队列研究 

Study design:

Cohort study 

研究目的:

1.描绘AECOPD继发真菌感染人群的微生物组学、代谢组学和宿主转录组学特征。 2.结合多组学和临床特征,探索预测AECOPD+继发真菌感染患者死亡结局的生物标志物并构建预测模型。 3.基于多组学分析,确立AECOPD继发真菌感染患者气道微生物-代谢物-宿主相互作用分子机制。  

Objectives of Study:

1. Describe the microbiome, metabolomics, and host transcriptome characteristics of the population with secondary fungal infections in AECOPD. 2. Combining multiple omics and clinical features, explore biomarkers for predicting the mortality outcome of AECOPD secondary fungal infection patients and construct a prediction model. 3. Based on multi omics analysis, establish the molecular mechanism of airway microbiota metabolite host interaction in AECOPD patients with secondary fungal infection.
