| 1 | Association of cancer prevention awareness with esophageal cancer screening participation rates: Results from a population-based cancer screening program in rural China显示文摘Objective: : China have implemented population-based esophageal cancer(EC) screening programs, however,the participant rates were relatively low. This study was conducted to examine the association between cancer prevention knowledge and EC screening participation rates(PRs).Methods: : Data in the analyses were obtained from a population-based cancer screening program in four provinces in China since 2007. In the course of 2007-2016, participants who were evaluated as high risk for EC and subsequently recommended for endoscopy examination were included in the final analysis. One-way analysis of variance test, Chi-square test and logistic regression analysis were applied.Results: : A total of 28,543 individuals assessed as high-risk population for EC were included in this study, with13,036 males(45.67%) and 15,507 females(54.33%). The prevalence rates of current smoking and alcohol drinking were higher in males(58.25% and 44.22%, respectively) than in females(5.35% and 4.05%, respectively).Participants of females, and those who had older age, lower income, as well as higher education level and cancer prevention knowledge level were more likely to undergo endoscopy. Multivariable analysis showed that higher cancer prevention knowledge was associated with higher PR for endoscopic screening [adjusted odd ratio(aORQ4/Q1) =1.511, 95% confidence interval(95% CI): 1.398-1.632] among our study subjects. This association between cancer prevention knowledge and compliance with endoscopic screening also tends to be strong within subgroups of males, females, aged below 60 years, aged 60 years and above, and lower level of education(illiterate individuals and those with junior high education or less).Conclusions: : Our results displayed a positive relationship between cancer prevention knowledge and PRs for endoscopic screening, implying cancer prevention awareness being an independent influence factor for compliance with EC screening. Promoting public campaigns about comprehensive knowledge of cancer prevention seemed to be a reasonable and effective strategy to improve population PRs for EC screening. | Shangchun Jia He Li Hongmei Zeng Rongshou Zheng Jiang Li Jufang Shi Zhixun Yang Maomao Cao Wanqing Chen | 2019 | Chinese Journal of Cancer Research2019，31，4： | 10 |
| 2 | Equation of state of initially liquid carbon monoxide and nitrogen mixture显示文摘The modified liquid perturbation variational theory and the improved vdW-1f model were applied to calculating the equation of the state of liquid CO-N2 mixture with the ratio of 1:1, 4:1 and 1:4, respectively, in the shock pressure range of 9-49 GPa. It was shown that the calculated result for CO-N2 mixture with the ratio of 1:1 is well consistent with the earlier experimental data. The thermodynamics equilibrium, chemical equilibrium and phase equilibrium were all considered in detail. It was found that Hugoniot of liquid CO-N2 mixture is moderately softened in the pressure range of 20-30 GPa and 30-49 GPa for different initial proportions, and that the Hugoniot is more softened in the latter pressure range, which means that the structural phase transition occurs near 20 GPa and 30 GPa. Since the shock pro-ductions may absorb a plenty of systematic energy, the shock temperature and pressure decline compared with the case of no chemical reaction. Pressures and temperatures increase gradually with the increase in the mole fraction of nitrogen composition. The results for the 1:1 CO-N2 mixture lie in the middle of two others. Therefore, it was shown that the modified Lorentz-Berthelor rule used in the scheme is effective to study shock-compression properties of liquid CO-N2 mixture under high temperatures and high pressures. | YANG JinWen SUN Dong SUN Yue SHI ShangChun | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，6： | 0 |
