Existentialist philosophy focuses on human existence， explores subjectivity and uniqueness， and highlights the value of human existence. Advanced cancer patients generally suffer immense existential distress， each with their own modes of appearance and numerous possibilities. From the perspective of existentialist philosophy， targeting the group of advanced cancer patients， this paper clarified the analysis of “Dasein” （holistic phenomenon and modes of appearance）. Through recognition （achieving to deepen the inner scope of the subject and object） and comprehension （seeking appropriate “self-knowledge”）， it introduced the planning of variable possibilities. Subsequently， based on the patients’ pre-possessing， pre-seeing， and pre-grasping， explanatory activities were carried out to complete the “self-formation” in the planning. Ultimately， it facilitated the realization of existential meaning in the presupposition and proposed actionable clinical practices （meaning therapy and emotional touch therapy） to alleviate the existential distress of advanced cancer patients.

Objective To analyze the influenza-like illness (ILI) data in Ordos City from 2017 to 2023 and conduct nucleic acid detection of the virus to understand the local influenza epidemic situation, and to provide a reliable basis for influenza prevention and control in the city. Methods Real-time quantitative polymerase chain reaction (qPCR) was used to identify virus subtypes in ILI throat swab samples. Comparisons of positive rates were conducted using the chi-square test, with a significance level of α=0.05. Results From 2017 to 2023, a total of 3,283,434 outpatient and emergency visits were recorded at the Ordos City Central Hospital, including 74,159 ILI cases, with an ILI proportion of 2.26%. The majority of ILI cases (74.43%) occurred in children aged 0~14 years old. The overall positive rate of influenza virus nucleic acid detection was 10.87%, with the highest proportion being subtype A (seasonal H3) at 43.03%. The highest detection rate was observed in the 5~14 years age group, with statistically significant differences in positive rates across age groups (χ²=155.638, P<0.001). Influenza peaks occurred mainly from November to March of the following year. From January to April, three types of influenza were prevalent alternately or mixed, while from October to December, subtype A (seasonal H3) predominated. Positive rates varied significantly across months (χ²=250.923, P<0.001). The temporal trends of ILI proportions and PCR-positive rates were consistent. Conclusion Influenza in Ordos City exhibits distinct seasonal and age distribution characteristics, with alternating or mixed circulation of three virus types. Continued efforts are needed to strengthen influenza surveillance, especially the prevention and control of influenza in infants and adolescents.

As a pivotal strategy to alleviate the shortage of organ donors, xenotransplantation has achieved remarkable advances in both pre-clinical and clinical studies in recent years, driven by continuous optimization of gene modification techniques and immunosuppressive regimens. Nevertheless, clinical translation still confronts formidable challenges, including rejection and heightened infection risks, which severely compromise long-term graft survival. Consequently, the role of immunosuppressive regimens in xenotransplantation has become increasingly prominent. This article summarizes the mechanisms underlying xenogeneic immune rejection, the latest developments in immunosuppressive regimens, cutting-edge strategies for inducing immune tolerance and the major hurdles facing clinical xenotransplantation. It delves into potential optimization strategies and directions for future clinical research, aiming to offer theoretical insights and practical guidance for the safe and effective application of clinical xenotransplantation.

Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

Objective To analyze the clinical efficacy of intelligent wireless endoscopy in transurethral resection of the prostate, so as to provide evidence for clinical application. Methods A retrospective analysis was conducted on the clinical data of 70 patients with benign prostatic hyperplasia (BPH) who underwent transurethral resection of the prostate at Tongling People's Hospital during Jan. 2023 and Dec. 2024. Based on the type of endoscopes used, patients were divided into a wireless endoscopy group and a traditional endoscopy group, with 35 patients in either group. Differences between the two groups were compared in terms of surgical preparation time, operation time, postoperative hospital stay, catheter indwelling time, intraoperative blood loss, surgical complications, and operating comfort during the procedure. Results All 70 operations were successfully completed without severe urinary incontinence. The wireless laparoscopy group demonstrated significantly shorter surgical preparation time compared to the traditional laparoscopy group [(12.14±2.39)min vs. (14.89±0.80)min, P＜0.001].There was no statistically significant difference in the operation time between the two groups [(93.51±34.49)min vs. (101.71±34.87)min, P=0.326]. There were no statistically significant differences between the two groups in postoperative hospital stay, catheter indwelling time, intraoperative blood loss, and surgical complications (P＞0.05). The wireless endoscopy group demonstrated significantly higher operating comfort compared to the traditional endoscopy group [(3.94±0.77) vs. (2.57±0.61), P＜0.001]. Conclusion The use of intelligent wireless endoscopy for transurethral resection of the prostate is comparable to traditional endoscopy in surgical efficacy and patient safety, but it can shorten preoperative preparation time and improve operator comfort.

Organ transplantation faces the challenge of a shortage of donors. Although xenotransplantation holds great potential, it is limited by rejection. Extracellular histones, as key members of damage-associated molecular patterns, have been proven in recent years to play a crucial role in transplant rejection by activating innate immunity, regulating the coagulation-inflammation network, and modulating adaptive immune responses. However, the specific functions and key mechanisms remain to be clarified. Therefore, this article reviews the structural characteristics of histones, their release pathways, the biological functions of extracellular histones, and their potential roles in xenotransplantation. It summarizes the latest research progress of extracellular histones in xenotransplantation, analyzes the shortcomings of existing research and the direction for future research, with the expectation of providing references for the application of extracellular histones in xenogeneic kidney transplantation.

Objective:To explore the effect of Swanson theory combined with hand touch on the existential distress of patients with advanced lung cancer, in order to provide reference for clinical humanistic care.Methods:A non synchronous controlled study was conducted using convenience sampling to select advanced lung cancer patients admitted to the Oncology Department of the First People's Hospital of Yongkang City, Zhejiang Province from October 2023 to March 2024 as the control group, and advanced lung cancer patients admitted from April to October 2024 as the experimental group. The control group received routine care, while the experimental group received Swanson theory combined with hand touch intervention on the basis of routine care. The Existential Distress Scale (EDS) and Functional Assessment of Cancer Therapy- General (FACT-G) scores of the two groups were compared before and 2 weeks after intervention.Results:During the study period, there were 3 dropouts in the experimental group and 2 dropouts in the control group. Finally, 37 cases were included in the experimental group, including 16 males and 21 females, with an age of (62.35 ± 12.13) years. There were 38 cases in the control group, including 25 males and 13 females, with an age of (65.68 ± 13.46) years. After 2 weeks of intervention, the EDS score of the experimental group patients was (6.65 ± 2.89) points, while that of the control group was (8.16 ± 2.27) points. The difference between the two groups was statistically significant ( t = 2.52, P<0.05). After intervention, the social/family status dimension, emotional status dimension, and total score of FACT-G in the experimental group were (15.35 ± 4.18), (19.27 ± 3.54), and (57.46 ± 14.69) points, respectively, which were better than the control group's (13.08 ± 3.77), (16.53 ± 3.88), and (50.58 ± 11.86) points. The difference between the two groups was statistically significant ( t = - 2.47, - 3.20, - 2.24, all P<0.05). Conclusions:The combination of Swanson theory and hand touch can effectively reduce the existential distress of patients with advanced lung cancer, improve their quality of life, and embody the concept of nursing humanistic care into simple and safe intervention measures, providing reference for clinical humanistic care.
