Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Mild cognitive impairment （MCI） is a critical precursor stage of Alzheimer’s disease， and the development of MCI is closely associated with liver function. As a core metabolic organ， the liver regulates cognitive function through the liver-brain axis. Epidemiological studies have shown the association between liver function parameters and MCI. The liver affects cognitive function by clearing peripheral β-amyloid （mainly via the PPARα-LRP-1 pathway）， secreting hepatic factors such as FGF21 and sEH to modulate neuronal energy metabolism， and mediating oxidative stress and systemic inflammatory responses. Anti-inflammatory/antioxidant measures， dietary pattern adjustments， and aerobic exercise are currently effective strategies for regulating liver function and mitigating mild cognitive impairment. This article systematically reviews the role and mechanism of the liver-brain axis in MCI， in order to provide new perspectives for developing liver-targeted therapies for cognitive impairment.

The introduction of immunotherapy has changed the traditional paradigms in cancer treatment and has demonstrated substantial clinical benefits across various malignancies. However, this progress is accompanied with emerging challenges, such as immune evasion and low response rates to immunotherapy. As an immunomodulatory molecule, zymogen granule protein 16 (ZG16) plays a crucial role in immunotherapy by inhibiting the binding of programmed death 1 (PD-1) to its ligand PD-L1, preventing immune evasion and restoring the immune system's ability to recognize and eliminate tumor cells. ZG16 is downregulated in multiple gastrointestinal tumors, and its regulatory mechanisms vary depending on the tumor type. ZG16 expression is closely associated with patient prognosis, and it has been identified as a favorable prognostic marker in colorectal cancer. This article provides a systematic overview of the structural characteristics, expression regulation mechanisms, and antitumor immune functions of ZG16.

OBJECTIVE: This study explored the job choice preferences of Center for Disease Prevention and Control (CDC) workers to provide CDC management information and recommendations for optimizing employee retention and motivation policies. METHODS: A discrete choice experiment was conducted in nine provinces across China. Seven key attributes were identified to analyze the job preferences of CDC workers. Mixed logit models, latent class models, and policy simulation tools were used. RESULTS: A valid sample of 5,944 cases was included in the analysis. All seven attributes significantly influenced the job choices of CDC workers. Heterogeneity analyses identified two main groups based on different levels of preference for attribute utility. Income-prioritizers were concerned with income and opportunities for career development, whereas bianzhi-prioritizers were concerned with bianzhi and welfare benefits. The policy simulation analysis revealed that income-prioritizers had a relatively higher sensitivity to multiple job preference incentives. CONCLUSION Income and bianzhi were the two key attributes influencing the job choices and retention preferences of CDC workers. Heterogeneity in job preferences was also identified. Based on the preference characteristics of different subgroups, policy content should be skewed to differentiate the importance of incentives.

Objective:To describe the positive rates of high-risk human papillomavirus (HR-HPV) DNA and serum-neutralizing antibody in cervical intraepithelial neoplasia (CIN) tissues of rural women in Xiangyuan County, Shanxi Province, and evaluate the association of HR-HPV DNA and neutralizing antibody positive status with the occurrence of CIN.Methods:In a cohort of 1 897 women aged 35-45 years established by the Shanxi Province Cervical Cancer Screening StudyⅠ, DNA typing (SPF10 PCR-DEIA-LiPA25) was performed by using tissue samples of women with positive HR-HPV test results [Hybrid CaptureⅡ(HC2)] or abnormal cytological or pathological results. Serum HR-HPV neutralizing antibody detection was conducted with multicolor pseudovirion-based neutralization assay. Cochran-Armitage trend test was used to analyze the changing trend of the positive rate of HR-HPV DNA and neutralizing antibody with the progression of CIN. Multivariate logistic regression models were used to evaluate the influence and multiplicative interaction of HR-HPV DNA and neutralizing antibody positive status on the occurrence of CIN. The relative excess risk ( RERI), attributable proportion of interaction ( AP), and the synergy index ( SI) of the interaction were calculated to evaluate the additive interaction of HR-HPV DNA and neutralizing antibody on the occurrence of CIN. Results:The positive rate of any type of HR-HPV DNA (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) in 479 women who were HC2 positive or had abnormal cytological or pathological detection results was 37.16%. In normal, CIN1, CIN2, and CIN3+ groups, the HR-HPV DNA positive rates were 18.03%, 49.53%, 90.24% and 94.59%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 63.88%. In normal, CIN1, CIN2, and CIN3+ groups, the positive rates of HR-HPV neutralizing antibody were 63.95%, 57.94%, 70.73%, and 72.97%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 53.31% in 1 418 women who were HC2 negative and had normal cytopathology, and the most common types were HPV51 (27.36%) and HPV39 (24.96%). Multivariate logistic regression analysis showed that any type of HR-HPV DNA positive status ( OR=9.15, 95% CI: 5.99-14.20, P<0.001) was the independent factor for the occurrence of CIN, HR-HPV neutralizing antibody positive status was not associated with the occurrence of CIN ( OR=0.95, 95% CI: 0.61-1.48, P=0.815). The OR value of the multiplication of HR-HPV DNA and neutralizing antibody positive status of the occurrence of CIN was 1.63 (95% CI: 0.67-3.95), P=0.283. Quantitative analysis of interaction showed that RERI was 1.65 (95% CI:-3.56-6.86), SI was 1.28 (95% CI: 0.58-2.82), and AP was 0.19 (95% CI:-0.36-0.75). Conclusions:HR-HPV DNA positive status was a risk factor for the occurrence of CIN, but neutralizing antibody positive status was not associated with the occurrence of CIN. They had no significant multiplicative or additive interaction with the occurrence of CIN.

Pharmacoepidemiology is a scientific discipline that applies epidemiological principles and methods to study the utilization and effects of pharmaceuticals in populations.It plays a crucial role in promoting rational drug use and improving public health outcomes.High-quality pharmacoepidemiological research relies on rigorous methodological frameworks.Chinese Pharmaceutical Association(CPA)has officially initiated the development/revision of the of the Guide on Methodological Standards in Pharmacoepidemiology in China(2nd edition)in 2024.This revision project was supported by the Pharmacoepidemiology Committee of CPA,and was led by the Department of Epidemiology and Biostatistics at Peking University School of Public Health,which provided methodological guidance,in collaboration with multidisciplinary experts from across the country.Building on the experience of the 1st edition's development,the working group conducted a qualitative systematic review,to extract key information from global pharmacoepidemiology-related guidelines,laying the foundation for the development/revision proposals of the 2nd edition.Subsequently,through two rounds of Delphi method expert consultations and qualitative interviews,alongside extensive discussions within the working group,the draft revision of the guideline was created.Finally,through an expert consensus meeting using the Nominal Group Technique(NGT),a consensus was reached,resulting in a methodological guideline that integrates international perspectives with local applicability for pharmacoepidemiological research in China.The 2nd edition consists of 41 entries,including 8 primary entries,20 secondary entries,and 13 tertiary entries.It comprehensively covers key aspects such as study protocol development,study implementation,adverse event reporting,research report writing,and dissemination of study findings.Additionally,it addresses specific application scenarios and topics,as well as the application of artificial intelligence and real-world studies.

Pharmacoepidemiology is an interdisciplinary discipline that applies epidemiological research methods to evaluate the application and effect of drugs within population.Standardizing pharmacoepidemiological research methods is crucial for ensuring the quality of research and promoting the development of the discipline.The Pharmacoepidemiology Professional Committee of Chinese Pharmaceutical Association developed the Guide on Methodological Standards in Pharmacoepidemiology(1st edition),in 2019,but has not been updated in over five years.Other,countries/regions such as Europe,America,Japan and South Korea have made a lot of progress in developing and updating the guidelines.Therefore,the rapid development of pharmacoepidemiology in our country and the growing need to align with international standards make it essential to update the guidelines.The second edition of the guidelines was developed through a process that included systematic reviews,practical surveys,and multidisciplinary collaboration.Compared with the first edition,the updated version has made many important changes in research design,data sources,specific application scenarios and more,and added new contents such as the application of artificial intelligence.The purpose of this paper is to emphasize the necessity of updating the guidelines,selecting important changes and formulating interpretation plans.It aims to provide references for relevant professionals to comprehensively understand and apply the new guidelines,and to promote the standardized development and quality of pharmacoepidemiologic research in our country,further advancing the field.
