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.

Objective To improve the key steps of direct volume rendering(DVR) method to obtain ideal semitransparent 3D visualization of medical images from 2D slices.Method An arbitrary data set was classified into a simple one and a complex one according to the boundaries existing within the data set,thereby a piecewise linear function was used to construct the transfer function(TF).Low-grayed voxels were regarded as a kind of material which did not radiate but do induce attenuation of sampling lights.The TF was adjusted according to the opacity distribution when one resampling process ends,and the rendering procedure was completed.Result Interior structures of tissues in different levels were rendered.Conclusion Multi-level visualization of 3D medical images for the semitransparent effect can be obtained by considering all the tissues in the data set as semitransparent materials.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.
