摘　　要：目的探讨同型半胱氨酸(Hcy)和阿尔茨海默病(AD)相关性神经丝蛋白(AD7c-NTP)在AD患者诊断中的临床应用。方法选取攀钢集团总医院神经内科自2021年9月至2022年7月收治的82例AD患者作为研究组,再按照认知障碍程度分为轻度组(51例)和中重度组(31例);选取同期健康志愿者82例作为对照组。比较研究组和对照组、轻度组和中重度组血浆Hcy、尿AD7c-NTP水平,采用二元Logistic回归分析并绘制受试者工作特征(ROC)曲线研究血浆Hcy、尿AD7c-NTP以及二者联合对AD的诊断价值。结果研究组血浆Hcy、尿AD7c-NTP水平明显高于对照组,轻度组血浆Hcy、尿AD7c-NTP水平明显低于中重度组,差异均有统计学意义(P<0.05)。ROC曲线分析显示,血浆Hcy、尿AD7c-NTP、二者联合诊断AD的曲线下面积分别为0.812、0.803、0.867,最佳临界值分别为19.5μmol/L、1.545 ng/mL、43.426,约登指数分别为0.549、0.463、0.597,在最佳临界值点对应的敏感度、特异度分别为54.9%、100.0%,96.3%、50.0%,84.1%、75.6%。结论AD患者血浆Hcy、尿AD7c-NTP呈高表达,且认知障碍程度越严重其表达越高,二者联合对AD具有较高的诊断价值。Objective To investigate the clinical application of homocysteine(Hcy)and Alzheimerassociated neuronal thread protein(AD7c-NTP)in the diagnosis of Alzheimer&apos;s disease(AD)patients.Methods Eighty-two AD patients diagnosed and treated in Neurology Department of Pangang Group General Hospital from September 2021 to July 2022 were selected as the study group,and 82 healthy volunteers during the same period were selected as the control group.AD patients of the study group were divided into mild group(51 cases)and moderate to severe group(31 cases)according to the degree of cognitive impairment.The levels of plasma Hcy and urine AD7c-NTP were compared between the study group and the control group,as well as between the mild and moderate to severe groups.The binary Logistic regression analysis and receiver operating characteristic(ROC)curve were used to study the diagnostic value of plasma Hcy,urine AD7c-NTP,and their combination for AD.Results The plasma Hcy and urine AD7c-NTP levels in the study group were significantly higher than those in the control group(P<0.05).The plasma Hcy and urine AD7c-NTP levels in the mild group were significantly lower than those in the moderate to severe group(P<0.05).The ROC curve analysis showed that the area under the curve for diagnosing AD with plasma Hcy,urine AD7c-NTP,and their combination were 0.812,0.803,and 0.867,respectively;the optimal critical values were 19.5μmol/L,1.545 ng/mL,and 43.426,respectively;the Jordan index was 0.549,0.463,and 0.597,respectively.The sensitivity and specificity at the optimal critical points were 54.9%and 100.0%for Hcy,96.3%and 50.0%for AD7c-NTP,and 84.1%and 75.6%for the combination of the two.Conclusion The expression of plasma Hcy and urine AD7c-NTP is high in AD patients,and the more severe the cognitive impairment of AD patients,the higher the expression of plasma Hcy and urine AD7c-NTP;The combination of plasma Hcy and urine AD7c-NTP has high diagnostic value for AD.
