1Staging accuracy of esophageal cancer by endoscopic ultrasound:A meta-analysis and systematic review显示文摘AIM: To evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer. METHODS: Only EUS studies confirmed by surgery were selected. Articles were searched in Medline and Pubmed. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratio. Pooling was conducted by both the Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS: Forty-nine studies (n = 2558) which met the inclusion criteria were included in this analysis. Pooled sensitivity and specificity of EUS to diagnose T1 was 81.6% (95% CI: 77.8-84.9) and 99.4% (95% CI: 99.0-99.7), respectively. To diagnose T4, EUS had a pooled sensitivity of 92.4% (95% CI: 89.2-95.0) and specificity of 97.4% (95% CI: 96.6-98.0). With Fine Needle Aspiration (FNA), sensitivity of EUS to diagnose N stage improved from 84.7% (95% CI: 82.9-86.4) to 96.7% (95% CI: 92.4-98.9). The P value for the χ2 test of heterogeneity for all pooled estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity in accurately diagnosing the TN stage of esophageal cancer. EUS performs better with advanced (T4) than early (T1) disease. FNA substantially improves the sensitivity and specificity of EUS in evaluating N stage disease. EUS should be strongly considered for staging esophageal cancer.Srinivas R Puli Jyotsna BK Reddy Matthew L Bechtold Daphne Antillon Jamal A Ibdah Mainor R Antillon 2008World Journal of Gastroenterology2008,14,10:55
2青藏高原东缘古近纪粗碎屑岩沉积学及其构造意义显示文摘青藏高原东缘古近纪盆地的填图和沉积学研究表明,在青藏高原东缘区域性走滑-挤压构造背景下形成的古近纪盆地内广泛发育厚层—巨厚层状的紫红色粗碎屑岩系。其沉积特征指示为一种近源快速堆积的泥石流和辫状河道沉积体,形成于干旱炎热气候条件下的典型陆内冲积扇环境。盆地充填序列、粗碎屑岩层序、动植物化石和盆地内岩浆岩^(40)Ar-^(39)Ar年代学等综合研究结果表明,古近纪盆地内粗碎屑岩大约形成于38~29 Ma。该时期与青藏高原东缘北段(横断山地区)古近纪盆地的形成和南段(兰坪—思茅地区)大盆地的裂解时间基本一致,这很可能预示着青藏高原在晚始新世—早渐新世期间曾发生过整体的快速构造隆升。周江羽 王江海 An YIN BK HORTON MS SPURLIN 2003地质学报2003,77,2:21
3下肢浅静脉治疗术后的加压疗法:美国静脉论坛血管、外科学会、美国静脉学会、血管医学学会和国际静脉联盟的临床实践指南显示文摘一、指南的由来下肢浅静脉治疗术后应用压力治疗的方式是几代血管外科医师多年临床经验积累所得,现主要应用于大隐静脉剥脱术、下肢静脉点状剥脱术及静脉硬化治疗等。目前单就静脉硬化治疗而言,术后压力治疗的推荐也是基于相关文献及实验验证[1],但对于其他术式,尤其是对于大隐静脉的热消融术,目前还没有形成规范统一的建议,这也使得当前的压力治疗具有很大的临床差异性。Lurie F Lal BK Antignani PL Blebea J Bush R Caprini J Davies A Forrestal M Jacobowitz G Kalodiki E Killewich L Lohr J Ma H Mosti G Partsch H Rooke T Wakefield T 李丹(译) 陈程浩(译) 牛传强(译) 张靖(译) 黄建忠(译) 2020中华介入放射学电子杂志2020,8,4:16
4FREDDY激光器的碎石效率的体外分析显示文摘背景和目的 双频双脉冲Nd :Yag(FREDDY)激光 (德国W .O .M .公司生产 )是一个短脉冲 ,双频率 ( 5 3 2nm和 10 64nm)的固体激光器。该激光器功率小 ,成本低 ,目前已在腔内碎石术中得到应用。我们设计了一个试验 ,以测试在不同能量和不同频率下的碎石效率。材料和方法 40个预先称过重量的硫酸钙石头被分成 4组 ,在 5Hz和 10Hz情况下 ,分别碎石 2min和 4min。一个水下的试验装置包括一个支架和一个容器 ,使得石英玻璃光纤可以直接抵住石头 ,发射激光。光纤被剥离成直径为 2 80 μm的裸露光纤 ,以保证最佳的能量传输。碎石完成后 ,所有的残余颗粒都落在容器内 ,晾干 48小时后 ,再重新称重 ,根据重量缺失的百分比来测试碎石效果。结果 5Hz时 ,碎石 2min的重量缺失为 2 4%;碎石 4min的重量缺失为 5 4%。 10Hz时 ,碎石 2min的情况与 5Hz时碎石 4min的结果相似 ,重量缺失为 5 1%;碎石 4min的重量缺失为 64 %,原先估计这么高的能量设置 ,重量缺失应该更大些。在高能量发射时 ,可以观察到光纤有损耗 ,这可能是导致碎石效率下降的原因。结论 FREDDY激光器在 5Hz时碎石 4min ,和在 10Hz时碎石 2min的效率是同等的 ,提示传输到结石的能量与碎石效率的相关性很好。而 10Hz、4min组的碎石效率比预期的略有下降 ,?Delvecchio FC Auge BK Brizuela RM Weizer AZ Zhong P Preminger GM 2004国外医学(泌尿系统分册)2004,24,4:10
5急性脊髓损伤患者治疗的临床操作指南:关于MRI基线在临床治疗决策与结果预测中作用的几点建议(英文)显示文摘The objective of this guideline is to outline the role of magnetic resonance imaging(MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury(SCI).Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI.This review focused on longitudinal studies that controlled for baseline neurologic status.A multidisciplinary Guideline Development Group(GDG) used this information,their clinical expertise,and patient input to develop recommendations on the use of MRI for SCI patients.Based on GRADE(Grading of Recommendation,Assessment,Development and Evaluation),a strong recommendation is worded as ' we recommend,' whereas a weaker recommendation is indicated by 'we suggest.' Results Based on the limited available evidence and the clinical expertise of the GDG,our recommendations were:(1) 'We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention,when feasible,to facilitate improved clinical decision-making'(quality of evidence,very low) and(2) 'We suggest that MRI should be performed in adult patients in the acute period following SCI,before or after surgical intervention,to improve prediction of neurologic outcome '(quality of evidence,low).Conclusions These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI.Fehlings MG Martin AR Tetreault LA Aarabi B Anderson P Arnold PM Brodke D Burns AS Chiba K Dettori JR Furlan JC Hawryluk G Holly LT Howley S Jeji T Kalsi-Ryan S Kotter M Kurpad S Kwon BK Marino RJ Massicotte E Merli G Middleton JW Nakashima H Nagoshi N Palmieri K Singh A Skelly AC Tsai EC Vaccaro A Wilson JR Yee A Harrop JS 2017中华神经外科疾病研究杂志2017,16,6:8
6全膝关节置换翻修术中骨缺损的处理显示文摘全膝关节翻修术中导致骨缺损的因素很多,包括松动假体的沉降、应力遮挡效应、假体周围骨溶解、坏死及感染等。对于骨缺损处理方法的选择,应综合考虑缺损区的大小及位置,患者的年龄、健康状况以及参与术后康复训练的能力等多方面因素。1骨缺损的分型骨缺损可分为包容性和非包容性骨缺损。包容性骨缺损周围仍有完整的骨皮质进行包绕,翻修时可通过颗粒骨植骨或骨水泥螺钉技术进行处理;而非包容性骨缺损周围的骨皮质部分会全部丧失,通常需要通过组培式垫块、结构性植骨、干骺端金属袖套或锥形套进行重建。Daines BK Dennis DA 张涛 尹庆水 2012中国骨科临床与基础研究杂志2012,4,5:7

13Assessment of knowledge and attitude about basic life support among dental interns and postgraduate students in Bangalore city,India显示文摘BACKGROUND: Life-threatening emergencies can occur at anytime, at anywhere and in anyone. Effective management of an emergency situation in the dental office is ultimately the dentist's responsibility. The lack of training and inability to cope with medical emergencies can lead to tragic consequences and sometimes legal complications. Therefore, health professionals including dentists must be well prepared to deal with medical emergencies. This study was undertaken to assess the knowledge about and attitude towards basic life support(BLS) among dental interns and postgraduate students in Bangalore city, India.METHODS: A cross sectional survey was conducted among dental interns and postgraduate students from May 2014 to June 2014 since few studies have been conducted in Bangalore city. A questionnaire with 17 questions regarding the knowledge about and attitude towards BLS was distributed to 202 study participants.RESULTS: The data analyzed using the Chi-square test showed that dental interns and postgraduate students had average knowledge about BLS. In the 201 participants, 121(59.9%) had a positive attitude and 81(40.1%) had a negative attitude towards BLS.CONCLUSIONS: Cardiopulmonary resuscitation should be considered as part of the dental curriculum. Workshops on a regular basis should be focused on skills of cardiopulmonary resuscitation for dental students.Dhage Pundalika Rao Narayan Suvarna V Biradar Mayurnath T Reddy Sujatha BK 2015World Journal of Emergency Medicine2015,6,2:2
