The objective of this study was to investigate the change of mean blood flux in Hegu acupoint after contralateral Hegu acupoint was stimulated.
Healthy volunteers (N=140) were placed in a temperature-controlled room as a resting state for 60 minutes. Then the measurements of skin blood flow were carried out in pre- and postacupuncture stimulation every 30 minutes over a total of 180 minutes using a Moor full-field laser perfusion imager. The change ratio of mean blood flux in Hegu acupoint was used to evaluate the contralateral stimulation effect in different groups.
After acupuncture of the right Hegu acupoint (AR), the change ratio of mean blood flux in the left Hegu acupoint was increased significantly compared with the control group 60 minutes after acupuncture stimulation (p<0.01). Then the blood flow in the AR group was sustained at a higher level compared with that of the control group (p<0.05). However, the change ratio of mean blood flux in the right Hegu acupoint increased significantly in the 30 minutes after contralateral acupuncture stimulation (p<0.01). From that point on, the change ratio was sustained at a higher level in the AR group than in the control group until 150 minutes after stimulation (p<0.05).
On stimulation of either the left or right side of Hegu acupoint, the change ratio of mean blood flux was increased in the contralateral Hegu acupoint in a period from 30, 60, to 150 minutes after stimulation, respectively.
本研究旨在探讨对侧合谷穴刺激后合谷穴平均血流的变化。
将 140 名健康志愿者置于温度受控的房间中作为休息状态 60 分钟。然后，使用 Moor 全视野激光灌注成像仪，在总共 180 分钟内，每 30 分钟进行一次针刺前和针刺后的皮肤血流测量。使用合谷穴平均血流的变化率来评估不同组的对侧刺激效应。
右侧合谷穴针刺（AR）后，与针刺刺激 60 分钟后对照组相比，左侧合谷穴平均血流的变化率明显增加（p<0.01）。然后，与对照组相比，AR 组的血流持续处于较高水平（p<0.05）。然而，对侧针刺刺激后 30 分钟，右侧合谷穴的平均血流变化率明显增加（p<0.01）。从那时起，AR 组的变化率在刺激后 150 分钟内持续高于对照组（p<0.05）。
无论是刺激左侧还是右侧合谷穴，在刺激后 30、60 和 150 分钟时，对侧合谷穴的平均血流变化率均会增加。
