With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Objective To investigate the effect of asperuloside(ASP)on the malignant progression and chemotherapy resistance of hepatocellular carcinoma(HCC)cells by regulating the supersonic hedgehog(SHH)/glioma-associated oncogene homolog 1(GLI1)signaling pathway.Methods The expression of SHH and GLI1 protein in human hepatocellular carcinoma cell line(SMMC-7721)/adriamycin(ADM)and SMMC-7721 cell line were detected by Western blot(WB).The HCC drug-resistant cell line SMMC-7721/ADM were divided into Control group,ADM group,L-ASP group(1 mmol/L ASP),M-ASP group(2 mmol/L ASP),H-ASP group(3 mmol/L ASP),ASP+PM group(1 μmol/L SHH/GLI1 signaling pathway activator PM).Ex-cept for Control group,5 μg/mL ADM was added to each group.The effect of ASP on the proliferation of SMMC-7721/ADM cells was detected by cell counting kit-8(CCK8)assay and plate cloning assay.The effect of ASP on the invasion and migration of SMMC-7721/ADM cells were detected by Transwell assay.The effect of ASP on the apoptosis of SMMC-7721/ADM cells was detected by flow cytometry.The expression of SHH,GLI1,proliferating cell nuclear antigen(PCNA),matrix metalloproteinase-9(MMP-9)and B cell lymphoma-2 associated X protein(Bax)in SMMC-7721/ADM cells were detected by WB.Animal experiments verified the effect of ASP on the growth of HCC xenografts and the expression of SHH/GLI1 signaling pathway proteins.Results The expression of SHH and GLI1 in SMMC-7721/ADM cells were higher than those in SMMC-7721 cells(P＜0.05).L-ASP group,M-ASP group and H-ASP group decreased the proliferation,migration and in-vasion of SMMC-7721/ADM cells in a dose-dependent manner,decreased the expression of SHH,GLI1,PCNA and MMP-9,and promoted cell apoptosis and Bax expression(P＜0.05).SHH/GLI1 signaling pathway acti-vator PM could reverse the inhibitory effect of H-ASP treatment on malignant progression and chemotherapy resistance of SMMC-7721/ADM cells(P＜0.05).ASP could inhibit the growth of HCC transplanted tumor and the expression of SHH and GLI1(P＜0.05).Conclusion ASP can inhibit the malignant progression of HCC cells and enhance the sensitivity of chemotherapy,which may be achieved by inhibiting the SHH/GLI1 signaling pathway.
