电热砭石对手背局部皮肤血流影响的试验研究

Experimental study on effect of electro-heated stone needle on local skin blood perfusion of dorsum hand

[目的]观察电热砭石对手背局部皮肤血流灌注的影响,探讨砭石疗法的作用机制。[方法]45℃电热砭石刺激健康受试者右手第3、4掌骨间,运用激光多普勒血流成像系统观察刺激前和刺激后不同时间段右手皮肤血流和脐周血流。[结果]在接受电热砭石刺激后,右手血流显著上升(P<0.01)。在30min内,升高的血流未见明显衰减,和接受刺激前比(P<0.01)。对照组在接受刺激后30min内,脐周血流无明显变化。[结论]电热砭石刺激能显著提高刺激局部手背皮肤血流,而对脐周血流无明显影响。

[Objective] To observe the effect of electro-heated stone needle on the blood perfusion of dorsum of hand and to investigate the mechanism of the therapy. [Methods] Stimulation the third and 4th interosseous space of metacarpus of right hand by the 45℃ stone needle was performed and then the change of blood perfusion in the area of dorsum of hand and periumbilicus was observed with laser Doppler blood perfusion imaging system. [Results] After stimulation, the blood perfusion of right hand increased markedly （compared with pre-stimulation, P〈0.01 ）, and the attenuation of the increased blood perfusion was not noted within 30 minutes after stimulation. On the other hand, there was not significant change of the blood perfusion in periumbilicus area within 30 minutes after stimulation. [Conclusion] Electro-heated stone needle therapy can increase skin local blood perfusion of dorsum of hand without any effect on the periumbilicus area.
