[Interior-exterior relation of meridians under two meridian modes].

The connotation and core meaning of interior-exterior relation of meridians were studied and analyzed on the base of two meridian modes, namely the original meridian model and the zang-fu-meridian model. And it was concluded that different features and meanings can be found under the above two models. 1) Original meridian model: six-coincidence theory in Lingshu: Jingbie (Miraculous Pivot: Divergent Meridian) is the core of interior-exterior relation of meridians; collaterals (connecting point) play a very important role in communicating the interior-exterior relation of meridians. 2) Zang-fu-meridian model: zang-fu organ coincidence can promote the matching and communication of meridians with interior-exterior close relationship; circulation of qi and blood has a positive impact on interiorly and exteriorly related meridians.
