This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective: To review the current development of artificial intelligence (AI) technology in the field of transfusion medicine. Methods: A systematic search was conducted in the Clarivate Web of Science Database from inception to December 2024 for literature related to AI and transfusion. A total of 4 775 publications were identified. Based on inclusion and exclusion criteria, 133 original studies were ultimately included and analyzed using a narrative synthesis approach. Results: Research on AI in transfusion has surged since 2020 (accounting for 77% of all publications), with China ranking second globally in publication volume. Among the included studies, 69.2% focused on predicting individual transfusion needs, followed by inventory management (8.3%), diagnosis and prediction of adverse transfusion reactions (6.0%), factors influencing transfusion outcomes (5.3%), blood group identification (5.3%), blood quality testing (4.5%), and precise blood volume measurement (1.5%). Additionally, 4.5% of the studies were published in journals with an impact factor greater than 10; 19.5% developed software or applications; 31.5% were multi-center studies; 48.1% utilized decision tree methods, while 31.5% employed neural network approaches; and 14.2% conducted external validation of the algorithms. Conclusion: AI demonstrates significant potential in transfusion risk prediction, decision support, and blood management. However, challenges remain, including limited model generalizability, insufficient algorithm interpretability, and barriers to clinical translation. The deep integration of AI with transfusion medicine will accelerate the advent of precision transfusion era, maximizing blood resource utilization, reducing waste, and ensuring transfusion safety.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective:To evaluate the association between N-acylsphingosine amide hydrolase 1 (ASAH1) and pyroptosis during acute lung injury (ALI) in septic mice.Methods:Forty SPF-grade healthy male C57BL/6 mice, aged 6-8 weeks, weighing 18-23 g, were divided into 4 groups ( n=10 each) by a random number table method: sham operation group (Sham group), ALI group, HCFU solvent+ ALI group (HA group) and ASAH1 inhibitor HCFU+ ALI group (AA group). The abdominal cavity was only opened in Sham group, and cecal ligation puncture was performed in ALI, HA and AA groups. HCFU solvent 0.2 ml was intraperitoneally injected at 2 h before operation in HA group, and HCFU 10 mg/kg was intraperitoneally injected at 2 h before operation in AA group. The mice were sacrificed at 24 h under deep anesthesia, the eyeballs were removed to collect the blood, the bronchoalveolar lavage fluid (BALF) was collected, and lung tissues and blood samples were collected for microscopic examination of the pathological changes (using HE staining) which were scored and for determination of concentrations of protein in BALF (by BCA method), concentrations of interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) in BALF (by enzyme-linked immunosorbent assay), and expression of NOD-like receptor thermoprotein structural domain-related protein 3 (NLRP3) in lung tissues (by Western blot), gasdermin D protein (GSDMD), ASAH1 and cysteine protease-1 (caspase-1) (by Western blot). The wet/dry lung weight (W/D) ratio was calculated. Results:Compared with Sham group, the lung injury score, W/D ratio and concentrations of protein in BALF, IL-1β, IL-6 and TNF-α in serum were significantly increased, and the expression of NLRP3, GSDMD and caspase-1 in lung tissues was up-regulated in ALI, HA and AA groups, and the expression of ASAH1 was significantly up-regulated in ALI and HA groups ( P<0.05). Compared with ALI and HA groups, the lung injury score, W/D ratio, and concentrations of protein in BALF, IL-1β, IL-6 and TNF-α in serum were significantly increased, the expression of NLRP3, GSDMD and caspase-1 in lung tissues was up-regulated, and the expression of ASAH1 was down-regulated in AA group ( P<0.05 or 0.01). Conclusions:ASAH1 is involved in the endogenous protective mechanism underlying ALI in septic mice, which may be related to the inhibition of cell pyroptosis.

OBJECTIVE To design and synthesize novel α-naphthylthiol amino acid ester lysine specific demethylase 1(LSD1) inhibitors, evaluate their inhibitory activity with selectivity against LSD1, and explore their binding mechanism through molecular docking and dynamics simulation.

All the compounds were evaluated for their inhibitory activity against LSD1 at concentrations of 5.0 and 1.0 μmol·L–1 using the LSD1 screening platform of research group. The most potent compound was tested for its IC50 value and enzyme selectivity over MAO-A and MAO-B, and its binding mode was investigated through molecular docking and dynamics simulation. RESULTS A total of 13 compounds were obtained, all of which exhibited significant inhibitory effects on LSD1. Among them, nine compounds showed an inhibitory rate of over 50.0% against LSD1 at a concentration of 1.0 μmol·L–1, while compound 3l displaying the best activity with an IC50 value of 0.17 μmol·L–1, 174 times higher than the positive control. It also showed excellent selectivity towards MAO-A and MAO-B. Molecular docking and dynamics simulations indicated that compound 3l inhibited the activity of LSD1 through multiple interactions. CONCLUSION The structures of α-naphthylthiol amino acid ester can serve as lead compounds or active fragments, laying a solid foundation for the subsequent design of LSD1 inhibitors based on structure-oriented drug design.
