研究目的: |
主要目的: 1. 对入组样本进行 Bulk RNA-seq 转录组测序,筛选脓毒症特异性 mRNA 诊断标志物,评估其对 ICU 早期脓毒症的诊断效能;基于 mRNA 表达谱建立脓毒症分子风险分型体系,明确各分型的免疫生物学特征、临床表现差异与预后风险等级。 2. 整合转录组测序、开源数据库及前期研究筛选的核心指标,建立并优化针对脓毒症核心靶标的 RT-LAMP 快速检测方法,验证其诊断准确性、特异性、重复性并构建适配床旁场景的脓毒症快速诊断模型。 3. 整合开源数据库及前期研究筛选的核心指标,通过 RPM 和代谢组学筛选脓毒症特异性血浆和尿液诊断标志物,并在免疫方法(ELISA)上完成蛋白/代谢水平验证,构建脓毒症联合诊断模型,完成内部验证与效能评估。 次要目的: 1. 明确核心诊断标志物的 mRNA/蛋白/代谢物表达水平与脓毒症患者 28 天全因死亡率、器官功能损伤程度、脓毒症休克发生率以及不同亚组(感染部位、病原类型、器官损伤程度、免疫状态、SOFA 分层等)的相关性。 2. 解析脓毒症不同分子分型的免疫炎症通路特征,为后续精准治疗靶点筛选提供理论依据。 |

Objectives of Study: |
Primary objectives: 1. Perform bulk RNA-seq transcriptome sequencing on enrolled samples to screen for sepsis-specific mRNA diagnostic markers and evaluate their diagnostic performance for early sepsis in the ICU; establish a molecular risk stratification system for sepsis based on mRNA expression profiles, clarifying the immunobiological characteristics, clinical presentation differences, and prognostic risk levels of each subtype. 2. Integrate transcriptome sequencing, open-source databases, and core indicators screened from previous studies to develop and optimize a rapid RT-LAMP detection method targeting core sepsis markers, validating its diagnostic accuracy, specificity, reproducibility, and constructing a rapid bedside sepsis diagnostic model. 3. Integrate open-source databases and core indicators screened from previous studies to select sepsis-specific plasma and urine diagnostic markers through RPM and metabolomics, and verify protein/metabolite levels using immunological methods (ELISA), to construct a combined sepsis diagnostic model with internal validation and performance evaluation. Secondary objectives: 1. Clarify the correlation between mRNA/protein/metabolite expression levels of core diagnostic markers and 28-day all-cause mortality, organ dysfunction severity, occurrence of septic shock, and different subgroups (infection site, pathogen type, degree of organ damage, immune status, SOFA stratification, etc.) in sepsis patients. 2. Analyze the immune-inflammatory pathway characteristics of different molecular subtypes of sepsis to provide a theoretical basis for the subsequent screening of precise therapeutic targets. |

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. 病例记录表 (CRF):本研究设计了标准化纸质 CRF。CRF 包含研究对象基本信息、入组标准核查、基线资料、观察指标及结局指标等内容。所有研究人员均经过统一培训,严格按照 CRF 填写说明进行数据采集。 2. 电子数据采集和管理系统 (EDC):采用 Excel 进行电子数据管理。由 2 名研究人员独立将纸质 CRF 数据录入 Excel 表格,进行双录入比对。对不一致的数据与原始 CRF 进行核对修正。数据录入完成后进行逻辑核查和范围核查,删除重复数据,处理缺失值。最终数据集加密存储,每日备份至移动硬盘和云端,设置访问密码,仅限项目负责人和数据管理员访问。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Case Record Form (CRF): A standardized paper CRF was designed for this study. The CRF includes basic information of study subjects, eligibility verification, baseline data, observation indicators and outcome indicators. All researchers have received unified training and collect data strictly in accordance with the CRF filling instructions. 2. Electronic Data Capture (EDC) System: Excel is used for electronic data management. Two researchers independently enter data from paper CRFs into Excel spreadsheets and perform double entry verification. Inconsistent data are corrected by checking against the original CRFs. After data entry is completed, logical checks and range checks are performed, duplicate data are deleted, and missing values are processed. The final dataset is stored encrypted, backed up daily to external hard drives and the cloud, protected by access passwords, and only accessible to the project leader and data manager. |
