Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
Change from baseline blood flow curve
Laser doppler flowmetry is used to assess blood flow curve of relevant sites along the Heart and Lung meridians
5-minute baseline, 15 minutes during moxibustion and 5 minutes after stopping moxibustion
Change from baseline blood perfusion units
Laser doppler flowmetry is used to assess blood perfusion units of relevant sites along the Heart and Lung meridians
5-minute baseline, 15 minutes during moxibustion and 5 minutes after stopping moxibustion
Study Arms (3)
COPD group
OTHERParticipants in the COPD group will receive examination of laser doppler flowmetry(LDF). The LDF probes will be left at 4 measuring acupoints, which include Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan (LU9) and Chize (LU5) of the Lung meridian.
Healthy control group
OTHERParticipants in the healthy control group will receive examination of laser doppler flowmetry(LDF). The LDF probes will be left at 4 measuring acupoints, which include Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan (LU9) and Chize (LU5) of the Lung meridian.
Healthy intervention group
EXPERIMENTALParticipants in the healthy intervention group will receive intervention of moxibustion in the Heart and Lung meridians.
Interventions
Two sessions of moxibustion will be performed in the Heart meridian and Lung meridian successively. Intervention in the Heart meridian: moxibustion will be performed above Shaohai (HT3) for 15 minutes. During moxibustion, the probes of laser doppler flowmetry will detect the microcirculatory characteristics of three measuring sites, which include the midpoint of the Heart meridian along the left forearm, Chize (LU5) of the Lung meridian, and the midpoint of the Lung meridian along the left forearm. Intervention in the Lung meridian: moxibustion will be performed above Chize (LU5) for 15 minutes. During moxibustion, the probes of laser doppler flowmetry will detect the microcirculatory characteristics of three measuring sites, which include the midpoint of the Lung meridian along the left forearm, Shaohai (HT3) of the Heart meridian, and the midpoint of the Heart meridian along the left forearm.
Laser doppler flowmetry will be used to detect the microcirculatory characteristics of meridian phenomena for the Heart meridian and Lung meridians.
