Objective: To explore the relationship between non suicidal self injury (NSSI) behavior and serum lipid levels as well as thyroid function among college students with depression. Methods: A total of 169 college students with depression in the psychiatry departments of tertiary hospitals (grade 3A and 3B) in Ningbo from December 2023 to April 2025 were selected. The Adolescent Self injury Scale (ASIS) was used to assess the presence of NSSI, and participants were accordingly divided into a NSSI group ( n =51) and a non NSSI group ( n =118). General demographic data (including gender, age, and family situation) were collected from both groups. Blood tests were performed to measure lipid profiles [triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)] and thyroid hormones [triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH)]. Multivariate Logistic regression was employed to analyze risk factors for NSSI, and receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of serum lipid and thyroid hormone levels for NSSI occurrence in college students with depression. Results: The levels of TC, LDL-C, and TSH in the NSSI group were (4.02±0.73) mmol/L, (2.32±0.36) mmol/L, and (6.57±1.95) mU/L , which were significantly higher than those in the non NSSI group [(3.41±0.56) mmol/L, (2.00±0.27) mmol/L, and ( 4.48± 1.09) mU/L, respectively] ( t =5.32, 5.60, 7.20, all P <0.05). Logistic regression analysis revealed that college students from single parent/reconstituted families, those who had experienced school bullying, and those with higher levels of TC, LDL-C, and TSH had a significantly increased risk of engaging in NSSI ( OR =5.22, 6.12, 5.90, 83.64, 3.64, all P <0.05). ROC curve analysis demonstrated that the combined detection of TC, LDL-C, and TSH had high diagnostic efficacy for predicting NSSI in college students with depression, with a sensitivity of 86.3% and a specificity of 94.9%. Conclusions NSSI behavior in college students with depression is associated with serum lipid levels and thyroid function. These biomarkers may serve as useful reference indicators for assessing the conditions of these patients.

Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

AIM:To study the effect of Sanhuang Gel on the expression of TLRs/NLRP3 signal path-way in auricle acne model rats,and to explore its mechanism in treating acne inflammatory injury.METHODS:A rat model of auricular acne was in-duced by applying 100％oleic acid to the opening of the right ear catheter and injecting Propionibac-terium acnes.Rats were divided into normal group,model group,positive control group(clindamycin hydrochloride gel 10 mg/g)and Sanhuang Gel high,medium and low dose groups(280,140 and 70 mg/g).Each drug group was given drug intervention for 28 days.The changes of auricle skin lesions in each group were observed;Hematoxylin-eosin(HE)staining was used to observe the pathological changes of auricle acne.The ultrastructural chang-es of auricle tissue cells were observed by transmis-sion electron microscope(TEM).The distribution and expression changes of TLR2 and TLR4 in rat au-ricle tissue were detected by immunofluorescence.The expressions of TLR2,TLR4,NLRP3,ASC and Cas-pase-1 mRNA in rat auricle were detected by Real-time PCR.The expressions of TLR2,TLR4,NLRP3,ASC and Caspase-1 in rat auricle were detected by Western blot.RESULTS:Compared with the normal group,papules,pustules,inflammatory cell infiltra-tion and obvious edema of mitochondria can be seen in the auricle tissue of the model group.The mRNA and protein expression levels of TLR2,TLR4,NLRP3,ASC andCaspase-1 increased significantly(P＜0.01).Compared with the model group,the ap-pearance and pathological damage of auricle in each treatment group were obviously alleviated,and the morphology and structure of mitochondria returned to normal.The mRNA expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 decreased significantly(P＜0.01).The expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 in positive control group and high and middle dose groups de-creased(P＜0.01,P＜0.05).The expression levels of ASC and Caspase-1 protein in low dose group were significantly decreased(P＜0.01),but there was no significant difference in the expression levels of TLR2,TLR4 and NLRP3 protein(P＞0.05).CONCLU-SION:Sanhuang Gel can improve the pathological damage of auricle tissue and reduce immune in-flammatory reaction in acne rats,and its mecha-nism may be related to regulating TLRs/NLRP3 sig-naling pathway.

Objective:To explore the healing effects of internal heat needle and electroacupuncture on post-stroke shoulder pain and their impacts on serum interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α).Methods:From January 2023 to March 2025, 94 patients with post-stroke shoulder pain admitted to the Affiliated Hospital of Hangzhou Normal University were included and separated into two groups according to a random number table. The 47 cases in the electroacupuncture group adopted electroacupuncture, while 47 cases in the internal heat needle group adopted internal heat needle. The pre- and post-treatment limb function, quality of life, healing effect, visual analogue scale (VAS), and serum IL-6, IL-1β, and TNF-α were compared.Results:After treatment, the Constant-Murley Shoulder Scale (CMS) score, shoulder range of motion (flexion, outward rotation, extension), Fugl-Meyer Assessment-Upper Extremity (FMA-UE) score, and Modified Barthel Index (MBI) in the internal heat acupuncture group were all better than those in the electroacupuncture group:(63.45 ± 10.31) points vs. (56.51 ± 9.15) points, (136.67 ± 32.44)° vs. (109.32 ± 25.01)°, (51.64 ± 12.84)° vs. (42.95 ± 11.72)°, (34.35 ± 10.15)° vs. (29.53 ± 9.82)°, (45.63 ± 10.25) points vs. (39.16 ± 10.43) points, (83.42 ± 16.09) points vs. (74.55 ± 15.83) points, there were statistical differences ( P<0.05). While the levels of serum IL-1β, IL-6, TNF-α, and VAS score in the internal heat needle group were decreased in the electroacupuncture group: (7.39 ± 3.68) ng/L vs. (9.28 ± 4.10) ng/L, (19.25 ± 2.12) ng/L vs. (28.50 ± 2.43) ng/L, (9.55 ± 3.54) ng/L vs. (11.17 ± 3.77) ng/L,(1.69 ± 0.45) points vs. (2.13 ± 0.56) points, there were statistical differences ( P<0.05). The therapeutic effect in the internal heat needle group was significantly higher than that in the electroacupuncture group:93.62% (44/47) vs. 78.72% (37/47), there was statistical difference ( P<0.05). Conclusions:For post-stroke shoulder pain, internal heat needle therapy has a clear healing effect than electroacupuncture, and can effectively reduce the levels of inflammatory factors such as IL-1β, IL-6, and TNF-α in serum.

BACKGROUND:Previously,a SENP1 gene-silenced human alveolar epithelial cell line was successfully constructed in vitro,and the role of SENP1 in hyperoxic lung injury was investigated at the cellular level.OBJECTIVE:To construct a mouse model of alveolar type II epithelial cell-specific knockout of SENP1 gene based on the Cre-loxP recombinase system.METHODS:SENP1flox/-mice were self-crossed to obtain SENP1flox/flox and SENP1flox/-mice;Sftpc-Cre+/+mice were crossed with wild-type mice to obtain more Sftpc-Cre+/-mice.Sftpc-Cre+/+or offspring Sftpc-Cre+/-mice were crossed with SENP1flox/-or offspring SENP1flox/flox mice to obtain SENP1flox/-Sftpc-Cre+/-double heterozygous mice.SENP1flox/-Sftpc-Cre+/-mice were then crossed with SENP1flox/flox mice to obtain SENP1flox/floxSftpc-Cre+/-mice.The genomic DNA was extracted by tail clipping and amplified by PCR.The amplified product was subjected to agarose gel electrophoresis to determine the mouse genotypes.Lung tissues of SENP1flox/flox and SENP1flox/floxSftpc-Cre+/-mice were subjected to immunofluorescence double-labelling and western blot assay to verify the knockdown effect of SENP1 gene.Heart,liver,lung and kidney tissues of SENP1flox/flox and SENP1flox/floxSftpc-Cre+/-mice were stained with hematoxylin-eosin to observe the histomorphology of each organ in the two groups of mice.RESULTS AND CONCLUSION:SENP1flox/floxSftpc-Cre+/-mice were correctly screened by agarose gel electrophoresis.Immunofluorescence double-labeling experiments showed that the mean fluorescence intensity of SENP1 was reduced in lung tissues of SENP1flox/floxSftpc-Cre+/-mice compared with that of SENP1flox/flox mice(P<0.01)and no significant co-localization of SENP1 and Sftpc was observed(P<0.01).Western blot results showed that SENP1 protein expression was reduced in lung tissues of SENP1flox/floxSftpc-Cre+/-mice compared with SENP1flox/flox mice(P<0.001).Hematoxylin-eosin staining showed no significant alterations in the histomorphology of heart,liver,lung and kidney tissues in SENP1flox/flox and SENP1flox/floxSftpc-Cre+/-mice.This study successfully constructed alveolar type II epithelial cell-specific knockout SENP1 gene mice using the Cre-loxP recombinase system,which provides a good tool for the subsequent study of the role of SENP1 gene in lung diseases such as bronchopulmonary dysplasia and idiopathic pulmonary fibrosis,in which alveolar type II epithelial cells are the main damage cells.

Objective To analyze the relationship between post-traumatic growth(PTG)and health-related quality of life(HRQOL)among long-term cancer survivors(time since diagnosis≥5 years)and to explore the trends and reasons for changes over time.Methods A total sampling method was used to conduct baseline and follow-up surveys on long-term cancer survivors from 6 cancer registries in Germany during 2008-2011 and 2018-2019.General information questionnaires,Post-Traumatic Growth Inventory,and European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire were applied.The collected data were analyzed using a linear mixed-effects regression model for longitudinal relationships.Results A total of 2704 long-term cancer survivors completed the baseline and follow-up surveys and the effective sample size is 2 686.The high PTG group had a significantly higher overall health status/QOL score than the low PTG group,with a statistically significant difference(P＜0.05).However,the difference in scores between the 2 groups at follow-up was not statistically significant(P＞0.05).The interaction between PTG groups and time was statistically significant for overall health status and insomnia(all P＜0.05).There was a stable positive relationship between PTG and economic difficulty scores with a statistically significant difference(P＜0.001).Conclusion There is a positive correlation between PTG and HRQOL among long-term cancer survivors that weakens over time,and the perceived economic burden related to health is a continuous source of stress.

Objective To investigate the CT and MRI features of giant cell reparative granuloma(GCRG)in lateral skull base.Methods The CT,MRI and clinicopathological data of 8 patients with GCRG in lateral skull base were collected and analyzed.Results All of the eight lesions were unilateral and solitary(three on the left side and five on the right side),with widespread involvement affecting two or more bony structures of the lateral skull base.All lesions showed expansile and lytic bone destruction on CT scans,the margins were clear(7/8),and the sclerotic changes could be seen at the margin of all eight lesions.On MRI,the lesions revealed heterogeneous isointense and hypointense on T1WI,and heterogeneous hypointense with focal cystic changes on T2WI,without fluid-fluid levels.The enhanced scan showed heterogeneous enhancement.Seven cases extended to the middle cranial fossa,caused com-pression of the temporal lobe brain tissue,with thickened and strengthened adjacent meninges.Conclusion The GCRG in lateral skull base has certain characteristic appearances on CT and MRI;understanding these characteristic manifestations can provide a basis for accurate diagnosis.

Objective To investigate the value of carotid ultrasonographic lesion indices in predicting coronary artery stenosis in patients with essential hypertension,and to analyze their correlation with the degree of coronary artery stenosis.Methods A total of 4 691 patients diagnosed with essential hypertension who visited our cardiac center between January 2020 and September 2023 were included in this study.All the patients underwent carotid ultrasound exam and coronary angiography.Their baseline clinical data were collected,and the severity of coronary artery stenosis was quantified using the Gensini score.Carotid ultrasound parameters,including resistance index(RI),pulsatility index(PI),intima-media thickness(IMT),intimal thickening,plaque formation and luminal stenosis,were evaluated in detail.To control for potential confounders,six multivariate Logistic regression models were constructed to analyze the stratified data on carotid artery lesions.Results Pearson correlation analysis revealed significant positive correlations of PI,RI and IMT with the Gensini score of coronary artery stenosis in hypertensive patients(left PI:r=0.041,P=0.005;right PI:r=0.035,P=0.017;left RI:r=0.119,P＜0.001;right RI:r=0.032,P=0.027;IMT:r=0.043,P=0.003).Multivariate Logistic regression analysis indicated that carotid plaque formation and stenosis were significantly associated with an increased risk of coronary artery disease(CAD)in hypertensive patients(P＜0.001),while intimal thickening was associated with a significantly decreased risk of CAD(P=0.009).Model 2 adjusted for sex,age,educational level,smoking history,systolic blood pressure,and other variables,while Model 3 further adjusted for blood parameters,including white blood cell count,creatinine,and lipid profiles.Stratified analysis of carotid artery lesions showed that intimal thickening combined with plaque formation(Model 5)and plaque formation combined with stenosis(Model 6)were significantly associated with an increased risk of CAD(P＜0.001).In contrast,the difference in patients with only intimal thickening(Model 4)was not statistically significant(P=0.127).Conclusion Carotid ultrasound lesion characteristics are strongly associated with the risk of coronary artery stenosis in patients with essential hypertension,and carotid artery lesions can be used as a useful tool to assess the risk of coronary artery disease in hypertensive patients.
