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.

OBJECTIVE:
To evaluate the short-term effectiveness of Ilizarov technique combined with steel needle internal fixation in treating Charcot neuroarthropathy (CN) of the foot and ankle.
METHODS:
Between June 2020 and December 2023, 12 patients with Eichenholtz stage Ⅲ CN of the foot and ankle were treated with Ilizarov technique and steel needle internal fixation. There were 9 males and 3 females with an average age of 48.6 years (range, 19-66 years). The disease duration ranged from 1 to 16 months (mean, 6.8 months). Ankle joint involvement predominated in 7 cases, while midfoot involvement occurred in 5 cases; 3 cases presented with skin ulceration and soft tissue infection. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 31.2±9.0, 36-Item Short-Form Health Survey (SF-36)-Physical Component Summary (PCS) score was 32.6±6.8, and Mental Component Summary (MCS) score was 47.8±8.4. Postoperative assessments included wound healing, regular X-ray film/CT evaluations of fusion status, and effectiveness via AOFAS and SF-36-PCS, MCS scores.
RESULTS:
All operations were successfully completed without neurovascular complication. Two patients experienced delayed wound healing requiring intervention, and the others achieved primary healing. All patients were followed up 15-43 months (mean, 23.3 months). Imaging confirmed successful joint fusion within 13-21 weeks (mean, 16.8 weeks). At last follow-up, the AOFAS score was 72.5±6.4, and the SF-36-PCS and MCS scores were 63.2±8.4 and 76.7±5.3, respectively, all of which improved compared to preoperative levels, with significant differences ( P<0.05).
CONCLUSION
Ilizarov technique combined with steel needle internal fixation effectively restores walking function and achieves satisfactory short-term effectiveness in CN of the foot and ankle.

Objective To investigate the value of depth of invasion (DOI) and pattern of invasion (POI) in predicting recurrence and evaluating prognosis of early oral squamous cell carcinoma (OSCC). Methods Data of 109 patients with primary OSCC were retrospectively collected. The chi-square test was used to compare categorical variables of clinical data. Univariate and multivariate Logistic regression analyses were used to analyze the correlation between clinical data and tumor recurrence. Cox regression analysis was used to analyze the correlation between clinical data and overall survival of patients. Results Univariate analysis showed that POI, DOI and pathological grade were correlated with recurrence and poor prognosis of early OSCC. Multivariate Logistic regression analysis indicated that DOI was an influencing factor for OSCC recurrence (OR=4.515, 95%CI, 1.283 to 15.894,

Diabetic foot ulcer (DFU) is a serious complication of diabetes mellitus. 4%~10% of DM patients have DFU,of which 10%~20% of ulcers fail to heal. Traditional treatment or surgical treatment is difficult to cure DFU fundamentally. The amputation rate of DFU patients is as high as 25%,and the 5-year mortality rate after surgery is as high as 39%~68%. Mesenchymal stem cells (MSCs) have high self-renewal ability and multi-directional differentiation potential,which can promote vascular regeneration,wound healing,and improve blood supply. This article reviews the research progress of MSCs in the treatment of DFU.

Objective To explore the mediating role of cognitive function in the association between literacy level and depressive symptoms in middle-aged and elderly people in China. Methods Using the fourth national follow-up data of the China Health and Elderly Care Tracking Survey 2018, 8 124 middle-aged and elderly people aged 45 years and above were included as the study subjects. The PROCESS 4.0 program was used to test the mediating effect of cognitive function between literacy level and depressive symptoms, and the Bootstrap method was used for the mediator variable validation. Results The detection rate of depressive symptoms among middle-aged and elderly people in China was 38.10%. After controlling for gender, place of residence, marital status, smoking, alcohol consumption, and exercise, literacy level was a negative predictor of depressive symptoms in middle-aged and elderly people (β =-0.480, t =-11.248, P<0.001). Cognitive function accounted for 58.75% of the amount of mediating effect between literacy level and depressive symptoms. Conclusion Literacy level and cognitive function are associated with depressive symptoms in middle-aged and elderly people. Literacy level can influence depressive symptoms directly or indirectly through the mediation of cognitive dysfunction.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
