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.

ObjectiveTo evaluate the clinical efficacy and safety of Jingmaiyan granules （composed of Lonicerae Japonicae Flos， Sedi Herba， Paeoniae Radix Rubra， Moutan Cortex， Rhei Radix et Rhizoma Praeparata， and Glycyrrhizae Radix et Rhizoma） combined with external application of Jinhuang Ointment in treating acute-stage blood heat stasis type superficial thrombophlebitis （ST） of lower extremities， and to explore their effects on hemorheology and serum inflammatory factors. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 124 patients with lower extremity ST were randomized into two groups（62 cases in each group）. The control group received external application of Jinhuang ointment and oral placebo treatment， while the observation group received external application of Jinhuang ointment and oral Jingmaiyan granules. Both groups were treated for 2 weeks. The clinical symptom scores， therapeutic efficacy of traditional Chinese medicine （TCM） syndrome， pain visual analog scale （VAS） scores， hemorheological indices ［including whole blood high-shear， medium-shear， and low-shear viscosity， as well as plasma viscosity （PV）］， and inflammatory factors ［C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）］ were compared before and after treatment. ResultsAfter 2 weeks of treatment， the total effective rate in the observation group （98.3%， 60/62） was significantly higher than that in the control group （83.8%， 52/62）， with a statistically significant difference （Z=3.512 1， P<0.05）. Compared with pre-treatment scores， the scores for skin color， skin temperature， swelling， pain， and cord or nodules were significantly reduced in both groups （P<0.05）， with more pronounced improvement in the observation group （P<0.05）. Additionally， compared with pre-treatment levels， the whole blood viscosity （low-， medium-， and high-shear） significantly improved in both groups after treatment （P<0.05）， with more marked improvement in the observation group （P<0.05）. Furthermore， the plasma viscosity， CRP， IL-6， and TNF-α levels were significantly reduced in both groups after treatment （P<0.05）， with more pronounced improvement observed in the observation group （P<0.05）. ConclusionThe combination of external application of Jinhuang ointment and oral Jingmaiyan granules effectively improves clinical symptoms， hemorheological abnormalities， and inflammatory responses in patients with acute stage blood heat stasis type ST of lower extremities. The treatment is safe and holds clinical promotion value.

ObjectiveTo investigate the influencing factors for traditional Chinese medicine （TCM） syndromes of primary liver cancer， and to provide a theoretical basis for the TCM syndrome differentiation and standardized treatment of liver cancer. MethodsTCM syndrome differentiation was performed for 415 patients who were admitted to Shanxi Institute of Traditional Chinese Medicine and were diagnosed with primary liver cancer based on pathological or clinical examinations from January 2019 to December 2023. The chi-square test was used for comparison of categorical data between groups， and the unordered polytomous logistic regression model was used to investigate the influencing factors for TCM syndromes of liver cancer. ResultsThe common initial symptoms of the 415 patients with primary liver cancer included pain in the liver area （31.81%）， abdominal distension （25.30%）， abdominal pain （15.18%）， and weakness （13.98%）， and the main clinical symptoms included poor appetite （70.84%）， fatigue （69.16%）， pain in the liver area （67.47%）， poor sleep （59.04%）， abdominal distension （53.01%）， and constipation （52.53%）. There were significant differences in TCM syndromes between patients with different sexes， courses of the disease， clinical stages， Child-Pugh classes， presence or absence of intrahepatic and extrahepatic metastasis， and presence or absence of transcatheter arterial chemoembolization （TACE） and radiofrequency ablation （all P<0.05）. The logistic regression analysis showed that male sex was a risk factor for damp-heat accumulation （odds ratio ［OR］=2.036， P=0.048） and the syndrome of spleen-kidney Yang deficiency （OR=5.240， P<0.001）； a course of disease of<1 year was a risk factor for damp-heat accumulation （OR=2.837， P=0.004） and syndrome of Qi stagnation and blood stasis （OR=2.317， P=0.021）， but it was a protective factor against syndrome of spleen-kidney Yang deficiency （OR=0.385， P=0.005）； Child-Pugh class A/B was a protective factor against liver-kidney Yin deficiency （OR=0.079， P<0.001）； intrahepatic metastasis was a risk factor for liver-kidney Yin deficiency （OR=5.117， P=0.003） and syndrome of spleen-kidney Yang deficiency （OR=3.303， P=0.010）； TACE was a protective factor against liver-kidney Yin deficiency （OR=0.171， P<0.001） and syndrome of spleen-kidney Yang deficiency （OR=0.138， P<0.001）； radiofrequency ablation was a risk factor for damp-heat accumulation （OR=4.408， P<0.001） and liver-kidney Yin deficiency （OR=32.036， P<0.001）. ConclusionSex， course of disease， Child-Pugh class， intrahepatic metastasis， TACE， and radiofrequency ablation are the main influencing factors for TCM syndromes of liver cancer.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To evaluate the clinical efficacy of minimally invasive Chevron-Akin osteotomy (MICA) in the treatment of mild to moderate hallux valgus without addressing the proximal projection.Methods:A retrospective analysis was conducted on 31 patients with unilateral mild to moderate hallux valgus who underwent third-generation MICA surgery at Shanghai Sixth People's Hospital from January 2019 to June 2020. Among these patients, 2 were male and 29 were female, with an average age of 41.13±7.8 years (range: 21-64 years). A total of 12 patients had mild hallux valgus, while 19 patients had moderate hallux valgus. The average body mass index (BMI) was 24.37±1.28 kg/m 2 (range: 22.06-26.13 kg/m 2). Preoperative and postoperative foot X-rays were taken at multiple time points, including 1 day, 1.5 months, 3 months, 12 months, and 24 months after surgery. These X-rays were used to assess the medial eminence width (MEW) of the first metatarsal head, the proximal medial projection width (PMRW) of the first metatarsal, the hallux valgus angle (HVA), the intermetatarsal angle (IMA), and the distal metatarsal articular angle (DMAA). Functional improvements and pain relief were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score and the visual analogue scale (VAS). Results:All 31 patients completed an average follow-up period of 25.67±2.35 months (range: 24-31 months). The average operation time was 39.55±7.31 minutes (range: 32-46 minutes). The number of intraoperative fluoroscopy exposures averaged 16.23±2.38 times (range: 13-21 times). At the two-year follow-up, significant improvements were observed in all measured parameters when compared to preoperative values ( P<0.05). The HVA decreased from 35.18°±3.59° before surgery to 10.93°±0.90° after surgery. The IMA was reduced from 11.47°±0.85° to 6.94°±0.65°, and the DMAA decreased from 15.24°±1.13° to 4.31°±0.56°. The MEW decreased from 4.07±0.70 mm to 0.13±0.11 mm. The PMRW, which was measured at one day postoperatively and at the two-year follow-up, decreased from 3.44±0.66 mm to 0.19±0.11 mm. Functional assessments also showed significant improvements ( P<0.05). The AOFAS forefoot score increased from 57.42±3.93 before surgery to 89.52±3.46 at the two-year follow-up. Pain levels, as assessed by the VAS, decreased from 5.68±1.11 preoperatively to 0.77±0.50 postoperatively. At the two-year follow-up, 97% of patients reported excellent satisfaction with the surgical outcome. During the follow-up period, complications included mild numbness around the wound in two cases, metatarsophalangeal joint stiffness in one case, and hallux valgus recurrence in one case, accounting for 3% of the cohort. Conclusion:Third-generation MICA without addressing the proximal projection is an effective procedure for correcting mild to moderate hallux valgus. This technique significantly improves foot function, reduces pain, and leads to high levels of patient satisfaction.

Objective:To identify the change trajectory of intrinsic capacity in people aged ≥50 years in Shanghai and explore the impact of intrinsic capacity trajectory change on overall function and dalily life activities in this population.Methods:The longitudinal data from round 1 to 3 Study of Global Ageing and Adult Health in Shanghai were used. The total intrinsic ability scores from five dimensions of cognition, psychology, sensory, vitality and locomotion were calculated. The censored normal model of group-based trajectory was used to identify the trajectory of intrinsic capacity change over time. Linear regression model and multivariate logistic regression model were used to analyse the effects of different levels intrinsic capacity trajectory on the scores of the WHO Disability Assessment Schedule (WHODAS), the activity of daily living (ADL) and the instrumental activities of daily living (IADL).Results:A total of 2 302 study participants aged ≥50 years with 3 round complete data were included in this study, and 3 levels of intrinsic capacity trajectory were identified, low-level trajectory (9.3%), medium-level trajectory (41.7%), and high-level trajectory (49.0%). Compared with the high-level group, the medium-level and low-level groups had higher WHODAS scores, which increased by 3.578 (95% CI: 2.028-5.129) and 12.620 (95% CI: 9.951-15.289), respectively, and those with more severe disability and those in the low-level group were at higher risk for severe difficulty in ADLs ( OR=12.450, 95% CI: 4.310-35.966) and IADLs ( OR=5.479, 95% CI: 1.311-22.904). Conclusions:Heterogeneity in trajectory of intrinsic capacity exists in people aged ≥50 years in Shanghai. Middle-aged and elderly people with low initial level and rapid decline trajectory of intrinsic capacity are at greater risk for the decline of daily life ability and the increase of disability. It is necessary to strengthen the long-term dynamic monitoring and evaluation of the change trajectory of intrinsic capacity in this population.

Objective:To evaluate the efficacy and safety of Janus kinase (JAK) inhibitors in the treatment of acute severe ulcerative colitis (ASUC).Methods:A retrospective cohort study was conducted. Patients with ASUC treated with JAK inhibitors at the First Affiliated Hospital of Air Force Medical University between January 2021 and March 2024 were enrolled. The primary endpoints were clinical response rate at 1 week and colectomy rate at 90 days. The secondary endpoints were clinical response rate and clinical remission rate at 8 weeks, and adverse events rate at 90 days.Results:A total of 15 patients with ASUC (7 men, 8 women; mean age, 42.47±9.92 years) were included. Eight patients were treated with upadacitinib, and 7 with tofacitinib. The clinical response rate at 1 week was 53.3% (8/15), the colectomy rate at 90 days was 20.0% (3/15), the clinical response rate at 8 weeks was 60.0% (9/15), and the clinical remission rate at 8 weeks was 33.3% (5/15). During the 90-day follow-up, only 1 patient (6.7%) treated with tofacitinib experienced a mild leukopenia.Conclusion:JAK inhibitors are effective for ASUC with the high safety.
