研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

1.使用宏基因组高通量测序技术全面表征VAP患者口腔微生物组(细菌及真菌)及相互作用,及揭示口腔微生物组(细菌及真菌)与VAP患者的预后关联性。 2.揭示口腔微生物与宿主的互作机制。 3.揭示口腔微生物组与炎症反应的关联性。  

Objectives of Study:

1. Use metagenomic high-throughput sequencing technology to comprehensively characterize the oral microbiome (bacteria and fungi) and their interactions in VAP patients, and to reveal the association between the oral microbiome (bacteria and fungi) and the prognosis of VAP patients. 2. Uncover the interaction mechanisms between the oral microbiota and the host. 3. Reveal the correlation between the oral microbiome and inflammatory responses.
