Study design:

Cross-sectional 

研究目的:

探寻关键肠道菌群及其活性代谢物质对慢加急性肝衰竭的调控(加剧或者改善)作用。其次,探寻关键肠道菌群的丰度变化及其活性代谢物质含量变化与慢加急性肝衰竭进展的临床相关性。  

Objectives of Study:

Explore the regulatory (exacerbating or improving) effects of key gut microbiota and their active metabolites on chronic acute liver failure. Secondly, explore the clinical correlation between changes in the abundance and active metabolite content of key gut microbiota and the progression of chronic acute liver failure.
