After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Objectives:To establish the Chinese Healthy Lifestyle Index(CHLI),which can be applied to comprehensively assess healthy level of lifestyle among Chinese population.Methods:Potential indicators were screened through literature review.Enrolled indicators were determined by the Delphi expert consultation method and the weight of the indicator was assessed by the analytic hierarchy process(AHP).Finally,the CHLI was obtained though weighted sum.Results:In both rounds of correspondence,the positive coefficients were 92.9% and 93.8%,and the expert authority coefficients were 0.846±0.027 and 0.861±0.030,respectively.The coordination coefficients Kendall's W of the importance scores on primary/secondary indicators were 0.482/0.451 and 0.535/0.557 for the first and second round of consultation,respectively(all P<0.001),indicating a good coordination between expert opinions.The final index system of CHLI includes 5 primary indicators and 28 secondary indicators.Regarding the weights of primary indicators,the highest weight was assigned to diet(0.239),followed by psychological health(0.220),physical activity(0.198),nicotine exposure(0.175)and sleep health(0.167).The combined weights of the secondary indicators ranged from 0.009 to 0.198.The consistency ratios of the AHP judgment matrices were all less than 0.1,indicating the results were credible.Conclusions:The CHLI can be used to comprehensively evaluate the healthy level of lifestyle among Chinese population.

Objective:To clarify the complex network structure between self-management levels and supportive care needs of patients undergoing maintenance hemodialysis, utilizing network analysis methods to identify the core and bridging nodes among the variables, thereby defining targets for nursing interventions to implement more precise care strategies.Methods:A cross-sectional survey was conducted from May to November 2023 among 302 outpatient maintenance hemodialysis patients at the hemodialysis centers of two healthcare institutions in Harbin (the Second Affiliated Hospital of Harbin Medical University and Heilongjiang Changjiang Nephrology Specialist Hospital). This involved the use of general information questionnaires, the Hemodialysis Patient Self-Management Scale, and the Supportive Care Needs Scale for Hemodialysis Patients. R language was employed for the network analysis.Results:A total of 300 valid questionnaires were collected, including 186 males and 114 females, with an age range of 23 to 88 years (mean age 55.00 ± 13.78 years). The scores for the dimensions of self-management among dialysis patients were as follows: problem-solving (3.38 ± 0.63), execution of self-care (3.16 ± 0.52), partnership (2.56 ± 0.69), and emotional processing (1.89 ± 0.63). The scores for the dimensions of supportive care needs among dialysis patients were: physiological needs (2.82 ± 1.08), psychological needs (1.51 ± 1.02), social needs (1.97 ± 1.07), emotional needs (1.67 ± 1.12), spiritual needs (2.22 ± 0.77), informational needs (2.83 ± 1.08), and practical needs (2.82 ± 1.03). In network analysis, the strongest intensity was found in the execution of self-care (1.753), and the highest closeness was in psychological needs (0.017). The top three dimensions ranked by bridge strength were social needs (1.463), partnership (1.462), and execution of self-care (1.384). The root mean square error was lowest for psychological needs (0.518) and emotional needs (0.538). The stability and accuracy of the network structure were found to be good.Conclusions:The key intervention targets for nursing care in maintenance hemodialysis patients were identified as executing self-care, psychological needs, emotional needs, and social needs. Among these, executing self-care served as the core intervention focus, while psychological and emotional needs had dominant influences, and social needs exhibited the strongest bridging role. Nursing staff should prioritize these key targets and tailor personalized comprehensive nursing intervention plans to enhance patients′self-management levels and fully meet their care needs.

Objective To explore the characteristics of the potential categories of traumatic psychological reactions in ICU patients and analyze the influencing factors of different potential categories,in order to provide ideas for the implementation of scientific and effective personalized intervention in the future.Methods A convenience sample of 300 patients treated in the ICU of a hospital from May 2023 to February 2024 was surveyed.The used instruments included a general information questionnaire,the Social Support Rating Scale,the Brief Resilience Scale,the Acute Stress Disorder Scale,and the Simplified Chinese version of the Post-Traumatic Growth Inventory.Data were analyzed using multivariate Logistic regression.Additionally,a purposive sampling method was used to conduct semi-structured interviews with 12 ICU patients,and the interview data were analyzed by interpretative phenomenological analysis.Results Quantitative research results showed that the traumatic psychological responses of ICU patients were categorized into 4 latent classes,including Trauma-Dependent Type(17.3％),Smooth-Transition Type(36.0％),External-Support Growth Type(25.3％),and Internal-Rooted Growth Type(21.3％).Factors influencing these responses included age,educational level,social support,psychological resilience,household income,and the number of used hormone medications(P＜0.05).Qualitative research results showed that 4 core themes were identified,including immersion in psychological trauma,rational cognition and acceptance of reality,seeking external support for personal growth,and independent exploration of inner self.Influencing factors included age,income level,history of major illness or ICU treatment,level of disease awareness,presence of underage children,and individual capacity for rumination.The quantitative and qualitative results were mutually corroborative and complemented each other.Conclusion The acute stress response of ICU patients is obvious,and there are multiple characteristics in the potential categories of traumatic psychological response,suggesting that medical and nursing staff can identify the characteristics of various types and influencing factors early,formulate personalized intervention programs,and promote their post-traumatic growth.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective: To investigate the clinical value of blood routine tests (RT) and coagulation function in differential diagnosis of mild and severe patients infected with bunyamwera virus. Methods: Twenty-five mild patients and 25 severe patients infected with bunyamwera virus were selected and their blood RT and coagulation function tests were performed. Results: The earliest prothrombin time (PT-early) and activated partial thromboplastin time(APTT-early) were significantly lower than those of severe patients(t=-2.43, P<0.05; t=-2.53, P<0.05). The lowest values of white blood cells (WBC-low) of mild patients were significantly higher than those of severe patients (t=5.66, P<0.01). The highest value of D-dimer (DD-high) of mild patients were significantly lower than that of severe patients (z=1.35, P<0.05). When mild patients values were set as outcome variable, AUC of APTT-early was the highest (AUC=0.713, P<0.05). When values of severe patients were set as outcome variable, AUC of DD-high was the highest (AUC=0.874, P<0.01). Conclusions APTT-early and DD-high are suitable for differential diagnosis of mild and severe patients infected with bunyamwera virus.
