| 1 | Percutaneous left atrial appendage closure:Technical aspects and prevention of periprocedural complications with the watchman device显示文摘Transcatheter closure of the left atrial appendage has been developed as an alternative to chronic oral anticoagulation for stroke prevention in patients with atrial fibrillation, and as a primary therapy for patients with contraindications to chronic oral anticoagulation. The promise of this new intervention compared with warfarin has been supported by several, small studies and two pivotal randomized trial with the Watchman Device. The results regarding risk reduction for stroke have been favourable although acute complications were not infrequent. Procedural complications, which are mainly related to transseptal puncture and device implantation, include air embolism, pericardial effusions/tamponade and device embolization. Knowledge of nature, management and prevention of complications should minimize the risk of complications and allow transcatheter left atrial appendage closure to emerge as a therapeutic option for patients with atrial fibrillation at risk for cardioembolic stroke. | Sven M bius-Winkler Nicolas Majunke Marcus Sandri Norman Mangner Axel Linke Gregg W Stone Ingo D hnert Gerhard Schuler Peter B Sick | 2015 | World Journal of Cardiology2015，7，2： | 14 |
| 2 | Global kinematics of tectonic plates and subduction zones since the late Paleozoic Era显示文摘Detailed global plate motion models that provide a continuous description of plate boundaries through time are an effective tool for exploring processes both at and below the Earth's surface. A new generation of numerical models of mantle dynamics pre-and post-Pangea timeframes requires global kinematic descriptions with full plate reconstructions extending into the Paleozoic(410 Ma). Current plate models that cover Paleozoic times are characterised by large plate speeds and trench migration rates because they assume that lowermost mantle structures are rigid and fixed through time. When used as a surface boundary constraint in geodynamic models, these plate reconstructions do not accurately reproduce the present-day structure of the lowermost mantle. Building upon previous work, we present a global plate motion model with continuously closing plate boundaries ranging from the early Devonian at 410 Ma to present day.We analyse the model in terms of surface kinematics and predicted lower mantle structure. The magnitude of global plate speeds has been greatly reduced in our reconstruction by modifying the evolution of the synthetic Panthalassa oceanic plates, implementing a Paleozoic reference frame independent of any geodynamic assumptions, and implementing revised models for the Paleozoic evolution of North and South China and the closure of the Rheic Ocean. Paleozoic(410-250 Ma) RMS plate speeds are on average ~8 cm/yr, which is comparable to Mesozoic-Cenozoic rates of ~6 cm/yr on average.Paleozoic global median values of trench migration trend from higher speeds(~2.5 cm/yr) in the late Devonian to rates closer to 0 cm/yr at the end of the Permian(~250 Ma), and during the Mesozoic-Cenozoic(250-0 Ma) generally cluster tightly around ~1.1 cm/yr. Plate motions are best constrained over the past 130 Myr and calculations of global trench convergence rates over this period indicate median rates range between 3.2 cm/yr and 12.4 cm/yr with a present day median rate estimated at~5 cm/yr. For Paleozoic times(410-251 Ma) our model results in median convergence rates largely~5 cm/yr. Globally,~90% of subduction zones modelled in our reconstruction are determined to be in a convergent regime for the period of 120-0 Ma. Over the full span of the model, from 410 Ma to 0 Ma,~93% of subduction zones are calculated to be convergent, and at least 85% of subduction zones are converging for 97% of modelled times. Our changes improve global plate and trench kinematics since the late Paleozoic and our reconstructions of the lowermost mantle structure challenge the proposed fixity of lower mantle structures, suggesting that the eastern margin of the African LLSVP margin has moved by as much as ~1450 km since late Permian times(260 Ma). The model of the plate-mantle system we present suggests that during the Permian Period, South China was proximal to the eastern margin of the African LLSVP and not the western margin of the Pacific LLSVP as previous thought. | Alexander Young Nicolas Flament Kayla Maloney Simon Williams Kara Matthews Sabin Zahirovic R.Dietmar Müller | 2019 | Geoscience Frontiers2019，10，3： | 10 |
| 3 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021，24，8： | 7 |

| 5 | Liver biochemistry profile,significance and endoscopic management of biliary tract complications post orthotopic liver transplantation显示文摘AIM: To correlate the significance of liver biochemical tests in diagnosing post orthotopic liver transplantation (OLT) biliary complications and to study their profile before and after endoscopic therapy. METHODS: Patients who developed biliary complications were analysed in detail for the clinical information,laboratory tests,treatment offered,response to it,follow up and outcomes. The profile of liver enzymes was determined. The safety,efficacy and outcomes of endoscopic retrograde cholangiography (ERC) were also analysed. RESULTS: 40 patients required ERC for 70 biliary complications. GGT was found to be > 3 times (388.1 ± 70.9 U/mL vs 168.5 ± 34.2 U/L,P = 0.007) and SAP > 2 times (345.1 ± 59.1 U/L vs 152.7 ± 21.4 U/L,P = 0.003) the immediate post OLT values. Most frequent complication was isolated anastomotic strictures in 28 (40%). Sustained success was achieved in 26 (81%) patients. CONCLUSION: Biliary complications still remain an important problem post OLT. SAP and GGT can be used as early,non-invasive markers for diagnosis and also to assess the adequacy of therapy. Endoscopic management is usually effective in treating the majority of these biliary complications. | Yogesh M Shastri Nicolas M Hoepffner Bora Akoglu Christina Zapletal Wolf O Bechstein Wolfgang F Caspary Dominik Faust | 2007 | World Journal of Gastroenterology2007，13，20： | 6 |

| 7 | Procalcitonin,and cytokines document a dynamic inflammatory state in non-infected cirrhotic patients with ascites显示文摘AIM:To quantitate the simultaneous serum and ascitic fluid levels of procalcitonin and inflammatory markers in cirrhotics with and without ascites.METHODS:A total of 88 consecutive severe cirrhotic patients seen in a large city hospital liver clinic were studied and divided into two groups,those with and without ascites.Group 1 consisted of 41 cirrhotic patients with massive ascites,as demonstrated by necessity for therapeutic large-volume paracentesis.Group 2consisted of 47 cirrhotic patients without any clinically documented ascites to include either a recent abdominal computed tomography scan or ultrasound study.Serum and ascitic fluid levels of an array of inflammatory markers,including procalcitonin,were measured and compared to each other and a normal plasma panel(NPP).RESULTS:The values for inflammatory markers assayed in the serum of Groups 1 and 2,and ascitic fluid of the Group 1.The plasma levels of the inflammatory cytokines interleukin(IL)-2,IL-4,IL-6,IL-8,interferon gamma(IFNγ)and epidermal growth factor(EGF)were all significantly greater in the serum of Group 1as compared to that of the serum obtained from the Group 2 subjects(all P<0.05).There were significantly greater serum levels of IL-6,IL-8,IL-10,monocyte chemoattractant protein-1,tumor necrosis factor-α,vascular endothelial growth factor and EGF when comparing Group 2 to the NPP.There was no significant difference for IL-1A,IL-1B,IL-2,IL-4 and IFNγlevels between these two groups.Serum procalcitonin levels were increased in cirrhotics with ascites compared to cirrhotics without ascites,but serum levels were similar to ascites levels within the ascites group.Furthermore,many of these cytokines,but not procalcitonin,demonstrate an ascites-to-serum gradient.Serum procalcitonin does not demonstrate any significant difference segregated by liver etiology in the ascites group;but ascitic fluid procalcitonin is elevated significantly in car-diac cirrhosis/miscellaneous subgroup compared to the hepatitis C virus and alcoholic cirrhosis subgroups.CONCLUSION:Procalcitonin in the ascitic fluid,but not in the serum,differentiates between cirrhotic subgroup reflecting the dynamic interplay of ascites,bacterial translocation and the peri-peritoneal cytokine. | Bashar M Attar Christopher M Moore Magdalena George Nicolae Ion-Nedelcu Rafael Turbay Annamma Zachariah Guiliano Ramadori Jawed Fareed David H Van Thiel | 2014 | World Journal of Gastroenterology2014，20，9： | 4 |

| 10 | Targeting head and neck tumoral stem cells: From biologicalaspects to therapeutic perspectives显示文摘Head and neck squamous cell cancer(HNSCC) is the sixth most common cancer in the world. Effective therapeutic modalities such as surgery, radiation, chemotherapy and combinations of each are used in the management of the disease. In most cases, treatment fails to obtain total cancer cure. In recent years, it appears that one of the key determinants of treatment failure may be the presence of cancer stem cells(CSCs) that escape currently available therapies. CSCs form a small portion of the total tumor burden but may play a disproportionately important role in determining outcomes. CSCs have stem features such as self-renewal, high migration capacity, drug resistance, high proliferation abilities. A large body of evidence points to the fact that CSCs are particularly resistant to radiotherapy and chemotherapy. In HNSCC, CSCs have been increasingly shown to have an integral role in tumor initiation, disease progression, metastasis and treatment resistance. In the light of such observations, the present review summarizes biological characteristics of CSCs in HNSCC, outlines targeted strategies for the successful eradication of CSCs in HNSCC including targeting the self-renewal controlling pathways, blocking epithelial mesenchymal transition, niche targeting, immunotherapy approaches and highlights the need to better understand CSCs biology for new treatments modalities. | Benoîte Méry Jean-Baptiste Guy Sophie Espenel Anne-Sophie Wozny Stéphanie Simonet Alexis Vallard Gersende Alphonse Dominique Ardail Claire Rodriguez-Lafrasse Nicolas Magné | 2016 | World Journal of Stem Cells2016，8，1： | 3 |

| 12 | Disease dependent qualitative and quantitative differences in the inflammatory response to ascites occurring in cirrhotics显示文摘AIM:To assess differing patterns and levels of ascitic fluid cyctokine and growth factors exist between those with a high risk and low risk of spontaneous bacterial peritonitis(SBP). METHODS: A total of 57 consecutive patients with ascites requiring a large volume paracentesis were studied. Their age, gender, specific underlying disease conditions were recorded after a review of their clinical records. Each underwent a routine assessment prior to their paracentesis consisting of a complete blood count, complete metabolic profile and prothrombin time/international normalized ratio(INR) determination. The ascitic fluid was cultured and a complete cellcount and albumin determination was obtained on the fluid. In addition, blood and ascitic fluid was assessed for the levels of interleukin interleukin(IL)-1A, IL-1B, IL-2, IL-4, IL-8, IL-10, monocyte chemotactic protein(MCP)-1, tumor necrosis factor(TNF)-α, interferon(IFN)-γ, vascular endothelial growth factor(VEGF) and epidermal growth factor(EGF) utilizing the Randox Biochip platforms(Boston, MA). A serum-ascites gradient, for each cytokine and growth factor was calculated. The results are reported as mean ± SEM between disease groups with statistical analysis consisting of the student t-test(two tailed) with a P value of 0.05 defining significance. RESULTS: No clinically important demographic or biochemical differences between the 4 groups studied were evident. In contrast, marked difference in the cytokine and growth factors levels and pattern were evident between the 4 disease groups. Individuals with alcoholic cirrhosis had the highest levels of IL-1A, IL-1B, IL-4, IFNγ. Those with malignant disease had the highest levels of IL-2. Those with hepatitis C virus(HCV) associated cirrhosis had the highest value for IL-6, IL-8, IL-10, MCP-1 and VEGF. Those with cardiac disease had the highest level of TNF-α and EGF. The calculated serum- ascites gradients for the cardiac and malignant disease groups had a greater frequency of negative values signifying greater levels of IL-8, IL-10 and MCP-1 in ascites than did those with alcohol or HCV disease. CONCLUSION: These data document important differences in the cytokine and growth factor levels in plasma, ascitic fluid and the calculated plasma- ascites fluid gradients in cirrhotics requiring a large volume paracentesis. These differences may be important in determining the risk for bacterial peritonitis. | Bashar M Attar Magdalena George Nicolae Ion-Nedelcu Guilliano Ramadori David H Van Thiel | 2014 | World Journal of Hepatology2014，6，2： | 3 |
| 13 | Spontaneous bacterial peritonitis prevalence in pretransplant patients and its effect on survival and graft loss post-transplant显示文摘AIM To investigate the incidence of spontaneous bacterial peritonitis(SBP) in pre-transplant patients and its effect on post transplant mortality and graft failure. METHODS We conducted a retrospective cohort study of patient records from the organ procurement and transplant network data set. Patients were identified by the presence of SBP pre-transplant. Univariate post-transplant survival models were constructed using the Kaplan-Meier technique and multivariate models were constructed using the Cox proportional hazards model. Variables that affected post-transplant graft survival were identified in the SBP population. RESULTS Forty-seven thousand eight hundred and eighty patient records were included in the analysis for both groups, and 1966(4.11%) patients were identified in the data set as having pre-transplant SBP. Patients that had pre-transplant SBP had higher rates of graft loss from recurrent hepatitis C virus(HCV)(3.6% vs 2.0%, P < 0.0001), infections leading to graft loss(1.9% vs 1.3%, P = 0.02), primary non-function(4.3% vs 3.0%, P < 0.0001) and chronic rejection(1.1% vs 0.7%, P = 0.04). Kaplan-Meier survival analysis showed a statistically significant difference in all-cause survival in patients with a history of SBP vs those without(P < 0.0001). Pretransplant history of SBP was independently predictiveof mortality due to recurrent HCV(HR = 1.11, 95%CI: 1.02-1.21, P < 0.017) after liver transplantation.CONCLUSION HCV patients prior to the advent of directing acting anti-viral agents had a higher incidence of pre-transplant SBP than other patients on the liver transplant wait list. SBP history pre-transplant resulted in a higher rate of graft loss due to recurrent HCV infection and chronic rejection. | Neeral L Shah Nicolas M Intagliata Zachary H Henry Curtis K Argo Patrick G Northup | 2016 | World Journal of Hepatology2016，8，36： | 2 |
