Two Definitions of Life Will Highlight on Physiological Understanding of Six Meridians

Treatise on Cold Pathogenic Diseases is an ancient guideline for traditional Chinese medicine(TCM) clinicians which classified all diseases into six meridians.In Treatise on Cold Pathogenic Diseases, many syndromes are enunciated in simple vocabularies without physiology and pathology, which is always criticized.It seems that a bridge is necessary for physiological and pathological understanding on Treatise on Cold Pathogenic Diseases.In past decade, two definition of life in cell and in our body are presented respectively.In both definitions, energy conversion is the core pathways for all organisms which can be regarded as motion of qi.Moreover, metabolism of energy agents can be seen as yang while gene expression and stem cell proliferation & differentiation(SCPD) should be seen as yin in cell and in our body respectively.The both definitions also outline the physiology and pathology of six meridians in Treatise on Cold Pathogenic Diseases, which can be unveiled as followings: taiyang meridian-elimination of energy and end metabolites;yangming meridian-acquiring energy agents;shaoyin meridian-the conversions of energy agents;taiyin meridian-new born somatic cell attending the metabolism of energy agents and then going to die;shaoyin meridian-storage and activity of stem cell;jueyin meridian-proliferation & differentiation of stem cell to produce somatic cell.These definitions will ignite new physiological and pathological understandings on Treatise on Cold Pathogenic Diseases.
