About

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.

Full 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.

Enrollment: 120 estimated patients

Sex: All

Ages: 35 to 75 years old

Volunteers: Accepts Healthy Volunteers
