Socioeconomic inequalities in cancer incidence and access to health services among children and adolescents in China: a cross-sectional study.

Background: Despite the substantial burden caused by childhood cancer globally, childhood cancer incidence obtained in a nationwide childhood cancer registry and the accessibility of relevant health services are still unknown in China. We comprehensively assessed the most up-to-date cancer incidence in Chinese children and adolescents, nationally, regionally, and in specific population subgroups, and also examined the association between cancer incidence and socioeconomic inequality in access to health services.

Methods: In this national cross-sectional study, we used data from the National Center for Pediatric Cancer Surveillance, the nationwide Hospital Quality Monitoring System, and public databases to cover 31 provinces, autonomous regions, and municipalities in mainland China.

Uptake of lung cancer screening with low-dose computed tomography in China: A multi-centre population-based study.

Background: Optimal uptake rates of low-dose computed tomography (LDCT) scans are essential for lung cancer screening (LCS) to confer mortality benefits. We aimed to outline the process model of the LCS programme in China, identify the high-risk individuals with low uptake based on a prospective multi-centre population-based cohort, and further explore associated structural characteristics.

Methods: A total of 221,955 individuals at high-risk for lung cancer from the National Lung Cancer Screening cohort were included.

Risk-stratified Approach for Never- and Ever-Smokers in Lung Cancer Screening: A Prospective Cohort Study in China.

Over 40% of lung cancer cases occurred in never-smokers in China. However, high-risk never-smokers were precluded from benefiting from lung cancer screening as most screening guidelines did not consider them. We sought to develop and validate prediction models for 3-year lung cancer risks for never- and ever-smokers, named the China National Cancer Center Lung Cancer models (China NCC-LC models).

Sex disparity of lung cancer risk in non-smokers: a multicenter population-based prospective study based on China National Lung Cancer Screening Program.

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.

Catalytic oxidation of 4-acetamidophenol with Fe-enhanced Cu particles: In-site generation and activation of hydrogen peroxide.

Cu coupled with O was used to degrade contaminant due to in-site generation and catalysis of HO, while the low reactivity and active dismutation reaction of Cu refrained the performance at acidic condition. In this study, the removal rate of 4-acetamidophenol increased from 27 % to 83.4 % with Fe spiked into the Cu system within 60 min •OH was the primary reactive species in the Fe/Cu system.

One-off low-dose CT for lung cancer screening in China: a multicentre, population-based, prospective cohort study.

Background: Lung cancer is the leading cause of cancer death worldwide. Data on the effectiveness of one-off low-dose CT (LDCT) in reducing lung cancer mortality and all-cause mortality are needed to inform screening programmes in countries with limited medical resources. We aimed to evaluate the effectiveness of one-off LDCT screening in the early detection of lung cancer in China.

Lung cancer risk prediction models based on pulmonary nodules: A systematic review.

Background: Screening with low-dose computed tomography (LDCT) is an efficient way to detect lung cancer at an earlier stage, but has a high false-positive rate. Several pulmonary nodules risk prediction models were developed to solve the problem. This systematic review aimed to compare the quality and accuracy of these models.

BMI changes and the risk of lung cancer in male never-smokers: A prospective cohort study.

Background: To investigate the association between the risk of lung cancer and short-term body mass index (BMI) changes in male never-smokers of a large population-based prospective study.

Methods: A total of 37,085 male never-smokers from Kailuan cohort with at least ≥2 BMI measurements were recruited in the present study. The BMI change in the follow-up was calculated as the annual percent change between BMI at last examination and that at baseline, and categorized into five groups: stable (-0.

Menstrual factors, reproductive history, and risk of lung cancer: a multi-center population-based cohort study in Chinese females.

Background: Female menstrual and reproductive factors, as remarkable indicators of hormone effect, were hypothesized to be associated with lung cancer risk, whereas the existed epidemiological evidence was inconsistent. Our study aims to investigate the association between menstrual and reproductive factors and lung cancer risk based on the Chinese Lung Cancer Screening Program.

Methods: This study was based on a large-scale multi-center population cohort across China recruiting individuals aged 40-74 years old between 2013-2018.

Lung cancer risk in non-smoking females with a familial history of cancer: a multi-center prospective cohort study in China.

Familial risk of lung cancer has been widely studied but whether this association holds in non-smoking females is largely unknown. We sought to determine the relationship between a family history of cancer and lung cancer risk among Chinese non-smoking females based on a multi-center prospective population-based cohort study involving 547,218 individuals between 2013 and 2019. A total of 1620 lung cancer cases occurred during a median follow-up of 3.

Associations between female lung cancer risk and sex steroid hormones: a systematic review and meta-analysis of the worldwide epidemiological evidence on endogenous and exogenous sex steroid hormones.

Background: Published findings suggest sex differences in lung cancer risk and a potential role for sex steroid hormones. Our aim was to perform a meta-analysis to investigate the effects of sex steroid hormone exposure specifically on the risk of lung cancer in women.

Methods: The PubMed, MEDLINE, Web of Science, and EMBASE databases were searched.

Association between pre-diagnostic serum albumin and cancer risk: Results from a prospective population-based study.

Background: Albumin is supposed to be associated with cancer risk. However, evidence on serum albumin and cancer risk among the Chinese population is sparse. This study was conducted to evaluate the association between pre-diagnostic serum albumin and cancer risk among Chinese.

Current situation and trends of online academic activities for oncologists during the COVID-19 pandemic: a multicenter survey.

Background: The present study aimed to investigate the current situation and future trends of online academic activities for oncologists during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: From April 22 to May 5, 2020, a multicenter survey was conducted using an online questionnaire platform. To compare categorical variables, χ-test, the kappa consistency analysis, and Wilcoxon rank sum test were applied.

DNA barcoding reveals cryptic diversity in the underestimated genus Triplophysa (Cypriniformes: Cobitidae, Nemacheilinae) from the northeastern Qinghai-Tibet Plateau.

Background: The northeastern part of the Qinghai-Tibet Plateau (QTP) presents a high number of plateau loach species. As one of the three major groups of fishes distributed on the QTP, plateau loach has high ecological value. However, the taxonomy and systematics of these fish are still controversial, and a large number of new species have been reported.

Risk prediction model for lung cancer incorporating metabolic markers: Development and internal validation in a Chinese population.

Background: Low-dose computed tomography screening has been proved to reduce lung cancer mortality, however, the issues of high false-positive rate and overdiagnosis remain unsolved. Risk prediction models for lung cancer that could accurately identify high-risk populations may help to increase efficiency. We thus sought to develop a risk prediction model for lung cancer incorporating epidemiological and metabolic markers in a Chinese population.
