【摘要】：目的探讨APOEε4等位基因与尿AD7c-NTP联合检测在阿尔兹海默病(AD)早期诊断预防中的价值。方法根据中国精神障碍分类与诊断标准第三版(CCMD-3)有关精神分裂症及轻度阿尔兹海默病的诊断标准,选取76例临床诊断疑似AD患者(PAD组),另选90例健康者作为对照组。对比两组APOEε4等位基因频率和尿AD7c-NTP含量对AD的诊断价值。结果 (1)APOEε4等位基因表达频率在PAD组显著高于对照组(P≤0.05);(2)尿AD7c-NTP在PAD组中的含量较对照组显著升高(P≤0.01);(3)对APOEε4、AD7c-NTP及二者联合检测进行比较发现,APOEε4对AD诊断的灵敏度、特异度、阳性预测值、阴性预测值、约登指数分别为:44.64%、88.33%、78.13%、63.10%、0.33;尿AD7c-NTP诊断的灵敏度、特异度、阳性预测值、阴性预测值、约登指数分别为:78.57%、83.33%、81.48、80.65%、0.62;APOEε4与AD7c-NTP联合检测的诊断灵敏度、特异度、阳性预测值、阴性预测值、约登指数分别为:91.18%、91.55%、83.78%、95.58%、0.82。结论 APOEε4等位基因与尿AD7c-NTP联合检测是监测及诊断AD早期病变的较好指标,提升二者单独应用时的预测价值,宜作为AD易发人群鉴别和早期诊断的生物标记物。
[Abstract]:Objective to investigate the value of combined detection of APOE 蔚 4 allele and urinary AD7c-NTP in early diagnosis and prevention of Alzheimer's disease (AD). Methods according to the diagnostic criteria of schizophrenia and mild Alzheimer's disease (CCMD-3), 76 suspected AD patients (PAD group) and 90 healthy persons (control group) were selected. The diagnostic value of APOE 蔚 4 allele frequency and urinary AD7c-NTP content in AD was compared between the two groups. Results (1) the frequency of APOE 蔚 4 allele expression in the PAD group was significantly higher than that in the control group (P 鈮，
