【摘要】 目的:观察拔罐后罐斑组织的血流动力学变化,探讨拔罐疗法的可能作用机制。方法:采用高频彩色多普勒超声技术,于拔罐前后测量22例门诊腰痛患者同一部位共32个罐斑的皮下小动脉收缩峰值血流速度(PSV)、舒张末期血流速度(EDV)及阻力指数(RI),比较分析拔罐前后罐斑组织的血流参数及血流信号变化。结果:拔罐后罐斑组织的PSV、EDV较拔罐前明显增快,拔罐后罐斑组织的RI较拔罐前下降(均P<0.01)。彩色多普勒血流显像显示的罐斑组织血流信号较拔罐前明亮、丰富。结论:拔罐可明显改善病变部位的血流动力学,罐斑组织的血流动力学变化是拔罐"吸拔泵"作用的结果,是拔罐独特疗效的作用机制之一。更多还原

【Abstract】 Objective To observe hemodynamic changes in the local sucked tissue of lower back undergoing negative pressure after cupping in patients with lumbago.Methods Twenty-two lumbago outpatients were recruited in the present study and 32 sucked tissues accepted measurements.The cupping was applied to the tenderpoint of the patients’ lower back for 10 min by using a glass-mug(5 cm in diameter).Hemodynamic indexes [peak systolic velocity(PSV),end-diastolic velocity(EDV) and resistance index(RI)] of the sucked skin and subcutaneous tissues at the lower back were detected before and after cupping by using a color Doppler flow imaging.Results After cupping intervention at the lower back,the PSV[(14.2±1.8) cm/s] and EDV [(5.5±0.7) cm/s] levels were increased significantly in comparison with those [(5.9±0.9) and(1.9±0.3) cm/s] before cupping(P<0.01),while RI was reduced evidently after cupping(0.61±0.05 vs 0.68±0.06,P<0.01),suggesting an increase of the regional blood flow.Conclusion Cupping therapy can increase the peak systolic velocity and end-diastolic velo-city and lower vascular resistance of the subcutaneous arterioles in the regional tissue,which may contribute to its effect in relieving lumbago.更多还原
