     【摘要】 目的:通过研究野茼蒿对溃疡性结肠炎大鼠血清相关黏附分子表达的影响,探讨其对溃疡性结肠炎的疗效。方法:选择2,4,6-三硝基苯磺酸(TNBS)与乙醇混合液诱导的溃疡性结肠炎大鼠为研究对象,把UC模型大鼠分为:空白对照组、模型组,野茼蒿低、中、高剂量组,阳性对照组,每组各12只。每天给予各组不同药物处理。于给药21 d后对大鼠结肠组织进行CMDI和HS评分,并用ELISA法检测血清黏附分子CD62P、PSGL-1、CD44、CD54的含量,比较各组间指标差异。结果:与空白组相比,模型组CMDI评分和HS评分以及血清中黏附分子CD62P、PSGL-1、CD44、CD54明显升高(P<0.01或P<0.05);与模型组比较,低、中、高剂量组大鼠上述两个评分以及黏附分子含量一定程度上降低(P<0.01或P<0.05);与模型组相比,SASP组大鼠血清述两个评分以及黏附分子的含量明显降低(P<0.01或P<0.05)。结论:野茼蒿冻干粉对UC大鼠有一定的治疗作用,其机制可能与影响CD62P、PSGL-1、CD44、CD54的表达有关。

    【Abstract】 Objective:To investigate the effect of Wild Chrysanthemum on the expression of serum-related adhesion molecules in rats with ulcerative colitis and to explore its effect on ulcerative colitis.Method:The rats of ulcerative colitis induced by 2,4,6-trinitrobenzene sulfonic acid(TNBS) and ethanol were selected as the study subjects.The UC rats were divided into six groups:blank group,model group,wild chrysanthemum Low,medium and high dose group,positive control group,12 cases in each group.Each group was given a different medication every day.At 21 days after administration,CMDI score and HS score were performed on rat colon tissue.The levels of CD62P,PSGL-1,CD44 and CD54 in serum were measured by ELISA.The differences of six groups were compared and analyzed statistically.Result:Compared with the blank group,the CMDI scores and HS scores and the levels of CD62P,PSGL-1,CD44 and CD54 in the serum of the model group were significantly increased(P<0.01 or P<0.05);compared with the model group,the two scores and the levels of adhesion molecules in serum of the low,medium and high dose rats groups were significantly lower(P<0.01 or P<0.05);compared with the model group,the above two scores and the content of adhesion molecules in serum of SASP group were significantly decreased(P<0.01 or P<0.05).Conclusion:The freeze-dried powder of Wild Chrysanthemum has a certain therapeutic effect on the clinical symptoms of UC rats.The mechanism may be related to the expression of CD62P,PSGL-1,CD44 and CD54.

    潰疡性结肠炎(Ulcerative Colitis,UC)是一种结肠和直肠慢性非特异性炎症性疾病,病因尚不明确,病变范围广泛。目前大多认为其发病机制与免疫因素、遗传因素、心理因素、饮食因素等有关,其中免疫异常被认为是最重要的发病因素。溃疡性结肠炎治愈难度大、病程长,经常反复发作,UC的发病率在我国呈升高的趋势。目前UC临床治疗以激素、水杨酸制剂和免疫抑制剂为主,但疗效欠佳,患者易产生耐药性、过敏等不良反应。中药在治疗UC上具有一定优势,避免了传统西药的弊端,在UC的治疗上显示出了广阔前景,临床上以中药灌肠治疗效果较好[1-2]。野茼蒿(Wild chrysanthemum)是菊科茼蒿属一年或二年生草本植物,在我国境内主要分布于广东、海南、四川、云南等地,是一种常用的药食两用植物,含有多种类型化合物,可治疗慢性肠胃炎[3-5]。黏附分子CD62P、CD44、CD54参与炎症反应中的重要环节,在UC的发病过程中起到了重要作用。本实验用2,4,6-三硝基苯磺酸(TNBS)与乙醇混合液诱导UC大鼠模型,将野茼蒿应用于UC大鼠,通过检测其血清中相关黏附分子的变化水平,以期探讨野茼蒿对UC的治疗机制,为其药用价值提供临床依据,现报道如下。, 百拇医药(彭凡珂 冯陈慧 寇力丹)
