研究目的: |
本研究旨在探究心脏手术患者外周血单个核细胞(PBMCs)中铁死亡的发生情况及其激活程度,并明确其是否与术后谵妄(POD)的发生发展存在显著关联。 通过阐明PBMCs铁死亡在POD中的潜在作用机制,本研究期望为心脏术后谵妄的早期预警、风险分层及潜在干预靶点提供新的理论依据和实验基础。 |

|
Objectives of Study: |
The purpose of this study was to investigate the occurrence and activation of ferroptosis in peripheral blood mononuclear cells ( PBMCs ) of patients undergoing cardiac surgery, and to determine whether it is significantly associated with the occurrence and development of postoperative delirium ( POD ). By elucidating the potential mechanism of ferroptosis of PBMCs in POD, this study is expected to provide new theoretical basis and experimental basis for early warning, risk stratification and potential intervention targets of delirium after cardiac surgery. |

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: |
1.数据录入:使用Epidata 3.1进行双人独立录入,设置逻辑校验规则(如数值范围、逻辑一致性),减少录入错误。电子病例报告表(eCRF)涵盖所有观察指标,包括开放字段(如不良事件描述)和标准化选项(如CAM-ICU结果)。 2.数据存储与安全: 原始数据:纸质记录(如手术记录、实验室原始数据)扫描为PDF存档,与电子数据一一对应。 数据库:加密存储于医院内部服务器,定期备份至独立硬盘,访问权限仅限于研究组成员。 隐私保护:患者姓名、住院号等敏感信息以匿名编码替代(如POD-001、Control-001)。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1.Data entry: Use Epidata 3.1 for two-person independent entry, set logical verification rules ( such as numerical range, logical consistency ), and reduce entry errors. An electronic case report form ( eCRF ) covers all observed indicators, including open fields ( such as adverse event descriptions ) and standardized options ( such as CAM-ICU results ). 2.Data storage and security: Raw data : Paper records ( such as surgical records, laboratory raw data ) are scanned as PDF files, which correspond to electronic data one by one. Database : encrypted storage in the hospital 's internal server, regularly backed up to an independent hard disk, access rights are limited to the study group members. Privacy protection : Patient name, hospital number and other sensitive information are replaced by anonymous coding ( such as POD-001, Control-001 ). |
