摘要
目的:观察针刺足三里“得气”的自主神经效应。方法:以84例健康青年女性为试验对象,将其随机分配至得气组、不得气组和空白组。得气组针刺右侧足三里,深度2.5 cm左右,提插得气,行针5 min后出针;不得气组针刺足三里,深度0.4 cm,不提插,不得气。两组于针刺前、针刺后即刻、30 min与60 min行心率变异检测。空白组不做任何干预,也在相应时段行心率变异(HRV)检测。指标包括:总功率对数(ln TP)、极低频对数(ln VLF)、低频对数(ln LF)、高频对数(ln HF)和低/高频比值对数(ln LF/HF)。针感强度采用麻省总医院针感量表(MASS)评估。结果:干预后即刻与干预前差值,得气组与不得气组、空白组比较,ln TP、ln VLF和ln LF显著升高,差异具有统计学意义(P<0.05或P<0.01);与空白组比较,ln HF显著升高,差异具有统计学意义(P<0.05或P<0.01),与不得气组比较,ln HF比较差异无统计学意义(P>0.05)。在其余时段,各组间HRV的各项指标比较差异无统计学意义(P>0.05)。得气组干预后即刻的得气强度和各指标之间无显著相关性(P>0.05)。结论:健康女性针刺得气的即刻以交感神经兴奋为主。得气的自主神经效应与是否得气有关,但是与得气的强度无明显相关性。
Objective:To observe the autonomic nerve effect of‘Deqi’by needling ST36.Methods:84 healthy young women were randomly divided into the Deqi group,the non-Deqi group and the blank group.The Deqi group was intervened by needling Zusanli(ST36),the needling depth was approximately 2.5 cm,and Deqi sensation was achieved by lifting and inserting the needle for 5 minutes before withdrawing the needle.The non-Deqi group was intervened by needling ST36,the needling depth was 0.4 cm without manipulation or Deqi sensation.Heart rate variability(HRV)test was applied for both groups before the insertion,right after needling,after 30 min and 60 min of needling.The blank group was not given any intervention,but also underwent HRV test in the corresponding period.The parameters of heart rate variability include natural logarithm of total power(ln TP),natural logarithm of very low frequency(ln VLF),natural logarithm of low frequency(ln LF),natural logarithm of high frequency(ln HF)and natural logarithm of LF/HF(ln LF/HF).Needle sensation intensity was assessed by the Massachusetts General Hospital Acupuncture Sensation Scale(MASS).Results:The difference between immediately after intervention and before intervention,ln TP,ln VLF and ln LF were significantly increased in the Deqi group compared with those in the non-Deqi group and the blank group(P<0.05,P<0.01).Compared with that in the blank group,the ln HF was significantly increased(P<0.05,P<0.01),but there was no statistical difference in ln HF between the Deqi group and the non-Deqi group(P>0.05).In other periods,there was no statistical difference in the HRV parameters among the groups(P>0.05).There was no significant correlation between the Deqi intensity and the parameters in the Deqi group immediately after the intervention(P>0.05).Conclusion:The Deqi sensation of healthy women during acupuncture leads to the excitation of sympathetic nerve immediately.The autonomic nerve effect of Deqi is related to whether Deqi is obtained,but has no obvious correlation with the inte
