研究目的:

验证动脉粥样硬化患者存在肠道菌群-吲哚类代谢紊乱;探究产吲哚乳酸乳杆菌对健康人群吲哚乳酸水平的影响。  

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.

Inclusion criteria

1. Inclusion criteria for atherosclerosis patients (1) Confirmation of >=50% stenosis in the coronary arteries by coronary CT angiography (CTA) or digital subtraction angiography (DSA); (2) 18 years of age or older; (3) Patient voluntarily agrees to participate in the study and signs the informed consent form. 2. Inclusion criteria for healthy individuals (1) BMI within the normal range of 18.5–23.9; (2) No history of metabolic diseases, cardiovascular diseases, or severe systemic illnesses; (3) Age >= 18 years; (4) Willingness to participate in the study and provision of informed consent; (5) No use of antibiotics or probiotic supplements within the past month.

排除标准:

1.近1个月内使用过抗生素或接受肠道菌群移植; 2.近1月内使用益生菌补充剂; 3.严重全身性疾病,如晚期恶性肿瘤、活动性感染、终末期肝肾功能不全; 4.长期使用全身性糖皮质激素、免疫抑制剂。

Exclusion criteria:

1. Use of antibiotics or undergoing fecal microbiota transplantation within the past month; 2. Use of probiotic supplements within the past month; 3. Severe systemic diseases, such as advanced malignant tumors, active infections, or end-stage liver and kidney dysfunction; 4. Long-term use of systemic glucocorticoids or immunosuppressants.
