中文摘要：

目的观察按经选穴针刺对失眠大鼠下丘脑-垂体-肾上腺皮质（HPA）轴相关激素含量及腧穴配伍效应的影响,探讨针刺治疗失眠症的作用机制。方法腹腔注射对氯苯丙氨酸混悬液建立失眠模型大鼠。将60只SD大鼠随机分为空白组、模型组、百会＋神门组、百会＋三阴交组、百会＋非经非穴组,每组12只。各治疗组针刺相应腧穴,每次30 min,连续7 d。ELISA检测下丘脑促肾上腺皮质激素释放激素（CRH）及血清促肾上腺皮质激素（ACTH）、皮质酮（CORT）的含量。结果与模型组比较,各针刺组大鼠下丘脑CRH及血清ACTH、CORT的含量均有一定程度降低;各针刺组间比较,百会＋神门组的疗效优于百会＋三阴交组及百会＋非经非穴组。结论针刺可能通过调节HPA轴相关激素水平起到镇静安神的作用,按经选穴针刺可能是影响腧穴配伍效应的影响因素之一。

英文摘要：

Objective To observe the effects of acupuncture treatment on the levels of HPA axis related hormones and acupoint compatibility in insomnia rats; To discuss the mechanism of action for acupuncture treatment. Methods Chlorophenylalanine suspension was under intraperitoneal injection to establish insomnia model rats. Sixty SD rats were randomly divided into blank group, model group, Baihui＋Shenmen group, Baihui＋Sanyinjiao group, Baihui＋non-acupoint group, with 12 rats in each group. Each treatment group received acupuncture in relevant acupoints, 30 min each time, for 7 d. ELISA was used to measure the levels of CRH, ACTH and CORT. Results Compared with the model group, the levels of CRH, ACTH and CORT of the acupuncture groups decreased to some extent. In the three acupuncture groups, the efficacy of Baihui＋Shenmen group was better than that of Baihui＋Sanyinjiao group and Baihui＋non-non-acupoint group. Conclusion Acupuncture treatment may calm and soothe the nerves to release the insomnia through regulating HPA axis related hormones. Acupuncture acupoints at different meridians may be one of the factors that cause the difference of acupoints compatibility effect.
