Objective: To explore the core features of trait aggression in children and adolescents, so as to provide a theoretical basis for behavioral interventions targeting the central psychological characteristics of aggression in children and adolescents. Methods: From March to May 2020, a simple random convenience sampling method was employed to recruit 39 165 students from grades 4 to 12 in Sichuan, Chongqing, Guizhou, and Shandong. Data were collected via online questionnaires, with all participants completing the Chinese Version of the Aggression Questionnaire. Psychometric network analysis was utilized for data processing. Results: Trait aggression among Chinese children and adolescents was at a moderately low level. The core nodes of the network structure included physical aggression [if someone intentionally causes trouble for me, I will hit them severely (AGG6); if someone hits me, I will retaliate (AGG11)] and self aggression [When I am very irritable, I think of hurting myself (AGG5); when I am in a bad mood, I engage in behaviors that harm my health, such as overeating (AGG25)]. Across grade levels, core nodes primarily originated from the anger dimension [When I m angry, I feel like a powder magazine that could explode at any moment (AGG13); I can t control my temper (AGG18); I am prone to getting angry when I see things that are not pleasing to the eye (AGG23); I will get angry for no reason (AGG27)]. Except for grades 7 and 9, core nodes in other grades included the verbal aggression dimension [I am prone to arguments with people (AGG22)]. Before grade 8, core nodes incorporated the self aggression dimension (AGG 5, AGG 25); after grade 8, core nodes included the physical aggression dimension [AGG 6, AGG 11, I fight slightly more than others (AGG16), and if people around me make things difficult for me to a certain extent, I will fight with them (AGG26)]. No statistically significant differences were found in the trait aggression network structures across grades, genders, or within gender comparisons of different grades. Conclusion These findings broaden our understanding of aggression in children and adolescents, suggesting that behavioral interventions can effectively reduce aggressive behaviors in this population.

High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

Objective:To Explore the changes of annexin A2 and vascular endothelial cadherin (VE-Cad) in patients with cerebral infarction (CI) undergoing emergency thrombolysis, and analyze their relationship with progression within 10 d.Methods:Using a prospective research method, 78 patients with CI were selected from October 2019 to June 2022 in Xi'an International Medical Center Hospital, and all patients were treated with emergency thrombolysis. The serum levels of annexin A2 and VE-Cad before and after thrombolysis were measured by enzyme-linked immunosorbent assay, and the National Institute stroke scale (NIHSS) was used to assess patients' neurologic impairment. The baseline data, imaging findings at admission and routine laboratory examination indexes were recorded. The progression within 10 d after thrombolysis was recorded. Pearson correlation analysis was used to analyze the correlation between annexin A2, VE-Cad and NIHSS score. Multivariate Logistic regression was used to analyze the independent risk factors of progression within 10 d after thrombolysis in patients with CI. The value of annexin A2 and VE-Cad in predicting the progression within 10 d after thrombolysis in patients with CI was evaluated by the receiver operating characteristics (ROC) curve. A restricted cubic spline model was drawn to evaluate the dose-response relationship between annexin A2, VE-Cad and the progression within 10 d after thrombolysis in patients with CI.Results:Compared with before thrombolysis, the annexin A2 after thrombolysis was significantly higher: (24.50 ± 3.27) μg/L vs. (20.86 ± 3.84) μg/L, the VE-Cad and NIHSS score were significantly lower: (4.72 ± 1.05) mg/L vs. (6.81 ± 1.31) mg/L and (8.64 ± 2.35) scores vs. (13.01 ± 2.86) scores, and there were statistical differences ( P<0.01). Before and after thrombolysis, Pearson correlation analysis result showed there was a negative correlation between annexin A2 and NIHSS score ( r =-0.796 and - 0.568, P<0.01), and a positive correlation between VE-Cad and NIHSS score ( r = 0.820 and 0.502, P<0.01). Among 78 patients with CI treated with emergency thrombolysis, 7 cases (8.97%) experienced progression within 10 d. There were statistical differences in hypertension, diabetes, hyperlipidemia, onset to thrombolysis time, infarct site, systolic blood pressure, triacylglycerol, high-density lipoprotein cholesterol, and the NIHSS score, annexin A2, VE-Cad before and after thrombolysis between patients with progression within 10 d after thrombolysis and patients without progression within 10 d after thrombolysis ( P<0.05 or <0.01); there were no statistical differences in gender composition, age, body mass index, coronary heart disease, atrial fibrillation, smoking, alcohol consumption, family history of stroke, carotid plaques, blood glucose, diastolic blood pressure, white blood cell count, platelet count, total cholesterol low-density lipoprotein cholesterol between the two groups ( P>0.05). After adjusting for hypertension, diabetes and hyperlipidemia, multivariate Logistic regression analysis result showed that the infarction site, onset to thrombolysis time, VE-Cad after thrombolysis and annexin A2 after thrombolysis were still independent factors of progression within 10 d after thrombolysis in patients with CI ( OR = 2.570, 2.496, 3.147 and 0.352; 95% CI 1.285 to 5.139, 1.303 to 4.781, 1.629 to 6.080 and 0.158 to 0.782; P<0.05 or <0.01). ROC curve analysis results showed that the area under the curve of annexin A2 combined with VE-Cad after thrombolysis to predict the progression within 10 d after thrombolysis in patients with CI was significantly larger than that of annexin A2 and VE-Cad after thrombolysis alone (0.898 vs. 0.822 and 0.799, χ2 = 2.17 and 1.98, P = 0.039 and 0.048). The optimal cutoff values of annexin A2 and VE-Cad after thrombolysis were <23.27 μg/L and >4.92 mg/L, with a sensitivity of 88.24%, and a specificity of 77.05%. The restricted cubic spline analysis result showed that the continuous changes in annexin A2 after thrombolysis were roughly negatively correlated with the progression within 10 d after thrombolysis in patients with CI ( OR = 0.720, 95% CI 0.561 to 0.930, P = 0.010), the continuous changes in VE-Cad after thrombolysis were roughly positively correlated with the progression within 10 d after thrombolysis in patients with CI ( OR = 1.450, 95% CI 1.126 to 1.188, P = 0.004). When annexin A2<23.80 ng/L and VE-Cad>5.25 mg/L after thrombolysis, the risk of progression within 10 d after thrombolysis in patients with CI significantly increased. Conclusions:The expression of annexin A2 increases and VE-Cad decreases after emergency thrombolysis in patients with CI, and the expression levels of both are closely related to the degree of neurologic impairment, and the risk of progression within 10 d after thrombolysis could be determined clinically by detecting their changes.

Objective:To evaluate the long-term clinical efficacy and the influence on anal function of surgery combined with ustekinumab (UST) in active Crohn's disease (CD) patients with perianal fistula.Methods:A retrospective cohort study was conducted. Clinical data of active CD patients with perianal fistula undergoing surgery combined with UST at Longhua Hospital of Shanghai University of Traditional Chinese Medicine from August 2020 to December 2022 were collected. The primary endpoints were clinical healing rate, Wexner score, and anorectal manometry values at week 52 of treatment. Secondary endpoints included the Crohn's disease activity index (CDAI), perianal Crohn's disease activity index (PDAI), laboratory indicators [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), fecal calprotectin (FC) ], endoscopic remission rate, Van Assche score, and radiographic healing rate at week 52 of treatment.Results:A total of 28 patients were included, with 22 males (78.6%) and 6 females (21.4%) ; age (25.2 ± 7.7) (16.0-52.0) years. There was 1 patient (3.6%) of simple anal fistula. There were 27 patients (96.4%) of complex anal fistulas, including 12 of high intersphincteric type, 15 of high transsphincteric type, in which 15 with branched tracts (or ≥2 fistula tracts). The pre-treatment CDAI was 187.0 (156.0, 245.0), and the PDAI was 10.0 (9.0, 12.0). Among the 28 patients, 23 (82.1%) underwent fistulotomy, 1 (3.6%) underwent transanal opening of intersphincteric space (TROPIS), and 4 (14.3%) underwent video-assisted anal fistula treatment (VAAFT) combined with fistula-tract laser closure (FiLaC). All the patients received UST treatment postoperatively, without concurrent use of immunosuppressants or corticosteroid therapy. At week 52 of treatment, 28 (100%) patients achieved clinical healing. Compared to pre-treatment, Wexner score of patients at week 52 of treatment was significantly lower [0 (0, 0) vs. 1.0 (0, 3.0), P < 0.001], maximum anal sphincter pressure increased [ (137.6±40.9) mmHg vs. (105.1±29.2) mmHg, P < 0.001], maximum anal sphincter contraction time extended [9.0 (5.0, 15.0) s vs. 4.0 (2.0, 6.0) s, P < 0.001], and there was no significant decrease in anal resting pressure ( P > 0.05). Compared to pre-treatment, CDAI, PDAI, Van Assche scores, and simple endoscopic score for Crohn's disease (SES-CD) of patients at week 52 of treatment all significantly decreased (all P < 0.001), and CRP, ESR, and FC all decreased (all P < 0.05), with statistically significant differences. The radiographic healing rate at week 52 of treatment was 75.0% (21/28), and the radiographic remission rate was 92.9% (26/28). The endoscopic remission rate was 57.1% (16/28), and the endoscopic response rate was 82.1% (23/28) . Conclusion:The long-term clinical healing rate of active CD patients with perianal fistula receiving surgery combined with UST is high, and the anal function can be improved significantly.

Objective:To evaluate the effects of different volumes of ropivacaine for iliopsoas muscle plane block on quadriceps strength in patients undergoing hip arthroplasty.Methods:In this prospective study, 75 patients of either sex, aged 40-80 yr, with a body mass index of 18.5-30.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, undergoing elective hip arthroplasty from June to December 2023 at Baoding First Central Hospital, were randomized into 3 groups ( n=25 each) by using a computer-generated randomization sequence: ropivacaine 5 ml group (group Ⅰ), ropivacaine 10 ml group (group Ⅱ), and ropivacaine 15 ml group (group Ⅲ). Before induction of anesthesia, iliopsoas muscle plane block was performed with 0.5% ropivacaine 5, 10 and 15 ml in Ⅰ, Ⅱ and Ⅲ groups, respectively. The lateral femoral cutaneous nerve block was carried out using 0.5% ropivacaine 5 ml in all the three groups. The quadriceps muscle strength and status of quadriceps motor block in the affected limb were assessed on admission to postanesthesia care unit (PACU) and at 2, 4, 6, 24 and 48 h after surgery. The consumption of dezocine, score for patient′s satisfaction with analgesia, and occurrence of complications were recorded. Results:Compared with group Ⅰ, the quadriceps muscle strength scores were significantly decreased on admission to PACU and at 2, 4 and 6 h postoperatively in group Ⅲ, the rate of quadriceps motor block was significantly increased on admission to PACU in group Ⅱ, and the rate of quadriceps motor block was significantly increased on admission to PACU and at 2 and 4 h postoperatively in group Ⅲ ( P<0.05), and the consumption of dezocine was significantly decreased in group Ⅱ and group Ⅲ ( P<0.05). Conclusions:The recommended volume of ropivacaine for iliopsoas plane block is 10 ml in patients undergoing hip arthroplasty.

Objective To investigate the mechanisms by which Porphyromonas gingivalis(P.gingivalis)promotes the malignant progression of oral squamous cell carcinoma(OSCC)through the recruitment of chemokine receptor 6-positive(CCR6+)regulatory T cells(Treg)in the tumor microenvironment(TME).Methods The Cancer Genome Atlas(TCGA)database was used to analyze the correlation between chemokine ligand 20(CCL20),CCR6,and Treg.The Treg enrichment index and the expression levels of interleukin(IL)-10 and tumor necrosis factor β1(TGF-β1)were assessed in the high CCR6 expression group of OSCC patients.C57BL/6 mice were randomly assigned to a control group and an experimental group(n=6 in each group).The control group received a single injection of 100 μL SCC7,a mice head and neck squamous carcinoma cell line,while the experimental group received a single injection of 100 μL mixture of SCC7 cells and P.gingivalis in the cheek.After two weeks,the mice were sacrificed,and immunohistochemistry was performed to assess the expression levels of CCR6 and forkhead box protein 3(FOXP3)in OSCC.Flow cytometry was performed to analyze the effects of P.gingivalis on OSCC malignant biological behavior,CCR6+Treg cells,and the immune microenvironment.Results Bioinformatics analysis revealed a correlation between CCL20,CCR6,and Treg(r=0.373,P＜0.0001).OSCC patients with high CCR6 expression showed higher Treg enrichment scores and increased IL-10 expression.Animal experiments showed that P.gingivalis promoted the increase in the tumor volume(mm3)(0.294±0.105 in the control group and 0.526±0.101 in the experimental group,P＜0.01)and mass(mg)(206.200±53.950 in the control group and 376.000±119.200 in the experimental group,P＜0.01)in mice with OSCC.Immunohistochemistry confirmed a correlation between CCR6 and FOXP3(r=0.659,P＜0.05),and P.gingivalis promoted the expression of CCR6 and FOXP3.Flow cytometry analysis showed that P.gingivalis increased the proportion of CCR6+Treg(％)(13.780±1.506 in the control group and 18.260±2.257 in the experimental group,P＜0.01)and decreased the proportion of CD8+T cells(％)(27.120±1.647 in the control group and 21.060±3.148 in the experimental group,P＜0.01)in OSCC,thereby promoting the formation of a immunosuppressive microenvironment.Conclusion P.gingivalis promotes the malignant progression of OSCC by recruiting CCR6+Treg cells to form an immunosuppressive TME.

Objective To evaluate the diagnostic value of prostate health index(PHI)and prostate health index density(PHID)in identifying intermediate-to high-risk prostate cancer(PCa).Methods Clinical data of 160 treatment-na?ve patients with highly suspected PCa,who underwent initial prostate biopsy in our hospital during Jul.2022 and Feb.2024,were retrospectively analyzed.Data included age,body mass index(BMI),prostate volume(PV),total prostate-specific antigen(tPSA),free PSA(fPSA),[-2]proPSA(p2PSA),PHI and PHID.Biopsy-positive results were stratified according to the EAU D'Amico risk criteria.Receiver operating characteristic(ROC)curve and multivariate logistic regression analysis were employed to assess the diagnostic performance of PHI and PHID in predicting PCa and identifying intermediate-to high-risk PCa.Results There were statistically significant differences in tPSA,p2PSA,PHI and PHID between the negative and positive groups,as well as among the low-,medium-and high-risk groups(P＜0.01).Both PHI and PHID demonstrated good diagnostic performance in predicting PCa(AUC=0.820 8 and 0.875 7,respectively;all P＜0.001),and in identifying intermediate-to high-risk PCa(AUC=0.838 0 and 0.878 3,respectively;all P＜0.001).Compared to the baseline model,the incorporation of PHI and PHID individually into the multivariate model significantly improved the screening performance for PCa(AUC=0.910 and 0.898,respectively;all P＜0.001).Conclusion PHI and PHID exhibit high diagnostic efficacy in screening PCa,particularly in identifying intermediate-to high-risk disease.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.

Objective:To analyze the neuropsychological characteristics of patients with chronic heart failure (CHF) complicated by mild cognitive impairment (MCI) and investigate the factors that influence the development of CHF complicated by MCI.Methods:A case-control study was conducted to retrospectively analyze the clinical data of 98 patients with CHF admitted to Baoji Hospital of Traditional Chinese Medicine from January 2019 to October 2020. Based on the Petersen MCI screening criteria, the patients were divided into the MCI group ( n = 48) and the normal cognitive group (NC group, n = 50). The neuropsychological characteristics were analyzed using the Mini-Mental State Examination and the Montreal Cognitive Assessment. The cognitive domain scores of the two groups were tested and compared. Logistic regression analysis was performed to identify the factors influencing the development of CHF complicated by MCI. Results:The total scores of the Mini-Mental State Examination and the Montreal Cognitive Assessment in the NC group were 28.45 ± 1.10 and 27.90 ± 1.35, respectively, which were significantly higher than those in the MCI group (23.50 ± 2.25, 22.95 ± 1.35, t = 13.92, 18.15, both P < 0.001). In addition, the NC group outperformed the MCI group in terms of the number of correct readings, time taken, attention, visuospatial function, memory, and language function ( t = 2.94, 7.29, 3.15, 9.90, 14.69, 4.87, all P < 0.01). The MCI group had a greater proportion of patients who were aged ≥ 65 years, had an education level of junior high school or below, experienced sleep disorders, and were classified as New York Heart Association (NYHA) functional class Ⅲ, compared with the NC group ( χ2 = 4.18, 4.08, 6.88, 4.70, all P < 0.05). Additionally, the cardiac output was lower in the MCI group than in the NC group ( t = 4.70, P < 0.05). Logistic regression analysis revealed that age ≥ 65 years ( OR = 3.904, 95% CI: 1.530-9.963), education level of junior high school or below ( OR = 2.565, 95% CI: 1.571-4.187), sleep disorders ( OR = 3.080, 95% CI: 1.445-6.564), and low cardiac output ( OR = 1.784, 95% CI: 1.168-2.725) were independent risk factors for CHF complicated by MCI ( P < 0.05). Conclusions:Patients with CHF complicated by MCI are more likely to experience impairments in visuospatial function, executive function, attention, language function, and memory. Independent risk factors for CHF complicated by MCI include age ≥ 65 years, education level of junior high school or below, sleep disorders, and low cardiac output.

Objective To enhance the mechanical properties of trichiral honeycomb sandwich structures and satisfy the design criteria for vertebral implant structures.Methods A chiral-like honeycomb sandwich structure with an auxiliary support structure was constructed for optimal design.The finite element method was used to study the influence of the auxiliary support structure on the chiral-like honeycomb sandwich structure and the relationship between the support position and mechanical property parameters.Furthermore,the influence of the deformation mechanism of different structures on mechanical properties was discussed.Results All chiral-like honeycomb sandwich structures exhibited enhanced mechanical properties in comparison to trichiral honeycomb sandwich structures.The mechanical properties of the chiral-like dCW honeycomb sandwich structure with the auxiliary support structure positioned perpendicular to the ligament were optimal,and this position represented the optimal support position.When the volume was used as a control variable,the compressive stiffness,stiffness-to-mass ratio,and transverse strain of the chiral-like honeycomb sandwich structure in the x1 direction were significantly correlated with the change of the support position,and all of them were positively correlated.Conclusions As a novel chiral-like honeycomb structure,it provides a biomechanical basis for the optimal design and clinical application of honeycomb sandwich structures as vertebral implant structures.
