ABSTRACT
AIM: To evaluate the efficacy of 0.01% hypochlorous acid as a conjunctival sac disinfectant before cataract phacoemulsification and its impact on the ocular surface.METHODS: Randomized controlled clinical trial. A total of 285 patients who were scheduled for cataract phacoemulsification surgery were randomly divided into the hypochlorous acid group and the povidone iodine group. Before and after disinfection, conjunctival sac swabs were taken, and bacterial culture and colony-forming units(CFUs)testing were performed using blood agar and chocolate agar media, respectively. All patients were evaluated for ocular symptom scores and pain severity scores 2 h, 1 d, and 1 wk after disinfection, and underwent corneal fluorescein staining, eye redness index, tear meniscus height, and noninvasive breakup time(NIBUT)examination. The incidence of endophthalmitis after surgery was recorded.RESULTS: Conjunctival sac disinfection with 0.01% hypochlorous acid significantly reduced the rate of positive bacterial cultures and colony-forming ability of the conjunctival sac, with statistically significant differences compared with the pre-disinfection period(both P<0.01), and the disinfecting ability of hypochlorous acid was comparable to that of povidone-iodine(χ2=0.811, P=0.368). The scores of ocular symptoms and pain severity in the hypochlorous acid group were significantly lower than those in the povidone-iodine group(both P<0.01). The corneal fluorescein staining and eye redness index in the hypochlorous acid group were significantly lower than those in the povidone-iodine group(all P<0.01). No endophthalmitis occurred in either group of patients. CONCLUSION: As a conjunctival sac disinfectant, 0.01% hypochlorous acid is safe and effective, with minimal discomfort and damage to the ocular surface in patients.
ABSTRACT
Due to the cultural lack in second documents'analysis of medical tangle,and the clinical teachers'three bases weakening,the facts that medical students fail to devote to communication between hospitals and patients,and the disjunction between the practice outline and clinical practice,trigger the reflection on the teaching professional level and the educational quality.First,we carry out the systematic construction of chnical practice teaching which includes aim orientation,curriculum design,resource integration,quality management and effectiveness evaluation.Second,we inelusively develop clinical professional skiUs and humanist accomplishment.Above all,we take the initiative to conform the teaching,including knowledge,technology,methods,and implement,to the incubation containing virtue,group,labor and pleasing,all of which promote a variety of needs of study and teaching
ABSTRACT
Faced with the rate’s drop of the Chinese clinical graduates’physician qualification examination and the experimental evaluation feedbacks from global medical education standard, we set up a research in clinical teaching bases’educational guarantee mechanism of medical colleges and universities. With the action research method and the descriptive studies in the definition of guarantee mechanism, the demand of graduates, the system of clinical lectures and the revolution of teaching mode, the standard of education, the system of basic condition datadetection, and the planning and the policy of clinical teachers’growth, we constructed the technical route of the leader’s supporting responsibilities, the teachers’professional roles and the students’ clinical teaching bases’ quality. We applied an empirical study in affiliated and non-affiliated hospitals of western and Chinesetraditional medicine and achieved predicted effort.
ABSTRACT
International services trade in the light of the principles of WTO makes a dif-ference in medical domain when confronting the direction of the global educational services. The Ministry of Education Project,"The Research of medical distance education and practice pattern in rural areas in west China",establishes an educational platform of modern service in central China, invests nursing human resources of west China and outputs vocational standard patients in east China,which provides school of medicine,especially English class of Chinese system,with abundant social teaching resources and has been adopted as Shanghai Human Resources Training Project.
ABSTRACT
It is necessary to integrate students, teachers and content with learning-centralization so that time and space will no longer be parted in modern distance-education system. Guided by KAQ pattern, we suggest that we should integrate subjects in teaching activity, form support system and normalize information management process. All these are essential for the project of modern distance education.
