【摘要】 目的:探讨电针阳陵泉穴对慢性胆囊炎患者胆囊容积及胆囊动脉血流动力学的影响。方法:50例慢性胆囊炎患者按随机数字表法分为试验组和对照组各25例,应用超声测量胆囊最大长径L、横径W及H,计算胆囊容积;运用CDFI测量胆囊动脉Vmax、Vmin、RI。试验组应用电针仪电针双侧阳陵泉穴,对照组电针假穴,电针穴位15 min、30 min后分别测量以上数据。结果:试验组电针阳陵泉穴后较电针前,胆囊容积、胆囊动脉Vmax、Vmin减小,RI增大,对照组各参数无明显变化。2组间比较差异有统计学意义。试验组电针穴位30 min后较电针15 min后上述参数变化更为显著,2组间比较差异有统计学意义。结论:电针阳陵泉穴可促进胆囊排空,胆囊动脉血流速度减慢,阻力指数增加,其机制可能为电针使胆囊平滑肌收缩。由于胆囊平滑肌收缩使胆囊动脉受压,胆囊动脉血流动力学产生相应变化。更多还原

【Abstract】 Objective To explore the effects of electroacupuncturing at Yanglingquan on volume and arterial hemodynamics of gallbladder in chronic cholecystitis. Methods: Fifty cases of chronic cholecystitis were measured the maximum diameter L,diameter W and H by ultrasonography,to calculate gallbladder volume. Vmax,Vmin,RI of gallbladder artery were measured with color Doppler flow imaging. All patients were electroacupunctured at Yanglingquan with BT701-1B electronaesthesia apparatus. All parameters were measured at 15 min,30min after electroacupuncturing,to calculate the gallbladder emptying rate and change of gallbladder artery hemodynamics. Results Volume and arterial Vmax,Vmin of gallbladder were decreased and RI increased after acupuncturing Yanglingquan than before,two groups had significant difference. All parameters changes more significantly at 30 min after acupuncturing Yanglingquan than 15 min,two groups had significant difference. Conclusion: Electroacupuncturing Yanglingquan can promote gallbladder emptying,decrease velocity of gallbladder artery,increase resistance index. The mechanism may be the gallbladder smooth muscle contraction after acupuncturing,gallbladder emptying. Because of the gallbladder smooth muscle contraction,the artery of gallbladder were resistance,and artery hemodynamics produce corresponding changes.更多还原
