Objective:
To explore the association between nap duration with anxiety and depressive symptoms among junior high school students, in order to provide evidence for mental health interventions for adolescents.
Methods:
From May to June 2022, a combination of convenience sampling and cluster sampling was used to select 2 491 students from 2 junior high schools in Haizhu District, Guangzhou City for questionnaire survey and physical examination. The questionnaire collected nap duration, night time sleep duration, bedtime, physical activity, and sedentary behavior. Anxiety and depressive symptoms were assessed using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7), respectively. Log-binomial regression model was used to analyze the association of nap duration with anxiety and depressive symptoms, as well as comorbidity among junior high school students, and a restricted cubic spline (RCS) Log-binomial regression model was employed to analyze the non linear relationship after adjusting for covariates.
Results:
The detection rates of anxiety symptoms, depressive symptoms and comorbidity among junior high school students were 13.29%,14.65%,9.19%. After adjusting for covariates such as age, gender and nighttime sleep duration, compared with a school day nap duration of <30 min/d, a nap duration of 30-<60 min/d was associated with a reduced risk of anxiety symptoms ( APR =0.68, 95% CI =0.49-0.98) and comorbidity ( APR =0.56, 95% CI =0.39-0.87)(both P < 0.05 ). Compared with no napping on weekends, a nap duration of 30-<60 min/d was associated with a reduced risk of anxiety symptoms ( APR =0.62, 95% CI =0.41-0.88), depressive symptoms ( APR =0.52, 95% CI =0.34-0.75) and comorbidity ( APR = 0.52 , 95% CI =0.30-0.83)(all P <0.05). RCS curves showed a nonlinear relationship between weekend nap duration and the prevalence of anxiety, depressive symptoms and comorbidity among junior high school students(all P non linear <0.05); weekend nap duration of <120 min was associated with a lower risk of anxiety and depressive symptoms, and weekend nap duration of >180 min was associated with an increased risk.
Conclusions
Appropriate nap duration can help reduce the risk of anxiety, depressive symptoms, and the comorbidity among junior high school students. Adolescents should be guided to reasonably arrange nap duration for promoting physical and mental health.

Histone lactylation is a recently identified post-translational modification, wherein lactate mediates the enzymatic addition of lactyl groups to lysine residues on histones. Since its discovery, extensive research has demonstrated that histone lactylation is widely present in human tissues and plays a pivotal role in regulating the transcription of specific genes. Subsequent studies have further established this modification as a widespread epigenetic mark with significant physiological implications. With advancing research, accumulating evidence confirms that lactylation at distinct histone sites elicits diverse biological effects—such as promoting cell proliferation, driving inflammatory responses, and enhancing fibrosis—all of which profoundly influence disease progression and serve as key drivers of disease onset and development. Conversely, inhibiting histone lactylation can alter disease outcomes, positioning histone lactylation as a promising therapeutic target. Moreover, studies have revealed crosstalk between histone lactylation and other post-translational modifications, such as acetylation and methylation, which collectively regulate disease progression. Notably, lactylation occurs not only on histones but also on non-histone proteins. Histone lactylation activates specific gene transcription and reshapes metabolic epigenetics, while non-histone lactylation directly modulates enzyme activity, signal transduction, and protein stability. These two facets form a synergistic network through shared lactate pools, common modifying enzyme systems, and pathway crosstalk, thereby constructing a multi-dimensional regulatory framework—namely, the “histone lactylation-metabolism hub-non-histone lactylation” axis. This architecture bridges metabolism and epigenetics, and deciphering its topological structure may provide novel targets for precise intervention in diseases driven by lactate-mediated signaling hijacking. Traditional Chinese medicine (TCM), grounded in clinical practice, has been shown to regulate histone lactylation by modulating lactate metabolism and lactylation-related enzymes, thereby influencing disease progression. Moreover, certain TCM formulations exhibit potential as alternative therapies for drug-resistant diseases, underscoring the significance of further exploring TCM-mediated regulation of histone lactylation in future therapeutic strategies. This review aims to elucidate the mechanisms underlying histone lactylation, systematically delineate the associations between site-specific histone lactylation and various diseases, present a comprehensive landscape of the “lactate-histone lactylation and functional protein lactylation” axis, and summarize the mechanistic basis and research advances in TCM-mediated regulation of histone lactylation for disease treatment. Additionally, we discuss current challenges in histone lactylation research and propose future directions, ultimately aiming to deepen understanding and broaden perspectives on the roles and therapeutic potential of histone lactylation in disease.

Clinical and Molecular Hepatology 2026;32(2):843-865
Background/Aims:
Cholangiocarcinoma (CCA) is a primary malignant neoplasm with an extremely poor prognosis. While combined chemoradiotherapy has been demonstrated to delay CCA progression to a certain extent, the absence of specific molecular biomarkers or targets significantly hinders the diagnosis and treatment of CCA.
Methods:
Through cross-analysis of proteomics and ADMA modificationomics, we identified DDX1 overexpressed in CCA with elevated R602-ADMA modifications. HPLC-MS/MS identified PRMT1 as the methyltransferase and USP10 as the deubiquitinating enzyme for DDX1. Immunofluorescence and nuclear-cytoplasmic partitioning experiments confirmed DDX1’s nuclear localization. GO and KEGG analyses clarify the biological functions of DDX1 in response to hypoxia. RNA-seq transcriptomics analyzed key pathways influenced by DDX1. A hydrodynamic in situ CCA mouse model was established to validate the chemopreventive effects of the PRMT1-specific inhibitor GSK715 on CCA development.
Results:
DDX1 promotes CCA progression both in vivo and in vitro and can be inhibited by GSK715. Mechanistically, PRMT1 mediates ADMA modification at position R602 of DDX1. This modification promotes DDX1 nuclear localization by recruiting USP10 to deubiquitinate DDX1, while simultaneously inhibiting PRMT1 degradation. DDX1 promotes the transcription of PRMT1 and USP10 by binding to the mRNA 3’UTR region, establishing a positive feedback regulatory pathway. This mechanism promotes the occurrence and development of CCA and can serve as a target for the inhibitor GSK715 to suppress CCA progression.
Conclusions
Our study identified DDX1-R602-ADMA modification as a novel ADMA modification in CCA. It further confirmed its pivotal role in CCA progression. Targeting the USP10-PRMT1-DDX1 axis may represent a significant therapeutic approach for CCA.

Colorectal cancer (CRC) is characterized by persistently high incidence and mortality. Current therapies are limited by drug resistance and modest patient benefit, underscoring the urgent need for new perspectives rooted in tumor biology. The unique metabolic landscape of CRC makes it an ideal model in which to dissect the pathological roles of lactylation regulatory networks: microsatellite-stable (MSS) CRC, which accounts for approximately 85% of cases, concurrently upregulates glycolysis and oxidative phosphorylation, engaging in intense metabolic competition with immune cells; the intratumoral lactate pool exhibits a distinctive “dual-source supply” feature—in addition to tumor-intrinsic glycolysis, substantial exogenous lactate is provided by gut microbiota dysbiosis and by colonizing bacteria within liver metastases; high-frequency oncogenic mutations and lactylation modifications establish a feed-forward circuit of “oncogene-driven lactate accumulation-lactylation-facilitated tumor progression”. Moreover, MSS CRC displays near-complete unresponsiveness to immune checkpoint inhibitors, a phenomenon underpinned by multiple immune evasion mechanisms mediated by lactate and lactylation. Lactate metabolism is a hallmark of metabolic reprogramming in cancer. Lactate homeostasis provides tumor cells with metabolic substrates, modulates redox status, and regulates fatty acid metabolism to promote malignant progression. Notably, lactate can drive lactylation—an emerging post-translational modification (PTM) in which lactyl groups are attached to lysine residues, dynamically governing gene transcription and protein function and thereby establishing a bridge between metabolism and epigenetics. Lactate and lactylation form a multidimensional, coordinated network: lactylation of key metabolic enzymes such as LDHA reinforces a positive feedback loop that sustains lactate production; lactylation of upstream transcription factors such as HIF-1α drives metabolic reprogramming; furthermore, lactylation engages in crosstalk with m6A and m5C RNA modifications as well as with other PTMs such as acetylation, profoundly reshaping cellular behavior. In CRC, histone lactylation drives malignant phenotypes by activating immunosuppressive programs, inhibiting ferroptosis, and promoting invasion and migration; non-histone lactylation accelerates translation elongation, stabilizes β‑catenin, maintains redox homeostasis, and prevents PD-L1 degradation, thereby facilitating tumor progression. Lactylation-related gene signatures have demonstrated potential for prognostic stratification. Therapeutic strategies targeting the lactylation network range from upstream metabolic intervention to modulation of the modifying enzymes and direct blockade of lactylation modifications, forming a hierarchical interventional framework. However, current evidence derives predominantly from cell lines and xenograft models, and a causal relationship between lactylation and malignant progression in CRC has yet to be rigorously established. Whether inhibition of lactylation can alter CRC phenotypes independently of metabolic alterations and acetylation fluctuations remains a central unanswered question in the field. This review systematically examines the research progress and translational challenges surrounding lactylation regulatory networks, aiming to provide a circumspect assessment to inform the development of novel therapeutic strategies for CRC.

Objective: This study employed next-generation sequencing (NGS) for large-scale genotyping of 42 blood group systems in blood donors to evaluate its applicability in multi-system blood group identification and rare blood type repository construction, while exploring the complementary value of third-generation sequencing (TGS) in haplotype phasing and variant capture in regions with insufficient sequencing depth for ABO ambiguous samples. Methods: A total of 562 regular blood donors (median donation frequency 11 times) from a blood center were enrolled. NGS was used for genotyping of 42 blood group systems, with a focused analysis on 12 systems essential for rare blood type repository construction: MNS, Lutheran, Kell, Duffy, Kidd, Diego, Yt, Colton, Gerbich, Ok, H, and I. TGS was employed to resolve haplotype phasing (i. e., determining whether different mutation sites are located on the same chromosome) in 12 ABO samples with discrepancies between forward and reverse typing. Serological and genotyping results were compared for MNS, Duffy, Kidd, Lewis, and ABO systems. Results: NGS-based genotyping revealed that Fy (a-b+) in the Duffy system accounted for 0.87% (4/458), and Di (a+b+) in the Diego system accounted for 10.62% (31/292). The Lutheran, Kell, Yt, Colton, H, Ok, I, and Gerbich systems exhibited near-uniform phenotype distributions. Among the 12 ABO ambiguous samples, NGS yielded multiple possible genotype combinations in 5 cases due to inability to phase alleles, whereas TGS uniquely resolved the genotypes through long-read sequencing. In one case, NGS detected only 2 mutation sites due to insufficient sequencing depth, while TGS identified all 11 sites and assigned the A1 phenotype. Concordance rates between serology and genotyping were: Duffy 96.55% (140/145), ABO 96.43% (513/532), Kidd 94.17% (97/103), MNS 85.07% (57/67), and Lewis 68.18% (75/110). In the MNS system, 7 of 8 samples serologically typed as M+N+ but genotyped as M-N+ carried GYPB variants. Lewis discrepancies predominantly featured genotype Le (a-b+) with serological phenotypes of Le (a+b-), Le (a+b+), or Le (a-b-). The NGS platform completed sequencing of 192 samples within 2 weeks. Conclusion: The tiered genotyping strategy combining NGS, TGS, and serology enables multi-system blood group identification in large-scale blood donor populations. TGS provides complementary value in phasing ambiguous ABO samples and detecting variants in regions with insufficient sequencing depth. This study provides a technical framework and baseline frequency data for the expansion of a local rare blood type repository. However, standardization and cost-effectiveness of this strategy require further validation with expanded sample sizes, and serological confirmation should be retained for secretion status-related systems such as Lewis.

Objective To investigate the acceptance and satisfaction of tuberculosis prevention and control personnel in Beijing with the patient management system, and to provide a basis for further improving the patient management model. Methods A survey was conducted on the current usage, satisfaction, willingness to use and system improvement opinions of the patient management system among medical staff involved in the supervision and medication management of pulmonary tuberculosis patients in Beijing. Results A total of 360 medical staff participated in the survey. “Patient management” was the function with the largest number of users, accounting for 96.94%. The proportion of users of each module who believed that the module's design met actual work needs was over 90%. About 94.44% of respondents believed that patient management systems facilitated the transfer and sharing of information between institutions. And 90.83% of respondents thought that the patient management system was easy to operate, and 89.17% of respondents believed that patient management systems reduced workload. About 97.50% of respondents were satisfied with the overall use of the patient management system. The results of the influencing factor analysis showed that those with 3 or less modules designed to meet actual work were less satisfied than those with more than 3 modules, and the difference was statistically significant (P=0.001). Respondents put forward suggestions for improvement on the optimization of operational details such as system response speed, interface design, system login and query statistics. Conclusion Medical staff involved in the follow-up management of pulmonary tuberculosis patients are highly satisfied with their work using the patient management system. During the promotion and use, it is still necessary to continuously optimize the system functions according to work needs so that the system can truly facilitate work.

Objective:To analyze the efficacy and safety of splenic artery occlusion combined with microwave ablation (MWA) in the treatment of hepatocellular carcinoma (HCC) complicated with liver cirrhosis and hypersplenism.Methods:Clinical data of 24 patients with HCC complicated with cirrhosis and secondary hypersplenism admitted to Airport Hospital of Tianjin Cancer Hospital from August 2023 to May 2024 were retrospectively analyzed, including 13 males and 11 females, aged (57.4±7.8) years. All patients were treated with splenic artery occlusion combined with MWA of spleen. Spleen volume measured by MRI before and after MWA, blood routine changes and postoperative complications (fever, bleeding, pain, renal failure and thrombosis) were analyzed.Results:The splenic volume of 24 patients measured by MRI before MWA was 692.4 (504.7, 1023.7) cm 3, and decreased to 225.0 (186.4, 285.6) cm 3 after treatment for 60 days ( Z=-3.23, P=0.001). The red blood cell counts were comparable before and after microwave ablation. The white blood cell count before MWA was 4.3 (3.2, 5.3)×10 9/L, which increased to 11.0 (8.6, 15.8)×10 9/L three days after treatment, and to 5.0 (3.3, 6.1)×10 9/L 90 days after treatment ( Z=-4.70, -0.34, P<0.001, P=0.732). The platelet count of the patients was 47.0 (39.0, 67.0)×10 9/L before MWA, which increased to 155.0 (120.3, 214.3)×10 9/L seven days after Treatment, and to 77.0 (63.0, 125.0)×10 9/L 90 days after treatment ( Z=-5.29, -2.51, P<0.001, P=0.012). None of the patients had obvious bleeding and no death occured. One patient (4.2%) developed renal failure, one patient (4.2%) had splenic venous thrombosis, 4 patients (16.7%) had pain of different degrees, and 5 patients (20.8%) had low fever. Conclusion:Splenic artery occlusion combined with MWA in the treatment of HCC complicated with liver cirrhosis and hypersplenism can significantly reduce spleen volume and increase platelet level with acceptable complications.
