title: [On "Xueluo"].
abstract: The author has carried out a detailed survey on the concept of Xueluo in ancient medical literature. It is shown that the original meaning of Xueluo is collaterals and subcollaterals (blood vessels) occurring in body surface and having color and morphologic changes in the pathological condition. More of annotators of the Internal Classic understood Xueluo as Pibuluo or Fuluo, which implies that Xueluo has had a new kind of physiological and theoretical conceptualization. Some other physicians of past generations, such as WANG Hong-han, YE Tian-shi, and et al., made great complexity in understanding of Xueluo and their understanding were proposed on the basis of application of Xueluo. As far as the historical changes of Xueluo's concept is concerned, there is no more change in the original meaning of it's concept, while as the applying of it's concept is concerned, there are obviously changes of ductility in different dimension, so that abundant academic connotation of it's concept is manifested. It is suggested that clearing the connotation of Xueluo's concept and identifying the category of acu-moxibustion theory are of great significance to correctly understand and inherit acu-moxibustion theory.
