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.

Radiation-induced esophageal injury (RIEI) is a frequent complication following radiotherapy for thoracic and head-neck malignancies, which may lead to severe sequelae including esophageal stricture and perforation, adversely affecting patients' quality of life and therapeutic outcomes. With advancements in radiotherapy techniques — particularly the adoption of unconventional fractionation regimens, concurrent chemoradiotherapy, and combined molecular targeted / immunotherapy — the incidence of RIEI has been increasing. In this review, recent advances in understanding the pathogenesis, clinical manifestations, risk factors, and management strategies for RIEI were comprehensively summarized. Current therapeutic approaches have evolved beyond conventional anti-inflammatory and nutritional support to include novel interventions such as targeted therapy, free radical scavengers, and microbiota modulation, etc. Future research should prioritize the development of optimized, individualized prevention and treatment protocols to mitigate RIEI risk and improve patient prognosis.

Objective:To analyze the trabecular bone score (TBS) and its association with muscle health in the postmenopausal population.Methods:It was a cross-sectional study. A total of 214 postmenopausal individuals who underwent dual-energy X-ray absorptiometry testing at the Beijing Research Institute of Sports Science between January and December 2023 were consecutively included. The participants were divided into two groups based on the presence or absence of osteoporosis (OP): 62 cases in the OP group and 152 cases in the non-OP group. All subjects completed body composition assessments and scans of bilateral hip and lumbar spine bone mineral density (BMD)(All the BMD in this study were areal BMD). Demographic data, including age, age at menarche, age at menopause, and fracture history, were also collected. TBS was calculated using the TBS iNsight software. Muscle health indicators included upper limb, lower limb, trunk, and total muscle mass, lean body mass, appendicular skeletal muscle mass index (ASMI), and grip strength. The Pearson correlation analysis was used to determine the relationship between TBS and muscle health indicators, as well as between TBS and the BMD of lumbar spine (L 1-4). Further, multiple linear regression analysis was conducted to explore the independent association between TBS and muscle health indicators. Results:TBS, lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, trunk, whole body in the OP group were all lower than those in the non-OP group [(1.27±0.07) vs (1.35±0.07) score, (36.64±3.45) vs (39.14±3.62) kg, (6.16±0.56) vs (6.44±0.63) kg/m2, (23.87±3.31) vs (25.34±4.33) kg, (3.54±0.47) vs (3.78±0.47) kg, (11.70±1.33) vs (12.68±1.49) kg, (16.57±1.68) vs (17.50±1.69) kg, and (34.91±3.33) vs (37.13±3.47) kg] (all P<0.05). Pearson analysis showed that TBS was positively correlated with lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, whole body (all P<0.05). TBS was negatively correlated with age ( P<0.01). TBS was positively correlated with the BMD of lumbar spine (L 1-4) ( r=0.660, P<0.01). Multiple regression analysis demonstrated that ASMI was positively correlated with TBS ( β=0.284, P<0.01). Conclusion:In the postmenopausal population, individuals with OP have lower TBS. Furthermore, TBS is closely associated with muscle health.

Objective To evaluate the effectiveness of low-volume high-intensity interval training(LV-HIIT)protocols defined by the W'Balance(W'BAL)model in achieving maximal activation of both anaerobic and aerobic energy systems.Methods Twenty-eight national-level athletes(age:20±1 years old;height:174±9 cm;weight:65.1±9.4 kg)completed an incremental exercise test,followed by six supra-critical power(supra-CP)and five sub-CP constant-load tests to determine VO2max,maximal accumulated oxygen deficit(MAOD),critical power(CP),and W prime(W').They then performed three randomly ordered LV-HIIT protocols(each of 4-minute total duration),with a 10-second inter-val for passive recovery between bouts.The protocols consisted of 10s(HIIT10/10),20s(HIIT20/10),and 30 s(HIIT30/10).Exercise intensities were individually prescribed using the W'BAL model.Accu-mulated oxygen deficit(AOD)and net AOD(NAOD)were calculated for each protocol.Results Final 10-s oxygen uptake(VO2)reached 77％,88％,and 89％of VO2max in HIIT10/10,HIIT20/10,and HIIT30/10,respectively(P<0.05).VO2 in HIIT10/10 was significantly lower than in HIIT20/10 and HIIT30/10(P<0.05),with no significant difference between the latter two(P>0.05).AOD did not differ significantly from MAOD among the three protocols(P>0.05),whereas NAOD was significantly lower than MAOD in all cases(P<0.05).Additionally,NAOD in HIIT10/10 was significantly lower than in HIIT20/10 and HI-IT30/10(P<0.05),with no significant difference between the latter two(P>0.05).Conclusion The HIIT20/10 and HIIT30/10 intensity established by the W'BAL model can substantially elicit maximal activation of both anaerobic and aerobic energy systems.While the W'BAL model demonstrates potential for set-ting exercise intensities in LV-HIIT,future studies are necessary to develop specific W'recovery rate models for targeted populations and to refine CP models that are better suited for intermittent exercises.

Objective To compare the effectiveness of the heart rate variability threshold(HRVT),muscle oxygenation threshold(MOT),and their combined threshold(COMT)in predicting the ventila-tory threshold(VT)and lactate threshold(LT).Methods Twenty male athletes at or above the nation-al level were recruited to perform an incremental exercise test to determine VT and LT,during which gas exchange,muscle oxygenation,and heart rate variability were collected.The HRVT,MOT,and COMT methods were then applied,and their predictive validity was evaluated by comparing the correla-tions and agreements between heart rate(HR)and power output(PO)at VT and LT.Results For HR,VT1 showed strong correlation and agreement with MOT1(r=0.958,ICC=0.944)and COMT1(r=0.957,ICC=0.951),with COMT1 having the smallest mean bias(1.4 bpm)and the narrowest limits of agreement(LOA)(-5.4 to 8.2 bpm).Moreover,VT2 demonstrated the highest correlation and agree-ment with COMT2(r=0.985,ICC=0.982),with a mean bias of-0.7 bpm and LOA of-5.0 to 3.7 bpm.Meanwhile,LT showed high correlation and good agreement with COMT2(r=0.884,ICC=0.754)and MOT2(r=0.886,ICC=0.738),with mean biases of-6.8 bpm and-7.3 bpm,and LOA of-17.5 to 3.8 bpm and-17.9 to 3.2 bpm,respectively.For PO,VT1 had the best correlation and agreement with MOT1(r=0.836,ICC=0.808),with a mean bias of-0.2 W and LOA of-11.7 to 11.3 W.VT2 performed best correlation and agreement with COMT2(r=0.910,ICC=0.900),with a mean bias of 2.3 W and LOA of-8.9 to 13.5 W.In LT prediction,MOT2(r=0.736,ICC=0.692)outperformed COMT2(r=0.635,ICC=0.618),with mean biases of-2.6 W and 0.2 W,and LOA of-26.0 to 20.7 W and-26.6 to 27.1 W,respectively.Conclusion All three indicators—HRVT,MOT,and COMT—demonstrates high validity in predicting VT and LT.MOT1 performs best for predicting PO at VT1,while COMT2 shows the highest consistency for predicting both HR and PO at VT2.Howev-er,for LT prediction,MOT2 is more advantageous for predicting PO,whereas COMT2 is more accu-rate for predicting HR.Therefore,method selection should be tailored to the specific threshold type and measurement target.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

Objective:To compare the efficacy of robot-assisted percutaneous reduction and screw fixation versus open reduction and plate fixation via the sinus tarsi approach in the treatment of Sanders types II and III calcaneal fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 82 patients (90 feet) with calcaneal fractures admitted to the Department of Orthopedic Trauma, Beijing Jishuitan Hospital, Capital Medical University from January 2020 to April 2024, including 74 males and 8 females, aged 24-87 years [(46.4±12.1)years]. According to Essex-Lopresti classification, the fractures were classified as tongue-type in 43 patients and joint-collapse-type in 47. According to Sanders classification, 69 feet were classified as type II and 21 as type III. Forty-seven patients (52 feet) were treated with robot-assisted percutaneous reduction and screw fixation (screw fixation group) and 35 (38 feet) with open reduction and plate fixation via the sinus tarsi approach (plate fixation group). The two groups were compared in terms of the operation duration, intraoperative blood loss, length of hospital stay and time to weight-bearing. The width, height, length, B?hler angle and Gissane angle of the calcaneus before surgery and at 1 day after surgery were compared. The Maryland foot and ankle function score, American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot function score, and visual analogue scale (VAS) score at 1, 3 months postoperatively, and at the last follow-up were compared. The incidence of postoperative complications and removal rate of internal fixation were also detected in the two groups.Results:All the patients were followed up for 9-60 months [(30.0±14.5)months]. There was no significant difference in the operation duration between the two groups ( P>0.05). The intraoperative blood loss, length of hospital stay and time to weight-bearing in the screw fixation group were 10.0(10.0, 20.0)ml, 7.0(5.0, 8.0)days and (5.0±0.8)weeks, which were significantly less or shorter than 30.0(20.0, 50.0)ml, 8.0(6.0, 11.0)days and (6.9±0.7)weeks in the plate fixation group ( P<0.05). The width, height, length, B?hler angle and Gissane angle of the calcaneus at 1 day after surgery were (43.4±4.2)mm, (46.2±4.0)mm, (81.6±5.1)mm, 27.1(20.4, 30.4)° and (113.4±10.1)° in the screw fixation group, which were all improved compared with those before surgery [(47.8±4.6)mm, (39.3±4.8)mm, (79.2±5.9)mm, 9.5(0.0,16.5)° and (119.3±13.4)°] ( P<0.01). The width, height, length and B?hler angle of the calcaneus at 1 day after surgery were (41.6±5.7)mm, (48.4±4.8)mm, (83.1±5.7)mm and 27.3(21.3, 31.6)° in the plate fixation group, which were all improved compared with those before surgery [(47.8±5.0)mm, (41.7±5.1)mm, (80.1±5.9)mm and 12.9(7.2,19.8)°] ( P<0.01), with no significant difference in the Gissane angle ( P>0.05). Before surgery and at 1 day postoperatively, no significant differences were found in the width, length, B?hler angle or Gissane angle of the calcaneus between the two groups ( P>0.05), while the height of the calcaneus in the screw fixation group was lower than that in the plate fixation group ( P<0.05). At 1 month after surgery and at the last follow-up, there were no significant differences in the Maryland foot and ankle function score, AOFAS ankle and hindfoot function score, and VAS score between the two groups ( P>0.05). At 3 months after surgery in the screw fixation group, the Maryland foot and ankle function score was (79.7±3.8)points, significantly higher than (74.7±2.8)points in the plate fixation group ( P<0.01); the AOFAS ankle and hindfoot function score was (77.1±5.0)points, significantly higher than (70.1±3.6)points in the plate fixation group ( P<0.01); the VAS score was 1.0(1.0, 2.0)points, significantly lower than 2.5(2.0, 3.0)points in the plate fixation group ( P<0.01). No significant difference was detected in the incidence of postoperative complications between the two groups ( P>0.05). The removal rate of internal fixation was 10% (5/52) in the screw fixation group, significantly lower than 29% (11/38) in the plate fixation group ( P<0.05). Conclusion:Compared with open reduction and plate fixation via the sinus tarsi approach, robot-assisted percutaneous reduction and screw fixation has the advantages of less intraoperative blood loss, shorter hospital stay, earlier weight-bearing exercises, better early functional recovery and pain relief, and lower internal fixation removal rate in the treatment of Sanders types II and III calcaneal fractures.
