Objective:To investigate the mediating effect of social interaction on the relationship between internet use and the health status of the elderly.The findings of this research can potentially contribute new insights into improving the health status of the elderly population.Methods:Based on the data from the Chinese General Social Survey(CGSS)in 2021, a total of 2 675 elderly individuals aged 60 and above were included in the study.The researchers analyzed the linear regression relationship between Internet use, social interaction, and the health status of the elderly using a hierarchical regression model.Additionally, a mediation effect test was conducted using the Bootstrap test.Furthermore, heterogeneity analysis of the mediation effect was performed considering factors such as gender, place of residence, working conditions, and physical exercise among the elderly participants.Results:The total effect value was 0.170.The direct effect of Internet use on the health status of older adults was 0.160(95% CI: 0.078-0.240), accounting for 93.66% of the effect value.The indirect effect of social interaction was 0.011(95% CI: 0.003-0.021), accounting for 6.34% of the effect value.The mediating effect of social interaction on the health status of older adults varied among different groups.Among female elderly, rural elderly, elderly who are currently unemployed, and those who are physically active, the mediating effects were 5.16%, 7.86%, 10.18%, and 9.91%, respectively. Conclusions:The impact of internet use and social interaction on the health status of the elderly is notably positive.Additionally, social interaction partially mediates the relationship between internet use and the health status of the elderly.

Objective To investigate the research status and the research hotspots on male nurses at home and abroad in last decade,so as to provide references for further research in male nurses.Methods Literature between 2013 and 2024 on male nurses were retrieved from the Web of Science(WOS)and CNKI.CiteSpace 6.2.6 R7 software was used to analyse the volume of publication,keyword co-occurrence,keyword clustering and emergence.Results A total of 736 articles were included in the study.From 2013 to 2023,the number of published papers of male nurses in CNKI and WOS showed an increasing trend.The research was primarily affiliated with 263 institutions across 62 countries.The country with the highest volume of publication is China,followed by the United States,although there was a need to enhance collaboration with other nations.The institution with the most publications is the Hong Kong Polytechnic University.A comprehensive analysis of keyword co-occurrence,clustering,and emerging trends revealed that the research hotspots in the field of male nursing in CNKI mainly includes the advantages of male nurses,psychological capital,humanistic care,development,needs,professional identification.Whereas WOS focuses on the topics such as gender bias against male nurses,mental health,workplace violence,ambivalent sexism,motivational barriers,individual differences,societal prejudice and knowledge and attitucle.Both domestic and international research on male nurses primarily consist of cross-sectional surveys and qualitative studies,with fewer intervention studies.Currently,the researches regarding male nursing focus on the qualitative study of mental health of male nurses.Conclusion Focusing on the mental health and professional status of male nurses,domestic scholars need to increase the formulation and implementation of interventions in this field in order to address the practical issues faced by male nurses,therefore to promote the comprehensive development of the nursing profession,enhance the overall quality and service quality of the nursing team,and provide patients with higher quality in nursing services.

Objective To develop and verify the sample size formulas for quantitative data consistency e-valuation based on the least square regression method.Methods According to the principle of least square regres-sion-based quantitative consistency evaluation,statistical inference,and formula derivation,we developed the for-mulas for calculating sample size based on regression constant and regression coefficient.Furthermore,the accuracy of the formulas was verified by the data of three examples,and the results were compared with those of the sample size formula established based on the Bland-Altman(BA)method.Results The sample size formulas for regres-sion-based quantitative consistency evaluation were deduced,and the accuracy of the formulas was verified by three examples.In addition,the results obtained with this formula had differences compared with those of the sample size formula established based on the BA method.Furthermore,consistent conclusions could be obtained by regression analysis and BA analysis with the sample size calculated with the regression method.However,with the sample size calculated based on the BA method,the consistency conclusion of regression analysis and BA analysis was some-times not valid.Conclusion A sample size formula for quantitative consistency evaluation based on the regression method was proposed for the first time,which provided methodological support for the research in this field.

[Purpose]To analyze the trend of incidence and mean age at diagnosis of lymphoma in cancer registration areas of Jiangsu Province from 2009 to 2019.[Methods]Continuous and com-pleted data of cancer incidence from 2009 to 2019 were collected from 16 cancer registries in Jiangsu Province,and all indicators meeting the requirements.Joinpoint 4.7.0.0 software was used to analyze the trend of lymphoma incidence,the average annual percentage change(AAPC)and 95％confidence interval(CI)were calculated.A birth cohort was built from 1929 to 2019,to ana-lyze the change trend of lymphoma incidence rate among people born in different periods.[Re-sults]From 2009 to 2019,the AAPC of lymphoma incidence rate in cancer registration areas of Jiangsu Province was 5.74％,5.55％for men and 5.02％for women.The AAPC in urban areas was higher than that in rural areas(6.26％vs 4.90％).The age-standardized incidence rate(ASIR)of lymphoma increased by 3.40％annually on average.The rising amplitude of ASIR of women(3.16％)was higher than that of men(3.05％),and the rising amplitude of ASIR of lymphoma in urban areas(3.39％)was higher than that in rural areas(2.43％).The birth cohort analysis showed that the incidence rate of lymphoma fluctuated greatly before the age of 40,and there was no sig-nificant trend of change,while the incidence rate in age groups of 40 years old and above showed an overall upward trend.The average age at onset of lymphoma showed an upward trend from 2009 to 2019,with an average annual increase of 0.35 years old(P＜0.001).The standardized average age at onset for lymphoma still showed a significant upward trend,with an average annual increase of 0.15 years old(P=0.016).Compared with 2009,the standardized age specific incidence of lym-phoma in 2019 showed an overall backward trend,while the standardized incidence in all age groups after 60 years old(except for the age group of 70～74 years old)increased.The proportion of lymphoma in people above 60 years old was 56.16％in 2019,which was higher than that in 2009(52.57％).[Conclusion]The incidence rate of lymphoma in Jiangsu Province was increasing year by year from 2009 to 2019.The age at onset tended to shift back,and the trend was more pronounced in male than female.

Osteoarthritis(OA)is a chronic progressive osteoarthropathy in the elderly.Osteoclast activation plays a crucial role in the occurrence of subchondral bone loss in early OA.However,the specific mechanism of osteoclast differentiation in OA remains unclear.In our study,gene expression profiles related to OA disease progression and osteoclast activation were screened from the Gene Expression Omnibus(GEO)repository.GEO2R and Funrich analysis tools were employed to find differentially expressed genes(DEGs).Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses demonstrated that chemical carcinogenesis,reactive oxygen species(ROS),and response to oxidative stress were mainly involved in osteoclast differentiation in OA subchondral bone.Furthermore,fourteen DEGs that are associated with oxidative stress were identified.The first ranked differential gene,heme oxygenase 1(HMOX1),was selected for further validation.Related results showed that osteoclast activation in the pathogenesis of OA subchondral bone is accompanied by the downregulation of HMOX1.Carnosol was revealed to inhibit osteoclastogenesis by targeting HMOX1 and upregulating the expression of antioxidant protein in vitro.Meanwhile,carnosol was found to alleviate the severity of OA by inhibiting the activation of subchondral osteoclasts in vivo.Our research indicated that the activation of osteoclasts due to subchondral bone redox dysplasia may serve as a significant pathway for the advancement of OA.Targeting HMOX1 in subchondral osteoclasts may offer novel insights for the treatment of early OA.

Coronavirus disease 2019 (COVID-19) has yet to be proven to alter male reproductive function, particularly in the majority of mild/asymptomatic patients. The purpose of this study was to explore whether mild/asymptomatic COVID-19 affects semen quality and sex-related hormone levels. To find suitable comparative studies, a systematic review and meta-analysis was done up to January 22, 2022, by using multiple databases (Web of Science, PubMed, and Embase). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify and choose the studies. Meta-analysis was used to examine the semen parameters and sex-related hormones of mild/asymptomatic COVID-19 patients before and after infection. The effects of semen collection time, fever, and intensity of verification on semen following infection were also investigated. A total of 13 studies (n = 770) were included in the analysis, including three case-control studies, six pre-post studies, and four single-arm studies. A meta-analysis of five pre-post studies showed that after infection with COVID-19, sperm concentration (I² = 0; P = 0.003), total sperm count (I² = 46.3%; P = 0.043), progressive motility (I² = 50.0%; P < 0.001), total sperm motility (I² = 76.1%; P = 0.047), and normal sperm morphology (I² = 0; P = 0.001) decreased. Simultaneously, a systematic review of 13 studies found a significant relationship between semen collection time after infection, inflammation severity, and semen parameter values, with fever having only bearing on semen concentration. Furthermore, there was no significant difference in sex-related hormone levels before and after infection in mild/asymptomatic patients. Mild/asymptomatic COVID-19 infection had a significant effect on semen quality in the short term. It is recommended to avoid initiating a pregnancy during this period of time.

Objective: To analyze the genetic characteristics of varicella-zoster virus (VZV) in people aged 20 years and under in Yichang City of Hubei Province from 2019 to 2020. Methods: Based on the Yichang Health Big Data Platform, we investigated cases 20 and under clinically diagnosed as herpes zoster in three hospitals from March 2019 to September 2020. Collecting vesicle fluid and throat swab samples of the cases and completing questionnaires to obtain basic information. Real-time fluorescent quantitative PCR was used for positive identification of the virus. PCR amplification of VZV's open reading frame (ORF) and sequencing of the products to determine the VZV genotype. Analyze mutations at some specific single nucleotide polymorphism (SNP) sites. Results: Among 46 cases of herpes zoster, the male to female ratio was 1.3∶1 (26∶20) and the age ranged from 7 to 20 years old. Fifteen cases had been vaccinated against varicella, including 13 and 2 cases of 1 and 2 doses, respectively. VZV strains were detected in 34 samples (73.91%), all belonging to Clade 2. Phylogenetic tree analysis of the nucleotide of ORF22 showed, compared with Clade 2 referenced strains, the sequence matching degree of nucleotide for all 34 samples was 99.0% to 100.0%. Conclusion: The main VZV strain causing herpes zoster in people aged 20 years and under in Yichang from 2019 to 2020 was Clade 2.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Objective To compare the safety and efficacy of decitabine combined with unrelated umbilical cord blood transplantation and traditional regimen in the elderly patients with acute myeloid leukemia(AML)after achieving complete remission with induction therapy.Methods Fifty-two elderly AML patients who obtained complete remission(CR)after 1-2 cycles of induction therapy in the Department of Hematology of Yancheng First People's Hospital and the Huai'an First Hospital Affiliated to Nanjing Medical University from January 2019 to January 2022 were enrolled,and were divided into the observation group(n=24)and the control group(n=28).The observation group received decitabine combined with unrelated umbilical cord blood transplantation,and the control group received traditional consolidation therapy,including azacitidine+vinblastine,idarubicin+cytarabine(IA),or aclarubicin+cytarabine+granulocyte colony-stimulating factor,and so on.The hematopoietic recovery time,adverse reactions,relapse-free survival(RFS),and overall survival(OS)were compared between the two groups.Results The median recovery time of neutrophils was 12.54 d in the observation group and wes 18.64 d in the control group(P＜0.001);the median recovery time of platelets was 12.67 d in the observation group and was 19.71 d in the control group(P＜0.001).There was no difference in incidences of grade Ⅲ-Ⅳ myelosuppression and non-hematological toxicity between the two groups.There were statistical differences in the median RFS(33 months vs 11 months)and OS(36 months vs 24 months)between the observation group and the control group(P＜0.05).Conclusions Compared with the traditional consolidation regimen,decitabine combined with unrelated umbilical cord blood transplantation for consolidation of AML after achieving remission is more effective in elderly patients,could prolong survival,and has similar safety.

ObjectiveTo evaluate the ABHD5 expression in pan-cancer and its correlations with the main clinical stages， prognosis and immune cell infiltration. MethodsGTEx， TCGA， TIMER2.0， CPTAC databases， immunohistochemistry and western blot were used to analyze the expression levels of ABHD5 in different cancer tissues and adjacent tissues as well as correlations between ABHD5 expression and the main clinical stages. Kaplan-Meier Plotter， Oncolnc and R2 databases were used to explore the prognostic value of ABHD5. The relationship between ABHD5 and immune cell infiltration was analyzed by TCGA and TIMER2.0 databases. STRING and GEPIA databases were used to detect ABHD5-binding proteins and co-expression genes， which were then analyzed by GO and KEGG. ResultsThe mRNA and protein expression levels of ABHD5 were lower in cancer tissues than those in normal tissues in multiple cancer types， but higher in few cancer types. High-level expression of ABHD5 was related to better prognosis in 8 cancer types and related to worse prognosis in 2. ABHD5 expression levels were positively correlated with immune cell infiltration in 9 cancer types， and were the same with neutrophil infiltration and expression of immune checkpoints in pan-cancer. Enrichment analysis showed that ABHD5 was related to histone demethylation. ConclusionPossibly used as a potential prognostic predictor in pan-cancer， ABHD5 was also correlated with neutrophil infiltration， expression of immune checkpoints and histone demethylation.
