研究目的:

本研究拟选取 Probio-M9 菌株为研究对象, 基于宏基因组学、免疫组学以及代谢组学的研究方法,对益生菌和安慰剂干预前后受试者的血液、粪便、唾液及鼻腔黏液样品进行测定分析。 比较受试者在服用 Probio-M9 前后肠道菌群结构功能、 鼻腔微生物多样性、唾液血液免疫学指标,以及血液粪便生物标志物的变化,研究 Probio-M9 是否具有降低成年人上呼吸道感染发生率、减缓上呼吸道感染程度及缩短持续时间的益生作用。本研究结果或可为益生菌 Probio-M9 作为预防上呼吸道感染的有效方式增加理论支持。  

Objectives of Study:

In this study, the probio-M9 strain is selected as the research object, and the blood, feces, saliva and nasal mucus samples of the subjects before and after the probiotics and placebo intervention are measured and analyzed based on the research methods of macrogenomics, immunoomics and metabonomics.Compare the changes of intestinal flora structure and function, nasal microbial diversity, immunological indicators of saliva and blood, and biomarkers of blood stool before and after taking Probio-M9 to study whether probio-M9 has the probiotic effect of reducing the incidence of upper respiratory tract infection, reducing the degree of upper respiratory tract infection and shortening the duration of upper respiratory tract infection in adults.The results of this study may add theoretical support for probiotics probio-M9 as an effective way to prevent upper respiratory tract infection.

药物成份或治疗方案详述:

本研究拟招募 100 名 20 周岁以上志愿者将不同性别的受试者以 1:1 随机分入益生菌组和安慰剂组,进行为期 6 周的干预实验。其中益生菌组每天服用益生菌制剂,安慰剂组服用不含益生菌的安慰剂制剂, 研究产品以小袋形式分发,两种试验产品的外观 (均为淡粉色粉末)和味道相同。整个实验期间受试者不得知晓分组情况,任何致盲人员都不得与受试者直接接触。分别于 0 周 3 周和 6 周末采集受试者的粪便、鼻腔黏液及唾液样品,于 0 周 6 周末采集受试者血液样品干预期每周进行问卷随访,并通过对采集样品进行宏基因组学、免疫组和代谢组方面的研究,观察干预期间的身体症状、血液免疫指标、肠道微生物结构功能代谢物及相关代谢通路等变化情况。

随机方法(请说明由何人用什么方法产生随机序列):

符合条件的受试者先按性别分层,将不同性别的受试者以 1:1 比率被随机分入益生菌组和安慰剂组。具体操作步骤: ①分组过程分 2 层进行(男性和女性),男性层和女性层实验对象分别为 m 和 n(m和 n 必须是处理组的整倍数,且最好是处理数的 5 倍以上); ②取 m 个随机数从小到大排序,得 R; ③规定 R 所对应的处理,如共 10 名试验人员,则 R1-R5 为 A 组, R6-R10 为B 组; ④将 m 个观察对象分配完毕以后,再按以上方法对下一层 n 个观察对象分组,直到分组结束。

Randomization Procedure (please state who generates the random number sequence and by what method):

The eligible subjects were divided into two groups according to their gender, and the subjects of different genders were randomly divided into probiotics group and placebo group with a ratio of 1:1.
