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

OTHER

Participants 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.

Device: Laser doppler flowmetry

Healthy control group

OTHER

Participants 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.

Device: Laser doppler flowmetry

Healthy intervention group

EXPERIMENTAL

Participants in the healthy intervention group will receive intervention of moxibustion in the Heart and Lung meridians.

Other: MoxibustionDevice: Laser doppler flowmetry

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.

Healthy intervention group

Laser doppler flowmetry will be used to detect the microcirculatory characteristics of meridian phenomena for the Heart meridian and Lung meridians.
