Objective:To observe the effect of local skin temperature and the remote skin temperature on PC8 acupoint under two different irradiations of synchronous pulse beam (the stimulus frequency was associated with the pulse of figure provided by biologi-cal information feedback infrared therapeutic apparatus)and continuous illumination on surface microcirculation (finger pulse), and to discuss whether the energy utilization of synchronous pulse radiation on surface microcirculation (finger pulse)is better than the continuous illumination.Methods:A total of 60 patients were randomly divided into two groups:synchronous pulse group and continuous irradiation group,30 patients in each group,and then we observed the effects of different exposure modes on skin tem-perature,finger pulse microcirculation,and heart rate at 1 minute intervals for local (peripheral umbilicus and right elbow)and distal right palm (PC8).Results:The skin temperature and palmar skin temperature of the two groups rose significantly (P <0.01),but the temperature of local skin in the synchronized pulse group was (3.53 ±1.39)℃,which was significantly lower than that in the continuous irradiation group (4.62 ±1.38)℃,P <0.01).After 15 minutes of irradiation the skin temperature of the right hand palm (PC8)was (1.45 ±1.07)℃,which was higher than that of the continuous irradiation group (1.08 ± 1.00)℃,but there was no significant difference (P >0.05).Elbow irradiation result was similar to periumbilical irradiation re-sult.Conclusion:By contrast,surface skin microcirculation (finger pulse)synchronous pulsation of the local skin temperature is lower,that it created the conditions to achieve “adequate moxibustion amount”.The skin temperature was higher at the distal palm,and that can promote the human body microcirculation.The experimental results show that the synchrotron pulsed irradiation method of bioinformation feedback infrared therapeutic apparatus is superior to the continuous irradiation method.%目的：采用生物信息反馈红外治疗仪，观察指尖微动脉搏动节律同步脉动照射和连续照射两种不同照射方式对局部皮肤温度和远端劳宫穴皮肤温度的影响，探讨随指尖微动脉搏动节律行同步脉动照射方式是否优于连续照射方式。方法：将纳入照射研究的60人次随机分为2组：同步脉动组、连续照射组，每组30人次，观察不同照射方式对局部脐周和右手肘关节及远端右手劳宫穴每隔1 min 的皮肤温度、指脉微循环脉图高度、心率的情况。结果：脐周照射同步脉动组与连续照射组照射前、后局部皮肤温度和右手劳宫穴皮肤温度均显著升高（P ＜0．01），但照射前后局部皮肤温度升高同步脉动组为（3．53±1．39）℃，显著低于连续照射组的（4．62±1．38）℃（P ＜0．01）。15 min 照射前、后右手劳宫穴皮肤温度升高同步脉动组为（1．45±1．07）℃，高于连续照射组的（1．08±1．00）℃，但差异无统计学意义（P ＞0．05）。肘关节照射后结果与脐周照射相似。结论：体表微循环指脉同步脉动照射与连续照射相比，体表微循环指脉同步脉动照射的局部皮肤温度较低，为实现充足灸量创造了条件，远端劳宫穴皮肤温度较高，更能促进人体远端微循环。说明生物信息反馈红外治疗仪大力神雀啄灸的同步脉动照射方式比连续照射方式的在能量利用方面更有优势。
