Drug clinical trial is an important link in the chain of new drug research and development. The results of drug discovery and development directly depend on the extent of standardization of clinical trials. Therefore, improving the quality of drug clinical trials is of great importance, and drug clinical trial institutions play a crucial role in the quality management of drug clinical trials. After years of development, the overall level of drug clinical trials has advanced rapidly in China, and a large number of clinical trials of traditional Chinese medicine have also been carried out. However, there is still a big gap between our country and developed countries. Therefore, for the construction and management of Chinese drug clinical trial institutions, there is still a long way to go. This study aims to analyze the current development of drug clinical trial institutions in China and explore the existing problems from three aspects, including current situations of institutional organization and management, regional and professional distributions, and quality control. And some suggestions are put forward finally, including support of traditional Chinese medicine, introduction of drug-risk management system, and construction of information management.

Conclusion The method is simple, reliable and rapid, and can be applied to the quality control of Yishenling granules (Sucrose-free).

About 50％ to 60％ of the stage Ⅱ-Ⅲ colorectal carcinoma patient suffer from liver metastases.Recently,there is a research hotspot on how to improve the prognosis of the colorectal carcinoma liver metastases (CRLM) patient.It can elucidate the way how the carcinoma cells transfer from the original tumor to the liver,through establishing a CRLM animal model.An ideal CRLM animal model should perfectly mimic the total procedure of the metastases pathway,including the change of the cytology behavior and the development of the tumor biology.Besides,the model should be practical,tumor-predictable and accord with the ethical consideration.Until now,there is not an ideal CRLM animal model can perfectly match those conditions.This review goes through the advantages and disadvantages of different CRLM animal model methods used for research.

Objective To observe the inhibition of vascular endotheilal growth factor (VEGF) gene transcribition and translation with antisense VEGF165 adenovirus vector transfection. Method To transfect the synovial cells with antisense VEGF165 adenovirus and detect the gene translation level with northern-blot method. Result The Northern-blot showed that: the transcription of VEGF gene were inhibited markedly after the antisense VEGF165 gene transfection for 3 days and the inhibition efficiency was obivious in 4th day. In the 5th day, the VEGF translation signal was hardly detected. Conclusion The antisense VEGF165 adenovirus gene transfection can inhibite not only the transcription but the translation of VEGF gene in synovial cells. Thus it can inhibit the secretion of VEGF in synovial cells with high efficiency.
