基于光谱法的中医证型快速诊断

Rapid Diagnosis of TCM Syndrome Based on Spectrometry

传统中医的诊断中对舌色的观察是信息来源的重要方面,但中医望诊中,肉眼的判断会受到环境变化和医生主观的影响,对症候的诊断会产生一定的误差。作者从光谱学的角度入手,提出一种全新的中医客观化方法,用连续的光谱信息替代单一舌色,进而研究舌部携带信息的本质。实验中使用近红外光谱,对53个表寒里热患者、37个健康人和21个风寒患者采集舌部的反射光光谱信息,通过matlab进行数据预处理,利用minitab进行偏最小二乘法的建模和预测,可将健康人和表寒里热患者区分开,准确率达到85.6%,但近红外光谱的舌诊数据并不能区分表寒里热和风寒患者。文章为中医舌诊的客观化提供了一种全新的方法,为更深入地研究中医证候提供了数据支持。

Tongue color provides important information in traditional Chinese medicine（TCM） diagnosis,but in the process of TCM inspection,the various surrounding environment and subjective effect of doctors will influence the correctness of diagnosis.The present article put forward a brand new thought to study TCM objectivity,that is to research the essence message of tongue from perspective of spectrum,study the continuous spectrum to replace the observation of tongue color.The experiment used near infrared spectrum to collect reflection spectrum data of tongue among 53 exterior cold and interior heat patients,37 healthy people and 21 wind chill suffers.Used matlab for data pretreatment,minitab for statistics modeling and prediction used partial least squares,the accuracy of prediction is 85.6%,but however,the spectrum of near infrared fail to distinguish exterior cold and interior heat patients from wind chill sufferers.The article provides a brand new way to implement the objectivity of tongue diagnosis in TCM,and also offers data support for the study of TCM syndrome.
