亚健康状态的面部光谱与五脏色色度特征

目的：观察健康人群和亚健康状态人群面部不同点位的光谱色度情况,为健康状态的评价提供客观依据。方法：用＂健康状态评价问卷＂H20V2009对470名无明确急慢性疾病者进行健康状态评估,根据主观量表得分分为健康状态、亚健康状态,并根据中医辨证对亚健康进行五脏定位分析。采用CM-2600D分光测色仪,观测额部、眉间部、鼻部、下颏、左颧部、右颧部、左眼胞及右眼胞8处的L、a、b、C值以及400～700nm不同波长段的面色反射率。结果：与健康组比较,亚健康组整体面部色度特征L值偏高（P〈0.05）,a、b、C值偏低（P〈0.05）,提示亚健康组面色较健康组浅淡、色度偏低;在400～560nm段波长反射率,亚健康组偏高（P〈0.05）,显示亚健康组面色偏青;亚健康组面部额部、眉间、鼻部a、b和C值差异明显。亚健康五脏分型各组L值较健康组升高（P〈0.05）;亚健康不同脏腑辨证组间色度值存在一定差异,其中肺型与其他各型差异最显著,a、b和C值较其他各型降低;亚健康不同脏腑辨证组间光谱反射率比较,肺型在400～520nm、脾型在420～600nm段与其他各组差异有统计学意义（P〈0.05）,肺型低于其他脏型,脾型高于其他脏型。结论：亚健康状态不同五脏辨证分型者的面部不同点位光谱色度不同,可以为健康的评价提供客观依据。

Facial spectrum and color characteristics of five viscera reflecting on the face in sub-health status

OBJECTIVE： To observe the facial spectrum and color of different points, the positions of heart, liver, spleen, lung and kidney of traditional Chinese medicine reflecting on the face, in healthy participants and those with a sub-health status, so as to provide an objective basis for health evaluation. METHODS： The health condition of 470 subjects without acute and chronic conditions was assessed using the Health Evaluating Questionnaire H20 V2009. The subjects were diagnosed with health （more than 80 score） or sub-health （score between 60 and 80） status according to the questionnaire score. The subjects with a sub-health status were also analyzed using the five-viscera syndrome differentiation of traditional Chinese medicine using the form for collecting information according to the four examinations. Then for gathering the facial color information, CIE L＊a＊b and C values and reflections of wavelengths ranged from 400 to 700 nm were measured using a CM-2600D spectrophotometer on 8 points of the face, including the frontal part, glabellas, nose, mandible, two cheeks and eyelids. RESULTS： L value of the sub-health group was higher than that of the health group （P〈0.05）, and a, b and C values were lower than those of the health group （P〈0.05）, suggesting that the facial complexion of the sub-health group was pale/whiter than the health group. The reflectance rates of wavelengths （from 400 to 550 nm） of the sub-health group were higher than those of the health group （P〈0.05）, which suggested that the facial complexion of the sub-health group was partially green. The a, b and C values of the forehead, glabellas and nose of subjects in the sub-health group were apparently different from the health subjects. L values of five-viscera types were significantly different from people of a health status （P〈0.05）. There were some differences in color values among the five-viscera groups： lung group’s color values were significantly different from the others in terms of a, b and C values. The spectral reflectance of different viscera groups of the sub-health group also showed certain differences： reflectance of wavelengths at 400 to 490 nm in the lung group and at 520 to 580 nm in the spleen group showed significant difference from the other groups, and the lung group was lower and the spleen group was higher than the others. CONCLUSION： There are some differences in facial spectrum and color in different sites of the face in sub-health status of different viscera syndrome types, which can provide an objective basis for health evaluation.
