To solve the problems of insufficient airway opening, insufficient or excessive ventilation, ventilation interruption, and the rescuer's physical strength during the process of cardiopulmonary resuscitation (CPR) outside the hospital and in the hospital, and to ensure the accuracy of ventilation frequency rate and tidal volume. Zhongnan Hospital and School of Nursing, Wuhan University, jointly designed and developed a smart emergency respirator with open airway function, that has been granted National Utility Model Patent of China (ZL 2021 2 1557989.8). The device is structured of pillow, pneumatic booster pump and mask. It can be used simply by plugging the pillow under the patient's head and shoulder, turning on the power supply and wearing the mask. The smart emergency respirator can quickly and effectively open the patient's airway and give accurate ventilation with adjustable ventilation parameters. The default settings are 10 times/min in respiratory rate and 500 mL in tidal volume. The whole operation does not require the operator have professional operation ability, which can be independently applied used in any cases without oxygen source or power supply, therefore, the application scenario has no limit. The device has the advantages of small size, simple operation and low production cost, which can reduce human source, save physical strength and significantly improve the quality of CPR. The device is suitable for respiratory support in multiple scenes outside and inside the hospital, and can significantly improve the success rate of treatment.

Objective:To retrieve and select the available evidence on preventing the fall on the home-based elderly people and summarize the best available evidence.Methods:The BMJ Best Practice, UpToData, Registered Nurses′ Association of Ontario (RANO), National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Joanna Briggs Institute (JBI), Cochrane Library, and complementally the Center for Disease Control and Prevention(CDC), PubMed、CNKI and SinoMed were searched to collect literatures including guideline, evidence summary, best practice information sheet, recommended practice, systematic review/Meta-analysis.Results:13 articles were selected, including 6 guidelines, 1 clinical decision, 1 evidence summary, 5 systematic reviews/Meta-analysis. Finally, 8 items of best evidence were summarized.Conclusions:Healthcare workers should appropriately consult the best evidence to prevent falling and falling injuries for the home-based elderly people, and finally improve their health-related quality of life.

Objective To evaluate the curative effect of traditional Chinese medicine fumigation combined with conventional therapy for the diabetic foot. Methods A total of 90 patients with type 2 diabetes who were treated in the hospital from March 2015 to August 2017 were enrolled in this study. On the basis of conventional treatment, the treatment group received the traditional Chinese medicine fumigation, while the control group received warm water fumigation. The total limb popliteal artery, femoral artery, posterior tibial artery and dorsalis pedis artery and a score of symptoms and signs were compared between two groups after 4 weeks. Results The total effective rate of the treatment group was 73.3% (33/45), while the control group was 53.3% (24/45), and the difference was statistically significant (χ2=3.876, P=0.049). After treatment, total limb femoral artery(58.38 ± 12.53 cm/s vs.51.94 ± 11.62 cm/s,t=2.528),popliteal artery(43.87 ± 9.46 cm/s vs.39.87 ± 8.28 cm/s,t=2.134),posterior tibial artery(35.72 ± 8.29 cm/s vs.30.89 ± 8.51 cm/s,t=2.725),dorsalis pedis artery (26.82 ± 8.10 cm/s vs.22.87 ± 7.39 cm/s,t=2.413)of the treatment group were significantly higher than those of the control group(P<0.05).The main symptom score(2.0 ± 1.5 vs.4.1 ± 2.1,t=5.419),sub syndrome score(3.1 ± 1.8 vs.5.1 ± 2.3,t=4.692),tongue and pulse condition score(1.8 ± 0.8 vs.2.4 ± 0.6,t=4.277)of the treatment group were significantly lower than those of the control group (P<0.01). Conclusions The traditional Chinese medicine fumigation combined with conventional therapy could improve the lower extremity blood flow status in diabetic foot patients and clinical symptoms.
