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 investigate the training effect of order-oriented medical students in Yunnan Province of China and related influencing factors and targeted suggestions, and to improve the training effect of order-oriented medical students in residency training bases in Yunnan Province.Methods:The stratified cluster sampling method was used to select 8 general residency training bases, and a questionnaire survey was performed among the 621 order-oriented students in these training bases. Finally, 616 valid questionnaires were collected. SPSS 26.0 was used to perform the two-sample rank sum test, the K-W test, and the ordered multinomial logistic regression analysis.Results:The training effect of the "5+3" order-oriented medical students in Yunnan Province was between generally good (48.29%) and good (45.37%). The effect of the provincial general training base is better than that of the municipal general training base, and most training students at the province level (167, 59.64%) thought that the training effect was good, while most of the training students at the prefecture or municipal level (194, 57.91%) thought that the training effect was generally good. When the teaching level of the teachers can meet the teaching work, the residential training effect of the order-oriented residential training students is well evaluated (197,68.17%). When skill training was carried out by the base at least once a month, most of the order-oriented trainees (96, 48.73%) thought that the training effect was good. The ordered multinomial logistic regression analysis showed that the nature of the base, sex, attitude towards policy, psychological state, teaching competency of teachers, perfection of the fund guarantee system, consistency of training plan with requirements, consistency of training process with requirements, and consistency of teaching activities with requirements were influencing factors for the training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province ( P<0.05). Conclusions:The training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province was between generally good and good. The training effect of bases can be improved by strengthening the construction of infrastructure, giving full play to the role of base linkage, perfecting the training plan, improving implementation and execution, building up a perfect fund guarantee system, enhancing the construction of general teaching team, emphasizing skill practice training, and implementing diversified training activities.

Background and purpose:Rectal cancer is one of the malignant tumors that seriously harm human health in the world,ranking third in incidence and second in mortality.With the development of social and economic level,the incidence and mortality of colorectal cancer in China are increasing,and China becomes one of the countries with high incidence of colorectal cancer disease in the world.The recommended treatment for locally advanced rectal cancer is neoadjuvant chemoradiotherapy combined with surgery,which greatly improves the prognosis of patients.However,intestinal adverse reactions such as diarrhea caused by neoadjuvant chemoradiotherapy are increased,and some patients are forced to delay or interrupt treatment due to serious side effects.Amifostine is a broad-spectrum normal cell protective agent,which has good protective effect against various radiochemotherapy toxicity.We conducted a retrospective analysis of patients with locally advanced rectal cancer who received neoadjuvant radiotherapy combined with irinotecan concurrent chemotherapy to investigate whether concurrent use of amifostine alleviated gastrointestinal and hematological toxicities.Methods:A retrospective cohort analysis was used in this study.Clinical data of patients with locally advanced rectal cancer who received neoadjuvant chemoradiotherapy at the Affiliated Cancer Hospital of Fudan University during the period of discharge from January 1,2018 to December 31,2019 were retrospectively collected.The patients were divided into 2 groups by whether amifostine was used during the same period.The main purpose of the study was to analyze whether amifostine can reduce gastrointestinal and hematological toxicities,and secondary objectives included whether amifostine could alter tumor marker levels,mesorectal fascia invasion(MRF)positive rate,extramural vascular invasion,positive rate of EMVI and pathological complete response(pCR).Using SAS9.4 statistical software,the normality test was carried out for continuous variables.The rank sum test of Wilcoxon was performed when the diarrhea grade did not conform to normal distribution.Analysis of variance was performed for intra-group comparison,and Wilcoxon rank sum test was performed for inter-group comparison.Because of the imbalance between groups,the difference between the two groups was compared using a generalized linear model.This study strictly followed the STrengthening the Reporting of OBservational studies in Epidemiology(STROBE)guidelines to ensure the transparency of the research methodology and the reliability of the results.Results:Finally,154 eligible patients were included,of whom 78 were in the amifostine group and 76 were in the control group.The highest grade of diarrhea in amifostine group was 1.00(1.00,1.00),lower than that in control group(2.00,3.00),and the difference between groups was statistically significant(P<0.01).After radiotherapy,white blood cell count(WBC),hemoglobin(HB)and absolute neutrophil count(ANC)from the two groups were obtained.ANC and platelet count(PLT)showed no statistically significant difference(P>0.05),and the lowest values of WBC,RBC and PLT did not have statistically significant difference between the two groups during neoadjuvant period(P>0.05).Amifostine may not alleviate hematological toxicity.Carbohydrate antigen 72-4(CA72-4)(Z=2.22,P=0.03),carbohydrate antigen 50(CA50)(Z=-2.49,P=0.01)and carbohydrate antigen 24-2(CA24-2)had statistically significant difference(Z=-2.29,P=0.02).There were no significant differences in MRF positive rate(P=0.11),EMVI positive rate(P=0.61)and pCR rate(P=0.94)between the two groups.Conclusion:Concurrent administration of amifostine in patients with locally advanced rectal cancer receiving neoadjuvant chemoradiotherapy can reduce gastrointestinal toxicity and reduce the levels of tumor markers CA72-4,CA50 and CA24-2.However,it may have no significant effect on improving hematological toxicity,MRF and EMVI positive rate and pCR rate.

Objective:To evaluate the safety and effectiveness of rubber band-assisted endoscopic submucosal excavation (RB-ESE) for gastric submucosal tumors (SMT).Methods:A retrospective study was conducted on data of gastric SMT patients who underwent ESE in Affiliated Hospital of Yangzhou University from January 2017 to August 2022. A total of 48 patients were selected and divided into two groups: RB-ESE group ( n=20) and the conventional ESE (C-ESE) group ( n=28). The operation time, bleeding rate and perforation rate during operation, the retention rate of the mucosal cap, the number of clips, postoperative complications, and the hospitalization time were analyzed. Additionally, correlations between complications and tumor size/location and between bleeding and perforation were evaluated. Results:No significant difference was found in the general conditions between the two groups ( P>0.05). The operation time of RB-ESE group (14.82±2.31 min) was significantly shorter than that of C-ESE group (23.70±3.67 min) ( t=-9.539, P<0.001). The intraoperative bleeding rates were 20.0% (4/20) and 42.9% (12/28) in the RB-ESE group and C-ESE group respectively ( χ2=2.743, P=0.098), while the intraoperative perforation rates were 25.0% (5/20) and 46.4% (13/28) respectively ( χ2=2.286, P=0.131). Furthermore, the mucosal cap preservation rate was notably higher in the RB-ESE group at 60.0% (12/20) compared with 7.1% (2/28) in the C-ESE group ( χ2=15.777, P<0.001). The number of clips applied to close the wound was 8.05±1.40 and 10.43±1.96 in the RB-ESE group and C-ESE group respectively ( t=4.925, P<0.001). The postoperative hospital stays were 4.35±0.75 days and 5.00±0.86 days respectively in two groups ( t=2.724, P=0.009). No postoperative bleeding or perforation occurred in either group. The results showed that the occurrence of perforation and bleeding were associated with tumor diameter. Patients with tumor size ≥2 cm showed increased proportions of intraoperative bleeding [68.4% (13/19), P<0.001] and perforation [78.9% (15/19), P<0.001]. There was a correlation between intraoperative bleeding and perforation ( P<0.001). Conclusion:RB-ESE proves to be an effective and safe approach for managing gastric SMT, offering advantages such as reduced operation time and hospital stays, improved retention of the mucosal cap post-operation, and less clips use. The results suggest that RB-ESE could be widely adopted for treating SMT.

Objective:To evaluate and compare efficacy of intravenous immunoglobulin (IVIG) versus recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) in the treatment of toxic epidermal necrolysis (TEN) .Methods:Clinical data were collected from patients with TEN treated with IVIG or rhTNFR:Fc in Wuhan No.1 Hospital from 2013 to 2019. There were 11 patients in the IVIG group, including 3 males and 8 females, aged 25-72 years, and the median TEN-specific severity-of-illness score (SCORTEN) was 3 points; there were 10 patients in the rhTNFR:Fc group, including 5 males and 5 females, aged 32-84 years, and the median SCORTEN was 2 points. These patients all showed no response to the 5-day treatment with prednisolone acetate at a dose of 0.6-1.0 mg·kg -1·d -1, and then received IVIG at a dose of 400 mg·kg -1·d -1 for 5 consecutive days, or subcutaneous injection of rhTNFR:Fc at a dose of 25 mg every other day for 4-6 sessions. Changes in skin lesions and adverse events were recorded in the 2 groups. Statistical analysis was carried out by using Mann-Whitney U test. Results:Compared with the rhTNFR:Fc group, the IVIG group showed a significant decrease in the time to onset of reduction of skin lesion exudate (1.73 ± 1.19 days vs. 3.00 ± 1.56 days, P < 0.05) , time to onset of pain relief in the lesion area (1.64 ± 1.28 days vs. 3.70 ± 1.63 days, P < 0.05) , time to lightening of color of the lesion base (2.45 ± 1.12 days vs. 3.90 ± 1.59 days, P < 0.05) , time to onset of new epidermis growth (3.09 ± 1.13 days vs. 5.20 ± 1.22 days, P < 0.05) , and in the time to onset of lesion drying at the intertriginous sites (4.82 ± 2.22 days vs. 7.90 ± 3.14 days, P < 0.05) . However, there was no significant difference in the length of hospital stay between the IVIG group (17.70 ± 8.33 days) and rhTNFR:Fc group (16.70 ± 4.71 days, P > 0.05) . No adverse reactions were observed during the treatment, and no recurrence or complications were found in the 21 patients during the follow-up of 6 months. Conclusion:IVIG and rhTNFR:Fc are both effective in the treatment of TEN, but IVIG is superior to rhTNFR:Fc in terms of the time to onset of pain relief, skin lesion exudate reduction and epidermal growth.

Objective:To evaluate role of Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil protein kinase 2 (ROCK2) signaling pathway in trilobatin-induced reduction of cerebral ischemia-reperfusion (I/R) injury in rats.Methods:Eighty clean-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 230-280 g, were divided into 4 groups ( n=20 each) using a random number table method: sham operation group (group S), cerebral I/R group (group IR), cerebral I/R plus trilobatin group (group T) and cerebral I/R plus trilobatin plus RhoA/ROCK2 signaling pathway agonist AA group (group A). The model of focal cerebral I/R injury was developed by middle cerebral artery occlusion in anesthetized animals.Trilobatin 15 mg/kg was given by gavage twice a day for 3 consecutive days in T and A groups.RhoA/ROCK2 signaling pathway agonist AA 10 mg/kg was intraperitoneally injected before each administration by gavage in group A. Neurobehavioral score was assessed at 24 h of reperfusion, then the rats were sacrificed, and the hippocampal tissues were isolated for determination of the apoptosis rate of hippocampal neurons (by flow cytometry), cerebral infarction volume (by TTC staining), and expression of phosphorylated RhoA (p-RhoA), ROCK2 and cleaved caspase-3 (by Western blot) and for microscopic examination of ultrastructure of hippocampal neurons (with a transmission electron microscope). Results:Compared with group S, the neurobehavioral score, apoptosis rate of hippocampal neurons, and cerebral infarction volume were significantly increased, the expression of p-RhoA, ROCK2 and cleaved caspase-3 was up-regulated ( P<0.05), and the pathological damage to hippocampal neurons was aggravated in group IR.Compared with group IR, the neurobehavioral score, apoptosis rate of hippocampal neurons and cerebral infarction volume were significantly decreased, the expression of p-RhoA, ROCK2 and cleaved caspase-3 was down-regulated ( P<0.05), and the pathological damage to hippocampal neurons was alleviated in group T. Compared with group T, the neurobehavioral score, apoptosis rate of hippocampal neurons, and cerebral infarction volume were significantly increased, the expression of p-RhoA, ROCK2 and cleaved caspase-3 was up-regulated ( P<0.05), and the pathological damage to hippocampal neurons was aggravated in group A. Conclusions:RhoA/ROCK2 signaling pathway is involved in trilobatin-induced reduction of cerebral I/R injury, which may be related to inhibition of apoptosis in hippocampal neurons of rats.

Objective:To summarize survival outcomes and prognostic factors in esophageal cancer (EC) patients treated with intensity-modulated radiotherapy (IMRT).Methods:A retrospective analysis was performed on the clinical and follow-up data of 1 637 patients with EC who were admitted to our hospital from January 2005 to December 2017 and met the inclusion criteria.The 5-year overall survival (OS), progression-free survival (PFS) and pattern of recurrence were analyzed. The Kaplan-Meier method was used to calculate survival rates, Log-rank test for univariate analysis and Cox method for multivariate analysis were used to detect survival difference.Results:1-year, 3-year and 5-year OS and PFS of the entire group were 65.9% and 45.8%, 34.2% and 25.0%, 27.0% and 18.5%, respectively. Median OS and PFS were 19.4 months (95% CI=18.0-20.7 months) and 10.4 months (95% CI=9.3-11.3 months), respectively. Univariate analysis showed that the sex, KPS, tumor location, T stage, N stage, M stage, TNM stage, radiation dose and treatment modality were prognostic factors for 5-year OS and PFS of EC patients ( P<0.05). Multivariate analysis indicated that the sex, KPS, TNM stage, radiation dose and treatment modality were independent prognostic factors for 5-year OS and PFS ( P<0.05). Conclusions:EC patients treated with IMRT can obtain a promising survival. The sex, KPS, TNM stage, radiation dose and treatment modality are independent prognostic factors for prognosis.

Objective:To examine the clinical characteristics, the potential relative factors for postoperative abdominal septic complications, and prognosis factors of surgical recurrence of Crohn disease (CD) patients after the first surgery.Methods:All the CD patients from Department of General Surgery, Jinling Hospital, Medical School of Nanjing University who had undergone at least one abdominal surgery from January 2007 to December 2017 were included for retrospective analysis. Hospital records were reviewed for information on clinical characteristics. Relative factors of postoperative abdominal septic complications were accessed by Logistic regression models, and prognosis factors of surgical recurrence were accessed by Cox proportional hazards regression models.Results:There were 1 048 patients included (733 males and 315 females), accounting for 1 513 operations. The age was 31(17) years and the length of resected small bowel was 30.0(40.0) cm at the first resection, 20.0(35.0) cm at the second resection, and 20.0(23.5) cm at the third resection. The length of resected small bowel was 25.0(40.0) cm at any resection. At the first abdominal surgery, 70.99%(744/1 048) patients were aged between 17 and 40 years, 66.98%(702/1 048) patients had ileocolonic disease, and 60.40%(633/1 048) patients had penetrating behavior. Penetrating behavior ( OR=8.594, 95% CI: 3.397 to 21.740, P<0.01) and current smoking status ( OR=2.671, 95% CI: 1.044 to 6.832, P=0.040) were significantly associated with an increased risk of postoperative septic complications, whereas staged operation ( OR=0.360, 95% CI: 0.184 to 0.707, P=0.003) was associated with a decreased risk. Male gender ( HR=1.500, 95% CI: 1.128 to 1.995, P=0.005), upper gastrointestinal disease ( HR=1.526, 95% CI: 1.033 to 2.255, P=0.034), penetrating behavior ( HR=1.506, 95% CI: 1.132 to 2.003, P=0.005) and emergency surgery ( HR=1.812, 95% CI: 1.375 to 2.387, P<0.01) were significantly associated with an increased risk of postoperative surgical recurrence, whereas staged operation ( HR=0.361, 95% CI: 0.227 to 0.574, P<0.01) was significantly associated with a decreased risk. Conclusions:In this cohort of CD patients receiving abdominal surgery from an inflammatory bowel disease center, the median age was 31 years and the median length of resected small bowel was 30 cm, at first resection. Patients who have risk factors of adverse postoperative outcome may be benefited from staged surgical approach.
