This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.

Objective:To construct the training course content for gastrointestinal endoscopy nurses based on job competency model.Methods:Based on the job competency model, the training course content for gastrointestinal endoscopy nurses was constructed on the basis of systematic literature search and semi-structured interviews combined with the Delphi expert consultation.Results:A total of 21 experts from nine regions including Beijing City, Hebei Province, Inner Mongolia Autonomous Region, Shanxi Province, Hubei Province, Tianjin City, Guangdong Province, Jilin Province, and Zhejiang Province were selected for consultation. There were two rounds of expert consultation. In the first round of expert consultation, 21 questionnaires were issued and 21 valid questionnaires were recovered, with an effective recovery rate of 100.00%, of which nine experts proposed a total of 38 amendments. In the second round of expert consultation, 21 questionnaires were issued and 17 valid questionnaires were recovered, with an effective recovery rate of 80.95%, of which two experts proposed modifications. For the two rounds of consultation, the expert authority coefficients were 0.871 and 0.882 respectively, and the coefficients of variation for each entry were 0 to 0.16 and 0 to 0.20, and the Kendall's harmony coefficients were 0.272 and 0.217 ( P<0.01). The finalized training course content for gastrointestinal endoscopy nurse based on job competency model consisted of four first-level indicators, 19 second-level indicators, and 53 third-level indicators. Conclusions:The training course content for the gastrointestinal endoscopy nurses constructed based on the job competency model is scientific, generalizable, and practical, and can provide reference and guidance for the training of endoscopic specialty nursing personnel.

Objective To analyse the gene expression profile microarrays of lung adenocarcinoma patients by bioinformatics methods,to study the mechanisms affecting the development of lung adenocarcinoma,and to explore new therapeutic targets for lung adenocarcinoma.Methods The mRNA and miRNA expression data were downloaded from The Cancer Genome Atlas database,key genes were screened by R language and survival analysis and verified by the survival module of the database,and high-expression pathway enrichment analysis was performed for prognostic related genes.Finally,the correlation between key genes and immune cells was analyzed.Results The key disulfide death gene SLC3A2 and key nuclear activation miRNA(hsa-miR-1293)were identified by screening.SLC3A2 was positively correlated with hsa-miR-1293,and the higher the expression,the worse the prognosis of lung adenocarcinoma patients.The most relevant enrichment pathway for SLC3A2 is aminoacyl transfer RNA biosynthesis.SLC3A2 was positively correlated with 4 kinds of differential immune cells and negatively correlated with 4 kinds of differential immune cells.Conclusion Hsa-miR-1293 positively regulates the expression of SLC3A2,a disulfide death gene,to promote the occurrence and development of lung adenocarcinoma,which may provide ideas for developing new therapeutic targets for lung adenocarcinoma.

Objective:To explore the relationship between workplace procrastination and illegitimate tasks in-kindergarten teachersand the role of work disengagement and coworker support in their relationship.Methods:A to-tal of 245 kindergarten teachers were selected from 3 cities in Zhejiang Province.They were assessed with the Workplace Procrastination Scale(WPS),Bern Illegitimate Tasks Scale(BITS),Work Disengagement Scale(WDS),Colleague Support Scale(CSS).The models were tested by using Process macro for SPSS,and non-para-metric percentile bootstrap method was used to analyze the mediating effect and moderating effect.Results:There were significant differences in the total scores of workplace procrastination among kindergarten teachers in different marital status,age,teaching age,education level,teaching gradeand kindergarten level(Ps＜0.05).Work disengage-ment played a significant mediating role between workplace procrastination and illegitimate tasks(indirect effect=0.26,95％CI:0.16-0.37).Coworker support played a significant moderating role in the impact of illegitimate tasks on work disengagement(simple slope=0.72,0.39;P＜0.001).Conclusion:It suggests that workplace pro-crastination is related to illegitimate tasksin kindergarten teachers.Work disengagement plays a mediating role in their relationship,and coworker support plays a moderating role in the first half of this mediating role.

Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.
