1Accuracy of urea breath test in Helicobacter pylori infection: Meta-analysis显示文摘AIM: To quantitatively summarize and appraise the available evidence of urea breath test(UBT) use to diagnose Helicobacter pylori(H. pylori) infection in patients with dyspepsia and provide pooled diagnostic accuracy measures.METHODS: We searched MEDLINE, EMBASE, Cochrane library and other databases for studies addressing the value of UBT in the diagnosis of H. pylori infection. We included cross-sectional studies that evaluated the diagnostic accuracy of UBT in adult patients with dyspeptic symptoms. Risk of bias was assessed using QUADAS(Quality Assessment of Diagnostic Accuracy Studies)-2 tool. Diagnostic accuracy measures were pooled using the random-effects model. Subgroup analysis was conducted by UBT type(13C vs 14C) and by measurement technique(Infrared spectrometry vs Isotope Ratio Mass Spectrometry).RESULTS: Out of 1380 studies identified, only 23 met the eligibility criteria. Fourteen studies(61%) evaluated 13 C UBT and 9 studies(39%) evaluated 14 C UBT. There was significant variation in the type of reference standard tests used across studies.Pooled sensitivity was 0.96(95%CI: 0.95-0.97) andpooled specificity was 0.93(95%CI: 0.91-0.94). Likelihood ratio for a positive test was 12 and for a negative test was 0.05 with an area under thecurve of 0.985. Meta-analyses were associated with a significant statistical heterogeneity that remained unexplained after subgroup analysis. The included studies had a moderate risk of bias.CONCLUSION: UBT has high diagnostic accuracy for detecting H. pylori infection in patients with dyspepsia. The reliability of diagnostic meta-analytic estimates however is limited by significant heterogeneity.Mazen Ferwana Imad Abdulmajeed Ali Alhajiahmed Wedad Madani Belal Firwana Rim Hasan Osama Altayar Paul J Limburg Mohammad Hassan Murad Bandar Knawy 2015World Journal of Gastroenterology2015,21,4:45
2埃及尼罗河三角洲城市化监测显示文摘对1972、1984和1990年在尼罗河三角洲获取的Landsat MSS和TM影象(scenes)处理的和协同配准的(coregistered)数字镶嵌图比较表明,城镇增长正危及着埃及农业的生产力。在1972、1984和1990年尼罗河三角洲的城镇面积至少分别占3.6%、4.7%和5.7%,在这18年期间增长了58%。大约一半的增长出现在1984~1990年期间。如果这种趋势继续下去,到2010年埃及将因城市化而丧失农地总面积的12%。尽管事实上城镇增长主要出现在城市周围,但在几千个小村庄周围的增长却对尼罗河三角洲的农业生产构成最大的威胁。1972~1990年间,城市和大村庄的累积增长率为37%,而同期小村庄的累积增长率为77%。Mohamed Sultan Michael Fiske Thomas Stein Mohamed Gamal Yehia Abdel Hady Hesham El Araby Ahmed Madani Salah Mehanee Richard Becker 石培礼 1999AMBIO-人类环境杂志1999,28,7:9
3基于Adams和Matlab联合仿真的双足机器人越障研究显示文摘与轮行机器人相比,双足机器人具有更灵活的机械结构,具有跨越静态或动态障碍物的能力,使其可以在更复杂的环境中工作;以往的双足机器人路径规划控制策略只能解决静止或以可预测速度运动的障碍物的越障问题,提出了一种基于模糊Q学习算法的路径规划策略,在Adams软件中建立机器人的三维虚拟样机模型,在Matlab软件中设计控制器,进行联合仿真;仿真结果表明所设计的控制策略可以有效地克服机器人在线学习时间长的问题,并且可以成功跨越速度不可预测的运动障碍物,有很好的鲁棒性。于薇薇 C.

4不同气蚀次数球阀空化的数值研究(英文)显示文摘空化是控制阀中的一种破坏性现象。为了延缓空化,采用一种多孔圆柱板,称为trim。在此之前,我们曾研究过孔板直径和不同类型的trim的影响。本文采用4种不同工况(无trim,1,2和3 trims)对球阀进行数值分析,分析了trim的数量对气蚀强度、形成区域和空化起始点的影响。结果表明,与不加trim的阀门相比,增加一个或两个trim可以降低气蚀的强度,延缓空化的发生。然而,在使用两到三个trims的情况下,空化的强度和起始点没有明显的差异。由于trim生产成本高,流量系数严重下降,将trim数量增加到3个以上在经济和技术上都是不合理的。Hamidreza YAGHOUBI Seyed Amir Hossein MADANI Mansour ALIZADEH 2018Journal of Central South University2018,25,11:6
5施用有机氮肥条件下地下排水中硝态氮流失的模拟研究显示文摘将改进的有机氮肥管理模型(MANIMEA)与广为应用的土壤水流运动模型(SWAP)相耦合,用于模拟评价施用猪粪条件下NO3--N(硝态氮)通过地下排水的流失量。采用加拿大新斯科舍省农业大学试验站4个试验地块1999年的日地下排水量及NO3--N流失量观测值对模型进行了模拟验证。模拟结果表明,预测的日地下排水量与观测的地下排水量吻合较好,相关系数在0.73~0.78之间;日NO3--N流失量与地下排水量的关系密切,4个试验地块NO3--N流失量模拟值与观测值平均误差在-0.017kg/hm2和0.005 kg/hm2之间,绝对平均误差范围在0.087 kg/hm2和0.152 kg/hm2之间。模拟时段NO3--N总流失量与观测值的相对误差在-0.5%和8.9%之间。总体来说,图形显示和统计指标分析表明,MANIMEA模型具有良好的模拟性能,模型能够较好的预测地下排水中NO3--N流失量。王少丽 许迪 S.O.Prasher Ali Madani 2006水利学报2006,37,1:6
6肺动脉内膜剥脱术治疗慢性栓塞性肺动脉高压——UCSD32例手术经验显示文摘目的 分析肺动脉内膜剥脱术(PEA)治疗慢性栓塞性肺动脉高压的围手术期资料,探讨美国加州大学圣迭戈分校(UCSD)手术经验.方法 回顾性研究UCSD 32例肺动脉血栓内膜剥脱手术资料,其中男17例,女15例;平均年龄(47.56±16.04)岁,平均病程(3.90±4.61)年;15例有深静脉血栓病史.采用全麻、胸骨正中切口、深低温、间断停循环双侧肺动脉内膜剥脱的手术方法.结果 根据术中病理标本Jamieson分型,Ⅰ型占21.8%,Ⅱ型占28.1%,Ⅲ型占37.5%.平均转机(236.32±37.27)min,主动脉阻断(111.69±28.14)min,停循环(38.00±13.58)min.术后机械通气(66.23±99.24)h,住ICU(4.62±4.50)天,无死亡.病人肺动脉收缩压由术前(81.03±16.92)mm Hg(1 mm Hg=0.133 kPa)降至术后(51.20±12.16)mm Hg,肺血管阻力由术前(88.91±42.32)kPa·s·L-1降至术后的(34.38±15.68)kPa·s·L-1,心排量由术前(3.65±1.08)L/min增加到术后(5.85±1.21)L/min,中心静脉压由(13.07±2.11)cmH2O(1 cmH2O=0.098 kPa)降至(9.86±3.02)cmH2O.术后短期随访显示,病人心功能(NYHA)恢复到Ⅰ级19例、Ⅱ级13例,生活质量明显改善.结论 PEA是治疗慢性栓塞性肺动脉高压的重要手段,手术成功率逐年提高;深低温、间断停循环、双侧肺动脉内膜剥脱及内膜外翻技术为PEA标准术式.多中心资料证实该术式可以有效降低肺动脉压和肺血管阻力,明显改善血流动力学指标和心肺功能.多数国内医疗中心没有足够手术经验,应尽量避免选择肺动脉压收缩≥100mmHg,肺血管阻力≥100kPa·s·L^-1及Ⅲ型病变者行PEA手术.顾松 刘岩 苏丕雄 翟振国 杨媛华 王辰 Michael M.

7Surface Treatment of Inorganic CsPbI_(3) Nanocrystals with Guanidinium Iodide for Efficient Perovskite Light-Emitting Diodes with High Brightness显示文摘The remarkable evolution of metal halide perovskites in the past decade makes them promise for next-generation optoelectronic material.In particular,nanocrystals(NCs)of inorganic perovskites have demonstrated excellent performance for light-emitting and display applications.However,the presence of surface defects on the NCs negatively impacts their performance in devices.Herein,we report a compatible facial post-treatment of CsPbI_(3) nanocrystals using guanidinium iodide(GuI).It is found that the GuI treatment effectively passivated the halide vacancy defects on the surface of the NCs while offering effective surface protection and exciton confinement thanks to the beneficial contribution of iodide and guanidinium cation.As a consequence,the film of treated CsPbI_(3) nanocrystals exhibited significantly enhanced luminescence and charge transport properties,leading to high-performance light-emitting diode with maximum external quantum efficiency of 13.8%with high brightness(peak luminance of 7039 cd m^(−2) and a peak current density of 10.8 cd A^(−1)).The EQE is over threefold higher than performance of untreated device(EQE:3.8%).The operational half-lifetime of the treated devices also was significantly improved with T50 of 20 min(at current density of 25 mA cm^(−2)),outperforming the untreated devices(T50~6 min).Minh Tam Hoang Amandeep Singh Pannu Yang Yang Sepideh Madani Paul Shaw Prashant Sonar Tuquabo Tesfamichael Hongxia Wang 2022Nano-Micro Letters2022,14,4:2
