Objective: To revise and validate the reliability and validity of Chinese version of the Benevolent Childhood Experiences (BCEs) Scale among college students, so as to provide a scientific and reliable assessment tool for related research. Methods: From April to June 2025, a stratified cluster random sampling method was used to select 1 677 freshmen from a university in Xuzhou City as participants. The survey was conducted by using the revised Benevolent Childhood Experiences (BCEs) Scale, Childhood Trauma Questionnaire (CTQ) and Brief Suicidal Behavior Scale. Reliability analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Spearman correlation analysis, and hierarchical linear regression analysis were employed to evaluate the scale s reliability, validity, and relationships among variables. Results: The mean scores of the 10 items on the BCEs Scale ranged from 3.97 to 4.46, with standard deviations ranging from 0.88 to 1.07. The Cronbach α coefficient was 0.96. Exploratory factor analysis extracted a single factor, explaining 71.21% of the total variance. Confirmatory factor analysis indicated good model fit ( χ 2/df =4.81, goodness of fit index=0.99, comparative fit index=0.99, normed fit index=0.99, root mean square error of approximation=0.05, standardized root mean square residual=0.01). BCEs total scores were negatively correlated with CTQ total scores and all its dimensions among college students ( r =-0.53 to -0.13, all P < 0.01). Hierarchical regression analysis showed that BCEs moderated the effect of CTQ on suicidal behavior, with a statistically significant interaction ( β=-0.11, t=-4.01, P <0.01). Conclusion The Chinese revised version of the BCEs Scale demonstrates good reliability and validity, and it is suitable for assessing BCEs among Chinese college students.

ObjectiveTo investigate the therapeutic mechanism of Danhe granules in treating mixed hyperlipidemia based on network pharmacology， as well as animal and cell experiments. MethodsThe active compounds and targets of Danhe granules were screened using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Encyclopedia of Traditional Chinese Medicine （ETCM）. Related targets for mixed hyperlipidemia were obtained from the GeneCards database. The intersecting targets were subjected to Gene Ontology （GO） functional annotation and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses. A high-fat model was established in human hepatocellular carcinoma cells （HepG2） induced by palmitic acid （PA）， followed by intervention with Danhe granules to assess intracellular lipid accumulation and oxidative stress levels. A mixed hyperlipidemia rat model was also established and divided into low-， medium-， and high-dose Danhe granules groups （1.134， 2.268， and 4.536 g·kg^-1， respectively）， as well as a positive control group treated with pravastatin sodium （4.020 mg·kg^-1）. After eight weeks of intervention， serum lipid levels， inflammatory factors， oxidative stress indices， and the expression of key hepatic lipid metabolism-related proteins were determined. ResultsNetwork pharmacology identified 93 intersecting targets between Danhe granules and mixed hyperlipidemia， with peroxisome proliferator-activated receptor gamma （PPARG）， peroxisome proliferator-activated receptor alpha （PPARA）， tumor necrosis factor （TNF）， interleukin-6 （IL-6）， and IL-1B among the key nodes. The PPAR signaling pathway， AGE/RAGE signaling pathway， lipid metabolism， atherosclerosis and non-alcoholic fatty liver disease （NAFLD） were among the most significantly enriched pathways. Cellular experiments demonstrated that Danhe granules significantly reduced reactive oxygen species （ROS） and malondialdehyde （MDA） levels while increasing catalase （CAT） activity （P<0.05）， thereby alleviating intracellular lipid accumulation and triglyceride （TG） content in HepG2. In animal experiments， Danhe granules markedly decreased serum total cholesterol （TC）， TG， and low-density lipoprotein cholesterol （LDL-C） levels （P<0.05）， reduced hepatic MDA levels， and elevated superoxide dismutase （SOD） and CAT levels. Histological analysis showed alleviation of hepatic steatosis， upregulation of hepatic PPARA and lipoprotein lipase （LPL） expressions， and downregulation of sterol regulatory element-binding protein 1 （SREBP1） expression （P<0.05， P<0.01）. ConclusionDanhe granules improve lipid metabolism disorders in mixed hyperlipidemia by reducing MDA levels， enhancing SOD and CAT activities， scavenging excessive ROS， inhibiting oxidative stress， and mitigating liver injury. The underlying mechanism may involve the upregulation of PPARA and LPL and the suppression of SREBP1 expression.

Objective: To examine the reciprocal relationships of anxiety and depressive symptoms,uncertainty stress with academic buoyancy among college students, providing evidence for mental health promotion and academic resilience enhancement. Methods: A multi stage cluster random sampling method was used to selected 741 undergraduates from grade 1 to 2 of a university in Xuzhou, Jiangsu Province. Participants completed two waves of surveys (T1: October 2022; T2: October 2023) using the Uncertainty Stress Scale, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Academic Buoyancy Scale. Cross lagged models analyzed bidirectional relationships between three mental health variables and academic buoyancy, followed by latent variable modeling integrating all mental health dimensions. Results: Cross lagged model results revealed that T1 uncertainty stress negatively predicted T2 academic buoyancy ( β =-0.14), while T1 academic buoyancy negatively predicted T2 uncertainty stress ( β =-0.11); T1 depressive symptom negatively predicted T2 academic buoyancy ( β =-0.08), while T1 academic buoyancy negatively predicted T2 depressive symptom ( β =-0.09); furthermore, T1 academic buoyancy negatively predicted T2 anxiety symptom( β =-0.10) ( P <0.05). Results from the latent variable cross lagged model of psychological problems (constructed from the three mental health variables) indicated that T1 psychological problems negatively predicted T2 academic buoyancy ( β =-0.09), while T1 academic buoyancy negatively predicted T2 psychological problems ( β =-0.09) ( P <0.05). Conclusions Longitudinal bidirectional relationships exist between mental health status and academic buoyancy in college students. Better mental health facilitates higher academic buoyancy.

Objective To explore the potential causal links between micronutrient levels and the risk of immune-mediated inflammatory skin disease(IMID).Methods Leveraging publicly accessible genome-wide association study(GWAS)datasets,fifteen specific micronutrients were identified as exposure variables,while four prevalent IMID:Psoriasis,atopic dermatitis,urticaria,and alopecia areata were designated as study outcomes.Robust instrumental variables were meticulously selected to facilitate the Mendelian randomization analysis.The main assessment used the inverse-variance weighting(IVW)method,complemented by an assortment of Mendelian randomization methodologies,inclusive of MR-Egger,weighted median estimate(WME)and weighted mode(WM).Rigorous sensitivity analyses were conducted to bolster the robustness of the findings.Results Vitamin D exhibited a significant inverse association with the risk of psoriasis(OR=0.996,P=0.001,95％CI:0.994-0.998),corroborated by consistent trends across WME,MR-Egger,and WM methods.Phosphorus demonstrated a positive correlation with urticaria risk(OR=5.634,95％CI:1.792-17.711,P=0.003),with findings in alignment with WME and WM methods.Copper was found to be positively associated with atopic dermatitis risk(ORIVW=1.234,P=0.0007,95％CI:1.092-1.394),and vitamin E levels were significantly related to the risk of urticaria(OR=26.643,P=0.013,95％CI:1.981-358.333).Sensitivity analysis did not show heterogeneity and pleiotropy(P＞0.05).Conclusion The study establishes a causal relationship between vitamin D levels and the risk of psoriasis,suggesting that augmenting vitamin D intake could be a viable dietary intervention for psoriasis prevention.These findings offer novel insights into the preventative and therapeutic strategies for IMID.

Objective To observe the clinical and CT findings of hepatic perivascular epithelioid cell tumor(PEComa)compared with liver cancer and liver adenoma.Methods Thirty patients with hepatic PEComa,31 patients with liver cancer and 31 patients with liver adenoma were retrospectively enrolled.Compared with liver cancer and liver adenoma,the clinical and CT findings of hepatic PEComa were observed.Results Significant differences of patients' gender,age and symptoms,also of the proportion of hepatitis,cirrhosis and positive alpha fetoprotein(AFP)were found between hepatic PEComa group and liver cancer group(all P＜0.05),while of patients' gender and age were found between hepatic PEComa group and liver adenoma group(both P＜0.05).Significant differences of the proportion of fat and malformed blood vessels,enhancement mode,as well as contrast enhancement ratio CER of arterial and venous phases were noticed between hepatic PEComa group and liver cancer group(all P＜0.05),while of the proportion of fat,capsule and malformed blood vessels,as well as enhancement mode and CER of arterial and venous phases were noticed between hepatic PEComa group and liver adenoma group(all P＜0.05).Conclusion Compared with liver cancer and liver adenoma,hepatic PEComa was mostly benign and more common in women,with somewhat characteristic CT findings being helpful to differential diagnosis.

Purpose To investigate the clinicopathological features and possible tumor-associated immune micro-environment in CD23-positive diffuse large B-cell lymphoma(DLBCL).Methods The clinicopathological data of 12 cases of CD23-positive DLBCL patients were analyzed retrospectively.The clinical and pathological features were ana-lyzed,and the clinical correlation and tumor-associated immune invasion were studied.Results CD23-positive DL-BCL accounted for 9.45％of all DLBCL.There were 6 males and 6 females.The mean age of onset was 64.83 years old.Four DLBCL cases occurred in lymph nodes and 8 cases occurred outside lymph nodes.Nine DLBCL cases were in advanced stage(Ⅲ-Ⅳ)and 3 cases DLBCL were in early stage(Ⅰ-Ⅱ).Among the patients,3 cases were untreated and lost to follow-up.One case deteriorated and died after operation.Two cases died,1 case progressed and 5 cases partially recovered after chemotherapy.Microscopically,the tumor cells were diffusely infiltrated and destroyed the nor-mal tissue structure.The tumor cells were observed to be centroblastic,immunoblastic and anaplastic large cells.No blastoid transformation and plasmacytoid differentiation were observed in morphology.According to Hans algorithm,11 cases were non-GCB phenotype except 1 case was GCB phenotype.Bioinformatics studies revealed that CD23 expres-sion was correlated with regulatory T cells,NK cells,plasma-like dendritic cells and neutrophils.Conclusion CD23-positive DLBCL patients are mainly middle-aged and elderly,and most of them occur outside lymph nodes and in ad-vanced stage(Ⅲ-Ⅳ).Follow-up results show that their prognosis is poor.Morphologically,there is no significant difference between DLBCL and conventional DLBCL.The Hans classification suggests that most cases originated from activated B cells.CD23 expression may play a role in the immune microenvironment of DLBCL.
