针刺耳胰胆穴对慢性胆囊炎患者胆囊动力学的影响

Influence of Acupuncture at Pancreas-gallbladder Point in Auricular Therapy on Gallbladder Dynamics of Chronic Cholecystitis Patients

目的观察留针时间长短对慢性炎性胆囊运动的影响规律,为确定最佳留针时间、针刺频次提供参考依据。方法将22例慢性胆囊炎患者随机分为30min组和60min组各11例,两组均针刺双耳胰胆穴,分别以中等强度刺激手法捻转行针30s后留针,留针期间每隔10min用同等强度刺激手法捻转行针,每侧穴位30s,两组分别留针30min、60min。分别记录针刺前5min,针刺后10、20、30、40、50、60min时胆囊容积的大小及胆囊收缩率。结果 30min组在针刺后20min时,胆囊容积与针刺前5min比较差异有统计学意义(P<0.05);60min组在针刺20、40、50min时胆囊容积与针刺前5min比较差异均有统计学意义(P<0.05)。两组患者针刺前30min胆囊容积减值幅度变化基本一致,均在针刺后20min时达到收缩的峰值,针刺后30min胆囊容积减值幅度60min组强于30min组,并于留针40min后维持一种稳定的张力状态。两组间不同时间点胆囊容积及胆囊收缩率组间比较差异均无统计学意义(P>0.05)。结论针刺耳廓胰胆穴能够明显促进慢性炎性胆囊的张力性舒缩运动,其最佳留针时间为40min,针刺频次以每天2次为宜。

Objective To observe the influence of needle-retaining duration of auricular acupuncture on the movement of chronic inflammatory gallbladder for providing the reference for the best needle-retaining time and frequency of acupuncture.Methods Twenty-two chronic cholecystitis patients were randomized into the 30min group and 60min group with 11 cases in each.Both groups were treated with auricular acupuncture at pancreas-gallbladder point of both sides.The needles were manipulated with moderate stimulation of rotating for 30s and then retained.In the duration of needle-retaining,the needles were rotated once every 10min with moderate stimulation for 30s each side.The retaining time for one group was 30min and for the other was 60min.The gallbladder volume 5min before acupuncture and 10,20,30,40,50,and 60min after acupuncture was recorded and the contraction rate was calculated.Results In the 30min group,the gallbladder volume 20min after acupuncture was statistically different from that of 5min before acupuncture（P0.05）.In the 60min group,the gallbladder volume at the time points 20,40,and 50min after acupuncture was statistically different from that of 5min before acupuncture（P0.05）.The reduction amplitude of gallbladder volume of both groups in the first 30min was the same,and it reached the peak value of contraction 20min after acupuncture,while at the time point 30min after acupuncture,the reduction amplitude in the 60min group was stronger than that in the 30min group.A stable tension state of gallbladder was maintained after 40min needle-retaining.In the comparison between the two groups,there was no statistical difference in the gallbladder volume and contraction rate at different time points（P0.05）.Conclusion Auricular acupuncture at pancreas-gallbladder point could significantly promot the systaltic movement of the chronic inflammatory gallbladder.The best needle-retaining time is 40min,and the advisable frequency of acupuncture is twice a day.
