【摘要】 目的:探究清热燥湿方保留灌肠对大肠湿热型溃疡性结肠炎大鼠模型Th1/Th2的影响。方法:选取SD成年大鼠40只,SPF级,体重180~200 g,湖南中医药大学动物实验中心提供,雌雄各半,适应性喂养1周后随机分为四组:A组(正常组)、B组(空白对照组)、C组(治疗组)、D组(对照组),每组10只。A组不建模,B、C、D组建立溃疡性结肠炎模型,B组不使用药物,C组使用清热燥湿方保留灌肠,D组使用柳氮磺吡啶灌肠。治疗2周后观察血清TNF-α、IL-1β、IL-4、IL-10水平变化。结果:A组TNF-α、IL-1β均低于B、D组,IL-4、IL-10、Th1/Th2均高于B、D组,差异均有统计学意义(P<0.05),A组上述指标与C组比较差异无统计学意义(P>0.05);C组TNF-α、IL-1β均低于B、D组,IL-4、IL-10、Th1/Th2均高于B、D组,差异均有统计学意义(P<0.05)。结论:清热燥湿方保留灌肠对大肠湿热型溃疡性结肠炎大鼠具有炎症因子调节作用。

Effect of Retention Enema with Qingre Zaoshi Prescription on Th1/Th2 in Rats with Ulcerative Colitis of Damp-heat Type of Large Intestine/ZHENG Fengping,LUO Juli,WANG Aihua.//Chinese and Foreign Medical Research,2019,17(27):-182
【Abstract】 Objective:To explore the effect of retention enema with Qingre Zaoshi Prescription on Th1/Th2 in rats with ulcerative colitis of damp-heat type of large intestine.Method:Forty adult SD rats,SPF grade,weighing 180-200 g,were randomly divided into four groups:group A(normal group),group B(blank control group),group C(treatment group) and group D(control group),with 10 rats in each group.Group A did not model ulcerative colitis.Group B,C and D established ulcerative colitis model.Group B did not use drugs.Group C used retention enema with Qingre Zaoshi Prescription.Group D used sulfasalazine enema with Sulfasalazine.Serum levels of TNF-α,IL-1β,IL-4 and IL-10 were observed after 2 weeks of treatment.Result:The levels of TNF-α and IL-1β in group A were significantly lower than those in groups B and D,IL-4,IL-10 and Th1/Th2 were significantly higher than those in group B and D(P<0.05).There was no significant difference among the above indicators compared with group C(P>0.05).TNF-αand IL-1βin group C were significantly lower than those in group B and D,and IL-4,IL-10 and Th1/Th2 were significantly higher than those in group B and D(P<0.05).Conclusion:Retention enema with Qingre Zaoshi Prescription can regulate inflammatory factors in rats with ulcerative colitis of damp-heat type of large intestine

潰疡性结肠炎作为一种炎性肠病,病变以结直肠黏膜及黏膜下层为主,常表现为腹泻、腹痛、黏液脓血便等。溃疡性结肠炎发病机制不明,但普遍认为免疫功能紊乱是主要致病因素,治疗以调节机体紊乱机制为主[1-2]。中医上认为溃疡性结肠炎归属于“肠擗”“泄泻”范畴,以本虚标实为主要病症,脾胃虚弱或感受外邪,导致出现脾虚兼湿毒之邪内蕴所致[3-4]。有研究表明清热燥湿方对溃疡性结肠炎患者具有显著疗效。但查阅文献发现对于清热燥湿方对溃疡性结肠炎患者的作用机制的报道相对较少,因此本研究通过对SD大鼠建立溃疡性结肠炎模型,探究清热燥湿方保留灌肠对Th1/Th2的影响,具体如下。
