Objective: To examine the association between academic stress and anxiety-depression comorbidity among college students and the potential moderating effect of physical activity, so as to provide a theoretical basis for the development of evidence based mental health promotion frameworks in higher education institutions. Methods: From October 2022 to June 2024, a total of 7 980 students from 21 universities across five provinces/municipalities in China, including Shanghai, Jiangsu, Zhejiang, Shandong, and Anhui, using a combination of convenience sampling and stratified random cluster sampling. Physical activity, academic stress, anxiety, and depression were assessed by using the 24 hour Movement Behaviors Questionnaire, the Chinese College Students Mental Health Screening Scale, the Generalized Anxiety Disorder-7, and the Center for Epidemiologic Studies Depression Scale, respectively. Binary Logistic regression was used to examine the associations between academic stress and anxiety, depression, and their comorbidity. The PROCESS macro was employed to test the moderating effect of physical activity. Results: The prevalence of anxiety-depression comorbidity among college students was relatively high (11.53%), with significant differences observed across grades and body mass index (BMI) categories ( χ 2=70.30, 24.63, both P <0.01). Binary Logistic regression revealed that, compared with low academic stress, moderate academic stress among male students was significantly associated with greater odds of anxiety ( OR =2.78), depression ( OR =2.75), and anxiety-depression comorbidity ( OR =2.89) (all P <0.01). High academic stress was associated with elevated odds of anxiety ( OR =6.66), depression ( OR =12.81), and anxiety-depression comorbidity ( OR =13.65) (all P <0.01). Among female students, moderate academic stress was associated with anxiety ( OR =2.58), depression ( OR =1.52), and anxiety-depression comorbidity ( OR =1.70) (all P <0.01). High academic stress increased the risk of anxiety ( OR =6.77), depression ( OR =6.81), and anxiety-depression comorbidity ( OR =7.48) (all P <0.05). The moderation analysis indicated that the interaction between total physical activity duration and academic stress had a significant netative moderating effect on anxiety-depression comorbidity among college students ( β =-0.03, P <0.01). Conclusions Academic stress increases the risk of anxiety, depression, and anxiety-depression comorbidity among college students. Physical activity may attenuate the adverse effects of academic stress on anxiety-depression comorbidity.

Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective To observe the efficacy and safety of 3 D video-assisted thoracoscopic segmentectomy in patients with stage Ⅰ lung cancer treated with indocyanine green(ICG)fluorescence reverse-staining.Methods A total of 132 patients with stage Ⅰ lung cancer who were admitted from May 2022 to September 2024 all underwent three-dimensional video-assisted thoracoscopic segmental resection of the lung.They were divided into the observation group(63 cases)and the control group(69 cases)according to the method of intersegmental plane exposure.The control group was treated with the modified expansion and collapse method,while the observation group was treated with the ICG fluorescence backstaining method.The surgical conditions,pulmonary function,postoperative pain degree,quality of life and complications of the two groups were compared.Results The postoperative chest tube retention time,surgical time,postoperative hospitalization time,total postoperative thoracic drainage volume,and inter-segmental plane exposure time in the observation group were as follows(2.13±0.37)d,(145.12±25.26)min,(5.21±0.95)d,(261.41±28.57)ml and(9.15±1.73)s,respectively.The data of the control groups were(3.29±0.48)d,(178.31±30.45)min,(6.34±1.36)d,(352.03±36.74)ml and(1 651.28±179.84)s,respectively.There was a statistically significant difference between the two groups(P＜0.05).There was no statistically significant difference in the number of intraoperative blood loss and intraoperative lymph node dissections between the two groups(P＞0.05).There was no statistically significant difference in the levels of maximal expiratory flow(PEF),forced expiratory volume in one second(FEV1),and FEV1/forced vital capacity(FVC)between the two groups before the operation and one month after the operation(P＞0.05).The Visual Analogue Scale(VAS)scores of the observation group at 12 hours,48 hours and 72 hours after the operation were(3.25±0.46)points,(2.13±0.35)points and(1.02±0.24)points respectively.The control groups were(4.11±0.59)points,(2.98±0.42)points,and(1.73±0.30)points,respectively.There was a statistically significant difference between the two groups(P＜0.05).There was no statistically significant difference in the scores of negative and positive items between the two groups before the operation and one month after the operation(P＞0.05).There was no statistically significant difference in the total incidence of complications between the two groups(P＞0.05).Conclusion The modified dilatation collapse method and ICG fluorescence reverse staining method have no significant effects on lung function and complications in patients with stage Ⅰ lung cancer,and both can improve the quality of life.Compared with the modified dilatation collapse method,ICG fluorescence reverse staining method can shorten the plane exposure time between segments and the operation time,promote postoperative rehabilitation and alleviate postoperative pain.

Objective:To investigate the impact of virtual navigation bronchoscopy on perioperative information in patients undergoing thoracoscopic pulmonary resection.Methods:Employed three distinct propensity score matching models to effectively address the baseline data disparities among patients undergoing thoracoscopic pulmonary resection. Categorized the patients into two groups: pulmonary wedge resection and pulmonary segmentectomy. Compared the disparities in clinical characteristics, intraoperative lesion resection, and postoperative recovery between patients who underwent virtual navigation bronchoscopy assisted localization prior to surgery and those who did not employ any specific localization methods.Results:This reserch included a total of 127 patients who underwent localization assisted by virtual navigation bronchoscopy, and 122 patients who did not undergo specialized localization. After propensity score matching, the navigation group demonstrated a statistically significant reduction in intraoperative blood loss[model 3, 40(20, 50) ml vs. 50(20, 100) ml, P=0.027], drainage volume on the first day post-surgery[model 3, 100(50, 175) ml vs. 150(100, 220) ml, P=0.023], and incidence of residual pleural effusion(model 3, 31 cases vs. 38 cases, P=0.046) compared to the non-positioning group among patients undergoing pulmonary wedge resection. In the pulmonary segmentectomy group, we observed a reduction in intraoperative blood loss[model 3, 50(30, 100) ml vs. 100(50, 100) ml, P=0.003] and incidence of residual pneumothorax(model 3, 18 cases vs. 28 cases, P=0.012) in patients who underwent navigation-assisted procedures compared to those without specialized positioning. Conclusion:The utilization of virtual navigation bronchoscopy for preoperative localization assistance in thoracoscopic sublobectomy(including wedge resection and segmental resection) may represent a viable approach to mitigate intraoperative injury and facilitate postoperative recovery.

Objective To screen and verify the genes that play key role in the occurrence and development of esophageal cancer by u-sing bioinformatics and real-time fluorescence quantitative PCR(qRT-PCR)methods to find new markers for diagnosis of esophageal cancer(ESCA).Methods Using the TCGA database and Wayne plot analysis,the cross genes between the differentially expressed genes of ESCA and the genes which have the most significant impacts on disease-free survival(DFS)rate in esophageal cancer patients were preliminarily identified.Following conducting protein-protein interaction(PPI)network analysis on the overlapping genes,GO and KEGG functional analysis was performed to screen the potential key genes as the diagnostic markers of esophageal cancer.qRT-PCR was used to quantitatively analyze the expression of mRNA of the key gene in peripheral blood.Statistical analysis was con-ducted based on the clinico-pathological characteristics of the patients to determine its potential value as a new diagnostic marker for e-sophageal cancer.Results After overlapping of differentially expressed genes of ESCA and disease-free survival genes in the TCGA database,39 upregulated genes and 20 downregulated genes were found to be differentially expressed,all of which affected disease-free survival rate.After conducting PPI network analysis,15 upregulated genes with core interactions were identified,and the downregulat-ed genes did not form any interaction network.Further enrichment analysis of these 15 core interacting genes through GO and KEGG,revealed that fibronectin 1(FN1)may be a potential biomarker for ESCA diagnosis.The qRT-PCR results showed that compared with the healthy control group,the mRNA expression level of FN1 in the peripheral blood of esophageal cancer patients was significantly ele-vated.After analyzing the clinical characteristics of patients,it was found that the patients with poor differentiation and high clinico-pathological staging had significantly increased peripheral blood FN1 mRNA levels.The model with FN1 mRNA expression levels can distinguish esophageal cancer patients from healthy individuals.Conclusion FN1 mRNA may be a potential non-invasive diagnostic biomarker for esophageal cancer.

Objective:To investigate the diagnosis and differential diagnosis methods of chronic mature small B-cell lymphoma involving the bone marrow and peripheral blood.Methods:The clinical data of 27 patients with mature small B-cell lymphoma involving the bone marrow and peripheral blood (seven subtypes phase IV) who received treatment in the Kunshan Third People's Hospital from February 2015 to June 2021 were retrospectively analyzed. The application value of different detection methods in the diagnosis of mature small B-cell lymphoma involving the bone marrow and peripheral blood was analyzed.Results:The majority of patients' peripheral blood was mainly characterized by an increase in the ratio or absolute value of lymphocytes. In terms of cell morphology, mature lymphocytes were mainly small to medium in size. A few bone marrow smears or peripheral blood smears show characteristic changes in cell morphology. Flow cytometry results showed that among the cohort of 15 patients presenting CD5 expression, 11 patients had chronic lymphocytic leukemia, 1 patient had mantle cell lymphoma, 1 patient had splenic diffuse red pulp small B-cell lymphoma, and 2 patients had B-cell chronic lymphoproliferative disorders (unclassified). Among 12 patients presenting no CD5 expression, 8 had Waldenstr?m's macroglobulinemia, 3 had splenic marginal zone lymphoma, and 1 had follicular lymphoma. Among the 2 patients presenting CD5-CD10 expression, 1 patient had follicular lymphoma, and 1 patient had Waldenstr?m's macroglobulinemia. One patient with splenic diffuse red pulp small B-cell lymphoma expressed CD5, CD11c, and CD103 in addition to pan-B-cell markers, while BRAF V600E mutation detection and immunohistochemical staining for tartrate-resistant acid phosphatase and annexin-1A showed negative expression.Conclusion:This type of lymphoproliferative disease is a general term for lymphoma that has various different molecular and biological characteristics. Its diagnosis and differential diagnosis need to comprehensively consider the clinical characteristics of the patient, relevant laboratory tests, cell morphology, flow cytometry detection results, reasonable use of fluorescence in situ hybridization, molecular biology, special chemistry, and bone marrow immunohistochemistry. In a few cases, diagnosis of the lymphoproliferative disease still relies on non-bone marrow involvement and tissue biopsy.

Inflammatory caspase-11 senses and is activated by intracellular lipopolysaccharide (LPS) leading to pyroptosis that has critical role in defensing against bacterial infection, whereas its excess activation under pathogenic circumstances may cause various inflammatory diseases. However, there are few known drugs that can control caspase-11 activation. We report here that scutellarin, a flavonoid from Erigeron breviscapus, acted as an inhibitor for caspase-11 activation in macrophages. Scutellarin dose-dependently inhibited intracellular LPS-induced release of caspase-11p26 (indicative of caspase-11 activation) and generation of N-terminal fragment of gasdermin D (GSDMD-NT), leading to reduced pyroptosis. It also suppressed the activation of non-canonical nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome as evidenced by reduced apoptosis-associated speck-like protein containing a CARD (ASC) speck formation and decreased interleukin-1 beta (IL-1β) and caspase-1p10 secretion, whereas the NLRP3-specific inhibitor MCC950 only inhibited IL-1β and caspase-1p10 release and ASC speck formation but not pyroptosis. Scutellarin also suppressed LPS-induced caspase-11 activation and pyroptosis in RAW 264.7 cells lacking ASC expression. Moreover, scutellarin treatment increased Ser/Thr phosphorylation of caspase-11 at protein kinase A (PKA)-specific sites, and its inhibitory action on caspase-11 activation was largely abrogated by PKA inhibitor H89 or by adenylyl cyclase inhibitor MDL12330A. Collectively, our data indicate that scutellarin inhibited caspase-11 activation and pyroptosis in macrophages at least partly via regulating the PKA signaling pathway.

Drug-associated reward memories are conducive to intense craving and often trigger relapse. Simvastatin has been shown to regulate lipids that are involved in memory formation but its influence on other cognitive processes is elusive. Here, we used a mass spectrometry-based lipidomic method to evaluate the impact of simvastatin on the mouse brain in a cocaine-induced reinstatement paradigm. We found that simvastatin blocked the reinstatement of cocaine-induced conditioned place preference (CPP) without affecting CPP acquisition. Specifically, only simvastatin administered during extinction prevented cocaine-primed reinstatement. Global lipidome analysis showed that the nucleus accumbens was the region with the greatest degree of change caused by simvastatin. The metabolism of fatty-acids, phospholipids, and triacylglycerol was profoundly affected. Simvastatin reversed most of the effects on phospholipids induced by cocaine. The correlation matrix showed that cocaine and simvastatin significantly reshaped the lipid metabolic pathways in specific brain regions. Furthermore, simvastatin almost reversed all changes in the fatty acyl profile and unsaturation caused by cocaine. In summary, pre-extinction treatment with simvastatin facilitates cocaine extinction and prevents cocaine relapse with brain lipidome remodeling.
