研究目的:
|
探讨口服、含服六神丸后对于健康人上呼吸道菌群构成比和优势菌群占比,血液和肠道代谢产物的改变及可能作用机制。
|
Objectives of Study:
|
To investigate the composition ratio of upper respiratory tract microflora and the proportion of dominant microflora, the changes of intestinal and blood metabolites and the possible mechanism of action after oral administration and containing liushenwan.

药物成份或治疗方案详述:
|
本试验采用随机、空白对照、单盲、单中心研究方法。随机纳入健康受试者90人,随机分成对照组、六神丸口服组、六神口服+含服组。对照组不进行药物干预;六神丸口服组给予六神胶囊口服治疗7天,一日3次,一次1粒,六神胶囊为胶囊外衣包裹的六神丸制成,药物有效成分含量与六神丸相同;六神丸口服+含服组给予六神丸治疗7天,一日3次,一次含服3粒+口服7粒六神丸。并分别在试验前一天和第8天采集咽拭子、粪便和血液。采用宏基因技术,观察口服/含服六神丸对于健康人上呼吸道微生态优势菌丰度的调节。应用粪便和血液代谢组学研究方法寻找与六神丸作用人体后相关的潜在生物标志物。

Description for medicine or protocol of treatment in detail:
|
Randomized, blank control, single - blind, single - center study was used.90 healthy subjects were randomly included and divided into control group, liushenwan oral group and liushenwan oral-buccal group.The control group received no drug intervention.The liushenwan oral group was given liushen capsule oral treatment for 7 days, 3 times a day, 1 pill at a time.Liushenwan oral-buccal group was given liushenwan for 7 days, 3 times a day,7 pills orally and 3 pills melt in the mouth.Throat swabs and faeces were collected on day 1 and day 8, respectively.The effects of oral and sublingual administration of liushenwan on the abundance of microecologically dominant bacteria in the upper respiratory tract in healthy people were observed by using 16S rRNA high-throughput sequencing technology.Potential biomarkers related to the action of liushenwan on human body were searched by fecal and blood metabolomics.
