Objective: To examine the association of sleep duration, physical activity, and their joint effects on depressive and anxiety symptoms among college students, and to provide evidence for the prevention and intervention of emotional symptoms in the population. Methods: From October to December 2023, a total of 7 684 college students aged 18-22 years, who were selected from nine universities in Hubei, Jiangxi, and Anhui provinces by using convenience sampling, underwent questionnaire surveys and physical examinations. Chi-square test and Logistic regression model were used to analyze the associations of meeting sleep duration and moderate to vigorous physical activity (MVPA) recommendations, as well as their joint effects, with depressive and anxiety symptoms. Results: The prevalence rates of depressive and anxiety symptoms were 25.78% and 35.59%, respectively. The prevalence rates of both depressive and anxiety symptoms differed significantly across sleep duration and physical activity groups ( χ 2= 9.32 -127.01, all P <0.01). Logistic regression analyses showed that insufficient sleep duration and failure to meet the physical activity recommendation were associated with higher odds of depressive symptoms ( OR =1.67, 1.20) and anxiety symptoms ( OR = 1.74 , 1.21 ) (all P <0.01). Further joint effects analyses showed that the combination of insufficient sleep and insufficient MVPA and that of insufficient sleep and sufficient MVPA were associated with higher odds of depressive symptoms ( OR =1.94, 1.38 ) and anxiety symptoms ( OR =2.09, 1.59) (all P <0.05). The combination of sufficient sleep and insufficient MVPA was also associated with higher odds of anxiety symptoms ( OR =1.16, P <0.05). Conclusions Sleep duration, physical activity, and their joint effects are associated with depressive and anxiety symptoms among college students. Joint interventions targeting both sleep and physical activity should be emphasized to reduce the risk of emotional symptoms.

Atherosclerosis and its complications are one of the diseases with the highest incidence and mortality in the world,and its early diagnosis and treatment are very important.At present,a variety of physiological and biochemical indicators have been used to diagnose atherosclerosis.However,the accuracy and ease of use of existing diagnostic indi-cators still cannot meet the clinical needs,and new,reliable and easy to measure biomarkers for early diagnosis and judg-ment of atherosclerosis and the risk of serious cardiovascular and cerebrovascular events caused by atherosclerosis are still very scarce.This article summarized the latest research progress of biomarkers related to atherosclerosis,such as hematol-ogy,genetics and omics,in order to provide basis for early diagnosis and treatment of atherosclerosis and related cardiovas-cular and cerebrovascular diseases induced by atherosclerosis.

Objective:To explore the optimal age cutoff for diagnosis and the prognosis of early-onset gastric cancer in young patients.Methods:Clinicopathological data of patients with gastric adenocarcinoma aged ≤45 years who had undergone radical gastrectomy in the Department of Gastric Surgery, Fudan University Shanghai Cancer Center from January 2013 to December 2018 were retrospectively collected. Patients with distant metastases, other malignant tumors, combined organ resection, gastric stump cancer, positive margin, and incomplete clinical or follow-up data were excluded. X-tile software analysis of the actual overall survival of the collected cases yielded an optimal cut-off of 32 years. Accordingly, the enrolled cases were divided into an early-onset young group (age ≤32 years) and young adult group (age >32 years). Clinicopathological characteristics, long-term survival, and postoperative recurrence were compared between the two groups. Univariate and multivariate analyses were performed using the Cox proportional hazards model to identify the factors affecting the prognosis of young patients with gastric cancer.Results:The study cohort comprised 462 patients, including 256 (55.4%) women, 419 (90.7%) with middle and lower gastric cancers, and 343 (74.2%) with poorly differentiated tumors. There were 101 patients in the early-onset young group and 361 in the young adult group. These groups did not differ significantly in terms of sex, body mass index, tumor location, tumor size, surgical procedure, neurovascular invasion, or tumor stage (all P>0.05). The proportion of patients with poorly differentiated tumors in the early-onset young group was significantly higher than that in the young adult group (89.1%[90/101] vs. 70.1%[253/361], χ 2=15.26, P<0.001). All study patients completed 5 years of follow-up, the median duration of which was 101 months (61-133 months). Death or tumor recurrence occurred in 151 patients (32.7%), in 118 of whom the sites of recurrence and metastasis could be identified, 38 in the early-onset young group and 80 in the young adult group. Fifty-five (46.6%) patients developed peritoneal metastases and 40 (33.9%) hematogenous metastases. In the early-onset young group, 20 patients developed peritoneal metastases, 11 hematogenous metastases, five distant lymph node metastases, and two local recurrence. In the young adult group, 35 patients developed peritoneal metastases, 29 hematogenous metastases, six local recurrences, and 10 distant lymph node metastases. The 5-year overall survival and disease-free survival rates were significantly higher in the young adult group than in the early-onset young group (73.7% vs. 57.4%, P=0.002 and 70.6% vs. 55.4%, P=0.004, respectively). Cox multivariate analysis showed that age >32 years (HR=0.63, 95%CI: 0.43-0.90, P=0.012) was an independent protective factor for overall survival, whereas later N stage (HR=1.67, 95%CI:1.09-2.57, P=0.018) was an independent risk factor for overall survival after surgery ( P<0.05). Age >32 years (HR=0.60, 95%CI: 0.41-0.86, P=0.006) was also an independent protective factor for disease-free survival, whereas later N stage was an independent risk factor (HR=1.69, 95%CI: 1.08-2.64, P=0.021). Conclusion:Young patients with early-onset gastric cancer aged ≤32 years have worse tumor differentiation and prognosis.

Objective To investigate the therapeutic mechanism of Shen Wu Yizhi Capsule in the treatment of post-stroke cognitive impairment(PSCI)by using network pharmacology methods and clinical trial validation.Methods A prospective trial was carried out in 90 cases of patients with PSCI admitted to Taihe Traditional Chinese Medicine Hospital Affiliated to Anhui University of Chinese Medicine from August 2022 to February 2024.The patients were randomly divided into the control group and the trial group by random number table method,with 45 cases in each group.The control group was treated with conventional treatment for PSCI,and the trial group was treated with Shen Wu Yizhi Capsule orally on the basis of treatment for the control group.The treatment course for the two groups covered 28 days.The changes of Mini-Mental State Examination(MMSE)score,Montreal Cognitive Assessment(MoCA)score,and the serum levels of inflammatory factors such as tumor necrosis factor α(TNF-α)and interleukin 6(IL-6)in the patients of the two groups were observed before and after treatment.Moreover,the incidences of adverse events in the two groups were recorded,thus to evaluate the safety of the treatment regimens in the two groups.And then the network pharmacological research was performed.TCMSP and literature review were used to obtain the active ingredients of Shen Wu Yizhi Capsule,GeneCards and other databases were used to obtain the PSCI disease targets,and the common targets were inputted into the STRING database to construct the PPI network.Cytoscape 3.9.0 was used to construct the network diagram of Shen Wu Yizhi Capsule-PSCI-targets,DAVID was used to perform GO and KEGG pathway enrichment analysis,and then molecular docking was used to verify the binding activity.Results(1)The results of clinical trial showed that after 28 days of treatment,the MMSE and MoCA scores of patients in the two groups were increased compared with those before treatment(P<0.05),and the increase of the scores in the trial group was significantly superior to that in the control group(P<0.05).The serum levels of TNF-α and IL-6 were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.05).During the trial,both groups of patients did not show obvious adverse reactions,with high safety.(2)The network pharmacological research of Shen Wu Yizhi Capsule yielded 92 active ingredients,803 targets,5 209 disease targets and 556 intersection targets.The core targets were AKT1,TNF,IL-6,TP53 and IL-1B,and the key compounds were deoxyharringtonine,senkyunone and genkwanin.The GO enrichment analysis obtained 1 812 GO entries,of which 154 entries were related with cellular component(CC),1 332 entries were related with biological process(BP),and 326 entries were related with molecular function(MF).The KEGG pathway enrichment analysis yielded 195 signaling pathways.The molecular docking results showed that the key compounds of Shen Wu Yizhi Capsule had good binding activities with the core targets.Conclusion The clinical efficacy of Shen Wu Yizhi Capsule in the treatment of PSCI is remarkable,and its therapeutic mechanism is probably related with multiple components through the signaling pathways such as AKT1,TNF,and IL-6.The results will provide reference for the in-depth study of Shen Wu Yizhi Capsule.

A 70-year-old female patient presented with fatigue and edema for 3 months and was found to have elevated serum creatinine for 3 weeks. During the course of the disease, she had fever and cough. Examinations revealed multiple ground-glass opacities in both lungs and positivity for myeloperoxidase-anti-neutrophil cytoplasmic antibodies (ANCA), leading to a diagnosis of ANCA-associated vasculitis. The patient′s condition initially improved after pulse glucocorticoid therapy combined with cyclophosphamide. During treatment, however, the patient developed hematochezia, and colonoscopy revealed multiple colonic ulcers. Immunohistochemistry of colonic mucosal biopsy confirmed cytomegalovirus (CMV) positivity, establishing a diagnosis of CMV colitis. The patient was found to have concurrent Clostridioidesdifficile and pulmonary infections. During the disease course, the patient also developed deep vein thrombosis and roxadustat-associated central hypothyroidism. Given the presence of multiple comorbidities, rituximab was subsequently used for vasculitis treatment, resulting in sustained remission. This case highlights the importance of highly individualized treatment strategies for older patients with vasculitis, requiring adjustment of immunosuppressive therapy intensity based on disease progression.

Periodontal bone defects, primarily caused by periodontitis, are highly prevalent in clinical settings and manifest as bone fenestration, dehiscence, or attachment loss, presenting a significant challenge to oral health. In regenerative medicine, harnessing developmental principles for tissue repair offers promising therapeutic potential. Of particular interest is the condensation of progenitor cells, an essential event in organogenesis that has inspired clinically effective cell aggregation approaches in dental regeneration. However, the precise cellular coordination mechanisms during condensation and regeneration remain elusive. Here, taking the tooth as a model organ, we employed single-cell RNA sequencing to dissect the cellular composition and heterogeneity of human dental follicle and dental papilla, revealing a distinct Platelet-derived growth factor receptor alpha (PDGFRA) mesenchymal stem/stromal cell (MSC) population with remarkable odontogenic potential. Interestingly, a reciprocal paracrine interaction between PDGFRA⁺ dental follicle stem cells (DFSCs) and CD31⁺ Endomucin⁺ endothelial cells (ECs) was mediated by Vascular endothelial growth factor A (VEGFA) and Platelet-derived growth factor subunit BB (PDGFBB). This crosstalk not only maintains the functionality of PDGFRA⁺ DFSCs but also drives specialized angiogenesis. In vivo periodontal bone regeneration experiments further reveal that communication between PDGFRA⁺ DFSC aggregates and recipient ECs is essential for effective angiogenic-osteogenic coupling and rapid tissue repair. Collectively, our results unravel the importance of MSC-EC crosstalk mediated by the VEGFA and PDGFBB-PDGFRA reciprocal signaling in orchestrating angiogenesis and osteogenesis. These findings not only establish a framework for deciphering and promoting periodontal bone regeneration in potential clinical applications but also offer insights for future therapeutic strategies in dental or broader regenerative medicine.
