研究目的:

本研究旨在明确术前维生素D水平作为儿童POD预测指标的敏感性,并通过基础实验探索其潜在的作用机制,即维生素D与维生素D受体(VDR)结合后,如何调控Nrf2通路并抑制铁死亡,减少海马神经元损伤,从而为小儿术后谵妄的防治提供新的理论依据和干预靶点。  

Objectives of Study:

This study aims to determine the sensitivity of preoperative vitamin D levels as a predictor for pediatric postoperative delirium (POD) and to investigate its potential mechanisms through foundational experiments, specifically how vitamin D binds to the vitamin D receptor (VDR), regulates the Nrf2 pathway, and inhibits ferroptosis, which helps reduce hippocampal neuronal damage. This offers new theoretical foundations and intervention targets for preventing and treating postoperative delirium in children.

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:

标准化采集流程:由经过统一培训的病房护士或医生,按照标准操作程序(SOP)进行采集、处理和临时存储。 数据库提取:临床病例信息(如诊断、实验室结果、影像报告)从医院的电子病历系统(EMR) 和医院信息系统(HIS) 中提取,并经过去标识化处理。 生物样本: 销毁:研究结束后,剩余的生物样本通常将在伦理委员会监督下进行物理销毁(如高压灭菌焚烧)。 数据: 长期保存:所有电子数据在去标识化后,将永久保存于医院的加密服务器或国家级数据库平台(如国家人口健康科学数据中心),用于可能的审计或未来研究。

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

Standardized Collection Process: Samples are collected, processed, and temporarily stored by ward nurses or doctors who have undergone standardized training, following standard operating procedures (SOP). Database Extraction: Clinical case information (such as diagnosis, laboratory results, imaging reports) is extracted from the hospital's electronic medical record system (EMR) and hospital information system (HIS), and de-identified. Biological Samples: Destruction: After the study concludes, remaining biological samples are usually destroyed (e.g., high-pressure sterilization or incineration) under the supervision of an ethics committee. Data: Long-term Storage: All electronic data, after being de-identified, will be permanently stored on the hospital's encrypted servers or national database platforms (such as the National Population Health Science Data Center) for possible audits or future research.
