Objective To describe the spatiotemporal distribution characteristics of Severe Fever with Thrombocytopenia Syndrome (SFTS) in Zibo City and identify its environmental influencing factors and potential high-risk areas, and to propose targeted strategies for SFTS prevention and control. Methods Data on SFTS incidence from 2010 to 2024 were collected. Spatiotemporal scan statistics were used to identify the time and area of SFTS clustering. The maximum entropy (MaxEnt) model was used to analyze environmental influencing factors and predict high-risk areas. Results From 2010 to 2024, a total of 459 cases of SFTS were reported in Zibo. The number of SFTS cases increased yearly, with a peak incidence from April to October each year. Spatiotemporal scan statistics showed the existence of one class I cluster and one class II cluster areas in Zibo. The class I cluster was in Yiyuan District and southern Boshan District, from April to September 2024. The class II cluster was in the center of Zichuan District, from July to September 2024. The MaxEnt model showed that yearly average atmospheric pressure (PRS), yearly average evaporation (EVP), yearly average sunshine duration (SSD) and goat density (Goat) were the key factors influencing the occurrence of SFTS. The predicted risk map showed that the area of high prevalence was 1116 km2, accounting for 18.71% of the total area of the city. Conclusion The spatiotemporal distribution of SFTS exhibits heterogeneity and is influenced by multidimensional environmental factors. This should be considered as a basis for delineating SFTS risk areas and developing SFTS prevention and control measures.

ObjectiveTo evaluate the clinical effects of Yishen Tongluo Prescription in treating patients with idiopathic asthenozoospermia and teratozoospermia due to kidney deficiency and collateral obstruction， as well as the effects of this formula on biochemical indices and oxidative stress of seminal plasma. MethodsPatients who fulfilled the inclusion criteria were randomly allocated by the random number table method into an observation group （61 patients， including 2 dropped out and 59 completed） and a control group （61 patients， including 2 dropped out， 1 excluded， and 58 completed）. The observation group took Yishen Tongluo Prescription orally， 1 dose/day， and the control group took levocarnitine oral solution， 10 mL/time， 3 times/day. Both groups received a treatment course of 12 weeks and were followed up for 6 weeks. The percentage of progressive motile sperms （PR）， percentage of sperms with normal morphology， seminal plasma oxidative stress indicators ［malondialdehyde （MDA） and superoxide dismutase （SOD）］， seminal plasma biochemical indicators ［acid phosphatase （ACP）， zinc （Zn）， fructose （Fru）， and alpha-glucosidase （α-Glu）］， and traditional Chinese medicine （TCM） symptom scores were recorded for both groups before and after treatment. ResultsThe total response rate in the observation group was 76.3% （45/59）， which was higher than that （44.8%， 26/58） in the control group （χ²=12.120， P<0.05）. After treatment， both groups of patients showed increases in PR， percentage of sperms with normal morphology， and seminal plasma SOD level （P<0.05）， which were higher in the observation group than in the control group （P<0.05）. The MDA level and TCM symptom scores decreased in both groups after treatment （P<0.05）， and the decreases were more obvious in the observation group than in the control group （P<0.05）. After treatment， the seminal plasma levels of ACP， Zn， Fru， and α-Glu in the observation group （P<0.05） and that of α-Glu in the control group （P<0.05） rose. Moreover， the observation group had higher seminal plasma levels of ACP， Zn， Fru， and α-Glu than the control group （P<0.05）. Neither group showed obvious adverse reactions. ConclusionIn summaryYishen Tongluo prescription is able to improve the sperm vitality and reduce the sperm abnormality rate in infertile patients with idiopathic asthenozoospermia and teratozoospermia due to kidney deficiency and collateral obstruction. It may exert therapeutic effects by regulating the microenvironments of the epididymis， prostate， and seminal vesicles， thereby recovering the seminal plasma biochemical levels， enhancing the antioxidant capacity of seminal plasma， clearing excessive reactive oxygen species， and alleviating oxidative stress.

Cuproptosis, a recently discovered form of regulated cell death involving copper ion metabolism, has emerged as a promising approach for tumor therapy. This pathway not only directly eliminates tumor cells but also promotes immunogenic cell death (ICD), reshaping the tumor microenvironment (TME) and initiating robust anti-tumor immune responses. However, translating cuproptosis-based therapies into clinical applications is hindered by challenges, including complex metabolic regulation, TME heterogeneity, and the precision required for effective drug delivery. To address these limitations, nanoparticles offer transformative solutions by providing precise delivery of cuproptosis-inducing agents, controlled drug release, and enhanced therapeutic efficacy through simultaneous modulation of metabolic pathways and immune responses. This review systematically discusses recent advancements in nanoparticle-based cuproptosis delivery systems, highlighting nanoparticle design principles and their synergistic effects when integrated with other therapeutic modalities such as ICB, PTT, and CDT. Furthermore, we explore the potential of cuproptosis-based nanomedicine for personalized cancer treatment by emphasizing strategies for TME stratification and therapeutic optimization tailored to patient profiles. By integrating current insights from metabolic reprogramming, tumor immunotherapy, and nanotechnology, this review aims to facilitate the clinical translation of cuproptosis nanomedicine and significantly contribute to the advancement of precision oncology.

Objective To summarize the experience of integrative palliative care at Peking Union Medi-cal College Hospital and provide a reference for promoting the integrative palliative care model.Methods Twenty cases receiving integrative palliative care at Peking Union Medical College Hospital were collected.The clinical characteristics,reasons for initiating integrative palliative care,the process of integrative palliative care,and feedback from these cases were summarized.Results Insomnia(11 cases,55％)and pain(9 cases,45％)were the most common symptoms requiring control in the 20 cases.The integrative palliative care team assisted in medical decision-making for 17 cases(85％),prepared end-of-life for 9 cases(45％),assisted in the transfer for 3 cases(15％),and provided comfort care for all the 20 cases(100％).Conclusions The integrative palliative care model can help alleviate suffering in end-of-life patients and provide support to patients'families and the original medical teams.This model is worth further promotion within class A tertiary hospitals.

Objective To explore the mechanism of human umbilical cord mesenchymal stem cell (HUC-MSC) alleviating ischemia-reperfusion injury (IRI) of liver cells through mitochondrial transfer. Methods Normal human liver cell line L02 was divided into the blank control group, oxygen-glucose deprivation (OGD) group, experimental control group, and L02 and HUC-MSC co-culture group (L02+HUC-MSC group). L02+HUC-MSC group was further divided into 10:1 co-culture subgroup (group A), 4:1 co-culture subgroup (group B), 2:1 co-culture subgroup (group C), 1:1co-culture subgroup (group D) and 1:2 co-culture subgroup (group E) according to different co-culture ratio of L02 and HUC-MSC. The apoptosis rate and relative reactive oxygen species (ROS) level of L02 cells were detected by flow cytometry. The MitoTracker positive rate of L02 cells was detected by flow cytometry. The mitochondrial transfer from HUC-MSC to L02 cells was observed by laser confocal microscope. Results The apoptosis rate and relative ROS level of L02 cells in the OGD group were significantly higher than those in the blank control group (both P < 0.05). Compared with the OGD group, the apoptosis rates of L02 cells in group B, C, D and E were significantly decreased (all P < 0.05), and the relative ROS level of L02 cells in group E was significantly declined (P < 0.05). The MitoTracker positive rate of L02 cells did not significantly differ between group A and experimental control group (P>0.05), whereas the MitoTracker positive rates of L02 cells in group B, C, D and E were significantly higher than that in the experimental control group in a concentration-dependent manner (all P < 0.05). Under the laser confocal microscope, mitochondrial transfer fromHUC-MSC to L02 cells could be observed through tunneling nanotube (TNT). Conclusions HUC-MSC may alleviate cell apoptosis and reduce ROS level of liver cells after IRI via direct mitochondrial transfer between cells.
