Objective:
To explore the latent profiles of psychological help seeking intentions among adolescents in Wuhan, and to investigate their association with non suicidal self injury (NSSI), in order to provide a theoretical basis for constructing an early intervention system for adolescents NSSI.
Methods:
From October to December 2022, a convenient sampling method was used to select 3 975 students from grades 7 to 12 in Wuhan. A self administered questionnaire assessed psychological help seeking intentions, followed by a post survey interview using the Ottawa Self injury Inventory to evaluate NSSI behaviors. Latent profile analysis(LPA) was used to explore the potential categories of help seeking intentions in adolescents. Multinomial Logistic regression was used to analyze factors associated with the latent profiles of help seeking intentions and multiple Logistic regression was used to analyze the association between latent profiles of help seeking intentions and NSSI.
Results:
Based on latent profile analysis, four latent profiles of help seeking intentions in adolescents were identified, namely overall low, moderate, and high help seeking group, as well as family/friendfocused help seeking group, accouting for 14.1%, 20.9%, 43.1% and 21.8%, respectively. Multinomial Logistic regression analysis showed that compared to senior high school students, junior high school students were more willing to seek help from family and friends ( OR =1.56); compared to males, females were more likely to exhibit moderate help seeking intentions( OR =1.37); students with extroverted or balanced personalities were more likely to exhibit high level help seeking intentions( OR =1.50, 1.49); students with average or good family economic status, better parental relationships, and adequate mental health knowledge were more likely to exhibit moderate and high level help seeking intentions( OR =1.59, 2.02; 1.80, 2.64; 1.44, 1.55; 1.34, 1.58) (all P <0.05). Students with moderate or severe family dysfunction were less likely to seek help from family and friends or to exhibit moderate and high level help seeking intentions( OR =0.51, 0.60, 0.25; 0.22, 0.27, 0.06, all P <0.01). Students whose parents exhibited stigma towards mental illness were less likely to show high level help seeking intentions( OR= 0.78 , P <0.05). Multivariable Logistic regression analysis results indicated that compared to the overall low help seeking intentions group, reduced risk of NSSI was observed among students in the overall moderate and overall high groups, as well as in the family/friend focused help seeking group( OR =0.73, 0.60, 0.70, all P <0.05).
Conclusions
Active psychological help seeking intentions can reduce NSSI behaviors in adolescents. Interventions should focus on improving family support environment to enhance adolescents intentions to seek psychological help.

ObjectiveTaking the cuproptosis/oxidative stress pathway as the entry point, this study investigated the effect and mechanism of Liangyi Paste on hepatic lipid deposition in naturally aged mice fed with a high-fat diet. MethodsAfter adaptive feeding, 80 ten-week-old male C57BL/6 mice were used. Thirty of them were randomly divided into three groups (10 mice per group): The 12-month-old control group (12MCON), the 15-month-old control group (15MCON), and the 15-month-old group with a high-fat diet (15MHFD). The 12MCON and 15MCON groups were continuously fed a standard diet, while the 15MHFD group started receiving a high-fat diet at 12 months of age. Tissue samples were collected at the corresponding time points for each group. The remaining 50 mice were randomly divided into five groups (10 mice per group): the 20-month-old control group (20MCON), the model group, and the low-, medium-, and high-dose Liangyi Paste groups (2.91 , 5.82 , 11.64 g·kg-1·d-1, respectively). The 20MCON group was continuously fed a standard diet, while the other groups started receiving a high-fat diet at 15 months of age. At 18 months of age, the Liangyi Paste groups were administered the corresponding doses of Liangyi Paste by gavage, while the 20MCON and model groups were given an equal volume of saline by gavage. After 8 weeks of continuous gavage (when the mice reached 20 months of age), tissue samples were collected. Hepatic TG levels were measured using assay kits; liver histology and lipid deposition were observed via hematoxylin-eosin (HE) and oil red O staining; reactive oxygen species (ROS) were detected by enzyme-linked immunosorbent assay (ELISA); Cu2+, superoxide dismutase (SOD), and malondialdehyde (MDA) levels were measured by colorimetry; mRNA and protein expression of genes related to cuproptosis and oxidative stress pathways were analyzed by Real-time polymerase chain reaction(Real-time PCR) and Wes automated protein expression system. ResultsCompared with 12MCON, the 15MCON group showed significantly increased hepatic TG, Cu2+, ROS, and MDA levels (P<0.01), decreased SOD (P<0.01), hepatocyte swelling, and disordered arrangement. The mRNA and protein levels of ferredoxin 1 (FDX1), dihydrolipoamide S-acetyltransferase (DLAT), heat shock protein 70 (HSP70), dihydrolipoamide dehydrogenase (DLD), pyruvate dehydrogenase E1 subunit-β (PDHB), nuclear factor erythroid 2-related factor 2 (Nrf2), and peroxisome proliferator-activated receptor γ (PPARγ) were significantly elevated (P<0.05, P<0.01). Compared with 15MCON group, the 15MHFD and 20MCON groups exhibited further increases in TG, Cu2+, ROS, and MDA (P<0.01), reduced SOD (P<0.01), and aggravated hepatocyte swelling and disorder. There were increased lipid droplets with mild vacuolization in the 15MHFD group, and no significant lipid deposition was observed in the 20MCON group. FDX1, DLAT, HSP70, DLD, PDHB, Nrf2, and PPARγ mRNA and protein levels were significantly increased (P<0.05, P<0.01). Compared with 20MCON group, the model group demonstrated markedly elevated TG, Cu2+, ROS, and MDA (P<0.01), reduced SOD (P<0.01), severe hepatic steatosis, and upregulated expression of FDX1, DLAT, HSP70, DLD, PDHB, Nrf2, and PPARγ mRNA and proteins (P<0.05, P<0.01). All abnormalities were significantly reversed after Liangyi Paste treatment. ConclusionLiangyi paste can ameliorate hepatic lipid deposition in naturally aged mice with a high-fat diet by modulating the cuproptosis/oxidative stress pathway.

OBJECTIVE To focus on the classic NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula (HQHF) inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis (MASH). METHODS RAW264.7 cells were divided into 5 groups: Control group (10% blank serum), Model group [10% blank serum+5 μg/mL lipopolysaccharide (LPS)], HQHF-L group (2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS), HQHF-M group (5% drug-containing serum+5% blank serum+5 μg/mL LPS), and HQHF-H group (10% drug-containing serum+5 μg/mL LPS). After 24 h of routine culture post-administration, cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy; localization and expression of gasdermin D-N (GSDMD-N) were observed by immunofluorescence. Interleukin-1β (IL-1β) and IL-18 contents in supernatants were detected by ELISA; mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group, the Model group showed typical pyroptotic morphology (cell membrane bulging and pore formation), increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane ( P <0.05), significantly increased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly up-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). Compared with the Model group, the HQHF-L, HQHF-M and HQHF-H groups showed improved pyroptotic morphology, reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N ( P <0.05), significantly decreased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly down-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis, and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

ObjectiveTo investigate the effects of Qizhujianwei granules (QZJW) on abnormal proliferation and malignant transformation of gastric mucosal cells in rats with gastric intraepithelial neoplasia (GIN) and to explore the related mechanisms. MethodsA total of 80 SPF male Wistar rats were used. A GIN rat model was established using a four-factor comprehensive method consisting of methylnitronitrosoguanidine (MNNG), ranitidine, irregular feeding patterns, and sodium salicylate. Except for the normal group, after successful modeling, the rats were randomly divided according to body weight into a model group, a Moluodan group (0.55 g·kg-1), and a QZJW group (7.34 g·kg-1), with 12 rats in each group. All groups were treated for 8 weeks. The general characteristics of the rats and morphological changes of the gastric mucosa were observed. Histopathological changes of the gastric mucosa were examined by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of pepsinogenⅠ (PGⅠ), pepsinogenⅡ (PGⅡ), and gastrin (G-17), as well as the expression level of transforming growth factor-β1 (TGF-β1) in gastric mucosal tissue, and the PGⅠ/PGⅡ ratio was calculated. Immunohistochemistry (IHC) was used to detect the localization and expression levels of proliferating cell nuclear antigen (Ki-67) and Vimentin in gastric mucosal tissue. Western blot analysis was used to determine the protein expression levels of Wnt family member 3A (Wnt3a), β-catenin, CyclinD1, proto-oncogene Cmyc, transforming growth factor-β receptor Ⅰ (TGFβRⅠ), intracellular signaling transducers Smad2/3, phosphorylated (p)-Smad2/3, twist family transcription factor (Twist1), and Vimentin in gastric mucosal tissue. ResultsCompared with the normal group, the model group showed characteristic changes including dim eyes, pale ears and claws, dark-red tongue, and reduced luster of the tail. The gastric mucosa appeared pale, with surface congestion and erosion. The gastric mucosal glands were disordered, the nuclear-to-cytoplasmic ratio increased, and local tumor cells were observed. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly decreased (P<0.01), while the level of G-17 was significantly increased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly increased (P<0.05, P<0.01), whereas the ratio of p-Smad2/3 to Smad2/3 was significantly decreased (P<0.05). Compared with the model group, the general characteristics and gastric mucosal conditions of rats in the Moluodan group and the QZJW group were improved. HE staining showed that QZJW could effectively block the malignant progression of GIN. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly increased (P<0.05, P<0.01), while the level of G-17 was significantly decreased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly decreased (P<0.05, P<0.01). ConclusionQZJW have a therapeutic effect on rats with GIN. The mechanism may involve inhibition of the Wnt/β-catenin signaling pathway to regulate the cell cycle and suppress abnormal cell proliferation. Meanwhile, it may inhibit epithelial-mesenchymal transition by suppressing the TGF-β1/Smad/Twist1 signaling pathway, thereby blocking the malignant progression of GIN.

Objective:
To investigate the prognostic significance and biological functions of neutrophil extracellular traps (NETs) related genes in oral squamous cell carcinoma (OSCC).
Methods:
A total of 333 transcriptome datasets and 6 single-cell sequencing datasets of OSCC were retrieved from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Based on 69 NETs related gene sets, univariate Cox and Lasso-Cox regression were used to construct a prognostic risk model for OSCC. The model's efficacy was evaluated through Kaplan-Meier analysis and receiver operating characteristic (ROC) curves, and risk scoring and nomogram analysis were conducted. Further, the relationship between NETs risk scores and angiogenesis, epithelial-mesenchymal transition (EMT), and cell cycle was explored. Enrichment analysis was performed to annotate the functional characteristics of relevant pathways. Kaplan-Meier analysis was employed to screen for prognostic key genes. Candidate targets were validated through drug prediction and molecular docking assays. Single-cell RNA sequencing was utilized to characterize the expression profile of the key gene cathepsin G (CTSG) within the tumor microenvironment (TME). Using pan-cancer and OSCC related data retrieved from the TCGA database, we analyzed the differences in CTSG expression between tumor tissues and normal tissues. Subsequently, immunohistochemical staining experiments were performed on tissue microarrays to validate its expression at the protein level.
Results:
A prognostic risk model based on six NETs related genes (F3, AKT1, CTSG, VNN3, MPO, and IL17A) was successfully established. Patients in the high-risk group exhibited significantly shorter overall survival (OS) (P < 0.000 1). The area under the ROC curve (AUC) of the established model for predicting 1-, 3-, and 5-year overall survival (OS) rates was 0.718, 0.820, and 0.805, respectively. The NETs related risk score was identified as an independent prognostic factor (P < 0.001), with the constructed nomogram demonstrating good calibration. The NETs related risk score correlated with angiogenesis (r = ˗0.20,, P < 0.001), EMT (r = 0.17, P < 0.01), G1/S phase transition (r = 0.11, P < 0.05), and G2/M phase transition (r = 0.17, P < 0.01). GSEA(gene set enrichment analysis)revealed that the high-risk group was significantly enriched in pathways including basal cell carcinoma, whereas the low-risk group exhibited significant enrichment in pathways such as alpha-linolenic acid metabolism (P < 0.05). Kaplan-Meier analysis revealed that patients with low expression of CTSG had a poorer prognosis (P < 0.001). Molecular docking assays demonstrated a stable binding interaction between CTSG and glutathione (binding energy: -7.4 kcal/mol). Single-cell RNA sequencing analysis further showed that CTSG was highly expressed in mast cell subsets but weakly expressed in malignant cells (P < 0.001). TCGA pan-cancer analysis revealed that CTSG is underexpressed in multiple cancer tissues, including OSCC (P < 0.05). Immunohistochemical staining confirmed that CTSG protein expression was lower in tumor tissues than in paracancerous tissues (P < 0.01).
Conclusion
The NETs related prognostic model established in this study exhibits robust predictive performance. CTSG was identified as a key prognostic gene, thereby providing a novel biomarker and potential therapeutic target for prognostic evaluation and targeted therapy of OSCC.

ObjectiveTo analyze the influencing factors of pulmonary dysfunction among community-based population at high-risk for chronic obstructive pulmonary disease (COPD), and to establish a risk assessment model to provide a reference basis for accelerating the beforehand prevention and control of COPD and promoting the respiratory health of community-based residents. MethodsIndividuals aged >35 years old, with at least one risk factor except age illustrated in the Guidelines for Primary Diagnosis and Treatment of Chronic Obstructive Lung Disease (2018), and participated in the early screening for COPD from July 2022 to December 2023 were selected as the research subjects, and their lung function was assessed by the forceful expiratory volume in the first second after inhalation of bronchodilator (FEV1)/ forced vital capacity (FVC) <70% and/or the ratio of FEV1 to predicted value (FEV1%Pred) <80% as the diagnostic criteria. In addition, risk factors related to pulmonary dysfunction were analyzed for the establishment of risk assessment model. ResultsA total of 823 individuals aged between 35‒76 years were included, among which 298 (36.21%) were diagnosed with pulmonary dysfunction, 167 (20.29%) with COPD, and 131 (15.92%) with preserved ratio but impaired spirometry. Logistic regression analysis revealed that male gender, increasing age, more frequent smoking, insufficient physical activity, recurrent wheezing, the presence of post-exercise wheezing or coughing, insensitive to airborne allergens, and history of chronic bronchitis or bronchial asthma were correlated with pulmonary dysfunction. The incidence rate of pulmonary dysfunction was 1.99 times higher in males than that in females, 1.81 times more common in those aged between 70‒76 years than those aged <60 years, 2.42 times more common in those who smoked 50‒200 pack-years than in those who smoked 0‒14 pack-years, 1.78 times higher in those who underwent physical activity <600 MET‑min·week-1 than in those who underwent physical activity ≥600 MET‑min·week-1, 2.61 times higher in those suffered recurrent wheezing than in those did not, 1.53 times higher in those with symptoms of post-exercise wheezing or coughing than in those without, 1.61 times higher in those insensitive to airborne allergens than those sensitive, 2.02 times higher in patients with chronic bronchitis than in those without, and 2.41 times higher in patients with bronchial asthma than in those without. The risk assessment model for pulmonary dysfunction constructed on this basis had a total score of 28 points, and the area under the subject operating characteristic (ROC) curve was 0.72, reaching the cut-off point of ROC curve while taking scores ≥10 points as the cut-off value for pulmonary dysfunction. ConclusionIn community-based high-risk COPD population, the incidence rate of pulmonary dysfunction is higher in males than that in females, in addition, which increases with the advancement of age. Smoking,insufficient physical activity,recurrent wheezing,post-exercise wheezing or coughing,insensitive to airborne allergens,and history of chronic bronchitis or bronchial asthma are high risk factors for pulmonary dysfunction. The risk assessment model constructed based on these factors has a good predictive effect in screening high-risk population of COPD, but its effectiveness in screening people at general risk needs to be further validated.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.
