摘要
目的:观察耳穴在月经前后人体气血盈亏变化过程中的反射光谱特征及其差异性,探讨耳穴反映人体气血变化的相对特异性。方法:采用线阵电荷耦合元件探测器的光纤光谱仪无损获取子宫(TF2)、肝(CO12)、内分泌(CO18)3个耳穴在月经前后不同时间的可见光反射光谱,并对特定波长处的反射率进行比较。结果:随着人体机体气血盛衰的变化,3个耳穴的漫反射光谱表现出规律性的变化,即月经期的漫反射率高于月经前和月经后,这种趋势以TF2最为显著;在血红蛋白吸收峰附近544.06 nm、555.17 nm及577.47 nm波长处,TF2在月经期的反射强度显著高于月经前及月经后(P<0.01);TF2反射强度变化的差值大于CO12及CO18,尤其以TF2月经期与月经后的差值显著高于CO12及CO18月经期与月经后的差值(P<0.05)。结论:耳穴漫反射光的变化与机体气血盛衰有关,其在反映机体气血盛衰方面存在相对特异性,子宫为反映胞宫气血变化最灵敏的耳穴。
OBJECTIVE： This study aimed to assess the specificity of auricular acupoints in responding to changes of qi and blood which, in traditional Chinese medicine, are considered as the fundamental substances in the human body for sustaining normal vital activity. METHODS： A miniature fiber optic system was used to invasively measure the diffuse reflectance spectra of three auricular acupoints, namely, Uterus （TF2）, Gan （CO12） and Neifenmi （CO18）, at different stages of menstruation, when the female body exhibits regular changes of qi and blood. The spectra of different acupoints were compared to find their difference in responding changes of qi and blood, especially the reflectivity of absorption peaks of hemoglobin. RESULTS： The reflectivity of the same auricular acupoint during menstruation is higher than that before and after menstruation, and this trend is more obvious for the Uterus point compared with the points Gan and Neifenmi. The average reflectivity of the Uterus point during menstruation was significantly higher than that before or after menstruation （P〈0.01）. The D-values during and after menstruation of the Uterus point were greater than those of the points Gan and Neifenmi at 544.06 and 577.47 nm, respectively （P〈0.05）. CONCLUSION： The diffuse reflectance light of auricular acupoints changes as qi and blood fluctuates, and there is relative specificity among different auricular acupoints in reflecting changes of qi and blood. The Uterus point may be the most sensitive auricular acupoint in reflecting uterus function and subsequent changes of qi and blood.
