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 gut microbiota regulation combined with exercise rehabilitation on non-motor symptoms and neurological function in Parkinson's disease patients.Methods A total of 154 Parkinson's disease patients admitted to our hospital from January 2022 to January 2024 were selected as the subjects of the study.Using a random number table,these 154 patients were evenly divided into a control group and a treatment group,with 77 patients in each group.Both groups received standard treatments,but the control group also underwent exercise rehabilitation therapy,while the treatment group received probiotic supplementation and exercise rehabilitation therapy.The effectiveness of the two groups was then compared.Results Following the 12 weeks,24 weeks therapeutic regimen,The treatment group showed significantly better outcomes(P<0.05).Clinically meaningful reductions were observed in Hoehn-Yahr staging,alongside decreased scores on standardized instruments assessing psychiatric symptoms HAMA,HAMD,SCOPA-AUT,UPDRS Ⅰ-IV and PDSS(P<0.05).Concurrently,the study group exhibited enhanced MMSE(P<0.05).Fecal microbiome analyses revealed a favorable ecological shift characterized by increased colonization of beneficial genera Bifidobacterium and Lactobacillus,with concomitant suppression of pathobionts Enterococcus and Enterobacteriaceae.Gait analysis revealed increased step length,speed,and frequency in the treatment group(P<0.05).Conclusion Patients with Parkinson's disease who received probiotics combined with exercise rehabilitation treatment could effectively improve non-motor symptoms and neurological function,while promoting the balance of intestinal flora,and reduce clinical symptoms.

Objective:To investigate the relationship between the E2 and E4 alleles of apolipoprotein E (apoE) gene and myocardial infarction (MI) in type 2 diabetes Mellitus (T2DM) patients, and to explore the relationship between apoE polymorphism and blood lipid metabolism.Methods:This case control study was conducted from August 2016 to March 2020 in China-Japan Friendship Hospital, 3 459 inpatients with T2DM were included including 3 044 patients without MI (T2DM group) and 415 patients with MI (T2DM+MI group). Real time fluorescent quantitative PCR was used to detect apoE polymorphism. Automatic biochemical analyzer was used to detect lipid levels. Logistic regression analyses were performed to determine the association of apoE with risk of MI in patients with T2DM.Results:(1) The frequency of E4 allele in T2DM+MI group (12.29%, 102/830) was significantly higher than in T2DM group (9.13%,556/6 088), while the frequency of E2 allele in T2DM+MI group (7.35%,61/830) was significantly lower than that in T2DM group (8.21%,500/6 088), P=0.012. Logistic regression analyses showed that E4 allele carrier (E3/E4+E4/E4) faced a higher risk for MI in T2DM patients ( OR=1.48, 95% CI 1.14-1.92, P=0.003), while E2 allele carrier(E2/E3+E2/E2)did not face a higher risk of MI in T2DM patients ( OR=0.88, P=0.642). (2) The levels of apoE polymorphism and blood lipid: The levels of TC, LDL-C and apoB increased in the order of E4 allele, wild type and E2 allele ( P<0.05). The levels of HDL-C, apoA1 and apoE decreased in the order of E4 allele, Wild type and E2 allele ( P<0.05). Conclusion:The E4 allele is a risk factor for MI in T2DM patients, and apoE polymorphism can affect blood lipid level in this patent cohort.

Objective:To explore the effect on cardiopulmonary function of early rehabilitation after lung transplantation.Methods:Forty patients undergoing lung transplantation were randomly divided into an observation group and a control group, each of 20. Both groups received routine rehabilitation treatment, psychological counseling and health education about rehabilitation, medications and nutrition. The observation group was additionally given systematic early lung rehabilitation treatment as soon as their vital signs were stable after the operation. It included body position transfers, aerobic training, resistance training and breathing training 3 to 5 times a week for 4 weeks supervised by physical therapists. The control group were informed about methods of aerobic training, respiratory training and airway clearance but carried them out by themselves. The percentage of forced expiratory volume (FVC%), FVC in the first second (FEV1%, ) and FEV1%/ FVC% of the two groups were evaluated using a bedside lung function instrument before the lung transplantation and after 4 weeks of treatment. The six-minute walking distances (6MWDs) of the two groups were compared and their facility in the activities of daily living was evaluated using the modified Barthel index (MBI).Results:Before treatment, there was no significant difference in the average FEV1%, FVC%, FEV1%/FVC%, 6MWD or MBI ratings between the two groups. After the 4 weeks of treatment, both groups showed significant improvement in all of those measurements, on average. The observation group′s averages were, however, significantly better than those of the control group.Conclusion:Early rehabilitation after lung transplantation helps to improve cardiopulmonary function and promote a better quality of life.

BACKGROUND: The gold nanoparticles have a killing effect on tumor cells.OBJECTIVE: To investigate the influence of gold nanochain on Hep-2 cells proliferation of human laryngeal carcinoma.METHODS: The gold nanochain was prepared by a glucose synthesis method and added into the culture cells with different concentrations (10%, 25%, 50%, 75%, 95%) to test the influence on proliferation of in vitro cultured Hep-2 cells. The endocytosis and exocytosis of transmembrane when gold nanochain attached to Hep-2 cells were observed by electron microscopy.RESULTS AND CONCLUSION: The gold chain at high concentrations (75%, 95%) exhibited inhibitory effects on the proliferation of Hep-2 cells, but the influence was not increased with increasing concentration, belonging to a range of non-toxic. Gold nanchain can enter into Hep-2 cells after 8 hours of co-culture and leave cells after 48 hours, indicating gold nanoparticles chain can enter and leave Hep-2 freely.

OBJECTIVE: This study aimed to analyze the expression of epidermal growth factor receptor (EGFR), Ki67 and p16 in human middle ear cholesteatomas and to investigate the correlation between its expression and the ability of erosion of cholesteatoma. METHOD: The specimens from the acquired middle ear cholesteatoma tissue of 30 cases and 21 external ear canal skin samples from patients and 17 external ear canal skin samples from healthful men were taken intraoperatively. Their expression was examined by immunohistochemical SP method. Then we scanned it into a computer by an image scanner and quantified the gray of them using commercial software. RESULT: The percent of positive expression of EGFR, Ki67 and p16 in middle ear cholesteatoma were 70.0%, 60.0%, 46.7%. Their expression tended to the increased greatly compared with the skins of the control groups. There was not correlation between the expression of EGFR, Ki67 and p16 (P > 0.05). It showed statistically significant correlation between expression of EGFR and the ability of erosion of middle ear cholesteatoma (P < 0.01). There was correlation between the expression of Ki67 and the ability of erosion of middle ear cholesteatoma too (P < 0.01). But there was not correlation between the expression of p16 and the ability of erosion of middle ear cholesteatoma (P > 0.05). The expression of EGFR, Ki67, p16 in all epithelial layers of middle ear cholesteatoma were abundantly stained, especially in the basal and spinous layers. Only the basal layer were slightly stained in control groups. CONCLUSION The expression of EGFR, Ki67, p16 in middle ear cholesteatoma was significantly high-er compared with the skin of external auditory of cholesteatoma patients and healthful peoples. There was correlation between the expression of EGFR or Ki67 and the ability of erosion of middle ear cholesteatoma. It means that EGFR, Ki67 and p16 play a key role in the hyperproliferation middle ear cholesteatoma.
