1Minimally invasive surgery for gastric cancer: A comparison between robotic, laparoscopic and open surgery显示文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery.Amilcare Parisi Daniel Reim Felice Borghi Ninh T Nguyen Feng Qi Andrea Coratti Fabio Cianchi Maurizio Cesari Francesca Bazzocchi Orhan Alimoglu Johan Gagnière Graziano Pernazza Simone D'Imporzano Yan-Bing Zhou Juan-Santiago Azagra Olivier Facy Steven T Brower Zhi-Wei Jiang Lu Zang Arda Isik Alessandro Gemini Stefano Trastulli Alexander Novotny Alessandra Marano Tong Liu Mario Annecchiarico Benedetta Badii Giacomo Arcuri Andrea Avanzolini Metin Leblebici Denis Pezet Shou-Gen Cao Martine Goergen Shu Zhang Giorgio Palazzini Vito D'Andrea Jacopo Desiderio 2017World Journal of Gastroenterology2017,23,13:17

3Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li 2014World Journal of Gastrointestinal Pathophysiology2014,5,4:13
4Risk stratification for ST segment elevation myocardial infarction in the era of primary percutaneous coronary intervention显示文摘Acute coronary syndromes presenting with ST elevation are usually treated with emergency reperfusion/revascularisation therapy. In contrast current evidence and national guidelines recommend risk stratification for non ST segment elevation myocardial infarction(NSTEMI) with the decision on revascularisation dependent on perceived clinical risk. Risk stratification for STEMI has no recommendation. Statistical risk scoring techniques in NSTEMI have been demonstrated to improve outcomes however their uptake has been poor perhaps due to questions over their discrimination and concern for application to individuals who may not have been adequately represented in clinical trials. STEMI is perceived to carry sufficient risk to warrant emergency coronary intervention [by primary percutaneous coronary intervention(PPCI)] even if this results in a delay to reperfusion with immediate thrombolysis. Immediate thrombolysis may be as effective in patients presenting early, or at low risk, but physicians are poor at assessing clinical and procedural risks and currently are not required to consider this. Inadequate data on risk stratification in STEMI inhibits the option of immediate fibrinolysis, which may be cost-effective. Currently the mode of reperfusion for STEMI defaults to emergency angiography and percutaneous coronary intervention ignoring alternative strategies. This review article examines the current risk scores and evidence base for risk stratification for STEMI patients. The requirements for an ideal STEMI risk score are discussed.Richard A Brogan Christopher J Malkin Philip D Batin Alexander D Simms James M McLenachan Christopher P Gale 2014World Journal of Cardiology2014,6,8:6
5纤维母细胞生长因子对复合皮肤移植成活和收缩的影响显示文摘我们曾报道应用同基因表层皮片(IE)和同种异基因真皮(AD)组成复合皮肤移植物(CSG)可一次完成全层皮肤缺损的永久性修复。但由于IE不能及时获得足够血运,IE常有部分坏死,CSG后期收缩仍较明显。在本研究中我们进一步用纤维母细胞生长因子(FGF)预先处理AD获得较好效果。经观察17周表明,FGF组皮片坏死率和坏死面积较对照组明显下降(P<0.05);FGF组CSG收缩较对照组明显减轻(P<0.001);皮片坏死面积与皮片最终面积呈负相关(r=-0.450,P<0.05)。实验预示,完全成活的CSG后期收缩较移植同等厚度的IE为轻。观察2年,AD未被排斥。方承辉 Robb E C 于光曙 Alexander J W Warden G D 1993中华整形烧伤外科杂志1993,9,1:6
6Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
7Nutritional and health benefits of semi-elemental diets: A comprehensive summary of the literature显示文摘AIM:To critically review and summarize the literature on nutritional and health outcomes of semi-elemental formulations on various nutritionally vulnerable patient populations who are unable to achieve adequate nutrition from standard oral diets.METHODS:We conducted a comprehensive literature search of Pubmed and Embase databases.We manually screened articles that examined nutritional and health outcomes(e.g.,growth,disease activity,gastrointestinal impairment,mortality,and economic impact)among various patient groups receiving semi-elemental diets.This review focused on full-text articles of randomized controlled clinical trials and other intervention studies,but pertinent abstracts and case studies were also included.Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population in this systematic review.RESULTS:Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population.The efficacy of semi-elemental whey hydrolyzed protein(WHP)diet have been reported in various nutritionally high risk patient populations including-Crohn’s disease,short bowel syndrome,acute and chronic pancreatitis,cerebral palsy,cystic fibrosis,cerebrovascular accidents,human immunodeficiency virus,critically ill,and geriatrics.Collectively,the evidence from the medical literature indicates that feeding with a semi-elemental diet performs as well or better than parenteral or amino acid based diets in terms of toler-ance,digestion,and nutrient assimilation measures across various disease conditions.CONCLUSION:Based on this comprehensive review of the literature,patient populations who have difficulty digesting or absorbing standard diets may be able to achieve improved health and nutritional outcomes through the use of semi-elemental WHP diets.Dominik D Alexander Lauren C Bylsma Laura Elkayam Douglas L Nguyen 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,2:3
8Revisiting normal perfusion pressure breakthrough in light of hemorrhage-induced vasospasm显示文摘Cerebral arteriovenous malformations(AVMs) have abnormally enlarged arteries and veins prone to spontaneous hemorrhage.Immediately following surgical excision of a cerebral AVM,even normal brain tissue surrounding the lesion is subject to hemorrhage,a phenomenon termed normal perfusion pressure breakthrough(NPPB) syndrome.According to this theory,arteries supplying cerebral AVMs become dilated and lose their capacity to dilate or constrict to autoregulate pressure.Acutely after removal of a cerebral AVM,excessive blood pressure in these arterial feeders can cause normal brain tissue to bleed.However,this theory remains controversial.We present a patient with a cerebral AVM that demonstrated cerebrovascular reactivity and argues against an assumption underlying the theory of NPPB syndrome.Matthew D Alexander E Sander Connolly Philip M Meyers 2010World Journal of Radiology2010,2,6:3
9Unique Marine Olenekian-Anisian Boundary Section from South Primorye, Russian Far East显示文摘To show paleontological characteristics of the Olenekian-Anisian boundary beds in the Russian Far East, a review of new data on the Upper Olenekian and Lower Anisian biostratigraphy of South Primorye is given on the basis of five sections: Golyi Cape, Petrovka River, Zhitkov Peninsula, Tchernyschew Bay and Atlasov Cape, using new ammonoid, brachiopod and conodont findings. The most representative ammonoid assemblage at the base of the Anisian was discovered in the Ussuriphyllites amurensis Zone (10.6 m thick) of the Atlasov Cape Section: Parasageceras sp. nov., Prionitidae gen. et sp. nov., Ussuriphyllites amurensis (Kiparisova) (dominant), Megaphyllites atlasoviensis Zakharov, Leiophyllites praematurus Kiparisova, Leiophyllites sp., Ussurites sp., Paradanubites sp. indet., Paracrochordiceras sp. nov., Prohungarites popowi Kiparisova, Arctohungarites primoriensis Zakharov, A. solimani (Toula), Salterites sp. indet. (gigantic shell), and Tropigastrites sublachontanus Zakharov. Conodonts Neospathodus cf. homeri (Bender) were found in the lower part of the Ussuriphyllites amurensis Zone of the Atlasov Cape. The Atlasov Cape seems to be one of the very promising sections of the Russian Far East for detailed investigation of the Olenekian-Anisian boundary.Yuri D Zakharov Alexander M Popov Galina I Buryi 2005Journal of China University of Geosciences2005,16,3:3

11使用二甲双胍的禁忌证 证据显示应该修改二甲双胍的禁忌证显示文摘在英国前瞻性糖尿病研究(UNPOS)中,2型糖尿病患者被随机分入二甲双胍、磺酰脲类或胰岛素强化治疗组,3组患者取得了相似的血糖控制效果,微血管并发症终点事件显著降低。该项研究显示,肥胖患者使用二甲双胍治疗可以降低心血管事件的发生,二甲双胍治疗组的患者没有低血糖事件。G C Jones J P Macklin W D Alexander 李玉秀 2003英国医学杂志中文版2003,6,3:2
12Nitrogen and Carbon Isotope Data of Olenekian to Anisian Deposits from Kamenushka/South Primorye, Far-Eastern Russia and Their Palaeoenvironmental Significance显示文摘The Kamenushka Formation, exposed in the northern part of South Primorye(Kamenushka-1 and Kamenushka-2 sections), is one of the few localities in the world with richly fossiliferous Lower–Upper Olenekian sedimentary successions. Lower to Middle Triassic ammonoid-, brachiopod-and conodont-bearing silty-clayey deposits of the Kamenushka-1 and Kamenushka-2 sections have been isotope-geochemically investigated in detail. As a result, these sections, together with the previously investigated Abrek Section, exposed in the southern part of South Primorye, provide almost complete 15 Norg-and 13 Corg-records for the Lower Triassic of this region. Nine Nisotope intervals and the five negative C-isotope excursions, reflecting, apparently, unstable climatic and hydrological conditions, have been distinguished in the Lower Triassic of South Primorye. On the basis of the new C-isotope data the Mesohedenstroemia bosphorensis Zone(upper part), Shimanskyites shimanskyi and Neocolumbites insignis zones of South Primorye are correlated now with the Lower Smithian part of the Yinkeng Formation, the Upper Smithian part of the Helongshan Formation and the Middle Spathian part of the Nanlinghu Formation in South China, respectively, as has been observed in the Abrek, Kamenushka-2, West Pingdingshan and Majiashan sections.Yuri D Zakharov Micha Horacek Alexander M Popov Liana G Bondarenko 2018Journal of Earth Science2018,29,4:2
13Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:2
