摘要:

针刺水沟穴治疗脑卒中有较好的临床效果,但其机制并不明确。为此,实验设计每天给予缺血再灌注脑梗死模型大鼠水沟穴15Hz、1mA、双相脉冲连续波、持续5min的电针干预至实验结束。见电针能有效提升了缺血再灌注脑梗死大鼠梗死侧和对侧的脑血流量,增加梗死灶及其周围Lectin及血管数量,上调内皮细胞标志物Von Willebrand因子和细胞增殖标志物Ki67表达,降低了大鼠神经功能损害程度评分。表明电针水沟穴能促进侧支循环建立和血管生成,进而改善神经功能。

Abstract:

Acupuncture at Shuigou (GV26) shows good clinical efficacy for treating stroke, but its mechanism remains poorly understood. In this study, a cerebral infarction model of ischemia/reperfusion injury received electroacupuncture at GV26 (15 Hz and 1 mA, continuous wave [biphasic pulses], for 5 minutes). Electroacupuncture effectively promoted regional cerebral blood flow on the infarct and non-infarct sides, increased infarct lesions, lectin, and number of blood vessels, upregulated von Willebrand factor and cell proliferation marker Ki67 expression, and diminished neurological severity score. These findings confirm that electroacupuncture at GV26 promotes establishment of collateral circulation and angiogenesis, and improves neurological function.
