作者: 浏览数: 关键词: 气虚 冠心病 大鼠 模型 建立

[摘要] 对单纯结扎冠状动脉、控制饮食复合结扎冠状动脉、疲劳跑步复合结扎冠状动脉、控制饮食+疲劳跑步双因素复合结扎冠状动脉4种方法建立的冠心病气虚血瘀证病证结合大鼠模型进行比较。该实验选用Wistar雄性大鼠,随机分为假手术组(SHAM)、单纯结扎冠脉组(L)、控制饮食复合结扎冠状动脉组(DL)、疲劳跑步复合结扎冠状动脉组(EL)、控制饮食+疲劳跑步双因素复合结扎冠脉组(DEL)。L组进行单纯冠脉结扎;DL组通过2周控制饮食造成脾胃气虚为主的全身气虚大鼠模型,在此基础上结扎冠脉,术后继续控制饮食;EL组通过2周跑台运动造成大鼠全身气虚模型,在此基础上进行冠脉结扎,术后以1次/2 d的频率维持力竭跑步;DEL组通过2周控制饮食、跑台运动造成大鼠全身气虚模型,在此基础上进行冠脉结扎,术后继续控制饮食并以1次/2 d的频率维持力竭跑步;于术后4周观察大鼠宏观体征,分别采集大鼠超声心动检测指标、呼吸幅度对大鼠冠心病气虚血瘀证的主症进行评价;采集空场实验相关指标、力竭运动时间、足底图像色彩饱和度对兼症进行评价;采集舌面色彩饱和度对舌象进行评价;采集脉搏搏动幅度对脉象进行评价。同时对脑钠肽、内皮素等指标进行检测。结果显示术后4周,通过疲劳运动复合结扎冠脉方法建立的模型与其他3种方法建立的模型比较与临床病因学基础以及与中医相关理论体系的联系更密切,在完整体现中医证候的特征方面具有一定的优势,更符合临床实际发病的原因与特征,是一种条件可控、重复性好的冠心病气虚血瘀证病证结合大鼠模型。

[Abstract] This paper was aimed to establish a method for coronary heart disease in rats with Qideficiency and blood stasis of the stable by comparing different model establishment methods (L group: ligation of coronary artery, EL group: exercise fatigue combine ligation of coronary artery, DL group: diet combine ligation of coronary artery, DEL group: diet, exercise fatigue combine ligation of coronary artery). After 6 weeks postoperatively, both the method of L (ligation of coronary artery) and DL, EL, DEL (multioriginated information complex) could be successfully established by coronary heart disease model of Qideficiency and bloodstasis syndrome type in rats. Model set up by using the compound factors (DL, EL, DEL), and through simple ligation of coronary artery to build model (L) to compare the clinical etiology and linked, DL, EL and DEL were more closely with relevant theoretical system of traditional Chinese medicine (TCM) and have a certain advantage in complete reflect the characteristics of TCM syndrome. Among three kinds of compound factors model, EL model compared with other two models DL and DEL was more consistent with clinical practical reasons and characteristics of the disease. Through EL the CHD deficiency of blood stasis rat model of combined disease could be controlled and good repeated.
