2新加坡成人慢性呼吸系统疾病患者6分钟步行距离的最小临床重要差异值研究(英文)显示文摘目的:6 min步行距离(6MWD)是临床上常见的功能性运动能力测试,特别是对于慢性呼吸系统疾病患者。一些文献记载了关于白种人的6MWD的最小临床重要差异(MCID),但对亚洲人群的相关信息未见记载。本研究旨在建立亚洲成人慢性呼吸道疾病患者6MWD的最小临床重要差异。方法:采用'锚定'法和'分布'法对新加坡中央医院肺康复计划登记处的资料进行了分析。'锚定'法收集确诊为慢性呼吸道疾病的患者50例,其中男38例,女12例;平均年龄(64.2±12.3)岁,通过电话采访及使用整体变化评估量表(GROC)评价患者肺康复计划后的自觉改善程度,再将患者在肺康复计划中6MWD的改变数值与相对应的患者自觉改善程度进行比较,这种关系用操作特征曲线(ROC)统计表示。通过'分布'法确定6MWD的MCID,从门诊和住院的肺康复计划(PRP)参与者中检索医疗记录136例,其中男103例,女33例;平均年龄(60.1±14.1)岁。结果 :ROC曲线表明6MWD出现临床显著性变化的最佳临界值为17.4 m,其对应的敏感性为79.4%,特异性为81.3%,阳性似然比为4.23。由'分布'法确定6MWD的最小临床重要差异值为18.6 m。结论:18.6 m为新加坡华人6MWD的最小临床重要差异的估计值。Meredith T L YEUNG Alan W P WONG Katherine S L HUANG Alice Y M JONES 2015康复学报2015,25,1:3
3Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3
