目的观察正常生理状态下腹部常用穴穴区微循环的规律特点，比较不同温度艾灸对其微循环的影响差异。方法纳入52例正常青年志愿者（男18，女34），采用激光多普勒血流仪依次测量其腹部的神阙、肓俞、天枢、大横、水分、气海、关元、中脘穴穴区皮肤微循环值；随后从中选取神阙、天枢穴进行不同温度（40-43℃和〉43℃，〈44℃）艾灸干预，连续灸7次，每次2种温度各2min，观察不同温度艾灸对该两穴穴区皮肤微循环的影响。结果①正常生理状态下，神阙穴穴区微循环值明显高于其他所测穴位穴区的微循环值（P〈0．01）；肓俞穴微循环值高于天枢穴（P〈O．05）、大横穴（P〈O．01）；天枢穴微循环值高于大横穴（P〈O．01）。②艾灸后神阙、天枢穴微循环值均升高且神阙穴在2种温度艾灸时的微循环均值、最大值、与艾灸前的差值皆大于天枢穴（P〈O．01）；在艾灸刺激下，神阙穴微循环值较天枢穴先出现变化并且晚进入平台期；神阙穴微循环值对艾灸温度变化的反应比天枢穴敏感。结论腹部常用穴位中，神阙穴穴区的皮肤微循环值最高；腹部水平平脐的穴位整体表现出越接近脐，其皮肤微循环值越高的趋势。同等温灸条件下神阙穴穴区皮肤微循环值的升高速度、幅度和持续升高时间都优于天枢穴。初步明确神阙穴在腹部常用穴位中具有微循环的特殊性与优越性，为穴位微循环结构特异性提供有效的证据支撑。

OBJECTIVE To observe the rules and characteristics of microcirculatory blood perfusion at commonly-used ab- dominal points area under normal physiological conditions, and compare the effect of moxibustion at different temperatures on microcirculation. METHODS 52 health young volunteers were included （male, 18 cases; female, 34 cases）. Laser Doppler flowmetry was applied to measure the skin microcirculation values of their abdominal points including Shenque （CVS）, Huang- shu （KI16）, Tianshu （ST25）, Daheng （SP15）, Shuifen （CV9）, Qihai （CV6）, Guanyuan （CV4） and ZhongWan （CV12）. Then, Shenque （CV8） and Tianshu （ST25） were selected and intervened by moxibustion at different temperatures （40-43℃ and 〉43 ℃, 〈44 ℃）, and the moxibustion ~vas performed 7 times continuously, at 2 kinds of temperatures for 2 min each time. Effects of moxibustion at different temperatures on kin microcirculation of these two points were observed. RESULTS OUnder normal physiological conditions, microcirculation value of Shenque point （CV8） was obviously higher than that of oth- er points （P〈0.01）. Microcirculation value of Huangshu point （KI16） was higher than that of Tianshu point （ST25） and Da- I heng point （SP15）. Microcirculation value oflTianshu point （ST25） was higher than that of Daheng point （SP15）. ②After moxibustion, both microcirculation values of Shenque point （CVS） and Tianshu point （ST25） increased, and both the differ- mean and maximum microcirculation values of Shenque point （CV8） were higher than that of pre-moxibustion at two of ences temperatures. Under the stimulation of moxibustion, microcirculation value of Shenque point （CV8） changed earlier and reached platform later compared with Tianshu point （ST25）. The response of microcirculation value of Shenque point （CV8） was more sensitive to temperature changes than Tianshu point （ST25）. CONCLUSION Among commonly-used abdominal points, skin microcirculation
