Immunotherapy has become a pivotal modality in clinical cancer treatment. However, its effectiveness is limited to a small subset of patients due to the low antigenicity, impaired innate response, and various adaptive immune resistance mechanisms of the tumor microenvironment (TME). Accumulating evidence reveals the critical roles of metal elements in shaping immunity against tumor progression and metastasis. The marriage of metalloimmunotherapy and nanotechnology further presents new opportunities to optimize the physicochemical and pharmacokinetic properties of metal ions in a precise spatiotemporal control manner. Several metallodrugs have demonstrated encouraging immunotherapeutic potential in preliminary studies and are currently undergoing clinical trials at different stages, yet challenges persist in scaling up production and addressing long-term biosafety concerns. This review delineates how metal materials modulate biological activities across diverse cell types to orchestrate antitumor immunity. Moreover, it summarizes recent progress in smart drug delivery-release systems integrating metal elements, either as cargo or vehicles, to enhance antitumor immune responses. Finally, the review introduces current clinical applications of nanomedicines in metalloimmunotherapy and discusses potential challenges that impede its widespread translation into clinical practice.

Objective:To establish a menstrual prediction model after the first course of hormone replacement therapy(HRT)in premature ovarian insufficiency(POI)patients after allogeneic hematopoietic stem cell transplan-tation(allo-HSCT),and to provide certain reference value for formulating HRT plans.Methods:The retrospective analysis recruited 154 POI patients after allo-HSCT in the First Affiliated Hospital of Soochow University from Jan-uary 2017 to October 2022.They were divided into ideal menstruation group(n=116)and unideal menstruation group(n=38)according to menstruation after the first course of HRT.Basic characteristics and clinical data were compared in single-factor analysis to select predictive factors.Patients were randomly divided into training set and test set.The menstrual prediction model was developed based on random forest algorithm on the training set and the prediction efficiency was verified by the test set.Finally,we made a user interaction interface and deployed to the server for sharing.Results:The single-factor analysis suggested statistic difference of age of visit,body mass index(BMI),gravidity,parity,hematologic diseases,transplantation age,donor gender,follicle-stimulating hormone(FSH),Luteinizing Hormone(LH),lumbar bone mineral density(BMD)and HRT plan(P<0.05).According to mean decrease accuracy,the predictive factors included visit age,transplantation age,BMI,FSH,HRT plans,gravidity and parity.After the initial establishment of the random forest model,we improved it by adjusting ntree to 500,mtry to 6 and training/test set division to 80%/20% .We also used tenfold cross validation to reduce over-fitting.The area under curve(AUC)of the final constructed menstrual prediction model was 0.768,a sensitiv-ity of 0.695 and a specificity of 0.735.Conclusions:This study successfully established a menstrual prediction model for amenorrhea patients after allo-HSCT when finished the first course of HRT.The false positive rate was low,suggesting that if the prediction result of the model is non-ideal menstruation,we may consider adjusting HRT plans to promote menstruation in time.

【Objective:】 To understand the current status of narrative nursing knowledge, attitude, and practice (KAP) among nurses in grade A tertiary hospitals, and to provide a basis for the development of narrative nursing in relevant areas. 【Methods:】 Using convenience sampling methods, 931 nurses from three grade A tertiary hospitals in Xi’an were selected as subjects. A cross-sectional survey was conducted using the Clinical Nurses’ Narrative Nursing Knowledge and Trustworthiness Questionnaire and the General Self-Efficacy Scale. Multiple linear regression analysis was used to explore the influencing factors of nurses’ narrative nursing KAP. 【Results:】 The scores on the three dimensions of narrative nursing KAP were (23.70±2.99) points, (31.69±5.92) points, and (30.26±5.32) points, respectively. Nursing workload, general self-efficacy, professional title, and nursing satisfaction were the influencing factors of nurses’ narrative nursing knowledge dimension (P<0.05). There were statistically significant differences in nurses’ narrative nursing attitude dimension among nursing workload, general self-efficacy, professional title, monthly income, and nursing satisfaction (P<0.05). Nursing workload, general self-efficacy, nursing satisfaction, and accompanying experience were the influencing factors of nurses’ narrative nursing behavior dimension (P<0.05). 【Conclusion:】 Nurses in grade A tertiary hospitals have moderate narrative nursing knowledge, positive attitudes, and poor practice execution. The high nursing workload is the main barrier factor for the current development of narrative nursing. Nursing managers should actively build a diversified training system and guarantee system to boost the development of narrative nursing in clinical nursing work, and further promote the development of narrative nursing concepts.
