RESUMO
Objective:To explore the application of Sojump in clinical teaching assessment of nursing students in operating room and to evaluate its effect.Methods:The graduation examination results of nursing students in clinical practice in the operating room of Second Affiliated Hospital of Medical College of Shantou University from 2017 to 2019 were collected, the results of 2017-2018 as the control group, and those of 2018-2019 as the observation group. The control group took the paper handwriting test, and the observation group took the electronic Sojump test, and the two-year graduation examination results were compared. A questionnaire survey was conducted to investigate the nursing students' satisfaction with the teaching work of the teachers in 2018-2019, and the teachers' feelings of the teachers' training was investigated with the questionnaire. SPSS 22.0 was used for t test. Results:The graduation examination scores of all educational levels in the observation group were higher than those in the control group, with statistical differences between the two groups ( P<0.05). The satisfaction rate of nursing students who did not understand the contents of the questionnaire and studied again was 98.19%, and the teachers' satisfaction rate of automatic marking of Sojump test was 100%. Conclusion:Sojump is easily and efficiently operational, paperless, targeted teaching, which can promote teaching by evaluation, and reach high satisfaction of nursing students and teachers, worthy of promotion in clinical teaching.
RESUMO
Objective To compare the actions of Longbie Capsules and bone marrow mesenchymal stem cell (BMSC)transplantation in repairing the damaged cartilage of knee osteoarthritis(KOA)rats. Methods Thirty-six rats aged 4-6 weeks old were induced into KOA model(bilateral knees)by collagenase injection method. All of the modeled rats were randomly divided into model group(intragastric administration of normal saline), BMSC transplantation group(giving tail vein injection of 1 ×106 of BMSCs per time, 2 times every week), and Chinese medicine group (intragastric administration of Longbie Capsules of 7.5 g·kg-1·d-1),12 rats in each group. Six weeks later,the cartilage of rat bilateral knees was taken out. The pathological changes of cartilage were observed by hematoxylin-eosin(HE) staining method, and the protein and mRNA expression levels of Col2a1, X-linkedinhibitor of apoptosis protein (XIAP), HuR in rat knee cartilage were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR), respectively. Results The HE staining results showed that the cartilage tissue surface was rough with more cracks, and the cartilage cells gathered with the cytoplasm collapsed and arranging disorderly in the model group. The number of chondrocytes was increased and cell surface was flat,and the cracks of the cartilage were decreased with the chondrocytes arranging uniformly in Chinese medicine group and BMSC transplantation group compared with the model group. The results of immunohistochemistry and qPCR detection showed that in Chinese medicine dosage group and BMSC transplantation group, the protein and mRNA expression levels of Col2a1,XIAP and HuR were significantly higher than those in the model group (P<0.05 or P<0.0001), but there was no significant difference between the two medication groups(P>0.05). Conclusion Longbie Capsules and BMSC transplantation can promote the secretion of Col2a1 in the cartilage tissue of KOA rats,improve cartilage, and their mechanism may be related with up-regulating apoptosis-related proteins HuR and XIAP.
