研究目的:

本研究拟利用7T MRI,揭示缺血性卒中患者急性期Glymphatic系统功能的变化规律,明确Glymphatic系统影像标志物和基因多态性在AIS患者向PSCI转归中的预测价值。本研究开拓性地从脑淋巴循环的角度研究PSCI发生的机制及临床预测模型,研究结果有望为PSCI的预防提供新的策略和干预靶点。  

Objectives of Study:

This study intends to use 7T MRI to reveal the dynamic changes of glymphatic system function in the acute phase of ischemic stroke, and clarify the predictive value of glymphatic system imaging markers and gene polymorphisms in the transition from acute ischemic stroke (AIS) to post-stroke cognitive impairment (PSCI). Pioneeringly, this study investigates the mechanism of PSCI and develops a clinical prediction model from the perspective of brain glymphatic circulation. The findings are expected to provide novel strategies and intervention targets for the prevention of PSCI.

是否共享原始数据:

IPD sharing

是Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

研究结束后6个月原始数据公开日期,先对所有数据进行去标识化处理(隐藏受试者姓名、身份证号等个人标识符,仅保留研究编号关联的研究数据),再通过国家健康医疗大数据中心(https://www.ncmi.cn/)共享,涵盖临床信息、影像数据、基因检测数据、量表评分等所有研究原始数据。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Original data release date, 6 months after the completion of the study. All data will first undergo de-identification processing (with personal identifiers such as the participants' names and ID numbers concealed, and only the study data linked to research serial numbers retained), and then be shared via the National Population Health Data Center (https://www.ncmi.cn/), including all original research data such as clinical information, imaging data, genetic testing data and scale scores.

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:

本研究严格遵循临床研究规范,采用 “CRF 表 + EDC 系统” 双轨模式进行数据采集与管理:首先设计定制化病例记录表(CRF),全面涵盖入组患者的基线临床信息、多时点认知量表评分、7T 磁共振多模态影像指标及基因检测结果;随后将 CRF 数据及时录入电子数据采集系统(EDC),通过系统内置逻辑核查与人工复核双重机制保障数据准确性,同时对所有数据实施去标识化处理与分级权限管理,影像与基因等原始文件按标准格式同步上传至系统加密存储,最终数据将按既定计划在指定平台公开共享。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study strictly complies with clinical research standards, and adopts a dual-track mode of "CRF + EDC system" for data collection and management. First, a customized Case Report Form (CRF) is designed to fully cover the enrolled patients’ baseline clinical information, cognitive scale scores at multiple time points, 7T multimodal magnetic resonance imaging indicators, and genetic testing results. The CRF data are then entered into the Electronic Data Capture (EDC) system in a timely manner. The accuracy of the data is guaranteed by a dual mechanism of built-in logical verification and manual review within the system. Meanwhile, de-identification processing and hierarchical authority management are implemented for all data. Raw files such as imaging and genetic data are synchronously uploaded to the system in standard formats for encrypted storage. The final dataset will be publicly shared on the designated platform in accordance with the established plan.
