不同穴组对椎-基底动脉供血不足的协同或拮抗作用研究

目的:探讨针刺经穴(风池、天柱)、夹脊(C4～C6)对椎-基底动脉供血不足(VBI)的协同或拮抗作用.方法:采用自身对照的方法,对20例VBI患者分3次分别观察针刺经穴组、夹脊组、配伍组3个穴组对椎-基底动脉收缩期血流速度(vsys)的影响.结果:3组针刺后椎-基底动脉的vsys较针刺前相比均有显著性提高(P＜0.05,P＜0.01),但3组之间比较差异无显著性意义(P＞0.05).结论:针刺风池、天柱或C4～C6夹脊组或两者同用,均可使VBI患者椎-基底动脉的vsys值升高,改善椎-基底动脉的供血状况.但从即刻改善程度来说,两者之间未发现协同或拮抗作用.

Study on synergic or antagonistic effects of different acupoint groups on vertebro-basilar insufficiency

OBJECTIVE: To observe the synergic or antagonistic effect of needling acupoints Fengchi (GB 20) and Tianzhu (BL 10), and Jiaji C4-C6 (EX-B2) on vertebro-basilar insufficiency (VBI). METHODS: Self-control method was used and 20 cases of VBI were respectively treated with acupuncture at Fengchi (GB 20) and Tianzhu (BL 10), Jiaji (EX-B2). Their combination and the changes of vertebro-basilar artery's (VBA) systolic velocity of blood flow was detected. RESULTS: The VBA's systolic velocity of blood flow after acupuncture were increased in all the 3 groups (P < 0.05 or P < 0.01), with no significant difference among the 3 groups (P > 0.05). CONCLUSION: Acupuncture at Fengchi (GB 20) and Tianzhu (BL 10) or Jiaji (C4-C6 ) or their combination can increase VBA's systolic velocity of blood flow, improving blood supply of vertebro-basilar artery, but they have no synergic or antagonistic effects.
