ABSTRACT
Objective:To investigate the effect of situational simulation combined with video feedback in cardiopulmonary and abdominal clinical probation of diagnostics.Methods:Two hundred and twenty-four clinical undergraduates from the second affiliated hospital of Guangxi Medical University were randomized into the experimental group ( n=112) and the control group ( n=112). The experimental group applied situational simulation combined with video feedback methods in the cardiopulmonary and abdominal clinical probation. In other words, according to the assignment of diseases, two students played the role of "physician and patient" and conducted corresponding consultation and physical examination, in which the positive and negative video feedback were integrated to standardize students' physical examination skills. The control group adopted conventional teaching method. The teaching effect of the two groups was evaluated through unified and standardized scores of theoretical tests, cases analysis, and clinical skills operation, and the experimental group was conducted anonymous questionnaires to 112 students. SPSS 22.0 was used to perform the t test. Results:The evaluation results show that the average scores of theoretical tests (90.12±0.94), cases analysis (9.30±0.10) and physical examination (93.50±0.72) in the experimental group are higher than those of the control group, (83.20±1.66), (8.10±0.11), (85.00±1.75), respectively, with statistical significance ( P<0.05). All 112 questionnaires were collected, with an effective rate of 100%. The percentage of "yes" respondents is as follows, 91.1% of "Enhancing the mastery and application of knowledge"; 97.3% of "Cultivating clinical thinking"; 87.5% of "Improving doctor-patient communication skills"; however, there are 93.8% students believe that this new teaching approach takes more time to prepare before class, consequently, their initiative and enthusiasm of study and learning interest have slid into decline, with percentage of 80.4% and 83.0%, respectively. Conclusion:The teaching method of situational simulation and video feedback in cardiopulmonary and abdominal clinical probation of diagnostics is beneficial to enhance students' understanding and mastery of theoretical knowledge, standardize physical examinations, cultivate clinical thinking ability and improve the doctor-patient communication skills. However, it takes a lot of time for students to prepare before class. If they fail to make reasonable arrangements, the teaching effect will be half the effort and students' initiative and enthusiasm of learning will be reduced.
ABSTRACT
Objective To compare the efficiency of National Early Warning Score (NEWS),Chronic Respiratory Early Warning Score(CREWS) and BAP-65(elevated Blood urea nitrogen,Altered mental status,Pulse＞109bpm,age＞65 years)among patients with AECOPD (acute exacerbations of chronic obstructive pulmonary disease).Methods Totally 181 patients with AECOPD were investigated by these three scales,and the efficiency of NEWS,CREWS and BAP-65 was compared.Results The scores of NEWS,CREWS and BAP-65 in the death group were higher than those in the survival group and the general ward group(P＜0.01).Regarding the predicted results of hospital death,the area under the ROC curve of NEWS,CREWS and BAP-65 was 0.878,0.836 and 0.774,respectively,and the differences were not statistically significant(P＞0.05);for predicted results of ICU admission,the area under the ROC curve of NEWS,CREWS and BAP-65 was 0.826,0.813 and 0.716,respectively,and the differences were not statistically significant (P＞0.05).Conclusion NEWS,CREWS and BAP-65 have satisfied predictive efficiency for prognosis,and NEWS and CREWS are much easier and faster to use.
ABSTRACT
@#AIM: To observe the effect of amniotic membrane transplantation(AMT)in exposure keratitis.<p>METHODS: A prospective study of 14 cases(19 eyes)with exposure keratitis were treated with AMT in our hospital from September 2015 to September 2016. The patients were resistant to various conventional medications. The time of amniotic membrane absorbed, corneal opacification, fluorescein staining, visual acuity, complications and recrudescence were observed after transplantation. <p>RESULTS: Amniotic membrane started to dissolve in 3-5d and fell off within 7-14d after transplantation in all patients. Slit-lamp examinations showed that the cornea turned transparent in 16 eyes. There were significant diffrrences in the scores of corneal opacification and fluorescein staining at 28d after treatment compared before treated(<i>P</i><0.05). Visual acuity increased in all patients to varying degree with no complications. <p>CONCLUSION: AMT has a good effect in the treatment of exposure keratitis.
ABSTRACT
The advantages of intense pulsed light therapy in the treatment of Meibomian gland dysfunction include non-invasive, painless and good results, which has been greatly developed in the ophthalmology field.This article reviews the current situation, mechanism of action, operating procedures, treatment outcomes, safety, and other aspects of intense pulsed light therapy in the treatment of Meibomian gland dysfunction.
ABSTRACT
AIM:To investigate the effect of intense pulsed light on the meibomian gland dysfunction ( MGD) , and to observe whether the intense pulsed light can improve the symptoms and objective indexes of the patients with meibomian gland dysfunction. · METHODS: A retrospective noncomparative interventional case series was conducted. Totally 21 MGD patients (42 eyes) were selected from November 2016 to February 2017 in Renmin Hospital of Wuhan University, the results of the following tests is recorded:OSDI score, corneal fluorescein staining, tear break-up time, ocular surface analyzer, scanning confocal microscopy, all patients respectively were received intense pulsed light treatment 3 times at 3wk intervals, and followed up after 1mo. Paired sample t test was used to analyze the difference in outcome. ·RESULTS: In the 21 cases ( 42 eyes ) , the OSDI score decreased, the mean value before treatment was 30. 18 ± 4. 07, and the mean value after treatment was 24. 87±4. 32. The first tear film break-up time ( first, BUT) increased, the mean value before treatment was 5. 37 ± 0. 82s, the mean value after treatment was 7. 12 ± 0. 74s. The mean value of meibomian gland secretion scores before the treatment was 1. 57 ± 0. 52,the mean value after treatment was 1. 22 ± 0. 52. The mean value of corneal fluorescence staining before treatment was 0. 82 ± 0. 41, and the mean value after treatment was 0. 51 ± 0. 53, the difference was statistically significant (t=11. 2, 2. 68, 3. 31, 2. 78, 2. 61;P<0. 05). · CONCLUSION: Intense pulsed light can effectively improve the subjective symptoms of patients with MGD and alleviate the obstruction of meibomian glands. It is an important method for MGD treatment.
