目的：探讨腧穴热敏态红外客观显示的可能性。方法：共纳入心气虚患者74例。在自然状态下采用热断层扫描成像系统（TTM）拍摄双前臂内侧红外热像图，图像采集完毕，接受灸感法热敏检测（艾条悬灸内关穴10min）。悬灸结束后记录患者内关穴产生扩热、透热的例数，然后再进行第2次红外辐射测量，记录艾灸后前臂内侧红外图像变化，比较两种检测法对心气虚患者内关穴热敏态的检测差异。结果：艾灸前患者内关穴区红外辐射强度多数显示高温特征，与患者灸感比较，其敏感性为66．7％，特异性为76．9％，准确性为70．3％。艾灸内关穴区后，发生热敏化的内关穴区产生明显的沿前臂内侧纵向扩散的红外辐射增强区域，与患者灸感比较，其敏感性为87．5％，特异性为92．3％，准确性为89．2％。结论：（1）心气虚患者内关穴区热敏态在一定程度上可被红外成像客观显示。（2）艾灸热敏腧穴产生的腧穴扩热、传热的热敏现象，受试者的主观感觉与红外成像有明显的相关。

英文摘要：

Objective To compare the method of detecting heat-sensitive （HS） condition of Neiguan（PC 6）with moxibustion sensation and with infrared in heart-qi deficiency patients（HQD）, and to find an objective detection method for HS condition of acupoints. Methods The study was performed on 74 HQD patients. Take infrared thermograph of the tested skin area in natural state. Then thermosensitive test was taken after infrared thermograph acquisition（suspended moxibustion for 10 min）. After moxibustion infrared radiometry was implemented for the secend time. The infrared radiation information of the forearms was collected and the major axis of the moxibustion reaction area was recorded. The effect of moxibustion sensation and infrared detection on HS Neiguan （PC 6） in HQD patients was compared. Results When the Neiguan（PC 6） in HQD patients was on HS condition, most of the infrared intensity was high temperature and compared with moxibustion sensation method, the sensitivity was 66.7%, the specificity 76.9%, and the accuracy 70. 30%. After moxibustion on the HS Neiguan（PC 6） area,the infrared intensity diffused longitudinally along inner side of forearms. Compared with the result of the moxibustion sensation method, its sensitivity was 87.5 %, the specificity 92.3 %, and the accuracy 89.2 %. Conclusion （1） The state of HS condition of Neiguan （PC 6） in HQD patients could be detected objectively by infrared radiation. （2）After moxibustion, the HS condition of acupoints produced thermal phenomena as thermal expansion, heat transfer, which could be demonstated objectively by the infrared radiation image as well as the sensation of subjects.
