About this study

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 metabolic characteristics of meridian phenomenon for the Heart and Lung meridians by using near infrared spectroscopy. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.

Read the detailed description

This study will include 40 patients diagnosed with chronic stable angina pectoris (CSAP) and 40 healthy volunteers. Near infrared spectroscopy will be adopted to assess the metabolic characteristics of meridian phenomenon for Heart and Lung meridians in the physiology/pathological state. In addition, by comparing the metabolic characteristics in the acupoints along the Heart and Lung meridians, the relative specificity of the two meridians will also be investigated.

Primary outcomes will be regional oxygen saturation (rSO2). Furthermore, this study will build standardized techniques and schemes for detecting the metabolic characteristics of meridian phenomenon for Heart and Lung. The results of this study could also provide scientific foundation for traditional meridian theories.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Near infrared spectroscopyDevice

    Near infrared spectroscopy will be adopted to assess the microcirculatory characteristics of meridian phenomenon for participants in the two groups.

    1. Experimental device: a four-channel INVOS 5100C Oximeter (Somanetics Corp., Troy, USA)
    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. After ripping the transparent adhesive tape on the probe, the probes will be left at 4 measuring sites. Regional oxygen saturation (rSO2) 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.
