Purpose:To compare the effects and side-effects of fondaparinux sodium and low molecular weight heparin in patients with hypercoagulability accompanied with traumatic infection.Methods:Thirty-six patients with post-traumatic infections in our hospital intensive care center were diagnosed with hypercoagulability from February 2012 to February 2013. These patients were randomly divided into 2 groups. In group F (18 patients), the patients were treated with fondaparinux sodium, 2.5 mg, 1/d for 11 d. In group L (18 patients), the patients were treated with low molecular weight heparin, 4100 U, 1/12 h for 11 d. The incidence of deep vein thrombosis, bleeding events and multiple organ dysfunction syndrome (MODS) and mortality of two groups after anticoagulation therapy were analyzed. Fibrinogen, D-dimer level and activity of antithrombin III were measured by the coagulation analyzer.Results:The incidence of deep vein thrombosis, MODS incidence and mortality were not significantly different between the two groups. The rate of bleeding evens in group F was lower than group L ( p 0.05). D-dimer was significantly decreased after anticoagulant therapy for 5 d ( p 0.05). Conclusion:Fondaparinux sodium and low molecular weight heparin can effectively improve coagulopathy in patients with traumatic infection. Compared with low molecular weight heparin, fondaparinux sodium may reduce the risk of bleeding events in patients with hypercoagulability accompanied by traumatic infection.

针对潜水探摸费用高、作业时间受限,传统光栅监测不直观及多波束测深监测在实时性连续性上存在缺陷,采用定点静态监测方法,将两台双轴扫描声呐设备固定安装在指定桥墩上,声呐探头以一定的水平角度和垂直角度步进旋转,在水平、垂直旋转指定角度区间形成一幅完整的三维点云图像。采集的数据由串口服务器转为网络数据后通过4G DTU远程传输给数据接收终端进行处理、汇总、分析、成图、显示。通过软硬件集成系统实现大范围、长时间、高频次、高精度的无人值守冲刷监测,避免了探头中途拆装等操作对前后所测数据的一致性产生的可能影响。同时,固定安装的声呐系统克服了其他监测手段数据不直观、不及时等缺陷,可按照指定时间获取面状的全覆盖海底地形数据,对桥墩周边海床基础数据进行实时冲刷监测,监测系统运行稳定,远程采集控制及回传数据正常,数据精度可达0.1 m,数据点密度可达1 m×1 m。数学模型对冲刷坑的冲刷深度和范围与实测值相比,结果吻合。

Objective:To discuss the characteristics and risk factors for intracranial infection post traumatic brain injury to prevent and better the clinical care.Methods:Retrospective study of 520 patients with traumatic brain injury were included, 308 male and 212 female. The risky factors of intracranial infection were identified.Results:Thirty two cases (6.54%, 32/520) of intracranial infection were diagnosed. Intracranial infection most likely happened 4-10 days after injury. Cerebrospinal fluid leakage, drainage, multiple craniotomies were significant related to intracranial infection. Logistic regression predicted cerebrospinal fluid leakage and drainage as independent factors.Conclusion:Intracranial infection is a serious complication after traumatic brain injury. Patients with drainage or cerebrospinal fluid leakage are more risky for intracranial infection. Aggressive precaution should be taken to better outcome.

As promising anode candidates for potassium-ion batteries(PIBs),antimony sulfide(Sb_(2)S_(3))possesses high specific capacity but suffers from massive volume expansion and sluggish kinetics due to the large K^(+)insertion,resulting in inferior cycling and rate performance.To address these challenges,a yolk-shell structured Sb_(2)S_(3)confined in N,S co-doped hollow carbon nanorod(YS-Sb_(2)S_(3)@NSC)working as a viable anode for PIBs is proposed.As directly verified by in situ transmission electron microscopy(TEM),the buffer space between the Sb_(2)S_(3)core and thin carbon shell can effectively accommodate the large expansion stress of Sb_(2)S_(3)without cracking the shell and the carbon shell can accelerate electron transport and K^(+)diffusion,which plays a significant role in reinforcing the structural stability and facilitating charge transfer.As a result,the YS-Sb_(2)S_(3)@NSC electrode delivers a high reversible K^(+)storage capacity of 594.58 m A h g^(-1)at 0.1 A g^(-1)and a long cycle life with a slight capacity degradation(0.01%per cycle)for 2000 cycles at 1 A g^(-1)while maintaining outstanding rate capability.Importantly,utilizing in in situ/ex situ microscopic and spectroscopic characterizations,the origins of performance enhancement and K^(+)storage mechanism of Sb_(2)S_(3)were clearly elucidated.This work provides valuable insights into the rational design of high-performance and durable transition metal sulfides-based anodes for PIBs.

嵌套高分辨率网格对台风模拟有十分重要的影响。基于COAWST(coupled ocean atmosphere wave sediment transport)模式,针对登陆广东、海南的11个台风,设计了2组模拟方案。一组是在9 km分辨率下嵌套3 km分辨率网格,另一组是采用单层9 km分辨率网格。将模拟结果与中国气象局热带气旋资料中心发布的最佳路径数据进行对比,以探讨嵌套高分辨率网格是否可以提高台风模拟的准确性。从台风路径的模拟结果来看,在9 km分辨率下嵌套3 km分辨率网格对台风路径模拟的误差较小,而单层9 km分辨率网格模拟的台风路径误差较大。通过对比两组方案模拟的台风路径、强度和结构,在模拟区域中使用嵌套高分辨率网格方案的模拟准确性有所提高。两种方案模拟的风场以及副热带高压十分接近。相比于单层网格,嵌套了高分辨率网格方案模拟的台风路径、强度误差更小,台风眼更小,位涡更强。

High resolution Mg/Ca ratios in the skeleton of a Porites lutea from the coastal area in the North of the South China Sea were precisely analyzed by ICP-MS. Compared with the instrument measured SST records, the Mg/Ca ratios strongly correlate with the SSTs, even in time of 1982/83 EI N(?)io. Therefore, a coral Mg/Ca thermometer for the North of the South China Sea was established.Based on ICP-MS technique it can report sea surface temperatures to an accuracy of±0.5℃.

为探究叶面喷施钙肥对玉米茎秆抗倒伏性能及产量形成的调控作用机制，选用盆栽试验，以玉米品种先玉335为供试材料，分别设置0(LCK)、3(LC1)、6(LC2)、9(LC3)和12 g/L(LC4)5个钙浓度处理，于玉米拔节期进行叶面喷施。结果表明，与LCK相比，LC2处理可显著降低玉米穗位高和重心高度，拔节期喷施适量钙肥（LC2和LC3）显著增加了茎秆基部抗折力和穿刺强度。叶面施钙可促进硬皮组织和维管束的发育，并且能显著提高玉米第3节间茎秆可溶性糖、纤维素和半纤维含量，且均在LC3处理下达最大值。叶面喷施LC2～LC4水平的钙肥也可明显提升玉米籽粒产量，其中LC2穗行数最大，为16.35,LC3处理百粒重最高，达31.36 g。从玉米茎秆的各项抗倒伏性能指标、茎秆化学成分及籽粒产量构成等综合表现来看，玉米叶片喷施钙肥最佳浓度范围为6～9 g/L，可以有效缩短基部节间长度，降低穗位高，促使玉米重心高度下移，同时优化茎秆中的氮、钾含量和纤维结构，促进维管束的发育，有效提高节间密度和充实度，进而提升茎秆机械强度，同时也能促进果穗发育，增加穗行数和百粒重和玉米产量。

针对大多数去雾算法对含有大面积天空区域的图像去雾效果不佳的问题,提出一种改进的暗通道先验去雾方法。首先,根据图像梯度信息分割出天空区域,在天空区域分割的基础上,结合大气光参考像素的高亮度和平滑性设定判别公式,合理地估计大气光值。其次,根据暗通道值的不同,采用分段线性函数对可调参数进行动态修正,解决过度去雾造成的局部阴影。然后,将亮通道模型和改进的暗通道先验模型估计的透射率进行融合,并采用导向滤波进行边缘优化。最后,结合大气散射模型,通过亮度补偿和对比度拉伸得到去雾图像。实验结果表明,改进方法能够有效地改善图像失真,增强图像的对比度和细节,尤其在保持天空区域的视觉真实性方面具有优势。
