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 This study aimed to investigate the genetic diversity, differentiation, and population structure of Aedes albopictus across different geographical regions in Shandong Province, and to explore the relationship between genetic diversity and geographical distribution. Methods Between July and August 2024, ten Ae. albopictus populations were sampled from seven cities in Shandong Province. Genomic DNA was extracted from individual mosquitoes, and the mitochondrial cytochrome c oxidase subunit I(COⅠ)gene was amplified using PCR and sequenced. The obtained sequences were verified using BLAST and analyzed with MAFFT, MEGA 11, DnaSP v6.12, Arlequin 3.5, PopART 1.7, STRUCTURE 2.3.4 and the R packages adegenet and vegan to assess genetic diversity and population structure. Results A total of 229 COⅠ sequences(662 bp) was obtained, revealing ten variable sites with no insertions or deletions. The overall base composition showed an AT bias of 67.7%. Haplotype analysis identified 11 haplotypes, with Hap2 being the dominant and most widely distributed haplotype across all populations. Neutrality tests showed significant population expansion only in the Rizhao population. Mantel testing result revealed that geographical distance does not significantly impede gene flow. Overall, genetic differentiation among populations was low, indicating frequent gene flow. When combined with additional samples from Shanghai, Fujian, Guangdong, Yunnan, Hainan and Guangxi, STRUCTURE, UPGMA and DAPC analyses revealed two primary genetic clusters of Ae. albopictus. Conclusions Ae. albopictus populations in Shandong Province exhibit frequent gene flow, low genetic differentiation, and relatively low overall genetic diversity. However, the Rizhao population showed signs of recent expansion, highlighting the need for enhanced surveillance and targeted control measures in this area.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Objective:To understand the prevalence of peer-recommended self-HIV testing in men who have sex with men (MSM), and provide clue for identifying key individuals who can promote self-HIV testing.Methods:Data were derived from the self-HIV testing kits application system operated by Shijiazhuang Tongxing Non-Governmental Organization from July 1, 2022 to May 31, 2024. Statistical analysis was conducted by using software SPSS 29.0, and χ2 test was used to analyze differences between groups. Visual analysis of recommendation networks was performed by using software yEd Graph Editor 3.24. Results:A total of 1 574 MSM applied for HIV self-testing kits. The majority of the MSM were unmarried (74.7%), with education level of college or abvoe (65.5%), and employed (53.2%). Among them, 54.8% (862/1 574) reported consistent condom use at each sex in the past three months, while 37.2% (585/1 574) uploaded their HIV test results. Additionally, 53 MSM (3.4%) recommended self-HIV testing to other MSM. Notably, MSM aged ≥30 years and MSM who had occasional condoms use at each sex in the past three months were more likely to recommend self-HIV testing to other MSM. The 53 MSM collectively recommended self-HIV testing to another 740 MSM, the average was 13.9 MSM recommended by 1 MSM. Among MSM who accepted recommendation, 3 HIV-positive cases were identified, indicating that 1 HIV infection was detected by 17.7 recommendations. In the four-round recommendation, 10 MSM participated in more than one round recommendation, all of them were HIV prevention volunteers. Others only participating in one round were common MSM. Eleven MSM recommended self-HIV testing to two or more MSM.Conclusions:Peer-recommendation has high efficiency in the promotion of self-HIV testing, with HIV prevention volunteers serving as the primary force and the common MSM acting as a supportive force. Future efforts should be made to fully use key individuals to promote self-HIV testing.

Objective To observe the value of automated fiber quantification(AFQ)for analyzing relationships of abnormal white matter microstructures and executive dysfunction in children with attention deficit hyperactivity disorder(ADHD).Methods Brain diffusion tensor imaging(DTI)and white matter structure AFQ analysis were prospectively performed on 83 children with ADHD(ADHD group)and 52 healthy children(healthy control[HC]group).The axial diffusivity(AD),radial diffusivity(RD),mean diffusivity(MD),and fractional anisotropy(FA)of complete fiber bundles and respective segments were obtained and compared between groups.Partial correlation analysis was conducted of fiber bundle diffusion parameters and the scores of Swanson Nolan and Pelham-Ⅳ(SNAP-Ⅳ)and behavior rating inventory of executive function(BRIEF)in ADHD group.Receiver operating characteristic curves were applied to assess the efficacy of each diffusion parameter for evaluating ADHD.Results AD and MD of right anterior thalamic radiation(ATR),and AD of right cingulum bundle(CB)in ADHD group were all higher than those in HC group(FWE corrected,all P＜0.000 7).Significant differences of AD of the 54-78 segments of right ATR,MD of the 13-24 and 53-77 segments of right ATR,AD of the 24-26,53-56 and 93-97 segments of right CB,as well as MD of the 72-85 segments of left inferior longitudinal fasciculus(ILF)were found between groups(FWE corrected,all P＜0.001).In ADHD group,AD of 54-78 segments of right ATR were negatively correlated with the attention deficit scores,while of 24-26 segments of right CB were negatively correlated with the emotional control scores.MD of right ATR and some segments,AD of right CB and some segments in ADHD group were positively correlated with the scores of task initiation,planning,organization,monitoring and metacognitive index(all P＜0.05).The area under the curve(AUC)of segmental fiber bundle diffusion parameter and intact fiber bundle diffusion parameter for evaluating ADHD was 0.881 and 0.808,respectively,the former was higher than the latter(Z=2.435,P＜0.05).Conclusion AFQ could be used to analyze relationships of abnormal white matter microstructures and executive dysfunction in ADHD,which could be effectively evaluated based on specific fiber bundle segments.

Objective:To establish a flow cytometric assay for myeloid-derived suppressor cells (MDSC) in human peripheral whole blood and reference intervals for healthy adults in Shanghai region.Method:A whole blood eight-color and twelve-parameter flow cytometric assay was designed, utilizing fluorescently labeled antibodies against CD45, CD3, CD19, CD123, CD56, CD16, HLA-DR, CD33, CD11b, CD14, CD15 and CD20.A total of 246 healthy participants who met the health standards from the health check-ups conducted at the Tongji University Affiliated Shanghai East Hospital between May 8 to December 2, 2024 were enrolled. Peripheral venous whole blood was collected using EDTA-K 2 anticoagulant vacuum tubes for MDSC detection. A single-platform flow cytometry based relative count technique was used to quantify the percentage of each MDSC subpopulation. Kolmogorov Smirnov (K-S) test was used to test the distribution of specimens. Mann-Whitney U test and Kruskal-Wallis (K-W) test were used to evaluate whether reference intervals should be established separately based on gender or age. According to the clinical significance of MDSC, bilateral reference intervals were taken. Non parametric methods were used to take the percentile P2.5 and P97.5 to represent the rank of the lower and upper reference limits, respectively. Results:The results showed that a gating strategy was designed to exclude granulocytes, lymphocyte lineage cells, and natural killer cells. The K-S test results showed that the MDSC in each group of healthy individuals were distributed in a skewed manner. The U test showed significant gender differences ( P0.05) in the distribution of total myeloid-derived suppressor cells (T-MDSC) and polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC). The K-W test showed no significant differences in MDSC among different age groups (21-30 years old, 30-40 years old, 40-50 years old, and 50-60 years old). T-MDSC reference interval is 0.056%-0.485%, PMN-MDSC reference interval is 0.035%-0.406%, Monocytic myeloid-derived suppressor cells (M-MDSC) reference interval is 0.000%-0.221%, early-stage myeloid-derived suppressor cells (E-MDSC) reference interval is 0.004%-0.125%. Reference interval verification was conducted on 20 healthy individuals, with a pass rate of 100%. Conclusion:A whole blood eight-color and twelve-parameter flow cytometric assay was established in this experiment. Based on the flow cytometry single platform method, reference intervals for healthy adults in Shanghai region were established.

Objective To investigate the expression profile of cell adhesion molecular 3(CADM3)on pulmonary endothelial cells,analyze its role in mediating specific adhesion to monocyte,and explore a new mechanism of hypoxia inducing peripheral monocyte infiltration in pulmonary vessels.Methods Human umbilical vein endothelial cells(HUVEC),rat pulmonary vascular endothelial cells(rPEC),and rat aortic endothelial cells(rAEC)were subjected,and divided into normoxic(21%O2)control group and hypoxic(1%O2 or 5%O2)treatment group.Analyzing the transcriptome data of HUVEC exposure to hypoxia for 8 h screened a differentially expressed molecule,CADM3.Cell adhesion experiments,siRNA interference,immunohistochemical assay,Western blotting,and flow cytometry were used to study the role of CADM3 in hypoxia specific high adhesion of HUVEC monocytes.Iron chelator deferoxamine(DFX)and shRNA interference were employed to enhance the expression of HIF-1α,and the effect of HIF-1 transcriptional activity on CADM3 expression was analyzed.Results Hypoxic treatment resulted in enhanced expression of CADM3 in HUVEC,and the expression level reached the peak at 6-8 h after hypoxia,and then decreased.Transfection with siRNA targeting CADM3 decreased the expression of CADM3,and significantly reduced the adhesion rate of hypoxic HUVEC-U937 cells when compared with the negative control group(P<0.05).Compared with the solvent control group,the protein levels of HIF-1α and its target protein STC2 in HUVEC treated with DFX(100 μmol/L)were increased.Transfection with shRNA targeting HIF-1α led the protein levels of HIF-1α and its target protein STC2 decreased,but had no effect on the protein expression of CADM3 in comparison to the negative control group.The protein level and distribution of CADM3 on the cell membrane were increased in hypoxic rPEC.No expression of CADM3 protein was found in the rAEC when compared with rPEC.After treatment with 5 μg/mL LPS,there were no significant changes in HIF-1α,STC2 and CADM3 in rPEC cultured under normoxia or hypoxia.The adhesion rate between hypoxia rPEC with CD11b+cells was the highest,with statistical significance(P<0.01).After incubation with anti-CADM3 antibody,the adhesion of hypoxic rPEC-U937 was significantly decreased compared with the solvent control group(P<0.05).Conclusion Hypoxia specifically induces the expression of CADM3 in pulmonary vascular endothelial cells in a HIF-1-independent manner,and promotes the specific adhesion of pulmonary vascular endothelial cells and monocytes induced by hypoxia.

Objective To investigate the expression changes of serum microRNA(miR)-365a-3p and miR-10a-5p in patients with acute pancreatitis(AP)and their relationship with the severity of the disease.Methods A total of 102 AP patients treated in the hospital from January 2023 to January 2024 were selected as the study group.According to the severity of the disease,the patients were divided into mild acute pancrea-titis(MAP)group and severe acute pancreatitis(SAP)group.A total of 102 healthy people who underwent physical examination in the same hospital during the same period were selected as the control group.Quantita-tive real-time PCR was used to detect the levels of miR-365a-3p and miR-10a-5p.The serum levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and C-reactive protein(CRP)were detected by enzyme-linked immunosorbent assay.Pearson correlation analysis was used to analyze the correlation of serum miR-365a-3p and miR-10a-5p levels with acute physiology and chronic health evaluation(APACHE)Ⅱ score,Ranson score,and biochemical indicators TNF-α,IL-6,and CRP in AP patients.Multivariate Logistic regression was used to analyze the influencing factors of SAP.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of serum miR-365a-3p and miR-10a-5p for AP and SAP.Results The serum levels of miR-365a-3p and miR-10a-5p in the study group were lower than those in the control group(P<0.05).The serum levels of miR-365a-3p and miR-10a-5p in the MAP group were higher than those in the SAP group(P<0.05).The APACHEⅡ score,Ranson score and the levels of TNF-α,IL-6 and CRP in the MAP group were significantly lower than those in the SAP group(P<0.05).Pearson correlation analysis showed that serum levels of miR-365a-3p and miR-10a-5p in AP patients were negatively correlated with APACHEⅡ score and Ranson score(P<0.05).The serum levels of miR-365a-3p and miR-10a-5p in AP patients were negatively correlated with TNF-α,IL-6 and CRP(P<0.05).Multivariate Logistic regression analysis showed that serum TNF-α,IL-6 and CRP were risk factors for SAP(P<0.05),and miR-365a-3p and miR-10a-5p were protective factors for SAP(P<0.05).ROC curve showed that the AUC of miR-365a-3p combined with miR-10a-5p in the diagnosis of AP was 0.832(95%CI 0.777-0.887),which was greater than the AUC of miR-365a-3p alone(0.742,95%CI 0.674-0.810,Z=2.539,P=0.011)and miR-10a-5p alone(0.676,95%CI 0.674-0.810,95%CI 0.602-0.750,Z=4.366,P<0.001).The AUC of the combined diagnosis of SAP was 0.859(95%CI 0.776-0.920),which was greater than the AUC of miR-365a-3p alone(0.733,95%CI 0.637-0.816,Z=2.078,P=0.038),miR-10a-5p alone(0.718,95%CI 0.620-0.803,Z=2.249,P=0.024).Conclusion The expression of serum miR-365a-3p and miR-10a-5p is related to the severity of AP,and the combination of the two is better than single diagnosis of SAP.

OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.
