| 1 | 采用动态推-拉技术增强动脉瘤分流器的导流作用:一项实验和模型研究显示文摘目的 神经血管分流器是治疗颅内动脉瘤的一种有弹性的、纵横交错的网状支架。本研究采用动态推-拉技术调节动脉瘤瘤口分流器的网格密度,以便最大化其导流作用。通过自主研发的高保真虚拟支架计算机模型技术联合计算机流体动力学,探讨动态推-拉技术对特定动脉瘤病人血流动力学的影响。方法采用动态推-拉技术和不同长度的传送导线,将两个Pipeline分流器放置到两个相同侧壁的大脑前动脉动脉瘤模型中。然后数字模拟操作过程,并验证模拟的网格几何结构。通过调节放置在侧壁动脉瘤和基底动脉主干梭形动脉瘤(前期已放置分流器)的分流器,采用计算机流体动力学分析,评估血流动力学的具体变化。同时评估来源于临床病例样本的分流器网格的影像。 | Ma D Xiang J Choi H 周静 郭玉慧 | 2014 | 中国微侵袭神经外科杂志2014，19，6： | 12 |
| 2 | 原发灶切除在无症状的、同时性的、转移灶不可切除的结直肠癌患者中的作用:一项多中心随机对照试验显示文摘目的:我们在同时性的、转移灶不可切除的无症状Ⅳ期结直肠癌患者中,评估接受原发灶切除术(primary tumor resection,PTR)续贯化疗的患者相比接受单纯化疗的患者的生存优势。方法:这是一项开放的前瞻性随机对照试验(ClnicalTrials.gov注册号:NCT01978249)。从2013年5月至2016年4月,在12所三级医院中将48例诊断为转移灶不可切除的、原发灶无症状的结直肠癌患者按1:1比例进行随机化分组,其中PTR组26例、化疗组22例。主要终点是两年总生存率,次要终点为与原发灶、PTR相关的并发症发生率以及转变为可切除状态的转化率。 | 卓长华 陈功 PARK E J BAEK J H CHOI G S | 2020 | 结直肠肛门外科2020，26，5： | 8 |
| 3 | Features of extrahepatic metastasis after radiofrequency ablation for hepatocellular carcinoma显示文摘BACKGROUND Extrahepatic metastasis(EHM)of hepatocellular carcinoma(HCC)is associated with poor outcomes.However,the clinical features and risk factors of EHM of HCC after radiofrequency ablation(RFA)remain unclear.AIM To elucidate the characteristics and risk factors of EHM after RFA for HCC.METHODS From January 2008 to December 2017,we retrospectively enrolled 661 patients who underwent RFA as first-line treatment for HCC at 2 tertiary hospitals.The inclusion criteria were age≥18 years,a diagnosis of HCC,and treatment-naivety.Abdominal computed tomography(CT)or magnetic resonance imaging(MRI)and alpha-fetoprotein measurements were routinely performed at 1 mo after RFA and followed-up at intervals of 3-6 mo.Univariate analyses were performed using the chi-squared test or Student’s t-test,and univariate and multivariate analyses were performed via logistic regression,as appropriate.RESULTS EHM was diagnosed in 44 patients(6.7%)during a median follow-up period of 1204 days.The 10-year cumulative rate of HCC recurrence and EHM was 92.7%and 33.7%,respectively.Initial recurrence was most often intrahepatic,and the rate of extrahepatic recurrence at initial recurrence was only 1.2%.The median time to the diagnosis of EHM was 2.68 years,and 68.2%of patients developed EHM within 2 years of the first recurrence,regardless of recurrence-free survival and 75.0%of patients developed EHM within 5 years after first recurrence.EHM was mostly diagnosed via abdominal CT/MRI in 33(75.0%)and 38 of 44 patients(86.4%)with EHM had either positive abdominal CT scan results or serum AFP level elevation.In multivariate analysis,recurrence-free survival<2 years,ablation zone/tumor size<2,and alpha-fetoprotein level>400 IU/mL were associated with a high EHM risk.CONCLUSION EHM occurs following multiple intrahepatic recurrences after RFA and combined contrast-enhanced abdominal CT and serum AFP were useful for surveillance.Patients especially with high-risk factors require close follow-up for EHM. | Jae H Yoon Young J Goo Chae-Jun Lim Sung K Choi Sung B Cho Sang S Shin Chung H Jun | 2020 | World Journal of Gastroenterology2020，26，32： | 3 |
| 4 | Tracking domestic ducks:A novel approach for documenting poultry market chains in the context of avian influenza transmission显示文摘Agro-ecological conditions associated with the spread and persistence of highly pathogenic avian influenza(HPAI) are not well understood, but the trade of live poultry is suspected to be a major pathway. Although market chains of live bird trade have been studied through indirect means including interviews and questionnaires, direct methods have not been used to identify movements of individual poultry. To bridge the knowledge gap on quantitative movement and transportation of poultry, we introduced a novel approach for applying telemetry to document domestic duck movements from source farms at Poyang Lake, China. We deployed recently developed transmitters that record Global Positioning System(GPS) locations and send them through the Groupe Spécial Mobile(GSM) cellular telephone system. For the first time, we were able to track individually marked ducks from 3 to 396 km from their origin to other farms, distribution facilities, or live bird markets. Our proof of concept test showed that the use of GPS-GSM transmitters may provide direct, quantitative information to document the movement of poultry and reveal their market chains. Our findings provide an initial indication of the complexity of source-market network connectivity and highlight the great potential for futuretelemetry studies in poultry network analyses. | Chang-Yong Choi John Y Takekawa XIONG Yue LIU Ying Martin Wikelski George Heine Diann J Prosser Scott H Newman John Edwards Fusheng Guo Xiangming Xiao | 2016 | Journal of Integrative Agriculture2016，15，7： | 3 |
