Objective This article was aimed to take exploratory evaluation on the scientific research performance of provincial key disciplines in a medical university,and to provide a scientific basis for the discipline evaluation related topics.Methods This paper took 29 provincial key disciplines in a medical university as the evaluation system.We calculated the scientific research performance of key disciplines.Data envelopment analysis (DEA) method was used to evaluate the scientific level of performance,while the use of TOPSIS and gray correlation analysis method to rank the efficiency of its research,and the results obtained by the three methods was used for statistical correlation analysis.Results According to the results calculated by DEA Method,there were 18 DEA efficient units and 11 non-DEA efficient units.While in this 11 non-DEA efficient units,8 of them needed to reduce re source inputs and the other 3 units needed to increase research outputs.Meanwhile there were significant positive correlations between evaluation results of TOPSIS Method andGrey Correlation Analysis Method with Data Envelopment Analysis Method,respectively [the correlation coefficient:rs 1 =0.797(P =0.000); rs 2=0.583(P =0.007); rs 3-0.536(P =0.003)].Conclusions Compared to TOPSIS Method and Grey Correlation Analysis Method,DEA Method not only could evaluate the ef fectiveness of discipline,but also provide evidence to improve the non-DEA efficient units.

BACKGROUND:Animal modeling has reported that psychological stress can lead temporomandibular joint disease in rats, and there wil be pathological changes.
OBJECTIVE:To observe the effects of psychological stress on the expressions of vascular endothelial growth factor and transforming growth factor-β1 in rat temporomandibular joint condylar chondrocytes
METHODS:Forty-eight adult male Wistar rats were randomly divided into the experimental group and the control group, 6 rats in the experimental group and 12 rats in the control group. Thirty-six Wister male adult rats in the experimental group were subjected to the fol owing stimulating factors, such as electroshock, keeping stil ness, climate change and food tempting in order to make them under psychological stress. Then, the experimental group rats were executed at 3 weeks after stimulation (3 weeks stimulation group), 6 weeks after stimulation (6 weeks stimulation group) and 6 weeks normal feeding after 6 week stimulation (recovery group), 12 rats were sacrificed at each time point. The 12 rats in the control group were executed at the same time as the last experimental group. The temporomandibular joint specimens were taken to produce slices.
RESULTS AND CONCLUSION:The vascular endothelial growth factor-positive rate of recovery group was significantly larger than that of the 3 weeks stimulation group and the control group (P<0.05);transforming growth factor-β1 positive rate in the 6 weeks stimulation group was significantly greater than that in the control group (P<0.05). It indicated that vascular endothelial growth factor was related with the new blood capil aries repairing tissue, and transforming growth factor-β1 might play a role that stimulates bone resorption in psychological stress.
