Objective To investigate the effect of intermittent pneumatic pressure pump on the formation of deep venous thrombosis of lower extremity in elderly patients undergoing thoracotomy. Methods Fifty patients undergoing thoracic surgery were managed with intermittent pressure inflation pump besides general preventive measures. The pre-and postoperative blood flow in the lower extremity and incidences of deep venous thrombosis were compared. Result The differences in blood flow in the lower extremity and incidences of deep venous thrombosis were not statistically significant (P>0.05). Conclusion Intermittent pneumatic pressure pump can promote pulsatile blood flow in the lower extremity so as to effectively prevent formation of deep venous thrombosis in elderly patients after thoracotomy.

Objective To explore the mediating effect of nurse professional identity between the practice environment and safety behavior,in order to provide references and bases for managers to formulate scientific,reasonable and standardized interventions for nurse safety behavior.Methods A total of 1381 nurses from 5 tertiary general hospitals in Beijing were adopted for investigation from May to June 2022 by convenience sampling method.They were investigated with general information questionnaire,Nurse Safety Behavior Questionnaire,Nursing Practice Environment Assessment Scale and Nurse Professional Identity Assessment Scale.The structural equation model was used to analyze the mediating effect of nurse professional identity between practice environment and safety behavior.Results Finally,1303 nurses participated in the survey.The total scores of nurse safety behavior scale,nursing practice environment assessment scale and nurse professional identity scale were 59.0(56.0,60.0)points,3 441.0(3 066.0,3 586.0)points,131.0(115.0,150.0)points,which were all above the medium level.Nurse safety behavior was significantly positively correlated with nurse professional identity and the nurse practicing environment assessment(r=0.516,0.421,P<0.01),and was significantly positively correlated with the scores of all dimensions(P<0.01).The practice environment and professional identity can directly and positively affect the level of nurse safety behavior.The mediating test shows that nurse professional identity plays a partial mediating effect between the practice environment and safety behavior,and the mediating effect is 0.184,accounting for 46.11%of the total effect.Conclusion In this study,nurse professional identity is a mediator between the practice environment and safety behavior.Nursing managers should pay attention to the cultivation of nurses'professional identity and optimize the working environment of clinical nurses,so as to improve nurse safety behavior and ensure the safety of patients.

Objective To construct a training program for retuming to work after delivery based on Morrison's job adaptation theory in operating room nurses and to explore its application effect.Methods On the basis of literature research and Delphi expert consultation method,a training program of postpartum return of operating room nurses was constructed.From August 2021 to December 2022,the preliminary application of this research program was carried out,with 6 cases in an experimental group and 5 cases in a control group.The differences between the 2 groups were compared by Job Adaptation Scale,Psychological Resilience Scale and satisfaction evaluation,and the application effect was evaluated.Results After 2 rounds of correspondence,a training program for postpartum return of operating room nurses was formed,which included 4 first-level indicators(role adaptation,task adaptation,environment adaptation and cultural adaptation),and 32 second-level indicators.The authority coefficients of the 2 rounds of correspondence consultation were 0.908 and 0.917,and the Kendall W coefficients were 0.224 and 0.206,respectively(both P<0.001).The preliminary application results showed that there were statistically significant differences in job adaptation and satisfaction evaluation between the 2 groups(both P<0.05).There was no significant difference in psychological resilience score between groups(P>0.05).Conclusion The postpartum retum training program for operating room nurses established in this study is scientific and practical to a certain extent.In the future,samples can be expanded and multi-center studies can be carried out to further test the practicability and effectiveness of the program.

Diabetic mellitus (DM) is a common degenerative chronic metabolic disease often accompanied by severe cardiovascular complications (DCCs) as major causes of death in diabetic patients with diabetic cardiomyopathy (DCM) as the most common DCC. The metabolic disturbance in DCM generates the conditions/substrates and inducers/triggers and activates the signaling molecules and death executioners leading to cardiomyocyte death which accelerates the development of DCM and the degeneration of DCM to heart failure. Various forms of programmed active cell death including apoptosis, pyroptosis, autophagic cell death, autosis, necroptosis, ferroptosis and entosis have been identified and characterized in many types of cardiac disease. Evidence has also been obtained for the presence of multiple forms of cell death in DCM. Most importantly, published animal experiments have demonstrated that suppression of cardiomyocyte death of any forms yields tremendous protective effects on DCM. Herein, we provide the most updated data on the subject of cell death in DCM, critical analysis of published results focusing on the pathophysiological roles of cell death, and pertinent perspectives of future studies.
