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］

OBJECTIVES: To compare the efficacy of toric implantable collamer lens (Toric-ICL) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction in patients with moderate to high myopia complicated with astigmatism. METHODS: We retrospectively collected data from 64 patients (aged 18-42 years) with moderate to high myopia complicated with astigmatism (128 eyes) undergoing either Toric-ICL (28 patients/56 eyes) or FS-LASIK (36 patients/72 eyes) at our department between January, 2019 and December, 2020. The changes of uncorrected distance visual acuity (UCVA), spherical equivalent (SE), mean astigmatism correction index (CI), corneal endothelial cell density (ECD) and intraocular pressure (IOP) following the procedures were compared between the two groups. RESULTS: In FS-LASIK group, all the eyes (72/72) achieved an UCVA≥1.0, similar to the rate in Toric-ICL group (55/56 eyes; P=0.2374). The postoperative SE was also comparable between FS-LASIK and Toric-ICL groups [0.43±0.06 D (range: -1.0 to 1.50 D) vs 0.38±0.05 D (range: -0.75 to 1.00 D); P=0.56]. The mean astigmatism CI was significantly higher in FS-LASIK group than in Toric-ICL group (0.8561 vs 0.7176; P<0.0001), and 88.89% of the eyes in FS-LASIK group and 69.64% in Toric-ICL group had postoperative astigmatism ≤0.50 D. No significant changes were observed in postoperative corneal ECD in FS-LASIK group, whereas ECD decreased significantly after the procedure in Toric-ICL group (P=0.0057). The patients undergoing Toric-ICL exhibited no significant changes of postoperative IOP, but the patients receiving FS-LASIK had significantly reduced IOP after the procedure (P<0.001). CONCLUSIONS Although the patients included in Toric-ICL group had higher myopia and astigmatism, Toric-ICL still showed better predictability and efficacy for astigmatic correction in Toric-ICL group. Toric-ICL is an effective and safe equivalent of FS-LASIK for correcting moderate myopia but can be more advantageous for correcting high myopia with astigmatism.

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 predictive value of global longitudinal strain(GLS)measured by cardiac magnetic resonance(CMR)feature-tracking technique for left ventricular remodeling(LVR)after percutaneous coronary intervention(PCI)in patients with acute ST-segment elevation myocardial infarction(STEMI).Methods A total of 403 patients undergoing PCI for acute STEMI were prospectively recruited from multiple centers in China.CMR examinations were performed one week(7±2 days)and 6 months after myocardial infarction to obtain GLS,global radial strain(GRS),global circumferential strain(GCS),ejection fraction(LVEF)and infarct size(IS).The primary endpoint was LVR,defined as an increase of left ventricle end-diastolic volume by≥20%or an increase of left ventricle end-systolic volume by≥15%from the baseline determined by CMR at 6 months.Logistic regression analysis was performed to evaluate the predictive value of CMR parameters for LVR.Results LVR occurred in 101 of the patients at 6 months after myocardial infarction.Compared with those without LVR(n=302),the patients in LVR group exhibited significantly higher GLS and GCS(P<0.001)and lower GRS and LVEF(P<0.001).Logistic regression analysis indicated that both GLS(OR=1.387,95%CI:1.223-1.573;P<0.001)and LVEF(OR=0.951,95%CI:0.914-0.990;P=0.015)were independent predictors of LVR.ROC curve analysis showed that at the optimal cutoff value of-10.6%,GLS had a sensitivity of 74.3%and a specificity of 71.9%for predicting LVR.The AUC of GLS was similar to that of LVEF for predicting LVR(P=0.146),but was significantly greater than those of other parameters such as GCS,GRS and IS(P<0.05);the AUC of LVEF did not differ significantly from those of the other parameters(P>0.05).Conclusion In patients receiving PCI for STEMI,GLS measured by CMR is a significant predictor of LVR occurrence with better performance than GRS,GCS,IS and LVEF.

Objective To evaluate the diagnostic value of endoscopic ultrasonography(EUS)in the preoperative staging and ductal dilatation of duodenal papillary carcinoma and analyze the factors influencing its diagnostic accuracy.Methods A cross-sectional trial was conducted on the patients with pathologically-diagnosed duodenal papillary carcinoma and undergoing EUS in the First Affiliated Hospital of Army Medical University from January 2018 to August 2023.The diagnostic value of EUS for the preoperative staging of duodenal papillary carcinoma was evaluated using sensitivity,specificity,positive predictive value,negative predictive value,and accuracy.Univariate and multivariate analyses were performed to determine the factors affecting the diagnostic accuracy of EUS.Results A total of 102 patients with duodenal papillary carcinoma were included,including 59 males and 43 females,at a mean age of 62 years,and all of them underwent EUS before diagnosis.The accuracy of EUS for tumor T-staging was 86.27％,the sensitivity and specificity for T1,T2,T3,and T4 lesions were 84.21％,92.31％,85.00％,60.00％,and 95.31％,88.89％,96.34％,and 98.97％,respectively.The positive predictive value for T-staging of T1,T2,T3,and T4 lesions was 91.43％,83.72％,85.00％,and 75.00％,and the negative predictive values were 91.04％,94.92％,96.34％,and 97.96％,respectively.There were 14 patients whose T-staging was incorrectly staged by EUS.The accuracy of EUS in assessing intraductal dilatation was 75.49％,and the sensitivity,specificity,positive predictive value,and negative predictive value for ductal dilatation were 96.97％,66.67％,98.97％,and 40.00％,respectively.In addition,the independent predictors of diagnostic accuracy of EUS for pancreatic duct dilatation were nerve infiltration,tumor size,and T stage;whereas the independent risk factors for diagnostic accuracy of bile duct dilatation were nerve infiltration and alkaline phosphatase.Conclusion EUS has quite higher diagnostic value for preoperative staging of duodenal papillary carcinoma,and nerve infiltration,tumor size,T stage,T stage and alkaline phosphatase may be the influencing factors for its diagnostic accuracy.

Objective:To evaluate the efficacy of Yiqi Yangyin Jiedu Decoction in the treatment of patients with pulmonary nodules and qi-yin deficiency syndrome after early lung cancer surgery.Methods:Randomized controlled trial was conducted. A total of 76 patients with lung nodules and qi-yin deficiency syndrome after early lung cancer surgery at the Oncology Department of Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from March to September 2020 were selected and randomly divided into two groups using a random number table method, with 38 cases in each group. The control group received symptomatic treatment, while the treatment group took Yiqi Yangyin Jiedu Decoction from the first day after enrollment. Both groups were treated for 6 months and followed up for 2 years. TCM syndrome scores before and after treatment were evaluated; the patients' activity status was evaluated using the Eastern Oncology Collaborative Group Activity Status (ECOG PS) score in the United States, and electrochemiluminescence was used to detect carcinoembryonic antigen (CEA) and neuron specific enolase (NSE). Flow cytometry was used to detect the percentage of T lymphocyte subsets CD3 +and CD4 +, and ELISA was used to detect TGF-β Horizontal. The patients' weight was recorded and their weight changes after treatment were observed. Adverse reactions during treatment were observed and recorded, the efficacy of TCM syndromes and pulmonary nodules was evaluated. Results:During the observation period, one case was lost to follow-up in the treatment group and three cases were lost to follow-up in the control group. Finally, 37 cases in the treatment group and 35 cases in the control group completed the observation. After the treatment, the panting (0.27±0.07 vs. 0.68±0.12, t=17.66), spontaneous sweating and night sweating (0.16±0.16 vs. 0.79±0.16, t=16.55) score of the treatment group were lower than those in the control group ( P<0.01); insomnia (0.15±0.08 vs. 0.54±0.13, t=15.52) score of the control group was lower than that of the treatment group ( P<0.01). The effective rate of TCM syndrome in treatment group was 81.08% (30/37), higher than 54.29% (19/35) in control group ( Z=-2.00, P=0.040). After the treatment, the ECOG PS score stability rate in the treatment group was 89.19% (33/37), higher than 82.86% (29/35) in control group, without statistical significance ( χ2=0.19, P>0.05). The increase and stable rate of body weight was 88.10% (32/37) in treatment group and 62.86% (22/35) in control group ( χ2=5.36, P<0.05). After 2-year follow-up, the control rate of pulmonary nodules in the treatment group was 91.89% (34/37), while in the control group it was 65.71% (23/35). The difference between the two groups was statistically significant ( χ2=7.47, P<0.01). After the treatment, the level of NSE [(12.54±2.52)ng/L vs. (13.85±2.71)ng/L, t=-2.12], TGF-β [(218.38±102.63)ng/L vs. (301.24±193.69)ng/L, t=-2.29] in treatment group were lower than those in the control group ( P<0.05), and the level of CD3 +T cells [(70.60±7.90)% vs. (65.99±9.27)%, t=2.32] in treatment group was higher than that of the control group ( P<0.05). Conclusion:Yiqi Yangyin Jiedu Decoction can delay the development of pulmonary nodules in patients after early lung cancer surgery, increasing the body weight of patients, relieving the TCM syndromes and improve the immune function of patients, with the potential to prevent and treat the occurrence and development of early lung cancer.

The standardized workflow of computer-aided static guided implant surgery includes preoperative exami-nation,data acquisition,guide design,guide fabrication and surgery.Errors may occur at each step,leading to irrevers-ible cumulative effects and thus impacting the accuracy of implant placement.However,clinicians tend to focus on fac-tors causing errors in surgical operations,ignoring the possibility of irreversible errors in nonstandard guided surgery.Based on the clinical practice of domestic experts and research progress at home and abroad,this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection,data collection,guide de-signing and manufacturing and describes strategies to resolve errors so as to gain expert consensus.Consensus recom-mendation:1.Preoperative considerations:the appropriate implant guide type should be selected according to the pa-tient's oral condition before surgery,and a retaining screw-assisted support guide should be selected if necessary.2.Da-ta acquisition should be standardized as much as possible,including beam CT and extraoral scanning.CBCT performed with the patient's head fixed and with a small field of view is recommended.For patients with metal prostheses inside the mouth,a registration marker guide should be used,and the ambient temperature and light of the external oral scan-ner should be reasonably controlled.3.Optimization of computer-aided design:it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers.Properly designing the retaining screws,extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors.4.Improving computer-aided production:it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postpro-cessing procedures.
