ABSTRACT

Objective To investigate the effect ofvalproate acid(VAP) on the activity ofneutrophils in children with epilepsy and its clinical significance.Methods A total of 34 cases of children with epilepsy(epilepsy group) were enrolled in this study.Another 30 healthy children were as control group.The activation rate of neutrophils was detected by flow cytometry.The levels of serum high sensitivity-C reactive protein(hs-CRP) were measured by latex enhanced immunoturbidimetric analysis.The levels of serum tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay analysis.Results The activation rate of neutrophils had no significant difference between epilepsy group before treatment and control group (P ＞ 0.05).The activation rate of neutrophils after treatment of 6,12 months in epilepsy group was higher than that in control group [(12.36 ± 4.72)％,(15.87 ± 5.68)％ vs.(5.32 ± 1.41)％,P ＜ 0.01].The activation rate of neutrophils after treatment of 12 months was higher than that after treatment of 6 months in epilepsy group (P ＜ 0.05).There was no significant difference in the levels of serum hs-CRP,TNF-α and IL-6 between epilepsy group before treatment and control group (P ＞ 0.05).The levels of serum hs-CRP,TNF-α and IL-6 after treatment of 6,12 months in epilepsy group were higher than those in control group [(3.64 ± 1.22),(6.96 ± 2.64) mg/L vs.(1.46 ± 0.27) mg/L,(74.72 ± 22.58),(96.67 ± 30.25) ng/L vs.(31.72 ± 12.16) ng/L,(32.59 ± 8.45),(46.74 ± 12.16) ng/L vs.(15.36 ± 4.45)ng/L,P ＜ 0.01],and those after treatment of 12 months were higher than those after treatment of 6 months (P ＜ 0.05).The activation rate of neutrophils was positively related with the serum levels of hs-CRP,TNF-αand IL-6 (r =0.328,0.402,0.344,P ＜ 0.05).Conclusions The high activation rate of neutrophils is found in children with epilepsy.The abnormal activation of neutrophils makes the body undergo high oxidative stress status.
