Objective: To investigate the association between the physical fitness index (PFI) and symptoms of depressive, anxiety and stress symptoms among college students, providing a reference for mental health interventions. Methods: From June to September 2025, combined convenience and cluster random sampling approach was used to administer questionnaire surveys and perform physical fitness tests on 2 712 college students from Zhejiang Chinese Medical University. The Depression Anxiety Stress Scales-21 Items (DASS-21) was used to assess mental health status. Chi square test and multivariate Logistic regression analysis were used to determine the associations between the PFI and the PFI component indicators with depressive, anxiety and stress symptoms. Results: The prevalence of depressive, anxiety and stress among college students were 24.26%, 33.22% and 13.68%, respectively. Statistically significant differences in the prevalence of these symptoms were detected across groups differing in sleep quality, physical activity, weekly breakfast frequency, and history of low back or neck pain ( χ 2=9.33-151.83, all P <0.05). After adjusting for confounding factors, Logistic regression revealed that the moderate and high PFI groups had significantly reduced risks of depressive and anxiety compared to the low PFI group ( OR =0.73, 0.63; 0.61, 0.72, all P <0.05). Poor speed (50 m run) and lower body strength (standing long jump) emerged as common risk factors affecting anxiety and depressive symptoms in both male and female college students (all P <0.05). Increased muscle strength (sit up for 1 min) in female students reduced the risk of depressive ( OR =0.81), anxiety ( OR =0.85), and stress symptoms ( OR =0.79) (all P <0.05). Enhanced lung capacity in male students decreased the risk of depressive ( OR =0.84) and anxiety symptoms ( OR =0.85) (both P <0.05). Conclusions The PFI is negatively correlated with depressive and anxiety symptoms among college students with notable gender differences. Insufficient speed and lower body explosive power represent common risk factors for mental health among male and female college students.

Objective To investigate the high-risk factors associated with acute postoperative hypertension (APH) following laparoscopic sleeve gastrectomy(LSG) in obese patients and to establish a predictive model. Methods A retrospective analysis was conducted on clinical data and laboratory parameters of obese patients who underwent LSG at Department of Metabolic Surgery in our hospital from August 2021 to December 2023. Logistic-LASSO regression analysis was used to identify independent risk factors for APH. A nomogram predictive model was developed based on these factors. The predictive performance and clinical utility of the model were assessed using the receiver operating characteristic (ROC) curve, Bootstrap resampling, calibration curve, Hosmer-Lemeshow (H-L) test, decision curve analysis (DCA), and clinical impact curve (CIC). Results The incidence of APH was 55.90%. Body mass index (BMI), platelet count, globulin, uric acid, sodium, fibrinogen, fasting blood glucose, and preoperative diastolic pressure had potential predictive value. Among them, BMI (OR=1.066, 95% CI: 1.003-1.137, P=0.046), platelet count (OR=0.994, 95% CI: 0.998-0.999, P=0.027), fibrinogen (OR=1.943, 95% CI: 1.128-3.479, P=0.02), and preoperative diastolic blood pressure (OR=0.953, 95% CI: 0.918-0.985, P = 0.006) were identified as independent high-risk factors. The area under the curve (AUC) of the nomogram was 0.783 (95% CI: 0.711-0.855), with a sensitivity of 0.817 and a specificity of 0.689. The AUC based on Bootstrap resampling was 0.776 (95% CI: 0.702-0.849). The H-L test yielded P>0.05, and the calibration curve showed good model fit. Both DCA and CIC demonstrated favorable screening efficiency. Conclusions BMI, platelet count, fibrinogen, and preoperative diastolic blood pressure are independent high-risk factors for APH following LSG. The developed nomogram model exhibits good predictive performance and clinical applicability, providing a valuable tool for early screening and prevention of APH in LSG patients.

Central memory T (Tcm) cells are a crucial subset in T cell development, playing an important role in long-term immune responses. Tcm cells exhibit strong proliferative capacity, long-term survival characteristics, and re-activation potential, enabling them to rapidly differentiate into effector T cells (Teff) upon antigen re-exposure, thus providing robust immune protection. The function of Tcm cells is regulated by various factors, including antigen exposure, cytokines, and metabolic conditions. A deeper understanding of their metabolic and epigenetic mechanisms under different pathological conditions will contribute to the development of more precise and effective immunotherapeutic strategies. This review elaborates on the origin and characteristics of Tcm cells, as well as their roles in antiviral responses, tumor immunity, and immunotherapy.

Objective To explore the molecular mechanism of luteolin in the treatment of cervical cancer based on network pharmacology and molecular docking technology. Methods The drug-like properties of luteolin were analyzed by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). The targets of luteolin were obtained from PharmMapper, Super-PRED, and Swiss Target Prediction databases. The targets related to cervical cancer were acquired from GeneCards, OMIM, and PharmGKB databases. The intersection targets of luteolin and cervical cancer were obtained through EVenn, and the "luteolin-intersection targets-cervical cancer" network diagram was constructed by Cytoscape 3.8.1. The STRING database was used to analyze the protein-protein interaction (PPI) network of intersection targets and screen the core targets. The Database for Annotation, Visualization and Integrated Discovery (David) was used to conduct Gene Ontology (GO) gene function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway enrichment analysis of the targets. PyMoL 2.6.0, AutoDockTool 1.5.7 and OpenBabel 2.4.1 software were used to perform molecular docking between the core targets and luteolin. The survival analysis and pan-cancer analysis of the core targets were performed in the GEPIA database. Results A total of 449 targets of luteolin and 1 334 targets related to cervical cancer were obtained; there were 100 intersection targets between luteolin and cervical cancer, of which 24 were core targets, including MMP2, HRAS, MAPK1, AKT1, RHOA and PGR. GO and KEGG enrichment analyses revealed that the intersection targets participated in 455 biological processes, 70 cellular components, 119 molecular functions, and 143 KEGG signaling pathways. Molecular docking revealed a good binding of MMP2 with luteolin. The survival curves of cervical cancer patients showed that the risk ratios of RHOA, MAPK1, MMP2 and AKT1 genes were greater than 1, while those of HRAS and PGR were less than 1. Pan-cancer analysis showed that HRAS and MAPK1 were highly expressed in cervical cancer, and HRAS had significant expression differences. Conclusion Luteolin treats cervical cancer through a multi-target and multi-pathway mechanism.

Objective:To compare the effectiveness and safety profile of centrifugal and membrane plasma separation model in artificial liver therapy with a dual plasma molecular adsorption system (DPMAS).Method:A retrospective study was conducted. Data of inpatients with liver failure who were treated with DPMAS therapy in the Liver Disease Center of Nanfang Hospital, Southern Medical University, from October 2022 to June 2024 were included. Clinical data such as demographic characteristics, etiology, DPMAS treatment-related indicators (including plasma separation method, vascular access, frequency of treatment, treatment duration, type of anticoagulant drugs, and membrane rupture condition), and laboratory test indicators before and after DPMAS treatment were collected. Categorical variables were compared by the χ2 test. Continuous variables were compared using a t-test or a non-parametric test between groups. Result:Data of 232 cases with liver failure who received artificial liver therapy with DPMAS were included. A total of 473 times DPMAS treatment was given. The average age was 50 years old, and males accounted for 82.3%. Centrifugal plasma separation was the initial DPMAS treatment in 176 (75.9%) cases, while membrane plasma separation was used in 56 cases (24.1%). The most common vascular access for DPMAS treatment was the internal jugular vein. The most commonly used anticoagulant was unfractionated heparin. The treatment duration of DPMAS was significantly higher with centrifugal separation than that with membrane separation ( P<0.001). Hemoglobin levels (mean before and after treatment in the centrifugal: 112.8 g/L vs. 106.3 g/L, P<0.001; mean before and after treatment in the membrane group: 108.4 g/L vs. 103.3 g/L, P<0.001), red blood cell count (mean before and after treatment in the centrifugal group: 3.7×10 9/L vs. 3.5×10 9/L, P<0.001; mean before and after treatment in the membrane group: 3.5×10 9/L vs. 3.3×10 9/L, P<0.001) and platelet count (mean before and after treatment in the centrifugal group: 134.5×10 9/L vs. 119.6×10 9/L, P<0.001; mean before and after treatment in the membrane group: 120.7 ×10 9/L vs. 97.3 ×10 9/L, P<0.001) were slightly decreased following initial DPMAS treatment in both groups. The decrease in platelets was significantly lower in centrifugal separation than that in membrane separation (median: 10.4% vs. 17.0%; P=0.003). There was no statistically significant difference observed in the proportion of puncture site bleeding in terms of plasma separation-related adverse events between the two groups, but plasma separator membrane rupture occurred two times in the DPMAS treatment. Conclusion:Centrifugal and membrane separation, both with DPMAS therapy, can cause a slight decrease in hemoglobin, red blood cell count, and platelets in patients with liver failure. Membrane separation causes a larger drop in platelets than centrifugal plasma separation. The operational convenience of medical personnel, the risk of membrane rupture, the coagulation markers, the patient's vascular condition, and other factors should be comprehensively considered when choosing the plasma separation model.
