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 analyze the school tuberculosis (TB) outbreaks and preventive treatment in Hefei from 2022 to 2024, so as to provide reference for TB prevention and control in schools. Methods: Data were collected on all school based TB outbreaks occurring during 2022-2024 in Hefei, defined as ≥2 epidemiologically linked TB cases within the same school during a single semester. Statistical analyses were performed using the Chi square test. Results: Close contacts exhibited significantly higher TB incidence (2.88%) and latent mycobacterium tuberculosis infection (LTBI) rates (13.80%) in the school TB outbreaks, compared to non close contacts (0.12% and 2.63%, respectively). Among close contacts, secondary school students showed lower TB incidence (0.48%) and LTBI prevalence (3.42%) than both primary school or younger children (0.68%, 6.95%) and college students ( 0.78% , 6.50%), with statistically significant differences ( χ 2=360.91, 6.37; 791.71, 102.03, all P <0.05). The proportion of LTBI individuals recommended for preventive therapy was higher in primary school or younger groups (98.59%) than in secondary (95.25%) or college students (86.34%) ( χ 2=25.86, P <0.01). However, among those recommended, close contacts had higher uptake (85.82%) and completion rates (87.25%) of preventive therapy than non close contacts (69.63% and 70.57%); similarly, secondary school students demonstrated higher uptake (91.21%) and completion rates (86.45%) compared to primary school or younger (88.57%, 83.87%) and college students (57.28%, 64.08%) ( χ 2=30.52, 26.72; 125.17, 38.84, all P <0.01). Subsequent TB incidence among LTBI close contacts (13.30%) and among those who did not complete preventive therapy (22.73%) were significantly higher than among non close contacts (2.80%, 2.41%), respectively ( χ 2=32.19, 13.87, both P <0.05). Conclusions In school TB outbreaks, close contacts face higher LTBI prevalence and subsequent TB risk than non close contacts. College students show notably low adherence to preventive therapy. It is necessary to take targeted measures to improve the compliance of preventive measures among students.

Objective: To explore the therapeutic effects of different surgical methods for temporomandibular joint disc reduction and anchoring surgery, providing reference for optimizing this surgical procedure. Method: The study was approved by the hospital ethics committee. 173 patients (195 joints) who underwent temporomandibular joint disc repositioning and anchoring surgery were selected for retrospective analysis. Patients were categorized into groups A (traditional preauricular incision-scalpel/tissue scissors anterior attachment release), 35 patients (40 joints), B (traditional preauricular incision-plasma bipolar radiofrequency electrode anterior attachment release), 42 patients (46 joints), C (revised tragus incision - scalpel/tissue scissors anterior attachment release), 50 patients (58 joints), and D (revised tragus incision-plasma bipolar radiofrequency electrode anterior attachment release), 46 patients (51 joints). After a 6-month postoperative follow-up, the differences in maximum mouth opening (MMO), visual analogue scale (VAS), effective rate of joint disc reduction, incidence of preauricular numbness, obvious scars among patients in each group at 1, 3, and 6 months were compared postoperatively. Results: After surgery, the MMO of all four groups of patients initially shrunk and then gradually increased compared to before surgery. At the 1-month follow-up after surgery, the plasma bipolar radiofrequency release (B+D) group had a smaller impact on the patient’s MMO compared to the surgical knife/tissue scissors release (A+C) group (P < 0.05). Postoperative VAS scores for all four groups showed a gradual decrease from pre-operative levels, with the (B+D) group scoring significantly lower in the first month post-surgery compared to the (A+C) group (P < 0.05). Six months post-surgery, the rate of joint disc reduction of the four groups were higher than 95%, with no significant differences observed between the groups (P > 0.05). Patients in the revised tragus incision (C+D) group experienced a lower rate of preauricular numbness compared to those in the traditional preauricular incision (A+B) group (4.59% vs. 12.79%, P < 0.05), The incidence of obvious scars in the (C+D) group was significantly lower than that in the (A+B) group (3.67% vs. 23.26%, P < 0.05). Conclusion The revised tragus incision is superior to traditional preauricular incision in terms of protecting the auriculotemporal nerve and the scars were more inconspicuous. Further, the plasma bipolar radiofrequency electrode is superior to the scalpel/tissue scissors in terms of mouth opening recovery and pain control. For temporomandibular joint disc reduction and anchoring surgery, a modified tragus incision combined with plasma bipolar radiofrequency electrode to release the anterior attachment of the joint disc can be recommended as a surgical option.

Objective To explore the role of miR-1260b targeting activating transcription factor 6β(ATF6β)in osteogenic differentia-tion of human periodontal ligament stem cells(hPDLSCs).Methods The periodontal ligament tissue was scraped from the third molar extracted from the patient with periodontitis,and hPDLSCs were isolated and cultured.The proportions of positive cells of CD34,CD45,CD29,CD90 and CD105 were detected by flow cytometry,and the expression of vimentin and pan-cytokeratin were detected by immunofluo-rescence staining.The cellular luciferase activities of ATF6β-WT and ATF6β-MUT in the miR-1260b mimic+WT/MUT group(transfected with miR-1260b mimic and ATF6β-WT/MUT)and the mimic-NC group(transfected with miR-NC and ATF6β-WT/MUT)were analyzed by the dual luciferase reporter gene assay.In addition,the cells were divided into the miR-1260b mimic group(transfected with miR-1260b mimic alone),the ATF6β-OE group(transfected with the ATF6β overexpression vector alone),the combined group(transfected with miR-1260b mimic and ATF6β overexpression vector simultaneously),and the NC group(transfected with empty vector).Alizarin red S staining and alkaline phosphatase staining were performed on hPDLSCs in the NC group,the miR-1260b mimic group,the ATF6β-OE group and the combined group.Meanwhile,the mRNA expression levels of miR-1260b,ATF6β,Runt-related transcription factor 2(Runx2),osteocalcin(OCN),and osteopontin(OPN)in each group of cells were detected by qRT-PCR.The protein expressions of glucose-regulated protein 78(GRP78),C/EBP homologous protein(CHOP),and protein kinase R-like endoplasmic reticulum kinase(PERK)in each group of cells were detected by Western blot.Results The flow cytometry detection showed that CD29,CD90 and CD105 on the surface of the isolated and cultured cells were positive,while CD34 and CD45 were negative.Immunofluorescence staining showed that vimentin in the cells was positive and pan-cytokeratin was negative,which was in line with the characteristics of hPDLSCs.Luciferase assay showed that miR-1260b mimic could significantly reduce the luciferase activity of ATF6β-WT(P<0.05),but had no significant effect on the luciferase activity of ATF6β-MUT(P>0.05).After alizarin red S staining,the staining of hPDLSCs gradually deepened after 3 days,5 days and 7 days of culture,suggesting an enhanced osteogenic differentiation ability.With the enhancement of osteogenic differentiation ability of hPDLSCs,the expression of miR-1260b in the cells showed a gradually increasing trend,while the mRNA and protein expression levels of ATF6β showed a gradually decreasing trend(P<0.05).The results of alizarin red S staining and alkaline phosphatase staining showed that the proportions of positive area in the miR-1260b mimic group were higher than those in the NC group(P<0.05),while the proportions of positive area in the ATF6β-OE group and the combined group were lower than those in the NC group(P<0.05).The mRNA and protein levels of ATF6β in the miR-1260b mimic group were lower than those in the NC group(P<0.05),while the mRNA and protein levels of ATF6β in the ATF6β-OE group and the combined group were higher than those in the NC group(P<0.05).The mRNA levels of Runx2,OCN and OPN in the miR-1260b mimic group were significantly higher than those in the NC group(P<0.05).The mRNA levels of Runx2,OCN and OPN in the ATF6β-OE group and the combined group were significantly lower than those in the NC group(P<0.05).The protein expression levels of GRP78,CHOP and PERK in the miR-1260b mimic group were significantly lower than those in the NC group(P<0.05).The protein expression levels of GRP78,CHOP and PERK in the ATF6β-OE group and the combined group were significantly higher than those in the NC group(P<0.05).Conclusion miR-1260b can inhibit endoplasmic reticulum stress level and promote osteogenic differentiation of hPDLSCs by targeting ATF6β.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To investigate the clinical characteristics,antimicrobial susceptibility of pathogens,and laboratory test results of patients with Vibrio vulnificus infection.Methods The clinical and etiological data,as well as laboratory tests were reviewed retrospectively for 14 patients with V.vulnificus infection,who were admitted to the 909th Hospital from May 2022 to November 2023.Results Overall,9 of the 14 patients(64.3％)had a history of exposure to seafood or seawater.Six patients(42.9％)had underlying diseases,such as hepatitis,coronary heart disease and diabetes mellitus.Eleven patients(78.6％)had a good outcome,while 3 patients(21.4％)had a poor outcome.A total of 18 strains of V.vulnificus were isolated,including 11(61.1％)strains from wound pus,and 7 strains(38.9％)from blood.V.vulnificus isolates were susceptible to ampicillin-sulbactam,piperacillin-tazobactam,imipenem,meropenem,tetracycline,ciprofloxacin,levofloxacin,trimethoprim-sulfamethoxazole,and chloramphenicol,but only 50.0％,55.6％,and 61.1％of the strains were susceptible to cefazolin,ampicillin,and amikacin,respectively.White blood cell count,neutrophil,C-reactive protein,prothrombin time,fibrinogen,activated partial thromboplastin time,D-Dimer,urea nitrogen,creatinine,uric acid,glutamic-pyruvic transaminase,glutamic oxaloacetic transaminase,lactate dehydrogenase,alkaline phosphatase,creatine kinase,creatine kinase isoenzyme MB,hypersensitive troponin I,myoglobin,procalcitonin,and N-terminal pro-brain natriuretic peptide were significantly increased in patients with V.vulnificus infection.Conclusions Wound pus and blood samples collected simultaneously for microbial culture can improve the detection of V.vulnificus.Early debridement and antibiotic combination therapy are vital for improving patient survival rate.

Objective:To explore the value of ultrasound imaging characteristics combined with clinical indicators in assessing the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC).Methods:A retrospective analysis was conducted for patients who underwent pancreatic contrast-enhanced ultrasound (CEUS) from September 2017 to October 2023 at Peking Union Medical College Hospital and were diagnosed with PDAC based on pathological findings. Various parameters were recorded, including CA19-9 levels, tumor size, location, morphologic features, echogenicity, presence of internal cystic components, dilatation of the main pancreatic duct, peripheral vascular invasion, CEUS characteristics, presence or absence of liver metastasis, and treatment methods. In April 2024, patient survival information was obtained through telephone follow-up or review of medical records. Based on the results of the cox regression model analysis, a nomogram model of the risk of death was developed. The receiver operating characteristic (ROC) curves were applied to evaluate the predictive efficacy of the model. The calibration curves were plotted to evaluate the accuracy of the model, and clinical decision curves were used to evaluate the clinical benefit of the model.Results:This study included a total of 207 patients with PDAC. As of April 2024, 71 patients were alive and 136 died, with a median survival time of 14 months (95% CI: 12 -17). Multivariate analysis confirmed that the elevated CA19-9 ( HR=1.689, 95% CI: 1.102-2.588), tumor size >4 cm ( HR=1.641, 95% CI: 1.159-2.322), taller-than-wide shapes ( HR=1.450, 95% CI: 1.019-2.065), incomplete hypo-enhancement ( HR=1.618, 95% CI: 1.100-2.380), and liver metastasis ( HR=1.687, 95% CI: 1.175-2.423) were independent risk factors for survival in patients with PDAC. A nomogram model was further constructed for 6-month, 12-month and 3-year survival of patients with PDAC. The areas under the ROC curve were 0.679, 0.705 and 0.815, respectively. The calibration curves suggested that the model was more accurate, and the clinical decision curves showed that the model had a better clinical benefit. Conclusion:The combined use of ultrasound imaging characteristics and clinical indicators could effectively predict the prognosis of PDAC patients. Specifically, tumor size >4 cm, taller-than-wide shapes, incomplete hypo-enhancement, elevated CA19-9, and the presence of liver metastasis are correlated with poorer survival outcomes. The nomogram model constructed on the basis of these factors can be used to assess the survival of patients with PDAC.
