The treatment of HCC is complex and complicated by the severity of associated chronic liver disease, the stage of HCC, and the clinical condition of the patient. Liver resection(LR) is one of the most efficient treatments for patients with HCC, with an expected 5-year survival of 38%-61% depending on the stage of the disease. Improved liver function assessment, increased understanding of segmental liver anatomy from advanced imaging studies, and surgical technical progress are important factors that have led to reduced mortality in patients with HCC. The indication for LR may be expanded due to emerging evidences from laparoscopic hepatectomies and combined treatments with newly developed chemotherapies. Liver transplantation(LT) is considered as an ideal treatment for removal of existing tumors and the injured/preneoplastic underlying liver tissue with impaired liver function and the risk of multicentric carcinogenesis that results from chronically injured liver. However, LT is restricted to patients with minimal risk of tumor recurrence under immunosuppression. The expansion of criteria for LT in HCC patients is still under trial and discussion. Limited availability of grafts, as well as the risk and the cost of transplantation have led to considerable interest in expansion of the donor pool, living donor-related transplantation, and combined treatment involving LR and LT. This highlight presents evidence concerning recent studies evaluating LR and LT in HCC patients. In addition, alternative therapies for the treatment of early stage tumors and the management of patients on transplant waiting lists are discussed.展开更多

The administrative distributed platform is integrated with BeiDou positioning and multiple communication ways so as to achieve main disaster reduction application services, including disaster information acquisition and monitoring, emergency relief for trapped people, on-site emergency relief command service, relief supplies＇ transportation monitoring, and disaster information publishing service. By the platform, serious disaster information reporting time may be reduced to one hour and the emergency decision-making information service for serious natural disasters can be effectively improved, and it will be helpful to provide technical references for the industrial application and promotion of BeiDou inte- grated disaster reduction.展开更多

The proposed system provides the required home energy by installing renewable energy and storage devices. It also manages and schedules the power flow during peak and off-peak periods. In addition, a two-way communication protocol is developed to enable the home owners and the utility service provider to improve the energy flow and the consumption efficiency. The system can be an integral part for homes in a smart grid or smart microgrid power networks. A prototype for the proposed system was designed, implemented and tested by using a controlled load bank to simulate a scaled random real house consumption behavior. Three different scenarios were tested and the results and findings are reported. Moreover, data flow security among the home, home owners and utility server is developed to minimize cyber-attaeks.展开更多

According to scientific analysis of the lowcarbon economy, we can divide low-carbon management measures into three parts： measures for reduction of carbon sources, carbon flow planning, and increase of carbon sinks. Furthermore, we list the advantages that China can utilize to develop its own low-carbon management measures. In the end, necessary adjustments to environmental management measures in China can be made according to this scientific classification.展开更多
