Study phase:

N/A

研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

1. 建立AAAD患者临床病历资料及生物学样本数据库:前瞻性收集AAAD患者的临床病历资料,采集患者的外周血单个核淋巴细胞(peripheral blood mononuclear cell,PBMC)及血浆样本,构建AAAD患者的临床病历资料及生物学样本数据库。 2. 揭示AAAD患者发生术后感染的分子机制:通过对AAAD患者的生物学样本进行多模态组学分析,包括:细胞因子芯片、免疫细胞图谱、单细胞测序、全转录组测序、蛋白组学分析及代谢组学分析,深入挖掘AAAD患者发生术后感染的分子机制。 3. 构建AAAD患者术后感染的预测模型:通过机器学习算法对患者的临床病历资料和生物学样本多模态组学测序结果进行整合和分析,构建AAAD患者术后感染的预测模型,并在临床患者中进行验证。  

Objectives of Study:

1. Establishment of a clinical medical record and biological sample database for AAAD patients: Prospectively collect clinical medical records of patients with acute ascending aortic dissection (AAAD), collect peripheral blood mononuclear cells (PBMC) and plasma samples, and construct a clinical medical record and biological sample database for AAAD patients. 2. Revealing the molecular mechanism of postoperative infection in AAAD patients: Perform multimodal omics analysis on biological samples of AAAD patients, including cytokine array, immune cell profiling, single-cell sequencing, whole-transcriptome sequencing, proteomic analysis, and metabolomic analysis, to deeply explore the molecular mechanism underlying postoperative infection in AAAD patients. 3. Construction of a prediction model for postoperative infection in AAAD patients: Integrate and analyze patients' clinical medical records and multimodal omics sequencing results through machine learning algorithms, construct a prediction model for postoperative infection in AAAD patients, and verify it in clinical patients.
