| 1 | Return to sport following tibial plateau fractures: A systematic review显示文摘AIM To systemically review all studies reporting return to sport following tibial plateau fracture, in order to provide information on return rates and times to sport, and to assess variations in sporting outcome for different treatment methods.METHODS A systematic search of CINAHAL, Cochrane, EMBASE, Google Scholar, MEDLINE, PEDro, Scopus, SPORTDiscus and Web of Science was performed in January 2017 using the keywords 'tibial', 'plateau', 'fractures', 'knee', 'athletes', 'sports', 'non-operative', 'conservative', 'operative', 'return to sport'. All studies which recorded return rates and times to sport following tibial plateau fractures were included. RESULTS Twenty-seven studies were included: 1 was a randomised controlled trial, 7 were prospective cohort studies, 16 were retrospective cohort studies, 3 were case series. One study reported on the outcome of conservative management(n = 3); 27 reported on the outcome of surgical management(n = 917). Nine studies reported on Open Reduction Internal Fixation(ORIF)(n = 193), 11 on Arthroscopic-Assisted Reduction Internal Fixation(ARIF)(n = 253) and 7 on Frame-Assisted Fixation(FRAME)(n = 262). All studies recorded 'return to sport'rates. Only one study recorded a 'return to sport' time. The return rate to sport for the total cohort was 70%. For the conservatively-managed fractures, the return rate was 100%. For the surgically-managed fractures, the return rate was 70%. For fractures managed with ORIF, the return rate was 60%. For fractures managed with ARIF, the return rate was 83%. For fractures managed with FRAME was 52%. The return rate for ARIF was found to be significantly greater than that for ORIF(OR 3.22, 95%CI: 2.09-4.97, P < 0.001) and for FRAME(OR 4.33, 95%CI: 2.89-6.50, P < 0.001). No difference was found between the return rates for ORIF and FRAME(OR 1.35, 95%CI: 0.92-1.96, P = 0.122). The recorded return time was 6.9 mo(median), from a study reporting on ORIF.CONCLUSION Return rates to sport for tibial plateau fractures remain limited compared to other fractures. ARIF provides the best return rates. There is limited data regarding return times to sport. Further research is required to determine return times to sport, and to improve return rates to sport, through treatment and rehabilitation optimisation. | Greg A J Robertson Seng J Wong Alexander M Wood | 2017 | World Journal of Orthopedics2017，8，7： | 10 |
| 2 | Current Status and Future Challenges of Weather Radar Polarimetry: Bridging the Gap between Radar Meteorology/Hydrology/Engineering and Numerical Weather Prediction显示文摘After decades of research and development, the WSR-88 D(NEXRAD) network in the United States was upgraded with dual-polarization capability, providing polarimetric radar data(PRD) that have the potential to improve weather observations,quantification, forecasting, and warnings. The weather radar networks in China and other countries are also being upgraded with dual-polarization capability. Now, with radar polarimetry technology having matured, and PRD available both nationally and globally, it is important to understand the current status and future challenges and opportunities. The potential impact of PRD has been limited by their oftentimes subjective and empirical use. More importantly, the community has not begun to regularly derive from PRD the state parameters, such as water mixing ratios and number concentrations, used in numerical weather prediction(NWP) models.In this review, we summarize the current status of weather radar polarimetry, discuss the issues and limitations of PRD usage, and explore potential approaches to more efficiently use PRD for quantitative precipitation estimation and forecasting based on statistical retrieval with physical constraints where prior information is used and observation error is included. This approach aligns the observation-based retrievals favored by the radar meteorology community with the model-based analysis of the NWP community. We also examine the challenges and opportunities of polarimetric phased array radar research and development for future weather observation. | Guifu ZHANG Vivek N.MAHALE Bryan J.PUTNAM Youcun QI Qing CAO ANDrew D.BYRD Petar BUKOVCIC Dusan S.ZRNIC Jidong GAO Ming XUE Youngsun JUNG Heather D.REEVES Pamela L.HEINSELMAN AlexANDer RYZHKOV Robert D.PALMER Pengfei ZHANG Mark WEBER Greg M.MCFARQUHAR Berrien MOORE III Yan ZHANG Jian ZHANG J.VIVEKANANDAN Yasser AL-RASHID Richard L.ICE Daniel S.BERKOWITZ Chong-chi TONG Caleb FULTON Richard J.DOVIAK | 2019 | Advances in Atmospheric Sciences2019，36，6： | 9 |

| 4 | Lower limb stress fractures in sport:Optimising their management and outcome显示文摘Stress fractures in sport are becoming increasing more common,comprising up to 10%of all of sporting injuries.Around 90%of such injuries are located in the lower limb.This articles aims to define the optimal management of lower limb stress fractures in the athlete,with a view to maximise return rates and minimise return times to sport.Treatment planning of this condition is specific to the location of the injury.However,there remains a clear division of stress fractures by'high'and'low'risk.'Low risk'stress fractures are those with a low probability of fracture propagation,delayed union,or non-union,and so can be managed reliably with rest and exercise limitation.These include stress fractures of the PosteroMedial Tibial Diaphysis,Metatarsal Shafts,Distal Fibula,Medial Femoral Neck,Femoral Shaft and Calcaneus.'High risk'stress fractures,in contrast,have increased rates of fracture propagation,displacement,delayed and non-union,and so require immediate cessation of activity,with orthopaedic referral,to assess the need for surgical intervention.These include stress fractures of the Anterior Tibial Diaphysis,Fifth Metatarsal Base,Medial Malleolus,Lateral Femoral Neck,Tarsal Navicular and Great Toe Sesamoids.In order to establish the optimal methods for managing these injuries,we present and review the current evidence which guides the treatment of stress fractures in athletes.From this,we note an increased role for surgical management of certain high risk stress fractures to improve return times and rates to sport.Following this,key recommendations are provided for the management of the common stress fracture types seen in the athlete.Five case reports are also presented to illustrate the application of sportfocussed lower limb stress fracture treatment in the clinical setting. | Greg A J Robertson Alexander M Wood | 2017 | World Journal of Orthopedics2017，8，3： | 7 |
| 5 | Hip hemi-arthroplasty for neck of femur fracture:What is the current evidence?显示文摘This editorial reviews and summarises the current evidence(meta-analyses and Cochrane reviews) relating to the use of hip hemi-arthroplasty for neck of femur fractures. Regarding the optimal surgical approach,two recent meta-analyses have found that posterior approaches are associated with: higher rates of dislocation compared to lateral and anterior approaches; and higher rates of re-operation compared to lateral approaches. Posterior approaches should therefore be avoided when performing hip hemi-arthroplasty procedures. Assessing the optimal prosthesis head component,three recent meta-analyses and one Cochrane review have found that while unipolar hemiarthroplasty can be associated with increased rates of acetabular erosion at short-term follow-up(up to 1 year),there is no significant difference between the unipolar hemi-arthroplasty and bipolar hemi-arthroplasty for surgical outcome,complication profile,functional outcome and acetabular erosion rates at longer-term follow-up(2 to 4 years). With bipolar hemi-arthroplasty being the more expensive prosthesis,unipolar hemi-arthroplasty is the recommended option. With regards to the optimal femoral stem insertion technique,three recent metaanalyses and one Cochrane Review have found that,while cemented hip hemi-arthroplasties are associated with a longer operative time compared to uncemented Hip Hemi-arthroplasties,cemented prostheses have lower rates of implant-related complications(particularly peri-prosthetic femoral fracture) and improved postoperative outcome regarding residual thigh pain and mobility. With no significant difference found between the two techniques for medical complications and mortality,cemented hip hemi-arthroplasty would appear to be the superior technique. On the topic of wound closure,one recent meta-analysis has found that,while staples can result in a quicker closure time,there is no significant difference in post-operative infections rates or wound healing outcomes when comparing staples to sutures. Therefore,either suture or staple wound closure techniques appear equally appropriate for hip hemiarthroplasty procedures. | Greg AJ Robertson Alexander M Wood | 2018 | World Journal of Orthopedics2018，9，11： | 4 |

| 19 | 从木材解剖学视角看公元6世纪中期晚古小冰期的开始时间显示文摘公元536~540年间的大规模火山喷发使得晚古小冰期成为过去两千年最为寒冷的时期.然而,受限于现有气候代用资料的时间分辨率和空间覆盖度,晚古小冰期的开始时间和空间范围仍存有争议.本文分析了全球23个森林样点、20个树种的106个树轮样本资料,从细胞尺度揭示了公元530~550年间北半球发生的短暂夏季冷却现象.经过交叉定年和染色处理后,在北半球的树轮样品中共识别出89个蓝轮(缺失细胞壁木质化过程)、9个霜轮(细胞分裂受阻)和93个浅轮(细胞壁增厚减弱).研究结果表明,公元536年7月中旬至8月初期间整个北美和欧亚大陆均发生了最剧烈的温度下降,而更多的区域性“冷夏”出现于公元532年、540~543年和548年.然而,本研究在南半球的树轮资料中并未发现异常的解剖结构,其原因可能与南半球的海洋热惯性减缓了火山降温效应有关,也或与南半球其时正值非生长季有关.相较于传统的树轮年代学方法,本研究的木材解剖学的方法能为地球系统模式提供更为精细的参考标准,有望服务于气候与人类历史交叉学科研究,同时对“全球气候平均”概念的使用提出质疑. | Ulf Büntgen Alan Crivellaro Dominique Arseneault Mike Baillie David Barclay Mauro Bernabei Jarno Bontadi Gretel Boswijk David Brown Duncan AChristie Olga VChurakova Edward RCook Rosanne D’Arrigo Nicole Davi Jan Esper Patrick Fonti Ciara Greaves Rashit MHantemirov Malcolm KHughes Alexander VKirdyanov Paul JKrusic Carlos Le Quesne Fredrik CLjungqvist Michael McCormick Vladimir SMyglan Kurt Nicolussi Clive Oppenheimer Jonathan Palmer 秦春 Frederick Reinig Matthew Salzer Markus Stoffel Max Torbenson Mirek Trnka Ricardo Villalba Nick Wiesenberg Greg Wiles 杨保 Alma Piermattei | 2022 | Science Bulletin2022，67，22： | 0 |
| 20 | Broadband 1-GHz mid-infrared frequency comb显示文摘Mid-infrared(MIR)spectrometers are invaluable tools for molecular fingerprinting and hyper-spectral imaging.Among the available spectroscopic approaches,GHz MIR dual-comb absorption spectrometers have the potential to simultaneously combine the high-speed,high spectral resolution,and broad optical bandwidth needed to accurately study complex,transient events in chemistry,combustion,and microscopy.However,such a spectrometer has not yet been demonstrated due to the lack of GHz MIR frequency combs with broad and full spectral coverage.Here,we introduce the first broadband MIR frequency comb laser platform at 1 GHz repetition rate that achieves spectral coverage from 3 to 13 μm.This frequency comb is based on a commercially available 1.56 μm mode-locked laser,robust all-fiber Er amplifiers and intra-pulse difference frequency generation(IP-DFG)of few-cycle pulses in x(2)nonlinear crystals.When used in a dual comb spectroscopy(DCS)configuration,this source will simultaneously enable measurements with μs time resolution,1 GHz(0.03 cm-1)spectral point spacing and a full bandwidth of>5 THz(>166 cm-1)anywhere within the MIR atmospheric windows.This represents a unique spectroscopic resource for characterizing fast and non-repetitive events that are currently inaccessible with other sources. | Nazanin Hoghooghi Sida Xing Peter Chang Daniel Lesko Alexander Lind Greg Rieker Scott Diddams | 2022 | Light(Science & Applications)2022，11，10： | 0 |
