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 systematically review the effect of dual-task training (DTT) on mobility and balance in stroke patients. MethodsCNKI, Wanfang Data, VIP, PubMed, Web of Science, Embase and Cochrane Library were searched for randomized controlled trials (RCT) on DTT in stroke rehabilitation from inception to June, 2025. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool and the PEDro scale. Meta-analysis was performed using RevMan 5.4. ResultsA total of eleven RCT involving 517 stroke patients were included, and the scores of PEDro scale were four to eight. DTT was more effective on the score of Fugl-Meyer Assessment-Lower Extremity (MD = 3.70, 95%CI 1.88 to 5.53, P < 0.001) and Berg Balance Scale (BBS) (MD = 3.04, 95%CI 1.58 to 4.49, P < 0.001), fall incidence (OR = 0.32, 95%CI 0.11 to 0.87, P = 0.025), gait speed under a single-task condition (MD = 0.08, 95%CI 0.03 to 0.12, P = 0.002), gait speed under a dual-task condition (MD = 0.13, 95%CI 0.10 to 0.16, P < 0.001), Timed Up and Go Test time (MD = -2.78, 95%CI -3.85 to -1.72, P < 0.001), and score of modified Barthel Index (MD = 4.77, 95%CI 1.88 to 7.66, P = 0.001). Subgroup analysis indicated that motor-motor DTT was more effective than cognitive-motor DTT on BBS scores and single-task gait speed. ConclusionsDTT can improve mobility and balance in stroke patients, especially with motor-motor tasks.

Objective:To investigate the value of 24 h urinary aldosterone(24 h-UAC) measurement by liquid chromatography-tandem mass spectrometry(LC-MS/MS) in the subtype classification of primary aldosteronism(PA).Methods:A total of 86 patients with PA, including 51 with unilateral primary aldosteronism(UPA) and 35 with bilateral primary aldosteronism(BPA), were enrolled in the Department of Endocrinology and Metabolism at West China Hospital between January 2018 and December 2022. Plasma aldosterone concentration(PAC), plasma renin concentration(PRC) and 24 h-UAC were measured by LC-MS/MS. 24-hour urinary electrolytes and 24-hour urinary creatinine(24 h-UCR) were also measured. The diagnostic value of 24 h-UAC in PA subtype classification was evaluated using receiver operating characteristic(ROC) curve analysis. Multivariate logistic regression analysis was conducted with PA subtypes as the dependent variable(UPA=1, BPA=0) to establish a diagnostic model for differentiating unilateral from bilateral lesions, and its performance was compared with published Chinese classification models. Results:There were no statistical differences between the UPA and BPA groups in terms of age, gender, BMI, systolic and diastolic blood pressure, 24 h urinary potassium, sodium, chloride, 24 h-UCR and PRC( P<0.05). The lowest plasma potassium level was significantly lower in the UPA group than in the BPA group, while PAC, 24 h-UAC, aldosterone-renin ratio(ARR), and 24 h-UAC/UCR were significantly higher( P<0.05). The detection rate of typical adenomas on imaging also showed a significant difference between the two groups( P<0.05). The area under the ROC curve(AUC) of 24 h-UAC for differentiating UPA from BPA was 0.829(95% CI 0.733-0.902), with an optimal cut-off value of 15.4 μg/24 h, yielding a sensitivity of 68.63% and a specificity of 88.57%( P<0.001). At a cut-off value of 24.5 μg/24 h, specificity reached 100%, with a sensitivity of 27.45%. Multivariate analysis indicated that a combined model incorporating 24 h-UAC, the lowest plasma potassium level, and imaging findings of typical adenomas significantly improved diagnostic accuracy for PA subtyping, achieving a specificity of 91.43%. Compared with the existing Chinese modified Küpers scoring model and CONPASS prediction model, this model demonstrated higher diagnostic efficiency, a lower missed diagnosis rate, and a misdiagnosis rate intermediate between the two. Conclusion:The 24 h-UAC in UPA patients is significantly higher than in BPA patients, making it a valuable marker for PA subtype classification. A predictive model combining 24 h-UAC, the lowest plasma potassium level, and imaging evidence of typical adenomas demonstrated high diagnostic accuracy for PA subtype classification and may provide valuable guidance for clinical decision-making.

Objective To construct a nursing follow-up checklist for patients undergoing autologous hematopoietic stem cell transplantation,providing a basis for postoperative follow-up care.Methods Using evidence-based methods,the literature from major guide websites and databases using Chinese and English search terms was retrieved,and their quality was evaluated.The relevant items were extracted,and a first draft was formed.15 experts were selected in relevant fields from 14 tertiary hospitals in 13 provinces,cities,and autonomous regions across the country for Delphi inquiry.The nursing follow-up checklist was revised again based on expert opinions and clinical practice.The nursing follow-up checklist was initially applied and then revised again to form the final draft.Results 15 experts include 12 undergraduate and 3 master's degree holders.The positivity coefficients of the 2 rounds of inquiry were 100％;the authority coefficients of the experts were 0.815;the Kendall coefficients were 0.119 and 0.144,respectively;the differences were statistically significant(P＜0.001).The final nursing follow-up checklist was formed,which includes 6 primary indicators,including physiological status,psychological status,social and family support,living conditions,disease knowledge,and laboratory tests.19 patients(95％)found the follow-up content to be comprehensive.The follow-up nurses's satisfaction rate exceeded 85％.There were 27 secondary indicators and 61 tertiary indicators,with coefficients of variation of all indicators less than 0.25.Conclusion The nursing follow-up checklist is scientific,reliable,and practical,which can provide a basis for clinical nursing staff to follow up and comprehensively manage patients after autologous hematopoietic stem cell transplantation.

Objective To observe the effects of wheat grain moxibustion on the hippocampal ERK/CREB-BDNF/TrkB signaling pathway and neurotransmitters in rats with perimenopausal depressive disorder(PDD);To explore its mechanism in treating PDD.Methods Totally 24 female SD rats were randomly divided into sham-operation group,model group,Western medicine group and wheat grain moxibustion group,with 6 rats in each group.The PDD rat model was established by bilateral ovariectomy and chronic unpredictable mild stress.The wheat grain moxibustion group received moxibustion at the"Zhongwan","Xiawan","Qihai","Guanyuan"acupoints,with a conical moxa cone for intervention,6 cones per acupoint;the Western medicine group was given fluoxetine hydrochloride solution 1.8 mg/kg by gavage,once a day,for consecutive 21 d.Before and after modeling and after intervention,the body mass,sucrose water preference rate and immobility time in the forced swimming test of the rats were recorded;Transmission electron microscopy was used to observe the synaptic structure in hippocampal tissue;ELISA was used to detect the expressions of 5-HT,GABA and Glu in hippocampal tissue;Western blot was used to detect the expressions of ERK,p-ERK,CREB,p-CREB,BDNF and TrkB proteins in hippocampal tissue.Results Compared with the sham-operation group,the body mass and sucrose water preference rate of the model group decreased,and the immobility time in the forced swimming test was prolonged(P<0.01);the number of synaptic vesicles in hippocampus decreased,the thickness of the postsynaptic density decreased,the aggregation of transduction-related proteins decreased,the synaptic cleft increased;the contents of 5-HT and GABA in hippocampal tissue decreased,the content of Glu increased,and the expressions of p-ERK,p-CREB,BDNF and TrkB proteins decreased(P<0.01).Compared with the model group,the body mass and sucrose water preference rate of the rats in Western medicine group and wheat grain moxibustion group increased,and the immobility time in the forced swimming test was shortened(P<0.01);the area of the postsynaptic density in the hippocampus increased,the synaptic cleft reduced,the contents of 5-HT and GABA in hippocampal tissue increased,the content of Glu decreased,and the expressions of p-ERK,p-CREB,BDNF and TrkB proteins increased(P<0.01).Conclusion Wheat grain moxibustion can effectively alleviate depressive-like behavior in PDD rats,and its mechanism may be related to regulating neurotransmitter expressions and mediating the ERK/CREB-BDNF/TrkB signaling pathway,thereby regulating hippocampal neuroplasticity.

Objective:To construct and validate a predictive model for pathological complete response (pCR) in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy.Methods:This retrospective observational study included 595 patients with stage T2-4 and (or) N+M0 LARC diagnosed in the Cancer Hospital of Chinese Academy of Medical Sciences and the Fourth Hospital of Hebei Medical University who had no metastases, tolerated neoadjuvant therapy, completed neoadjuvant therapy, and had undergone radical surgery after neoadjuvant therapy. The training set comprised 299 patients admitted to the Cancer Hospital of Chinese Academy of Medical Sciences from 2013 to 2018, the internal validation set 155 patients admitted from 2019 to 2023, and the external validation set 141 patients admitted to the Fourth Hospital of Hebei Medical University from 2013 to 2021. They were divided into pCR group and non-pCR groups according to postoperative pathology. Among the 299 patients in the training set, 247 were in the non-PCR and 52 in the pCR group; among the 155 patients verified internally, 113 were in the non-PCR and 42 in the pCR group; and among the 141 patients validated externally, 132 were in the non-pCR and nine in the pCR group. Logistic regression was used for univariate and multifactorial analysis to explore the factors associated with pCR and construct a nomogram prediction model. Receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA) were used to validate the performance of the predictive model.Results:Univariate and multivariate logistic regression analysis showed that carbohydrate antigen 19-9 ( P=0.040, OR=0.97, 95%CI: 0.93-0.99), neutrophil count ( P<0.001, OR=0.66, 95%CI: 0.52-0.84), tumor T stage: Stage IV ( P=0.011, OR=0.22, 95%CI: 0.07-0.70), tumor N stage: Stage I ( P=0.003, OR=0.22,95%CI:0.08-0.60), Stage II ( P<0.001, OR=0.03, 95%CI: 0.01-0.09) and involvement of mesorectal fascia ( P=0.004, OR=0.09, 95%CI: 0.02-0.47) were independent predictors of pCR. In the training set, the area under the receiver operating characteristic curve of the model was 0.92 (95%CI: 0.87-0.96), whereas in the internal and external validation sets, the AUCs were 0.78 and 0.81, respectively. The calibration curve showed that the prediction model had good prediction efficiency in both the training and verification sets. Decision curve analysis showed that the net benefit of the model was largest when the threshold probability was in the range of 5.2% to 89.7% (in the internal and external validation sets, the threshold probabilities were in the range of 15.7% to 92.3% and 2.2% to 84.1%, respectively). Conclusion:The nomogram model constructed in this study showed efficacy in predicting whether patients with LARC will achieve pCR after receiving neoadjuvant chemoradiotherapy.

Objective:To explore the safety and efficacy of laparoscopic-assisted radical surgery in the treatment of metachronous multiple primary colorectal cancer (MCC).Methods:A retrospective analysis was conducted on 27 MCC patients undergoing laparoscopic-assisted radical surgery (laparoscopic group) and 36 MCC patients undergoing open radical surgery (open group) from Jan 2012 to Jan 2022 at the Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences.Results:The laparoscopic group was superior to the open group in terms of intraoperative blood loss [(53.7±111.5) ml vs. (132.5±154.9) ml, t=-2.241, P=0.029], time to first postoperative flatus [(2.2±0.7) days vs. (3.5±0.6) days, t=-7.752, P<0.001], time to first postoperative defecation [(2.9±0.6) days vs. (4.3±0.6) days, t=-8.841, P<0.001], and postoperative hospital stay [(7.2±2.4) days vs. (10.6±3.5) days, t=-4.518, P<0.001]. There were no significant differences between the two groups in terms of operation time, number of lymph nodes dissected, positive rate of specimen margin, resection rate of previous colorectal cancer anastomotic stoma, and incidence of postoperative complications (all P>0.05). Conclusion:Laparoscopic surgery is a safe and minimally invasive alternative to open surgery for MCC patients.

Objective:To explore the factors influencing the success rate of culturing patient-derived gastric and colorectal cancer organoids.Methods:From Feb 2022 to Oct 2023, 398 tumor tissue specimens from patients who underwent gastric cancer and colorectal cancer resection at the Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University, were used for organoid culture. The clinicopathological factors affecting the success rate of organoid culture were analyzed.Results:The overall success rate of organoid culture in this group was 75.1% (299/398), with the success rate of gastric cancer organoid culture being 79.8%(154/193) and that of colorectal cancer being 70.7% (145/205). Different clinicopathological T stage ( χ2=4.765, P<0.05),histological type ( χ2=11.248, P<0.05), and tumor regression grade (TRG) grade after neoadjuvant chemotherapy ( χ2=7.797, P<0.05) were related to the success rate of organoid culture . Multivariate analysis showed that the TRG grade was an independent influencing factor( P=0.040). For colorectal cancer, different pathological T stage ( χ2=5.108, P<0.05), histological type ( χ2=11.270, P<0.05), and TRG grade after neoadjuvant chemotherapy ( χ2=6.797, P<0.05) were related to the success rate of organoidculture . Different from gastric cancer, the results of multivariate analysis of colorectal cancer showed that the histological type was an independent influencing factor ( P=0.018). Conclusions:The pathologic T stage, histological type of tumors, and TRG of cancer patients all have a significant impact on the success rate of establishing tumor organoids. Among them, the TRG grade is an independent influencing factor for the culture of gastric cancer organoids, and the histological type is an independent influencing factor for colorectal cancer organoids.

Objective To compare the success rate and stability of rat models of comorbid chronic pain and depression induced by different doses of complete Freund's adjuvant(CFA).Methods Sixty SD rats were divided randomly into a control group,low-dose CFA group(CFA-L),and high-dose CFA group(CFA-H)(n=20 rats per group).Rats in the CFA-L and CFA-H groups were injected with 50 and 100 μL CFA,respectively,and rats in the control group were injected with 0.9％sodium chloride solution.The general state,body weight,mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were observed at 0,7,14,21,and 28 days after modeling.Depressive behavior was evaluated using the open field test(OFT),forced swim test(FST),and tail suspension test(TST).Glutamate(Glu)and γ-aminobutyric acid(GABA)levels in the anterior cingulate cortex were detected by enzyme-linked immunosorbent assay.Brain-derived neurotrophic factor(BDNF)expression in the anterior cingulate cortex was detected by immunohistochemistry,and pathological changes in the anterior cingulate cortex were observed by HE staining.Results(1)Regarding the general condition of the rats,the left ankle joint and toes were obviously red and swollen in the CFA-L and CFA-H groups on the 7th day after modeling,and the swelling was more severe in the CFA-H group.The redness and swelling of the left hind foot and ankle joint and toes gradually recovered in the CFA-L group on days 14,21,and 28 after modeling,but were still obvious in the CFA-H group,and the water and food intake decreased.(2)The body mass was significantly lower in rats in the CFA-H group compared with those in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05).(3)Regarding pain-related behavior,the MWT and TWL were significantly decreased in the CFA-L and CFA-H groups on the 7th and 14th days after modeling,compared with the control group(P＜0.05,P＜0.05).On day 21 after modeling,MWT was significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),and TWL was significantly lower in the CFA-L and CFA-H groups than in the blank group(P＜0.05,P＜0.05).On day 28 after modeling,MWT and TWL were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05).(4)In terms of depression-related behaviors,the total OFT movement distance was significantly lower in the CFA-H group than in the blank and CFA-L groups on day 7 after modeling(P＜0.05,P＜0.05).The total OFT distance and central dwell time were significantly lower in the CFA-H group than in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05),and the result in the FST and TST were significantly higher than in the blank and CFA-L groups(P＜0.05,P＜0.05).(5)Glu,GABA,and BDNF expression levels were significantly higher in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),while GABA,Glu/GABA,and BDNF levels were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05,P＜0.05).(6)The CFA-L group showed less damage in the anterior cingulate cortex,more pyramidal cells,more arranged cells,clear nucleoli,and a small number of cells with karyokynesis and deep staining.Compared with the CFA-L group,rats in the CFA-H group showed a disordered cell arrangement in the injured area of the anterior cingulate cortex,a large number of pyknotic and hyperchromatic neurons,significantly fewer or absent pyramidal cells,and vacuoles,red blood cells,and neurofibrillary tangles in the interstitial space.Conclusions Injection of CFA 100 μL can be used to establish a rat model of chronic inflammatory pain and depression,showing hyperalgesia,depression-like behavioral changes,changes in levels of Glu,GABA,and BDNF in the anterior cingulate cortex,and pathological changes in the anterior cingulate cortex,consistent with the pathophysiological characteristics of chronic pain and depression.
