Objective To compile the"expert consensus on preventive and management of exposure keratopathy"(hereinafter referred to as"consensus"),aiming to standardize and promote the prevention of exposure keratopathy(EK)in medical institutions at different levels.Methods The evidence-based methods were used to retrieve,evaluate and summarize evidence in this field according to the level of evidence,and relevant recommendations and research conclusions were extracted,and the first draft of consensus was formed.After 2 rounds of Delphi expert letters and expert meetings,combined with evidence and expert opinions,the consensus content is written,adjusted and modified,and recommendations were made.Results 58 experts were invited to participate in the consultation.The expert positive coefficient was 100％;the expert judgment basis of the 2 rounds were 0.940 and 0.936;the degree of familiarity of the 2 rounds were 0.779 and 0.797;the coefficient of authority of the 2 rounds were 0.859 and 0.866.The Kendall W coefficients of the 2 rounds of inquiry were 0.099 and 0.117,and the difference was statistically significant(P＜0.05).The consensus includes 5 aspects of EK:risk factors,assessments,protection measures,symptom management and training and management.Conclusion The consensus was based on the existing evidence and clinical practical requirements and recommendations of experts in the field.Consensus can provide guidance for clinical nursing staff in prevention,nursing and management of EK effectively.

Objective:To explore the application effect of data envelopment analysis(DEA)model in the safety and quality management of ventilators in intensive care units.Methods:Based on the Chanis-Cooper-Rhodes(CCR)dual model,by adding constraints,the input-oriented Bank-Carnes-Cooper(BCC)model was constructed to construct the DEA model.Among the 124 related items in the DEA model,20 high-level related items were identified to carry out ventilator quality control management related to clinical service efficiency.A total of 33 ventilators in clinical use in the intensive care unit(ICU)of Jiangsu Province Hospital from October 2021 to September 2023 were selected.Among them,the ventilators used from October 2021 to September 2022 were managed by traditional quality control management methods,and the ventilators used from October 2022 to September 2023 were managed by DEA model.The satisfaction scores,management quality scores and clinical efficiency scores of participants in ventilator use management were compared between the two management methods.Results:The satisfaction scores of medical staff,patients and equipment engineers for ventilator management using the DEA model management method were(96.68±2.25)points,(96.32±2.18)points and(95.66±2.54)points,respectively,which were higher than those of the traditional quality control management method,the difference was statistically significant(t=10.940,15.220,6.674,P＜0.05).The average scores of ventilator operation performance,inspection operation safety and timeliness using DEA model management method were(4.44±0.31)points,(4.53±0.37)points and(4.61±0.36)points,respectively,which were higher than those of the traditional quality control management method,the difference was statistically significant(t=12.692,14.979,17.025,P＜0.05).The average scores of ventilator work efficiency,ventilator response time efficiency and ventilator treatment efficiency using the DEA model management method were(4.49±0.32)points,(4.75±0.35)points and(4.68±0.32)points,respectively,which were all higher than those of the traditional quality control management method,with statistically significant differences(t=21.179,16.785,16.347,P＜0.05).Conclusion:The application of the DEA model in the management of ventilators in ICU can improve the efficiency of ventilator clinical service,improve the satisfaction of ventilator management personnel and the quality of ventilator management.

Ferroptosis is a kind of programmed cell death, involves multi-molecular and multi-signaling pathways, and the core processes is iron overload and lipid peroxidation. It affects cancer, neurological disease, cardiovascular disease, digestive system disease, and many other diseases. While, ischemia-reperfusion injury is an extremely complex pathological process, including ischemia-reperfusion injury of the heart, brain, liver and kidney, etc., which often occurs in shock, organ surgery and organ transplantation, seriously affecting human health, and there is no effective radical treatment. However, ferroptosis is closely related to ischemia-reperfusion injury so that it is possible to find the prevention and treatment measures of ischemia-reperfusion injury by exploring the internal relationship between them. Therefore, the author tries to summarize the signaling pathways of ferroptosis, and explores the relationship between ferroptosis and ischemia-reperfusion injury of heart, brain, liver and kidney by moderating the ferroptosis targets properly to find the effective ways to treat cancer, improve inflammation and relieve other diseases.

Objective To evaluate the clinical application of ultrasonic integrated backscatter(IBS) parameters and assess the lesion of myocardium in patients with different left ventricular geometric patterns.Methods Four groups were analyzed according to left ventricular mass index and relative wall thickness in 146 essential hypertensive patients,including group 1(n=64),group 2(n=18),group 3(n=20),group 4(n=44).Myocardial IBS,normalized IBS (IBS%),cyclic variation of IBS(CVIB) and transmural gradient of IBS(TGIB) of interventricular septum(IVS) and post wall(PW) were measured in 4 groups and 32 normal control subjects.Results Among the four groups,IBS% of IVS and PW were the highest in group 3 ( 53.6%? 9.8%, 52.8%? 8.3%,respectively) and next higher in group 2 ( 49.8%? 7.2%, 49.6%? 9.0%,respectively) and group 4 ( 49.0%? 7.7%, 48.9%? 8.2%,respectively),and was low in group 1 ( 42.3%? 8.4%, 41.8%? 9.1%,respectively) (P
