ABSTRACT

Objective To investigate the innovation ability status of undergraduate students in Third Military Medical University,and put forward some effective suggestions.Methods A questionnaire was applied to survey the innovation ability status of undergraduate students in Third Military Medical University.A total of 210 valid questionnaires were collected.The questionnaires covered five aspects including undergraduate students' basic information,innovative consciousness,innovation thinking,innovation skills and basic knowledge.The results were assessed by using SPSS 19.0 statistical software for t-test or ANOVA of students from different grades,majors and academic years.Inspection level was α=0.05.Results The total score of innovation ability in undergraduates was (70.5 ± 8.2) point,and no significant difference was observed in the total score of undergraduates' innovation ability within different grades (P=0.435).However,the innovation thinking ability of undergraduates in Grade Four was significantly higher than that in Grade Two [(77.0 ± 10.7) vs.(72.6 ± 10.9),P=0.030)],and the score of basic knowledge of undergraduates in Grade One was significantly higher than that in Grade Four [(76.2 ± 6.0) vs.(69.3 ± 8.7),P=0.014)].The total score of innovation ability of undergraduates from clinical medicine was significantly higher that of undergraduates from preventive medicine and other majors [(72.5 ± 8.8) vs.(69.9 ± 7.5),P=0.035;(72.5 ± 8.8) vs.(66.7 ± 7.9),P=0.004].There were no significant differences in total score of innovation ability or score of any first level index of undergraduates between eight-and five-year system of preventive medicine (P>0.05).Conclusion The overall innovation ability of undergraduates in military medical university was relatively high,and undergraduates from different grades,majors and academic years have their own special advantages in innovative consciousness,innovation thinking,innovation skills and basic knowledge,and it is necessary to carry out more researches focusing on educational and training mechanism of innovation ability according to the personality of undergraduates in military medical universities.

ABSTRACT

Objective The role of this essay is to explore the relationship of BIM deletion polymorphism and paclitaxel intrinsic resistance in breast cancer. Methods Human breast cancer cell lines were screened by techniques of PCR and gene sequencing to detect BIM deletion polymorphism.MTS was used to detect the cytotoxic effects of paclitaxel in different cell lines. Meanwhile,levels of BIM mRNA and protein were detected by rtPCR and Western Blot. Results Comparing with the wild type cell line(MCF7),T47D was a deletion cell line with BIM deletion polymorphism and resistant to paclitaxel(T47D vs.MCF-7,IC50>30le vs.IC50=0.16 vs.02 μmol/L). Moreover,the ratio of BIM EXON3 to EXON4 was significantly increased and the level of functional BIM protein was down-regulated in T47D compared with MCF7(P < 0.05). Conclusion BIM deletion polymorphism might initiate intrinsic resistance to paclitaxel therapy in breast cancer.
