Objective To explore the mediating effect of hope between self-perceived burden and quality of life in patients with recurrent malignant tumors.Methods A cross-sectional survey was conducted using convenience sampling,selecting 204 patients with recurrent malignant tumors from the Oncology Department of Xiangyang Central Hospital in Hubei Province from September to December 2023.A general information questionnaire,Self-Perceived Burden Scale(SPBS),hope level(HHI),and EORTC QLQ-C30 quality of life questionnaire were utilized for the investigation.Results The SPBS score for patients with recurrent malignant tumors was(28.28±8.92),the HHI score was(35.83±4.30)and the quality of life score was(59.68±23.96).Self-perceived burden was negatively correlated with hope and quality of life(P<0.05;P<0.01),while hope was positively correlated with quality of life(P<0.01).The mediating effect of hope between the burden of self-perception and quality of life is reflected,with the indirect effect accounting for 21.18%of the total effect.Conclusion Patients with recurrent malignant tumors generally have a low quality of life and moderate levels of hope,both of which require improvement.The self-perceived burden of patients is at a mild to moderate level.Healthcare professionals should take effective measures to enhance patients'levels of hope and reduce their self-perceived burden,thereby improving the quality of life for patients with recurrent malignant tumors.

Objective:To systematically integrate the disease experience of patients with systemic lupus erythematosus, and to provide evidence-based evidence for the formulation of health management programs based on the psychological experience of patients with systemic lupus erythematosus.Methods:Qualitative studies on psychological experience of patients with systemic lupus erythematosus were searched by computer in PubMed, Cochrane Library, CINAHL, Embase, Web of Science, ProQuest, CNKI, Wanfang Database, VIP and China Biology Medicine disc. The search period was from the establishment of the databases to July 2023. The quality of literature was evaluated using the Quality Evaluation Criteria (2020) of Evidence-Based Health Care Center of Joanna Briggs Institute, Australia, and the results of literature studies were integrated by Meta integration method.Results:A total of 13 articles were included, 48 research results were extracted and eight categories were summarized, ultimately forming three integrated results including "negative psychological experience", "increased disease demand" and "active regulation strategies".Conclusions:Medical staff should pay attention to the physical and mental feelings of patients with systemic lupus erythematosus during the disease process and provide targeted and effective intervention strategies in clinical practice to alleviate their negative emotions and improve their quality of life.

In recent years, there has been an increasing emphasis on exploring innovative drug delivery approaches due to the limitations of conventional therapeutic strategies, such as inadequate drug targeting, insufficient therapeutic efficacy, and significant adverse effects. Nanomedicines have emerged as a promising solution with notable advantages, including extended drug circulation, targeted delivery, and improved bioavailability, potentially enhancing the clinical treatment of various diseases. Natural products/materials-derived nanomedicines, characterized by their natural therapeutic efficacy, superior biocompatibility, and safety profile, play a crucial role in nanomedicine-based treatments. This review provides a comprehensive overview of currently approved natural products-derived nanomedicines, emphasizing the essential properties of natural products-derived drug carriers, their applications in clinical diagnosis and treatment, and the current therapeutic potential and challenges. The aim is to offer guidance for the application and further development of these innovative therapeutic approaches.

objective To investigate the value of NT-proBNP in assessing the volume status in maintenance hemodialysis patients with non-dominant edema.Methods One hundred and forty-five patients were recruited.Bioimpedance measurements were performed for overhydration (OH).NT-proBNP was detected by colloidal gold method.Patients were divided into three groups by levels of OH variability (△ OH,equal to OH minus weight increase) as group H (hypervolemia,n=90); group N (normovolemia,n=36) and group L (hypovolemia,n=19).Hemoglobin,albumin,blood urea nitrogen and serum creatinine were assayed,blood pressure and body mass increase were recorded.Dry weight of patients in Group H were adjusted in 3 months,the relationship between NT-proBNP and volume change were assessed.Results (1) At baseline,overall plasma NT-proBNP levels were higher than normal range.The median NT-proBNP levels in group H and group N were [1318.50(IQR 717.00,3154.25) pg/ml] and [703.50 (IQR 873.00,450.50) pg/ml],respectively.NT-proBNP was positively correlated with △OH value (r=0.801,P ＜ 0.001).(2) After 3 months,NT-proBNP levels in group H was significantly lower than baseline.Forty-one patients reached normal volume range (group H1),49 patients were resistant hypervolemia (group H2).The median NT-proBNP levels in group H1 and group H2 were [685.00 (IQR 422.50,988.50) pg/ml] and [1569.00 (IQR 982.50,2500.50) pg/ml],△ OH in group H1 and group H2 were [(0.63±0.23)L] and [(1.75±0.71)L],respectively.NT-proBNP and △ OH value in two groups had significant difference (P ＜ 0.05).NT-proBNP was positively correlated with △ OH value (r=0.684,P ＜ 0.001).(3) The area under ROC curve for NT-proBNP was 0.818,95％CI (0.733～ 0.904),P ＜ 0.001,since the absolute value of normovolemia was defined as ≤ 1.The cut off value of plasma NT-proBNP was set at 962.50 pg/ml in MHD patients with non-dominant edema,the diagnostic specificity and sensitivity were 79.6％ and 73.2％.Conclusion NT-proBNP could be used to assess volume status in MHD patients with non dominant edema.

This study discussed the dual affiliated institutions of one author in a scientific paper.This issue could give rise to troubles such as the dispute over signature rights, dispute over intellectual property rights, etc. Moreover, it could bring negative effects on the development of science. In addition, some suggestions were put forward to deal with this issue.
