| 1 | Computed tomography overestimation of esophageal tumor length: Implications for radiotherapy planning显示文摘AIM:To assess the relationship between preoperative computed tomography(CT)and postoperative pathological measurements of esophageal tumor length and the prognostic significance of CT tumor length data.METHODS:A retrospective study was carried out in 56 patients who underwent curative esophagogastrectomy.Tumor lengths were measured on the immediate preoperative CT and on the post-operative resection specimens.Inter-and intra-observer variations in CT measurements were assessed.Survival data were collected.RESULTS:There was a weak correlation between CT and pathological tumor length(r=0.30,P=0.025).CT lengths were longer than pathological lengths in 68%(38/56)of patients with a mean difference of 1.67 cm(95%CI:1.18-2.97).The mean difference in measurements by two radiologists was 0.39 cm(95% CI:-0.59-1.44).The mean difference between repeat CT measured tumor length(intra-observer variation) were 0.04 cm(95%CI:-0.59-0.66)and 0.47 cm (95%CI:-0.53-1.47).When stratified,patients not receiving neoadjuvant chemotherapy showed a strong correlation between CT and pathological tumor length(r =0.69,P=0.0014,n=37)than patients that did(r= 0.13,P=0.43,n=19).Median survival with CT tumor length>5.6 cm was poorer than with smaller tumors,but the difference was not statistically significant.CONCLUSION:Esophageal tumor length assessed using CT does not reflect pathological tumor extent and should not be the only modality used for management decisions,particularly for planning radiotherapy. | Karim Sillah Luke R Williams Hans-Ulrich Laasch Azeem Saleem Gillian Watkins Susan A Pritchard Patricia M Price Catharine M West Ian M Welch | 2010 | World Journal of Gastrointestinal Oncology2010，2，4： | 10 |
| 2 | 钠-葡萄糖共转运蛋白-2抑制剂或胰高血糖素样肽-1受体激动剂治疗成人2型糖尿病:临床实践指南显示文摘临床问题对于存在不同心血管风险及肾脏结局的2型糖尿病患者,在原有生活方式干预和/或其他降糖药物的基础上加用钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂的获益及风险是什么?现行做法几十年来,2型糖尿病的治疗决策都以控制血糖为主导。SGLT-2抑制剂和GLP-1受体激动剂在传统观念中常被用于二甲双胍治疗后血糖仍控制不佳的患者。目前这一现状已经发生了改变,这得益于多项临床研究结果。研究显示SGLT-2抑制剂和GLP-1受体激动剂拥有独立于药物降糖作用之外的对于动脉粥样硬化性心血管病(CVD)和慢性肾脏病(CKD)的获益。建议本指南阐述了针对不同风险分层的成人2型糖尿病患者使用SGLT-2抑制剂或GLP-1受体激动剂的建议。•伴有3种或更少的心血管风险因素且不存在CVD或CKD:不建议启动SGLT-2抑制剂或GLP-1受体激动剂治疗。(推荐等级:弱)•伴有3种以上心血管风险因素且不存在CVD或CKD:建议启动SGLT-2抑制剂治疗,不建议启动GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD或CKD:建议启动SGLT-2抑制剂治疗和GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD和CKD:建议启动SGLT-2抑制剂治疗(推荐等级:强)和GLP-1受体激动剂治疗。(推荐等级:弱)•对于那些想要进一步降低CVD和CKD结局风险的患者:推荐优先启用SGLT-2抑制剂治疗而非GLP-1受体激动剂治疗。(推荐等级:弱)这项指南是如何制订的一个由患者、临床医生和方法学家共同组成的国际小组提出了这些推荐意见。这些推荐意见基于可信度较高的指南的标准,并使用GRADE分级方法进行评估。该小组采用了息者个体化的观点。证据一项关于获益与风险的系统综述和网络meta分析(764项随机对照研究,包括421346例参与者)发现SGLT-2抑制剂和GLP-1受体激动剂可以降低总体死亡率、心肌梗死发生率、终末期肾病或肾衰竭的发生率(中等至高等质量的证据)。在不同的亚组中这些药物对卒中、因心力衰竭所致住院和其他主要不良事件有不同的影响。药物绝对获益的程度因患者个体风险的不同有很大的差异。(例如,对于接受了超过5年药物治疗的1000例患者,在最低风险人群中死亡人数减少了5人,在最高风险人群中死亡人数减少了48人)。一项关于预后的综述确认了14种风险预测模型,其中一种(RECODe)在证据总结中报告了大部分基线风险评估数据,小组利用该模型以支持风险分层的建议。考虑到患者的价值观及个体差异,指南推荐的支撑证据包括一项对已发表论文的系统综述、一项患者焦点小组研究、一项临床问题总结,以及一项指南调查。指南解读我们依据不同的CVD和CKD风险水平,综合考虑获益、风险和其他因素的平衡,以及每一个风险组别的实际问题,来对推荐意见进行分层。本指南强烈建议CVD和CKD患者使用SGLT-2抑制剂治疗,这说明专家组认为其具有显著的获益。而对于其他成人2型糖尿病患者,推荐等级较弱,这说明专家组想要在获益、风险及治疗花费上取得一个更好的平衡。临床医生通过该指南可以使用可靠的风险计算模型,如RECODe,来明确其患者的个体心血管和肾脏疾病风险。医患交互式总结临床证据和制订决策有助于患者知晓治疗选择,包括进行共同决策。2型糖尿病人群(全球患病率不断增长1-2)正面临着不断增加的心血管疾病、肾脏病和其他并发症的风险3。数十年来,2型糖尿病的管理始终以控制血糖及糖化血红蛋白(HbA1c)为治疗目标4-5,但是,最近的高质量随机对照研究已经对这种以血糖为中心的治疗模式发起了挑战。研究结果显示,强化血糖控制未必会降低大血管不良事件,它还可能带来不利影响监管机构现在要求新型糖尿病药物必须证明其具有心血管和肾脏获益才能获得批准。对两类新药--钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂(见框图1)的临床试验结果显示,在现有治疗方案(常规治疗)之上加用这些药物,对死亡、心肌梗死、卒中、心力衰竭和肾脏的结局(如进展为终末期肾病)都有获益8-12。 | Sheyu Li Per Olav Vandvik Lyubov Lytvyn Gordon H Guyatt Suetonia C Palmer Rene Rodriguez-Gutierrez Farid Foroutan Thomas Agoritsas Reed A C Siemieniuk Michael Walsh Lawrie Frere David J Tunnicliffe Evi V Nagler Veena Manja Bjφrn Olav Asvold Vivekanand Jha Mieke Vermandere Karim Gariani Qian Zhao Yan Ren Emma Jane Cartwright Patrick Gee Alan Wickes Linda Fems Robin Wright Ling Li Qiukui Hao Reem A Mustafa 无 郭鹤鸣(译) | 2021 | 英国医学杂志中文版2021，24，9： | 7 |
| 3 | 利用铁、铜和硫掺杂TiO_(2)有效光催化转化甲酸显示文摘采用简单的溶胶-凝胶法在TiO_(2)中复合加入铜离子或铁离子和硫酸离子,并研究其甲酸光催化转化效果。通过X射线衍射(XRD)、N_(2)物理吸附(BET比表面积测量)、扫描和透射电子显微镜(SEM和TEM)、UV-Vis漫反射光谱(DRS)和X射线光电子能谱(XPS)对不同光催化剂的结构和形貌进行表征,以确定材料的理化性能与其对甲酸氧化的光催化效率之间的关系。结果显示,添加不同金属离子将导致催化剂之间的重要差异。硫酸化TiO_(2)/Cu(1%Cu)具有最佳的光催化效果,仅在5 min内就可获得100%的甲酸转化率。通过复合添加铜离子和硫酸可使催化剂获得良好的物理化学特性,使其在光催化反应中表现出优越的性能。 | ZOUHEIR Morad TANJI Karim NAVIO Jose Antonio HIDALGO María Carmen JARAMILLO-PAEZ Cesar Augusto KHERBECHE Abdelhak | 2022 | Journal of Central South University2022，29，11： | 3 |
| 4 | Cervical cellulitis and mediastinitis following esophageal perforation:A case report显示文摘Chicken bone is one of the most frequent foreign bodies (FB) associated with upper esophageal perforation. Upper digestive tract penetrating FB may lead to life threatening complications and requires prompt management. We present the case of a 52-year-old man who sustained an upper esophageal perforation associated with cervical cellulitis and mediastinitis. Following CT-scan evidence of FB penetrating the esophagus, the impacted FB was successfully extracted under rigid esophagoscopy. Direct suture was required to close the esophageal perforation. Cervical and mediastinal drainage were made immediately. Naso- gastric tube decompression, broad-spectrum intravenous antibiotics, and parenteral hyperalimentation were administered for 10 d postoperatively. An esophagogram at d 10 revealed no leak at the repair site, and oral alimentation was successfully reinstituted. Conclusion: Rigid endoscope management of FB esophageal penetration is a simple, safe and effective procedure. Primary esophageal repair with drainage of all affected compartments are necessary to avoid life-threatening complications. | Christian A Righini Basilide Z Tea Emile Reyt Karim A Chahine | 2008 | World Journal of Gastroenterology2008，14，9： | 3 |
