Methods： Two classes from the 2012 senior graduating nursing class were randomly selected by a computer to conduct the diversified practical teaching methods based on animal experimentation. A hospital environment was simulated by requiring students to perform different types of injections and practical IV infusion techniques. A comprehensive evaluation of the core professional competencies, as well as other integrated competencies, was conducted to determine the effectiveness of the teaching methods. Results： Two-sampled, pairwise u-tests were performed between the scores of the experimental （nursing class 2） and control （nursing class 1） groups. These findings showed that the overall test scores were significantly higher in the experimental group compared to the control group and that the average P-values for the competencies in various categories were 〈0.01, which indicated statistically significant results. Conclusions： Based on the data from this project, diversified teaching methods for basic nursing training founded on animal experimentation can help nursing students perfect their core professional competencies and improve their overall professional standing. The introduction of animal experimentation requires further verification, and an increased acknowledgement of its benefits through the widespread dissemination of this information.展开更多

There are differences between TCM and chemical drugs. For TCM, the multiple components in vivo are possibly to be detected; the number of components is relatively restricted; they could represent the therapeutic effect of the parent recipe; the concentrations and pharmacokinetics （PK） could affected by the combination of traditional medicines in recipe; the effects of new bioactive compounds （metabolites） related with those of their recipe; and the PK can be affected by body state in TCM treatment significantly. Therefore, the difficulty and challenge are far greater in PK study of TCMs than the chemical drugs.展开更多
