Objective:To establish the standard of nursing quality in bone oncology department, and provide the basis for scientific evaluation of nursing quality in bone oncology department.Methods:On the theoretical basis of Donabedian′s three-dimensional quality model of "structure-process-outcome", and through literature review and semi-structured interview method, the "evaluation index of nursing quality in bone oncology department" was preliminatively formulated from November 2022 to June 2023. The Delphi method was used to select 31 experts from 31 third-level A hospitals and nursing colleges in 27 provinces or municipalities across the country for two rounds of correspondence consultation. The criteria were screened and modified to determine the evaluation criteria of nursing quality in bone tumor specialty.Results:The questionnaire recovery rate of 2 rounds of expert consultation was 100.00%, the authority coefficient of 2 rounds of expert consultation was 0.93, and the coefficient of variation of 1, 2 and 3-grade standards were all less than or equal to 0.25. The Kendall′s coefficient of concordance of the primary standards of the two rounds of expert consultation were both 0.088, in the secondary standards were 0.103 and 0.140, in the tertiary standards were 0.119 and 0.110. Through 2 rounds of expert letter consultation, the evaluation criteria for the quality of care in bone tumor specialties were divided into three levels, including 3 primary standards (structural quality criteria, process quality criteria and outcome quality criteria), 21 secondary standards and 80 tertiary standards.Conclusions:The construction process of nursing quality standard in bone oncology department is scientific and reliable, reflecting specialty characteristics, and can provide scientific basis for the evaluation of nursing quality in bone oncology department and standardize nursing behavior.

Acute liver failure(ALF)is one of the most critical liver diseases in clinical practice and seriously affects the life and health of Chinese people.Due to its high morbidity and mortality rates,unclear pathogenesis,and limited treatment methods,ALF has become a major problem that needs to be solved urgently in the field of liver diseases.In recent years,more and more studies have shown that endoplasmic reticulum stress is a key biological process in the progression of ALF,and the IRE1α/TRAF2/JNK pathway,as a part of endoplasmic reticulum stress signaling,plays a role in amplifying inflammatory response,promoting hepatocyte apoptosis,and inhibiting liver regeneration ability during the progression of diseases.As a traditional treasure of China,traditional Chinese medicine has become a research hotspot in search for effective prevention and treatment drugs for ALF from monomers of Chinese herbs.This article elaborates on the mechanism of action of the IRE1α/TRAF2/JNK pathway in the progression of ALF and summarizes the potential value of several monomers of Chinese herbs in regulating this pathway,such as salidroside,Fructus Broussonetiae,Fructus Psoraleae+Schisandra chinensis,baicalein,genipin,kaempferol,resveratrol,sea buckthorn polysaccharide extract,and luteol,in order to provide a reference for further research and clinical practice of ALF.

Objective:To observe and analyze depression-like behavioral performances of mouse models of vitiligo.Methods:Fifteen female C57BL/6 mice aged about 9 weeks were modeled for vitiligo. Whether the mouse models of vitiligo were successfully constructed or not was determined by macroscopy and full-thickness epidermal immunofluorescence staining of mouse tail tissues on day 23 after the start of the experiment; on day 8 (pre-modeling stage) and day 21 (early modeling stage), the elevated plus maze test and the open field test were used to evaluate the behavioral performances of the mice, including the number of entry into the open arms, percentages of time spent in the open arms, percentages of time spent in the central area and total distance traveled, aiming to assess whether depression-like behaviors were exhibited in the mouse models of vitiligo. To further clarify the degree of the impact of vitiligo modeling on the depression-like state in mice, 20 female C57BL/6 mice were equally divided into 2 groups: vitiligo modeling group and vitiligo modeling + chronic restraint stress group; the mice in the vitiligo modeling + chronic restraint stress group were subjected to chronic restraint stress on day 9, that is, these mice were placed in centrifuge tubes and restrained for about 6 hours every day for 28 consecutive days; on days 7, 22, 29 and 38 after the start of vitiligo modeling, the above-mentioned behavioral indicators were determined by the elevated plus maze test and open field test in the 2 groups. Repeated measurement data in a single group were compared before and after treatment by using paired t-test, and repeated measurement data at multiple time points were compared by using two-way repeated measures analysis of variance. Results:By macroscopy, the mice gradually developed well-defined white patches on the tail skin during vitiligo modeling, which were similar to the clinical manifestations of vitiligo patients; on day 23, full-thickness epidermal immunofluorescence staining of the mouse tail tissues was conducted and showed obvious infiltration of CD8 + T cells and a decrease in the number of Melan-A-positive epidermal melanocytes under a laser confocal microscope, which were consistent with typical pathological characteristics of vitiligo; based on the macroscopic results and immunofluorescence findings, a total of 12 mouse models of vitiligo were successfully constructed on day 23. The elevated plus maze test showed that the number of entry into the open arms and the percentages of time spent in the open arms were significantly lower in the 12 mouse models of vitiligo on day 21 (2.33 ± 1.78 times, 5.01% ± 5.27%, respectively) than in those on day 8 (10.75 ± 2.30 times, 29.20% ± 12.48%, t = 9.63, 6.36, respectively, both P < 0.001) ; the open field test showed that the percentages of time spent in the central area and total distance traveled were also significantly lower in the mouse models on day 21 (2.31% ± 1.53%, 2 518.31 ± 528.38 cm, respectively) than in those on day 8 (4.47% ± 2.65%, 3 533.45 ± 465.47 cm, t = 2.40, 5.47, P = 0.036, < 0.001, respectively). In the chronic restraint stress test, a total of 14 mouse models of vitiligo were successfully constructed on day 23, including 5 in the vitiligo modeling group and 9 in the vitiligo modeling + chronic restraint stress group. There were no significant differences in the number of entry into the open arms, percentages of time spent in the open arms, percentages of time spent in the central area, and total distance traveled between the vitiligo modeling group and the vitiligo modeling + chronic restraint stress group on days 7, 22, 29, and 38 ( F = 0.21, 0.20, 0.46, 2.35, P = 0.889, 0.893, 0.719, 0.134, respectively) ; moreover, all the above indicators significantly changed over time (all P < 0.001), except for the total distance traveled ( P = 0.422) . Conclusion:The mouse models of vitiligo developed depression-like behavior at the early modeling stage, and the degree of depression could not be further deepened by chronic restraint stress on the basis of vitiligo modeling.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective To develop exercise programs for patients with total hip replacement at different stages in order to promote postoperative rehabilitation and functional recovery.Methods According to the"6S"evidence pyramid model,using computer,a systematic search was conducted using computer-based top-down methods across BMJ Best Practice,Up To Date,the Joanna Briggs Institute evidence-based practice database(JBI),the Centre for Evidence-Based Healthcare,the National Institute for Health and Care Excellence(NICE)website,the Guidelines International Network(GIN),the National Guideline Clearinghouse(NGC),the Scottish Intercollegiate Guidelines Network(SIGN),Medlive,Cochrane Library,Embase,PubMed,CINAHL,Web of Science,China National Knowledge Infrastructure(CNKI),China Biomedical Literature Service System,Wanfang Data Knowledge Service Platform,and VIP Database,to select literature related to exercise for patients undergoing total hip replacement.Three researchers independently assessed these documents and extracted evidence to preliminarily form exercise programs.The Delphi method was used to further validate the scientific and practical aspects of the exercise programs by two rounds of consultation.Results Specific exercise programs for patients undergoing total hip replacement were developed for the preoperative stage,postoperative 1(within 1 week after operation),postoperative stage 2(2-6 weeks after operation),and postoperative stage 3(7-12 weeks after operation),with toatal 41 items.Conclusion The exercise programs developed in this study are scientifically sound and reasonable.They can provide reference for medical staff and patients in related fields.

Objective:This paper examines the access control mechanisms of a big data platform and explores its integration with the ChatGPT artificial intelligence platform for nursing management. The aim was to pilot a self-monitoring and follow-up big data platform for valve disease patients in the Northeastern region of China and assess its effectiveness, providing healthcare professionals with a more practical follow-up tool.Methods:Convenience sampling was used to select 32 patients who underwent mechanical valve replacement surgery or postoperative follow-up at the affiliated hospital of North Sichuan Medical College between January and October 2022 by a retrospective study, were taking oral warfarin anticoagulant therapy, and were willing to use the platform. Based on their platform usage data from November to December 2022, the 32 patients were divided into two groups according to their INR compliance rates: a high compliance group (16 patients) and a low compliance group (16 patients). Evaluate the operational effectiveness of the platform and its impact on patient anticoagulation efficacy based on its usage frequency and INR value compliance rate.Results:The number of login times and INR values written by patients in the high-standard-rate group were (11.31 ± 3.38) and (7.00 ± 1.63) times respectively, which were higher than those in the low-standard-rate group (9.44 ± 3.39) and (6.06 ± 1.88) times, the difference were not statistically significant (all P>0.05). The number of INR values written within the normal range and the number of occurrences of warning values by patients in the high-standard-rate group were (6.38 ± 1.50) and 1.00(0, 2.00) times, which were different than that in the low-standard-rate group (4.05 ± 1.57) and 2.00(2.00, 3.50) times, the differences were statistically significant ( t = 4.26, Z = - 2.22, P<0.05). Conclusions:The self-monitoring and follow-up big data platform for patients after artificial mechanical valve replacement equipped with ChatGPT can optimize and standardize the nursing follow-up workflow, improve nursing work efficiency, reduce the workload of medical staff. At the same time, it provides a better self-management platform for patients after artificial mechanical valve replacement. Assist patients in monitoring INR values and predicting possible changes in their condition, providing corresponding warnings and recommendations helps patients better participate in self-anticoagulation management, and improves the quality of life of patients.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
