Objective To compare 3 kinds of preoperative scoring systems used to predict 30-day mortality in a hip fracture population,Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity (POSSUM),Portsmouth modified POSSUM (P-POSSUM) and Estimation of Physiologic Ability and Surgical Stress (E-PASS).Methods A retrospective study was conducted to analyze the aged 654 patients who had undergone surgery for femoral intertrochanteric fracture or femoral neck fracture from January 2010 through June 2014 at our hospital.They were 225 men and 429 women,60 to 103 years of age (average,71.7 years).There were 363 femoral intertrochanteric fractures and 291 femoral neck fractures.Closed reduction and intramedullary nailing was performed in 363 cases,artificial dipolar replacement in 242 cases,and total hip replacement in 49 cases.POSSUM,P-POSSUM and E-PASS scoring systems were used to predict the 30-day mortality.The discrepancy between the predictive risk and the actual observation was analyzed.Results Of the 654 patients,25 died within 30 days after operation.According to POSSUM scoring system,the predictability (observed deaths/POSSUM deaths) was 0.30,showing a significant difference between the predictive deaths and the actual deaths(x2=34.840,P=0.009).According to P-POSSUM and E-PASS scoring systems,the predictability was respectively 0.83 and 1.04,demonstrating no significant differences between the predictive deaths and the actual deaths(P ＞ 0.05).Conclusion P-POSSUM and E-PASS scoring systems may predict 30-day mortality more accurately than POSSUM scoring system in elderly patients undergoing hip fracture surgery.

This paper summarizes the application of health coaching in self-management of patients with cardiovascular diseases. Health coaching can help patients with cardiovascular diseases gain the knowledge, skills, tools, and confidence that they need to become active participants in their self-health and enhance their self-management. The form of health coaching includes motivational interview, self-management support and remote home monitoring. Health coaching can enhance the medication adherence among patients with cardiovascular diseases, promote healthy lifestyles and maintain good psychology in patients, and finally strengthen their self-management. Finally, this paper proposes that China should pay more attention to the health coaching, such as establishing the relevant departments of health coaching, strengthening the training and certification of health coaches through the examination of theory and skills, and exploring the establishment of a technical program for health coaching and intervention that is suitable for China, so that patients with cardiovascular diseases can be benefited.

Objective:To investigate the self-management of elderly chronic heart failure (CHF) patients and to explore the structural equation modeling (SEM) on the influencing factors of self-management behavior among CHF patients so as to provide a basis for constructing the self-management education plan for elderly CHF patients suitable for the characteristics of our country.Methods:From January 2015 to June 2017, The study selected 6 124 elderly patients in 102 hospitals of 16 provinces, cities and autonomous region from 5 areas, east China, west China, south China, north China and central China by random cluster sampling as subjects. All of patients were investigated with the self-management scale of heart failure patients, heart failure knowledge questionnaire, chronic disease self-efficacy scale, self-concept scale and the medica coping modes questionnaire. AMOS 22.0 was used to construct the model on the influencing factors of self-management behavior among CHF patients.Results:The total score self-management of 6 124 elderly CHF patients was [49.00 (43.00, 54.00) ] with 61.25% for the scoring rate. The SEM on the direct or indirect influencing factors of self-management among elderly CHF patients fitted well. The influencing factors of self-management included the per-capita incomes, works, self-care, nations, religious belief, education levels, heart failure knowledge, self-concept, self-efficacy, coping styles.Conclusions:Self-management of elderly CHF patients are in the below average level influenced by different demographers, cultural background and heart failure knowledge. Medical staff should formulate a systematic and individual self-management education plan for elderly CHF patients based on patients' demographic characteristics, cultural background, heart failure knowledge, self-concept and self-efficacy to improve their self-management.

Objective:To construct a scientific and practical micro-course content framework of cross-cultural nursing hospice care from the perspective of attention, relevance, confidence and satisfaction (ARCS) model.Methods:The research team was established in November 2018. Using Delphi method, 16 experts in cross-cultural nursing, hospice care, nursing management, nursing education and other fields were consulted for 3 rounds of correspondence. According to scores of experts, the index weights were calculated to form micro-course content framework of cross-cultural nursing hospice care from the perspective of ARCS model.Results:The positive coefficient of experts surveyed by the questionnaire was 100%, the average value of expert authority coefficient was 0.81. The determined importance values of the first and second level indexes were all greater than 4.00. The coefficient of variation was 0 to 0.12, which were all less than 0.25 and met the requirements. In the end, a content framework containing 3 first-level indexes of professional concepts, professional knowledge and professional skills and 19 second-level micro-course content framework of cross-cultural nursing hospice care were formed.Conclusions:Based on the perspective of ARCS model, the construction process of content framework of the cross-cultural nursing hospice care micro-course is scientific and the setting is reasonable, which has a good guiding significance for the development of training for hospice care nurses.

Objective? To understand the self-management status among elderly chronic heart failure (CHF) patients and to compare the regional differences of self-management. Methods? By random cluster sampling, we investigated 6 124 elderly CHF patients from 102 hospitals in five regions, East China (Jiangxi Province, Shanghai Municipality, Zhejiang Province), West China (Qinghai Province, Xinjiang Uygur Autonomous Region, Shaanxi Province, Gansu Province, Ningxia Hui Autonomous Region, Yunnan Province), South China (Hainan Province, Guangxi Zhuang Autonomous Region), North China (Heilongjiang Province, Inner Mongolia Autonomous Region), Central China (Henan Province, Hubei Province, Hunan Province). The investigation result statistics were carried out and regional differences were compared. Results? The self-management of elderly CHF patients had a low to medium level with 61.25% (49/80) ＜80% for the scoring rate. The scores of East China and Central China were higher and the score of West China was low; the regional differences were statistical (H=59.07, P＜0.01). The score of diet management was highest with 66.67% for the scoring rate (8/12); East China had the highest score, and West China had the lowest score; the regional differences were statistical (H=92.49, P＜0.01). The scoring rate of medication management was 65.00% (13/20) with the highest in East China and low in North China and West China; the regional differences were statistical (H=351.10, P＜0.01). Mental/social adjustment management was poor with 60.00% (12/20) for the scoring rate; the scores of Ease China were higher than those of North and West China; the regional differences were statistical (H=8.84, P＜0.01). Symptom management was the worst with 57.14% (16/28) for the scoring rate; the scores of East and Central China were high;the regional differences were also statistical (H=17.62,P＜0.01). Conclusions? Self-management of elderly CHF patients needs to be improved. Systematic and targeted health education for different regions should be carried out to improve patients' self-management and to reduce the disease burden.

Objective To investigate the application of 3D-printing and digital technology in the preoperative design of internal fixation for intra-articular calcaneal fractures.Methods Thin-layer CT images of bilateral calcanei were collected from 12 patients who had been treated for calcaneal fracture of Sanders type Ⅲ from November 2015 to October 2016.They were 7 men and 5 women,aged from 23 to 53 years (average,38.7 years).The images were uploaded into Mimics software for 3D reconstruction,virtual reduction and digital surgical design.Real-size calcaneal models and navigation modules were produced using 3D printing technology for plate preshaping and surgical simulation.The operations were carried out according to preoperative design.The postoperative calcaneal morphological parameters were evaluated.Comparisons were made between postoperative results and preoperative digital design.Results The operating time for the 12 patients ranged from 60 to 90 minutes,averaging 77.9 minutes.Their follow-ups ranged from 4 to 8 months,averaging 6.2 months.No complications affecting their soft tissues happened.The postoperative B(o)hler angle (32.6° ± 3.6°) and Gissane angle (123.9° ± 9.5°) were significantly improved compared with the preoperative values (12.4° ± 2.1° and 143.9° ± 7.8°) (P ＜ 0.001).The shape of postoperative calcaneus was similar to that of the preoperative reduction model.The internal fixation locations and nail directions were in agreement with the preoperative design.Their average Maryland score was 87.8 and excellent to good rate 91.7％.Conclusion This technique can transform a digital design for intra-articular calcanealfracture into real operation tools to help realize a precise surgical design for such fractures.

Objective:To explore the clinical effect of a modified single-trunk arterialised venous flap in reconstruction of soft tissue defect in hand and foot.Methods:From January 2019 to June 2022, 25 patients with soft tissue defect in hand and foot were treated in the Department of Hand and Foot Plastic Surgery of Lecong Hospital of Shunde in Foshan. The soft tissue defects were reconstructed with a venous flap, of which a single trunk of vein was ligated and then a blood flux of the flap was re-established via a modified single vein trunk. One patient had soft tissue defect in dorsal foot and toes, 3 patients had defects in dorsal hand, 3 patients had defects in 2 digits and 18 patients had defects in single-digit. The sizes of defects were 2.0 cm×1.0 cm-10.0 cm×4.5 cm. The sizes of flaps were 2.0 cm×1.0 cm-12.0 cm×5.5 cm. Donor sites of the 19 cases were directly sutured and 6 were covered by skin grafts. The postoperative follow-ups were conducted at outpatient clinics and via telephone reviews to observe the survival of flaps. Functional recovery of 23 cases whose soft tissue defects in hand were evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. The sensory recovery of flaps was evaluated according to the comprehensive flap scale.Results:All 25 single-trunk venous flaps survived successfully. There were small number of blisters on 5 flaps, due to tissue oedema. One patient lost in follow-up. The other 24 patients had 2-18 months of follow-up. The appearance of flaps was soft and thin, with wear-resistant. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the function recovery were excellent in 12 cases, good in 9 cases and poor in 2 cases. Sensations of the flaps were 90-99 point with an average of 97 point according to the comprehensive flap scale, of which 22 flaps were in excellent and 2 in good.Conclusion:The method of ligation of single vein-trunk to make a arterialised venous flap is a simple surgical procedure. There are many selections of donor site with minimum damage. It is an effective method and with satisfactory outcomes.
