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 determine the clinical effect of warmed iodophor for preoperative disinfection in elderly patients undergoing laparoscopic hysterectomy.Methods A total of 84 elderly patients who underwent laparoscopic hysterectomy were selected and randomly divided into the room temperature group(disinfected with iodophor at a temperature of 24℃)and the warmed group(disinfected with iodophor at a temperature of 39℃),with 42 cases in each group.The disinfection qualification status,incision infection status,nasopharyngeal temperature,awakening time,adverse reactions,intraoperative blood loss,incision drainage volume,and hidden blood loss of patients in the two groups were compared.Results There was no statistically significant difference in the disinfection qualification rate or incision infection rate between the two groups(P>0.05).At 10 minutes,30 minutes,60 minutes after disinfection and the end of the operation,the nasopharyngeal temperatures of patients in the warmed group were significantly higher than those in the room temperature group(P<0.05).The awakening time of patients in the warmed group was significantly shorter than that in the room temperature group(P<0.05),and the incidences of intraoperative hypothermia and shivering reaction after awakening were significantly lower than those in the room temperature group(P<0.05).There was no statistically significant difference in the intraoperative blood loss or incision drainage volume of patients between the two groups(P>0.05),while the hidden blood loss of patients in the room temperature group was significantly higher than that in the warmed group(P<0.05).Conclusion The iodophor at a temperature of 39℃for preoperative disinfection in elderly patients undergoing laparoscopic hysterectomy can not only ensure the disinfection effect and surgical safety,but also effectively maintain intraoperative body temperature stability,promote postoperative awakening,and reduce hidden blood loss.

Objective:To investigate the clinical value of continuous Bougie tube use in symmetrical three-port laparoscopic sleeve gastrectomy (LSG).Methods:The retrospective cohort study was conducted. The clinical data of 105 patients who underwent symmetrical three-port LSG at The First Hospital of Shanxi Medical University from October 2021 to October 2024 were collected. There were 57 males and 48 females, aged 27(range, 19-59)years. Of the 105 patients, 52 cases with continuous Bougie tube use during the surgery were divided into continuous group, while 53 cases with intermittent Bougie tube use were divided into intermittent group. Observation indicators: (1) surgical situations; (2) complications. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical situations. All 105 patients underwent symmetrical three-port LSG. The operation time was (57±4)minutes versus (76±4)minutes for the continuous group and the intermittent group, volume of intraoperative blood loss was (26±6)mL versus (59±9)mL, time to first out-of-bed activities was (218±8)minutes versus (299±9)minutes, time to first anal exhaust was (19.6±2.9)hours versus (25.8±2.8)hours, visual analogue scale score for pain at 6 hours postoperatively was 2.3±1.0 versus 4.7±1.0, and duration of postoperative hospital stay was (1.5±0.6)days versus (3.1±0.9)days for the two groups, respectively. There were significant differences in the above indicators between the two groups( t=26.92, 22.31, 48.91, 11.15, 13.25, 10.21, P<0.05). (2) Complications. No severe postopera-tive complication occurred in any of the 105 patients. There were 26 cases and 38 cases with nausea and vomiting at 2 hours postoperatively, showing a significant difference between them ( χ2=5.19, P<0.05). Conclusion:Compared to intermittent Bougie tube use, continuous Bougie tube use during symmetrical three-port LSG can significantly shorten operation time and duration of postoperative hospital stay, reduce intraoperative bleeding and postoperative pain, accelerate recovery of patients, and lower the incidence of complications.

Mental health records have been well utilized in various industries or groups both within and outside the mili-tary.However,due to insufficient attention,lack of technology,and poor talent stability,the effectiveness of mental health re-cords is low.This article investigates psychological cadres during a major task to understand the current situation of the establish-ment and use of mental health records in the military.It finds that there is a phenomenon of"building but not flowing,storing but not using",and identifies issues such as inconsistent standards,poor circulation,insufficient content,and disordered manage-ment.Based on this,the article discusses the safeguards and basic content for the construction of mental health records.The dis-cussion concludes that mental health record content should include general information about officers and soldiers,the develop-ment of psychological services,records of psychological rehabilitation(including psychological measurement results,etc.),and other supplementary materials(such as physical health status,personal life history,etc.).It is necessary to standardize mental health measurement,mental health education,mental health training,psychological counseling interviews,psychiatric assess-ment,and psychiatric rehabilitation.Support must be provided in terms of systems,personnel,and technology,and a dynamic management and use mechanism and information security control responsibilities must be implemented.This will promote the or-derly development of military mental health work and,in turn,ensure the mental health of officers and soldiers.

OBJECTIVE To investigate the effect of hyperoside on high glucose-induced excessive proliferation of retinal endo-thelial cells(RECs)and its possible mechanism.METHODS Diabetic retinopathy(DR)models were established in male Sprague-Dawley(SD)rats.DR rats were treated with low-and high-dose hyperoside(DR+L-HY group and DR+H-HY group).Additional-ly,the normal control(NC)group,DR non-intervention(DR)group and DR+calcium dobesilate intervention(DR+CD)group were set up.The differences in the number of RECs in retinal blood vessels were observed and compared among all groups after intervention.In addition,RECs were inoculated into cell culture plates after normal culture and subculture.They were divided into 5 groups according to different treatments:normal glucose(NG)group,high glucose(HG)group,mannitol(MT)group,high glucose+low concentration of hyperoside(HG+H100)group and high glucose+high concentration of hyperoside(HG+H400)group.The activ-ity,cell migration and tubule formation of RECs in each group were detected and compared by CCK-8,cell migration and tubule for-mation assays.Western blot and qPCR were used to detect the expression of NADPH Oxidase 4(NOX4)and thioredoxin interacting protein(TXNIP)in each group.RESULTS The number of RECs in the DR group was significantly increased compared to the NC group(P<0.01).In contrast,the DR+L-HY,DR+H-HY,and DR+CD groups all showed significant decreases in RECs number compared to the DR group(P<0.05,P<0.01),and the reduction of RECs in the DR+H-HY group was significantly greater than that in the DR+L-HY group(P<0.05).Furthermore,the cell activity,migration number and tube formation number of RECs in the HG group were significantly higher than those in the NG group(P<0.05,P<0.01).The protein and mRNA expression levels of NOX4 and TXNIP in the HG group were also significantly higher than those in the NG group(P<0.01).However,the RECs activity,RECs mi-gration number and tube formation number in the HG+H100 group and the HG+H400 group were significantly lower than those in the HG group(P<0.05,P<0.01).The expression levels of NOX4 and TXNIP in both groups were significantly lower than those in the HG group(P<0.05,P<0.01),and the RECs activity,migration number,tube formation number,and the expression of NOX4 and TXNIP in the HG+H400 group were further significantly decreased compared with those in the HG+H100 group(P<0.01).CONCLU-SION Hyperoside could significantly inhibit the high glucose-induced excessive proliferation of RECs.The mechanism may be relat-ed to the inhibition of NOX4/TXNIP activation in high-glucose environment.
