Clinical Trial 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. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridians are urgently needed. Therefore, this study is designed to assess the metabolic characteristics of the Heart and Lung meridians by using functional near infrared spectroscopy. Thus, the biological characteristics of meridians could be presented objectively in a scientific methodology.


Description:

The Lung and Heart meridians are chosen as two specific studied meridians. Participants of chronic obstructive pulmonary disease (COPD) and healthy volunteers will be enrolled.

120 participants will be included and divided into the healthy control group, chronic obstructive pulmonary disease (COPD) group and healthy intervention group. Functional near infrared spectroscopy will be used to assess the metabolic characteristics of the Heart and Lung meridians. The specificity for the meridian-visceral association will be investigated by comparing the metabolic 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 specificity for the site-to-site association.

Study Design


Related Conditions & MeSH terms


Intervention

Device:
Functional near infrared spectroscopy
Functional near infrared spectroscopy will be adopted to assess the metabolic characteristics of the Heart and Lung meridians. The probes will be left at 4 measurement sites, which include Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan (LU9) and Chize (LU5) of the Lung meridian.
Procedure:
Moxibustion
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 near infrared spectroscopy will detect the metabolic characteristics of three measuring sites, which include the midpoint of the Heart meridian along the forearm, Chize (LU5) of the Lung meridian, and the midpoint of the Lung meridian along the forearm. Intervention in the Lung meridian: moxibustion will be performed above Chize (LU5) for 15 minutes. During moxibustion, the probes of near infrared spectroscopy will detect the metabolic 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 forearm.
