Outcome Measures

Primary Outcomes (5)

  • Participants' characteristics

    To obtain participants' characteristics, including age, gender, alcohol consumption, body mass index, smoking, medications.

    1 day

  • Microbial community structure

    To assess participants' microbiome composition in faecal samples, inclding microbial diversity and richness.

    1 day

  • Metabolite composition

    To measure the metabolite profiles in participants' faecal samples and serum samples, involving Bile acids, short chain fatty acids, TMAO and related metabolites, amino acids, fatty acids, organic acids, flavonoids, plant hormones, neurotransmitters.

    1 day

  • Microbes-metabolites correlations

    To assess the correlations of gut microbiota and metabolites by Spearman's correlation analysis.

    1 day

  • Response of target organ

    To find the effects of microflora and metabolites on target organ by transcriptome sequencing.

    1 day
