血浆可溶性P-选择素与儿童偏头痛关系的研究

摘要

Objective To study the relationship between the level of plasma soluble P-selectin and pediatric migraine. Methods ABC-ELISA method was used to detect the soluble P-selectin levels in migraine patients (migraine group), migraine patients under control (control group) and healthy children (healthy control group). Transcranial Doppler ultrasound (TCD) and the platelet count were performed. Correlation of P-selectin and platelet count was analyzed. Results Plasma soluble P-selectin level in migraine group was significantly higher than that in the control group and the healthy control group (both P < 0.05). Significant difference was not found between control group and healthy control group (P > 0.05). TCD showed cerebral vasospasm more frequent in the migraine group than the control group, with significant difference (P < 0.05). Blood examination revealed that platelet count of migraine group is higher than that of the control group and the healthy control group, with significant differences (P < 0.05). When migraine was under control, the level of plasma soluble P-selectin reduced to normal and the frequncy of cerebral vasospasm and platelet counts were also within normal range. Plasma soluble P-selectin level and platelet count were positively correlated (r = 0.996, P < 0.01). Conclusions Plasma soluble P-selectin increased in migraine children, the incidence of cerebral vasospasm was significantly increased. Plasma soluble P-selectin level and platelet count were positively correlated. Plasma soluble P-selectin can be used as one of the indicators of diagnosis, treatment and efficacy evaluation in pediatric migraine.%目的 研究血浆可溶性P-选择素水平与儿童偏头痛的关系.方法 采用ABC-ELISA法检测偏头痛组、偏头痛病情控制组及健康对照组儿童可溶性P-选择素的水平、经颅多普勒(TCD)和外周血血小板计数,并进行P-选择素与血小板计数的相关性分析.结果 偏头痛组患儿血浆可溶性P-选择素水平明显高于病情控制组及健康对照组,差异有统计学意义(F=111.067,P<0.05);病情控制组与正常对照组比较,差异元统计学意义(P>0.05);TCD检测显示偏头痛组患儿脑血管痉挛发生率明显高于病情控制组患儿,差异有统计学意义(X~2=23.08,P<0.05);血常规检查显示偏头痛组血小板计数高于病情控制组及健康对照组,差异有统计学意义(X~2=22.22,P<0.05);病情控制组患儿血浆可溶性P-选择素水平降至正常,脑血管痉挛及血小板数升高的发生率均降至正常水平.血浆可溶性P-选择素水平与血小板计数呈正相关(r=0.996,P<0.01).结论 儿童偏头痛血浆可溶性P-选择素增高,脑血管痉挛发生率明显增高.血浆可溶性P-选择素与血小板计数呈正相关.血浆可溶性P-选择素可作为儿童偏头痛诊断、治疗及疗效评价的指标之一.
