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 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.

Objective To investigate the impact of two different surgical methods, orthotopic kidney transplantation and abdominal heterotopic kidney transplantation, on the surgical outcomes of pig-to-pig kidney transplantation and the short-term survival of recipient pigs after surgery. Methods Twenty-four Bama miniature pigs were divided into two groups, with 12 pigs in each group, and underwent orthotopic kidney transplantation and abdominal heterotopic kidney transplantation, respectively. The perioperative indicators of the recipient pigs, renal blood perfusion, the overall incidence rate of complications and survival rate were compared between the two surgical methods. Results The total surgical time, renal artery anastomosis time, renal vein anastomosis time, cold ischemia time and total ischemia time were all shorter in the abdominal heterotopic kidney transplantation group than in the orthotopic kidney transplantation group, with statistically significant differences (all P<0.05). The number of satisfactory renal perfusion cases was higher in the abdominal heterotopic kidney transplantation group than in the orthotopic kidney transplantation group (83% vs. 75%), but the difference was not statistically significant (P>0.05). The total incidence of postoperative complications was 33% in the heterotopic kidney transplantation group, with a survival rate of 92%, and the cause of death was rupture of the vascular anastomosis. The total incidence of postoperative complications was 50% in the orthotopic kidney transplantation group, with a survival rate of 83%, and the causes of death were renal vein thrombosis and renal artery thrombosis. There were no statistically significant differences in the total incidence of postoperative complications and survival rates between the two groups (all P>0.05). Conclusions Compared with orthotopic kidney transplantation, abdominal heterotopic kidney transplantation showes better surgical outcomes in pig-to-pig kidney transplantation and is more beneficial for the short-term survival of recipient pigs after surgery. This provides experience for improving the stability of pig-to-non-human primate kidney xenotransplantation models in the future.

BACKGROUND:
The primary limitation to kidney transplantation is organ shortage. Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation.
METHODS:
We conducted a kidney xenotransplantation in a brain-dead human recipient using a porcine kidney with five gene edits (5GE) on March 25, 2024 at Xijing Hospital, China. Clinical-grade immunosuppressive regimens were employed, and the observation period lasted 22 days. We collected and analyzed the xenograft function, ultrasound findings, sequential protocol biopsies, and immune surveillance of the recipient during the observation.
RESULTS:
The combination of 5GE in the porcine kidney and clinical-grade immunosuppressive regimens prevented hyperacute rejection. The xenograft kidney underwent delayed graft function in the first week, but urine output increased later and the single xenograft kidney maintained electrolyte and pH homeostasis from postoperative day (POD) 12 to 19. We observed AMR at 24 h post-transplantation, due to the presence of pre-existing anti-porcine antibodies and cytotoxicity before transplantation; this AMR persisted throughout the observation period. Plasma exchange and intravenous immunoglobulin treatment mitigated the AMR. We observed activation of latent porcine cytomegalovirus toward the end of the study, which might have contributed to coagulation disorder in the recipient.
CONCLUSIONS
5GE and clinical-grade immunosuppressive regimens were sufficient to prevent hyperacute rejection during pig-to-human kidney xenotransplantation. Pre-existing anti-porcine antibodies predisposed the xenograft to AMR. Plasma exchange and intravenous immunoglobulin were safe and effective in the treatment of AMR after kidney xenotransplantation.

BACKGROUND:
Immune checkpoint inhibitors (ICIs) have been included in various neoadjuvant therapy (NAT) regimens for non-small cell lung cancer (NSCLC). However, due to the relatively short period for the use of ICIs in NAT, patients' clinical outcomes with different regimens are uncertain. Our study aims to examine the efficacy of neoadjuvant immunotherapy (NAIT) for NSCLC patients and compare the overall survival (OS) and event-free survival (EFS) of patients receiving different NAT regimens.
METHODS:
This study retrospectively included 308 NSCLC patients treated with different NAT regimens and subsequent surgery in National Cancer Center between August 1, 2016 and July 31, 2022. Kaplan-Meier survival analysis and Cox proportional hazards regression analysis were conducted to evaluate the prognosis of patients.
RESULTS:
With a median follow-up of 27.5 months, the 1-year OS rates were 98.8% and 96.2%, and the 2-year OS rates were 96.6% and 85.8% in patients of the NAIT and neoadjuvant chemotherapy (NACT) group, respectively (hazard ratio [HR], 0.339; 95% confidence interval [CI], 0.160-0.720; P = 0.003). The 1-year EFS rates were 96.0% and 88.0%, and the 2-year EFS rates were 92.0% and 77.7% for patients in the NAIT and NACT groups, respectively (HR, 0.438; 95% CI, 0.276-0.846; P = 0.010). For patients who did not achieve pathological complete response (pCR), significantly longer OS ( P = 0.012) and EFS ( P = 0.019) were observed in patients receiving NAIT than those receiving NACT. Different NAT regimens had little effect on surgery and the postoperative length of stay (6 [4, 7] days vs . 6 [4, 7] days, Z = -0.227, P = 0.820).
CONCLUSIONS
NAIT exhibited superior efficacy to NACT for NSCLC, resulting in longer OS and EFS. The OS and EFS benefits were also observed among patients in the NAIT group who did not achieve pCR.

Metabolic diseases have seen a steady increase in incidence in recent years, becoming one of the main causes of sub-health status globally. Neutrophil extracellular traps(NETs) are reticular complexes containing DNA, which trap foreign microorganisms or induce an immune response. Current research indicates that NETs are widely active in various metabolic diseases and can cause severe damage to the body through multiple mechanisms, including promoting blood glucose elevation, damaging vascular endothelial cells, forming vascular embolisms, triggering intense inflammation, and promoting lipid accumulation. Therefore, intervening in NETs is an important approach to treating metabolic diseases. Research has shown a close relationship between the theory of spleen heat-turbid toxin theory and metabolic diseases-NETs mechanism. The basic pathogenesis include the internal accumulation of phlegm-dampness, qi stagnation and blood stasis, internal accumulation of dampness-heat, phlegm and blood stasis, and flourishing toxic heat. Various Chinese herbal medicines with the functions of dispelling dampness, resolving phlegm, promoting blood circulation to remove blood stasis, and clearing heat and toxins, along with their extracts and compound prescriptions, can treat metabolic diseases by regulating NETs and delaying disease progression. This paper systematically outlined the formation mechanisms of NETs, their connection to metabolic diseases, the theoretical basis in TCM, their roles in numerous metabolic diseases, and the current research status of TCM in regulating NETs to prevent and control metabolic diseases, aiming to provide effective reference ideas for developing therapeutic strategies for metabolic diseases.
