BACKGROUND： Continuous regional arterial infusion（CRAI） is a drug delivery system, which dramatically increases the drug concentration in the pancreas. Previous clinical and basic studies have demonstrated the possible therapeutic efficacy of CRAI for severe acute pancreatitis（SAP）. This meta-analysis of all published randomized controlled trials（RCTs） was conducted to assess the efficacy and safety of CRAI for the treatment of SAP. DATA SOURCES： Up to August 10, 2014, RCTs comparing CRAI with intravenous infusion for SAP in PubM ed, Embase, EBSCO, MEDLINE, Science Citation Index Expanded, Cochrane Library, China Academic Journals Full-Text Database, Chinese Biomedical Literature Database, and Chinese Scientific Journals Database were selected by two independent reviewers. The relative risk（RR） and their 95% confidence intervals（CI） for duration of elevated serum amylase and urine amylase, duration of abdominal pain, infection rate, incidence of complication, overall mortality, curative rate, hospital stay and details of subgroup analysis were extracted. Meta-analyses were made using the software Review Manager（RevM an version 5.10）.RESULTS： Six RCTs with 390 patients meeting the inclusion criteria were included in the final analysis. Compared with intravenous infusion route, CRAI significantly shortened the duration of elevated urine amylase（MD=-2.40, 95% CI=-3.20,-1.60; P〈0.00001） and the duration of abdominal pain（MD=-1.46, 95% CI=-1.94,-0.98; P〈0.00001）, decreased the incidence of complication（RR=0.35, 95% CI=0.15, 0.81; P=0.01） and overall mortality（RR=0.25, 95% CI=0.08, 0.78;P=0.02）, shortened the duration of hospital stay（MD=-10.36, 95% CI=-17.05,-3.68; P=0.002）, and increased the curative rate（RR=1.66, 95% CI=1.13, 2.46; P=0.01）. No mortality and catheter-related infections due to CRAI administration was reported in these studies. Subgroup analysis showed that the combination of drug administration via CRAI did not significantly improve the ***

Nonlinear quantum interferometry with Bose condensed atoms

作者： Chaohong Lee (1) Jiahao Huang (1) Haiming deng (1) hui Dai (1) Jun Xu (1) 1. State Key Laboratory of Optoelectronic Materials and Technologies School of Physics and Engineering Sun Yat-Sen University Guangzhou 510275 China

In quantum interferometry, it is vital to control and utilize nonlinear interactions for the achievement of high-precision measurements. Due to their long coherence time and high controllability, ultracold atoms including Bose condensed atoms have been widely used for quantum interferometry. Here, we review recent progress in theoretical studies of quantum interferometry with Bose condensed atoms. In particular, we focus on nonlinear phenomena induced by atom-atom interactions, and how to control and utilize these nonlinear phenomena. With a mean-field description, due to atom-atom interactions, matter-wave solitons appear in the interference patterns, and macroscopic quantum self-trapping exists in Bose-Josephson junctions. With a many-body description, atom-atom in- teractions can generate non-classical entanglement, which can be utilized to achieve high-precision measurements beyond the standard quantum limit.

Evolution of isolated G-band bright points: size, intensity and velocity

引用

Research in Astronomy and Astrophysics 2014年第6期14卷 741-752页

We study the evolution pattern of isolated G-band bright points （GBPs） in terms of their size, intensity and velocity. Using a high resolution image sequence taken with the Hinode/Solar Optical Telescope （SOT）, we detect GBPs in each image by the Laplacian and Morphological Dilation algorithm, and track their evolutions by a 26-adjacent method in a three-dimensional space-time cube. For quantifying the evolution, we propose a quantification method based on lifetime normalization which aligns the different lifetimes to common stages. The quantification results show that, on average, the diameter of isolated GBPs changes from 166 to 173 km, then down to 165 km; the maximum intensity contrast changes from 1.012 to 1.027, then down to 1.011; however, the velocity changes from 1.709 to 1.593 km s-1, then up to 1.703 km s-i. The results indicate that the evolution follows a pattern such that the GBP is small, faint and fast-moving at the birth stage, becomes big, bright and slow-moving at the middle stage, then gets small, faint and fast-moving at the decay stage until disappearance. Although the differences are very small, a two-sample t-test is used to demonstrate there are significant differences in means between the distri- butions of the different stages. Furthermore, we quantify the relationship between the lifetimes of GBPs and their properties. It is found that there are positive correlations between the lifetimes and their sizes and intensities with correlation coefficients of 0.83 and 0.65, respectively; however, there is a negative correlation between the life- times and velocities with a correlation coefficient of-0.49. In summary, the longer the GBP persists, the bigger, brighter and slower it will be.

NUMERICAL SIMULATION OF LEVEE BREACH FLOWS UNDER COMPLEX BOUNDARY CONDITIONS

引用

Journal of Hydrodynamics 2009年第5期21卷 633-639页

作者： YU Ming-hui deng Yin-ling QIN Lian-chao WANG Dang-wei CHEN Ya-ling State Key Laboratory of Water Resources and Hydropower Engineering Science Wuhan University Wuhan 430072 China

Levee or dam failure can cause a significant disaster in most cases. A good prediction of the flood process especially in a real complex terrain is necessary for working out emergency plans for levee or dam breaches. Numerical simulations of levee or dam breach flow were carried out often with constant flow parameters and in relatively simple channels rather than in natural rivers with complex boundaries. This article presents our dedicated studies on the 2-D numerical model of levee or dam breach hydraulics with finite difference schemes. The good performance of the model is demonstrated by comparisons with the theoretical solution of an idealized dam-break flow over a frictionless flat rectangular channel. The model is also validated through its stability and conservation properties. The model is applied to simulate the flood propagation under complex boundary conditions, and the unsteady flood process in a river and in the dry floodplain with a complex bed terrain simultaneously. Furthermore, with respect to engineering practice, the numerical solutions can give special guidance to the effects of parameters such as the flood depth at different sites and the inundated area at different time periods after the levee breach and the travel time of the flood waves, which may be very important for practicing engineers in an efficient flood management.
