ObjectiveTo develop a standardized classification model for traditional Chinese medicine （TCM） syndrome patterns of mixed hemorrhoids using multi-center real-world data， and unveil their distribution patterns and core risk factors， thereby providing evidence-based support for standardizing TCM syndrome differentiation and implementing precision interventions. MethodsA multi-center cross-sectional study was conducted， enrolling 13 283 mixed hemorrhoid patients from eight hospitals in Jiangsu Province between September 1st， 2023 and December 31st， 2024. DeepSeek-R1-Distill-Qwen-7B and LLaMA-3.3 large language models （LLM） were integrated with latent class analysis （LCA） to perform unsupervised learning and latent class modeling of TCM symptomatology. Potential risk factors were screened via univariate analysis， followed by logistic regression to identify independent risk factors for each syndrome pattern. ResultsThe model's performance indicators were stable and reliable across different clinical data types，i.e. in the outpatient records， past medical history （F1=99.7%）， current medical history （F1=94.9%）， and specialist examination （F1=90.7%）； in inpatient records， past medical history （F1=98.2%）， current medical history （F1=91.2%）， specialist examination （F1=90.3%）， and discharge status （F1=90.6%）. Latent class mode-ling identified four core TCM syndrome patterns including spleen deficiency and qi sinking syndrome （915 cases， 6.89%）， damp-heat pouring downward syndrome （10 820 cases， 81.46%）， qi stagnation and blood stasis syndrome （1252 cases， 9.43%）， and wind injuring intestinal collaterals syndrome （296 cases， 2.22%）， with respective latent class probabilities of 0.069， 0.815， 0.094， and 0.022. Logistic regression demonstrated that gender， age， disease duration， hypertension， diabetes， hyperlipidemia， constipation， smoking history， and alcohol consumption were independent risk factors for pattern differentiation （P＜0.05）. The efficacy validation evaluation revealed that the cure rates for patients with spleen deficiency and qi sinking syndrome and qi stagnation and blood stasis syndrome were higher than those for patients with damp-heat pouring downward syndrome （adjusted P＜0.05）， with no statistically significant differences among other syndrome patterns. ConclusionDamp-heat pouring downward syndrome is the predominant syndrome in mixed hemorrhoids. Gender， age， disease duration， hypertension， diabetes， hyperlipi-demia， constipation， smoking history， and alcohol consumption are independent risk factors for the differentiation of syndrome types.

This paper has constructed a traditional Chinese medicine （TCM） specialized disease dataset platform for mixed hemorrhoids based on a multimodal large model， and the preliminary application has been validated. The platform uses StarRocks to establish a four-level data warehouse system， enabling the aggregation， cleaning， and standardization of multi-source heterogeneous data. Using DeepSeek-R1-Distill-Qwen-7B as the base model， domain fine-tuning is performed through low-rank adaptation （LoRA） technology. Combined with LLaMA-3.3 natural language processing and reasoning chain techniques， the platform enables intelligent parsing and structured extraction of unstructured TCM medical records. It accurately identifies six major categories and 28 subcategories of entities， including symptoms and syndromes， with a fine-tuned model F1 score of 93.8%. The platform has established a high-quality specialized disease dataset containing more than 50,000 medical records and has been applied in a real-world study involving 17,831 patients， preliminarily verifying the efficacy of TCM heritage surgery.

Objective: To investigate the association of special family structure and physical activity with psychological sub health among secondary vocational school students, so as to provide reference to inform mental health promotion in the population. Methods: From September to December 2024, a convenience sample was drawn from 16 schools including 5 141 secondary vocational school students across 8 provinces (municipalities) in China (Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai, Zhejiang). A self developed questionnaire, Multidimensional Sub health Questionnaire of Adolescents and International Physical Activity Questionnaire Short Form were used to investigate and evaluate basic information, family structure, psychological sub health status and physical activity. Descriptive statistics and Logistic regression analysis were performed to explore relationships of special family structures and physical activity with psychological sub health in secondary vocational school students. Results: The detection rate of psychological sub health among secondary vocational school students was 11.0%. The reporting rates for secondary vocational school students who lost their father or lost their mother, whose parents divorced, whose parents remarried, and those from special family structures were 2.8%, 0.8%, 11.8%, 3.9%, and 14.7%, respectively. Moreover, the detection rates of psychological sub health and its sub dimensions significantly differed among secondary vocational school students grouped by family type (divorced parental families, remarried parental families and special family structures)( χ 2=5.90-22.67, all P <0.05). Binary Logistic regression indicated that maternal bereavement was associated with a higher risk of conduct problems [ AOR ( 95% CI )= 2.90(1.15-7.33)], and parental divorce was associated with a higher risk of psychological sub health ( AOR= 2.71 , 95%CI =1.04- 7.06 ) among secondary vocational school students (both P <0.05). Interaction analysis showed that both students with a special family structure and insufficient physical activity [ AOR (95% CI )=1.99(1.44-2.75)] and those with a non-special family structure and insufficient physical activity [ AOR (95% CI )=1.81(1.48-2.22)] were associated with increased risks of psychological sub health among secondary vocational school students (both P <0.01). Conclusion Special family structure and physical activity are associated with psychological sub health among secondary vocational school students; early identification and assessment based interventions for those with a special family structure should be strengthened, while school based physical activity should be implemented to increase physical activity levels,thereby reducing the risk of psychological sub health.

Objective: To examine the prevalence of e-cigarette use and associated factors among primary and secondary school students in Pudong New Area, Shanghai, and to explore the pathways linking harm perception of e-cigarettes, interpersonal social influence, and attitudes toward e-cigarette use with experimentation behavior, in order to provide scientific basis for further optimizing the prevention and control strategies of e-cigarette among adolescents. Methods: From September to October 2025, a multi stage cluster random sampling method was used to select 5 144 primary and secondary school students aged 8-19 years from 47 primary and secondary schools in Pudong New Area, Shanghai, to conduct an anonymous questionnaire survey. The questionnaire collected information on e-cigarette use, harm perception of e-cigarette, interpersonal social influence, and attitudes toward e-cigarette use. The Chi-square test was applied to analyze the differences in cigarette and e-cigarette use behavior among primary and secondary school students with different demographic characteristics. Structural equation modeling (SEM) was constructed using Mplus 8.3 software, and the bootstrap method was utilized to test the mediating effects. Results: The reported rates of cigarette experimentation, e-cigarette experimentation, and current e-cigarette use among primary and secondary school students were 1.85%, 2.10%, and 0.70%, respectively. Higher reporting rates of e-cigarette experimentation were observed among boys (2.82%), secondary school students aged 16-19 (3.39%), senior high school students (3.05%), and those with weekly pocket money >100 yuan ( 6.11% ) ( χ 2=11.67, 8.61, 8.00, 54.18, all P <0.05). Structural pathway analysis results demonstrated that e-cigarette harm perception positively predicted interpersonal social influence ( β =0.61) and e-cigarette use attitude ( β = 0.53 ), and interpersonal social influence ( β =0.65) and e-cigarette use attitude ( β =0.25) further promoted e-cigarette experimentation behavior among primary and secondary school students (all P <0.01), with interpersonal social influence playing a major mediating role (indirect effect=0.40). Conclusions E-cigarette experimentation behavior among primary and secondary school students in Pudong New Area is jointly influenced by multiple psychosocial factors. Intervention strategies should strengthen interpersonal social factors such as family and peers on the basis of health education, thereby constructing a comprehensive prevention and control strategy for e-cigarette use among primary and secondary school students.

Sensorineural hearing loss is one of the most common sensory disorders. In recent years, auditory neuropathy spectrum disorders caused by mutations in the OTOF gene have garnered significant attention worldwide, marking it as the first deafness gene with breakthroughs in gene therapy. Most patients with OTOF gene mutations present with stable, congenital, or prelingual onset of hearing loss, which can range from severe to profound and even complete hearing loss. However, a minority of patients may exhibit mild to moderate progressive hearing loss or temperature-sensitive hearing loss. This review further explores the genotype-phenotype relationship of the OTOF gene based on reported cases in China and abroad. Additionally, we analyze the characteristics of the natural history of OTOF gene mutations within the Chinese population. This study aims to provide a reference for the clinical diagnosis, evaluation, and treatment of hearing loss associated with OTOF gene mutations.

Detrusor-sphincter dyssynergia (DSD) is a lower urinary tract dysfunction syndrome caused by disorders of the neural regulatory pathways for micturition. Its core feature is that the urethral sphincter fails to relax coordinately during detrusor contraction; instead, the persistent abnormal contraction leads to a series of severe complications such as dysuria, elevated intravesical pressure, and upper urinary tract damage.DSD is common in patients with central nervous system lesions, such as spinal cord injury and multiple sclerosis. This paper systematically reviews the latest research progress on the neural mechanisms of DSD, including ① loss of central regulation and excessive excitation of the spinal cord center, i.e., the loss of supraspinal inhibition leading to sacral spinal reflex hyperactivity; ② imbalance of key neurotransmitters and receptors, involving excessive glutamatergic excitation, weakened gamma-aminobutyric acid ergic/glycinergic inhibition, and the involvement of purinergic and endocannabinoid systems; ③ neuroimmunity and inflammatory response, where the activation of microglia and astrocytes after spinal cord injury releases pro-inflammatory factors, exacerbating neuronal excitability and circuit remodeling; ④ peripheral nerve and gut-bladder axis mechanisms, where sphincter structural remodeling and the gut microbiota-neuroimmunity crosstalk form a vicious cycle. The paper focuses on the sacral Onuf's nucleus as the“core hub”and key therapeutic target of DSD, discussing the central role of its dysfunction in the occurrence of synergistic disorders. In terms of therapeutic strategies, the paper summarizes existing traditional methods, such as drugs, botulinum toxin injection and neuromodulation, and envisions the cutting-edge directions of targeted intervention, such as precise strategies including gene therapy and neurotrophic support, as well as the challenges faced in clinical translation. Finally, the paper discusses the application prospects of precision medicine and artificial intelligence in the diagnosis and treatment of DSD, including precise classification based on multi-omics data, artificial intelligence-assisted recommendation of individualized treatment plans, and the development of dynamic closed-loop regulation systems. This paper aims to provide a theoretical basis and research direction for in-depth understanding of the neural mechanisms of DSD, and to promote the precise diagnosis, treatment and neural function remodeling.

Objective To explore the real experiences of nutrition impact symptoms in esophageal cancer patients during diagnosis and treatment,and to provide references for developing nutritional management strategies.Methods Using purposive sampling,15 esophageal cancer patients admitted to the thoracic surgery department of a tertiary grade A hospital in Guangzhou from October to December 2024 were selected for semi-structured interviews.Thematic analysis was used for data analysis.Results 4 themes and 12 sub-themes were identified:①Multiple symptom perceptions:esophageal obstruction-dysphagia,appetite-affecting symptoms,multiple symptom over-lap,and individual differences in symptom perception.② Insufficient symptom cognition:overestimation of symptom controllability and biased symptom attribution.③ Negative emotional reactions:anxiety and fear about eating,frustration with declining eating function,and helplessness and guilt about losing control over eating.④ Di-verse symptom coping strategies:avoidance coping,adaptive coping,and active nutritional management.Conclusion The nutrition impact symptom experiences of esophageal cancer patients are complex and diverse.Healthcare professionals should promptly identify and assess nutrition impact symptoms,provide nutrition health education,strengthen psychological guidance,and develop culturally distinctive individualized nutritional management strategies.

Objective:To assess the trends in the burden of periodontal disease among individuals aged 60 years and above in China from 1990 to 2021, thereby providing a scientific foundation for the development of targeted prevention and control strategies for periodontal disease in the elderly.Methods:Utilizing data from the Global Burden of Disease Study 2021 (GBD 2021), key indicators including incidence, prevalence, and disability-adjusted life years (DALY) rates were analyzed. Age-standardized rates were determined using the global standard population. Trends in the disease burden of periodontal disease among the elderly population in China from 1990 to 2021 were analyzed using Joinpoint regression analysis, and an autoregressive integrated moving average (ARIMA) model was applied to forecast the disease burden from 2022 to 2036.Results:The annual average percentage changes (AAPC) in the number of incident cases, prevalent cases, and DALYs due to periodontal disease among individuals aged 60 years and above in China from 1990 to 2021 were 3.215% (95% CI: 3.149%-3.281%, P<0.05), 3.161% (95% CI:3.037%-3.286%, P<0.05), and 3.091%(95% CI: 2.887%-3.296%, P<0.05), respectively. The results indicated that the average annual change trends of the number of incident cases, number of prevalent cases, and number of DALYs were real upward trends. Compared with other age groups, the number of incident cases, prevalent cases, and DALYs were the highest among the population aged 60-69 years. The AAPC for age-standardized incidence rate, prevalence, and DALY rates were -0.012% (95% CI:-0.031%-0.008%, P>0.05), 0.023% (95% CI:-0.070%-0.116%, P>0.05), and 0.013% (95% CI:-0.089%-0.115%, P>0.05), respectively. This indicated that the average annual change trends of the age-standardized incidence rate, age-standardized prevalence rate, and age-standardized DALY rate might be caused by random fluctuations. Males exhibited higher prevalence and DALY rates than females across all age groups ( P<0.05), whereas the incidence rates showed minimal differences between males and females across all age groups. The ARIMA forecast model indicated that the age-standardized incidence rate among males in the elderly population in China was relatively stable, while that among females showed a downward trend; the age-standardized prevalence and DALY rates followed a pattern of "decline-rise-decline". Conclusions:The disease burden of periodontal disease among Chinese adults aged 60 and above showed an overall upward trend from 1990 to 2021, with males and individuals aged 60-69 identified as high-risk groups. With the exacerbation of aging, the prevention and control situation remains severe, necessitating the implementation of gender-differentiated interventions to reduce the disease burden.

Objective To identify the hub gene of fibroblast-like synoviocytes in rheumatoid arthritis(RA)and verify its impact on proliferation,migration and invasion of the cells.Methods Four independent synovial tissue microarray transcriptome sequencing datasets and one single cell sequencing dataset were downloaded from the Gene Expression Omnibus(GEO)database,and the hub gene of RA fibroblast-like synovial cells was identified by differential gene analysis,weighted gene co-expression network analysis(WGCNA)and single-cell sequencing data analysis.The expression of TNFAIP6 in human RA fibroblast-like synovial cell line MH7A was detected by RT-qPCR and Western blotting under simulated inflammatory environment.After MH7A cells were transfected with si-TNFAIP6,CCK-8 and Transwell assays were applied to detect the effects of silencing TNFAIP6 on the proliferation,migration and invasion abilities of MH7A cells.Results With the aid of differential gene expression analysis,WGCNA,and single-cell sequencing data,we identified TNFAIP6 as the characteristic gene of RA fibroblast-like synoviocytes.RT-qPCR and Western blot assay demonstrated that TNFAIP6 was significantly highly expressed at mRNA and protein levels in MH7A cells stimulated with 10 ng/mL TNF-α when compared to the cells treated with PBS(P＜0.05).CCK-8 and Transwell assays indicated that the silencing of TNFAIP6 markedly inhibited the proliferation,migration and invasion abilities of MH7A cells when compared with the control cells(FAM-si-NC,P＜0.05).Conclusion TNFAIP6 is highly expressed specifically in RA fibroblast synoviocytes,which promotes the proliferation,migration and invasion,and may be the main contributor to the abnormal activation of RA fibroblast synoviocytes.
