Alternative splicing of PSMD13 mediated by genetic variants is significantly associated with endometrial cancer risk / 부인종양

Objective@#Accumulating evidence has shown that aberrant alternative splicing events are closely associated with the onset and development of cancer. However, whether genetic variants-associated alternative splicing is linked to risk of endometrial cancer remains largely uncertain. @*Methods@#We identified single nucleotide polymorphisms (SNPs) locates in the splicing number trait locus (sQTL) of endometrial cancer using the CancerSplicing QTL database. In parallel with bioinformatics analysis, we conducted a case-control study comprising 2,000 cases and 2,013 controls to assess the association between identified SNP which possesses mRNA splicing function and endometrial cancer susceptibility. Furthermore, we used the Kaplan-Meier Plotter, The Human Protein Atlas, SPNR, and Spliceman2 databases for sQTL and differential gene expression analyses to identify the genetic variant which most potentially influence the risk of endometrial cancer through alternative splicing to reveal the potential mechanism by which candidate SNPs regulate the risk of endometrial cancer. @*Results@#The results indicated that SNP rs7128029 A

The correlation between electronic cigarette use and environmental exposure to electronic cigarette among residents in Guangzhou City / 预防医学

Objective@#To evaluate the correlation between electronic cigarette (e-cigarette) use and environmental e-cigarette exposure among residents living in Guangzhou City, so as to provide the evidence for the development of the e-cigarette control policy.@*Methods@#Permanent university students living in Guangzhou City were recruited as investigators from July to October 2021, and the permanent adult residents in communities where the university students lived were randomly selected as participants. Subjects' demographic features, e-cigarette use, passive viewing of e-cigarette use and exposure to e-cigarette advertising were collected using both online and offline questionnaire surveys, and the association of e-cigarette use with passive viewing of e-cigarette use and exposure to e-cigarette advertising were examined using a multivariable logistic regression model.@*Results@# A total of 948 questionnaires were allocated, and 874 valid questionnaires were recovered, with an effective recovery rate of 92.19%. The respondents had a mean age of ( 34.96±13.76 ) years. There were 420 men ( 48.05% ), and 426 married residents ( 48.80% ). The prevalence of e-cigarette use was 14.99%, and the rate of e-cigarette use was 23.81% in men and 6.83% in women. In addition, 27.27% of respondents at ages of 35 to 44 years used e-cigarette, 479 respondents viewed e-cigarette advertising ( 54.81% ) and 510 respondents had at least once passive viewing of e-cigarette use ( 58.35% ). Multivariable logistic regression analysis revealed that a higher frequency of exposure to e-cigarette advertising ( OR: 3.064-5.784, 95%CI: 1.683-12.620 ) and a higher frequency of passive viewing of e-cigarette use ( OR: 2.182-2.349, 95%CI: 1.094-4.526 ) led to a higher rate of e-cigarette use.@*Conclusions@#E-cigarette use is affected by passive viewing of e-cigarette use and exposure to e-cigarette advertising among community residents in Guangzhou City. Supervision and restriction is recommended for e-cigarette advertising, marketing, and use in public places.
