To the Editor : Barcelona Clinic Liver Cancer(BCLC) Stage C hepatocellular carcinoma(HCC) with vascular invasion has been considered unresectable. however, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced HCC who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant HCC in right liver lobe with inferior vena cava(IVC) invasion.

虽然已经进行了多次大规模的全基因组关联研究（genome—wide association studies，GWAs），但是仅少数研究成功地鉴定出能重复的、重要的高血压基因位点，而且在中国人中进行的相关研究更少。与迟发性高血压相比，青少年高血压（young—onset hypertension，YOH）被认为是更有希望治疗的疾病，因为其受到遗传因素的影响更大。

BACKGROUND: Emergency departments(EDs) face problems with overcrowding, access block, cost containment, and increasing demand from patients. In order to resolve these problems, there is rising interest to an approach called "lean" management. This study aims to(1) evaluate the current patient flow in ED,(2) to identify and eliminate the non-valued added process, and(3) to modify the existing ***: It was a quantitative, pre- and post-lean design study with a series of lean management work implemented to improve the admission and blood result waiting time. These included structured re-design process, priority admission triage(PAT) program, enhanced communication with medical department, and use of new high sensitivity troponin-T(hsTnT) blood test. Triage waiting time, consultation waiting time, blood result time, admission waiting time, total processing time and ED length of stay were ***: Among all the processes carried out in ED, the most time consuming processes were to wait for an admission bed(38.24 minutes; SD 66.35) and blood testing result(mean 52.73 minutes, SD 24.03). The triage waiting time and end waiting time for consultation were significantly decreased. The admission waiting time of emergency medical ward(EMW) was significantly decreased from 54.76 minutes to 24.45 minutes after implementation of PAT program(P<0.05).CONCLUSION: The application of lean management can improve the patient flow in ED. Acquiescence to the principle of lean is crucial to enhance high quality emergency care and patient satisfaction.

中韩两国姓氏制度的产生、变化、发展都基于"我"和"你"区分的"排他性"。但是,中国宋以后籍贯和姓氏一起使用的习惯演变为一种"社会的制度",而韩国朝鲜后期以后将世居地和姓氏一起使用的习惯并不是一种"社会的制度",而是一个"惯习"的继续。这与古代中韩两国社会性格的差异有着密切关系。
