5Intervention to increase physical activity in irritable bowel syndrome shows long-term positive effects显示文摘AIM: To assess the long-term effects of physical activity on irritable bowel syndrome(IBS) symptoms and on quality of life, fatigue, depression and anxiety.METHODS: Seventy-six patients from a previous randomized controlled interventional study on increased physical activity in IBS were asked to participate in this long-term follow-up study. The included patients attended one visit in which they filled out questionnaires and they underwent a submaximal cycle ergometer test. The primary end point was the change in the IBS Severity Scoring System(IBS-SSS) at baseline, i.e., before the intervention and at follow-up. The secondary endpoints were changes in quality of life, fatigue, depression and anxiety.RESULTS: A total of 39 [32 women, median age 45(28-61) years] patients were included in this followup. Median follow-up time was 5.2(range: 3.8-6.2) years. The IBS symptoms were improved compared with baseline [IBS-SSS: 276(169-360) vs 218(82-328), P = 0.001]. This was also true for the majority of the dimensions of psychological symptoms such as disease specific quality of life, fatigue, depression and anxiety. The reported time of physical activity during the week before the visit had increased from 3.2(0.0-10.0) h at baseline to 5.2(0.0-15.0) h at follow-up, P = 0.019. The most common activities reported were walking, aerobics and cycling. There was no significant difference in the oxygen uptake 31.8(19.7-45.8) m L per min per kg at baseline vs 34.6(19.0-54.6) m L/min per kg at follow-up.CONCLUSION: An intervention to increase physical activity has positive long-term effects on IBS symptoms and psychological symptoms.Elisabet Johannesson Gisela Ringstrom Hasse Abrahamsson Riadh Sadik 2015World Journal of Gastroenterology2015,21,2:6
6南极冬季威德尔海冰脊的表面形态显示文摘基于2006年南极威德尔海冬季科学考察期间由机载激光测高仪测得的海冰上表面高度数据,以脊高和脊距的理论与实测概率密度的相对误差之和为性能指标,以切断高度为控制变量建立优化模型。结果表明,W'80型分布和对数正态分布分别与实测脊高和脊距分布吻合较好;最优切断高度为0.62 m。进而从海冰表面起伏中确定出冰脊。利用k均值聚类算法以冰脊强度(Ri)为标准将剖面分为3类(Ri≤0.01,0.010.026)。对应各类剖面分别有:平均脊高为0.99 m,1.12 m和1.17 m;平均脊距为232 m,54 m和31 m。利用数学模型估算并分析了多脊冰平均厚度、有效厚度,帆横截面积及冰脊所占面积,这些参数值均随冰脊强度增大而增大。谭冰 李志军 卢鹏 HASS Christian NICOLAUS Marcel 2012水科学进展2012,23,1:5
7急性心肌梗死桥血管病变急诊介入治疗的临床研究显示文摘目的评价梗死相关血管为静脉桥血管(SVBG)的急性心肌梗死(AMI)患者,进行急诊直接经皮冠状动脉介入治疗(PCI)的有效性及安全性。方法对≥70岁(213例)与<70岁(96例)两组AMI患者介入治疗的临床效果和不良事件进行比较。分析SVBG有效再通比例、住院期间死亡比例及短期临床预后。结果两组患者PCI的技术成功比例、急性再闭塞比例均未见显著差异。但在≥70岁组,PCI后发生慢血流和无血流现象明显为多、住院期间绝对死亡数为多(20vs4)。死亡病例分析显示,90%的死亡病例出现在发生慢血流无血流现象的病例;多次心肌梗死、SVBG连通优势冠状动脉血管、以及连通惟一剩存的SVBG时,发生无血流慢血流后,死亡危险较高。结论老年AMI患者的SVBG病变急诊介入治疗有明确的效果和高的技术成功率。王禹 Hasse KK 盖鲁粤 杨庭树 沈洪 计达 陈练 孙志军 任艺红 2005中华老年心脑血管病杂志2005,7,3:4
8Identification of osteopontin as the most consistently over-expressed gene in intrahepatic cholangiocarcinoma: Detection by oligonucleotide microarray and real-time PCR analysis显示文摘AIM: To investigate the molecular pathways involved in human cholangiocarcinogenesis by gene expression profiling. METHODS: Oligonucleotide arrays (Affymetrix U133A) were used to establish a specific gene expression profile of intrahepatic CCC in comparison to corresponding non- malignant liver tissue. To validate the expression values of the most overexpressed genes, RT-PCR experiments were performed. RESULTS: Five hundred and fifty-two statistically differentially expressed genes/ESTs (221 probes significantly up-regulated, 331 probes down-regulated; P < 0.05; fold change > 2; ≥ 70%) were identified. Using these data and two-dimensional cluster analysis,a specific gene expression profile was obtained allowing fast and reproducible differentiation of CCC, which was confirmed by supervised neuronal network modelling. The most consistently overexpressed gene (median fold change 33.5, significantly overexpressed in 100%) encoded osteopontin. Furthermore, an association of various genes with the histopathological grading could be demonstrated. CONCLUSION: A highly specific gene expression profile for intrahepatic CCC was identified, allowing for its fast and reproducible discrimination against non- malignant liver tissue and other liver masses. The most overexpressed gene in intrahepatic CCC was the gene encoding osteopontin. These data may lead to a better understanding of human cholangiocarcinogenesis.Holger G Hass Oliver Nehls Juergen Jobst Andrea Frilling Ulrich Vogel Stephan Kaiser 2008World Journal of Gastroenterology2008,14,16:4
