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 discuss their effects of PLA(polylactic acid)/PTMC(polytrimethylene carbonate)and PLA/PTMC-calcium phosphate[Ca3(PO4)2]composite porous scaffolds prepared by 3D printing technology on bone marrow mesenchymal stem cells(BMSCs)of the rabbits,and to clarify their application values in bone defect repairment.Methods:After mixing the materials,PLA/PTMC and PLA/PTMC-Ca3(PO4)2 filaments were prepared by desktop filament extruder.The scaffolds were designed by CATIA V5-6R2019 modeling software and fabricated using CreatBot F430 3D printer.The chemical structure of the PLA/PTMC-Ca3(PO4)2 scaffold was detected by infrared spectroscopy.In vitro degradation experiments were used to detect the degradation weight loss rates and pH values of the two scaffolds.A contact angle measuring instrument was used to detect the hydrophilicities of the two scaffolds.The BMSCs were extracted from three newborn New Zealand white rabbits(2-5-day-old);CCK-8 method was used to detect the proliferation activities of the cells co-cultured with two scaffolds,and Alizarin red staining was used to observe the osteogenic differentiation of the cells co-cultured with two scaffolds.Results:Infrared spectroscopy confirmed the successful preparation of composite scaffolds containing PLA,PTMC,and β-Ca3(PO4)2.During degradation for 6-14 weeks,compared with PLA/PTMC scaffold,the degradation rates of the PLA/PTMC-Ca3(PO4)2 scaffold in lipase solution and phosphate-buffered saline(PBS)were significantly increased(P<0.05 or P<0.01).During degradation for 8-14 weeks,compared with PLA/PTMC scaffold,the pH value of the PLA/PTMC-Ca3(PO4)2scaffold in lipase solution was significantly increased(P<0.01).Compared with PLA/PTMC scaffold,the contact angle of the PLA/PTMC-Ca3(PO4)2 scaffold was significantly decreased(P<0.01).On days 5 and 7 of cell co-culture,compared with PLA/PTMC scaffold,the proliferation activity of the cells co-cultured with PLA/PTMC-Ca3(PO4)2 scaffold was significantly increased(P<0.05 or P<0.01).After 21 d of co-culture,both scaffolds overlapped with BMSCs and locally formed calcified nodules,which were stained orange by Alizarin red.Compared with PLA/PTMC scaffold,the number of mineralized calcium nodules in the cells co-cultured with PLA/PTMC-Ca3(PO4)2 scaffold was increased,with greater density and deeper color.Conclusion:The PLA/PTMC-Ca3(PO4)2 composite porous scaffolds containing PLA,PTMC,and β-Ca3(PO4)2 are successfully prepared by 3D printing technology.These scaffolds exhibit good degradation properties and show advantages in biocompatibility,hydrophilicity,and osteogenic induction;they are excellent materials for the bone defect repairment.

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 explore surgical procedure of combined anterior-lateral and lateral approach for the treatment of bone tumors of femoral neck. Methods Forty patients with bone tumors of femoral neck treated in Tianjin Hospital were included from July 2005 to August 2009. Of the patients, 12 who were treated with curettage and bone graft through combined anterior-lateral and lateral incision were analyzed in this study. There were 7 males and 5 females with an average age of 34 years ranging from 17 to 68 years. 4 patients were diagnosed as chondroblastoma, 2 giant cell tumor, 3 fibrous dysplasia, and 3 single bone cysts. 7 patients suffered from pathologic fractures, and 5 had presented thin cortical bone because of tumor involvement. There were 1 tumor located in H1 zone, 4 in H2 zone and 7 in H1,2 zone according to ISOLS femoral neck classification. All patients were treated by curettage and bone graft via anterior-lateral approach, 10 cases underwent internal fixation with anatomical plate, and 2 cases with canulated screws with lateral approach. Results The follow-up time ranged from 10 to 68 months with an average of 35 months.Pain disappeared in all patients, and there were not recurrence of tumor, pathologic fractures and avascular necrosis. One case had complained of lateral femoral skin numbness which may be caused by injures of femoral lateral nerves. One case had difficulties in the valgus of hip joint. The mean MSTS score was 29.2 points ranging from 27 to 30 points. Conclusion Anterior approaches of "SP" incision is helpful to thorough curettage which decrease the risk of recurrence due to good visualization and intemal fixation is easy to perform via lateral approaches. The result suggested that combined anterior-lateral "SP" and lateral incision is liable option in treatment of bone tumors of femoral neck.
