A recent paper published in the international authoritative journal “Evidence-based Complementary and Alternative Medicine” shows that for the first time, researchers mainly from the Life Science Research Institute of ENN Group clearly observed the continuous migration of acupoints along the meridians of the human body. Fluorescent lines, this work provides a strong evidence to confirm the existence of TCM meridians. Scientists from the Chinese Academy of Chinese Medical Sciences and Harvard University Medical School participated in the collaboration and verification.
According to reports, an important basis for the Western medical community to deny TCM science is that it “cannot prove the existence of meridians” at the anatomical level. “In recent decades, many teams at home and abroad have done a lot of exploration through various methods, but they have not been able to observe stable meridian trajectories with sufficient length on the human body.” said Dr. Tang Qing, team leader of ENN This time, the team’s experiment obtained a clear fluorescence image of the meridian over 20cm in the arm of the pericardium meridian. This is the first time that researchers have used a new method of tracing to obtain the meridian trajectory in the human body since the radioisotope method was used for tracing in the 1980s. Tang Qing said that the meridian imaging is more stable this time, and the trajectory of multiple acupoints along a meridian is clearer and repetitive.
Tang Qing specifically introduced that the team initially used the contrast agent sodium fluorescein, and in the following hours, used laser to excite and take pictures of the sodium fluorescein to obtain the migration trajectory of the fluorescent agent in the body. The results show that the trajectory generally develops along the adjacent acupoints of the pericardial meridian, from Neiguan, Jianshi, to Quchi, which completely overlaps the acupoints of the pericardial meridian, forming a stable meridian line. By contrasting ultrasound imaging and infrared imaging, the possibility of fluorescent lines flowing along blood vessels is ruled out. In order to rule out the possibility that the trajectory of the fluorescent line is a lymphatic vessel, the researchers designed an experiment in which sodium fluorescein and indocyanine green, a contrast agent mainly used for lymphography, were injected simultaneously. The results showed that the two trajectories did not completely overlap, so It can be ruled out that the previously observed fluorescence lines of sodium fluorescein are lymphatic vessels.
Tang Qing said frankly that this time they have made some progress in the visualization of the meridians and laid the foundation for the follow-up work, but there is still a lot of work to be done to fully grasp the secrets of the meridians. It is understood that as of the publication of the paper, in addition to the pericardial meridian, the research team has used the same method to observe three fluorescent lines running along the other meridians. “In the next step, we will verify the biophysical characteristics of the meridian of the fluorescent line, including low flow resistance and low resistance, and carry out functional studies.” Tang Qing believes that these studies have important scientific value for the interpretation and development of the basic theories of Chinese medicine. .
