简要总结
The objective of this observational study is to compare the differences in proteomics and gut microbiome between the liver cirrhosis group without hepatic encephalopathy and the hepatic encephalopathy group through proteomics and microbiome analysis, screen out the characteristic proteomics and microbiome of patients with hepatic encephalopathy, guide clinical diagnosis and treatment, and conduct in-depth research on the pathogenesis of hepatic encephalopathy. The main questions it aims to answer are:
Are there any differences in serum proteomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main protein differences? There are differences in the fecal microbiome between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main microbial differences?
This study will screen for the differences in proteomes and gut microbiomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy, and identify the characteristic proteomes and microbiomes of patients with hepatic encephalopathy to guide clinical diagnosis and treatment.
