有关得气的误解：从历史回顾到实验研究

对得气与针感的历史进行了溯源，探讨了酸麻胀痛重等作为得气代名词的误解过程，并探讨与介绍了得气的现代意义与实验室研究。虽然海内外对针刺后的酸麻胀痛重感与疗效的关系一再提出争议，但实际上这是一种以针感代得气的误解，有些针刺可能并无酸麻胀痛重感，但同样使受刺者产生舒适感，同时刺者手下可能也有感觉，这其实已经属于得气状态，而这种状态通过实验室的研究可望通过功能性核磁共振等手段进行检测，从而使得气或针感可以有指标可循。

Some misunderstandings of deqi phenomenon: from historic review to experimental study

In this paper, the authors trace back to the historic source of deqi and needling sensation, and probe the misunderstanding course of the feeling of sourness, numbness, distension, aching or heaviness used as synonym of deqi, and explore and introduce the modern significance and experimental studies of deqi. Although there are arguments in relationship between the feeling of sourness, numbness, distension, aching or heaviness after acupuncture and effect of acupuncture at home and abroad, in fact, this is a misunderstanding of needling sensation replacing deqi. Sometimes acupuncture possibly does not induce sourness, numbness, distension, aching or heaviness, but it also induces patient's comfortable sensation and at the same time acupuncture practitioners possibly have a sensation under the hand, which is at the state of deqi. The two states will be detected by fMRI in experimental studies, so as to have indexes to be followed for deqi or needling sensation.
