[Intermediate structure of the interior-exterior relationship between lung and large intestine].

Through analysis and study of ancient literatures, it is primarily approved that there existed a connective subject, namely intermediate structure, between the "lung-lung meridian" and the "large intestine-large intestine meridian", which can promote the interior-exterior close relationship between the two. It mainly includes intermediate of the organism (throat, supraclavicular fossa, the bone formed elbow joint, nose, anus and skin), intermediate of acupoints (Luo-connecting points) and intermediate of zang-fu, meridians and collaterals (stomach and the Stomach Meridian of Foot-Yangming, liver and Liver Meridian of Foot-Jueyin). The theory provides new thoughts for study on the interior-exterior relationship between the corresponding zang and fu organs.
