[Role of "qi" in reaching affected area using acupuncture in "promoting blood circulation to remove blood stasis"]

In the present work, an experimental observation was carried out with the determination method of bioelectric impedance in 78 cases of chronic hepatitis, 58 cases of chronic obstructive pulmonary disease, 45 of obstructive thromboendarteritis and 65 of coronary heart disease, who were diagnosed definitely and possessed the symptoms and signs of blood stasis and produced change in hemodynamics. Yanglingquan (G. B. 34) and Zhangmen (Liv.13) acupoints on right side were needled and four indices of liver blood circulation were determined for chronic hepatitis. Bilateral Kongzui (Lu.6) acupoints were needled and seven indices of lung blood circulation were detected for chronic obstructive pulmonary disease. Acupoint along the pathway of channel were needled and six indices of blood circulation in the extremities were examined for obstructive thromboendarteritis. Bilateral Neiguan (P.6) acupoints were needled and four indices of the cardiovascular function were detected for coronary heart disease. Results showed 95 cases of the above four diseases having Qi reaching to affected area. 84 cases had propagated sensation along the channel. 67 cases had local sensation. Experimental results indicated that Qi reaching affected area produced obvious effects of dredging the meridian passage, and promoting blood circulation to remove blood stasis.
