针刺左侧列缺穴对大脑前动脉血流动力学影响的研究

Research on Hemodynamic Effects of Acupuncture on Left Lieque(LU7) on the Arteria Cerebri Anterior

目的探讨针刺左侧列缺穴对健康青年大脑前动脉(ACA)的血流动力学影响,并探究列缺穴对不同性别受试者ACA的影响,为临床选取该穴治疗脑血管病提供依据。方法选取健康青年30例,分为3组进行试验,分别为男女混合组30例、女性组15例、男性组15例。针刺受试者左侧列缺穴,在针刺前(针刺前10 min)、入针后(进针得气时)、行针时(留针15 min)、出针时(留针30 min)、出针后(出针后10 min)运用TCD分别记录志愿者双侧ACA的血流动力学改变。结果 (1)男女混合:针刺左侧列缺穴,在出针时,双侧ACA的舒张期最大血流速度(Vd)较针刺前显著增加(P<0.05)。(2)女性:针刺左侧列缺穴,在出针时,双侧ACA的舒张期Vd较针刺前显著增加(P<0.05)。(3)男性:针刺左侧列缺穴,在出针10 min后,左侧大脑前动脉PI与行针时比较有所增加(P<0.05)。结论针刺左侧列缺穴可增加健康青年双侧ACA血流速度,其中女性结果明显优于男性。列缺穴可作为女性ACA缺血性疾病的首选治疗穴位。男性选穴意义不大。

Objective： To investigate the hemodynamic effects of acupuncture on left Lieque（LU7） on the arteria cerebri anterior in healthy young subjects and different gender and to provide the basis for cerebrovascular disease therapy. Methods： 30 healthy volunteers were randomly divided them into three groups including the mixed group with 30 cases,the female group with 15 cases and the male group with 15 cases.Needled the left Lieque（LU7） and detected the ACA hemodynamic changes on both sides with TCD and recorded the results at these following points： 10 min before the needle,needle into the body and feel sour,numb,dilate and ache,manipulate the needle（retaining needle for 15min）,withdraw the needle（retaining needle for 30 min）,10 min after needle. Results：（1）The mixed group：bilateral ACA′ s diastolic blood flow velocity（Vd） became significantly faster at the time of withdrawing the needle than that before the acupuncture（P〈0.05）.（2）The female group： bilateral ACA′s diastolic blood flow velocity（Vd） became significantly faster at the time of withdrawing the needle than before the acupuncture（P〈0.05）.（3）The male group：the left ACA′s pulsatility index（PI） was increased at the time of withdrawing the needle after 10 min than manipulating the needle（P〈0.05）. Conclusion：（1）The mixed group：needling left Lieque（LU7） is able to increase the bilateral ACA′s brain blood stream and has a positive influence on ACA′s hemodynamics.（2）The female group： needling left Lieque（LU7） is able to increase the bilateral ACA′s brain blood stream.（3）Male group： needling left Lieque（LU7） is able to increase the left ACA＇s pulsatility index. It has an effect of contracting ACA′s blood vessel of males.
