As a characteristic tumor therapy in China, Chinese medicine (CM) plays an important position in comprehensive treatment of tumor. It's a critical issue of objective realization, analysis and evaluation of CM safety for scientific decision-making in tumor safe medication and it also is a pivotal issue which affects the international communication. The safety evaluation of CM includes three phases: pre-clinical safety evaluation, clinical trials (micro-dose studies and traditional clinical trials) and post-marketing CM safety assessment. The key point of evaluation should be distinguished among different stages and various types of CM (such as classic formulas, Chinese herbal extracts, etc). Emphasis should be given to chronic toxicity when evaluating oral Chinese herbal , microdose studies and quality control must be underlined while injection is evaluated and more attention should be pay to the dose-effect relationship and time-effect relationship when turned to toxic Chinese medicine , and so as for the toxicity grading study. Moreover, we should constantly improve CM safety assessment method in various stages of tumor treatment, such as introducing the concept of syndrome classification theory, bringing in metabonomics and real-world research method which are similar to the CM therapeutic concept. Most importantly, we must keep its own feature of CM theory when we learn the concept of safety evaluation from abroad. Actively exploring the anti-tumor medicine safety evaluation methods and strategies is of great significance for clinical and experimental research, and it can provide supportability platform to CM's international communication.

METHODS:The curative effects of domestice vs. imported cefoperazone/sulbactam in 201 vs. 198 patients with lower respiratory infection in recent two years in our hospital were analyzed retrospectively. RESULTS:The effective rate was 61.6% for imported product and 51.7% for domestic product. Significant difference was noted between 2 groups statistically(P

Objective To investigate the effect of hyperbaric oxygen therapy on T-lymphocyte subpopulations in rats with acute pancreatitis. Methods 56 rats were randomly divided into three groups the sham group ( n = 8 ),control group( n = 24) and hyperbaric oxygen therapy group( treatment group, n = 24), then the control group and treatment groups were divided into three subgroups of 8 rats each undergoing euthanasia on days 1,3,7 after the acute pancreatitis induction. The CD4+ ,CD8+ subpopulations of T-lymphocytes in peripheral blood were detected respectively at the fist day and each day of the euthanasia. The sham group was used to make sure that the model was successfully induced. After euthanasia the pancrea was examined using electron microscopy. Results In the control group, the CD4+ cells in AP rats was significantly decreased and the ratio of CD4+/CD8+ also decreased. After 7days of HBO therapy,compared with the control group, the CD4+ lymphocytes of peripheral blood in the treatment group markedly increased( P ＜0.01 ). The CD8+ lymphocytes also increased to a certain extent. And the CD4+/CD8+ ratio of peripheral blood was obviously increased(P ＜0. 01 ). Also more severe pathological changes appeared in the untreated group than in the treatment group. Conclusion Hyperbaric oxygen therapy could improve the oxygen supply in acute panereatitis, regulate T cell immune function.
