To observe the effect of moxibustion of Baihui (GV 20) on the hemodynamics of internal carotid artery in health subjects so as to study its underlying mechanism of moxibustion in the treatment cerebrovascular disorders.
Thirty healthy male volunteer students between 20 and 22 years in age were enrolled into this study. Qm (mean blood flow), Vm) (mean velocity of blood flow), Vmax (maximal velocity of blood flow), Vmin (minimal velocity of blood flow), Wv (pulse wave velocity), Zcv (characteristic impedance), Rv (peripheral resistance), DR (dynamic resistance), CP (critical pressure) and DP (difference of pressure) of the right and left common carotid arteries were measured before and after moxibustion of GV20 (5-10 min each time, once daily, 5 times altogether) by using CBA CV-300 Cerebrovascular Hemodynamics Detector.
Following moxibustion of GV20, Qm, Vm and Vmin of both right and left common carotid arteries increased significantly (P < 0.01); while Rv and DR of the brain artery lowed evidently (P < 0.05); The rest indexes had no significant changes (P > 0.05).
Moxibustion of Baihui (GV 20) can significantly raise the velocity of blood flow of the common carotid artery and low the resistance of blood vessels.
观察艾灸百会穴（GV20）对健康受试者颈内动脉血流动力学的影响，以探讨艾灸治疗脑血管疾病的潜在机制。
选取30名年龄在20至22岁之间的健康男性志愿者学生参与本研究。使用CBA CV - 300脑血管血流动力学检测仪，在艾灸百会穴（每次5 - 10分钟，每日1次，共5次）前后，测量左右颈总动脉的Qm（平均血流量）、Vm（平均血流速度）、Vmax（最大血流速度）、Vmin（最小血流速度）、Wv（脉搏波速度）、Zcv（特征阻抗）、Rv（外周阻力）、DR（动态阻力）、CP（临界压力）和DP（压差）。
艾灸百会穴后，左右颈总动脉的Qm、Vm和Vmin均显著增加（P < 0.01）；脑动脉的Rv和DR明显降低（P < 0.05）；其余指标无显著变化（P > 0.05）。
艾灸百会穴（GV20）可显著提高颈总动脉的血流速度，降低血管阻力。
