溃疡性结肠炎患者血小板膜糖蛋白Ⅰb/Ⅸ/Ⅴ复合物与疾病严重程度、血小板激活的相关性

目的 探索溃疡性结肠炎(ulcerative colitis,UC)患者血小板膜糖蛋白Ⅰb/Ⅸ/Ⅴ(glycoprotein Ⅰb/Ⅸ/Ⅴ,GP Ⅰb/Ⅸ/Ⅴ)复合物与疾病严重程度、血小板激活的关系.方法 选取了54例活动期UC患者和35名健康志愿者,采用美国胃肠病学会制订的临床指南对活动期UC患者的疾病严重程度进行分级.用比浊法检测UC患者和志愿者血小板最大聚集率(maximum agglutination rate,MAR).采用流式细胞仪检测血小板膜糖蛋白Ⅰb/Ⅸ/Ⅴ复合物、血小板激活标志物血小板α颗粒膜糖蛋白(CD62P)和血小板表面纤维蛋白原受体(PAC-Ⅰ)的水平.结果 活动期UC患者血小板MAR、CD62P和PAC-Ⅰ的阳性表达率较正常对照组明显升高,而GP Ⅰb/Ⅸ/Ⅴ复合物的表达显著降低.在轻、中以及重度活动期UC患者中,血小板MAR、GP Ⅰb/Ⅸ/Ⅴ复合物的表达、CD62P和PAC-Ⅰ的阳性表达率差异具有统计学意义.相关性分析显示血小板GP Ⅰb/Ⅸ/Ⅴ复合物的表达与血小板激活指标MAR、CD62P、PAC-Ⅰ呈负相关.结论 血小板GP Ⅰb/Ⅸ/Ⅴ复合物与血小板激活相关,可能在UC的发展中起作用并反映UC严重程度.

Effect of Wumeiwan on Cytokines TNF-α, IL-6, IL-8, IL-10 and Expression of NF-κBp65 in Rats with Ulcerative Colitis

The effects of Wumeiwan （WMW） on TNF-α, IL-6, IL-8, IL-10 and NF-κBp65 in rats with ulcerative colitis （UC） were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine （SASP） was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley （SD） rats were randomly divided into four groups （n=14 in each group, with equal ratio of male and female）： normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene （DNCB） immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-α, IL-10 and the expression of NF-κBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-α were significantly increased （P〈0.01）, while those of IL-10 significantly reduced （P〈0.01） after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-α were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group （P〈0.05）. The levels of IL-6, IL-8, and TNF-α were lower, while the level oflL-10 was higher in WMW group than in SASP group. NF-κBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-κBp65 in WMW group and SASP group was obviously lower than in model group （P〈0.01）, and there was significant difference between WMW group and SASP group （P〈0.05）. It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-α, IL-6, IL-8, and inhibit the NF-κBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.

β-arrestin1在实验性大鼠结肠炎发生机制中的作用及氧化苦参碱的干预作用

目的研究β-arrestin1在实验性大鼠结肠炎发生机制中的作用,δ阿片受体-β-arrestin1-Bcl-2信号转导通路是否参与实验性大鼠结肠炎的病理过程,氧化苦参碱(OMT)能否通过干预δ阿片受体-β-ar-restin1-Bcl2信号转导通路减轻实验性大鼠结肠炎。方法将26只SD大鼠随机分为4组:分别为正常对照组6只、模型组6只、美沙拉嗪组6只和OMT组8只。正常对照组未行造模,其余3组大鼠均采用三硝基苯磺酸(TNBS)造模。OMT组大鼠给予苦参素注射液肌肉注射,美沙拉嗪组大鼠给予美沙拉嗪混悬液灌胃,模型组和正常组大鼠均以蒸馏水3mL灌胃。治疗15天,观察实验大鼠结肠病理组织学改变,并分别用免疫组化和Western免疫印迹技术分别检测实验大鼠结肠黏膜组织和脾脏T淋巴细胞δ阿片受体、β-arrestin1和Bcl-2表达变化。结果与正常对照组比较,模型组δ阿片受体、β-arrestin1和Bcl-2表达明显增高(P0.01)。与模型组比较,美沙拉嗪组和OMT组δ阿片受体、β-arrestin1、Bcl-2表达均显著下降(P0.01)。结论δ阿片受体-β-arrestin1-Bcl-2信号转导通路参与TNBS诱导的实验性大鼠结肠炎的发病机制;OMT抑制δ阿片受体-β-arrestin1-Bcl-2信号转导通路,是OMT改善TNBS诱导的实验性大鼠结肠炎的机制之一。

Expression of Platelet Membrane Glycoprotein Ib/Ⅸ/Ⅴ Complex,a Receptor of Thrombin,in Patients with Hemorrhagic Thrombopathy

To investigate the role of platelet membrane glycoprotein （GP） Ib/Ⅸ/Ⅴ complex and its subunit GP Ibα in patients with hemorrhagic thrombopathy （HT）, the expressions of GP Ib/Ⅸ/Ⅴ complex and GP Ibα,defined as mean fluorescence intensity （MFI）, were assessed by flow cytometry. The maximum aggregation of platelet was determined by turbidity method. These indicators were compared among 68 HT patients with the presenting complaint of hemorrhage, 33 well-controlled HT patients and 32 normal healthy subjects. The results showed that the MFI of GP Ib/Ⅸ /Ⅴ complex and GP Ibα was markedly lower in HT patients with current hemorrhage than that in the healthy subjects, with difference being statistically significant （P〈0.05）. There was no significant difference in the expressions of GP Ib/ Ⅸ/ Ⅴ complex and GP Ibα between well-controlled HT patients and normal healthy subjects （P〉0.05）. It was concluded that the expression of GP Ib/Ⅸ /Ⅴ complex, the receptor of thrombin and von Willebrand factor, was down-regulated in HT patients with current hemorrhage, which might result in the dysfunction of platelet aggregation and recurrence of HT.
