1New insights in the treatment of acromioclavicular separation显示文摘A direct force on the superior aspect of the shoulder may cause acromioclavicular(AC) dislocation or separation. Severe dislocations can lead to chronic impairment, especially in the athlete and high-demand manual laborer. The dislocation is classified according to Rockwood. Types Ⅰ?and Ⅱ are treated nonoperatively, while types Ⅳ, Ⅴ and Ⅵ are generally treated operatively. Controversy exists regarding the optimal treatment of type Ⅲ dislocations in the high-demand patient. Recent evidence suggests that these should be treated nonoperatively initially. Classic surgical techniques were associated with high complication rates, including recurrent dislocations and hardware breakage. In recent years, many new techniques have been introduced in order to improve the outcomes. Arthroscopic reconstruction or repair techniques have promising short-term results. This article aims to provide a current concepts review on the treatment of AC dislocations with emphasis on recent developments.Christiaan J A van Bergen Annelies F van Bemmel Tjarco D W Alta Arthur van Noort 2017World Journal of Orthopedics2017,8,12:12
2Image denoising and deblurring: non-convex regularization, inverse diffusion and shock filter显示文摘A large number of applications in image processing and computer vision depend on image quality. In this paper, main concerns are image denoising and deblurring simultaneously in a restoration task by three types of methodologies: non-convex regularization, inverse diffusion and shock filter. We discuss their relations in the context of image deblurring: the inverse diffusion implied by the non-convex regularization, and the superior ability of deblurring edge of the shock filter to that of the inverse diffusion, both in 1D and 2D cases. Finally, we propose a region-based adaptive anisotropic diffusion with shock filter method, which shows advantages of deblurring edges, denoising and smoothing contours in experiments, compared with some related methods. Therein an idea of 'divide and rule' is introduced.FU ShuJun 1,2,3 , ZHANG CaiMing 2 & TAI XueCheng 3,4 1 School of Mathematics, Shandong University, Jinan 250100, China 2 School of Computer Science and Technology, Shandong University, Jinan 250101, China 3 School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore 639798, Singapore 4 Department of Mathematics, University of Bergen, Bergen 5008, Norway 2011Science China(Information Sciences)2011,54,6:8
3伊通上地幔剪切带捕虏体中富铝尖晶石的地球化学特征显示文摘伊通上地幔剪切带中辉石岩、二辉橄榄岩和易剥橄榄岩是3个主要地幔捕虏体,其中尖晶石的化学成分以富铝为特征。辉石岩中尖晶石在薄片下呈绿色,为铝含量高、铬含量低的铝尖晶石;与之相比,二辉橄榄岩和易剥橄榄岩中尖晶石在薄片下呈棕色,为铝含量相对较低、铬含量相对较高的富铝铬尖晶石。尖晶石的颜色与Al、Mg、Cr、Fe含量有关。在不同捕虏体中尖晶石成分具有不同的变化范围,尖晶石化学成分之间存在一定的相关性,Mg#与Cr#,Mg#与Fe2+和Cr与Al呈现负相关性,而Mg#与Al#呈现出正相关性,反映不同捕虏体中尖晶石具有同一来源和成因联系。在地幔岩石部分熔融和结晶过程中Cr和Al的分异明显。固溶体条件下基本服从八面体Cr Al替代关系,而不同地幔捕虏体中尖晶石的成分差异是岩浆部分熔融和结晶过程中元素分异、固溶体离子替代的结果。贾大成 邢立新 潘军 M.J.van Bergen H.van Roermund 2006吉林大学学报(地球科学版)2006,36,4:7

5过流式UV/H_(2)O_(2)反应器中阿特拉津降解动力学的测定及模拟评估显示文摘紫外高级氧化工艺在降解去除水中微量有机污染物方面具有良好的应用前景,已有大量相关基础研究在实验室序批式反应器内完成,然而,在实际工程中采用的过流式反应器中的不同水流形态可能会对反应动力学和工艺效率产生影响。为此,采用过流式UV/H_(2)O_(2)反应器降解水中阿特拉津(ATZ),分别考察了H_(2)O_(2)浓度、反应器内径对ATZ降解效率和工艺经济性的影响,同时评估了稳态假设(SSA)模型在过流式UV/H_(2)O_(2)反应器中应用的可行性。结果表明:过流式反应器中UV/H_(2)O_(2)工艺对ATZ有着良好的去除效果,降解过程基本符合拟一级反应动力学(R^(2)>0.95);虽然反应器内流态并非完全混合,SSA模型仍可准确预测反应器中目标污染物的降解,模拟和实验结果相对偏差绝大多数不超过20%;在考察的H_(2)O_(2)浓度范围内,随着浓度的增加,不同反应器中ATZ的降解速率均逐渐增大,特别在H_(2)O_(2)浓度为0.2 mmol·L^(−1)时,内径为35 mm的反应器中ATZ降解速率常数达到5.8×10^(−2)s^(−1),是单独UV辐照下的4倍以上。由于平均紫外强度的变化,增大反应器内径将导致ATZ基于时间的降解速率常数的降低,但对基于紫外剂量的速率常数影响不大。此外,E_(EO)分析结果表明,增加H_(2)O_(2)浓度和增大反应器内径均可以降低ATZ去除的单位能耗。詹露梦 李文涛 李梦凯 JENSEN Marina Bergen 张淼 强志民 2021环境工程学报2021,15,3:4

7Total elbow arthroplasty is moving forward: Review on past, present and future显示文摘The elbow joint is a complex joint, which, when impaired in function, leads to severe disability. In some cases however, an arthroplasty might be an appropriate treatment. In the past four decades, large steps havebeen taken to optimize this treatment in order to achieve better post-operative outcomes. To understand these progresses and to discover aspects for upcoming improvements, we present a review on the past developments, the present state of affairs and future developments which may improve patient care further.Ante Prki?

8Diagnosing, planning and evaluating osteochondral ankle defects with imaging modalities显示文摘This current concepts review outlines the role of diffe-rent imaging modalities in the diagnosis, preoperative planning, and follow-up of osteochondral ankle defects. An osteochondral ankle defect involves the articular cartilage and subchondral bone(usually of the talus) and is mostly caused by an ankle supination trauma. Conventional radiographs are useful as an initial imaging tool in the diagnostic process, but have only moderate sensitivity for the detection of osteochondral defects. Computed tomography(CT) and magnetic resonance imaging(MRI) are more accurate imaging modalities. Recently, ultrasonography and single photon emission CT have been described for the evaluation of osteochondral talar defects. CT is the most valuable modality for assessing the exact location and size of bony lesions. Cartilage and subchondral bone damage can be visualized using MRI, but the defect size tends to be overestimated due to bone edema. CT with the ankle in full plantar flexion has been shown a reliable tool for preoperative planning of the surgical approach. Postoperative imaging is useful for objective assessment of repair tissue or degenerative changes of the ankle joint. Plain radiography, CT and MRI have been used in outcome studies, and different scoring systems are available.Christiaan JA van Bergen Rogier M Gerards Kim TM Opdam Maaike P Terra Gino MMJ Kerkhoffs 2015World Journal of Orthopedics2015,6,11:3

14北京市城区2005-2015年屋顶绿化发展趋势、分布格局及政策推动显示文摘基于北京市各城区2005—2015年每年屋顶绿化建设面积及相关政策,明确了北京市屋顶绿化自推广以来的建设状况,分析了屋顶绿化建设在各城区及各业主单位类型的分布,研究了屋顶绿化在城市绿化覆盖中的比例及变化。同时,探究了相关政策对屋顶绿化发展的推动作用。结果表明:2005—2015年北京市城区共建设屋顶绿化1.23×10~6m^2,平均每年建设1.12×10~5m^2;截至2015年,各城区累计建设屋顶绿化面积的排序为朝阳区>东城区>海淀区>西城区>丰台区>石景山区;2011—2015年,党政机关等事业单位、学校及科研机构和医院所属公共机构建筑是北京市城区实施屋顶绿化的主体,占各年屋顶绿化建设总面积的比例为62.0%~80.4%;2011—2015年,屋顶绿化在城市绿化覆盖中所占比例逐年提高,且该比例表现为首都功能核心区大于城市功能拓展区;截至2015年,北京市城区屋顶绿化面积仅占城市绿化覆盖面积的0.30%,未来对于增加北京市城市绿化覆盖面积的潜力还很大。建议今后可通过强化鼓励措施和制定强制措施进一步推进北京市屋顶绿化的发展。刘博杰 王仕豪 逯非 王雪妍 Marina Bergen Jensen 郑善文 刘栗 单明芸 赵克贤 2018生态学杂志2018,37,5:2
15Developments in diagnosis and treatment of paediatric septic arthritis显示文摘Acute septic arthritis in children is an orthopaedic emergency.A delay in diagnosis and inappropriate treatment can result in devastating damage to the joint with lifelong disability as a consequence.The clinical presentation can be a diagnostic challenge,especially in young children.A recent systematic review showed that joint tenderness and fever are important signals of septic arthritis.Ultrasound is helpful in detecting the presence of a joint effusion.Plain radiographs may show bone changes but magnetic resonance imaging is the most reliable imaging study for detecting concomitant osteomyelitis.The diagnosis of acute septic arthritis is highly suggestive when pus is aspirated from the joint,in case of a positive culture or a positive gram stain of the joint fluid,or if there is a white blood-cell count in the joint fluid of more than 50000/mm3.Staphylococcus aureus is the most commonly cultured organism.Recent systematic reviews have identified the most effective drainage techniques,including needle aspiration,arthroscopy and arthrotomy,depending on the affected joint.After the drainage procedure it is important to monitor the clinical and laboratory outcomes.Additional drainage procedures may be necessary in select cases.Cornelia M Donders Anne J Spaans Herbert van Wering Christiaan JA van Bergen 2022World Journal of Orthopedics2022,13,2:2
