|
Objectives of Study: |
This study aims to validate the gut microbiota-indole metabolite axis disruption in atherosclerosis patients and to investigate the effect of ILA-producing lactobacilli on elevating ILA levels in healthy subjects. |

药物成份或治疗方案详述: |
健康干预组每日给予一包益生菌(10的9次方 CFU Lr9),健康对照组给予一包安慰剂(麦芽糊精),干预两周。疾病组不采取给药。 |

|
Description for medicine or protocol of treatment in detail: |
Participants in the healthy intervention group received one sachet of probiotic (10? CFU of Limosilactobacillus reuteri Lr9) daily, while those in the healthy control group received one sachet of placebo (maltodextrin) daily for a two-week period. No intervention was administered to the disease group. |
