不同健康状态的面部光谱色度特征分析

Analysis of Different Health Status Based on Characteristics of the Facial Spectrum Photometric Color

以《内经》面色诊理论为指导,运用光谱色度测定方法,观察不同健康状态人群面部面色光谱色度情况。本研究采用日产柯尼卡美能达CM-2600D分光测色仪,观测健康组(183例)、亚健康组(287例)以及疾病组(370例)额部、眉间部、鼻部、下颏、左颧部、右颧部、左眼胞及右眼胞8处L、a、b、C值及不同波长段(400～700nm)下的面色反射率值等指标情况。结果显示亚健康L值高于其他两组,a、b、C值均低于其他两组;疾病组L值低于其他两组,b、C值均高于其他两组;各组间不同波长段下反射率与上述色度结果基本一致,惟在400～570nm波长段亚健康状态组的反射率明显高于健康状态组(P<0.05)。提示疾病组晦暗深重的面色特征,亚健康组面部浅淡的特点。各组的6个位点间的L、a、b、C值均具有不同程度的显著性差异(P<0.05),且各个组别均在面部中央位置的差异最为显著。三组面部同一点位间颜色信息进行比较,得到各组别较其他组别具诊断特异性的点位。运用光谱色度测定方法,可以作为诊断亚健康和疾病状态的重要指标。为中医望色诊断提供了较好的量化依据。

Abstract： This paper is aimed to observe the difference of facial color oi people with dillerent health status by spectral photometric color measuring technique according to the theory of facial color diagnosis in Internal Classic. We gathered the facial color information about the health status of persons in healthy group （183）, sub-healthy group （287） and disease group （370） respectively. The information included L, a ,b, C values and reflection of different wavelengths in 400-700nm with CM-2600D spectral photometric color measuring instrument on 8 points. The results indicated that overall complexion color values of the people in the three groups were significantly different. The persons in the disease group looked deep dark in features. The people in the subealthy group looked pale in features. The loci L, a, b, C values were with varying degrees of significant differences （P〈0. 05） at 6 points among the groups, and the central position of the face in all the groups was the position with most significant differences. Comparing the facial color information at the same point of the people in the three groups, we obtained each group＇s diagnostic special point. There existed diagnostic values in distinguishing disease status and various status of health in some degree by spectral photometric color measuring technique. The present method provides a prosperous quantitative basis for Chinese medical inspection of the complexion diagnosis.
