hypertensive intracerebral hemorrhage.TNF-α and IL-6 may promote the formation of cerebral edema during the course of hypertensive intracerebral hemorrhage.
