摘要
目的:研究头排针治疗脑梗死过程中颈动脉血液动力学指标以及血流能量的变化。方法:选取20例脑梗患者作为研究对象,在头排针治疗前后用脑循环分析检测其颈动脉处血流动力学参数,包括平均流速(Vmean)、最大流速(Vmax)、最小流速(Vmin)、平均血流量(Qmean)、最大血流量(Qmax)、最小血流量(Qmin)、特性阻抗(Zc)、外周阻力(Rc)、动态阻力(Dr)、临界压力(Pc),通过计算得到颈动脉能量指标,包括稳定势能(Ws)、振荡势能(Wo)、总势能(Wc)、稳定动能(Ks)、振荡动能(Ko)、总动能(Kc)、稳定总能(Ts)、振荡总能(To)、总能量(Tc)、振荡总能与总能量的比率(RO/T)、总动能与总能量的比率(RK/T)、振荡势能与总势能的比率(RWO)以及振荡动能与总动能的比率(RKO)。结果:头排针治疗后,脑梗患者颈动脉的血流速度以及血流量均有显著升高(P<0.001),Rc显著降低(P<0.001),各稳定能与总能量的值均有明显增加(P<0.001),但振荡总能与总能量的比率无明显变化。结论:头排针治疗能在短期内增加颈动脉血流量,提高为脑循环供给的总能量,改善微循环指标,但颈动脉系统总能效率在治疗后无显著变化。
Objective To observe the changes of carotid hemodynamic and hydraulic power indices after paralleled scalp-point acupuncture therapy in post-stroke patients. Methods Twenty post-stroke volunteer patients were enlisted in the present study. Aseptic filiform needles were inserted into Baihui （GV 20）, bilateral Motor Area （MS 8）, etc. with the needles retained for 5 min. The treatment was given one time. Hemodynamic indices： mean velocity of blood flow （Vmean ）, maximum velocity （Vmax）, minimum velocity （Vmin） , mean blood flow （Q mean）, maximum blood flow （Qmax）, minimum blood flow （Qmin）, natural impedance （Zc）, peripheral resistance （Rc）, dynamic resistance （Dr）, and critical pressure （Pc） before and after the treatment were detected with KF-3000 Brain Circulation Analyzer. The hydraulic power indices：stable potential energy （ Ws）, oscillation potential energy （ We）, total potential energy （ Wc）, stable kinetic energy （Ks）, success kinetic energy （Ko）, total kinetic energy （Kc）, stable total energy （Ts）, oscillation total energy （To）, total energy （Tc）, To/Tc, Kc/Tc, We/Wc and Ks/Kc were obtained through calculation. Results After the therapy, Vmin, Vmean, Qmin and Qmean increased significantly （ P〈0. 001）, while Rc decreased evidently （P〈0. 001）. Ws, Ks, Ts, Wc, Kc, Tc and Kc/Tc increased obviously （P〈0. 001, P〈0.05）, and Ks/Kc declined significantly （P〈0.01）. The rest indices had no significant changes after the treatment. Conclusion Multiple paralleled scalp acupuncture needles stimulation can effectively raise the blood flow volume of the common caroitid artery, leading to an increase of the energy supply of the cerebral blood circulation, but has no apparent influence on the total oscillatory energy/total energy in stroke patients.
