ABSTRACT
Objective To investigate the effects of video-assisted thoracoscopic surgery (VATS) teaching in clinical education of the five-year undergraduates.Methods 50 undergraduate clinical interns were divided randomly into the experimental group and control group.The experimental group was applied with traditional method combined with VATS,and the interns studied the radical operation of lung cancer under thoracoscopy,while the control group was applied with traditional method.After the course,all students accepted theory and clinical examination,and a questionnaire survey was conducted.SPSS 18.0 was used for statistical analysis,and t-test was adopted for theoretical and clinical examination results.Questionnaire survey was conducted by chi-square test.Results ①Theory test:compared with control group,the scores of case analysis [(38.92 ± 2.50) vs.(34.56 ± 3.10)] and total scores [(79.92 ± 4.04) vs.(74.64 ± 4.82)] were improved (P＜0.05).②Clinical test:compared with control group,the scores of experimental group [(82.86 ± 4.46) vs.(76.04± 4.78)] were improved (P＜0.05).③Questionnairesurvey:there was statistical difference between the two groups in promoting the interest in learning,improving the comprehension of knowledge and approving of the teaching method used (P＜0.05).Conclusion VATS teaching method has positive effect on clinical education of the five-year undergraduates,and it should be worthy of extending.
ABSTRACT
Objective To investigate the distribution and antibiotic resistance of the enteric pathogens in Shanxi province to guide the choice of antibacterials.Methods 798 cases of fecal samples from patients with diarrhea were treated in the outpatient and inpatient.The suspected pathogen was separated then PCR,biochemical test,serum agglutination tests were used for identification of suspected pathogen,and bacterial pathogens constitution and patho-genic characteristics were analyzed.Antimicrobial susceptibility testing was conducted by diskdiffusion method for the suspected pathogen with 6 antimicrobial agents.Results 81 strains isolated from 798 specimens were positive with 10.15% for pathogen detection.Diarrheagenic Escherichia coli was the first frequently pathogen,accounting for 46.91%,followed by Shigella,Salmonella and Aeromonas.Drug sensitivity monitoring showed that the most of the 81 strains had lower level of resistance to cefoitin,cefotaxime and ciorofloxacin,and higher level of resistance to tetra-cycline and nalidixic aid.Conclusion Diarrheagenic Escherichia coli,Shigella,Salmonella and Aeromonas are the major bacterial diarrheal pathogens in the hospital.Surveillance of antimicrobial resistance in these bacteria should be strengthened to provide reliable evidence for clinical anti infection treatment.
