简要总结
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. Participants of chronic stable angina pectoris (CSAP) and healthy volunteers will be enrolled.
120 participants will be included and divided into the healthy control group, chronic stable angina pectoris (CSAP) 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 CSAP 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.
