| 1 | Lymph node ratio and preoperative CA 19-9 levels predict overall survival and recurrence-free survival in patients with resected pancreatic adenocarcinoma显示文摘AIM:Clinicopathologic factors predicting overall survival (OS) would help identify a subset to benefit from adjuvant therapy. METHODS: One hundred and sixty-nine patients patients from 1984 to 2009 with curative resections for pancreatic adenocarcinoma were included. Tumors were staged by American Joint Committee on Cancer 7th edition criteria. Univariate and multivariable analyses were performed using Kaplan-Meier methodology or Cox proportional hazard models. Log-rank tests were performed. Statistical inferences were assessed by two-sided 5% significance level. RESULTS: Median age was 67.1 (57.2-73.0) years with equal gender distribution. Tumors were in the head (89.3%) or body/tail (10.7%). On univariate analysis, adjuvant therapy, lymph node (LN) ratio, histologic grade, negative margin status, absence of peripancreatic extension, and T stage were associated with improved OS. Adjuvant therapy, LN ratio, histologic grade, number of nodes examined, negative LN status, and absence of peripancreatic extension were associated with improved recurrence-free survival (RFS). On multivariable analysis, LN ratio and carbohydrate antigen (CA) 19-9 levels were associated with OS. LN ratio was associated with RFS. CONCLUSION: The LN ratio and CA 19-9 levels are independent prognostic factors following curative resections of pancreatic cancer. | Sabrina C Wentz Zhi-Guo Zhao Yu Shyr Chan-Juan Shi Kay Washington Nipun B Merchant Fen Xia A Bapsi Chakravarthy | 2012 | World Journal of Gastrointestinal Oncology2012，4，10： | 3 |

| 6 | 私募股权投资在美国页岩气基础设施建设中的新角色显示文摘页岩气已经成为美国能源结构中的重要组成部分。在不断发展的美国页岩气领域,高峰产量与气体收集和处理设施、管道的计划能力之间存在巨大差距,凸显了额外投资的必要性。页岩气资源的大规模开发已经吸引了许多建设中游设施的投资,但投资来源非常分散,基础设施建设缺乏统一的规划和协调。三类主要的基础设施建设投资来源是独立勘探开发公司、中游的业主有限合伙企业(MLP)和私募股权基金支持的中游公司。当前,由私募股权基金支持的业主有限合伙企业正成为基础设施投资的中坚。 | Chuck Chakravarthy Rachael Goydan Meltem Demirors 黄佳音 | 2010 | 国际石油经济2010，18，8： | 2 |
| 7 | 高位胸段硬膜外麻醉下清醒病人的冠状动脉搭桥手术显示文摘目的 了解在高位胸段硬膜外麻醉下避免全麻行非体外循环心脏跳动下冠状动脉搭桥手术的可行性。方法 硬膜外麻醉下对 2 5例清醒病人行非体外循环心脏跳动下冠状动脉搭桥手术 ,没有气管插管全麻 ,所有病人在手术前晚行硬膜外置管。结果 总共搭桥 71支 (1支 11例 ,2支 5例 ,3支 6例 ,4支 3例 )。除 1例因为术中出现室颤转为全麻和体外循环外 ,2 4例在硬外麻作为唯一麻醉下完成非体外循环心脏跳动下冠状动脉搭桥手术。除 2例行左胸小切口外其余行正中切口 ;其中 6例为再次手术 ;平均每例搭桥2 8支 ,没有手术死亡。术后在复苏室和病房住院时间分别为 (16 2± 4 2 )h和 (3 2 4± 1 2 )d。结论 本组的早期经验提示在没有气管插管全麻。 | 郭惠明 Murali Chakravarthy Vivek Jawali TA Patil K Jayaprakash NV Shivananda | 2003 | 岭南心血管病杂志2003，9，4： | 2 |
