研究目的:

采用新型生物信息学技术和16S rRNA二代测序技术研究固定气流阻塞哮喘、可逆气流阻塞哮喘人群与健康对照人群之间肠道微生物群组成和功能差异,并探讨肠道微生物群分布与临床参数之间的相关性,进一步尝试借助新型机器学习算法挖掘有潜力成为固定气流阻塞哮喘的相关生物标志物的肠道微生物群特征。  

Objectives of Study:

Using novel bioinformatics technology and 16S rRNA next-generation sequencing technology to study the differences in gut microbiota composition and function between people with fixed airflow obstruction asthma, reversible airflow obstruction asthma and healthy controls, and to explore gut microbiota distribution and clinical parameters Further attempts were made to explore the gut microbiota signatures that have the potential to be relevant biomarkers for fixed airflow obstruction asthma with the help of novel machine learning algorithms.
