Hepatocellular carcinoma(HCC) is one of the commonest malignant tumours in the East. Although the management of HCC in the West is mainly based on the Barcelona Clinic for Liver Cancer staging, it is considered too conservative by Asian countries where the number of HCC patients is huge. Scientific and clinical advances were made in aspects of diagnosis, staging, and treatment of HCC. HCC is well known to be associated with cirrhosis and the treatment of HCC must take into account the presence and stage of chronic liver disease. The major treatment modalities of HCC include:(1) surgical resection;(2) liver transplantation;(3) local ablation therapy;(4) transarterial locoregional treatment; and(5) systemic treatment. Among these, resection, liver transplantation and ablation therapy for small HCC are considered as curative treatment. Portal vein embolisation and the associating liver partition with portal vein ligation for staged hepatectomy may reduce dropout in patients with marginally resectable disease but the midterm and long-term results are still to be confirmed. Patient selection for the best treatment modality is the key to success of treatment of HCC. The purpose of current review is to provide a description of the current advances in diagnosis, staging, preoperative liver function assessment and treatment options for patients with HCC in the east.

BACKGROUND: Hepatectomy is the main curative treatment for hepatocellular carcinoma (HCC), but postoperative long- term survival is poor. Preoperative radiological features of HCC displayed by computed tomography or magnetic resonance imaging could serve as additional prognostic factors. This study aimed to identify preoperative radiological features of HCC that may be of prognostic significance in hepatectomy. METHODS: Ninety-two patients who underwent hepatectomy for HCC were included in this study. Preoperative radiological features including tumor number, size, location (peripheral, middle, central), portal vein invasion, hepatic vein invasion, and presence of pseudo-capsule were analyzed in relation to survival. RESULTS: With a median follow-up period of 41.7 months, the 1-, 3- and 5-year overall survival rates were 85%, 65% and 58%, respectively. Univariate analysis showed that portal vein invasion and absence of pseudo-capsule were significant prognostic factors for overall survival, while all the examined radiological features were prognostic factors for disease-free survival. Multivariate analysis for overall survival found no significant factor. On multivariate analysis for disease-free survival, patients who had tumors with portal vein invasion had poorer survival with a hazard ratio of 2.26 (95% CI, 1.05-4.91; P=0.038) and patients with single nodular HCC or pseudo-capsulated HCC had better survival with a hazard ratio of 0.50 (95% CI, 0.27-0.94; P=0.032) and 0.38 (95% CI, 0.14-0.99; P=0.048), respectively. CONCLUSIONS: Demonstrable pseudo-capsule of HCC and solitary HCC on imaging and absence of portal vein invasionare features associated with better disease-free survival after hepatectomy. These features may guide treatment planning for HCC.

BACKGROUND: Traumatic brain injury(TBI) is associated with most trauma-related deaths. Secondary brain injury is the leading cause of in-hospital deaths after traumatic brain injury. By early prevention and slowing of the initial pathophysiological mechanism of secondary brain injury, prehospital service can signifi cantly reduce case-fatality rates of TBI. In China, the incidence of TBI is increasing and the proportion of severe TBI is much higher than that in other countries. The objective of this paper is to review the pre-hospital management of TBI in *** SOURCES: A literature search was conducted in January 2014 using the China National Knowledge Infrastructure(CNKI). Articles on the assessment and treatment of TBI in pre-hospital settings practiced by Chinese doctors were identified. The information on the assessment and treatment of hypoxemia, hypotension, and brain herniation was extracted from the identifi ed ***: Of the 471 articles identified, 65 met the selection criteria. The existing literature indicated that current practices of pre-hospital TBI management in China were sub-optimal and varied considerably across different ***: Since pre-hospital care is the weakest part of Chinese emergency care, appropriate training programs on pre-hospital TBI management are urgently needed in China.

桂林灯底座装有低压2700K色温的LED灯。光线穿过底部和清澈的山脉,从蚀刻到丙烯酸树脂上的线条反射回来。人们可以改变山脉的方向和位置,以创建一个满足人们审美需求和补充空间的灯光景观。甚至可以巧妙地增加更多的山脉来扩散光线,类似于物理的交互式调光器机制。桂林灯的基座设计为向大自然的宁静致敬,其基座涂有环保涂料,而丙烯酸山本身则由40%的再生塑料制成。将桂林的灯景放在有光泽的反射表面上,使其看上去仿佛坐落在湖后的群山之上。

We examine the effects of the revised Basel II rules on bank managers' discretionary behavior, specifically income smoothing and loan loss provisioning. As the revised rules exert greater regulatory pressure on corporate than retail banking, we predict corporate bank managers to reduce risk-taking activities or increase income smoothing. Analysis of segmental reports reveals greater(less) income smoothing in the corporate banking segments of low-capital(high-capital) banks during the Basel II period, with their managers recognizing loan loss provisions in a less timely fashion. We find no such effects for retail banking. Although we document an initially negative market reaction to the regulatory announcements, that reaction weakens over time. Overall,the study highlights the unintended consequences of the banking rule changes.
