ABSTRACT
Objective:To explore the role of creative mind mapping combined with problem-based learning (PBL) in the teaching of standardized residency training of oncologists.Methods:A total of 37 doctors who were trained in the Department of Oncology of Linyi People's Hospital Affiliated to Shandong University from July 2018 to June 2019 were included in the control group, receiving traditional clinical teaching; 39 doctors who were trained from July 2019 to June 2020 were included in the observation group, having creative mind mapping combined with PBL teaching. The two groups were compared with each other in terms of the examination scores (theoretical and practical operation), each dimensional scores and the total score of the Chinese version of the Critical Thinking Disposition Inventory (CTDI-CV) before and after teaching, clinical quality and teaching satisfaction. SPSS 22.0 was used for t test, chi-square test and Z test. Results:There was no statistically significant difference in the scores of theoretical knowledge and operational skills between the two groups before the regular training. After the training, the scores of theoretical knowledge and operational skills of the observation group were both higher than those of the control group [(93.42±4.21) vs. (86.58±5.32), (92.81±4.39) vs. (87.96±5.89), ( P<0.05)]. There was no significant difference between the scores of all dimensions of the CTDI-CV and the total scores of the two groups before the training ( P>0.05). After the training, the scores of the two groups were both improved, and the improvement of the observation group was more significant ( P<0.05). After the training, the scores of the doctors in the observation group on expression and communication ability, humanistic care and literacy, inductive analysis ability, clinical work adaptability, contingency handling ability, hands-on ability, and autonomous learning ability were significantly higher than those of doctors in the control group ( P<0.05). After the training, the total satisfaction of the doctors in the observation group was higher than that in the control group [97.44% (38/39) vs. 81.08% (30/37)], and the difference was statistically significant ( P<0.05). Conclusion:The application of creative mind mapping combined with PBL in the teaching of standardized residency training of oncologists can significantly improve the learning effect of the training doctors, improve their critical thinking ability and clinical comprehensive ability, and can also improve their total satisfaction with teaching.
ABSTRACT
OBJECTIVE To investigate the optimal surgical approach and compatible material for large nasal septal perforation.METHODS Operations were underwent via labiogingival groove approach under endoscope.Double layer of flaps were perichondrium of nasal septal cartilage,base of nasal cavity and inferior nasal meatus on the left and acellular dermal matrix (ADM) on the right and the two flaps were adhered with ear-cerebral glue (EC).RESULTS All of 36 cases were successfully repaired and no reperforation occurred after following-up for 3 months to 2 years.CONCLUSION Large mucosal flaps with wide pedicel and abundant blood supply and ADM of good biocompatibility provide a higher survival rate of the flaps.This method has the advantages of wide field of vision,less damage of the donated area and short time of operation.It is an optimal and practical method for repair of the large nasal septal perforation.
ABSTRACT
Objective To study a fingerprint of raw material of Rhizoma Polygoni Cuspidati from(various) habitats by RP-HPLC. Methods Kromasil C_(18) column(150 mm?4.6 mm,5 ?m) was used,with mixtures of acetonitrile and water as mobile phase in a gradient mode.The flow rate was 1 mL/min and wavelength was 303 nm.Results According to the optimum chromatographic conditions,a good fingerprint of Rhizoma Polygoni Cuspidati has been described.Conclusion The method is simple and accurate with good reproducibility.It may be practical value for the quality control of sample for Rhizoma Polygoni Cuspidati from various habitats.
