艾灸百会穴对大脑后动脉血流速度的影响

目的:检测艾灸百会穴对健康人大脑后动脉(PCA)血流动力学的变化;方法:选择本校健康男性学员30名,年龄20～22岁之间,分别测试双侧大脑后动脉最大血流速度(Vmax)、最小血流速度(Vmin)、搏动指数(PI)、阻力指数(RI)等与血流动力学有关参数;结果:艾灸百会穴5天后,右侧大脑后动脉最大血流速度(Vmax)及搏动指数(PI)增加显著(P《0.01);左侧大脑后动脉最大血流速度(Vmax)及右侧大脑后动脉最小血流速度(Vmin)增加亦显著(P《0.05),其余各项指标虽有不同程度的变化,但无统计学意义.结论:艾灸百会穴可使大脑后动脉血流速度明显加快,血管阻力降低,脑血流量增加.本研究证实艾灸百会穴治疗脑血管病具有重要意义.

Influence of Moxibustion in Baihui (DU20) on the Hemodynamics of Bilateral Posterior Cerebral Artery

Aim: To study the effects of moxibustion in Baihui(DU20) on the hemodynamics of posterior cerebral artery in healthy people. Methods: Thirty cases of healthy male students between 20 and 22 years old were enrolled into this study. The V max (maximal velocity), V min (minimal velocity), PI(pulsatile index) and RI(resistant index) of bilateral posterior cerebral artery were measured. Results: The V max of right posterior cerebral artery(PRCA), PI and RI of right posterior cerebral artery (RPCA), the V min of right posterior cerebral artery and V max of left posterior cerebral artery raised significantly after moxibustion of Baihui(DU20)( P <0 01, P <0 01, P <0 05, P <0 05); The rest indexes hadn't any significant changes ( P <0 05). Conclusion: It suggests that moxibustion of Baihui(DU20) can raise the velocity of bilateral posterior cerebral artery in normal people.
