Objective:To explore the interactive relationship between health-related quality of life (HRQOL) and anxiety, depression, and fear of progression in patients with advanced prostate cancer and their spouses, providing a basis for developing targeted psychological interventions and improving quality of life.Methods:Convenience sampling was used to select 113 pairs of patients with advanced prostate cancer and their spouses at the First Affiliated Hospital with Nanjing Medical University from September 2023 to August 2024 for the study. General Information Questionnaire, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30), Patient Health Questionnaire-4 (PHQ-4), and Fear of Progression Questionnaire were used to conduct a survey on research subjects. The interactive relationship between variables was analyzed using R software based on the actor-partner interdependence model.Results:A total of 226 questionnaires were distributed and 226 valid questionnaires were recovered, with a valid recovery rate of 100.00%. The PHQ-4 anxiety score, Fear of Progression Questionnaire, and EORTC QLQ-C30 scores of spouses of 113 patients with advanced prostate malignancy were 3.35 (2.25, 4.22), (34.07±9.86), and (57.20±19.48), respectively, which were higher than 2.50 (1.52, 4.45), (30.87±8.85), and (55.47±22.58) of 113 patients, and the differences were statistically significant ( P<0.05). PHQ-4depression scores of the patients and spouses were 2.24 (1.25, 3.57) and 2.56 (1.55, 3.62), respectively, the difference was not statistically significant ( P>0.05). The fitting results based on the actor-partner interdependence model showed that for the subject effect, anxiety (β'=-0.441, -0.452; P<0.01), depression (β'=-0.574, -0.574; P<0.01), and fear of progression (β'=-0.253, -0.435, P<0.05) in patients with advanced prostate cancer patients and their spouses were all predictors of HRQOL, and the differences were all statistically significant. For the object effect, spousal anxiety (β'=-0.372, P<0.01) and fear of progression (β'=-0.312, P<0.01) predicted patients' HRQOL, with statistically significant differences. Conclusions:Spouses of patients with advanced prostate cancer had higher levels of anxiety, fear of progression. Anxiety, depression, and fear of progression all have a negative subject effect on HRQOL for patients and spouses, and spousal anxiety and fear of progression have a negative object effect on HRQOL for patients. Providing effective psychological interventions to address spouses' anxiety and fear of progression can improve HRQOL of patients with advanced prostate cancer and their spouses.

Objective·To analyze the expression changes of adhesion G protein-coupled receptor F1(ADGRF1)in the occurrence and development of pancreatic ductal adenocarcinoma(PDAC),and explore the impact of ADGRF1 on the proliferation of PDAC cells and the potential molecular mechanisms that promote PDAC progression.Methods·The expression of ADGRF1 at mRNA level was analyzed based on the Gene Expression Omnibus(GEO)database and The Cancer Genome Atlas(TCGA)database,respectively.The expression of ADGRF1 in normal pancreatic ductal epithelial cells(hTERT-HPNE)and various PDAC tumor cells was detected by using real-time fluorescence quantitative PCR(qPCR)and Western blotting.Immunohistochemical staining(IHC)was used to detect the differential expression of ADGRF1 in cancer tissues and adjacent tissues of PDAC patients.After knocking down ADGRF1 with small interfering RNA(siRNA)transfection,the changes in the proliferation ability of PDAC AsPC-1 and SW1990 cells were detected through CCK8 assay and plate cloning experiment.Stable overexpression of ADGRF1 was constructed in PDAC Patu8988 cell line,and the proliferation changes induced by overexpression of ADGRF1 were evaluated through CCK8 assay.RNA sequencing(RNA-seq),gene set enrichment analysis(GSEA),and immune infiltration analysis were utilized to predict signaling pathways associated with ADGRF1-mediated promotion of PDAC cancer progression.Results·Analysis of the TCGA database and GEO database revealed higher expression of ADGRF1 mRNA in PDAC tissues compared to normal pancreatic tissues(all P=0.000).qPCR and Western blotting results demonstrated up-regulation of ADGRF1 mRNA and protein levels in various PDAC cells compared to hTERT-HPNE cells(all P<0.05).IHC results confirmed higher ADGRF1 expression in PDAC cancer tissues compared to adjacent tissues.Furthermore,downregulation of ADGRF1 inhibited the proliferation of PDAC AsPC-1 and SW1990 cell lines,while overexpression of ADGRF1 promoted the proliferation of Patu8988 cells(all P<0.05).RNA-seq,GSEA enrichment analysis,and immune infiltration analysis revealed that ADGRF1 expression was related to signaling pathways such as interferon-α(IFN-α),tumor necrosis factor-α(TNF-α),and nuclear factor κB(NF-κB).Conclusion·ADGRF1 is highly expressed in PDAC cells and tissues,and promotes the proliferation of PDAC cells via immune-related signaling pathways.

Objective·To establish a mouse model with dormant cancer and no obvious metastasis by combining the preimmune strategy with the mVenus-p27K-cell G0 phase indicator system,the DTR-HSV/TK suicide gene system,and the Luc2-tdTomato tracer system.Methods·The KPC1199 mouse pancreatic cancer cell line was transfected with the mVenus-p27K-cell G0 phase indicator system,the DTR-HSV/TK suicide gene system,and the Luc2-tdTomato tracer system to construct a stable expression cell line,KPC1199-PDL.After being cultured in the serum-free condition,KPC1199-PDL cells were sorted into mVenus(+)cells and mVenus(-)cells by flow cytometry,and the expression of G0 phase-related genes was verified by real-time fluorescence quantitative PCR(qPCR).Sensitivity of KPC1199-PDL cells to diphtheria toxin(DTX)and ganciclovir(GCV)was evaluated by CCK-8 assay.A transsplenic portal vein-hepatic metastasis model was constructed in wild-type C57BL/6 mice to validate the function of KPC1199-PDL cells in vivo by immunofluorescence technology.The KPC1199-PDL cells were injected subcutaneously into C57BL/6 mice,followed by in situ injection of DTX and GCV to ablate subcutaneous tumors 5 d later,to obtain preimmunized mice.The transsplenic portal vein-hepatic metastasis models were constructed in these mice.Bioluminescence imaging was used to evaluate subcutaneous tumor ablation and hepatic metastasis in the mice,and immunofluorescence assay was used to detect the distribution and dormant state of tumor cells in the livers of preimmunize mice.Results·The three tool systems were stably expressed in KPC1199-PDL cells,and their proliferative ability was not affected.In the serum starving condition,some KPC1199-PDL cells expressed the mVenus protein,indicating entry into the G0 phase;the mVenus(+)cells sorted out by flow cytometry exhibited significantly higher expression of G0 phase-related genes(all P<0.05)and significantly lower expression of the proliferation-related gene compared with mVenus(-)cells(P<0.05).The CCK-8 assay demonstrated high sensitivity of KPC1199-PDL cells to DTX and GCV.In vivo experiments confirmed that KPC1199-PDL cells could be effectively traced through tdTomato protein expression,and could indicate entry into the G0 phase through mVenus protein expression.Following subcutaneous tumor implantation and drug ablation,preimmunized mice were successfully obtained.In the subsequent transsplenic portal vein-hepatic metastasis model,no metastatic signals were observed in the liver by bioluminescence imaging,but single or small clusters of G0 phase tumor cells expressing both mVenus and tdTomato,not expressing the proliferation marker Ki67,were detected in liver tissue sections by immunofluorescence analysis.Conclusions·A recognizable and traceable dormant cancer model is constructed with the combination of the preimmune mouse model of pancreatic cancer,the mVeneus-p27K-indicator system,the DTR-HSV/TK suicide gene system,and the Luc2-tdTomato tracer system.

High-altitude regions,characterized by their elevated altitude,are subject to a complex set of environmental conditions including intense ultraviolet radiation,low oxygen levels,low temperatures,and low humidity.These distinctive environmental features lead to unique dietary patterns,lifestyles,and physiological adaptations.Notably,individuals who have just moved into high-altitude areas and those who live there on a long-term basis undergo specific adaptive adjustments in glucose metabolism.Typically,newcomers experience transient elevations in blood glucose levels,which gradually decline after prolonged residence at high altitudes to levels even lower than those found at low altitudes.In general,current findings of observational studies generally suggest a decreased risk of diabetes mellitus among populations inhabiting high-altitude regions.However,the glucose metabolism varies among populations from different high-altitude regions across the world,which indicates that the reshaping of glucose metabolism induced by high altitudes is a complicated phenomenon.This article provides an overview of the impact of various components of high-altitude environment,characteristic lifestyle factors,and socioeconomic development levels on glucose metabolism and the related diseases and the potential mechanisms involved.The aim is to offer valuable insights for researchers investigating glucose metabolism in high-altitude settings.

Through expert consultation, project analysis, the scale items were screened, and Participation Intention of Nurses on Internet plus Nursing Service Scale was initially formed. The convenient sampling method was adopted to select 825 nurses from6 hospitals in Jiangsu Province (2 ClassⅢ hospitals, 2 ClassⅡ hospitals and 2 ClassⅠ hospitals) from October to December 2020 to conduct a formal survey to test the validity of the questionnaire.Results:The Participation Intention of Nurses on Internet plus Nursing Service Scale included 3 subscales (participating behavioral attitude, subjective behavioral norms and perceived behavioral control) , 8 dimensions and 17 items. The Cronbach 's α coefficient of the total scale was 0.927, and the test-retest reliability coefficient was 0.805.The correlation coefficient between nurses ' willingness to participate in "Internet plus Nursing Service Scale" and participating behavior was 0.743 ( P<0.01) . Factor analysis extracted 8 common factors, and the cumulative variance contribution rate was 72.33%. Conclusions:The Participation Intention of Nurses on Internet plus Nursing Service Scale has good reliability and validity, which can be used to evaluate the "Internet plus Nursing Service" participation behavior willingness of nurses.

Objective:To screen risk factors of postoperative venous thromboembolism (VTE) in patients in department of spinal surgery and establish a risk prediction model and conduct external validation.Methods:This study was a case-control study. Using the convenient sampling method, a total of 93 patients with VTE who underwent spinal surgery from May 2019 to April 2021 in the Second Xiangya Hospital of Central South University were selected as as the thrombosis group, while 100 patients who underwent spinal surgery without VTE during the same period were selected as the control group. A self-designed questionnaire about the risk factors of VTE in patients undergoing spinal surgery was used to investigate the patients. Binomial Logistic regression was used to analyze the risk factors of postoperative VTE in patients with spinal surgery and R software was used to establish a nomogram prediction model. A total of 46 patients (23 patient with VTE and 23 patients without VTE) from Department of Spinal Surgery from May and June 2021 were selected to verify the prediction model.Results:Age ( OR=1.603, 95% CI: 1.036-2.483) , operation time ( OR=0.253, 95% CI: 0.123-0.518) , use of internal fixation ( OR=0.128, 95% CI: 0.043-0.384) , application of bone cement ( OR=0.176, 95% CI: 0.048-0.652) , D-dimer ( OR=0.360, 95% CI: 0.147-0.884) and plasma fibrinogen degradation product ( OR=0.024, 95% CI: 0.006-0.091) were risk factors for VTE in spinal surgery patients. The prediction model was established according to the risk factors. The prediction agreement rate of the model was 0.865 and the sensitivity was 0.742. The model was externally validated with a sensitivity of 0.761, a specificity of 0.565 and an area under the receiver operating characteristic curve of 0.810. Conclusions:Age, operation time, use of internal fixation, application of bone cement, D-dimer and plasma fibrinogen degradation products are risk factors for postoperative VTE in patients with spinal surgery. Predictive models based on risk factors can predict the risk of VTE in spinal surgery patients.

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

Objective:To investigate the prevalence and risk factors of diabetic retinopathy (DR) in patients in Tibet.Methods:A total of 239 patients with DR who received treatment in Department of Endocrinology and Metabolism, Hospital of Chengdu Office of People's Government of Tibet Autonomous Region from December 2017 to December 2018 were included in this study. They were divided into Han nationality and Zang nationality groups according to ethnicity. The condition of DR was evaluated with nonmydriatic ocular fundus photography according to the staging criteria of the severity of retinopathy.Results:The prevalence of DR in Tibet was 18.0％. The prevalence of DR in Tibetan and Han patients with diabetes was 17.5% and 19.2%, respectively. There was no significant difference in the prevalence of DR between Tibetan and Han patients with diabetes ( χ2 = 0.10, P = 0.754). Logistic regression analysis revealed that the risk factors of developing DR in Tibet included diabetes duration ( OR = 1.14, 95% CI: 1.05-1.24, P < 0.05), insulin therapy ( OR = 2.74, 95% CI: 1.09-6.89, P < 0.05), fasting plasma glucose ( OR = 1.37, 95% CI: 1.07-1.75, P < 0.05) and hypertension ( OR = 1.98, 95% CI: 1.02-3.86, P < 0.05). Diabetes duration and fasting plasma glucose are independent risk factors of DR. However, although elevated glycated hemoglobin levels were high in Tibet, they could not be used to predict the risk for developing DR ( OR = 1.01, 95% CI: 0.82-1.25, P > 0.05). Conclusion:Hyperglycemia is an important risk factor of developing DR in Tibet. However, elevated glycated hemoglobin levels cannot be used to predict the risk of developing DR in Tibet. Findings from this study fill the gap in the research on DR prevalence and ethic difference of DR prevalence, providing scientific evidence for prevention and treatment of DR in high-altitude areas.
