Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Objective: To systematically characterize the developmental trajectory and interdisciplinary integration of intelligent diagnosis in traditional Chinese medicine (TCM) through quantitative topic evolution analysis, we addressed the fragmentation of existing research and clarified the long-term research structure and evolutionary patterns of the field. Methods: A topic evolution analysis was performed on Chinese-language literature pertaining to intelligent diagnosis in TCM. Publications were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, and China Science and Technology Journal Database (VIP), covering the period from database inception to July 3, 2025. A hybrid segmentation approach, based on cumulative publication growth trends and inflection point detection, was applied to divide the research timeline into distinct stages. Subsequently, the latent Dirichlet allocation (LDA) model was used to extract research topics, followed by alignment and evolutionary analysis of topics across different stages. Results: A total of 3 919 publications published between 2003 and 2025 were included, and the research trajectory was divided into five stages based on data-driven breakpoint detection. The field exhibited a clear evolutionary shift from early rule-based systems and tongue-pulse image and signal analysis (2006 – 2010), to machine-learning-based syndrome and prescription modeling (2011 – 2015), followed by deep-learning-driven pattern recognition and formula association (2016 – 2020). Since 2021, research has increasingly emphasized knowledge-graph construction, multimodal integration, and intelligent clinical decision-support systems, with recent studies (2024 – 2025) showing the emergence of large language models and agent-based diagnostic frameworks. Topic evolution analysis further revealed sustained cross-stage continuity in syndrome modeling and prescription association analysis, alongside the progressive consolidation of integrated intelligent diagnostic platforms. Conclusion By identifying key technological transitions and persistent core research themes, our findings offer a structured reference framework for the design of intelligent diagnostic systems, the construction of knowledge-driven clinical decision-support tools, and the alignment of AI models with TCM diagnostic logic. Importantly, the stage-based evolutionary insights derived from this analysis can inform future methodological choices, improve model interpretability and clinical applicability, and support the translation of intelligent TCM diagnosis from experimental research to real-world clinical practice.

Juvenile dermatomyositis(JDM) is the most common idiopathic inflammatory myopathy in children, characterized by symmetric proximal muscle weakness and characteristic skin rashes, which may be accompanied by involvement of major organs. Aberrant upregulation of the interferon signaling pathway has been confirmed as the core pathological mechanism of JDM, and is closely associated with mitochondrial dysfunction, peripheral blood immune cell dysregulation, muscle damage and repair dysfunction, as well as cutaneous and pulmonary lesions. Interferon-related biomarkers and interferon scores can serve as evaluation indicators for disease activity. Type Ⅰ interferon inhibitors and Janus kinase inhibitors provide new therapeutic options for refractory JDM. This review systematically summarizes the role of the interferon signaling pathway in the pathogenesis of JDM and its potential therapeutic targets, aiming to provide references for the mechanistic research and precise treatment of JDM.

Objective: To investigate hepatocellular carcinoma ( HCC ) risk factors in hepatitis B e antigen (HBeAg)-negative cirrhotics , and to develop and validate a predictive model using these indicators . Methods: A total of 649 hospitalized patients with HBeAg-negative hepatitis B cirrhosis and HBeAg-negative primary HCC were enrolled . Patients were randomly divided into a modeling group (n = 298) and a validation group (n = 351) at a 7 ∶3 ratio . Logistic regression analysis was used to screen for independent predictors of HCC occurrence . A predic- tive model was constructed and validated using receiver operating characteristic ( ROC) curves . The clinical net benefit of the prediction model was assessed via decision curve analysis . Results: Univariate analysis showed sig- nificant statistical differences between the modeling and validation groups in serum alanine aminotransferase (ALT) , aspartate aminotransferase ( AST) , triglycerides ( TG) , gamma-glutamyl transferase ( GGT) , red blood cell count (RBC) , hemoglobin (Hb) , platelet count (PLT) , international normalized ratio (INR) , alpha-feto- protein (AFP) , serum calcium (Ca2 + ) , serum cholinesterase (CHE) , and HBV DNA levels . Multivariate logistic regression analysis identified AST , GGT , Hb , PLT , Ca2 + , CHE , and HBV DNA as independent influencing fac- tors for HCC occurrence (P < 0. 05) , with OR (95% CI) of 1 . 002 ( 1 . 000 - 1 . 005) , 1 . 006 ( 1 . 003 - 1 . 008) , 0. 994 (0. 988 - 0. 999) , 0. 984 (0. 981 - 0. 988) , 9. 624 (3 . 821 - 24. 245 ) , 0. 999 (0. 987 - 0. 999) , and 7. 530 (4. 143 - 13 . 687) , respectively. A nomogram prediction model was established based on these seven indi- cators . The area under the ROC curve was 0. 936 in the modeling group and 0. 941 in the validation group . Cali- bration curves demonstrated high predictive accuracy of the nomogram. Conclusion AST , GGT , Hb , PLT , Ca2 + , CHE , and HBV DNA are independent risk factors for HCC development in patients with HBeAg-negative hepatitis B-related cirrhosis . The established non-invasive prediction model exhibits good discriminative ability and clinical utility , providing an experimental basis for early detection and preventive screening of HCC in this patient population .

Objective:To evaluate the efficacy and safety of the pegaspargase, etoposide, methotrexate, and dexamethasone (PEMD) regimen in patients with early-stage nonupper respiratory digestive tract or advanced extranodal natural killer/T-cell lymphoma (ENKTL) .Methods:This retrospective analysis included 38 patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL who received PEMD regimen for induction chemotherapy at the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2022. Survival outcomes and prognostic factors were examined by Kaplan-Meier, and the Log-rank test was used to compare survival.Results:The study population had a median age of 48 years (range, 26-72 years) and included 30 males (78.9%) and 8 females (21.1%). 7 patients’ age >60 years (18.4%). The Eastern Cooperative Oncology Group (ECOG) performance score was >1 in 7 patients (18.4%) ; 20 patients (52.6%) had elevated lactate dehydrogenase levels; and 37 patients (97.4%) exhibited extranodal involvement. Using the Ann Arbor staging system, 37 patients (97.4%) were classified as stage Ⅲ-Ⅳ. The median number of treatment cycles was 5 (1-6), and the median follow-up duration was 60 months (24 - 101 months). Interim efficacy assessment revealed an overall response rate of 52.7%. At 2 and 4 years, the progression-free survival (PFS) rates were 34.2% (95% CI 22.0%-53.2%) and 25.5% (95% CI 14.7%-44.4%), respectively, and the overall survival rates were 50.0% (95% CI 36.4%-68.7%) and 45.5% (95% CI 31.4%-65.7%), respectively. The risk factors for worse PFS were ECOG performance score >1 [ HR=3.711 (95% CI 1.494-9.218), P=0.005]; bone marrow infiltration [ HR=2.251 (95% CI 1.026 - 4.938), P=0.043]; and Prognostic Index for Natural Killer/T-Cell Lymphoma score of 3 - 5 [ HR=2.350 (95% CI 1.009 - 5.476), P=0.048]. Multivariate analysis identified ECOG performance score >1 as an independent risk factor for PFS [ HR=7.971 (95% CI 2.222 - 28.591), P=0.001]. The main adverse effect was anemia in 31 patients (81.6%) . Conclusion:The PEMD regimen was safe and effective for patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL.

Cleidocranial dysplasia, a rare genetic disorder primarily caused by Runt-related transcription factor 2 (RUNX2) heterozygous mutation, serves as a representative model for investigating regulatory mechanisms of RUNX2 in bone remodeling and tooth eruption. As a master transcription factor governing mineralized tissue development, RUNX2 orchestrates bone remodeling and tooth eruption through diverse regulatory networks. It drives alveolar bone formation via transcriptional activation, integration of multiple signaling cascades, and epigenetic modifications, thereby generating the biomechanical force for tooth eruption. Concurrently, RUNX2 promotes osteoblastic secretion of osteoclastogenic factors and directly regulates osteoclast precursor differentiation, facilitating bone resorption at the coronal aspect of dental follicles to estavlish the eruption pathway. Furthermore, RUNX2 modulates eruption progression by participating in stress-induced biological signal transduction within dental follicle cells (DFCs), remodeling the DFCs microenvironment, and regulating DFCs senescence. RUNX2 also influences root development via the NOTUM-Wnt axis, providing auxiliary biomechanical conditions conducive to eruption. This review systematically delineates the pivotal role of RUNX2 in coordinating bone remodeling and tooth eruption. Future studies should leverage organoid models and multi-omics technologies to further elucidate the spatiotemporal regulatory networks of RUNX2, potentially advancing precision diagnostics and therapeutics for rare skeletal-dental developmental disorders.

Objective:To describe the prevalence of preserved ratio impaired spirometry (PRISm) in participants from the China Kadoorie Biobank (CKB) and explore the influencing factors.Methods:The CKB project conducted the baseline survey, the first and the second resurvey in 2004-2008, 2008, and 2013-2014, respectively. Based on the lung function tests, the participants were categorized into three groups: regular, PRISm, and airflow obstruction. The prevalence of PRISm was reported by gender, age, and region at the baseline survey. The secular trend in the prevalence of PRISm was described during the three surveys. Finally, we used the multiple logistic regression model to examine the factors related to PRISm in the baseline survey.Results:After standardization for gender, age, and region according to the sixth national census data in 2010, the overall prevalence of PRISm and airflow obstruction among the 434 760 participants at baseline was 24.8% and 6.1%, respectively. The prevalence of PRISm was higher in rural (25.4%) than that in urban areas (24.3%). Of the 10 study regions, Gansu had the highest prevalence of PRISm (56.0%), while Henan had the lowest (15.4%). After standardization for gender, age, and region according to the baseline population, the prevalence of PRISm decreased from 24.9% at baseline to 15.7% in the second resurvey, and the prevalence of airflow obstruction increased from 5.9% to 21.4%. Unmarried status, current smoking, using solid fuels for cooking, low body weight, being overweight, obesity, and central obesity were associated with an increased risk of PRISm. In contrast, higher education attainments, increased household income, and maintaining a specific degree of physical activity were associated with a reduced risk of PRISm.Conclusions:The prevalence of PRISm was high in adults aged 40 years and above in China, and it varied by sociodemographic and lifestyle factors.

Eosinophilic gastroenteritis(EG)is a rare disease characterized by abnormal infiltration of eosinophils(Eos)in gastrointestinal tissues.Due to the unclear pathogenesis of EG and the lack of effective therapeutic drugs,research on its novel mechanisms,targets and drugs is critical.This article starts by outlining the research progress in the pathogenesis of EG,involving IgE mediated typeⅠimmediate allergic reactions and T helper 2 cell(Th2)mediated delayed allergic reactions.Then,the related targets of EG are summarized,including Th2 cytokines and factors regulating Eos function,but there has been no breakthrough in the treatment of these targets.Finally,the therapeutic drugs for EG are reviewed,such as glucocorticoids,antiallergic drugs and biologics.The advantages and disadvantages of various drugs are also described.However,these drugs cannot meet the current demands of clinical treatment and there is an urgent need to develop novel therapeutic drugs.It is believed that multi-target therapy is an ideal treatment for EG,and that traditional Chinese medicine and natural products should be the priorities of research and development for EG therapeutic drugs in the future.This review is expected to provide new ideas for the clinical treatment strategies and drug development of EG.

[Objective] To explore the relationship between neutrophil activation under cardiopulmonary bypass (CPB) and the incidence of cardiac surgery-associated acute kidney injury (CS-AKI). [Methods] This prospective cohort study enrolled adult patients who scheduled for cardiac surgery under CPB at West China Hospital between May 1, 2022 and March 31, 2023. The primary outcome was acute kidney injury (AKI). Blood samples (5 mL) were obtained from the central vein before surgery, at rewarming, at the end of CPB, and 24 hours after surgery. Neutrophils were labeled with CD11b, CD54 and other markers. To assess the effect of neutrophils activation on AKI, propensity score matching (PSM) was employed to equilibrate covariates between the groups. [Results] A total of 120 patients included into the study, and 17 (14.2%) developed AKI. Both CD11b⁺ and CD54⁺ neutrophils significantly increased during the rewarming phase and the increases were kept until 24 hours after surgery. During rewarming, the numbers of CD11b⁺ neutrophils were significantly higher in AKI compared to non-AKI (4.71×10⁹/L vs 3.31×10⁹/L, Z=-2.14, P<0.05). Similarly, the CD54⁺ neutrophils counts were also significantly higher in AKI than in non-AKI before surgery (2.75×10⁹/L vs 1.79×10⁹/L, Z=-2.99, P<0.05), during rewarming (3.12×10⁹/L vs 1.62×10⁹/L, Z=-4.34, P<0.05), and at the end of CPB (4.28×10⁹/L vs 2.14×10⁹/L, Z=-3.91, P<0.05). An analysis of 32 matched patients (16 in each group) revealed that CD11b⁺ and CD54⁺ neutrophil levels of AKI were 1.74 folds (4.83×10⁹/L vs 2.77×10⁹/L, Z=-2.72, P<0.05) and 2.34 folds (3.32×10⁹/L vs 1.42×10⁹/L, Z=-4.12, P<0.05), respectively, of non-AKI at rewarming phase. [Conclusion] Neutrophils are activated during CPB, and they can be identified by CD11b/CD54 markers. The activated neutrophils of AKI patients are approximately 2 folds of non-AKI during the rewarming phase, with disparity reached peak between groups during rewarming. These findings suggest the removal of 50% of activated neutrophils during the rewarming phase may be effective to reduce the risk of AKI.
