“以常衡变”诊断原理及其在中医学的应用

Diagnosis theory of ‘using constant to measure variation’ and its application in traditional Chinese medicine

中医思维原理与中国古代哲学一脉相承,其在中医临床实践中起着关键的作用。文章通过梳理“常”与“变”的哲学本原和辩证关系,明析“以常衡变”诊断原理,继而提出以“顺、逆”和“有余,不足”作为权衡变化的尺度,从自然之常道、生命之常态角度分析如何运用“以常衡变”揆度机体生理和异常改变的应用。希冀深化和传承“以常衡变”的意蕴,充分发掘其理论价值及中医临床诊断意义。

Traditional Chinese medicine(TCM) thinking is in line with ancient Chinese philosophy, which plays a key role in TCM clinical practice. By combing the philosophical origin and dialectical relationship between constant and variation,this paper clarified the diagnosis theory of ‘using constant to measure variation’ thinking. Then adaptation-inverse and surplusdeficiency were proposed to weigh change as a rule, so as to analyze how to use the thinking of ‘using constant to measure variation’ thinking to understand the abnormal changes of body physiology and disease pathology from the perspective of normal nature and normal life. By this way, we hope to deepen, inherit the implication of ‘using constant to measure variation’ and fully explore its theoretical value and TCM clinical diagnostic significance.
