研究目的:

主要研究目的: 探讨脓毒症患者早期血细胞(如白细胞、淋巴细胞等)数量和功能变化与预后的关系,旨在发现潜在的生物标志物,帮助预测脓毒症患者的预后。 次要研究目的: 1、评估血细胞动态变化是否能够作为脓毒症患者早期预警信号,从而指导个体化治疗。 2、研究血细胞功能变化与脓毒症严重程度(如多器官功能衰竭、感染源、死亡率等)的相关性。 3、探索血细胞功能变化的分子机制,以便为未来的干预措施提供理论依据。  

Objectives of Study:

Primary Research Objective:?? To investigate the relationship between early quantitative and functional changes in blood cells (such as white blood cells, lymphocytes, etc.) and prognosis in sepsis patients, aiming to identify potential biomarkers that can aid in predicting the prognosis of sepsis patients. Secondary Research Objectives:?? 1.To assess whether dynamic changes in blood cells could serve as an early warning signal for sepsis patients, thus guiding individualized treatment. 2.To study the correlation between functional changes in blood cells and sepsis severity (e.g., multiple organ failure, infection source, mortality rate). 3.To explore the molecular mechanisms underlying the functional changes in blood cells, in order to provide a theoretical basis for future therapeutic strategies.

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:

本研究采用标准化的数据采集与管理流程,严格遵循临床研究规范。临床数据采集包括每日生命体征监测(体温、心率、血压、呼吸频率)、SOFA评分动态记录(基线、第1/3/7天)、抗生素使用方案及实验室检查结果(血常规、生化指标、炎症标志物)的收集。生物样本采集使用EDTA抗凝全血(紫头管)3-5ml,样本标注研究ID和采集时间,4小时内送检至中心实验室(2-8℃保存)。随访数据通过医院信息系统、标准化电话随访问卷及疾控中心死亡登记系统三重验证获取。建立数据库,设置逻辑校验和自动备份功能,实施双人独立录入、随机抽查及审计追踪等质控措施。所有数据均进行匿名化处理(研究ID替代个人信息),实行分级权限管理。研究结束后的样本销毁需经伦理审批。

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

This study employs standardized data collection and management procedures, strictly adhering to clinical research protocols. Clinical data collection includes daily vital sign monitoring (temperature, heart rate, blood pressure, respiratory rate), dynamic SOFA score recording (baseline, days 1/3/7), antibiotic treatment regimens, and laboratory test results (complete blood count, biochemical indicators, inflammatory markers). Biological sample collection utilizes 3-5ml EDTA-anticoagulated whole blood (purple-top tubes), with samples labeled with study ID and collection time, and transported to the central laboratory within 4 hours (stored at 2-8°C). Follow-up data is obtained through triple verification via hospital information systems, standardized telephone questionnaires, and disease control center mortality registry systems. A dedicated database is established with logical validation and automatic backup functions, implementing quality control measures including dual independent data entry, random sampling, and audit trails. All data undergoes anonymization (replacing personal information with study IDs) with tiered access control. Sample destruction upon study completion requires ethics committee approval.
