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.

BackgroundNon-suicidal self-injury （NSSI） behaviors are common among adolescents with depressive disorders， and school bullying is recognized as a major risk factor. Previous research has shown that self-esteem and alexithymia are closely associated with both school bullying and NSSI. However， the mediating roles of self-esteem and alexithymia in the link between school bullying and NSSI are unclear. ObjectiveTo explore the mediating roles of alexithymia and self-esteem in the relationship between school bullying and NSSI behaviors in adolescents with depressive disorders， in order to inform intervention strategies targeting NSSI in this population. MethodsA total of 335 adolescents diagnosed with depressive disorders and treated at the First Psychiatric Hospital of Harbin from July 2023 to October 2024 were enrolled. Assessments included a self-developed demographic questionnaire， Adolescent Non-suicidal Self-injury Assessment Questionnaire-Behavior （ANSAQ-B）， Delaware Bullying Victimization Scale-Student （DBVS-S）， Rosenberg Self-Esteem Scale （RSES）， and 26-item Toronto Alexithymia Scale （TAS-26）. Pearson correlation analysis was used to examine the relationship among variables. Controlling for gender and age at onset of depressive symptoms， mediation analysis was performed using the “mediation” package in R 4.4.2. ResultsScores on DBVS-S and TAS-26 were positively correlated with ANSAQ-B score （r=0.408， 0.417， P<0.01）， while RSES scores were negatively correlated（r=-0.300， P<0.01）. Regression analysis showed that school bullying and alexithymia significantly positively predicted NSSI behaviors （B=0.212， 0.333， P<0.01）， while self-esteem negatively predicted NSSI behaviors （B=-0.368， P<0.01）. Alexithymia was found to mediate the relationship between school bullying and NSSI behaviors， with an indirect effect of 0.040 （95% CI： 0.018~0.069） ，account for 17.17% of the total effect. The indirect effect through self-esteem was not statistically significant （95% CI： -0.004~0.069）. ConclusionExposure to school bullying and high levels of alexithymia are important predictors of NSSI behavior in adolescents with depressive disorders， and school bullying may indirectly influence NSSI behavior through alexithymia. ［Funded by Scientific Research Project of Health Commition of Heilongjiang Province，（number， 20230303090154］

Objective:To observe the effects of shoulder-three-needle therapy plus joint mobilization and extracorporeal shock wave therapy(ESWT)in improving symptoms and pain mediators in patients with scapulohumeral periarthritis.Methods:A total of 82 patients with scapulohumeral periarthritis were randomized into a control group and an observation group by the random number table method,with 41 cases in each group.The control group was treated with ESWT.The observation group was treated with additional shoulder-three-needle therapy plus joint mobilization based on the treatment in the control group.After 4 weeks of treatment,shoulder joint function,pain mediators,inflammatory factor levels,and clinical efficacy were compared between the two groups.Results:The total effective rate and the score of shoulder joint function in the observation group were higher than those in the control group(P<0.05).After treatment,the levels of serum pain mediators substance P(SP),5-hydroxytryptamine(5-HT),and prostaglandin E2(PGE2),as well as inflammatory factors interleukin(IL)-6,tumor necrosis factor(TNF)-α,and C-reactive protein(CRP)decreased significantly in both groups(P<0.05).And,the serum pain mediators SP,5-HT,and PGE2,and the levels of inflammatory factors IL-6,TNF-α,and CRP in the observation group were all lower than those in the control group(P<0.05).Conclusion:Shoulder-three-needle therapy plus joint mobilization and ESWT has a better curative effect than ESWT alone in treating scapulohumeral periarthritis.It can effectively improve the clinical symptoms,reduce the levels of pain mediators and inflammatory factors,and increase shoulder joint function.

Objective:To investigate the expression and clinical significance of the complement C3 and the S100 calcium binding protein A10 (S100A10) in children with traumatic brain injury (TBI).Methods:This case-control study included 129 TBI children admitted to the Affiliated Xuzhou Children′s Hospital of Xuzhou Medical University from January 2023 to November 2024.The patients were divided into a mild group (85 cases) and a moderate-to-severe group (44 cases).Thirty children with inguinal hernia but no underlying diseases admitted to the hospital during the same period were enrolled as the control group A. Twenty children whose lumbar puncture examination showed normal cerebrospinal fluid results and imaging tests showed no central nervous system disorder were included in the control group B. The children with moderate-to-severe TBI were followed up for 1 month after injury and further divided into good and poor prognosis groups.One-way (repeated-measures) analysis of variance (ANOVA) and t-tests were used to compare differences in complement C3 and S100A10 levels in serum and cerebrospinal fluid among groups.The correlation analysis was performed using the Spearman rank correlation method.Receiver operating characteristic (ROC) curves were drawn to evaluate the value of complements C3 and S100A10 proteins for predicting TBI severity. Results:The serum complement C3 levels in control group A, mild TBI, and moderate-to-severe TBI groups were (1.15±0.26) g/L, (1.02±0.09) g/L, (0.87±0.15) g/L, respectively.The difference in serum complement C3 levels was statistically significant among these three groups ( F=53.661, P<0.001).The serum S100A10 levels in control group A, mild TBI, and moderate-to-severe TBI groups were (0.09±0.03) μg/L, (0.17±0.04) μg/L, (0.32±0.11) μg/L, respectively.The difference in serum S100A10 levels was statistically significant among these three groups ( F=71.093, P<0.001).The levels of complement C3 and S100A10 in the cerebrospinal fluid (30 min post-operation) of children with severe TBI were significantly higher than those in the control group B, with statistically significant differences (all P<0.01).Correlation analysis revealed that Glasgow Coma Scale scores showed a positive correlation with serum complement C3 levels and a negative correlation with S100A10 levels ( r=0.592, -0.705; all P<0.001).The serum complement C3 and S100A10 levels were (0.90±0.13) g/L and (0.30±0.10) μg/L in the good prognosis group, and (0.74±0.16) g/L and (0.42±0.11) μg/L in the poor prognosis group, respectively.Both serum complement C3 and S100A10 levels were statistically significantly different between good and poor prognosis groups ( t=3.025, -3.014; all P<0.01).The complement C3 level in the cerebrospinal fluid of severe TBI children was (0.093±0.007) g/L 30 min after operation, and it gradually increased to reach the first peak at day 3 and the second peak at day 5 postoperatively[(0.112±0.005) g/L and (0.120±0.010) g/L, respectively].The difference in the complement C3 level in the cerebrospinal fluid of severe TBI children was significant between 30 min and 3-5 d after operation ( F=42.756, P<0.01).The S100A10 level in the cerebrospinal fluid of severe TBI children was (2.56±0.31) μg/L 30 min after operation, and then it showed a sustained increase, reaching (4.09±0.13) μg/L at day 7 postoperatively.The difference in the S100A10 level in the cerebrospinal fluid of severe TBI children was significant between 30 min and 7 d after operation ( F=110.676, P<0.01).ROC curve analysis showed that the areas under the curve for predicting moderate-to-severe TBI based on serum complement C3 and S100A10 levels were 0.802 and 0.889, respectively (all P<0.01). Conclusions:Serum complement C3 levels are significantly decreased whereas serum S100A10 levels are markedly elevated in pediatric TBI patients.The measurement of serum complement C3 and S100A10 levels can aid in the clinical assessment of the severity and prognosis of TBI children.Both complement C3 and S100A10 levels in cerebrospinal fluid show a significant elevation within 7 days after operation in severe pediatric TBI, which is potentially linked to sustained astrocyte activation.

Objective:To explore the application effects of the solution-focused approach combined with empathic nursing in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) .Methods:A total of 96 AMI patients who underwent PCI in the Department of Cardiology at Cangzhou Central Hospital from March 2020 to March 2023 were selected using convenience sampling. They were randomly assigned to an experimental group ( n=48) and a control group ( n=48) using a random number table. The control group received routine nursing care, while the experimental group received a solution-focused approach combined with empathic nursing. Medication adherence, coping strategies, and patient satisfaction were compared between the two groups. Results:After the intervention, medication adherence and satisfaction scores in the experimental group were significantly higher than those in the control group, and the differences werestatistically significant ( P<0.05) . Additionally, the experimental group scored higher in confrontation coping, and lower in avoidance and resignation coping than the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The combination of a solution-focused approach and empathic nursing can effectively improve medication adherence, coping strategies, and patient satisfaction in AMI patients after PCI.

Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.
