ObjectiveTo explore the relationship between negative life events and depression severity in adolescent patients with depressive disorder， as well as the chain mediating role of insomnia symptoms and quality of life. Methods374 outpatient patients and hospitalized patients with adolescent depressive disorders were enrolled. The Adolescent Life Event Scale （ASLEC）， the Insomnia Severity Index （ISI）， the World Health Organization Quality of Life Questionnaire Short Form （WHOQOL-BREF）， and the Center for Epidemiology Depression Scale （CES-D） were used to evaluate the negative life event situation， insomnia symptoms， quality of life level and depression severity of the subjects， respectively. In addition， the PROCESS 4.0 macroprogram was used to analyze the chain mediating effect of insomnia symptoms and quality of life between negative life events and depression severity in patients with adolescent depressive disorder. ResultsThe results of correlation analysis showed that there was a significant correlation between negative life events and insomnia symptoms， quality of life， and depression severity （all P<0.05）. In addition， the results of chain mediation showed that negative life events had a significant direct effect on depression severity， with an effect size of 0.12 （P<0.001）. Insomnia symptoms and quality of life played a mediating role in the relationship between negative life events and depression severity in patients with adolescent depressive disorders， with indirect effect sizes of 0.062 （95%CI： 0.040-0.087） and 0.091 （95%CI： 0.059-0.123）， respectively. It could also play a chain mediation role， and the effect size was 0.039 （95%CI： 0.024-0.057）. ConclusionNegative life events experienced by patients with adolescent depressive disorder not only directly affect the severity of depressive symptoms， but may also indirectly exacerbate depression through insomnia symptoms and quality of life.

Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective: To explore the characteristic of obesity in adolescents with major depressive disorder and its relationship with inflammatory cytokines. Methods : One hundred and forty adolescents with major depressive disorder were enrolled. According to the classification standard of body mass index(BMI) for adolescents in China, the patients were classified into underweight group, normal group, overweight group and obese group. The center for epidemiologic studies depression scale(CES-D) was used to evaluate symptoms of depression in patients, and ultrasensitive multiplex electrochemiluminescence detection technology was used to measure the levels of plasma inflammatory cytokines including interleukin(IL)-6,IL-17A,IL-1β,IL-6,IL-8 and tumour necrosis factor(TNF)-α. One-way ANOVA or Kruskal-WallisHtest and chi-square test were used for comparison between groups. Binary Logistic regression was used to analyze the influencing factors of obesity in adolescent patients with major depressive disorder. Results : Among the 140 adolescent patients with major depressive disorder, wasting were 9.3%(13/140), overweight were 17.9%(25/140) and obesity were 6.4%(9/140) respectively. There were statistically significant differences in gender(χ2=8.301,P<0.05) and inflammatory cytokines IL-6(H=16.217,P<0.01), IL-8(H=10.926,P<0.05) and TNF-α(H=7.879,P<0.05) among the four groups. Analysis of covariance showed that the difference in levels of the inflammatory cytokine IL-6(F=4.486,P<0.01) remained statistically significant after controlling for age, gender and antidepressant use. The results of multiple comparisons showed that compared with the wasting group, the plasma IL-6(Z=-3.843,PBonferroni calibrate<0.01) were higher in the obese group; compared with the normal group, the obesity rate of males was higher than that of females(χ2=8.812,PBonferroni calibrate<0.01), and the level of IL-6 in the obese group(Z=-3.023,PBonferroni calibrate<0.05) was higher. Binary Logistic regression analysis showed that plasma IL-6(OR=2.500,P<0.01) and gender(OR=11.292,P<0.01) were independent influencing factors for obesity in patients with adolescent depressive disorders. Conclusion There are gender differences in obesity rates in adolescents with depressive disorders, and obesity is associated with elevated levels of inflammatory cytokines.

Objective : To explore the predictive value of depression severity plasma thyroid-stimulating hormone(TSH) and brain-derived neurotrophic factor(BDNF) levels for agitated symptoms in patients with adolescent depressive disorder(MDD). Methods : Ninety-one patients with adolescent depressive disorder were enrolled, and the degree of agitation was assessed according to the modified outward aggressive behavior scale(MOAS); 24-item hamilton depression scale(HAMD24) was used to determine the severity of depression; chemiluminescence immunoassay(CLIA) was used to determine the plasma thyroid-stimulating hormone(TSH) level; and electrochemiluminescence immunoassay(ECL) was used to determine the plasma BDNF. SPSS 26.0 was used for statistical analysis of the data, Spearman correlation analysis was used to analyze the relationship between HAMD24and plasma TSH and BDNF levels and the degree of agitation, multiple linear regression analysis was used to analyze the factors influencing the degree of agitation in adolescents with MDD, and binary Logistic regression analysis and subjects′ work characteristic curves(ROC) were used to establish predictive models. Results: The degree of agitation in adolescent MDD patients was positively correlated with HAMD24total score(P<0.001); both HAMD24total score and plasma BDNF level were identified as risk factors for agitation severity(bothP<0.05); both HAMD24total score and plasma BDNF levels were risk factors for the degree of agitation(allP<0.05); HAMD24total score, plasma TSH, BDNF levels were all risk factors for concomitant agitation symptoms in adolescent MDD patients; ROC curve analysis showed that the three combined prediction models(AUC=0.889,P<0.001) had a higher predictive value than the single prediction model(P<0.01). Conclusion Concomitant agitation symptoms in adolescents with MDD are strongly associated with HAMD24total score and plasma TSH and BDNF levels, and the three combined models have good predictive power.

Due to the immaturity of visualization and quantitative analysis methods,the utilization rate of level 3 characteristics is seriously insufficient.In this work,based on the wet-membrane method and scanning electrochemical microscopy(SECM),and the introduction of conductive black ink to enhance the visualization effect,a systematic level 3 feature quantitative method was developed.Firstly,the feasibility and effect of the multi-level characteristics extraction strategy of latent fingerprints was investigated.Then,the influences of various deposition conditions on the level 3 features were explored.The results showed that the higher the deposition pressure,the wider the ridges,and the smaller the pore size.Moreover,excessive oil content could cause the pore size to be smaller and even been covered.Subsequently,the quantitative method was established from various pore characteristics such as pore number,pore activity,pore size,pore-to-pore distance and pore-to-pore angle.The stability of the level 3 features(pore number,pore-to-pore distance and pore-to-pore angle)was confirmed via repeated experiments on the same fingerprint region.After stability test,the recognition ability of three indicators was investigated for different fingerprints,verifying the uniqueness of pore-to-pore distance and pore-to-pore angle.Finally,a multiple recognition strategy was proposed that combined frequency distribution fitting curves for pore-to-pore distance and angle with other level 3 details,and was successfully applied to incomplete fingerprint recognition.This ink-enhanced optical and electrochemical extraction method and quantitative analysis provided a new path for fingerprint recognition.

Objective:To compare the efficacy of neuroendoscopy-assisted small bone window craniotomy and large bone flap craniotomy for acute subdural hematoma (ASDH) evacuation in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 57 elderly patients with ASDH admitted to Chongqing University Fuling Hospital from November 2020 to November 2023, including 27 males and 30 females, aged 65-89 years [(75.0±7.0)years]. The preoperative Glasgow coma scale (GCS) ranged 8-15 points [11.0(11.0, 12.0)points]. Among them, 27 patients were treated with neuroendoscopy-assisted small bone window craniotomy to evacuate ASDH (small bone window group) and 30 received large bone flap craniotomy to evacuate ASDH (large bone flap group). The following parameters were compared between the two groups: surgical duration, intraoperative blood loss, and length of hospital stay; residual subdural hematoma volume before surgery and at 1 day after surgery; GCS before surgery, at 1 and 3 days after surgery; good rate of Glasgow outcome scale (GOS) at 7 days and 6 months after surgery; and postoperative complication rate.Results:All the patients were followed up for 6 months. The surgical duration, intraoperative blood loss, and length of hospital stay were 89.0(85.0, 96.0)minutes, 65.0(55.0, 85.0)ml, and 15.0(14.0, 16.0)days, respectively in the small bone window group, which were shorter or less than 135.0(127.5, 150.0)minutes, 332.0(308.0, 367.5)ml, and 18.5(16.0, 20.0)days in the large bone flap group ( P<0.01). There was no statistically significant difference in the residual subdural hematoma volume between the two groups before surgery and at 1 day after surgery ( P>0.05). No statistically significant difference was found in GCS scores between the two groups before surgery ( P>0.05), while the GCS scores in the small bone window group at 1 and 3 days after surgery [12.0(12.0, 13.0)points and 15.0(14.0, 15.0)points] were higher than 11.5(11.0, 12.0)points and 13.0(12.8, 14.0)points in the large bone flap group ( P<0.01). The good rate of GOS in the small bone window group at 7 days after surgery was 100% (27/27), higher than 77% (23/30) in the large bone flap group ( P<0.05), but no statistically significant difference was found in the good rate of GOS between the two groups at 6 months after surgery ( P>0.05). Two patients in the small bone window group had pulmonary infection after surgery, with a complication rate of 7% (2/27), while in the large bone flap group, four patients had pulmonary infection, two epidural hematoma, one intracranial infection, one delayed wound healing, one subcutaneous fluid accumulation, and one epilepsy after surgery, with a complication rate of 33% (10/30) ( P<0.05). Conclusion:Compared with the conventional large bone flap craniotomy, neuroendoscopy-assisted small bone window craniotomy can shorten the surgical duration and length of hospital stay, reduce the intraoperative bleeding volume, promote early functional recovery, improve prognosis, and reduce the complication rate in elderly patients with ASDH.

Background and purpose:Accurately locating pulmonary nodules is the key to the success of thoracoscopic surgery.This study aimed to investigate the strategy and evaluate the feasibility,safety,and clinical value of thoracoscopic surgical treatment for pulmonary nodules located beneath the interlobar pleura and close to the pulmonary hilum.Methods:The patients who underwent pulmonary nodule surgery at Liaocheng Tumor Hospital from May 2023 to November 2024 were enrolled,and the patients who did not meet the inclusion criteria were excluded.This study was approved by the Ethics Committee of Liaocheng Tumor Hospital(EC-20240112-1020)and informed consent was obtained from the patients.The research was designed as a prospective single-arm study.The patients were treated with wedge resection,which was performed following CT-guided localization,where the location needle was inserted through the interlobar pleura.The feasibility of the procedure was evaluated by analyzing the success rate of preoperative localization and perioperative complications.Results:A total of 28 patients who met the inclusion criteria were included in this study.There were 5 male and 23 female patients with an average age of(56.0±8.5)years(range 38-69 years).In all,28 patients with 28 nodules underwent thoracoscopic wedge resection,and the preoperative CT-guided localization was successfully performed in all patients,without urgent complications.The mean operation time of thoracoscopic surgery was(15.6±4.0)min,intraoperative bleeding was(20.9±14.3)mL,and postoperative drainage was(214.3±62.2)mL.No cases of postoperative air leaks or conversion to thoracotomy were observed.The average length of hospital stay was(5.4±0.9)days.The postoperative histological diagnosis revealed 3 benign lesions(pulmonary fibrosis in 2 cases,atypical adenomatous hyperplasia in 1 case)and 25 malignant lesions(adenocarcinoma in situ in 5 cases,minimally invasive adenocarcinoma in 16 cases,and invasive adenocarcinoma in 4 cases).Conclusion:Thoracoscopic wedge resection following CT-guided nodule localization through the interlobar pleura is a feasible approach for nodules located beneath the interlobar pleura and close to the pulmonary hilum.The method ensures precise tumor localization,adequate margin,and minimal loss of normal lung tissue,with a low incidence of postoperative complication,which has important guiding significance for the surgical treatment of pulmonary nodules in such special locations.
