目的:探讨电针手厥阴心包经穴对脑梗死恢复期患者脑血流动力学的影响。方法:采用随机、对照研究方法,将54例患者随机分为心包经组27例、Sham组27例。心包经组电针心包经穴(天泉、曲泽、内关、大陵),Sham组电针同节段非经非穴点,以电针前后大脑各动脉的经颅多普勒超声(TCD)参数作为观察指标。结果:心包经组大脑中动脉(MCA)的收缩期血流速度(Vp)、平均血流速度(Vm)、舒张末期血流速度(Vd),较电针前增快,差异均有统计学意义(P〈0.05,P〈0.01),且在改善MCA的Vp方面优于Sham组,差异有统计学意义(P〈0.05)。2组大脑前动脉(ACA)、大脑后动脉(PCA)、椎动脉(VA)及基底动脉(BA)的Vp、Vm、Vd、PI、RI及S/D各指标前后比较,组间比较,差异均无统计学意义(P〉0.05)。结论:电针心包经穴可促进MCA的血流速度,改善脑部供血。
Objective:To discuss the instant effect of electroacupuncture on pericardium channel of hand- jueyin meridian on patients with cerebral hemodynamics in cerebral infarction recovery period. Methods:Fifty- four cased of patients were divided into 27 cases of pericardium channel group and 27 cases of Sham group by the method of random and contrast study.Pericardium channel(Tianquan,Quze,Neiguan,Daling) were stimulated by electroacupuncture in pericardium channel group,the non- acupoint points on the same section were stimulated by electroacupuncture in Sham group. Transcranial Doppler(TCD) parameters of each artery in the brain before and after electroacupuncture were observed. Results:Blood velocity(Vp),average blood velocity(Vm) of middle cerebral artery(MCA) systole and blood velocity in diastasis(Vd) in pericardium channel group were all faster than those before electro- acupuncture,the difference being statistical significant(P〈0.05,P〈0.01).And those in the pericardium channel group was superior to those in sham group on improving Vp of MCA(P〈0.05).Conclusion: Stimulating the pericardium channel with electroacupuncture can promote the blood flow velocity of MCA and improve blood- supply in the brain.
