ObjectiveTo explore the difference in quality of life in patients with gastrointestinal cancer between those who knew cancer diagnosis and those who did not.Methods 130 patients with recently diagnosed gastrointestinal cancer in 4 general hospitals in Tangshan were interviewed. Patients were categorized into two groups:one group was those who knew their diagnosis(n=62) and the other group was those who did not ( n =68).The Chinese version of European Organization for Research and Treatment (EORTC) quality of life (QOL)questionnaire (QLQ-C30) was used.ResultsThe comparison of quality of life between patients who knew their diagnosis and those who did not indicated that the score of global quality of life and other functional scales including physical,emotional,role and cognitive functioning did not show significant difference(P ＞ 0.05 ).Compared with those who did not know cancer diagnosis,patients who were aware of diagnosis showed a significant lower degree of social functioning ( (45.8 ± 24.2 ) vs ( 73.0 ± 16.2 ) ),a significant higher degree of fatigue ( ( 55.8 ±26.2) vs (41.8 ±10.2) ) and financial difficulties ((38.2 ±35.1) vs (12.00 ±10.0) ) (P＜0.01).In multiple regression analysis,physical functioning and symptom of fatigue had statistically significant differences (P＜ 0.05 ).ConclusionThe knowledge of cancer diagnosis does not contribute to the quality of life in patients with gastrointestinal cancer.

Objective To explore the mediation effect of emotional intelligence in social support and subjective happiness,and to provide practical guidance for scientific management of nursing talents in hemodialysis center.Methods Using a cross-sectional study,by a proportional stratified sampling method,from October 2022 to January 2023,800 hemodialysis nurses in Guangzhou area were selected as the respondents,using the general data adjustment table,general well-being schedule(GWB),social support rating scale(SSRS),and wong law emotional intelligence scale(WLEIS-C).The pearson correlation was used to analyze the correlation between emotional intelligence,social support and subjective happiness of hemodialysis nurses in Guangzhou;the process macro program was used to explore the mediation effect of emotional intelligence in social support and subjective happiness in Guangzhou.Results 707 valid questionnaires were collected,and the effective recovery rate was 88.38%.The total score of subjective well-being of hemodialysis nurses in Guangzhou was(75.67±8.17),the total score of emotional intelligence(82.29±16.20),and the total score of social support(38.76±8.40).The total score of social support was positively associated with the total score of subjective well-being(r=0.517,P<0.01)and the total score of emotional intelligence(r=0.633,P<0.01),the total score of emotional intelligence was positively related to the total score of subjective well-being(r=0.634,P<0.01).Social support had a direct effect on subjective well-being(β=0.165,95%CI:0.103-0.261),and indirectly affected it through the partial mediation effect of emotional intelligence(β=0.095,95%CI:0.069-0.142),and the indirect mediation effect accounted for 36.54%of the total effect.Conclusion Guangzhou area hemodialysis nurses subjective well-being is in upper level,and emotional intelligence in hemodialysis nurses social support and subjective happiness plays intermediary effect,managers should focus on hemodialysis nurses emotional intelligence,take various measures to improve their emotional intelligence level,enhance social support,so as to improve hemodialysis nurses subjective well-being.

Objective·To explore the expression of sorting nexin 1(SNX1)in colorectal cancer(CRC)and its impact on the proliferation and migration of CRC cells.Methods·Transcriptomic data and clinical pathological information of CRC were obtained from The Cancer Genome Atlas(TCGA),Genotype-Tissue Expression(GTEx),and Gene Expression Omnibus(GEO)databases for enrichment analysis with Gene Set Enrichment Analysis(GSEA)software.The expression of SNX1 in CRC tissues and cells was detected by quantitative real-time polymerase chain reaction(qPCR),Western blotting,and immunohistochemistry staining(IHC).Small interfering RNA(siRNA)was used to knock down the expression of SNX1 to observe its effect on tumor cell proliferation and migration.Correlation analysis was conducted to explore the potential molecular mechanisms underlying SNX1-mediated CRC cell migration,and mRNA level validation was performed in SNX1 knockdown cell lines.Results·Analysis of CRC patients data in TCGA and tissue microarrays revealed that SNX1 expression was downregulated in CRC tissues and correlated with tumor diameter and distant metastasis.Knockdown of SNX1 enhanced tumor cell proliferation and migration.The expression of SNX1 was negatively correlated with metastasis associated in colon cancer 1(MACC1),mesenchymal to epithelial transition factor(MET),and Notch;knockdown of SNX1 led to upregulation of these genes.Silencing SNX1 resulted in the downregulation of the epithelial marker cadherin 1(CDH1)and the upregulation of vimentin(VIM)and Snail family transcriptional repressor 1(SNAI1).Conclusion·SNX1 expression was significantly downregulated in CRC tissues and correlated with patient prognosis.Low expression of SNX1 enhanced the proliferation and migration of CRC cells and was associated with the MACC1-MET pathway and EMT.SNX1 may serve as a potential biomarker for poor prognosis and a novel therapeutic target in CRC.
