Cohort study 

研究目的:

本研究旨在构建脓毒症免疫动态回顾性队列(含脓毒症组/非脓毒症感染组/健康对照组),通过多时间点临床数据与外周血样本,系统性评估现有诊断标准(如SOFA评分)在时序预警中的敏感性缺陷,解析感染源异质性对免疫表型轨迹的影响,明确构建基于宿主-病原体互作动态网络的分层模型必要性;基于该队列整合质谱流式(CyTOF)、单细胞转录组、蛋白组与代谢组学技术,识别感染源特异性共调控模块,构建可区分疾病进展阶段(代偿期/失代偿期)的跨组学生物标志物组合,通过独立队列验证分层预警模型预后效能,并筛选调控免疫检查点或细胞焦亡通路的关键靶向分子。  

Objectives of Study:

This study aims to construct a retrospective cohort of sepsis immune dynamics (including sepsis/non-septic infection/healthy control groups) to systematically evaluate the sensitivity limitations of current diagnostic criteria (e.g., SOFA score) in temporal early-warning and dissect the impact of pathogen heterogeneity on immune phenotypic trajectories through multi-timepoint clinical data and peripheral blood samples, thereby determining the necessity of establishing a stratified model based on dynamic host-pathogen interaction networks. Leveraging this cohort, we integrate mass cytometry (CyTOF), single-cell transcriptomics, proteomics, and metabolomics to identify pathogen-specific co-regulatory modules, develop cross-omics biomarker panels distinguishing disease progression stages (compensated/decompensated phases), validate the prognostic efficacy of the stratified early-warning model in an independent cohort, and screen key target molecules regulating immune checkpoints or pyroptosis pathways.
