摘要 目的探讨神经颗粒素(neurograinin,NG)作为急性颅脑损伤(traumatic injury,TBI)患者外周循环标志物的临床意义。方法收集无锡市101医院急诊收治的TBI患者71例,经头颅电子计算机断层扫描(CT)或磁共振成像(MRI)检查确诊,以85例无锡市中医医院体检正常者作为正常对照组。用ELISA双抗体夹心法检测TBI患者和正常对照组外周血中NG水平,采用凝固法检测凝血酶原时间(PT)、纤维蛋白原(Fib),采用胶乳增强免疫比浊法检测C反应蛋白(CRP),用全自动五分类血液分析仪检测血小板(PLT)数量。结果 TBI患者血清NG水平为850.51(647.96,962.11)pg/m L,正常对照组血清NG水平为612.44(534.44,733.9)pg/m L,TBI患者血清NG水平显著高于正常对照组(U=36.146,P=0.000)。中型和重型TBI患者NG水平高于轻型TBI患者,但差异无统计学意义(P>0.05)。原发性颅脑损伤组血清NG水平高于继发性颅脑损伤组,但差异无统计学意义(P>0.05)。TBI患者的年龄、性别、Glasgow积分与血清NG水平无直接关系,而PLT、PT、国际化标准比率(INR)及CRP则是影响NG的主要因素。结论 NG在TBI患者血清中的表达升高,该指标联合凝血功能检测可能对判断TBI患者严重程度和进展具有一定意义。
