研究目的:

1. 主要目的:观察健康受试者在甘露聚糖肽药物干预后肠道菌群的变化,我们将特别关注已被报道的对免疫治疗有益的乳酸杆菌属(Lactobacillus),阿克曼菌属(Akkermansia)、瘤胃球菌属(Ruminococcus),双歧杆菌属(Bifidobacterium)的变化。 2. 次要目的:观察受试者服用甘露聚糖肽后粪便代谢产物(特别是鞘脂代谢产物)的变化。  

Objectives of Study:

1. Main objective: To observe the changes in gut microbiota of healthy subjects after intervention with mannan peptide drugs. We will pay special attention to the changes in Lactobacillus, Akkermansia, Ruminococcus, and Bifidobacterium, which have been reported to be beneficial for immunotherapy. 2. Secondary objective: To observe the changes in fecal metabolites (especially sphingolipid metabolites) of subjects after taking mannan peptide.

Sample size:

干预措施:

参与者被告知在研究期间不要改变饮食习惯,也不要服用益生菌、抗生素或任何其他药物。志愿者每天每人服用30mg甘露聚糖肽片(α-甘露聚糖,每片5mg),一日三次,一次10mg,每次间隔时间6h,连续14d。

干预措施代码:

Intervention:

Participants were instructed not to change their dietary habits or take probiotics, antibiotics, or any other medication during the study period. Volunteers take 30mg of alpha mannan peptide tablets (5mg per tablet) three times a day, 10mg each time, with a 6-hour interval between each dose, for 10 consecutive days.
