ABSTRACT
Objective:To evaluate the effectiveness of medical practical training with a multi-level comprehensive model.Methods:We randomly selected 100 medical undergraduates who received practical training in The Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from 2017 to 2019, 20 medical education experts, and 30 teachers for a questionnaire survey using self-designed questionnaire with 3 first-level items, 8 second-level items, and 31 third-level items. Data processing and analysis was made by multi-level comprehensive model.Results:The comprehensive evaluation data (0.176 4, 0.512 3, 0.252 5, 0.058 8) obtained by the multi-level comprehensive model showed that the proportions of medical undergraduates achieving excellent, good, moderate, and poor effects of medical practical training were 17.64%, 51.23%, 25.25%, and 5.88% respectively. According to the principle of maximum membership, the final comprehensive evaluation result of the effectiveness of medical practical training was "good".Conclusion:This research has demonstrated the scientificity and feasibility of using the proposed multi-level comprehensive model to evaluate the effectiveness of medical practical teaching. In the comprehensive evaluation, the quantitative processing of qualitative indices can generate the matching score of each index in the multi-level index system. The evaluation results are intuitive and easy to analyze, thus providing the basis for the targeted improvement of medical practical teaching effect.
ABSTRACT
Objective To explore the application of fuzzy mathematics theory in the evaluation of medical students' comprehensive mental quality. Methods A total of 80 medical undergraduates studying in the Affiliated Huai'an No.1 People’s Hospital of Nanjing Medical University from October to December 2017 were randomly selected to conduct a questionnaire survey on medical students' mental quality. The questionnaires were designed by the study group, containing 3 first-level items (learning pressure, life stress and interpersonal stress), and 19 secondary items, with the recovery rate as 95%. Fuzzy comprehensive evaluation method was used for data processing and analysis. Results By comparing the data obtained from the comprehensive evaluation of the secondary factors with those of the pre-set evaluation set, the study concluded that 25.00% of the medical students need to adjust the future pressure, 41.70% the family health status pressure and 26.79% the appearance pressure according to the principle of maximum mem-bership degree. The comprehensive evaluation of the first four factors (0.249 7, 0.268 9, 0.270 2, and 0.211 2) showed that the comprehensive mental quality of medical students was "good". The quantitative analysis results showed that 27.02% of the medical students had good comprehensive mental quality, 24.97% need the mental quality adjustments, 26.89% had the average mental quality, and 21.12% had outstanding mental quality. Fuzzy comprehensive evaluation indicated that it is necessary to adjust the learning pressure and life stress of medical students, while the interpersonal stress had little effect on the mental quality of medical students. Conclusion The fuzzy comprehensive evaluation adopts the quantitative method to deal with the qualitative indicators uniformly, being scientific and reasonable. The corresponding data of each indicator can be easily identified with the help of the indicator system built up in the evaluation, which provides evidence for distinguishing and improving the corresponding decision-making for improving the medical students' mental quality. This evaluation method has strong applicability and provides new methods and ideas for objectively evaluating the comprehensive mental quality of medical students.
ABSTRACT
Objective @#To investigate the effectiveness of fluoride varnish in preventing first permanent molars caries inschool-age children and provide necessary information for oral health instruction. @*Methods@#378 children aged 6-7 years old in the first grade of primary school in dahua country, hechi city, Guangxi province (1 053 first permanent molars) were randomly recruited into 2 groups. The test group (542 first permanent molars in 191 children) was treated with fluoride varnish one time in a half year and given oral hygiene instruction 3 times; The control group (511 first permanent molars in 187 children) was only given oral hygiene instruction 3 times. All first permanent molars were checked after 18 months later for caries. @*Results@#After intervention, the caries prevalence rate in the test group raised from 21.99% to 27.75% compared with the control group from 24.60% to 37.43%. The caries incidence rate in test and control group was 5.76% and 12.83% respectively. There was a significant difference between 2 groups regardless of caries prevalence, caries incidence, the DMFT reduction, the DMFs reduction, the occlusal caries prevalence, the pit and fissure caries prevalence, the proximal caries prevalence. @*Conclusion @#Semi-annual application of fluoride varnish is effective in the prevention of dental caries in first permanent molars , which was worth of being popularized in clinic.
ABSTRACT
Objective To make contrast analysis of sleeve lobectomy and wedge resection in lung cancer treatment by observing the clinical curative effect.Methods 100 patients with lung cancer using random table method, all the patients were divided into the observation group ( 50 cases, treated with sleeve resection ) , control group (50 cases,treated with wedge resection),follow-up after treatment lasted respectively for 3 years.Results In the two groups,anastomotic fistula incidence and mortality rates of the observation group were 4%,6%;6% and 8% in the control group,there were no statistical difference (χ2 =0.00,0.00,all P>0.05);the positive rate of stump cancer cell bronchial in the observation group was 4%,it was obviously less than 16% in the control group,and the differ-ence was obvious (χ2 =4.00,P<0.05) .The anastomotic scar tissue hyperplasia and recurrence rate of the observa-tion group during the follow-up period were 2%,2%;which were lower than 16%,18% of the control group (χ2 =4.40,7.11,all P<0.05).The 1,3 year survival rates of the observation group were 92%,64%,which were higher than 62%and 42%of the control group (χ2 =12.70,4.86,all P<0.05).Conclusion Taking sleeve resection for bronchogenic carcinoma can effectively control the positive rate of bronchial stump with cancer cells,inhibit anasto-motic scar tissue hyperplasia,reduce the recurrence rate,and the curative effect is very good,which is worth of clinical application.
