        摘   要   目的 探究芎麻汤有效部位防治肝阳上亢兼瘀血型偏头痛的作用机制。方法 70只雄性SD大鼠按体质量随机分为正常
        组、模型组、阳性对照组(盐酸氟桂利嗪胶囊0.9 mg/kg)及芎麻汤有效部位低、高剂量组(乙酸乙酯提取物0.87、3.46 g/kg,正丁醇提取
        物1.80、7.20 g/kg)。除正常组外,其余各组大鼠灌胃附子汤(2 g/kg),每天1次,连续4周,复制肝阳上亢证模型;造模第15天,各给药
        组同时灌胃相应药物,每天1次,连续2周;造模第29天,电刺激大鼠三叉神经节复制肝阳上亢兼瘀血型偏头痛模型后,按前述方
        法再维持给药1次。观察大鼠宏观体征及行为表现;取大鼠三叉神经颈髓复合体(TCC),分别采用免疫组织化学法、RT-qPCR法、
        Western blot法检测瞬时受体电位香草酸亚型1(TRPV1)、降钙素基因相关肽(CGRP)、降钙素受体样受体(CRLR)、活性修饰蛋白
        受体1(RAMP1)的阳性表达、mRNA及蛋白相对表达量。结果 模型组大鼠出现肝阳上亢兼瘀血型偏头痛相关的宏观体征及行为
        表现。末次给药30 min后,芎麻汤有效部位各组大鼠以上情况均明显改善。与正常组相比,模型组大鼠TCC内TRPV1、CGRP、
        CRLR、RAMP1阳性表达、mRNA及蛋白相对表达量均显著升高(P<0.05)。与模型组相比,芎麻汤有效部位各组大鼠TCC内上
        述指标大部分显著降低(P<0.05)。结论 芎麻汤防治肝阳上亢兼瘀血型偏头痛的作用机制可能与抑制 TCC 内 TRPV1-CGRP/
        CGRP受体信号通路的活性有关。

        ABSTRACT    OBJECTIVE To explore the mechanism of effective fractions from Xiongma decoction in the treatment of migraine
        with hyperactivity of liver-yang and blood stasis. METHODS Totally 70 male SD rats were randomly divided into normal group,
        model group,positive control group(Flunarizine hydrochloride capsules 0.9 mg/kg),low-dose and high-dose groups of Xiongma
        decoction effective fractions(ethyl acetate extract 0.87,3.46 g/kg,n-butanol extract 1.80,7.20 g/kg). Except for normal group,
        rats in other groups were given aconite decoction(2 g/kg),once a day,for 4 consecutive weeks to establish the hyperactivity
        model of liver-yang. On the 15th day of modeling,all administration groups were given corresponding drugs intragastrically at the
        same time,once a day,for 2 consecutive weeks. On the 29th day of modeling,rats trigeminal ganglion was stimulated to establish
        the migraine model with hyperactivity of liver-yang and blood stasis,then the medication was maintained for another time
        according to the above method. The macroscopic signs and behavior of the rats were observed;positive expression,mRNA and
        protein expression of transient receptor potential vanilloid 1 (TRPV1),calcitonin generelated peptide (CGRP),calcitonin
        receptor-like receptor (CRLR) and receptor-associated membrane proteins 1 (RAMP1) in trigeminal cervical spinal complex
        (TCC) were detected by immunohistochemistry,RT-qPCR and Western blot assay. RESULTS Rats in model group showed
        macrophysical signs and behavioral manifestations related to migraine with hyperactivity of liver-yang and blood stasis. Thirty
