Abstract

This study is to investigate the correlations among Sanjian (LI3), Hegu (LI4), and Yangxi (LI5) acupoints and their corresponding nonacupoints on the Yangming Large Intestine Meridian of Hand before and after laser irradiation using optical coherence tomography (OCT) and diffuse reflectance spectra. The experiment was conducted on 10 healthy people. A 658 nm laser with 50 mW output power was used for irradiating LI4, LI5 acupoints and their corresponding nonacupoints. As to LI4 acupoint with laser irradiation for duration of 15 or 45 minutes, the OCT backscattered light intensities of LI4 and LI5 acupoints increased significantly, and the reflectance intensities (RIs) of the LI3, LI4, and LI5 acupoints decreased significantly. As to LI5 acupoint with laser irradiation for duration of 15 or 45 minutes, the changes of OCT backscattered light intensities of the corresponding irradiated acupoint and LI4 acupoint increased significantly, and the RIs decreased significantly. However, the OCT backscattered light intensities and RIs for their nonacupoints were almost not changed. The results show that an association exists between two adjacent same-meridian acupoints on the same meridian after laser-needle acupuncture to some extent.

摘要

本研究旨在运用光学相干断层扫描（OCT）和漫反射光谱技术，探究激光照射前后手阳明大肠经三间（LI3）、合谷（LI4）、阳溪（LI5）穴位及其相应非穴位之间的相关性。实验选取10名健康受试者进行。采用输出功率为50 mW的658 nm激光，对LI4、LI5穴位及其相应非穴位进行照射。对于照射时长为15分钟或45分钟的LI4穴位，LI4和LI5穴位的OCT背向散射光强度显著增加，而LI3、LI4和LI5穴位的反射率强度（RIs）显著降低。对于照射时长为15分钟或45分钟的LI5穴位，相应照射穴位和LI4穴位的OCT背向散射光强度变化显著增加，RIs显著降低。然而，其非穴位的OCT背向散射光强度和RIs几乎未发生变化。结果表明，激光针刺后同一经络上两个相邻的同经络穴位之间在一定程度上存在关联。
