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. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用CRF与EDC系统协同管理模式: 1. CRF:记录基线人口学、神经心理学量表、实验室检测数据,经双人核对后录入; 2. EDC系统:使用REDCap进行电子化采集,实现实时逻辑校验与审计追踪。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study adopted the collaborative management mode of CRF and EDC system: 1. CRF: baseline demographic data, neuropsychological scales, and laboratory test data were recorded and entered after double check; 2. EDC system: REDCap is used for electronic collection to realize real-time logic verification and audit tracking. |
