摘　　要：背景:中医药在治疗缺血性脑卒中痰热腑实证中具有丰富的经验和独特的优势,为深入挖掘中医药对该病的治疗靶点和治疗机制,建立稳定、可靠的缺血性脑卒中痰热腑实证病证结合动物模型是关键。目的:探讨缺血性脑卒中痰热腑实证大鼠模型的建立方法及评价体系。方法:采用随机数字表法将60只SD大鼠随机分为4组:空白对照组(n=12)、缺血性脑卒中组(n=18)给予普通饲料喂养25 d,病证结合组(n=18)、痰热腑实证组(n=12)给予高脂饲料喂养25 d;第26天,空白对照组、缺血性脑卒中组灌胃给予生理盐水,病证结合组、痰热腑实证组灌胃给予自体粪便混悬液,连续灌胃3 d(灌胃期间继续给予高脂饲料);灌胃结束后,缺血性脑卒中组、病证结合组采用线栓法建立缺血性脑卒中模型,记录各组大鼠饮食量、饮水量、体质量、体温、粪便性状、鼻分泌物、喉中痰鸣、舌象等表征变化。造模结束后24 h,进行神经功能缺损评分、舌象表征、血脂水平检测、脑组织及颈动脉形态学观察以及血清胃动素和生长抑素水平检测。结果与结论:(1)与空白对照组比较,病证结合组大鼠呼吸急促、精神萎靡、烦躁、行动迟缓,鼻周可见大量分泌物、可闻及厚重的喉中痰鸣,饮食量、饮水量下降,体质量、体温及舌下脉络评分升高,粪便粒数、Bristol评分及粪便含水率降低;血清总胆固醇、三酰甘油、低密度脂蛋白胆固醇及生长抑素水平升高,胃动素水平降低,神经功能缺损评分升高,颈动脉发生显著病理改变,脑组织显示明显缺血形态学改变。缺血性脑卒中组仅能造成缺血性脑组织病理改变,不能复制出痰热腑实证的证候特征。痰热腑实证组能复制出典型的中医证候特征,但不能构建出缺血性脑卒中的脑组织病理改变。(2)结果表明,高脂诱导结合线栓法及自体粪便灌胃的多因素复合造模方法,可建立缺血�BACKGROUND:Traditional Chinese medicine has rich experience and unique advantages in the empirical treatment of phlegm-heat and Fu-organs excess syndrome of ischemic stroke.In order to further explore the therapeutic targets and mechanisms of traditional Chinese medicine for this disease,it is crucial to establish a stable and reliable animal model of phlegm-heat and Fu-organs excess syndrome combined with empirical symptoms of ischemic stroke.OBJECTIVE:To explore the establishment method and evaluation system of the rat model of ischemic stroke with phlegm-heat and Fu-organ excess syndrome.METHODS:Sixty male Sprague-Dawley rats were randomly divided into four groups:blank control group(n=12),ischemic stroke group(n=18),disease+syndrome group(n=18),phlegm-heat and Fu-organ excess syndrome group(n=12),all of which were given high-fat diet for 25 days.On the 26th day,the rats in the blank control group and ischemic stroke group were intragastrically given normal saline and high fat diet,while those in the other two groups were intragastrically given autologous feces suspension and high fat diet for 3 continuous days.After gavage,ischemic stroke models were established using the suture method in the ischemic stroke group and disease+syndrome group.The changes in diet,water intake,body mass,body temperature,fecal traits,nasal secretions,sputum in the throat,and tongue image were recorded.Neurological deficits,tongue image,blood lipid levels,morphological changes of brain tissue and carotid artery,and the serum levels of motilin and somatostatin were detected.RESULTS AND CONCLUSION:Compared with the control group,the rats in the disease+syndrome group had shortness of breath,listlessness,irritability,bradykinesia,a large number of secretions around the nose,audible and heavy sputum in the throat,decreased diet and water intake,increased body mass,body temperature,and slingual vein score,decreased fecal pellet count,Bristol score and fecal moisture content,increased serum total cholesterol,triglyceride,low-density lipo
