RESUMO
Objective:To investigate the value of chain management of perioperative pressure injury in patients undergoing supine craniocerebral injury, so as to provide reference for the prevention of pressure injury and the application of chain management.Methods:In this retrospective study, a total of 116 patients with craniocerebral injury who underwent supine surgery in Shanxi Cardiovascular Hospital from December 2019 to December 2020 were included in the control group, using traditional perioperative pressure injury management protocol. And 124 patients admitted from January 2021 to December 2021 were included in the observation group, and were managed by the pressure injury chain management scheme. The risk assessment/judgment rate of pressure ulcers, the risk assessment/judgment accuracy rate of pressure ulcers, the implementation rate of intervention measures, the qualified rate of intervention records and the reported rate of high-risk patients with pressure ulcers in the two groups were analyzed. The occurrence of stress injury and medical expenses of the two groups of patients were investigated.Results:The risk assessment/judgment rate of pressure ulcers, the risk assessment/judgment accuracy rate of pressure ulcers, the implementation rate of intervention measures, the qualified rate of intervention records and the reported rate of high-risk patients with pressure ulcers were 100.00%(124/124), 96.77%(120/124), 92.74%(115/124), 93.55%(116/124), 100.00%(29/29) in the observation group, which were 77.59%(90/116), 72.41%(84/116), 68.97%(80/116), 68.97%(80/116), 83.33%(30/36) in the control group, the difference was statistically significant ( χ2 values were 22.24-31.17, all P<0.05). The overall incidence of stress injury in the observation group and the control group was 15.52%(18/116) and 3.23%(4/124), respectively, and the difference between the two groups was statistically significant ( χ2=10.88, P<0.05). There was no significant difference in the total hospitalization cost between the two groups ( P>0.05). The cost of stress-related consumables was (144.94 ± 47.28) yuan in the observation group and (194.21 ± 55.76) yuan in the control group, and the difference was statistically significant ( t=7.40, P<0.05). Conclusions:Perioperative stress injury chain management can reduce the incidence of pressure injury in patients with craniocerebral injury, improve service quality, and reduce medical costs, with good clinical application value.
RESUMO
Objective:To explore the implementation method of case teaching in pharmacology teaching according to the standards of golden course.Methods:The students from Batch 2017 clinical medical students in our university were selected as the research objects, and randomized into the control group ( n=121) and the case teaching group ( n=171). The control group used online learning and traditional lecture, and the case teaching group adopted the online teaching and case teaching methods. And the teaching effect was evaluated by questionnaire survey and final performance analysis. Results:Compared with control group, the case teaching group had better final performance ( P<0.01). The questionnaire survey showed that the case teaching improved the learning interest of students and also enhanced their application ability of the knowledge ( P<0.01 or P<0.05). Conclusion:Case teaching has achieved good teaching effect in pharmacology teaching.
RESUMO
Aim To investigate the antitumor and antiangiogenic effects of combined low-dose cyclophosphamide(CTX)and recombined VEGF protein vaccine.Methods In this experiment,H22 hepatocellular carcinoma model was established in BALB/c mice.Mice were randomly divided into four groups: control group,CTX group(CTX),VEGF protein vaccine group(V2)and CTX plus V2 group(CTX+V2).The anti-tumor efficacy and antiangiogenic effect were investigated using a subcutaneous tumor model and an intradermal tumor model.Western blot and ELISAwere further adopted to detect the specific anti-VEGF antibody.Results CTX+V2 group displayed a lower tumor volume and tumor weight than either the single therapy group in the subcutaneous tumor model(P<005 vs V2,P<001 vs CTX).Meanwhile,CTX+V2 was more effective for antagonizing tumor-associated angiogenesis compared with either the single therapy(P<005 vs V2,P<001 vs CTX).After CTX+V2 immunization,high titer of anti-VEGF antibody was detected by ELISA and verified by Western blot.Conclusion The therapy of CTX combined with V2 has significant synergistic effect against H22 hepatocellular carcinoma.
RESUMO
Objective To examine the teaching effects of case-based learning in the class of functional experiment. Methods Students (n=139) of five-year clinical medicine specialty were ran-domly divided into control group (n=70) and case group (n=69). The students of control group were taught with traditional teaching method and the case-based learning was adapted in the case group. Namely the clinical cases were led into teaching and the teaching process was completed through case import, problem sets, and the literature review and discussion. The teaching effects were evaluated through questionnaire survey (Analysis by the χ2-test, the test level is 0.05) and the analysis of test scores (Analysis by the t-test, the test level is 0.05). Results The score of the case group was better than the control group in the operation test (P=0.042 0). The total evaluating score and test score were also better in the case group in comparing to the control group (P=0.007 8 or P=0.008 2). As indicated by the questionnaire survey, more than 80%students thought the case teaching method could improve their learning interests and the independent learning abilities. Moreover, the skills of problem analysis and knowledge application were increased through case teaching. Conclusion The teaching effects of case-based learning were superior to the traditional teaching.
RESUMO
In medical colleges, it is difficult to effectively carry out design experiment teach-ing in functional experiment because of the limitation of many factors such as the large number of stu-dents and the shortage of teachers and teaching resources. This study explored the multi-level teaching of designing experiment. Through gradually increasing the difficulty of the teaching content, the center position of the students was improved. Besides, the students' knowledge expanded from books to the subject research frontiers and their awareness of innovation was gradually enhanced. The survey showed that students' satisfaction with the teaching was up to 90% and their self-learning ability was en-hanced. However, it should be noticed that teaching time should be arranged reasonably and the teach-ing process should be supervised in design experiment to ensure the effective experiment teaching.
