Objective To explore the relationship between health literacy （HL）,empowerment and quality of life （QOL） in disabled elderly and their spouses based on the theory of “dyadic coping”. Methods From December 2020 to June 2021,498 disabled elderly and their spouses in Guangzhou,Zhuhai and Shenzhen of Guangdong province were surveyed by sociological data questionnaire,Katz Index ADL Scale,Health literacy Scale for chronic disease patients,Chinese Elders Health Empowerment Scale and Chinese Short Form-36 Health Survey. Spearman correlation analysis and structural equation model were used to analyze the data. Results The median scores of HL,empowerment and QOL of the disabled elderly were 86.00,30.00 and 391.39,respectively. The median scores of HL,empowerment and QOL of the spouses were 93.00,32.00 and 617.28,respectively. Correlation analysis showed that there were positive correlations between all variables（r=0.156~0.657,P<0.05）,except correlation between spouses’ empowerment and QOL of the disabled elders（P=0.91）. The structural equation model showed that the HL of the disabled elderly could affect the QOL directly or indirectly through empowerment （path coefficients were 0.30 and 0.23,P<0.001）,and the model fitted well（GFI=0.811,AGFI=0.788,RMSEA=0.057）. The HL of the disabled elders and their spouses had a positive interaction（path coefficient was 0.47,P<0.001）. The QOL of the disabled elders was positively correlated with the QOL of their spouses（path coefficient was 0.18,P=0.004）. Conclusion The interaction of HL and QOL between the disabled elders and their spouses suggests that the disabled elders and their spouses should not be considered separately under the pressure of disability,which verifies the rationality of the application of “dyadic coping” theory. The disabled elders and their spouses should be educated and empowered together to improve their QOL.

Objective To retrieve relevant evidence of the postoperative home rehabilitation nursing for elderly patients with hip fracture，and provide evidence for clinical nurses to formulate home rehabilitation nursing pro-grams. Methods The relevant evidence of postoperative home rehabilitation nursing for elderly patients with hip fracture was systematically searched from domestic and foreign databases and websites，including clinical decision-making，guidelines，systematic reviews，expert consensuses and evidence summaries，and the search time limit is from the establishment of the databases to Oct.31，2021. There were 2 researchers who evaluated the quality of various literature and extracted recommendations and research conclusions from the included literature. Results A total of 15 articles were involved，including 3 articles on clinical decision-making，3 guidelines，2 systematic reviews，5 expert consensuses，2 evidence summaries. 27 pieces of the best evidence were formed on suitable population，discharge plan，rehabilitation assessment，rehabilitation expectation，exercise strategy，intensive training，health education and health follow-up. Conclusion The best evidence summary for postoperative home rehabilitation nursing in elderly patients with hip fracture was summarized. When applying the evidence，health care professionals should fully consider the specific clinical setting and formulate individualized rehabilitation nursing plans based on the needs and preferences of patients.

Objective To design a special oxygen mouth guard for endoscopy and to evaluate its clinical application effects. Methods The designed special oxygen mouth guard comprises 7 elements（such as mouth pad,nasal and oral oxygen inhalation tubes）. A total of 120 patients with common bile duct stones undergoing endoscopic retrograde cholangiopancreatography at the endoscopy center of a tertiary hospital in Shanghai from January to February 2021 were included,and they were randomly divided into an experimental group and a control group,with 60 patients in each group. In the experimental group,the special oxygen mouth guard was used. In the control group,traditional oxygen tube and mouth guard were used. The wearing time,oxygen saturation（SpO₂） fluctuations,nasal catheter displacement rate and medical staff satisfaction were evaluated and compared between 2 groups. Results The wearing time in the experimental group was（20.58±2.43） s,while it was（27.30±2.89） s in the control group,and the difference was statistically significant（t=-13.795,P<0.001）. The SpO₂ value in the experimental group was 2.00%（1.00%,2.75%）,while it was 3.00%（2.00%,4.00%） in the control group,and the difference was statistically significant（Z=-4.332,P<0.001）. The nasal catheter displacement rate in the experimental group was 0,while it was 18.33% in the control group,and the difference was statistically significant（χ²=-12.110,P=0.001）. The score of medical staff satisfaction in the experimental group was（28.35±1.39）,while it was（26.48±1.56） in the control group,and the difference was statistically significant（t=6.933,P<0.001）. Conclusion The special oxygen mouth guard for endoscopy is easy to wear,and it can reduce the fluctuations in SpO₂ and nasal catheter displacement rate,and improve the medical staff satisfaction and safety of ERCP.
