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 effects of chronic starvation stress on the proliferation and migration of colorectal cancer cells, as well as the underlying mechanisms. Methods By using prolonged serum starvation to simulate chronic starvation stress in tumor cells, we established enduring serum-deprived models of SW480 and DLD-1 cells and observed cellular morphological change. Effects of prolonged serum starvation on SW480 and DLD-1 proliferative and migratory capabilities were assessed using CCK-8 and Transwell assays. Differential gene-expression analysis on SW480 cultured with 1% FBS or 10% FBS medium was followed by GO and KEGG pathway assessments. Migration-related protein interactions were explored using String database and Metascape software, leading to 16 genes being selected for RT-qPCR validation. Protein levels of ITGB1 and key molecules in the relevant pathways were measured. Mobility changes in SW480 were observed through Transwell assay after ITGB1 knockdown or STAT3 inhibition. Results Prolonged serum starvation significantly inhibited the proliferation of SW480 and DLD-1 cells, and DLD-1 mobility, while enhanced SW480 migration. Transcriptome analysis revealed that prolonged serum deprivation caused the upregulation of 3016 genes, among which 283 were involved in cell migration. Metascape analysis identified the correlations among potential core genes ITGB1, CD44, TNS1, STAT3, etc. Prolonged serum deprivation increased the mRNA levels of VTN, TNS1, VEGFA, STAT3, and ITGB1 while also increasing the protein levels of ITGB1 and MMP2 and the phosphorylation levels of JAK2 and STAT3. Mobility reduction in prolonged serum-starved SW480 cells was achieved through ITGB1 knockdown or a STAT3 inhibitor. Conclusion Colorectal cancer cells can endure chronic starvation stress which enhances migration capability by upregulating ITGB1 expression.

As a serious public health problem, alcohol use disorder has brought a huge burden of disease to patients, families, and society. At present, a growing number of studies have shown that brain function is impaired in patients with alcohol use disorder. During recent years, with continuous development in neuroimaging technology, resting-state functional magnetic resonance imaging technology has been applied in multiple studies for brain functions related to alcohol use disorder, which provides new cues for understanding the pathophysiology of the disorder. This article reviewed publications about resting-state functional magnetic resonance imaging applicated in alcohol use disorder in recent years, by such to provide some helps in theoretical bases for future studies along this line.

Nonpharmaceutical interventions (NPIs) have been commonly deployed to prevent and control the spread of the coronavirus disease 2019 (COVID-19), resulting in a worldwide decline in influenza prevalence. However, the influenza risk in China warrants cautious assessment. We conducted a cross-sectional, seroepidemiological study in Shandong Province, Northern China in mid-2021. Hemagglutination inhibition was performed to test antibodies against four influenza vaccine strains. A combination of descriptive and meta-analyses was adopted to compare the seroprevalence of influenza antibodies before and during the COVID-19 pandemic. The overall seroprevalence values against A/H1N1pdm09, A/H3N2, B/Victoria, and B/Yamagata were 17.8% (95% CI 16.2%-19.5%), 23.5% (95% CI 21.7%-25.4%), 7.6% (95% CI 6.6%-8.7%), and 15.0 (95% CI 13.5%-16.5%), respectively, in the study period. The overall vaccination rate was extremely low (2.6%). Our results revealed that antibody titers in vaccinated participants were significantly higher than those in unvaccinated individuals (P < 0.001). Notably, the meta-analysis showed that antibodies against A/H1N1pdm09 and A/H3N2 were significantly low in adults after the COVID-19 pandemic (P < 0.01). Increasing vaccination rates and maintaining NPIs are recommended to prevent an elevated influenza risk in China.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide. HCC is refractory to many standard cancer treatments and the prognosis is often poor, highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments. Kinesin family member 2C (KIF2C) is reported to be highly expressed in several human tumors. Nevertheless, the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated. In this study, we found that KIF2C expression was significantly upregulated in HCC, and that KIF2C up-regulation was associated with a poor prognosis. Utilizing both gain and loss of function assays, we showed that KIF2C promoted HCC cell proliferation, migration, invasion, and metastasis both in vitro and in vivo. Mechanistically, we identified TBC1D7 as a binding partner of KIF2C, and this interaction disrupts the formation of the TSC complex, resulting in the enhancement of mammalian target of rapamycin complex1 (mTORC1) signal transduction. Additionally, we found that KIF2C is a direct target of the Wnt/β-catenin pathway, and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORC1 signaling. Thus, the results of our study establish a link between Wnt/β-catenin and mTORC1 signaling, which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC.

Objective:To observe the clinical efficacy and side effects of injecting different doses of botulinum toxin type A (BTX-A) into children with spastic cerebral palsy (CP) and tiptoe deformity.Methods:A total of 107 children with tiptoe deformity resulting from CP were divided into group A ( n=35), group B ( n=36) and group C ( n=36) using a random number table. Group A received 3u/kg injections of BTX-A, group B received 4u/kg injections and group C received 5u/kg. The injections were guided by color Doppler ultrasound and followed by 4 courses of rehabilitation therapy. Before and 1, 3 and 6 months after the treatment, the modified Tardieu scale (MTS) was used to assess gastrocnemius spasms, while sections D and E of gross motor function scale 88 (GMFM-88) and the pediatric balance scale (PBS) were used to evaluate motor functioning and balance. Any side effects were also observed. Results:After the treatment, improvement was observed in all of the measurements, though there were no significant differences in the degree of improvement nor in the incidence of side effects among the three groups.Conclusions:There is no significant difference in clinical efficacy or side effects involved in using different doses of BTX-A to treat tiptoe deformity in children with spastic cerebral palsy. The recommended dosage is therefore 3u/kg.

Objective:To understand the current status of clinical guidelines and consensus for lung cancer chemotherapy, evaluate and analyze the quality of lung cancer chemotherapy treatment guidelines, and provide references for the revision and improvement of lung cancer chemotherapy clinical decision-making and guidelines.Methods:Search Pubmed, EMbase, Cochrane Library (Cochrane Library), China Knowledge Network, Wanfang Database, China Biomedical Literature Database and other related databases and clinical practice guidelines related to lung cancer chemotherapy, and screen the literatures according to the established inclusion exclusion criteria.
