论《黄帝内经》之“上下病机”

On the “Upper and Lower Pathogenic Mechanisms” in the Huangdi Neijing

摘要: 病机十九条出自《黄帝内经》一书，是关于中医理论的重点条文，该段条文揭示了疾病的病因、病位、病症等之间的关系，具体包含五脏病机、上下病机、六淫病机。在这三者之中，上下病机仅有两句，言简意深，有诸多值得思考与探讨之处。站在巨人的肩上，本文根据他人对上下病机的不同解释，来表达一些新的认识。

Abstract: The Nineteen Pathogenetic Principles originates from Huangdi Neijing, and constitutes a key set of clauses in traditional Chinese medicine (TCM) theory. This set of clauses reveals the correlations among the etiology, location and manifestations of diseases, and specifically covers pathogeneses of the five zang-organs, pathogeneses of the upper and lower body regions, and pathogeneses of the six climatic exopathogens. Among the three categories, the pathogenesis of the upper and lower body regions is covered in only two sentences, which feature concise wording with profound implications, and contain many contents worthy of in-depth reflection and discussion. Building on previous academic achievements, this paper proposes novel insights based on a review of existing different interpretations of the upper and lower pathogeneses.
