ABSTRACT
Objective:To explore the effectiveness of clinical pathway (CP) and team-based learning (TBL) teaching method in standardized residency training of gynecology.Methods:The research included 40 residents as objects who took standardized training in gynecological rotation in Luohe Central Hospital from July 2017 to July 2019, and they were randomized into experimental group and control group. The combination of CP and TBL teaching method was used in the experimental group ( n=20), while the traditional teaching method was applied in the control group ( n=20). All residents were tested for the professional theory and clinical skill after training. After the training, a survey about the teaching satisfaction and the effectiveness of teaching methods was conducted for both groups. Statistical analysis was performed by SPSS 23.0 software. Results:The average scores of professional theory and clinical practice skills in the experimental group were (85.55±5.96) points and (89.90±6.40) points respectively, which were better than the average scores of the control group [(76.36±6.68) points and (75.50±4.81) points, respectively], and there were significant differences between two groups ( P<0.05). The results of the questionnaire survey showed that the experimental group residents had a higher degree of satisfaction and a higher evaluation of the teaching method than the control group. Conclusion:CP and TBL teaching is beneficial to improve the quality of standardized residency training of gynecology, and it is suggested to make wide popularization and application in the training.
ABSTRACT
[ ABSTRACT] AIM:To investigate the mechanism underlying breast cancer metastasis and to provide theoretical da-ta for studying the pathogenesis of breast cancer onset and development.METHODS: Human breast cancer MCF-7 cells were treated with different concentrations of furin inhibitorα1-PDX for 48 h.Wound healing assay and Transwell assay were applied to detect the migration and invasion abilities of the MCF-7 cells.The expression of cell migration-associated proteins, including membrane-type 1 matrix metalloproteinase ( MT1-MMP) , vascular endothelial growth factor ( VEGF)-C and VEGF-D, was determined by Western blotting.The protein levels of MMP2 and MMP9 in the supernatant were measured by ELISA. RESULTS:Compared with control group, 200 nmol/L of furin inhibitor exerted significant inhibitory effects on the cell mi-gration (P<0.05).The expression of cell migration-associated proteins MT1-MMP, VEGF-C and VEGF-D was significantly inhibited after treated withα1-PDX ( P<0.05 ) .Significant inhibitory effects of α1-PDX on the expression of MMP9 and MMP2 (P<0.05) in the supernatant were observed.CONCLUSION:Furin inhibitor suppresses the metastasis of MCF-7 cells via down-regulating the expression of MMPs and VEGFs.
ABSTRACT
AIM: The contents of pachymic acid in Poria in different parts and in different localities were measured and compared. METHODS: 9 samples were measured with HPLC. RESULTS: The content of pachymic acid in Fushen is the highest in different parts and the content of pachymic acid in Guangxi province is the highest in five localities. CONCLUSION: The content of pachymic acid was obviously variable in different parts and this result made the basis of the application of with the different parts of Poria. The content of pachymic acid wasn't obviously variable in different localities.
