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. 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 meridian phenomenon are urgently needed. Therefore, this study is designed to assess the heat transport characteristics of meridian phenomenon for the Heart and Lung meridians by using infrared thermal imaging. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.

Outcome Measures

Primary Outcomes (2)

  • Infrared thermal images

    Infrared thermal images could reflect the heat transport characteristics of meridian phenomenon.

    5 minutes

  • Acupoint temperature

    Acupoint temperature could reflect the heat transport characteristics of meridian phenomenon.

    5 minutes

Study Arms (2)

CSAP group

This group will include 40 patients with chronic stable angina pectoris (CSAP).

Device: Infrared thermal imaging

Healthy group

This group will include 40 healthy volunteers.

Device: Infrared thermal imaging

Interventions

Infrared thermal imaging will be adopted to assess the heat transport characteristics of meridian phenomenon for participants in the two groups. 1. Experimental device: a NEC InfRec R450 infrared thermal imaging camera 2. Experimental process: The participants will be allowed to stabilize for 15 minutes in a supine position in the experimental room before formal examination They are asked to keep silent, breathe normally and avoid movement of limbs during the whole measuring period. The height and angle of the infrared thermal imaging camera is adjusted so that the measurement sites of the participant's arm is located in the center of the camera screen. The infrared thermal imaging and acupoint temperature will be recorded for 5 minutes. 3. Measurement sites: Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan(LU9) and Chize (LU5) of the Lung meridian.
