简要总结
Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. The majority of the existing studies involve lots of subjective assessments for meridian phenomena. In addition, few studies have investigated the site specificity between two specific meridians.Therefore, this study is designed to detect the microcirculatory characteristics of meridian phenomena by using an objective assessment tool and investigate the site specificity for the meridian-visceral association and surface-surface association between two specific meridians.
详细描述
The Lung and Heart meridians are chosen as two specific studied meridians. 120 participants will be enrolled and divided into the healthy control group, chronic obstructive pulmonary disease (COPD) group and healthy intervention group. Laser doppler flowmetry (LDF) will be used to assess the microcirculatory characteristics of meridian phenomena for the Heart and Lung meridians. The site specificity for the meridian-visceral association will be investigated by comparing the microcirculatory difference between the Heart and Lung meridians in the healthy control group and COPD group. Besides, participants in the healthy intervention group will receive two sessions of moxibustion in the Heart meridian and Lung meridian respectively to explore the site specificity for the surface-surface association.
