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.

ObjectiveTo investigate the mechanisms by which eupatilin (Eup) inhibits proliferation, invasion, and metastasis of non-small cell lung cancer (NSCLC) through the enhancer of zeste homolog 2/histone H3 lysine 27 trimethylation (EZH2/H3K27me3) signaling pathway. MethodsIn vivo, a subcutaneous xenograft tumor model was established in nude mice using H1299 cells to evaluate the anti-NSCLC effects of Eup. Immunohistochemistry (IHC-P) was used to detect the expression of proliferation- and invasion/metastasis-related proteins, including proliferating cell nuclear antigen (PCNA), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor A (VEGFA). In vitro, cell counting kit-8 (CCK-8) assays were performed to determine the viability of H1299 cells treated with different concentrations of Eup (0-200 μmol·L-1) and to select appropriate concentrations. Colony formation and 5-ethynyl-2′-deoxyuridine (EdU) assays were used to evaluate cell proliferation. Wound healing and invasion assays were conducted to assess cell migration and invasion. Human umbilical vein endothelial cell (HUVEC) angiogenesis assays were used to evaluate the effects of Eup on angiogenesis. Transcriptomic analysis was performed to identify the targets of Eup in H1299 cells and to explore its major functions. Molecular docking and molecular dynamics simulations were conducted to predict the binding affinity and interaction stability between Eup and its target proteins. Western blot was used to detect the effects of Eup on the expression levels of EZH2/H3K27me3 pathway-related proteins and proliferation- and invasion/metastasis-related proteins, including PCNA, MMP-2, MMP-9, and VEGFA. ResultsIn the subcutaneous xenograft model, compared with the model group, Eup treatment dose-dependently inhibited the growth of H1299 xenograft tumors, and the tumor inhibition rate was significantly increased (P<0.05). IHC-P results showed that, compared with the model group, high-dose Eup significantly reduced the expression levels of PCNA, MMP-2, MMP-9, and VEGFA in vivo (P<0.05). In vitro, compared with the control group, Eup inhibited the proliferation, invasion, and metastasis of NSCLC cells in a concentration-dependent manner. Transcriptomic analysis further showed that, compared with the control group, Eup significantly downregulated EZH2 expression, and its functional effects were associated with inhibition of tumor metastasis. Molecular docking and molecular dynamics simulations indicated that Eup exhibited strong binding affinity with EZH2 and stable interactions. Western blot results demonstrated that, compared with the model group, Eup significantly inhibited, in a dose-dependent manner, the expression levels of EZH2, H3K27me3, and proliferation- and invasion/metastasis-related proteins (PCNA, MMP-2, MMP-9, and VEGFA) in both in vivo and in vitro experiments (P<0.05). In vitro, compared with the control group, overexpression of EZH2 via plasmid transfection partially reversed the inhibitory effects of Eup on the expression of key proteins involved in proliferation and invasion/metastasis in H1299 cells. ConclusionEup effectively inhibits the proliferation, migration, and invasion of H1299 cells both in vivo and in vitro. The underlying mechanism may be related to inhibition of the EZH2/H3K27me3 signaling pathway and downregulation of proliferation- and invasion/metastasis-related proteins, including PCNA, MMP-2, MMP-9, and VEGFA. Eup may serve as a potential therapeutic agent for suppressing proliferation and invasion/metastasis 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.

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.

ObjectiveCell adhesion is a critical process that regulates cellular physiological functions. Quantitative characterization of adhesion dynamics is essential for elucidating the intrinsic mechanical mechanisms underlying cellular activities. Although atomic force microscopy-based single-cell force spectroscopy is widely used for single-cell adhesion measurements, it requires complex chemical modifications for preparation of live-cell probes, leading to limitations such as cumbersome operation, low throughput, and potential impacts on cell viability. Fluidic force microscopy, which combines atomic force microscopy with microfluidic probes, is a technique allowing the operation of force-controlled nanopipettes in aqueous environments. By applying negative or positive pressure via a pressure controller, a single living cell can be captured onto or released from the cantilever under physiological conditions. This procedure offers a simple workflow and high assay throughput for single-cell adhesion measurements without the need for chemical functionalization. In this study, fluidic force microscopy-based single-cell force spectroscopy was adopted to achieve long-term quantitative characterization of single-cell adhesion dynamics in a simpler and more efficient manner, comparing the dynamic differences in adhesion establishment between two cell lines with different differentiation levels. MethodsHEK 293T and hTERT RPE-1 cells were non-invasively captured on the cantilever of a fluidic force microscope via its integrated microfluidic system during 40 h of adhesion culture. Cell-substrate detachment assays were performed, and force-distance curves were recorded to extract key mechanical adhesion parameters, including adhesion force, adhesion energy, and maximum detachment distance. These measurements were combined with real-time monitoring of cell spreading area to systematically characterize the dynamic evolution of single-cell adhesion. ResultshTERT RPE-1 cells rapidly entered a stable adhesion phase within 1 h after seeding, with both area-normalized adhesion force and area-normalized adhesion energy reaching peak values. In contrast, HEK 293T cells required 4 h to achieve stable adhesion. Subsequently, the adhesion force, adhesion energy and maximum detachment distance of hTERT RPE-1 and HEK 293T cells stabilized at approximately 240 nN vs. 30 nN, 2.2 pJ vs. 0.12 pJ and 6 μm vs. 4 μm, respectively. hTERT RPE-1 cells reached the peak of area-normalized adhesion parameters earlier than HEK 293T cells, with their peak area-normalized adhesion force and area-normalized adhesion energy being substantially elevated relative to HEK 293T cells. HEK 293T cells presented stronger linear correlations among adhesion energy, maximum detachment distance and adhesion force compared with hTERT RPE-1 cells. For both cell lines, cell spreading area exhibited a weak correlation with adhesion force. Whereas the area-normalized adhesion parameters of HEK 293T cells remained relatively constant throughout the adhesion process, hTERT RPE-1 cells exhibited elevated values in the early phase, followed by a gradual decline. These results indicated distinct dynamic adhesion patterns between the two cell types, with hTERT RPE-1 cells exhibiting stronger adhesion strength and higher adhesion efficiency. ConclusionIn this study, fluidic force microscopy-based single-cell force spectroscopy was successfully applied to perform long-term in situ quantitative measurement of the adhesion dynamics in single adherent cells. The approach revealed divergent adhesion patterns between HEK 293T and hTERT RPE-1 cells, suggesting a close association between cell differentiation and adhesion behaviors. These findings provide quantitative mechanical evidence for further understanding the underlying mechanisms of cell adhesion.

Objective:
To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school.
Methods:
From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention.
Results:
After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05).
Conclusion
The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.
