| 1 | Assessing the USLE Crop and Management Factor C for Soil Erosion Modeling in a Large Mountainous Watershed in Central China显示文摘Due to the impoundment of the Yangtze River, the Three Gorges Dam in China fosters high land-use dynamics. Soil erosion is expected to increase dramatically. One of the key factors in soil erosion control is the vegetation cover and crop type. However, determining these factors adequately for the use in soil erosion modeling is very time-consuming especially for large mountainous areas, such as the Xiangxi (香溪) catchment in the Three Gorges area. In our study, the crop and management factor C was calculated using the fractional vegetation cover (CFVC) based on Landsat-TM images from 2005, 2006, and 2007 and on literature studies (CLIT). In 2007, the values of CFVC range between 0.001 and 0.98 in the Xiangxi catchment. The mean CFVC value is 0.05. CLIT values are distinctly higher, ranging from 0.08 to 0.46 with a mean value of 0.32 in the Xiangxi catchment. The mean potential soil loss amounts to 120.62 t/ha/a in the Xiangxi catchment when using CLIT for modeling. Based on CFVC, the predicted mean soil loss in the Xiangxi catchment is 11.50 t/ha/a. Therefore, CLIT appears to be more reliable than the C factor based on the fractional vegetation cover. | Sarah Schnbrodt Patrick Saumer Thorsten Behrens Christoph Seeber Thomas Scholten | 2010 | Journal of Earth Science2010，21，6： | 12 |
| 2 | Clinical features and visual outcomes of scleritis patients presented to tertiary care eye centers in Saudi Arabia显示文摘AIM: To describe the clinical features, systemic associations, treatment and visual outcomes in Saudi patients with scleritis.·METHODS: A retrospective chart review was performed for patients with scleritis presenting to two tertiary care eye hospitals in Riyadh, Saudi Arabia, from 2001 to 2011.Data were collected on the clinical features of scleritis,subtypes of scleritis, associated systemic disease,history of previous ocular surgery and medical therapy,including the use of immunosuppressants. Treatment outcomes were evaluated based on best-corrected visual acuity(BCVA) and response to treatment.·RESULTS: Of the 52 patients included in the study,non-necrotizing anterior scleritis was the most common type of scleritis in 22 patients(42.3%), followed by posterior scleritis in 14 patients(26.9%). The majority of cases, 31 patients(59.6%), were idiopathic in nature.Systemic associations were present in 12 patients(23.1%). Infectious scleritis was confirmed in 6 patients(11.5%): 3 with bacterial scleritis after pterygium excision, 2 patients with scleritis related to tuberculosis and 1 patient with scleritis resulting from herpes simplex infection. For the various subtypes of scleritis, BCVA values after treatment and time to remission significantly differed(P <0.05, all cases).Systemic immunosuppressive therapies in addition to steroids were administered to 46.2% of all patients. The T-sign was present on B-scan ultrasonography in 9(64.3%) of the 14 posterior scleritis patients.·CONCLUSION: Non-necrotizing anterior scleritis was the most common subtype of scleritis. Final visualoutcome and time to remission differed among the various scleritis subtypes. | Mohammad Al Barqi Ashley Behrens Abdullah M.Alfawaz | 2015 | International Journal of Ophthalmology(English edition)2015，8，6： | 4 |
| 3 | Enhanced microfracture techniques in cartilage knee surgery: Fact or fiction?显示文摘The limited intrinsic healing potential of human articular cartilage is a well-known problem in orthopedic surgery. Thus a variety of surgical techniques have been developed to reduce joint pain, improve joint function and delay the onset of osteoarthritis. Microfractures as a bone marrow stimulation technique present the most common applied articular cartilage repair procedure today. Unfortunately the deficiencies of fibrocartilaginous repair tissue inevitably lead to breakdown under normal joint loading and clinical results deteriorate with time. To overcome the shortcomings of microfracture, an enhanced microfracture technique was developed with an additional collagen Ⅰ/Ⅲ membrane(Autologous, Matrix-Induced Chondrogenesis, AMIC). This article reviews the pre-clinical rationale of microfractures and AMIC, presents clinical studies and shows the advantages and disadvantages of these widely usedtechniques. PubM ed and the Cochrane database were searched to identify relevant studies. We used a comprehensive search strategy with no date or language restrictions to locate studies that examined the AMIC technique and microfracture. Search keywords included cartilage, microfracture, AMIC, knee, ChondroGide. Besides this, we included our own experiences and study authors were contacted if more and non published data were needed. Both cartilage repair techniques represent an effective and safe method of treating full-thickness chondral defects of the knee in selected cases. While results after microfracture deteriorate with time, mid-term results after AMIC seem to be enduring. Randomized studies with long-term followup are needed whether the grafted area will maintain functional improvement and structural integrity over time. | Stefan Bark Tomasz Piontek Peter Behrens Sabiah Mkalaluh Deike Varoga Justus Gille | 2014 | World Journal of Orthopedics2014，5，4： | 3 |

| 11 | 白内障摘除术后的急性眼内炎文献的系统回顾显示文摘目的:确定白内障摘除术后随时间推移报道的急性眼内炎的发生率并探讨可能引起的因素,如白内障手术切口类型。
方法:以白内障摘除术、眼内炎及术后并发症为关键词,对1963—2003年PubMed上的英文文献进行广泛检索。并进行系统性回顾。附加的研究确认为与其相切题的文献和已发表的会议记录。在可能提供的情况下。记录手术方式。对用不同手术切口技术导致眼内炎发展的累计发生率和相关危险度进行评估。用不同切口的技术评估累计眼内炎的发生率与发展眼内炎的相对危险因素。
结果:从4916篇特定且具潜在相关性的引文中对其中215篇涉及眼内炎且符合入选标准的研究进行分析。总共3140650例白内障手术后,累计0.128%发生眼内炎。然而,急性眼内炎的发生率随着时代不同而改变。与过去lO年相比。2000年以来发生率明显升高(相对危险度,2.44;95%可信区间,2.27—2.61)。2000—2003年眼内炎发生率为0.265%。20世纪90年代为0.087%,80年代为0.158%,70年代为0.327%。并且,与1991年及以前相比,1992年以来发生率有上升趋势。手术切口类型似乎是产生显著影响的危险因素,因为1992—2003年中,经透明角膜切口白内障手术后眼内炎发生率为0.189%。与经巩膜切口0.074%(相对危险度,2.55;95%可信区间,1.75—3.71)及经角巩膜缘切口0.062%(相对危险度,3.06;95%可信区间,2.48—3.76)的发生率相比较,手术切口类型似乎是产生显著影响的危险因素。
结论:这一系统回顾显示,与白内障摘除术相关眼内炎的发生率在过去10年中有所上升。其发生频率的上升趋势与当前无缝线透明角膜白内障摘除术的进展相一致。 | Mehran Taban Ashley Behrens Robert L. Newcomb Matthew Y. Nobe Golnaz Saedi Paula M. Sweet Peter J. McDonnell 胡妙妙(译) 蒋幼芹(校) | 2006 | 美国医学会眼科杂志(中文版)2006，18，1： | 2 |
