Correlation between acupoints and zang-fu organs based on clinical trials.
A systematic analysis was made on the correlation between acupoints and pathological changes of the zang-fu organs through reviewing of literatures in the database of CNKI from 1959–2011 and the database of Pubmed of the past 10 years. The result showed that specificity was found on the pathological changes of zang-fu organs when acupoints were stimulated. And the pathological changes of the internal organs can be perceived from acupoints on the correspondent meridians, mainly regarding the heart, the stomach, the intestines, the lung and the liver, etc. And most of the researches focused on the correlation between acupoints of the heat meridian and the heart. It was also discovered that a lot of acupoints on various meridians could manifest the pathological changes of the same organ. Different effects of the same acupoints on different times could be found on the same internal organ. Therefore, it is concluded that there is a relative specificity between acupoints and pathological changes of the zang-fu organs. However, it is worth to study the regularity of specificity further.
