Liver transplantation represents a cornerstone in the management of early-stage hepatocellular carcinoma (HCC). Expansion beyond the Milan criteria for liver transplantation (1 lesion <or= 5 cm, or 2 to 3 lesions each <or= 3 cm) remains controversial. This review covers several key areas: (1) Recent developments and published data on expanded criteria for(More)
—Originally developed for secure communications in military applications, frequency hopping systems possess anti-jamming and anti-interception features by exploiting time-frequency diversity over large spectrum. However, the spectral efficiency of existing FH systems is very low due to inappropriate use of the total available bandwidth. To improve the(More)
Historically developed for secure communication and military use, CDMA has been identified as a major modulation and multiple-access technique for 3G systems and beyond. In addition to the wide bandwidth and low power-spectrum density which make CDMA signals robust to narrowband jamming and easy to be concealed within the noise floor, the physical layer(More)
BACKGROUND The search for a strategy to provide temporary liver support and salvage the patients with acute-on-chronic liver failure (ACLF) remains an important issue. This study was designed to evaluate the experience in artificial liver support system (ALSS) combined with liver transplantation (LT) in the treatment of ACLF. METHODOLOGY/PRINCIPAL(More)
This report describes a 66-year-old male who had a long history of hepatitis B virus (HBV) infection. He was found hepatocellular carcinoma (HCC) 5 months after lamivudine resistance mutation and then received a successful hepatectomy. Three years later, hepatitis B envelope antigen seroconversion was achieved and nucleoside analogs were discontinued. After(More)
In China, hepatocellular carcinoma (HCC) usually develops following a long history of chronic hepatitis B infection or cirrhosis. To evaluate the diagnostic role of annexin A2 (ANXA2), a possible tumor marker, in patients with hepatitis B virus (HBV)-related HCC, particularly those with a history of cirrhosis, the present study prospectively enrolled 87(More)
