摘要 目的观察阿尔茨海默病(AD)患者α-突触核蛋白、β-淀粉样蛋白1-42(Aβ1-42)、总牛磺酸(T-tau)、磷酸化牛磺酸(P-tau)、轻链蛋白(NF-L)水平变化,并探讨其临床意义。方法 AD患者43例(AD组),血管性痴呆(VD)患者51例(VD组),健康体检者30例(对照组),检测各组脑脊液α-突触核蛋白、Aβ1-42、T-tau、P-tau、NF-L,应用多因素分析联合5个指标区分AD和VD的灵敏度、特异度。结果与对照组比较,AD组脑脊液α-突触核蛋白、T-tau、P-tau、T-tau/P-tau、NF-L水平升高,Aβ1-42水平降低(P均<0.05);与对照组比较,VD组脑脊液α-突触核蛋白、T-tau、P-tau、T-tau/P-tau、NF-L水平升高(P均<0.05);与VD组比较,AD组脑脊液Aβ1-42、T-tau、T-tau/P-tau水平升高(P均<0.05)。联合5个指标区分AD和VD的灵敏度为93%、特异度为88%。结论α-突触核蛋白、Aβ1-42、T-tau、P-tau、NF-L在AD中表达升高或降低,联合检测五种指标有可能早期诊断AD及鉴别VD。
