“龙虎交战”针法针刺八脉交会穴对偏头痛患者头痛天数及血清CGRP表达的影响＊

目的 观察“龙虎交战”针法针刺八脉交会穴对无先兆偏头痛（Migraine without aura，MO）患者头痛天数及外周血降钙素基因相关肽（Calcitonin gene related peptide，CGRP）表达水平的影响。方法 按照头痛程度将90例MO受试者区层随机分为治疗Ⅰ组、治疗Ⅱ组和对照组各30例。治疗Ⅰ组施以“龙虎交战”针法针刺八脉交会穴（外关和足临泣），治疗Ⅱ组施以平补平泻针法针刺八脉交会穴（外关和足临泣），对照组施以平补平泻针法针刺非经非穴点，每次留针30分钟，5次/周，共治疗20次。于治疗前、治疗结束4周后的随访分别记录三组患者头痛天数的变化情况以判定疗效，并采集患者治疗前、治疗结束4周后随访的肘部静脉血用ELISA法检测血清中的CGRP含量的变化。结果 ①各组治疗前患者的头痛天数无显著差异（Ｐ > 0.05），治疗Ⅰ组、治疗Ⅱ组和对照组治疗结束4周后随访的头痛天数较治疗前均显著降低（Ｐ < 0.05）；治疗Ⅰ组头痛天数的降低显著优于治疗Ⅱ组和对照组（Ｐ < 0.001），治疗Ⅱ组头痛天数的降低显著优于对照组（Ｐ < 0.05）；②3组治疗前CGRP的表达无显著差异，治疗Ⅰ组、治疗Ⅱ组治疗结束4周后随访CGRP的表达较治疗前均显著下降（Ｐ < 0.001），对照组治疗结束4周后随访CGRP的表达较治疗前差异无显著性（Ｐ > 0.05）；治疗Ⅰ组CGRP治疗结束4周随访的表达较治疗Ⅱ组和对照组均显著下降（Ｐ < 0.01），治疗Ⅱ组CGRP的表达较对照组显著下降（P < 0.01）。结论 ①八脉交会穴施以“龙虎交战”针法针刺能明显改善MO患者的头痛天数，同时降低MO患者血清CGRP的表达水平，这可能是针刺八脉交会穴治疗MO的机制之一；②非经非穴点的针刺效应无持续性，而八脉交会穴的针刺效应具有持续性；③八脉交会穴可以充分发挥复式针刺手法的治疗效应，提示我们在临床上治疗疾病时不仅要注意腧穴配伍，恰当的针刺手法更是提高临床疗效、事半功倍的关键。     

Gender ratio of migraine without aura: observations over time

Abstract Migraine without aura is typically considered a female condition. The purpose of this study was to determine if there have been any changes in the female-to-male ratio of the disease over time. We included in the study all patients with migraine without aura (n=3457) referred to the Parma University Headache Centre between 1976 and 1995. They were divided into subgroups with respect to gender and year-range of onset of migraine (before 1960, in the 1960s, in the 1970s, in the 1980s, and between 1990 and 1995). Gender ratio ranged from 3.6:1 (in patients with onset before 1960) to 2.8:1 (in patients with onset in the 1980s), with no statistically significant changes during the observation period.     

Rare diseases mimicking acute vertebrobasilar artery thrombosis

Acute ischaemia of the vertebrobasilar circulation leads to a variety of clinical manifestation and is mostly due to cardiogenic or artery-to-artery embolism. We describe four neurological emergency situations involving vertebrobasilar artery aclusion of other origins: basilar migraine, extrinsic compression by rheumatoid inflammatory tissue, generalized vasculitis in subacute rheumatic fever and basilar artery dissection. The differential diagnosis of acute vertebrobasilar artery occlusion may have an important impact on patient management.     

MELAS presenting as migraine complicated by stroke: case report

A case of MELAS (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) which presented as migraine complicated by stroke is reported. Strokes associated with migraine have often been reported, but the mechanism remains unclear and may include a variety of pathologies. MELAS also presents with migrainous headache, vomiting, and stroke-like symptoms. Magnetic resonance imaging demonstrates characteristic findings. MELAS should be considered in the differential diagnosis of infarct-like lesions with migrainous headaches in young adults, especially if the symptoms fluctuate and are accompanied by a homonymous hemianopia.

针刺对偏头痛大鼠脑内一氧化痰、5-羟色胺的影响

目的 :观察针刺对偏头痛大鼠脑内一氧化氮 (NitricOxide,NO)和 5 -羟色胺 (Sereotonin ,5 -HT)的影响 ,并探讨其防治偏头痛的作用机制。方法 :将 4 0只大鼠随机分为正常对照组、模型组、针刺预防组和针刺治疗组 ;采用硝酸还原法和反相高效液相色谱法分别测定颈静脉 (ExternalJugularVein ,EJV)中NO和 5 -HT含量。结果 :与正常对照组比较 ,模型组NO显著升高 ,5 -HT显著降低 (P <0 .0 1) ;与模型组比较 ,针刺预防组和针刺治疗组NO显著降低 (P <0 .0 1) ,5 -HT明显升高 (P <0 .0 1)。结论 :针刺不仅能治疗偏头痛 ,而且能减慢 5 -HT的降解 ,抑制NO的释放。推测针刺偏头痛可能是通过调节 5 -HT和NO的含量而实现的。     

偏头痛和慢性紧张型头痛血浆精氨酸加压素、催产素及环核着酸含量测定

用放射免疫分析法测定了２８例偏头痛、１０例慢性紧张型头痛患者和１６例健康对照组血浆精氨酸加压素（ＡＶＰ）、催产素（ＯＴ）、环磷酸腺苷（ｃＡＭＰ）及环磷酸鸟苷（ｃＧＭＰ）含量。结果表明，偏头痛发作期ＡＶＰ含量下降、ｃＡＭＰ含量升高，偏头痛间歇期ｃＧＭＰ含量下降，血浆ＯＴ含量在发作期和间歇期均明显下降。慢性紧张型头痛患者血浆ＡＶＰ、ＯＴ、ｃＡＭＰ和ｃＧＭＰ与对照组比较均无显著性差异。结果提示，血浆ＡＶＰ和ＯＴ水平降低以及环核苷酸的代谢异常与偏头痛发病机制有关。
