目的:探讨针灸预处理诱导热休克蛋白(HSP)表达对心肌缺血再灌注损伤(MIRI)兔延迟保护作用的机制。方法:新西兰大耳白兔随机分为假手术组、模型组、电针组和艾灸组,每组18只,各组按预处理后不同时相再分为0、24、48 h 3个亚组,每组6只。电针组及艾灸组造模前电针或艾灸"内关",每次20 min,每日1次,共治疗5 d。各组于预处理5 d后0、24、48 h行冠脉结扎法复制心肌缺血再灌注模型。HE染色观察左心室肌病理变化,电镜观察左心室肌超微结构变化。免疫组化法检测兔心肌组织HSP 27、HSP 70、HSP 90的表达。结果:各组预处理家兔的HE染色及超微结构结果显示,与假手术组比较,模型组心肌损伤较严重,肌纤维紊乱...

OBJECTIVE: To observe the effect of electroacupuncture (EA) and moxibustion (Moxi) pretreatment on expression of myocardial heat shock protein (HSP) in acute myocardial ischemia-reperfusion injury (MIRI) rabbits. METHODS: A total of 72 New Zealand rabbits were randomly divided into 4 groups:sham operation, MIRI model, EA pretreatment and Moxi pretreatment (n=18 rabbits in each group) which were further divided into 0, 24 and 48 h (time-point) subgroups (n=6 in each). The MIRI model was established by occlusion of the anterior descending branch (ADB) of the left coronary artery for 40 min and r...
