Analysis of the Effect of High-Simulation Teaching on Nursing Students' Learning of Nursing Knowledge on Double J Tubes after Ureteral Soft Scope Lithotomy.

OBJECTIVE: To study the effect of high-simulation teaching on nursing students' learning knowledge related to stoma tube care after ureteral flexible mirror lithotripsy. METHODS: A total of 80 nursing students who were admitted to our hospital from January 2020 to December 2022 were selected as the study objects. They were divided into the control group (traditional teaching) and observation group (high-simulation teaching based on traditional teaching) in accordance with teaching method. General demographic information and specialty theory, Objective Structured Clinical Examination, Chinese Critical Thinking Disposition Inventory, Teaching Quality Evaluation Scale and System for Evaluation of Teaching Qualities scores were collected from both groups of nursing students. Data were analysed with t- and chi-square tests. RESULTS: The general demographics of the two groups were not statistically significantly different (p > 0.05). No significant differences in examination scores, clinical skills, thinking skills, teaching quality and nursing students' satisfaction were found between the two groups before teaching (p > 0.05). Examination scores, clinical skills, thinking skills, teaching quality and nursing students' satisfaction were higher in the observation group than in the control group after teaching (p < 0.05). CONCLUSIONS: High-simulation teaching can effectively improve theoretical and clinical skill examination results, strengthen critical thinking, and improve teaching quality and nursing students' overall satisfaction with teaching. Therefore, it has application value.

Emodin alleviates lung ischemia-reperfusion injury by suppressing gasdermin D-mediated pyroptosis in rats.

BACKGROUND: Pyroptosis refers to programmed cell death associated with inflammation. Emodin has been reported to alleviate lung injuries caused by various pathological processes and attenuate ischemia-reperfusion (I/R) injuries in diverse tissues. METHODS: Lewis rats were assigned into the sham, the I/R, and the I/R + emodin groups. Emodin and phosphate-buffered saline were intraperitoneally injected into rats of the emodin group and I/R group for 30 min, respectively. These rats were then subjected to left thoracotomy followed by 90-min clamping of the left hilum and 120-min reperfusion. Sham-operated rats underwent 210-min ventilation. Lung functions, histological changes, lung edema, and cytokine levels were assessed. Protein levels were measured by western blotting. Immunofluorescence staining was conducted to evaluate pyroptosis. RESULTS: Emodin alleviated the I/R-induced lung dysfunction, lung damages, and inflammation. Protective effects of emodin against I/R-mediated endothelial pyroptosis was observed in vivo and in vitro. Mechanistically, emodin inactivated the TLR4/MyD88/NF-κB/NLRP3 pathway. CONCLUSION: Emodin attenuates lung ischemia-reperfusion injury by inhibiting GSDMD-mediated pyroptosis in rats.
