Epidemiology of hepatitis B and associated liver diseases in china.

Hepatitis B virus (HBV) infection has long been a critical public health challenge in China. National surveys revealed a prevalence of approximate 10% for chronic HBV infection in general population. HBV has been the leading cause of chronic hepatitis, cirrhosis, and liver cancers in Chinese population and a common pathogen of acute viral hepatitis. Meanwhile, the epidemic provided important opportunities to research the natural history, public health impact, and therapeutic and preventive interventions for HBV in China. In this review, we summarized the selected key epidemiological studies since 1970s regarding HBV infection and its associated liver diseases in China, and provided considerations for future research, prevention and treatment of HBV.

Expansion of China's free antiretroviral treatment program / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>In 2003, China's National Free Antiretroviral Treatment Program (NFATP) was initiated as a pilot, which covered only 100 HIV/AIDS patients. By 2011, the pilot had evolved into a nationwide program and had provided free treatment for over 150 000 patients. The objective of this study was to report and evaluate the progress of China's free antiretroviral treatment program.</p><p><b>METHODS</b>The NFATP Database was systematically reviewed and a total of 150 692 HIV/AIDS patients were included in this study. Program progress indicators including the number of treated HIV/AIDS patients, follow-up visit rate, CD4 test rate, and viral load test rate were summarized and examined over a calendar year to evaluate the progress of NFATP quantitatively and qualitatively.</p><p><b>RESULTS</b>By the end of 2011, a total of 150 692 HIV/AIDS patients had been treated through the NFATP and 122 613 of them were still on treatment. Of all patients, about 72% were enrolled during the past four years. The dominant transmission route was blood related in the early phase of the NFATP, but gradually changed to sexual contact. Besides quantitative improvements, progress indicators also demonstrated significant qualitative improvements that the program had made during the past 9 years.</p><p><b>CONCLUSIONS</b>Great achievement has been made by China's NFATP. China's experience indicates the importance of a comprehensive response to the success of its treatment program. However, to ensure the quality and sustainability of treatment in the long term, more attention and resources should be paid towards program management.</p>
