摘要
目的:探讨艾灸百会穴治疗脑血管病的可能机制。方法:选择健康本校男性学员30名,年龄20—22岁之间,应用上海麦登电子设备有限公司生产的脑血管血液动力学分析仪(CBACV-300型),探头频率5MHz,由固定专人操作,分别于艾灸治疗前及艾灸治疗后,测试脑血管血液动力学各项指标。结果:艾灸百会穴5d后,脑血管血液动力学分析报告显示:被检测者收缩压、舒张压及心率虽有不同程度的变化,但无统计学意义(P〉0.05);左侧颈总动脉血液Qmean(平均流量)、Vmean(平均流速)及Vmin(最小流速)增加显著(P〈0.01),脑血管Rv(外周阻力)、DR(动态阻力)明显降低(P〈0.05)。结论:艾灸健康人百会穴,可使颈总动脉血流速度明显加快,脑部外周小血管及毛细血管阻力明显降低,脑部血液供应明显改善。这对揭示艾灸百会穴治疗缺血性脑血管病的机理具有重要意义。
Objective : To study the effects of moxibustion of Baihui ( DU20 ) on the hemodynamics of common carotid artery (internal carotid artery) in health subjects. Methods: Thirty cases of healthy male students between 20 and 22 years in the age were enrolled into this study. Qmean ( mean blood flow), Vmean ( 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 left common carotid artery were measured before and after moxibustion of GV- 20 (50--10min each time, once daily, 5 times altogether) by using CBA CV-300 Detector of hemodynamics. Results: Following moxibustion of GV - 20, Qmean ( mean blood flow ), Vmean ( mean velocity of blood flow) and Vmin ( minimal velocity of blood flow) of left common carotid artery increased significantly (P 〈0. 01 ); Rv (peripheral resistance) and DR (dynamic resistance) of brain artery lowed signifi- cantly after moxibustion of Baihui (GV -20) (P 〈 0. 05 ) ; The rest indexes hadn't any significant changes (P 〉 0.05 ). Conclusion : moxibustion of Baihui ( GV - 20) can significantly raise the velocity of blood flow of common carotid artery, low the resistance of blood vessel.
