OBJECTIVES: Depressive and anxiety disorders are among the most common mental disorders worldwide and are associated with unhealthy lifestyle behaviors. The Life's Simple 7 (LS7) guideline proposed by the American Heart Association aims to reduce cardiovascular risk by improving behaviors such as diet and physical activity, but its impact on mental health is not yet fully clear. This study examined the association between LS7 scores and symptoms of anxiety and depression in adults undergoing routine health examinations. METHODS: Data were collected from individuals who underwent health examinations from May 2015 to December 2024 at the Health Management Center of the Third Xiangya Hospital. All participants completed the LS7 assessments, the Self-Rating Depression Scale (SDS), and the Self-Rating Anxiety Scale (SAS). Participants were categorized into 4 LS7 score groups: Low (≤7), average (8-9), good (10), and excellent (11-14). Those with SDS or SAS≥50 were classified as having mental disorder symptoms; with this group, SAS≥50 indicated anxiety, SDS≥50 indicated depression, and SDS and SAS≥50 indicated comorbid anxiety-depression. Binary logistic regression was used to assess associations between LS7 score and mental symptoms, calculating odds ratio (OR) and 95% confidence interval (CI). A restricted cubic spline (RCS) regression model was used to analyze the dose-response relationship between LS7 score (continuous variable) and the risk of mental symptoms. Nodes were set at the 5th, 35th, 65th, and 95th percentiles of the LS7 score, with the 5th percentile as the reference point. All models were adjusted for covariates such as gender, age, living alone, drinking status, education level, and sleep quality. Logistic regression framework was used to fit and calculate the adjusted OR (aOR) and 95% CI. Nonlinear relationship tests were also conducted. Subgroup analysis was performed to explore the interaction between gender, age, drinking habits, education level, and other factors and the LS7 score in influencing the risk of mental symptoms. RESULTS: A total of 5 449 participants were included; 1 363 (25.01%) had depressive symptoms, 398 (7.30%) had anxiety symptoms, and 259 (4.75%) had comorbid anxiety-depression. The prevalence of mental symptoms decreased significantly as LS7 scores increased. Univariate and multivariate Logistic regression indicated that LS7 score≥8 was protective against mental symptoms. Multivariate Logistic regression demonstrated moderate discriminative ability (AUC=0.672). Among individuals with anxiety, depression, or comorbid symptoms, LS7 score distributions showed a graded decrease from poor to excellent groups. After adjustment, an excellent LS7 score was associated with a 39% lower risk of depression (aOR=0.61, 95% CI 0.47 to 0.78, P<0.001), a 63% lower risk of anxiety (aOR=0.37, 95% CI 0.22 to 0.59, P<0.001), and a 66% lower risk of comorbid anxiety-depression (aOR=0.34, 95% CI 0.17 to 0.62, P=0.001). The AUC values of the anxiety model, depression model, and comorbid anxiety and depression model were 0.632, 0.672, and 0.619, respectively. All models demonstrated moderate discriminatory ability, which was statistically significant, but their capacity to distinguish cases from non-cases was limited. RCS analysis confirmed a linear inverse relationship between LS7 score and mental symptom risk. Not smoking and regular physical activity were the strongest protective behaviors. Subgroup analysis suggested stronger protective effects in men, younger adults (≤60), non-drinkers, and those with higher education levels, and revealed a significant interaction between alcohol use and LS7 score (P for interaction=0.021), indicating that alcohol consumption may weaken the protective effect of LS7. CONCLUSIONS Ideal healthy lifestyle behaviors, as reflected by higher LS7 scores, are associated with lower risks of anxiety and depression in adults. Promoting LS7-based lifestyle practices may serve as a practical and effective strategy for the prevention and management of anxiety and depression in both clinical and daily life settings.

Humans and animals have a fundamental ability to use experiences and environmental information to organize behavior. It often happens that humans and animals make decisions and prepare actions under uncertain situations. Uncertainty would significantly affect the state of animals' minds, but may not be reflected in behavior. How to "read animals' mind state" under different situations is a challenge. Here, we report that neuronal activity in the medial prefrontal cortex (mPFC) of rats can reflect the environmental uncertainty when the task situation changes from certain to uncertain. Rats were trained to perform behavioral tasks under certain and uncertain situations. Under certain situations, rats were required to simply repeat two nose-poking actions that each triggered short auditory tone feedback (single-task situation). Whereas under the uncertain situation, the feedback could randomly be either the previous tone or a short musical rhythm. No additional action was required upon the music feedback, and the same secondary nose-poking action was required upon the tone feedback (dual-task situation); therefore, the coming task was uncertain before action initiation. We recorded single-unit activity from the mPFC when the rats were performing the tasks. We found that in the dual task, when uncertainty was introduced, many mPFC neurons were actively engaged in dealing with the uncertainty before the task initiation, suggesting that the rats could be aware of the task situation change and encode the information in the mPFC before the action of task initiation.

As the field of oral pathology has evolved, the nomenclature and classification of oral mucosal diseases with a remarkable risk of malignant transformation have undergone several modifications. In 2005, the World Health Organization (WHO) introduced the concept of oral potentially malignant disorders (OPMDs) as an alternative to the terms for oral precancerous lesions and precancerous conditions. In the consensus report by the WHO Collaborating Center for Oral Cancer of 2021, OPMD is defined as "any oral mucosal abnormality that is associated with a statistically increased risk of developing oral cancer."This definition encompasses a range of conditions, in-cluding oral leukoplakia, oral submucous fibrosis, proliferative verrucous leukoplakia, oral lichen planus, and other lesions. In light of the complex etiology, unclear pathogenesis, and carcinogenesis of OPMDs, early and precise diagnosis and treatment can contribute to the secondary prevention of oral cancer. For this reason, this review, which aims to provide a basis for the precise clinical diagnosis of OPMDs, was performed. Its aim was achieved by reviewing the historical evolution and research progress of the nomenclature, classification, and histopathological diagnostic criteria of OPMDs.

Objective: To investigate the incidence and risk factors of catheter-related venous thrombosis (PICC-DVT) after peripherally inserted central catheter (PICC) in patients with hematologic malignancies, and to analyze the safety of anti-coagulation therapy with low-molecular-weight heparin. Methods: From August 2016 to June 2018, 43 patients with hematologic malignancies received PICC in Baoan District People's Hospital of Shenzhen City were enrolled. The patients were divided into low-molecular-weight heparin anticoagulation group (22 cases) and blank control group (21 cases) according to the random number table method. The blood routine, coagulation quadruple, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity before and after catheterization were compared between the two groups. Results: Of the 43 patients, 5 cases (11.62%) occurred PICC-DVT within 1 month after PICC, including 2 cases (9.09%) in the low-molecular-weight heparin anticoagulation group, and 3 cases (14.29%) in the blank control group, the difference between the two groups was not statistically significant (P = 0.664). No pulmonary embolism occurred in all patients with PICC-DVT. One case in the blank control group developed PICC-DVT and catheter-associated staphylococcus aureus infection, the patient was extubated after anti-infection and thrombolytic therapy, the other patients with PICC-DVT were not extubated, and the thrombus was dissolved after anticoagulant therapy. There were no significant differences in the white blood cell count, platelet count, prothrombin time, activated partial thromboplastin time, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity between the low-molecular-weight heparin anticoagulation group and blank control group (all P > 0.05). The anticoagulant index (protein C, protein S or antithrombin Ⅲ activity) was decreased in 5 patients with PICC-DVT, and in 38 non-thrombotic patients, the anticoagulant index was reduced in 16 patients (42.11%), the difference was statistically significant (P = 0.021). Conclusions The incidence of protein C, protein S or antithrombin Ⅲ activity reduction in hematological malignancies patients with PICC-DVT is higher than that in non-thrombotic patients. Low-molecular-weight heparin anticoagulant therapy can not reduce the occurrence of PICC-DVT within 1 month after PICC in patients with hematological malignancies, but the treatment is safe and has no relevant bleeding event.

Objective:This work aims to use the characteristics of dendritic cells (DCs) pulsed with recombinant human HSP70, which can present and process tumor antigens, to enhance the killing activity of cytotoxic t lymphocytes (CTLs) against breast neoplasms. Methods:Autologous DCs were isolated from peripheral blood mononuclear cells and then stimulated in vitro with granulocyte macrophage-colony stimulating factor and interleukin-4. The DCs were loaded with A549 tumor cell freeze-thaw lysate, and rhHSP70 was added as an immune adjuvant. The specific groups were subjected to tumor-specific cytotoxic assay, enzyme-linked immunosorbent assay, and fluores-cence-activated cell sorting. Results:DCs pulsed with A549 tumor cell lysate enhanced the growth expansion of CTLs, upregulated CD40 and CD80 populations in CTLs, and augmented Th1 cytokines. In addition, the cytotoxicity of specific CTLs against A549 was highly enhanced. The above indications became more obvious after the addition of rhHSP70. Conclusion:DCs pulsed with freeze-thaw cell lysates derived from breast cancer can enhance growth expansion of lymphocytes. They may serve as an effective tumor antigen to stimulate the proliferation of specific CTLs, which are very effective in activating specific T-cell responses against breast cancer cells in vitro. The improved anti-tumor immunity response by DC-based vaccines may be related to the maturation of the DCs promoted by rhHSP70.
