ObjectiveTo investigate the inhibitory effects of curcumol （Cur） on the proliferation and metastasis of non-small cell lung cancer （NSCLC） cells and to explore the underlying mechanisms. MethodsIn vivo， a subcutaneous tumor xenograft model was established to evaluate the antiproliferative effect of Cur. In vitro， the cell counting kit-8 （CCK-8） assay was used to assess the effects of Cur at concentrations of 0， 60， 120， 240， 360， 480， 600， 720， 840， 960 μmol·L^-1 on the viability of NCI-A549 and NCI-H23 cells， and to evaluate its inhibitory effect on the proliferation of human bronchial epithelial BEAS-2B cells. Wound healing and Transwell migration assays were conducted to assess changes in cell migratory capacity following Cur treatment. Immunohistochemistry （IHC-P） was used to investigate the regulatory effect of Cur on the Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathway in tumor tissues. Western blot was performed to determine the protein expression levels of phosphorylated JAK2 （p-JAK2）， phosphorylated STAT3 （p-STAT3）， proliferating cell nuclear antigen （PCNA）， matrix metalloproteinase-2 （MMP-2）， matrix metalloproteinase-9 （MMP-9）， and vascular endothelial growth factor A （VEGFA） in tumor tissues and cells. To further verify the role of the JAK2/STAT3 signaling pathway in the pharmacological effects of Cur， rescue experiments were performed using the pathway agonist colivelin. ResultsIn vivo experiments showed that， compared with the model group， the tumor volumes of subcutaneous xenografts in nude mice in both low- and high-dose Cur groups were significantly reduced （P<0.05）， and the tumor inhibition rates were significantly increased （P<0.05）. The inhibitory effect in the high-dose group was comparable to that of the cisplatin group， and the body weight of mice in the Cur groups remained stable throughout the experiment. In vitro， compared with the control group， Cur at concentrations of 120 and 240 μmol·L^-1 inhibited the proliferation of NCI-A549 and NCI-H23 cells in a concentration-dependent manner （P<0.05）， with a significant inhibitory effect observed at 360 μmol·L^-1 （P<0.01）， while no significant effect on the viability of BEAS-2B cells was observed. Migration assays demonstrated that， compared with the control group， Cur treatment significantly reduced the migration rates of both cell lines in a concentration-dependent manner （P<0.05）， with an inhibitory effect at 360 μmol·L^-1 comparable to that of the cisplatin group. Mechanistic validation showed that， compared with the control group， the protein expression levels of p-JAK2 and p-STAT3 in tumor tissues and cells were significantly downregulated in the Cur groups （P<0.01）， and the expression levels of downstream proteins PCNA， MMP-2， MMP-9， and VEGFA were also significantly decreased with increasing Cur concentration （P<0.05）. In the rescue experiments， compared with the control group， colivelin pretreatment increased cell proliferation and migration rates （P<0.05） and upregulated the expression of related proteins （P<0.05）. Compared with the Cur group， the colivelin+Cur group showed significantly increased proliferation and migration rates （P<0.05）， along with significantly upregulated protein expression levels （P<0.05）. ConclusionCur can significantly inhibit the proliferation and metastasis of NSCLC both in vivo and in vitro， and its mechanism of action is closely associated with the inhibition of JAK2/STAT3 signaling pathway activation.

ObjectiveTo investigate the mechanisms by which oxyresveratrol （OXY） inhibits epithelial-mesenchymal transition （EMT） in non-small cell lung cancer （NSCLC） through the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway. MethodsCell counting kit-8 （CCK-8） assays were used to determine the survival rates of A549 and H1299 cells treated with different concentrations of OXY， and appropriate concentrations （0， 30， 60， 90 μmol·L^-1） were selected. The effects of OXY on the proliferation of A549 and H1299 cells were evaluated using 5-ethynyl-2′-deoxyuridine （EdU） assays and colony formation assays. Wound healing assays and Transwell invasion assays were performed to assess the effects of OXY on cell migration and invasion. Western blot （WB） was used to detect the expression levels of Snail， E-cadherin， N-cadherin， and Vimentin in A549 and H1299 cells. Network pharmacology and molecular docking were applied to predict the mechanism of action of OXY， and WB was used to evaluate the effects of OXY on proteins in the PI3K/Akt signaling pathway. Rescue experiments were conducted using the PI3K/Akt signaling pathway agonist 740Y-P. Under activation of the PI3K/Akt pathway， the effect of OXY on proliferation， migration， and invasion phenotypes， as well as on the expression levels of PI3K/Akt pathway-related proteins and EMT markers （Snail， E-cadherin， N-cadherin， and Vimentin）， were examined. ResultsIn the forward experiments， CCK-8 assay results showed that， compared with the control group， the survival rates of NSCLC cells in the OXY-treated groups （20-120 μmol·L^-1） were significantly decreased （P<0.05）. The half-maximal inhibitory concentration （IC₅₀） values of A549 and H1299 cells after 48 h of OXY treatment were 113.6 μmol·L^-1 and 92.53 μmol·L^-1， respectively. Therefore， concentrations of 0， 30， 60， 90 μmol·L^-1 were selected as the gradient for subsequent phenotypic and mechanistic studies. Compared with the control group， the proliferation rate， colony number， migration rate， and invasion number of NSCLC cells in the OXY groups （30， 60， and 90 μmol·L^-1） were significantly decreased （P<0.01， P<0.05）. WB results showed that， compared with the control group， the protein expression levels of Snail， N-cadherin， and Vimentin in NSCLC cells of the OXY groups were significantly decreased （P<0.05）， whereas E-cadherin expression was significantly increased （P<0.01）. Network pharmacology and molecular docking results indicated that OXY could act on the PI3K/Akt signaling pathway and exhibited good binding affinity with PI3K and Akt proteins. Further WB results showed that， compared with the control group， there were no statistically significant differences in the expression levels of PI3K and Akt proteins in NSCLC cells of the OXY groups， whereas the expression levels of phosphorylated PI3K （p-PI3K） and phosphorylated Akt （p-Akt） were significantly decreased （P<0.05）. In the rescue experiments， compared with the control group， the proliferation rate， colony number， migration rate， and invasion number of NSCLC cells in the 740Y-P group （15 μmol·L^-1） were significantly increased （P<0.01）. Compared with the control + OXY group （90 μmol·L^-1）， these indices in the 740Y-P + OXY group （15 μmol·L^-1 + 90 μmol·L^-1） were also significantly increased （P<0.01）. WB results showed that， compared with the control group， there were no statistically significant differences in the expression levels of PI3K and Akt proteins in the 740Y-P group. However， the expression levels of p-PI3K， p-Akt， Snail， N-cadherin， and Vimentin were significantly increased （P<0.05）， while E-cadherin expression was significantly decreased （P<0.01）. Compared with the control + OXY group， there were no statistically significant differences in PI3K and Akt protein expression in the 740Y-P + OXY group. However， the expression levels of p-PI3K， p-Akt， Snail， N-cadherin， and Vimentin were significantly increased （P<0.05）， while E-cadherin expression was significantly decreased （P<0.05）. ConclusionOXY inhibits the PI3K/Akt signaling pathway and suppresses the EMT process， thereby exerting anti-metastatic effects in NSCLC.

Lung cancer， particularly non-small cell lung cancer （NSCLC）， is the malignant tumor with the highest incidence and mortality in China and worldwide. In 2022， the global number of deaths reached 1.8 million， accounting for 18.7% of all cancer-related deaths， seriously threatening human health and life， and posing a severe challenge for prevention and treatment. Although treatment strategies for lung cancer have been continuously enriched in recent years， and progress has been made in targeted therapy and immunotherapy， long-term survival benefits remain limited due to primary or acquired drug resistance， low immune responsiveness， and chemotherapy-related toxicities. Therefore， there is an urgent need to explore safe and effective adjunctive therapeutic strategies. Traditional Chinese medicine （TCM）， with its advantages of holistic regulation and individualized syndrome differentiation， has played an increasingly prominent role in comprehensive cancer treatment. TCM holds that "Yang deficiency leads to accumulation" is a key pathogenesis of tumors. Based on the theory that "Yang transforms Qi， while Yin forms substance"， deficiency of Yang Qi results in impaired warming and transformation functions， leading to internal accumulation of Yin-cold. This is closely related to dysregulation of the immune microenvironment， "cold tumor" characteristics， and dysfunction of the neuroendocrine system in modern medicine. Accordingly， the therapeutic strategy of "warming Yang， supporting healthy Qi， and combating cancer" has gained increasing attention. In recent years， commonly used Yang-warming Chinese herbs， including Aconiti Lateralis Radix Praeparata， Zingiberis Rhizoma， Cinnamomi Cortex， Epimedii Folium， and Psoraleae Fructus， as well as their active constituents， have achieved notable progress in anti-lung cancer research by regulating multiple signaling pathways， inducing apoptosis， inhibiting metastasis， and reversing drug resistance. In addition， Yang-warming formulae such as Sini Tang and Yanghe Tang have shown promising effects in alleviating myelosuppression， improving cancer-related fatigue， managing malignant pleural effusion， and relieving cancer pain. These therapies exhibit toxicity-reducing and efficacy-enhancing effects， significantly improving patients' quality of life and survival benefits. To systematically summarize the roles and mechanisms of Yang-warming Chinese herbal medicines and compound formulae in lung cancer， this paper provides a comprehensive review of recent advances， aiming to offer insights for the clinical practice of TCM in the prevention and treatment of lung cancer.

Objective: To investigate the longitudinal association between biological rhythm trajectories and the risk of anxiety, depression, and comorbid symptoms among college students, so as to provide a cumulative empirical basis for early psychiatric tracking and mental health warning systems. Methods: Using random cluster sampling method, a baseline survey was conducted from April to May 2019. One comprehensive university and one medical university were selected in Shangrao City, Jiangxi Province, and Hefei City, Anhui Province, respectively. A total of 1 029 first year college students were recruited as study participants, and four waves of longitudinal follow up were carried out over a period of two years. The Self rating of Biological Rhythm Disorder for Adolescents was used to assess college students biological rhythms, and using the dynamic data from the first two follow ups to construct the trajectory of biological rhythm changes. Mental health outcomes (anxiety and depressive symptoms) at the end of the follow up period were assessed using Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9. Multivariable Logistic regression models were employed to evaluate the independent predictive value of distinct lifestyle rhythm trajectories on the detection risk of long term anxiety, depression, and their comorbid symptoms. Results: The prevalence rates of anxiety, depression, and comorbid symptoms among participants were 23.5%, 22.6%, and 16.7%, respectively. Multivariable Logistic regression analysis showed that, after adjusting for confounding factors such as sex, major, smoking, and alcohol consumption, compared with the persistent low risk reference group of overall biological rhythm, the persistent high risk trajectory group of overall assessment had an increased risk of anxiety symptoms( OR=3.87, 95%CI =2.45-6.11), depressive symptoms( OR=3.18, 95%CI =1.98-5.10), and comorbid symptoms( OR=2.43, 95%CI =1.46-4.04)(all P ＜0.05).Among college students in the elevated overall assessment risk group, the risks of anxiety symptoms ( OR=1.97, 95%CI =1.22-3.17), depressive symptoms ( OR=2.13, 95%CI =1.33-3.42), and comorbid symptoms ( OR=1.81, 95%CI =1.07-3.06) were also increased (all P < 0. 05), and the various risks in the group with increased risks were also higher than those in the group with consistently low risks. Conclusions The dynamic deterioration and persistent disruption of college students lifestyle and behavioral rhythms serve as strong early warning indicators for long term anxiety and depressive symptoms. Mental health screening in colleges and universities should incorporate multi timepoint dynamic tracking of behavioral rhythms, and circadian rhythm regulation should be regarded as a core target for group level mental health interventions.

Objective: To investigate the prevalence of human T-lymphotropic virus (HTLV) infection among blood donors in Hunan Province from 2022 to 2024. Methods: A total of 1 830 342 blood donors from 14 prefecture-level blood centers in Hunan Province over the past three years were screened for anti-HTLV-Ⅰ/Ⅱ using enzyme-linked immunosorbent assay (ELISA). Initially reactive samples were further tested with Line Immunoassay (LIA )/MP-Western blot and RT-PCR nucleic acid test for confirmation. Blood donors confirmed positive for HTLV were tracked and followed up. Results: From 2022 to 2024, the initial ELISA reactive rate for anti-HTLV-I/II among blood donors in Hunan Province was 1.36 per 10 000 (249/1 830 342). The confirmed positive rate was 0.20 per 10 000 (37/1 830 342), accounting for 14.86% of the initially reactive donors. The follow-up success rate for confirmed HTLV-positive blood donors was only 18.92%, while that for HTLV-indeterminate donors was 54.17%. Conclusion: The confirmed HTLV infection rates in Yueyang, Loudi, Shaoyang, Yiyang, and Zhuzhou cities were higher than the provincial (0.20 per 10 000). Chenzhou, Yongzhou, Zhangjiajie, and Xiangxi were identified as low prevalence areas, with an infection rate of 0. The overall follow-up success rate was low, indicating significant difficulties and bottlenecks in follow-up work. The comprehensive screening for HTLV and follow-up studies in Hunan provide valuable data to further improve blood safety testing strategies and risk warning mechanisms.

OBJECTIVE To investigate the effects of calcitriol on sepsis-induced immunosuppression and its potential mechanism. METHODS A sepsis-induced immunosuppression mice model was established using cecal ligation and puncture （CLP）. The 7-day survival rate， serum levels of tumor necrosis factor- α （TNF- α）， interleukin-6 （IL-6）， and IL-1β were determined in sham operation group， CLP group and calcitriol group （1 μg/kg）； the morphological changes of lung tissue in mice were observed. Lipopolysaccharide （LPS） tolerance macrophage models （representing sepsis-induced immunosuppression） were established using mice macrophage cell line RAW264.7 cells. The levels of TNF-α and IL-6 in cell supernatants as well as mRNA expressions of IL-1β， nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3）， IL-18 and caspase-1 were assessed in culture medium group， LPS group， LPS tolerance group， and calcitriol （5 μmol/L） group. The following parameters were measured： propidium iodide （PI）-positive cell ratio， caspase-1 activity， lactate dehydrogenase （LDH） release， and Ca2+ levels. RESULTS Compared with CLP group， 7-day survival rate and serum levels of TNF-α， IL-6 and IL-1β were increased significantly in calcitriol group （P＜0.05）. Additionally， pulmonary tissue damage was markedly attenuated in calcitriol group. Compared with LPS tolerance group， the levels of TNF-α and IL-6 in cell supernatants， mRNA expressions of IL- 1β， NLRP3， IL-18 and caspase-1， PI-positive cell ratio， caspase-1 activity， LDH release， and Ca2+ levels were all increased significantly in calcitriol group （P＜0.05）. CONCLUSIONS Calcitriol can reverse sepsis-induced immunosuppression， and the mechanism of action may be E-mail：yarfwy@163.com achieved by the binding of calcitriol to vitamin D receptor，which promotes the release of Ca2+ from the endoplasmic reticulum， thereby driving the NLRP3/caspase-1-mediated pyroptosis pathway.

OBJECTIVE: We aimed to investigate the patterns of fasting blood glucose (FBG) trajectories and analyze the relationship between various occupational hazard factors and FBG trajectories in male steelworkers. METHODS: The study cohort included 3,728 workers who met the selection criteria for the Tanggang Occupational Cohort (TGOC) between 2017 and 2022. A group-based trajectory model was used to identify the FBG trajectories. Environmental risk scores (ERS) were constructed using regression coefficients from the occupational hazard model as weights. Univariate and multivariate logistic regression analyses were performed to explore the effects of occupational hazard factors using the ERS on FBG trajectories. RESULTS: FBG trajectories were categorized into three groups. An association was observed between high temperature, noise exposure, and FBG trajectory ( P < 0.05). Using the first quartile group of ERS1 as a reference, the fourth quartile group of ERS1 had an increased risk of medium and high FBG by 1.90 and 2.21 times, respectively (odds ratio [ OR] = 1.90, 95% confidence interval [ CI]: 1.17-3.10; OR = 2.21, 95% CI: 1.09-4.45). CONCLUSION An association was observed between occupational hazards based on ERS and FBG trajectories. The risk of FBG trajectory levels increase with an increase in ERS.
