研究目的: |
本研究旨在阐明维生素D在阿尔茨海默病(AD)病理演变中的阶段特异性调控作用,重点解决以下核心问题: 1、揭示维生素D的动态水平与AD核心病理(Aβ沉积速率、Tau蛋白空间扩散)的时序关联,建立血清维生素D浓度与Aβ-PET SUVR年增长率、Tau-PET扩展的剂量-效应关系,并探索其通过IL-6/NF-κB通路介导神经炎症的分子机制; 2、确立精准干预靶点,针对不同APOE ε4基因型人群,确定维生素D最优维持阈值,开发基于AD病理分期的个体化维生素D补充策略。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to elucidate the stage-specific regulatory role of vitamin D in the pathological progression of Alzheimer's disease (AD), addressing two primary objectives: 1. To delineate the temporal association between dynamic vitamin D levels and core AD pathologies, specifically quantifying the dose-response relationships of serum vitamin D concentrations with: Annual increase rates of Aβ-PET SUVR (standardized uptake value ratio);Spatial propagation of Tau-PET signal distribution.Concurrently, it will investigate the molecular mechanism through which vitamin D modulates neuroinflammation via the IL-6/NF-κB signaling pathway. 2. To establish precision intervention targets by:Determining optimal vitamin D maintenance thresholds stratified by APOE ε4 genotype;Developing individualized vitamin D supplementation strategies aligned with AD pathological stages. |

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: |
数据采集流程:研究数据包含临床信息、生物样本数据和影像数据三类。临床信息通过纸质问卷收集,涵盖参与者基本信息、AD量表等内容,由研究者核对确保准确;生物样本数据为血液样本,由专业医护人员采集,所有样本采集后按规定温度和时间要求进行处理和保存; 影像数据包括MRI、 AβPET/CT及tau PET/CT DICOM原始数据。 数据管理体系:在数据存储方面,纸质文件存放于带锁文件柜,仅限授权人员接触;电子数据加密存储于医院专用,并每日备份至异地云端。 数据安全上,个人信息进行匿名化处理,生物样本标签仅标注研究编号,数据传输全程加密。权限管理实行分级制度,主研人拥有数据查看、导出和分析权限,修改需审批;研究助理仅可录入和初步整理数据、数据使用遵循内部仅限本研究团队科研分析、外部共享需获参与者书面同意且符合法规要求的原则。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection process: The research data includes three categories: clinical information, biological sample data, and imaging data. Clinical information is collected through paper questionnaires, covering participants' basic information, AD scales, etc., which are checked by researchers to ensure accuracy. Biological sample data refers to blood samples, which are collected by professional medical staff. All samples are processed and stored in accordance with specified temperature and time requirements after collection. Imaging data includes MRI, Aβ PET/CT, and tau PET/CT DICOM raw data. Data management system: In terms of data storage, paper documents are stored in locked file cabinets, accessible only to authorized personnel; electronic data is encrypted and stored in a hospital-specific system, with daily backups to an off-site cloud. For data security, personal information is anonymized; biological sample labels only indicate research numbers; and data transmission is encrypted throughout the process. A hierarchical system is implemented for permission management: principal investigators have the authority to view, export, and analyze data, with modifications requiring approval; research assistants can only enter and initially organize data. The principle for data usage is that internal use is limited to scientific research analysis within the research team, and external sharing requires written consent from participants and compliance with regulatory requirements. |
