Cancer has become one of the most significant diseases threatening human life and health. In 2022, there were 19.97 million new cancer cases and 9.74 million cancer-related deaths worldwide, imposing a heavy burden on society. A systematic and comprehensive understanding of the cancer burden is the cornerstone for formulating effective prevention and control strategies. Open-source databases, represented by the GLOBOCAN database and the Global Burden of Disease (GBD) database, provide critical support for obtaining the latest cancer burden data, identifying key areas for prevention and control, guiding screening and early diagnosis and treatment, and evaluating the effectiveness of intervention measures. However, the field of cancer big data also faces challenges, such as insufficient data standardization and inadequate privacy protection mechanisms. In the future, while ensuring patient privacy and security, efforts should be made to further improve data quality, promote data sharing, enhance the equity of cancer prevention and treatment resources, and strengthen international collaboration. These measures will reasonably advance the precision and scientific development of cancer prevention and control strategies, with the aim of reducing the cancer burden and contributing to global health and well-being.

To analyze the disease burden, temporal trends, and attributable risk factors of early-onset female breast cancer (EOBC) in China and globally from 1990 to 2021.

Objective:To evaluate the role of O-sialoglycoprotein endopeptidase (OSGEP) in hepatic ischemia-reperfusion injury (HIRI) and the relationship with oxidative stress in mice.Methods:Experiment Ⅰ Twenty-four SPF healthy male C57BL/6 mice, 12 wild-type and 12 OSGEP knockdown, aged 6-8 weeks, weighing 18-22 g, were divided into 4 groups ( n=6 each) by the random number table method: wild-type shamoperation group (Sham group), wild-type HIRI group (HIRI group), OSGEP knockdown+ sham operation group (Sham+ KD group) and OSGEP knockdown+ HIRI group (HIRI+ KD group). Ischemia-reperfusion model was prepared by blocking the hepatic artery and portal vein for 60 min followed by reperfusion in anesthetized animals, the blood vessels were only exposed without occlusion in Sham group and Sham+ KD group, and the blood vessels were clamped for 60 min followed by reperfusion in HIRI group and HIRI+ KD group. The mice were sacrificed after 6-h reperfusion to extract liver tissue samples for microscopic examination of histopathological changes (with an optical microscope after HE staining) which were evaluated using Suzuki score and for determination of the serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), level of reactive oxygen species (ROS) (using the DCFH-DA fluorescent probe method), contents of malondialdehyde (MDA) and glutathione(GSH) in liver tissues (using a colorimetric method) and expression of OSGEP (using Western blot). Experiment Ⅱ The well-growing AML12 cells were divided into 4 groups ( n=30 each) using a random number table method: control group (C group), oxygen-glucose deprivation/restoration (OGD/R) group, OGD/R+ OSGEP knockdown group (OGD/R+ KD group), and OGD/R+ OSGEP knockdown negative control group (OGD/R+ NC group). Group C was cultured under normal conditions. Group OGD/R was subjected to O 2-glucose deprivation for 6 h followed by restoration of O 2-glucose supply for 24 h in OGD/R group. In OGD/R+ KD group, stable transfection of AML12 cells with OSGEP knockdown was performed prior to the experiment, and the other procedures were the same as those previously described. The cell survival rate was measured by the CCK-8 assay, the release of lactate dehydrogenase (LDH) was measured, the DCFH-DA method was used to detect the levels of ROS, and the contents of MDA and GSH were determined using a colorimetric method. Results:Experiment Ⅰ Compared with Sham group, the expression of OSGEP was significantly down-regulated, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were increased, and the GSH content was decreased in HIRI group ( P<0.05), and no significant change was found in each parameter in Sham+ KD group ( P>0.05). Compared with HIRI group, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were significantly increased, and the GSH content was decreased in HIRI+ KD group ( P<0.05). Experiment Ⅱ Compared with group C, the expression of OSGEP was significantly down-regulated, the cell survival rate and GSH content were decreased, and the release of LDH, levels of ROS and content of MDA were increased in group OGD/R ( P<0.05). Compared with OGD/R group, the cell survival rate and GSH content were significantly decreased, and the release of LDH, levels of ROS and content of MDA were increased in OGD/R+ KD group ( P<0.05), and no significant change was found in each parameter in OGD/R+ NC group ( P>0.05). Conclusions:OSGEP plays an endogenous protective role in HIRI by inhibiting oxidative stress in mice.

Implementation strategies are targeted interventions aimed at promoting the adoption, implementation, and sustainment of research findings or evidence-based practices in routine healthcare. If implementation strategies can precisely match implementation barriers and facilitators, the likelihood of successful implementation will increase. The CFIR-ERIC matching tool, which can match corresponding ERIC implementation strategies based on CFIR barriers, is a convenient and direct tool for developing implementation strategies. This paper provides a detailed overview of the origins and development of the CFIR-ERIC matching tool, outlines its contents and usage, and illustrates how to apply the tool to develop implementation strategies by using a brief smoking cessation intervention project as an example. The paper also discusses the advantages and limitations of using this tool for developing implementation strategies, with the aim of providing methodological reference for other researchers.

Background::Given the recent updates in cancer burden estimates by GLOBOCAN 2022, this study was undertaken to provide pertinent perspectives within the context of the Human Development Index (HDI) and major world economies.Methods::Datasets sourced from GLOBOCAN encompassed cancer cases and deaths across all cancer types in 2022, alongside projections up to 2050. Cancer incidences and deaths of the top 10 cancers within China and four distinct HDI-classified regions were compared using descriptive analyses. Age-standardized incidence rates (ASIRs) and mortality rates (ASMRs) worldwide for the most prevalent cancers in 2022 across ten largest economies and four-tier HDIs were examined. The top five cancer types concerning both incidence and mortality in China were delineated by sex and age group.Results::In males, prostate cancer predominated in countries with low, high (except China), and very high HDI. Prostate and liver cancers were prominent causes of death in countries with low HDI. In females, breast and cervical cancers predominated in countries with low-to-medium HDI. Lung and colorectal cancer incidence and deaths increased with high HDI for both sexes. ASIRs and ASMRs for breast, prostate, lung, and colorectal cancers in the top 10 economies were higher than the global average. However, liver, stomach, and cervical cancers in most Western countries exhibited lower rates. In China, hematologic malignancies (43%) were prevalent among children aged 0–14 years, whereas thyroid cancer led among adolescents and young adults aged 15–39 years. Regarding incidence and mortality, lung cancer predominated for individuals over 40 years, except for females aged 40–59 years, in whom breast cancer predominated. Projected trends indicated substantial increases in new cancer cases (76.6%) and deaths (89.7%) over the next three decades.Conclusions::Infection- and poverty-related cancer burdens are offset by increased prostate, breast, colorectal, and lung cancer incidence associated with rapid societal and economic transitions. Cancer incidence and mortality patterns in China feature characteristics of developed and developing countries, necessitating tailored, evidence-based, and comprehensive strategies for effective cancer prevention and control.

Background::Hepatitis B virus (HBV) infection is the primary cause of hepatocellular carcinoma (HCC) in China. The target population for HCC screening comprises individuals who test positive for hepatitis B surface antigen (HBsAg). However, current data on the prevalence of HBV infection among individuals who are eligible for HCC screening in China are lacking. We aimed to assess the seroepidemiology of HBV infection among Chinese individuals eligible for HCC screening to provide the latest evidence for appropriate HCC screening strategies in China.Methods::Questionnaires including information of sex, age, ethnicity, marital status, educational level, source of drinking water, as well as smoking and alcohol consumption history and serum samples were collected from females aged 45–64 years and males aged 35–64 years in 21 counties from 4 provinces in eastern and central China between 2015 and 2023. Enzyme-linked immunosorbent assay methods were used to detect the serum HBV marker HBsAg.Results::A total of 603,082 individuals were enrolled, and serum samples were collected for analysis from January 1, 2015 to December 31, 2023. The prevalence of HBsAg positive in the study population was 5.23% (31,528/603,082). The prevalence of HBsAg positive was greater in males than in females (5.60% [17,660/315,183] vs 4.82% [13,868/287,899], χ 2 = 187.52, P <0.0001). The elderly participants exhibited a greater prevalence of HBV infection than younger participants (χ 2 = 41.73, P <0.0001). Birth cohort analysis revealed an overall downward trend in HBV prevalence for both males and females. Individuals born in more recent cohorts exhibited a lower prevalence of HBV infection as compared to those born earlier. Conclusions::The current prevalence of HBV infection remains above 5% in populations eligible for HCC screening in China.

Background::Female breast and five gynecological cancers remain substantial burden in China and worldwide. GLOBOCAN 2022 has recently updated the estimates of cancer burden. This study aims to depict the profiles of disease burden and to compare the age-specific rates of female breast and five gynecological cancers in China with those in other countries.Methods::The latest estimates of incidence and mortality of female breast and five gynecological cancers from various regions and countries were extracted from the GLOBOCAN 2022 database. We compared the proportion of total cases or deaths for cancers affecting female breast and five gynecological cancers and other tumor types in China and globally. Correlation analysis was conducted to evaluate the relationship between age-standardized incidence rate (ASIR) or age-standardized mortality rate (ASMR) and the Human Development Index (HDI). Additionally, age-specific rate curves were plotted for ten exemplary countries with different income levels.Results::Female breast and five gynecological cancers in China accounted for 30.2% of all newly diagnosed cancer cases. Breast cancer and cervical cancer are the most commonly diagnosed, with nearly 507,000 new cases, representing 23.48% of the new cases. The incidence rates of breast, uterine corpus, ovarian, and vulvar cancers were positively associated with HDI tiers. Chinese women aged 50-54 years are experiencing high incidence rates of breast, cervix uteri, corpus uteri, and ovarian cancers.Conclusions::Female breast and five gynecological cancers continue to be a significant health concern for women in China and worldwide. It is crucial to implement comprehensive prevention strategies tailored to address the increasing trend among younger individuals and reduce regional disparities.
