| 1 | Albumin as a prognostic marker for ulcerative colitis显示文摘AIM To evaluate the role of albumin at the time of ulcerative colitis(UC) diagnosis in predicting the clinical course of disease.METHODS Nationwide cohort of patients with newly diagnosed UC in the Veterans Affairs health care system was identified and divided into two categories: hypoalbuminemia(i.e.,≤ 3.5 gm/dl) or normal albumin levels(i.e.,> 3.5 gm/dl) at the time of UC diagnosis. The exposure of interest was presence of hypoalbuminemia defined asalbumin level ≤ 3.5 g/dl at the time of UC diagnosis. Patients were then followed over time to identify the use of ≥ 2 courses of corticosteroids(CS),thiopurines,anti-TNF medications and requirement of colectomy for UC management. RESULTS The eligible study cohort included 802 patients,but 92(11.4%) patients did not have their albumin levels checked at the time of UC diagnosis,and they were excluded. A total of 710 patients,who had albumin levels checked at time of UC diagnosis,were included in our study. Amongst them,536 patients had a normal albumin level and 174 patients had hypoalbuminemia. Patients with hypoalbuminemia at diagnosis had a higher likelihood of ≥ 2 courses of CS use(adjusted HR = 1.7,95%CI: 1.3-2.3),higher likelihood of thiopurine or anti-TNF use(adjusted HR = 1.72,95%CI: 1.23-2.40) than patients with normal albumin level at diagnosis. There was a trend of higher likelihood of colectomy in hypoalbuminemic patients,but it was not statistically significant(Adjusted HR = 1.7,95%CI: 0.90-3.25).CONCLUSION Hypoalbuminemia at disease diagnosis can serve as a prognostic marker to predict the clinical course of UC at the time of diagnosis. | Nabeel Khan Dhruvan Patel Yash Shah Chinmay Trivedi Yu-Xiao Yang | 2017 | World Journal of Gastroenterology2017，23，45： | 6 |
| 2 | 复方血竭对结肠炎模型大鼠Toll样受体4/核因子κB及树突状细胞表型的影响(英文)显示文摘背景:树突状细胞可调节肠道内环境的免疫反应,这一功能缺陷会导致炎症性肠病,Toll样受体4/核因子κB通路与上述反应密切相关。目的:构建实验性结肠炎模型大鼠,观察复方血竭对其树突状细胞及Toll样受体4/核因子κB表达的影响并探讨其作用机制。方法:将大鼠随机抽样法分为空白对照组、模型组、复方血竭组和5-氨基水杨酸治疗组。除空白对照组外,其他3组大鼠建立2,4,6-三硝基苯磺酸诱导的实验性结肠炎模型。造模成功后,复方血竭组和5-氨基水杨酸治疗组分别给予复方血竭[0.75 g/(kg·d)]和5-氨基水杨酸[(100 mg/(kg·d)]灌胃治疗10 d。结果与结论:复方血竭组较模型组大鼠的疾病活动指数评分、大体形态损伤评分、病理组织学评分均显著降低(P<0.05),5-氨基水杨酸治疗组、复方血竭组的症状、结肠组织损害均较模型组明显减轻。模型组大鼠肠系膜淋巴结CD80和CD86的表达率,Toll样受体4,核因子κB表达较其他3组均显著升高(P<0.05或P<0.01)。复方血竭组Toll样受体4及核因子κB表达明显低于5-氨基水杨酸治疗组。结果证实,复方血竭可部分缓解实验性结肠炎模型大鼠的症状,有效抑制其肠系膜淋巴结中树突状细胞的活化。复方血竭可能通过抑制大鼠肠黏膜细胞Toll样受体4和核因子κB的表达而缓解肠道的炎症反应。 | 李楠 王雪明 稽杨 石玉玲 王欣 李娜 苏丽 沙丽娜 | 2015 | 中国组织工程研究2015，19，5： | 4 |
