China has initiated cooperation with USDOE on natural gas utilization, distributive power sources, and green Olympic resources planning. China also staged 12 collaborating projects with Australia on food safety, medical care, and meteorology.
New Progresses for Liver Cancer Pathogenesis
A research team, led by Prof. WANG Fusheng with No. 302 PLA Hospital Institute of Infectious Diseases, has found for the first time in the world that the increased number of regulating T cells in liver cancer patients may result in the injury of CD8T lymphocytes and a shortened survival time. The finding was published in a recent issue of journal Gastroenterology.
Researchers in the team have worked closely with clinical cases, conducting an in-depth study of 123 patients having both chronic hepatitis B and liver cancer. A comparison between 21 hepatocirrhosis patients and 47 healthy subjects showed that regulating T cells had an abnormal increase in liver cancer patients by 2 to 10 times that of healthy subjects, and 1.5 times that of hepatocirrhosis patients. The increase of regulating T cells would further go up, along with the advancement of liver cancer. Statistical analysis also showed that the increased number of regulating T cells can noticeably affect the survival time of liver cancer patients. Further clinical experiments confirmed the fact that the abnormally increased regulating T cells have a direct contact with CD8T lymphocytes, which deprived CD8T of its tumor fighting function by injuring, allowing malignant multiplications of liver cancer cells.
The finding has not only elaborated the key role played by T cells in immune pathogenesis, but also found that regulating T cells can be used as a clinical indicator for evaluating the advancement of the disease. It creates a new approach for immune therapy of liver cancer.
Langchao Server Breaks World Record
Not long ago, SPEC published the test results of Chinese made four-core server. Developed by Langchao Group, the double-circuit four-core server is able to process 1538 acts per second, which updated the top record registered by HP server in the past eight months.
