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 propose a framework for risk assessment and stepwise management of pulmonary nodules based on existing guidelines and key studies, and to clarify the boundaries for triage, workup escalation, and referral in different detection scenarios. Methods A problem-oriented evidence synthesis approach was used, prioritizing Chinese expert consensus, Fleischner Society Guidelines, British Thoracic Society (BTS) Guidelines, and Lung-RADS. This was supplemented by studies on risk models, imaging measurements, liquid biopsy, tissue sampling, and surgical treatments. This paper is not presented as a formal consensus or a validated clinical pathway. Results A three-tiered framework consisting of basic non-invasive assessment, advanced assessment, and invasive diagnosis was established. It specified the applicable populations, boundaries for the use of risk models, imaging review, management of conflicting results, evaluation of histopathological consistency, and post-intervention follow-up. Liquid biopsy, genetic testing, and artificial intelligence were defined as investigational or adjunctive tools. Conclusion This framework can serve as a preliminary reference for multidisciplinary teams in developing local protocols. It cannot replace applicable guidelines, pathological diagnosis, shared decision-making with patients, or real-world validation.

Objective To construct a predictive model for clinical pregnancy outcomes in frozen-thawed embryo transfer(FET)cycles in women with advanced maternal age(age≥35 years)and to analyze its influencing factors.Methods A retrospective analysis was conducted on the clinical data of 2717 older patients who underwent FET treatment at the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2023.These Patients were divided into a clinical pregnancy group(n=851)and a non-clinical pregnancy group(n=1866)based on whether the clinical pregnancy had occurred.The general characteristics and transplantation details of the two groups were compared,and a logistic regression analysis model was constructed.Results The clinical pregnancy rate(CPR)was 31.32%.The CPR for women aged 35-40 years(40.06%)was higher than that for women aged≥40 years(19.35%),with a statistically significant difference(χ2=133.371,P<0.05).The model results showed that the higher anti-Mullerian hormone(AMH)levels(OR=1.053,95%CI:1.012-1.095),the more high-quality blastocysts were transferred(OR=1.704,95%CI:1.143-2.542;OR=2.861,95%CI:1.921-4.262);the more high-quality blastocysts were transferred(OR=2.033,95%CI:1.077-3.836;OR=3.886,95%CI:2.035-7.420),the thicker the endometrial lining on the day of transfer(OR=1.150,95%CI:1.092-1.212)and it could increase the probability of clinical pregnancy.However,for women over 40 years of age(OR=0.551,95%CI:0.437-0.694)and secondary infertility(OR=0.704,95%CI:0.552-0.896),the probability of clinical pregnancy would be reduced;ROC curve analysis results showed that the AUC for predicting clinical pregnancy occurrence in the training set and validation set of the predictive model were 0.723(95%CI:0.699-0.748)and 0.726(95%CI:0.689-0.764),respectively,with cutoff values of 0.262 and 0.260 and the model fit was good(P>0.05).Conclusion Female age,AMH level,type of infertility,number of high-quality embryos(cleavage embryos,blastocysts)transferred,and endometrial thickness on the day of transfer are important factors affecting FET cycles in advanced maternal age women.The constructed prediction model based on these factors has a certain predictive ability for clinical pregnancy.

Objective To compare the long-term survival of elderly patients with esophageal squamous cell carcinoma (ESCC) treated with surgical versus non-surgical treatment. Methods A retrospective analysis was conducted on the clinical data of elderly patients aged ≥70 years with ESCC who underwent esophagectomy or radiotherapy/chemotherapy at Sichuan Cancer Hospital from January 2009 to September 2017. Patients were divided into a surgical group (S group) and a non-surgical group (NS group) according to the treatment method. The propensity score matching method was used to match the two groups of patients at a ratio of 1∶1, and the survival of the two groups before and after matching was analyzed. Results A total of 726 elderly patients with ESCC were included, including 552 males and 174 females, with 651 patients aged ≥70-80 years and 75 patients aged ≥80-90 years. There were 515 patients in the S group and 211 patients in the NS group. The median follow-up time was 60.8 months, and the median overall survival of the S group was 41.9 months [95%CI (35.2, 48.5)], while that of the NS group was only 24.0 months [95%CI (19.8, 28.3)]. The 1-, 3-, and 5-year overall survival rates of the S group were 84%, 54%, and 40%, respectively, while those of the NS group were 72%, 40%, and 30%, respectively [HR=0.689, 95%CI (0.559, 0.849), P<0.001]. After matching, 138 patients were included in each group, and there was no statistical difference in the overall survival between the two groups [HR=0.871, 95%CI (0.649, 1.167), P=0.352]. Conclusion Compared with conservative treatment, there is no significant difference in the long-term survival of elderly patients aged ≥70 years who undergo esophagectomy for ESCC. Neoadjuvant therapy combined with surgery is still an important choice to potentially improve the survival of elderly patients with ESCC.

Objective: To investigate the spatio-temporal clustering characteristics of influenza in Ningxia Hui Autonomous Region from 2014 to 2023, so as to provide the basis for strengthening influenza prevention and control. Methods: Data pertaining to influenza cases reported in Ningxia Hui Autonomous Region from 2014 to 2023 were retrieved from the Infectious Disease Surveillance System of the Chinese Disease Prevention and Control Information System, including age, sex, current residence, onset date, and reporting date. The seasonal incidence of influenza was analyzed using seasonal index. The spatio-temporal clustering characteristics of influenza were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 377 influenza cases were reported in Ningxia Hui Autonomous Region from 2014 to 2023, with a male-to-female ratio of 1.15∶1. The majority were children under 15 years, with 10 950 cases accounting for 53.74%. Influenza was highly prevalent in January, February, March, and December, with seasonal indices of 219.06%, 111.00%, 246.65%, and 366.24%, respectively. The average annual reported incidence was 29.55/100 000, among which Pengyang County, Jinfeng District, Dawukou District, Xiji County, and Litong District had higher average annual reported incidence, at 63.99/100 000, 55.71/100 000, 55.70/100 000, 49.49/100 000, and 49.04/100 000, respectively. Spatial autocorrelation analysis showed that in 2023, there was spatial clustering of influenza cases in Ningxia Hui Autonomous Region (Moran's I=0.333, P<0.05), with a high-high cluster in Jingyuan County, while in other years, the distribution of influenza cases was random (all P>0.05). Spatio-temporal scan analysis showed that from 2014 to 2023, there were four space-time clusters in Ningxia Hui Autonomous Region, including one type Ⅰ cluster in Hongsibao District of Wuzhong City, with the clustering period from January 20 to 26, 2014; and three type Ⅱ clusters, mainly in January, February, March and December, covering one area in Shizuishan City, five areas in Guyuan City, one area in Zhongwei City, three areas in Wuzhong City, and four areas in Yinchuan City. Conclusions From 2014 to 2023, children under 15 years were the primary population affected by influenza in Ningxia Hui Autonomous Region, with distinct spatio-temporal distribution characteristics. The peak incidence occurred during the winter and spring seasons, and the main clustering areas were in the southern regions.

Objective:To compare the clinical effects of restrictive transfusion strategy and liberal transfusion strategy for cardiac valve surgery.Methods:This study employed a prospective, randomized controlled superiority design, enrolling 439 patients undergoing non-emergency cardiac valve surgery with cardiopulmonary bypass at Department of Cardiovascular Surgery, Guangdong Provincial People′s Hospital, Southern Medical University from June 2023 to October 2024 who met the inclusion and exclusion criteria. While all the patients appeared hematocrit (Hct)≤24% or hemoglobin (Hb)≤80 g/L during the cardiopulmonary bypass. A simple random design was adopted to generate a random sequence and participants were randomized into a restrictive transfusion group (restrictive criteria: Hct≤18% or Hb≤60 g/L during cardiopulmonary bypass, and Hct≤21% or Hb≤70 g/L postoperatively) or a liberal transfusion group (liberal criteria: Hct≤24% or Hb≤80 g/L during cardiopulmonary bypass and Hct≤30% or Hb≤100 g/L postoperatively). If Hb or Hct fell below the respective thresholds, 2 units of red blood cells were transfused, followed by re-evaluation. If levels remained below the threshold, an additional 2 units were transfused until the criteria were met. The primary outcome was a composite of postoperative 3-month mortality, infection, ischemic events, and new-onset renal failure requiring dialysis. Secondary outcomes included blood product utilization, length of stay in the ICU and so on. Intergroup comparisons were performed using independent sample t-test, Mann-Whitney U test, χ2 test, or Fisher′s exact test, and analyses were conducted using a binary multivariable Logistic regression model. Results:A total of 439 patients were included in this study. The restrictive roup included 221 patients, including 75 males and 146 females, aged ( M(IQR)) 57.0 (14.0) years (range: 21 to 76 years). The liberal group included 218 patients, including 67 males and 151 females, aged 56.0 (20.0) years (range: 19 to 74 years). No statistically significant difference was observed in the incidence of primary outcome (restrictive group: 10.9%(24/221) vs. liberal group: 9.6%(21/218), χ2=0.180, P>0.05), 2 patints in the restrictive group died and 3 patints in liberal group died ( P=0.684). The transfusion rate was significantly lower in the restrictive group(19.0%(42/221) vs. 100%(218/218), P<0.01), with no significant differences in other secondary outcomes (all P>0.05). Subgroup analysis revealed an interaction between sex and transfusion strategy ( P=0.023), suggesting that using liberal transfusion strategy in male patients might increase the risk of the primary outcome. Conclusion:The mid-term results do not show that the restrictive transfusion strategy is superior to the liberal transfusion strategy in reducing the incidence of postoperative outcome events in patients undergoing cardiac valve surgery.

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.

Objective To construct an MRI radiomics model of cerebral damage following carbon monoxide(CO)poisoning.Methods Ninety patients with CO poisoning and 70 healthy controls(HC)were scanned by structural MRI.All patients were randomly divided into training set(n=128)and test set in a ratio of 8∶2.The radiomics features of 9 regions of interest(ROI)were automatically extracted,and each ROI was subjected to 5-fold cross-validation and 9 different types of classifiers to construct a diagnostic model.Receiver operating characteristic(ROC)curve and decision curve analysis(DCA)were used to evaluate the diagnostic efficacy and clinical value of the model.Results The model based on the radiomics features of the whole brain gray matter(GM)and the left globus pallidus(LGP)had better diagnostic efficacy and clinical application value.The area under the curve(AUC)in the training set and the test set were 0.813,0.815 and 0.806,0.806,respectively.Conclusion The GM-based radiomics model can effectively diagnose cerebral damage following CO poisoning.

OBJECTIVE: To explore effectiveness of TiRobot-assisted screw implantation in the treatment of coracoid process fractures of the scapula. METHODS: A retrospective analysis was conducted on the clinical data from 24 patients with coracoid process fractures of the scapula admitted between September 2019 and January 2024 and met selection criteria. Among them, 12 patients underwent TiRobot-assisted screw implantation (robot group) and 12 underwent manual screw implantation (control group) during internal fixation. There was no significant difference ( P>0.05) in baseline data such as gender, age, body mass index, disease duration, cause of injury, coracoid process fracture classification, and proportion of patients with associated injuries between the two groups. The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, coracoid process fracture healing time, and complications were recorded and compared, as well as pain visual analogue scale (VAS) score, and Constant-Murley score at last follow-up. RESULTS: The intraoperative blood loss and incision length in the robot group were significantly lower than those in the control group ( P<0.05); however, there was no significant difference in operation time and hospital stay between the two groups ( P>0.05). All patients were followed up 8-27 months (mean, 17.5 months), and the difference in follow-up time between the two groups was not significant ( P>0.05). At last follow-up, the VAS score for shoulder pain in the robot group was signifncatly lower compared to the control group, and the Constant-Murley score was significantly higher ( P<0.05). In the robot group, 16 screws were implanted intraoperatively, while 13 screws were implanted in the control group. Radiographic re-evaluation showed that the excellent and good rate of screw implantation was higher in the robot group (93.8%, 15/16) than in the control group (61.5%, 8/13), but the difference in the precision of screw implantation between the two groups was not significant ( P>0.05). Four patients in the robot group and 1 in the control group achieved double screws fixation; however, the difference in achieving double screws fixation between the two groups was not significant ( P>0.05). All fractures healed in both groups with 1 case of malunion in the control group. There was no significant difference in healing time between the two groups ( P>0.05). During follow-up, 1 patient in the control group experienced screw loosening and displacement. There was no significant difference in the incidence of screw loosening and fracture malunion between the two groups ( P>0.05). CONCLUSION Compared with manual screw implantation, TiRobot-assisted minimally invasive treatment of coracoid process fractures of the scapula can reduce intraoperative blood loss, shorten incision length, alleviate pain, and obtain better promote shoulder joint functional recovery.

OBJECTIVE: To investigate the effectiveness of 5G remote robotic surgery in the treatment of pelvic fractures. METHODS: A retrospective analysis was conducted on the clinical data of 160 patients with pelvic fractures admitted between July 2023 and June 2024 who met the selection criteria. Among these patients, 80 underwent internal fixation surgery with the assistance of 5G remote robotic surgery (5G group), while 80 received local robotic surgical assistance (control group). Baseline characteristics, including gender, age, body mass index, disease duration, cause of injury, and fracture classification, were compared between the two groups, and no significant difference was found ( P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, maximum residual displacement postoperatively, quality of fracture reduction, incidence of complications, Majeed pelvic function score and classification at last follow-up were recorded and compared between the two groups. RESULTS: In the 5G group, 180 screws were implanted during surgery, while 213 screws were implanted in the control group. The 5G group demonstrated significantly reduced intraoperative blood loss and shorter incision length compared to the control group ( P<0.05). No significant difference was observed between the two groups in terms of operation time or hospital stay ( P>0.05). Radiographic evaluation revealed excellent and good reduction rates of 98.8% (79/80) in the 5G group and 97.5% (78/80) in the control group, while excellent and good screw placement accuracy rates were 98.3% (177/180) in the 5G group and 95.8% (204/213) in the control group. No significant difference was found between the two groups in maximum residual displacement, reduction quality, or screw placement accuracy ( P>0.05). All patients were followed up 7-16 months (mean, 11.3 months), with no significant difference in follow-up duration between the groups ( P>0.05). No perioperative or follow-up complication, such as wound infection, iatrogenic fractures, iatrogenic neurovascular injury, screw loosening or breakage, or nonunion, were observed in either group. The control group exhibited a worse degree of gait alteration compared to the 5G group ( P<0.05), while no significant difference was found in incidences of squatting limitation or persistent pain ( P>0.05). At last follow-up, no significant difference was observed between the groups in Majeed pelvic function scores or grading ( P>0.05). CONCLUSION Compared with the local surgery group, 5G remote robotic surgery supported by remote expert technical guidance demonstrated smaller incision lengths, less intraoperative blood loss, and fewer postoperative complications, and was shown to be a precise, minimally invasive, safe, and reliable surgical method.
