Acupoint was reaction of viscera and its optical parameter was an important characteristic of tissue. In the present work, in order to discuss specificity of acupuncture on the response of qi and blood in human body, we compared the diffuse reflectance of Taichong (LV3), Taibai (SP3), and Chongyang (ST42) before, during and after menstruation. All the acupoints had the same shape of the spectrum and troughs were all at 423.16, 544.06 and 577.47 nm. The values of reflectance during menstruation were greater than before and after menstruation, especially for SP3 and ST42 (P < 0.05). SP3 and ST42 were more sensitive to the changes of qi and blood than LV3, and it was asymmetric and we found no evidence for the imbalance of the left side and right. These results indicated that acupoint diffuse reflectance changed with qi and blood, and that SP3 and ST42 had close relationship with menstruation. Diffuse reflectance may be possibly used in the quantitative analysis of qi and blood.
穴位是脏腑的反应点，其光学参数是组织的重要特征。在本研究中，为探讨针刺对人体气血反应的特异性，我们比较了太冲（LV3）、太白（SP3）和冲阳（ST42）在月经前、月经期间和月经后的漫反射率。所有穴位的光谱形状相同，波谷均位于423.16、544.06和577.47nm处。月经期间的反射率值大于月经前和月经后，尤其是SP3和ST42（P<0.05）。SP3和ST42对气血变化比LV3更敏感，且不对称，未发现左右失衡的证据。这些结果表明穴位漫反射率随气血变化，且SP3和ST42与月经密切相关。漫反射率可能可用于气血的定量分析。
