BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND: Most studies have evaluated disability-adjusted life years (DALYs) of colorectal cancer (CRC) patients based on a set of generic disability weights (DWs). This study aimed to apply local CRC-stage-specific DWs to estimate the burden of DALYs for CRC (CRC-DALYs) in populations in China and consider the influence of local screening coverage of CRC. METHODS: A prevalence-based model was constructed using data from various sources. Years lived with disability (YLDs) were estimated mainly via cumulative prevalence data (based on CRC incidence rates, population numbers, and survival rates), stage-specific proportions of CRC, and DWs of the local population. Years of life lost (YLLs) were calculated based on the CRC mortality rates and standard life expectancies. CRC incidence and mortality rates for the years 2020, 2025, and 2030 were estimated by joinpoint regression, and the corresponding DALYs were predicted. The main assumption was made for CRC screening coverage. Sensitivity analyses were used to assess the impact of population, DWs, and coverage. RESULTS: In 2017, among the Chinese population, the estimated number of CRC-DALYs was 4,303,314 (11.9% for YLDs). If CRC screening coverage rate in China (2.3%) remains unchanged, the overall DALYs in 2030 are predicted to increase by 37.2% (45.1% of those aged ≥65 years). More optimistically, the DALYs would then decrease by 0.7% in 2030 (from 5,902,454 to 5,860,200) if the coverage could be increased to 25.0%. A sensitivity analysis revealed that using local DWs would change the base-case values by 5.7%. CONCLUSIONS The estimated CRC-DALYs in China using population-specific DWs were considerably lower (with a higher percentage of YLDs) than the global burden of disease (GBD) estimates (5,865,004, of 4.6% for YLDs), suggesting the impact extent of applying local parameters. Sustainable scale-up CRC screening needs to be in place to moderate the growth trend of CRC-DALYs in China.

Objective: To investigate the health literacy and its influencing factors among residents in areas out of poverty in Kunming City, so as to provide insights into formulating health education strategies. Methods: A total of 1 916 permanent residents at ages of 15 to 69 years were sampled in three areas out of poverty in Kunming City using the multi-stage stratified random sampling method and probability proportionate to size sampling method from August to October, 2020. Health literacy was investigated using the Questionnaire on the Health Literacy among Chinese Residents, the level of health literacy was analyzed and weighted by the population of the China's Seventh National Population Census. Factors affecting health literacy among residents in areas out of poverty were identified using a multivariable logistic regression model. Results: A total of 1 916 questionnaires were allocated, and 1 908 valid questionnaires were recovered, with an effective recovery rate of 99.58%. The respondents included 997 men (52.25%) and 911 women (47.75%), and had a mean age of (45.58±14.28) years. The level of health literacy was 21.38%. Multivariable logistic regression analysis identified age (15 to 24 years, OR=5.087, 95%CI: 1.573-16.450; 25 to 34 years, OR=6.016, 95%CI: 1.991-18.183; 35 to 44 years, OR=7.526, 95%CI: 2.541-22.289; 45 to 54 years, OR=4.800, 95%CI: 1.640-14.050), educational level (junior high school, OR=5.333, 95%CI: 3.100-9.175; high school/vocational high school/technical secondary school, OR=19.895, 95%CI: 10.418-37.966; college or above, OR=27.580, 95%CI: 12.349-61.597) as factors affecting health literacy among residents in areas out of poverty in Kunming City. Conclusion The level of health literacy is 21.38% among residents in areas out of poverty in Kunming City, and age and educational level are associated factors.

Objectives:To evaluate the cost-effectiveness of typical pharmaceutical smoking cessation intervention strategies in China in the context of primary cancer prevention.Methods:Markov cohort simulation models were established to simulate the burden of 12 smoking caused cancer, including lung cancer, oral cancer, nasopharyngeal cancer, laryngeal cancer, esophageal cancer, gastric cancer, pancreatic cancer, liver cancer, kidney cancer, bladder cancer, cervical cancer, and acute myeloid leukemia. Taking incremental cost effectiveness ratio (ICER) as the main indicator, the model sets one year as the cycling period for 50 periods and simulates the cohort of 10 000 thirty-five-year-old current smokers with various smoking cessation strategies. To ensure the robustness of conclusion, univariate sensitivity analysis, probability sensitivity analysis, and age-group sensitivity analysis were conducted.Results:The results showed that varenicline intervention was the most cost-effective intervention. Compared to the next most effective option, incremental cost of each additional quality-adjusted life year is 11 140.28 yuan, which is below the threshold of willingness to pay (1 year GDP per capita). The value of ICER increased as the increasing age group of adopting intervention, but neither exceeded the threshold of willingness to pay. One-way sensitivity analysis showed that the value of discount rate, the hazard ratio and cost of intervention strategy had a greater impact on the result of ICER.Conclusion:In China, the use of varenicline to quit smoking is highly cost effective in the context of cancer primary prevention, especially for younger smokers.

Objective:To understand the current and integrated disease burden and economic burden caused by breast cancer in females in China.Methods:Based on six updated data sources, including the series of Chinese Cancer Registry Annual Report, China Death Cause Surveillance Datasets, China Health Statistical Yearbook, GLOBOCAN, Cancer Incidence in Five Continents, Global Burden of Disease Study (GBD), the information about incidence, mortality and disability adjusted life years (DALY) of breast cancer were extracted for the analysis on the current incidence and time trend of breast cancer and predicted disease burden of breast cancer in females in China. Software Joinpoint was used for time trend analysis. The data of economic burden were systematically updated and analyzed by literature review.Results:1) GLOBOCAN 2022 estimated that the age-standardized incidence rate (ASIR) age-standardized mortality rate (ASMR) and one- year prevalence rate of breast cancer in females were 33.0/100 000, 6.1/100 000 and 40.1/100 000, respectively, in China in 2022. According to Chinese Cancer Registry Annual Report, the ASIR and ASMR were 28.4/100 000 and 5.8/100 000, respectively, in 2018. The China Death Cause Surveillance Datasets showed that the ASMR was 4.5/100 000 in 2021, and the urban to rural area mortality ratio was 1.2∶1. GBD reported that the DALYs of breast cancer were 2.921 million in China in 2021, accounting for 14.4% of the global total. 2) Chinese Cancer Registry Annual Report data showed that the ASIR and ASMR of breast cancer decreased by 2.1% and 11.4%, respectively, in China from 2009 to 2018, while increased by 43.9% and 8.2% in rural area, respectively. The Joinpoint analysis showed that the average annual percentage change (AAPC) of ASIR and ASMR in China were -0.2% ( P>0.05) and -1.6% ( P<0.05). The AAPC of ASIR and ASMR in rural area were 3.9% ( P<0.05) and 0.6% ( P>0.05), and -0.3% ( P>0.05) and -1.2% ( P<0.05) in urban area, respectively. China Health Statistical Yearbook data showed that the urban ASMR decreased by 12.3% from 2014 to 2021 with AAPC of -2.6% ( P<0.05). 3) The GLOBOCAN 2022 predicted that, the breast cancer case count and death count in China would be 387 776 and 111 133 by 2050, an increase of 8.6% and 48.2%, respectively, compared with 2022, the increases would be more obvious in people over 65 years old, an increase of 80.8% and 124.9%, respectively. 4) Thirteen individual- based studies reported that the median medical expenditure per patient ( M=21 000 to 39 000 Yuan) and length of hospital stay ( M=11.0 to 30.5 days) for breast cancer treatment decreased from 2010 to 2019, while the average medical expenditure per visit ( M=9 000 to 23 000 Yuan) showed an upward trend. There was only one national-level analysis, which showed that the treatment cost of breast cancer was 25.24 billion Yuan in China in 2018, accounting for 6.4% of the total cancer treatment cost. Conclusions:According to the above updated multi-source data, the incidence and mortality of female breast cancer in China were stable in the past ten years, but the increasing trend in rural area should be noted. The direct medical expenditure of breast cancer treatment per case might decrease, but the population-level economic burden would remain heavy due to population aging.

Objective:To systematically integrate and analyze the breast cancer screening rates among females in China and to estimate the composition of different screening service types.Methods:Based on core literature, relevant official websites, projects/survey reports, and information on breast cancer screening rates of Chinese females were extracted and analyzed, and the screening rates for 40-69 years old and 35-64 years old were standardized and compared using 2010 China's population structure. The literature review method was used to retrieve the journal literature related to the composition of breast cancer screening services types (organized screening, physical examination and opportunistic screening). The number of detected literature and the median sample size of individual screening people of the three screening service types were analyzed, and used them as weights to estimate the composition of screening service types.Results:A total of 6 related national surveys on breast cancer screening rate were identified, including 2 from the National Health Service Surveys (broader definition of "breast screening" in 2013, 2018) and 4 from the chronic disease monitoring system of China CDC (the exact definition of "breast cancer screening" in 2010, 2013 and twice in 2015). The age-standardized analysis indicated that 1-year, 2-year and 3-year breast cancer screening rates in 2015 among females in China aged 40-69 years old were 16.9%, 20.2% and 21.4%, respectively. The ever-breast cancer-screened rates were 21.1% in 2013 and 23.5% in 2015 among females aged 40-69, and the corresponding rates were 23.3% and 25.7%, respectively, among females aged 35-64. When taking the literature published in 2015 for further literature review, 130 articles were included, in which the proportions of numbers of reports on organized screening, physical examination, and opportunistic screening were 71.0%, 23.7%, and 5.3%, respectively. Along with the extracted data on median sample sizes (shown in the main text) by breast cancer screening types, it was estimated that the individual service volume of corresponding screening types accounted for 88.0%, 11.2% and 0.8% among all the screened females in China in 2015.Conclusions:The breast cancer screening rates among females of appropriate age in China in 2015 are higher than those in 2013. The literature review analysis preliminarily suggested that the current breast cancer screening service type in China is mainly organized screening service.

Background::Non-smokers account for a large proportion of lung cancer patients, especially in Asia, but the attention paid to them is limited compared with smokers. In non-smokers, males display a risk for lung cancer incidence distinct from the females—even after excluding the influence of smoking; but the knowledge regarding the factors causing the difference is sparse. Based on a large multicenter prospective cancer screening cohort in China, we aimed to elucidate the interpretable sex differences caused by known factors and provide clues for primary and secondary prevention.Methods::Risk factors including demographic characteristics, lifestyle factors, family history of cancer, and baseline comorbidity were obtained from 796,283 Chinese non-smoking participants by the baseline risk assessment completed in 2013 to 2018. Cox regression analysis was performed to assess the sex difference in the risk of lung cancer, and the hazard ratios (HRs) that were adjusted for different known factors were calculated and compared to determine the proportion of excess risk and to explain the existing risk factors.Results::With a median follow-up of 4.80 years, 3351 subjects who were diagnosed with lung cancer were selected in the analysis. The lung cancer risk of males was significantly higher than that of females; the HRs in all male non-smokers were 1.29 (95% confidence interval [CI]: 1.20-1.38) after adjusting for the age and 1.38 (95% CI: 1.28-1.50) after adjusting for all factors, which suggested that known factors could not explain the sex difference in the risk of lung cancer in non-smokers. Known factors were 7% (|1.29-1.38|/1.29) more harmful in women than in men. For adenocarcinoma, women showed excess risk higher than men, contrary to squamous cell carcinoma; after adjusting for all factors, 47% ([1.30-1.16]/[1.30-1]) and 4% ([7.02-6.75]/[7.02-1])) of the excess risk was explainable in adenocarcinoma and squamous cell carcinoma. The main causes of gender differences in lung cancer risk were lifestyle factors, baseline comorbidity, and family history.Conclusions::Significant gender differences in the risk of lung cancer were discovered in China non-smokers. Existing risk factors did not explain the excess lung cancer risk of all non-smoking men, and the internal causes for the excess risk still need to be explored; most known risk factors were more harmful to non-smoking women; further exploring the causes of the sex difference would help to improve the prevention and screening programs and protect the non-smoking males from lung cancers.

A strong animal survival instinct is to approach objects and situations that are of benefit and to avoid risk. In humans, a large proportion of mental disorders are accompanied by impairments in risk avoidance. One of the most important genes involved in mental disorders is disrupted-in-schizophrenia-1 (DISC1), and animal models in which this gene has some level of dysfunction show emotion-related impairments. However, it is not known whether DISC1 mouse models have an impairment in avoiding potential risks. In the present study, we used DISC1-N terminal truncation (DISC1-N
