摘要
目的:探讨电针风池穴对颈性高血压模型兔血压、颈动脉和椎动脉血流动力学指标的影响.方法:建立颈性高血压模型,将造模成功的12 只家兔按随机数字表法分为模型组和电针组,每组6 只,另选取6 只健康家兔作为正常组.对电针组家兔给予电针风池穴治疗,模型组和正常组家兔仅给予相同时间的固定.观察各组家兔椎动脉及颈动脉收缩期最大流速(peak systolic velocity,PSV)、舒张期最大流速(end-diastolic volume,EDV)、阻力指数(resistance index,RI)、股动脉收缩压(systolic blood pressure,SBP)变化.结果:与正常组比较,电针组家兔颈动脉收缩期血流速度[(61.30±9.62)cm/s]显著改善(P<0.05);与治疗前比较,电针组家兔股动脉收缩血压[(109.60±4.56)mm Hg]显著降低(P<0.05),模型组家兔股动脉收缩血压[(112.00±6.07)mm Hg]无明显变化.结论:电针风池穴可有效降低颈性高血压家兔血压,其降压作用可能与改善颈区血管血流动力学指标相关.
Abstract
Objective:To investigate the effects of electroacupuncture at Fengchi Point on blood pressure(BP),hemodynamics of carotid artery and vertebral artery in rabbits with cervical hypertension.Methods:A cervical hypertension model was established,and 12 rabbits with successful modeling were divided into a model group and an electroacupuncture group according to the random number table method,with 6 rabbits in each group.Six healthy rabbits were selected as the normal group.The rabbits in the electroacupuncture group were treated with electroacupuncture at Fengchi Point,while the rabbits in the model group and the normal group were only fixed for the same time.The changes of peak systolic velocity(PSV),end-diastolic velocity(EDV),re-sistance index(RI)and femoral artery systolic blood pressure(SBP)of vertebral artery and carotid artery in each group were observed.Results:Compared with the normal group,the carotid artery systolic blood flow velo-city of rabbits in the EA group was significantly improved[(61.30±9.62)cm/s],(P<0.05);compare with pro-treatment,the femoral artery systolic BP of rabbits in the EA group was significantly decreased[(109.60±4.56)mm Hg](P<0.05),the femoral artery systolic BP of rabbits in the model group was no significantly changed[(112.00±6.07)mm Hg].Conclusion:EA at Fengchi acupoint can effectively reduce the blood pressure of rab-bits with cervical hypertension,and its antihypertensive effect may be related to the improvement of hemodynamics indexes in the cervical region.
