5mi R-122 negatively correlates with liver fibrosis as detected by histology and FibroScan显示文摘AIM: To investigate whether expression of selected mi RNAs obtained from fibrotic liver biopsies correlate with fibrosis stage.METHODS: Altogether, 52 patients were enrolled in the study representing various etiologic backgrounds of fibrosis: 24 cases with chronic hepatitis infections(types B, C), 19 with autoimmune liver diseases(autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis, overlapping syndrome cases), and 9 of mixed etiology(alcoholic and nonalcoholic steatosis, cryptogenic cases). Severity of fibrosis was determined by both histologic staging using the METAVIR scoring system and noninvasive transient elastography. Following RNAisolation, expression levels of mi R-21, mi R-122, mi R-214, mi R-221, mi R-222, and mi R-224 were determined using Taq Man Micro RNA Assays applying mi R-140 as the reference. Selection of mi RNAs was based on their characteristic up- or downregulation observed in hepatocellular carcinoma. Relative expression of mi RNAs was correlated with fibrosis stage and liver stiffness(LS) value measured by transient elastography, as well as with serum alanine aminotransferase(ALT) level.RESULTS: The expression of individual mi RNAs showed deregulated patterns in stages F1-F4 as compared with stage F0, but only the reduced level of mi R-122 in stage F4 was statistically significant(P < 0.04). When analyzing mi RNA expression in relation to fibrosis, levels of mi R-122 and mi R-221 showed negative correlations with fibrosis stage, and mi R-122 was found to correlate negatively and mi R-224 positively with LS values(all P < 0.05). ALT levels displayed a positive correlation with mi R-21(P < 0.04). Negative correlations were observed in the fibrosis samples of mixed etiology between mi R-122 and fibrosis stage and LS values(P < 0.05), and in the samples of chronic viral hepatitis, between mi R-221 and fibrosis stage(P < 0.01), whereas mi R-21 showed positive correlation with ALT values in the samples of autoimmune liver diseases(P < 0.03). The results also revealed a strong correlation between fibrosis stage and LS values(P < 0.01) when etiology of fibrosis was not taken into account.CONCLUSION: Reduced expression of mi R-122 in advanced fibrosis and its correlation with fibrosis stage and LS values seem to be characteristic of hepatic fibrosis of various etiologies.Tünde Halász Gábor Horváth Gabriella Pár Klára Werling András Kiss Zsuzsa Schaff Gábor Lendvai 2015World Journal of Gastroenterology2015,21,25:11

7Frequency of infarct-related artery with myocardial bridging in patients with ST-elevation myocardial infarction and its impact upon percutaneous coronary intervention显示文摘Background Myocardial bridging (MB) as a congenital condition with a reported frequency of 5%-12% in diagnostic coronary angiography may be an important factor causing myocardial ischemia. However, its frequency in the infarct-related artery (IRA) of patients with ST-elevation myocardial infarction (STEMI) and the impact upon percutaneous coronary intervention (PCI) remain undetermined. In this study, we investigated MB frequency and its impact upon primary PCI in patients with STEMI. Methods The data of coronary angiography for 554 consecutive patients with STEMI who had undergone successful primary PCI were retrospectively analyzed to identify a frequency of MB in the IRA and its association with gender and age. According to the angiographic findings, the patients were divided into MB patients and non-MB patients. The endpoints of this study included immediate angiographic findings after primary PCI and 6-month major adverse cardiac events (MACE) (death, recurrent myocardial infarction, target lesion or vessel revascularization) between the MB patients and the non-MB patients. Results A frequency of MB in the IRA of 46 patients (8.3%) was identified in this series; it was more common in patients ≥65 years old (36/206) than in those <65 years old (10/348) (17.5% vs 2.9%, P<0.001). The trend of MB in the IRA was observed more frequently in women without significant difference than in men (10.2% vs 7.8%). TIMI grade III flow was achieved in 91.9% (509/554) of all patients following primary PCI, in 60.9% (28/46) of the MB patients and in 94.7% (481/508) of the non-MB patients respectively (P<0.001). The in-hospital mortality was 4.7% (26/554) in this series including 13.0% (6/46) of the MB patients and 3.9% (20/508) of the non-MB patients (P<0.001). A significant difference in 6 months MACE was seen between the MB patients (19%) and the non-MB patients (6.2%) (P<0.001). Conclusions MB in the IRA is relatively common in elderly patients with STEMI with a more evident trend in women, suggesting that arteriosclerosis and plaque rupture occurs more easily in the proximal artery to MB than in younger patients. Poor TIMI grade flow in patients with MB in the IRA after primary PCI may contribute to a high in-hospital mortality rate (13%) and 6-month MACE (19%) in the MB patients.YAN Hong-bing WANG Jian ZHU Xiao-ling GAO Hal LI Nan AI Hui 2006Chinese Medical Journal2006,,7:9
8资源型城市财源建设的风险识别与制度优化路径--以陕西省延安市为例显示文摘1994年财税体制改革促成了此后延续至今的改革红利,但其财政分权的改革远未到位,近年来能源富集区经济发展中遇到的地方税收体系建设滞后、地方政府财政困难、提供基本公共服务能力弱等问题均与此密切相关。今后所实施新一轮改革中,财税体制改革是全面深化经济体制改革的核心之一,应重点解决资源富集区矿产资源开发收益没有得到合理分配对地方政府财源建设所带来的风险。本文以陕西省延安市为例,认真分析财源结构、三次产业税收收入、税收收入与非税收收入的状况,以及省市分税的影响,深入研究现行财政分权影响地方财源建设的四大风险:税收与税源分离的风险、三次产业税源结构调整的风险、财政收支缺口的风险和税制改革滞后所引发的潜在风险,并深入剖析问题根源,积极探索优化资源型城市财源建设的制度路径。宋敏 刘学敏 Hal T.Nelson 2016中国软科学2016,,10:7
9触摸屏设计日益简化 投射式电容触摸屏前景广阔显示文摘现今社会上很多人都频繁地接触到触摸屏。这种装置最常见于PDA和手机等手持设备和售票终端系统等应用,其中大部分都基于电阻性技术。电阻性技术采用一个柔性外层,其压触固定内层时,会产生电信号,然后转换为x—Y坐标位置。此外,还有其它两种常用技术:表面声波(SAW)和电容感测技术,不过,一直以来,由于成本和构建的限制,这两种技术都仅用在公用信息服务应用(Kioskapplications)中。Hal Philipp 2009中国电子商情2009,,9:5

11Deep Brain Stimulation──A new treatment for tinnitus显示文摘Intractable tinnitus can lead to serious consequences. Study evidence indicates that the central nervous system is involved in generation and maintenance of chronic tinnitus and that tinnitus and other neurologic symptoms such as chronic pain may share similar mechanisms. Brain ablation and stimulation are used to treat chronic pain with success. Recent studies showed that ablation and stimulation in non-auditory areas resulted in tinnitus improvement. Deep brain stimulation (DBS) may be an alternative treatment for intractable tinnitus and deserves further study.William Hal Martin 2007Journal of Otology2007,2,1:4
12Full scale experimental study of a small natural draft dry cooling tower for concentrating solar thermal power plant显示文摘Concentrating solar thermal power system can provide low carbon,renewable energy resources in countries or regions with strong solar irradiation.For this kind of power plant which is likely to be located in the arid area,natural draft dry cooling tower is a promising choice.To develop the experimental studies on small cooling tower,a 20 m high natural draft dry cooling tower with fully instrumented measurement system was established by the Queensland Geothermal Energy Centre of Excellence.The performance of this cooling tower was measured with the constant heat input of 600 kW and 840 kW and with ambient temperature ranging from 20 ℃ to 32 ℃.The cooling tower numerical model was refined and validated with the experimental data.The model of 1 MW concentrating solar thermal supercritical CO2 power cycle was developed and integrated with the cooling tower model.The influences of changing ambient temperature and the performance of the cooling tower on efficiency of the power system were simulated.The differences of the mechanism of the ambient temperature effect on Rankine cycle and supercritical CO2 Brayton cycle were analysed and discussed.Xiaoxiao Li Sam Duniam Hal Gurgenci Zhiqiang Guan Anand Veeraragavan 侯恩哲 2017建筑节能2017,45,5:4
