Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Objective To explore the mediating effect of psychological resilience between perceived spousal support and dignity loss in breast cancer patients.Methods A convenience sampling method was employed,involving 377 breast cancer patients who met the study criteria and received treatment at a tertiary oncology hospital in Yunnan Province from March to September 2023.Data were collected using a general information questionnaire,the Dignity Scale,the Perceived Spousal Support Scale,and the Psychological Resilience Scale.Data analysis was conducted using IBM SPSS 26.0 software.Results The scores for dignity loss,perceived spousal support,and psychological resilience of breast cancer patients were(41.72±6.77),(100.42±6.93),and(75.27±8.50),respectively.Pearson correlation analysis showed that dignity loss was negatively correlated with both perceived spousal support and psychological resilience(r1=-0.568,r2=-0.640,both P＜0.05).Mediation effect analysis indicated that psychological resilience had a mediating effect between perceived spousal support and dignity loss,with a value of-0.320(95％CI-0.409 to-0.246),accounting for 57.1％of the total effect.Conclusion The dignity of breast cancer patients in this study is in a state of mild loss,and psychological resilience plays a partial mediating role between perceived spousal support and dignity loss.This suggests that clinical medical staff should pay attention to the spousal support situation of breast cancer patients,provide timely guidance and health education to spouses,enhance the level of support from spouses,and strengthen the confidence and capability of couples in jointly coping with the disease,thereby alleviating dignity loss in breast cancer patients and improving their quality of life.

Objective To systematically evaluate the incidence and influencing factors of falls in adult cancer patients,and provide evidence support for early identification and prevention of falls.Methods Eight Chinese and English databases,including PubMed,Embase,CNKI,and Wanfang Database,were searched by computer.The databases were established until January 2024 and included in cross-sectional,cohort,and case-control studies based on the incidence and/or influencing factors of falls in adult cancer patients.Two researchers independently screened and reviewed literature,evaluated literature quality,and extracted data before conducting meta-analysis using RevMan 5.4 software.Results A total of 19 articles were incorporated into the research,with a total sample population size of 70508 cases.The results showed that the incidence of comorbid falls in adult tumor patients was 23.0%(95%CI 0.23,0.24).Age,female,low education level,fall history,fall fear,middle and late stage of tumor,tumor type(breast cancer,reproductive system tumor,prostate cancer),comorbidity,chemotherapy,radiotherapy,multiple drugs(n≥5),drugs(antidepressants,antipsychotics,sedatives and hypnotics),related symptoms(fever,peripheral neuropathy,fatigue,depression),malnutrition,low weight,cognitive dysfunction,balance disorders,gait abnormalities,and low ability of daily living were the influencing factors for falls of adult tumor patients.Conclusion Cancer professionals should identify the influencing factors of falls early and take targeted measures to reduce the occurrence of falls.

Objective To explore the current status of oncology nurses'medical narrative competence and to analyze its influencing factors.Methods 931 nurses from the oncological departments of 17 3A grade hospitals in Yunnan Province were selected from June to August 2023 and were surveyed using the Medical Narrative Competence Scale,the General Self-Efficacy Scale,and the Humanistic Care Scale.Results The score of medical narrative competence of oncology nurses was(151.52±14.61).The results of multiple linear regression showed that general self-efficacy,humanistic competence,years of experience,department,peer support,family support,familiarity with medical narratives,and job satisfaction were the factors influencing oncology nurses'competence in medical narratives(P<0.05),which explained 38.0%of the total variation.Conclusion The medical narrative competence of oncology nurses,moderately level,is influenced by multiple factors.

Objective To explore the different latent class and characteristics of the cognitive ability level of undergraduate nursing students in hospice care based on the individual-centered perspective,and analyze its influencing factors to provide the reference for the formulation of targeted nursing education.Methods Nursing students in a medical university in Yunnan Province were selected from March 2023 to June 2023.The general data questionnaire and hospice care knowledge questionnaire were used to conduct a cross-sectional survey.SPSS and Mplus were used for the data analysis.Results Three latent class of hospice care cognitive ability were identified,which were named as hospice care high cognitive ability group,general cognitive ability group,and low cognitive ability group,accounting for 28.74%,57.29%,and 13.97%,respectively;Nursing students'gender,nationality,place of residence,earning and practice experience of hospice care(whether they had the contact with end-stage cancer patients,whether they had received the hospice care related training),and whether they were willing to engage in the hospice care related work were the influencing factors of different potential categories of cognitive ability of hospice care among nursing students(P<0.05).Conclusion There are three latent class of hospice care cognitive ability of nursing students.Male minority nursing students who have not been exposed to end-stage cancer patients and have not received the hospice care-related training,are unwilling to engage in the hospice care-related work.Male ethnic minority nursing students residing in rural areas have the weaker cognitive levels of hospice care.Scholars in the future can formulate targeted training strategies according to different latent class of hospice care cognitive ability to improve nursing students'hospice care cognitive ability and reserve talents for hospice care teams.

Objective To investigate the research status and the research hotspots on male nurses at home and abroad in last decade,so as to provide references for further research in male nurses.Methods Literature between 2013 and 2024 on male nurses were retrieved from the Web of Science(WOS)and CNKI.CiteSpace 6.2.6 R7 software was used to analyse the volume of publication,keyword co-occurrence,keyword clustering and emergence.Results A total of 736 articles were included in the study.From 2013 to 2023,the number of published papers of male nurses in CNKI and WOS showed an increasing trend.The research was primarily affiliated with 263 institutions across 62 countries.The country with the highest volume of publication is China,followed by the United States,although there was a need to enhance collaboration with other nations.The institution with the most publications is the Hong Kong Polytechnic University.A comprehensive analysis of keyword co-occurrence,clustering,and emerging trends revealed that the research hotspots in the field of male nursing in CNKI mainly includes the advantages of male nurses,psychological capital,humanistic care,development,needs,professional identification.Whereas WOS focuses on the topics such as gender bias against male nurses,mental health,workplace violence,ambivalent sexism,motivational barriers,individual differences,societal prejudice and knowledge and attitucle.Both domestic and international research on male nurses primarily consist of cross-sectional surveys and qualitative studies,with fewer intervention studies.Currently,the researches regarding male nursing focus on the qualitative study of mental health of male nurses.Conclusion Focusing on the mental health and professional status of male nurses,domestic scholars need to increase the formulation and implementation of interventions in this field in order to address the practical issues faced by male nurses,therefore to promote the comprehensive development of the nursing profession,enhance the overall quality and service quality of the nursing team,and provide patients with higher quality in nursing services.

Objective:To investigate the status of hepatitis E virus infection in unpaid blood donors in Wenzhou.Methods:A total of 5 241 blood samples were selected from donors who successfully donated blood between October 2022 and March 2023. These samples were tested for hepatitis E virus (HEV) through HEV-IgG antibodies, HEV-IgM antibodies, and nucleic acid tests (HEV RNA). Samples that tested positive for HEV RNA underwent quantitative detection and sequencing. Data regarding the blood donors were collected, the positive rates of each test result were recorded, and the HEV infection status among different populations was analyzed.Results:The positive rate of the HEV-IgG antibody test was 23.60% (1 237/5 241), while the positive rate of the HEV-IgM antibody test was 0.29% (15/5 241). The positive rate of the HEV RNA test was 0.08% (4/5 241). The positive rate of the HEV-IgG test increased with age ( χ2 = 379.493, P < 0.05), and males had a higher positive rate than females ( χ2 = 5.12, P < 0.05). Both the positive rates of HEV-IgG and HEV-IgM tests increased as the number of blood donations increased ( χ2 = 40.87, 8.30, both P < 0.05). Furthermore, the positive rates were significantly higher in 2023 than in 2022 ( χ2 = 51.03, 13.35, both P < 0.05), and they were also significantly higher in spring than in winter ( χ2 = 51.03, 13.35, both P < 0.05). Only one HEV RNA-positive blood donor tested positive for both HEV-IgG and HEV-IgM antibodies, while the remaining three donors tested negative. Only one case was genotyped, and it belonged to genotype Ⅳ. Conclusion:The incidence of HEV infection among unpaid blood donors in Wenzhou of Zhejiang Province is relatively high, with the prevalent HEV genotype being type Ⅳ. Characteristics such as sex, age, and the number of blood donations can be utilized as auxiliary screening reference indicators.

BACKGROUND: The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis. METHODS: In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis. RESULTS: A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP. CONCLUSIONS Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

ObjectiveTo explore the mechanism of Buyang Huanwutang in regulating macrophage polarization based on the Toll-like receptor 4 （TLR4） / nuclear factor-κB （NF-κB） / nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） pathway. MethodRAW264.7 macrophages were intervened with lipopolysaccharide （LPS） of different concentrations （0， 1.25， 2.5， 5， 10， 20， 40， and 80 mg·L^-1） for 24 hours. Cell Counting Kit-8 （CCK-8） assay was used to determine the cell viability of RAW264.7 macrophages. The optimal concentration was chosen to establish an in vitro inflammation model induced by LPS. Cells were divided into a blank group （20% blank serum）， a model group （20% blank serum + 10 mg·L^-1 LPS）， a model control group （20% FBS + 10 mg·L^-1 LPS）， low-， medium-， and high-dose （5%， 10%， and 20%） Buyang Huanwutang-containing serum groups， a high-dose （20%） Buyang Huanwutang combined with NLRP3 inhibitor MCC950 （50 μmol·L^-1） group， a high-dose （20%） Buyang Huanwutang combined with reactive oxygen species （ROS） inhibitor NAC （10 μmol·L^-1） group， and a high-dose （20%） Buyang Huanwutang combined with NF-κB inhibitor PDTC （10 μmol·L^-1） group. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression of interleukin-1β （IL-1β）， interleukin-18 （IL-18）， and tumor necrosis factor-α （TNF-α） in RAW264.7 macrophages. Flow cytometry was employed to measure ROS levels in macrophages. Western blot was used to determine the protein expression of M1-type macrophage-related factors inducible nitric oxide synthase （iNOS） and TNF-α， M2-type macrophage-related factors arginase-1 （Arg-1） and interleukin-10 （IL-10）， as well as the proteins in the TLR4/NF-κB/NLRP3 pathway. ResultCCK-8 results indicated that under 10 mg·L^-1 LPS stimulation， RAW264.7 macrophages exhibited the highest cell viability （P<0.01）. Compared with the blank group， the model group showed significantly increased levels of IL-1β， IL-18， and TNF-α （P<0.05，P<0.01）， increased ROS expression （P<0.05，P<0.01）， increased protein expression of M1-type macrophage factors iNOS and TNF-α （P<0.01）， decreased protein expression of M2-type macrophage factors Arg-1 and IL-10 （P<0.05，P<0.01）， and upregulated expression levels of TLR4， myeloid differentiation factor 88 （MyD88）， phosphorylated inhibitor of NF-κB （p-IκB）/NF-κB inhibitor （IκB）， phosphorylated NF-κB （p-NF-κB） p65/NF-κB p65， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， and pro-Caspase-1 （P<0.05， P<0.01）. Compared with the model group， all Buyang Huanwutang-treated groups and inhibitor groups significantly reduced levels of IL-1β， IL-18， and TNF-α （P<0.01）， suppressed the expression of inflammatory factors in RAW264.7 macrophages， decreased cellular ROS expression levels （P<0.01）， downregulated M1-type macrophages iNOS and TNF-α protein expression （P<0.01）， upregulated M2-type macrophages Arg-1 and IL-10 protein expression （P<0.01）， and lowered protein expression levels of TLR4， MyD88， p-IκB/IκB， p-NF-κB p65/NF-κB p65， NLRP3， ASC， and pro-Caspase-1 （P<0.05， P<0.01）. ConclusionBuyang Huanwutang can improve macrophage inflammation， potentially by reducing macrophage ROS levels， inhibiting RAW264.7 macrophage polarization， and downregulating the protein expression levels of the TLR4/NF-κB/NLRP3 pathway.
