摘　　要：目的:观察正常人面部穴区血流灌注量,并分析针刺对该血流灌注量的调整作用。方法:使用激光多普勒血流成像仪采集30例健康人自然状态和针刺合谷穴30min前后面部血流图像,统计穴区血流灌注量,分析对称性以及针刺对面部左右侧穴区血流灌注量的影响。结果:正常人面部穴位血流灌注量大多都在0.73～1.17PU范围之间,以巨髎、口禾髎、四白、承泣等血流量较大,下关、牵正、丝竹空等穴血流量较小。自然状态30min前后,正常人面部血流灌注量无明显的升降变化,左右侧同名穴血流灌注量存在小幅差异。针刺30min后正常人面部穴区血流灌注量显著增加(P<0.05,P<0.01),其中左侧巨髎、左侧承泣、左侧丝竹空、左右侧夹承浆和右侧大迎血流灌注量的增加值与自然状态下的变化值相比,差异具有统计学意义(P<0.05,P<0.01)。结论:面部左右侧穴位血流灌注量存在较小差异,针刺可以增加面部双侧穴位血流灌注量。Objective To observe the blood perfusion levels in different facial acupoint regions and changes after acu- puncture stimulation of Hegu （L1 4）. Methods Thirty healthy volunteer subjects were equally divided into control group and acu- puncture group. Blood perfusion levels of different facial acupoint areas were detected using a Laser Doppler Imager. Acupuncture stimulation was applied to bilateral Hegu （L1 4） by using two filiform needles which were manipulated for a while till ＂Deqi＇, fol- lowed by keeping them in position for 30 min. The needles were then manipulated once again every 10 min. Results The blood perfusion levels of facial acupoint regions were from 0.73 to 1. 17 PU in healthy volunteers, with relatively higher levels being in Juliao （ST 3）, Kouheliao （L1 19）, Sibai （ST 2） and Chengqi （ST 1） regions and relatively lower levels in Xiaguan （ST 7）, Qianzheng （Ex-HN） and Sizhukong （TE 23） regions, but without significant difference between the isonym acupoint areas of the bi- lateral face in the control group. Following acupuncture stimulation of bilateral Hegu （L1 4）, the blood perfusion volumes were re- markably increased in the acupoint regions on bilateral sides of the face （P〈0.05, P〈0. 01）. Conclusion Acupuncture of Hegu （L1 4） can effectively increase blood perfusion volume of the acupoint areas of the bilateral face in healthy volunteers.
