Background With the continuous development of the healthcare industry, healthcare workers face increasing pressure, including long-term shift work and workplace violence from patients or their relatives. This not only affects the physical and mental health of healthcare workers but may also negatively impact the quality of patient care and the efficiency of medical services. Objectives To analyze the pathways through which shift work and workplace violence affect healthcare workers' self-rated health and depression symptoms, explore potential mediating role of job burnout, and conduct subgroup analyses to reveal differences among various groups. Methods Data were collected from 3706 frontline healthcare workers across 23 provinces from January 10 to February 5, 2019, using a snowball sampling method. The survey included basic demographic information, self-rated health, depression symptoms [assessed using the Patient Health Questionnaire-2 (PHQ-2)], workplace violence experience assessed using the Workplace Violence Scale), and job burnout (assessed using the Chinese Maslach Burnout Inventory). Data were analyzed using logistic regression, structural equation modeling (for mediating effects), and subgroup analysis to examine the impacts of shift work and workplace violence on health and depression symptoms. Results Among the subjects, 2700 workers (73.29%) reported shift work experience, 2079 workers (56.43%) experienced workplace violence, 633 workers (17.18%) reported poor self-rated health, and 687 workers (18.65%) reported depression symptoms. Shift work was associated with self-rated health (OR=0.572, 95%CI: 0.461, 0.710) and depression symptoms (OR=1.519, 95%CI: 1.190, 1.938), while workplace violence also associated with self-rated health (OR=0.566, 95%CI: 0.471, 0.681) and depression symptoms (OR=2.096, 95%CI: 1.740, 2.525). Job burnout significantly mediated the effects of shift work and workplace violence on self-rated health (indirect effects: −0.023, −0.027) and depression symptoms (indirect effects: 0.032, 0.037) (all P < 0.001). The subgroup analysis revealed that age, marital status, physical exercise, smoking, and alcohol consumption influenced the impacts of shift work and workplace violence on health. Conclusion Shift work and workplace violence significantly affect healthcare workers' self-rated health and depression symptoms, with job burnout playing a key mediating role in this process. This suggests that healthcare institutions should improve resource allocation, provide flexible scheduling systems, ensure adequate rest time, and increase psychological support and safety measures to help healthcare workers better cope with work-related stress and violence.

Objective To assess the impact of statins combined with sorafenib(SRF)therapy on survival outcomes in patients with metastatic renal cell carcinoma(mRCC).Methods Clinical data of mRCC patients treated in the 908th Hospital of the Joint Security Force from November 2019 to November 2023 were retrospectively analyzed.They were categorized into statin group and non-statin group according to whether they used statins or not,and the differences in the primary endpoint of overall survival(OS),secondary endpoints of progression-free survival(PFS),objective response rate(ORR),and disease control rate(DCR)were compared between the two groups.Results A total of 80 patients were included in the study,with 27 in the statin group and 53 in the non-statin group.There were no statistically significant differences in partial remission,stable disease,disease progression,and DCR between the two groups(P＞0.05);complete remission and ORR were significantly higher in the statin group than in the non-statin group(P＜0.05).Kaplan-Meier analysis showed that,compared with the non-statin group,the median PFS and OS of the statin group were prolonged,and the difference in median PFS between the two groups was statistically significant(P＜0.05).In terms of safety,the incidence of other adverse events was similar in both groups(P＞0.05).Conclusion Statins combined with SRF treatment regimen can improve ORR and DCR and prolong median PFS and OS in patients with mRCC.

End-stage liver diseases,such as cirrhosis and liver cancer caused by hepatitis B,are often combined with hepatic encephalopathy(HE);ammonia poisoning is posited as one of its main pathogenesis mechanisms.Ammonia is closely related to autophagy,but the molecular mechanism of ammonia's regulatory effect on autophagy in HE remains unclear.Sialylation is an essential form of glycosylation.In the nervous system,abnormal sialylation affects various physiological processes,such as neural development and synapse formation.ST3 β-galactoside α2,3-sialyltransferase 6(ST3GAL6)is one of the significant glycosyltransferases responsible for adding α2,3-linked sialic acid to substrates and generating glycan structures.We found that the expression of ST3GAL6 was upregulated in the brains of mice with HE and in astrocytes after ammonia induction,and the expression levels of α2,3-sialylated glycans and autophagy-related proteins microtubule-associated protein light chain 3(LC3)and Beclin-1 were upregulated in ammonia-induced astrocytes.These findings suggest that ST3GAL6 is related to autophagy in HE.Therefore,we aimed to determine the regulatory relationship between ST3GAL6 and autophagy.We found that silencing ST3GAL6 and blocking or degrading α2,3-sialylated glycans by way of Maackia amurensis lectin-Ⅱ(MAL-Ⅱ)and neuraminidase can inhibit autophagy.In addition,silencing the expression of ST3GAL6 can downregulate the expression of heat shock protein β8(HSPB8)and Bcl2-associated athanogene 3(BAG3).Notably,the overexpression of HSPB8 partially restored the reduced autophagy levels caused by silencing ST3GAL6 expression.Our results indicate that ST3GAL6 regulates autophagy through the HSPB8-BAG3 complex.

The killing effect of radiation therapy on healthy cells has led to the creation of targeted radionuclide therapy,which effectively reduces the damage to surrounding normal cells.At present,alpha(α)and beta(β)radionuclides are the research hotspots of targeted therapy.Numerous preclinical and clinical studies have shown that radiation therapy not only has local anti-tumor effects,but also exerts systemic anti-tumor effects by triggering the body's immune response.This paper describes in detail the characteristics and clinical applications of commonly used radionuclides,and discusses the mechanism of radiation-triggered body immune response as well as the related research on the combined use of radiation therapy,targeted radionuclide therapy and immunotherapy.

OBJECTIVE To systematically evaluate the hemostatic effect and safety of snake venom hemocoagulase drugs in abdominal surgery， so as to provide evidence-based evidence for clinic. METHODS Retrieved from Embase， Cochrane Library， PubMed， China Biomedical Literature Database， CNKI and Wanfang database， randomized controlled trials （RCTs） about 3 kinds of snake venom hemocoagulase drugs （Hemocoagulase injection， Hemocoagulase Bothrops atrox for injection， Haemocoagulase Agkistrodon for injection） in abdominal surgery were collected from the establishment of the database to Aug. 2023. Screening， quality evaluation， and data extraction were conducted on literature according to the inclusion and exclusion criteria， and Cochrane 5.1 was used for literature quality evaluation. The risk bias diagram and network diagram were drawn by Stata 15.1 software， and the Bayesian network meta-analysis was carried out by using R 3.6.2 software and Markov chain-Monte Carlo method. RESULTS A total of 11 studies were included， involving 1 401 patients， 852 in the study group， and 549 in the control group. In terms of hemostatic effect， Hemocoagulase injection was significantly superior to Haemocoagulase Agkistrodon for injection [MD＝－2.45， 95%CI （－4.39，－0.24）， P＜0.05]， and the probability of reducing intraoperative bleeding was ranked as follows： Hemocoagulase injection＞hemocoagulase B. atrox for injection＞Haemocoagulase Agkistrodon for injection； in terms of safety， there was no statistically significant difference between the three snake venom hemocoagulase drugs and placebo （P＞0.05）. CONCLUSIONS The hemostatic effect of Hemocoagulase injection in abdominal surgery is significantly better than that of Haemocoagulase Agkistrodon for injection； all three snake venom hemocoagulase drugs have good safety.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Hepatocellular carcinoma is one of the common malignant tumors, and most patients with hepatocellular carcinoma are already in the middle stage at the time of clinical detection, transarterial chemoembolization is the treatment of choice for mid-stage hepatocellular carcinoma.Due to the high degree of tumor heterogeneity, accurately predicting the outcome of patients with hepatocellular carcinoma after transarterial chemoembolization remains one of the difficulties in clinical practice.As an emerging technology, radiomics can not only reflect tumor heterogeneity non-invasively, but also monitor, evaluate and predict tumor progression by analyzing changes in the tumor microenvironment to guide patients′ personalized treatment and prolong their survival time.This article reviews the progress of the application of radiomics in predicting the efficacy of transarterial chemoembolization for hepatocellular carcinoma.

Objective To investigate the influence of limonin on the malignant biological behavior of non-small cell lung cancer (NSCLC) cells by regulating the protein tyrosine kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. Methods CCK-8 method was applied to detect the survival rate of A549 cells treated with different concentrations of limonin (0, 5, 10, 25, 50, 75, 100 μmol/L). A549 cells were separated into normal culture (NC) group, low-dose limonin group (treatment with 10 μmol/L limonin for 24 h), medium-dose limonin group (treatment with 25 μmol/L limonin for 24 h), high-dose limonin group (treatment with 50 μmol/L limonin for 24 h), coumermycin A1 group (treatment with 10 μmol/L JAK2 activator coumermycin A1+50 μmol/L limonin for 24 h), and AG490 group (treatment with 10 μmol/L JAK2 inhibitor AG490+50 μmol/L limonin for 24 h). Clone formation assay was applied to detect the clones of each group of cells. Transwell assay was applied to detect cell migration and invasion, and flow cytometry was applied to detect apoptosis. Western blot analysis was applied to detect the protein expression levels of JAK2, p-JAK2, STAT3, p-STAT3, E-cadherin, N-cadherin, and vimentin in each group. Results The viability of A549 cells decreased significantly in a limonin concentration-dependent manner (P < 0.05), with IC₅₀ of 45.16±1.66 μmol/L. Concentrations of 10, 25, and 50 μmol/L were selected for subsequent experiments. The numbers of clones, migration, and invasion of A549 cells and the protein expression levels of IL-6, p-JAK2, p-STAT3, N-cadherin, and vimentin in the low-, medium-, and high-dose limonin groups significantly decreased, compared with those in the NC group, and the apoptosis rate and E-cadherin protein expression significantly increased (P < 0.05). The JAK2 activator coumermycin A1 attenuated the ability of limonin to inhibit the proliferation, migration, invasion, and other malignant biological behavior of A549 cells and attenuated the apoptosis ability. The JAK2 inhibitor AG490 enhanced the ability of limonin to inhibit the proliferation, migration, invasion, and other malignant biological behavior of A549 cells and enhanced the apoptosis ability. Conclusion Limonin can inhibit the malignant biological behavior of NSCLC cells, such as proliferation, migration, and invasion, by inhibiting the JAK2/STAT3 pathway.
