Study design:

Case-Control study 

研究目的:

(1)通过蛋白质组学技术检测早期AD患者与健康对照者血浆中的差异表达蛋白谱,发掘潜在的新型AD血浆生物标志物。 (2)通过ELISA技术在扩大样本队列中验证候选差异蛋白的表达模式,分析其与AD(从认知正常到MCI至AD)的动态变化关系。 (3)基于经典AD生物标志物(p-tau217、p-tau181、Aβ42/40)开展以下深度分析:通过相关性分析揭示新发现蛋白与AD经典标志物的生物学关联;采用ROC曲线分析比较新血浆生物标志物与经典标志物对AD及MCI的诊断效能差异;探索新老标志物组合模型对AD早期诊断的协同提升效应。  

Objectives of Study:

(1) To discover novel plasma biomarkers for AD by profiling differentially expressed proteins in early-stage AD patients versus healthy controls using proteomics. (2) To perform large-scale validation of candidate proteins via ELISA and assess their longitudinal associations with AD progression (normal → MCI → AD). (3) To conduct in-depth analyses based on classical AD biomarkers (p-tau217, p-tau181, Aβ42/40), including: Correlation analyses to elucidate biological relationships between newly identified proteins and established AD biomarkers; ROC curve analyses to compare diagnostic performance (AD/MCI discrimination) between novel plasma biomarkers and classical markers; Exploration of combinatorial models (novel + classical biomarkers) to evaluate synergistic effects for early AD detection.
