The Expert Consensus on the Deployment of DeepSeek in Medical Institutions serves as a detailed guideline for the deployment of DeepSeek in medical institutions. It was developed by experts in the fields of healthcare， hospital management， medical information， health policy， law， and medical ethics from nearly 30 leading domestic medical and academic research institutions， based on relevant domestic and international laws and regulations as well as the practices of medical institutions. It aims to provide medical institutions with a scientific， standardized， and secure deployment guideline to ensure that the application of artificial intelligence （AI） technologies in healthcare， including but not limited to DeepSeek， conforms to the unique characteristics of the healthcare industry and effectively promotes the improvement of medical service levels. From the three aspects of pre-deployment evaluation， deployment implementation， and post-deployment management and monitoring， the key factors that medical institutions should consider when introducing DeepSeek were elaborated in detail， including medical demand compatibility， technical capabilities and infrastructure， legal and ethical risks， data preparation and management， model selection and optimization， system integration and training， performance monitoring and continuous optimization， risk management and emergency response， as well as compliance review and evaluation. This provides a comprehensive deployment framework for medical institutions to ensure the safety and effectiveness of technology applications.

This review described the potential health threats to the cardiovascular system from micro-nano plastics (MNPs) and their multifaceted toxicity mechanisms. The article reviewed the environmental distribution of MNPs, exposure pathways, and their toxic effects on the cardiovascular system, and summarized the specific mechanisms of MNPs involving oxidative stress, inflammatory response, mitochondrial damage, apoptosis, pyroptosis, and autophagy dysregulation. Meanwhile, the combined toxic effects of MNPs with other environmental pollutants (e.g., heavy metals and polycyclic aromatic hydrocarbons), including synergistic, antagonistic, and dual effects, were analyzed, and the potential risks of MNPs as carriers of microorganisms and toxic chemicals were pointed out. The widespread presence of MNPs and their complex toxicity mechanisms may make them important triggers for cardiovascular diseases, but current research still suffers from unbalanced studies across environmental systems, incomplete understanding of plastic properties, and limited knowledge of long-term biological effects. Future research should focus on the long-term effects of MNPs, the joint toxicity mechanisms with other pollutants, and the differential effects across population subgroups. It is suggested to accelerate plastic recycling technology innovation, promote biodegradable materials, and optimize waste treatment process to mitigate the potential threat of MNPs pollution to human health. Through multidisciplinary collaboration and in-depth research, combining innovative concepts from toxicology, public health policy, and environmental science, it is expected to provide new methods and approaches for the prevention and treatment of cardiovascular diseases associated with MNPs.

Objective:To investigate the role of iron death in paraquat (PQ) -induced alveolar epithelial mesangialization (EMT) .Methods:In August 2023, the appropriate PQ staining concentration as well as the intervention concentration of lipoinhibitor-1 (Lip-1) were screened by CCK8 method. The RLE-6TN cells were divided into three groups, which were control group, PQ group and iron death inhibition group, 200 μmol/L PQ solution was given to the PQ group, and PQ 200 μmol/L and 0.1 μmol/L Lip-1 solution was given to the iron death inhibition group, the control group was added the same amount of cell medium. morphological changes and migratory viability of the cells in each group were observed at 12 h, 24 h and 48 h after the poisoning, and the contents of ferrous ions (Fe 2+), reactive oxygen radicals (ROS), glutathione (GSH), superoxide dismutase (SOD), and malondialdehyde (MDA) were detected in each group; meanwhile, qRT-PCR and western-blot were used to determine the molecular expression of E-cadherin, α-smooth muscle actin (α-SMA), and Collagen I in the cells in each group. The difference between group was compared by ANOVA, and the further pairwise comparison was conducted by Bonferroni method. Results:Cell viability was detected using CCK8, and the results showed that the cell survival rate of RLE-6TN cells treated with 200 μmol/L PQ+0.1 μmol/L Lip-1 solution was 56.6%. The migration activity of RLE-6TN cells in the iron death inhibition group was weaker than that in the PQ group after 24 and 48 hours of exposure, and the degree of EMT changes in the cells was reduced compared to the PQ group. After 12, 24, and 48 hours of exposure, the Fe 2+ concentration, ROS fluorescence intensity, and MDA content in the iron death inhibition group decreased compared to the corresponding time points in the PQ group ( P<0.05/3), while compared with PQ group, the GSH concentration and SOD concentration increased compared to the corresponding time points in the PQ group ( P<0.05/3). The results showed that compared with the control group, the expression levels of E-cadherin mRNA and protein in PQ group and iron death inhibition group were both decreased ( P<0.05/3), while compared with PQ group, the expression levels of E-cadherin mRNA and protein in iron death inhibition group were increased ( P<0.05/3) ; Compared with the control group, the expression levels of α-SMA, Collagen I mRNA and protein in PQ group and iron death inhibition group cells increased ( P<0.05/3), while compared with PQ group, the expression levels of α-SMA, Collagen I mRNA and protein in iron death inhibition group cells decreased ( P<0.05/3) . Conclusion:Ferroptosis is involved in the EMT process of alveolar epithelial cells induced by PQ. Inhibiting ferroptosis can reduce cellular oxidative damage and alleviate the degree of cellular EMT.

Objective:To investigate the role of connective tissue growth factor (CTGF) and PI3K/Akt signaling pathways in paraquat (PQ) -induced alterations in alveolar epithelial cell mesenchymalization (EMT) .Methods:In February 2023, RLE-6TN cells were divided into 2 groups, which were set as uncontaminated group and contaminated group (200 μmol/L PQ), and cellular EMT alteration, CTGF and PI3K/Akt signaling pathway related molecules expression were detected by cell scratch assay, qRT-PCR and western-blot assay. Using shRNA interference technology to specifically inhibit the expression of CTGF, RLE-6TN cells were divided into four groups: control group, PQ group (200 μmol/L PQ), interference group (transfected with a plasmid with shRNA-CTGF+200 μmol/L PQ), and null-loaded group (transfected with a plasmid with scramble- CTGF+200 μmol/L PQ), qRT-PCR and western blot were used to examine the alteration of the cellular EMT and the expression of molecules related to the activity of PI3K/Akt pathway. The PI3K/Akt signaling pathway was blocked by the PI3K inhibitor LY294002, and the expression of EMT-related molecules in cells of the control group, PQ group (200 μmol/L PQ), and inhibitor group (200 μmol/L PQ+20 μmol/L LY294002) was examined by qRT-PCR and western blot.The t-test was used to compare the differences between the two groups, while the analysis of variance (ANOVA) was applied to compare the differences among multiple groups. For further pairwise comparisons, the Bonferroni method was adopted.Results:The results of cell scratch test showed that compared with the uncontaminated group, RLE-6TN cells in the contaminated group had faster migration rate, lower mRNA and protein expression levels of E-Cadherin, and higher mRNA and protein expression levels of α-SMA, CTGF, PI3K and Akt, with statistical significance ( P<0.05). After specific inhibition of CTGF expression, the mRNA and protein expression of CTGF, PI3K, Akt, and α-SMA in the cells of the interference group were significantly lower than that of the PQ group and the null-loaded group ( P<0.05/6), whereas that of E-Cadherin was higher than that of the PQ group and the null-loaded group ( P<0.05/6). Specifically blocking the PI3K/Akt signaling pathway, the mRNA and protein expression of PI3K, Akt and α-SMA in the cells of the inhibitor group was decreased compared with that of the PQ group ( P<0.05/3), while the expression of E-Cadherin was elevated compared with that of the PQ group ( P<0.05/3) . Conclusion:CTGF may promote PQ-induced alveolar epithelial cell EMT through activation of the PI3K/Akt signaling pathway. Inhibition of CTGF expression or blockade of PI3K/Akt signaling pathway activity can alleviate the extent of PQ-induced alveolar epithelial cell EMT.
