Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

To investigate the influencing factors of postoperative complications following thoracoscopic lung resection in elderly patients and to provide a scientific basis for developing preoperative prehabilitation strategies for high-risk elderly populations.

Lung cancer, particularly non-small cell lung cancer (NSCLC), is a leading cause of cancer-related mortality worldwide. In recent years, metabolomics has emerged as a key systems biology approach for analyzing small-molecule metabolites in cells, tissues and organisms. It provides new strategies for early diagnosis and metabolic profiling. Additionally, metabolomics plays a crucial role in studying resistance mechanisms in lung cancer. Tumor cell metabolic reprogramming is a key driving factor in the initiation and progression of lung cancer. Metabolomics studies have revealed how lung cancer cells regulate critical pathways such as energy metabolism, lipid metabolism, and amino acid metabolism to adapt to the demands of rapid proliferation and invasive metastasis. This review summarizes the latest advances in metabolomics research in lung cancer, focusing on the characteristics of metabolic reprogramming, the identification of potential metabolic biomarkers, and the prospects of metabolomics in early diagnosis and the elucidation of resistance mechanisms in lung cancer.

Objective:To explore any effect of 8 weeks of high-intensity interval training (HIIT) on glycemia and pancreatic β-cell function among persons with type 2 diabetes to provide data for optimizing their exercise protocol.Methods:Sixty patients with type 2 diabetes and without a habit of regular exercise were randomly divided into an exercise group ( n=30) and a control group ( n=30). Both groups maintained their daily living habits, except that the exercise group practiced HIIT on a power vehicle ergometer 3 times a week for 8 weeks. Before and after the intervention, the 2-hour oral glucose tolerance test (OGTT) was conducted to evaluate glycemia and pancreatic β-cell function. Body composition was also detected using dual-energy X-ray absorptiometry. Results:After the intervention a significant decrease was observed in the fasting blood glucose, mean blood glucose, glycosylated hemoglobin, blood glucose levels at the end of a 2h OGTT, blood glucose area under the curve and homeostatic model assessment of insulin resistance, as well as waist circumference and abdominal fat content of the exercise group. And there was a significant increase in the homeostatic model assessment of pancreatic β-cell function and disposition index among the exercise group. In the control group no significant differences were observed.Conclusion:Eight weeks of HIIT can improve glycemia and pancreatic β-cell function and reduce abdominal fat among persons with type 2 diabetes. It can be used as an effective rehabilitation protocol.

Objective:To evaluate the diagnostic value of coronary angiography-based fractional flow reserve(caFFR)versus a wire-based fractional flow reserve(FFR)in elderly patients with stable ischemic heart disease.Methods:A total of 168 patients(186 vessels)who underwent a pressure wire(PW)-based FFR measurement from Jan.2015 to Dec.2019 in Beijing hospital were enrolled and analyzed retrospectively.Coronary angiography images and matched steady-state aortic pressure of patients were sent to the core laboratory for caFFR measurement under the blind method.All patients were divided into the non-elderly group(<65 years, n=93)and the elderly group(≥65 years, n=75). The diagnostic value of caFFR was evaluated by using the wire-based FFR cut-off value of ≤0.80 as the reference standard.The correlation and consistency of caFFR and wire-based FFR were analyzed, and compared between the non-elderly and elderly groups.Results:The caFFR had a good correlation and consistency with wire-based FFR in the elderly group( r=0.796, P<0.01). In non-aged versus elderly groups, diagnostic accuracy of caFFR was 91.9% versus 93.1%, diagnostic sensitivity of caFFR was 91.8% vs.93.2%, diagnostic specificity of caFFR was 92.3% vs.93.0%, all P>0.05.The area under the receiver-operating characteristic curve of caFFR had no significant difference between the non-elderly and elderly patients(0.964 vs.0.972, Z=0.00823, 95% CI: -0.037-0.052, P>0.05). Conclusions:The caFFR has a good diagnostic correlation and consistency with wire-based FFR in the elderly group, and caFFR's diagnostic performance in the elderly is similar to that in the non-elderly patients.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective To evaluate the clinical impact of percutaneous coronary intervention (PCI)on prognosis in elderly patients(≥70 years old)with coronary artery chronic total occlusion (CTO). Methods A total of 445 consecutive patients with a angiography-confirmed CTO lesions registered from January 2011 to December 2013 were divided into the elderly group(≥70 years)and the non-elderly group(< 70 years).The primary endpoints measured were defined as the composite outcomes of hospitalization due to angina,re-infarction,heart failure,repeat re-vascularization,and cardiac death at 36 months follow-up. Results The elderly group included 200 patients(44.9%) and the non-elderly group included 245 patients(55.1%).During the follow-up,the proportions of coronary lesion were significantly higher in the elderly group with left main(LM)disease(45, 22.5%),three-vessel disease(166,83.0%)and J-CTO score≥2(64,32.0%)than in the non-elderly group with diseases of LM,three-vessel,and J-CTO score ≥ 2〔(34,13.9%);(180,73.5%);(57, 23.3%),respectively〕(χ2 =5.607,5.782,4.243;P=0.018,0.016,0.039).T he ratio of the patients undergoing PCI-reperfusion therapy of CTO was higher in non-elderly group(109/275,39.6%)than in elderly group(53/222,23.9%)(χ2 =13.891,P<0.001),while CTO PCI success rate was similar between the two groups(38 patients,71.7% vs.90 patients,82.6%,χ2 = 2.541,P= 0.111).The elderly group versus non-elderly group showed that the 3-year cardiac mortality rate was 12.5%(25 patients)versus 3.3%(8 patients)(χ2 =13.677,P<0.011),and the incidence rate of 3-year primary endpoint was 31.5%(63 patients)versus 22.9%(56 patients)(χ2 =4.199,P=0.040).Among the elderly group,patients without CTOs re-vascularized by PCI had a greater tendency toward higher risk of hospitalization due to angina,re-infarction,heart failure,or repeat re-vascularization than patients with CTOs re-vascularized by PCI(34/149,22.8% vs.3/33,9.1%,χ2 =3.143,P=0.076),while they had comparable incidence of 3-year cardiac death(19/149,12.8% vs.5/33,15.2%,χ2 = 0.007,P=0.933).Multivariate analysis revealed that after adjusting for baseline and procedure differences,LM combined with three vessel disease(OR= 3.804,95% CI:1.274 to 11.356,P= 0.017)remained an independent predictor for 3-year cardiac mortality in elderly patients with CTOs. Conclusions Elderly patients with CTO have mostly a serious coronary artery disease and a poor prognosis.Although CTO is re-vascularized by PCI,long-term clinical outcome seems not more to be improved in elderly patients with CTOs.LM combined with three-vessel disease might be an independent predictor for 3-year cardiac mortality in elderly CTO patients.

Objective To analyze the safety and efficacy of coronary rotational atherectomy in elderly patients with coronary heart disease.Methods A total of 107 consecutive patients with coronary artery disease receiving rotational atherectomy from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into an ≥75 years group(n=44)and a ＜75 years group (n=63).We compared the characteristics of rotational atherectomy,peri-procedural complications,instant procedure success rates and 1-year cardiovascular events,including angina,re-infarction,hospitalization due to heart failure,repeat revascularization and cardiac death.Results There was no significant difference in the target coronary vessel,reference vessel diameter,maximal diameter of the burr and ratio of maximal diameter of the burr to reference vessel diameter between the two groups(all P＞0.05).Compared with ＜75 years patients,more ≥75 years patients used 2 burrs(10 cases or 22.7％ vs.4 cases or 6.3％,P =0.013),while there was no significant difference in terms of burr size,rotational time,maximal rotational speed,pre-and post-dilation pressure between the two groups (all P＞0.05).The incidence of peri-procedural complications had no significant difference between the ≥75 years group and the ＜75 years group(8 cases or 18.2％ vs.13 cases or 20.6％,P =0.753).One case of burr entrapment occurred in each group with successful retrieval.The procedure success rate was 96.8％(61 cases)in the ＜75 years group and 100％ in the ≥75 years group(P=0.640).No acute or sub-acute stent thrombosis or urgent coronary artery bypass graft occurred in the two groups during hospitalization.No cardiac death occurred in either group.Conclusions Coronary rotational atherectomy is effective and safe in elderly patients with coronary disease with a high instant procedure success rate.

Objective: To study the prognostic impact of chronic total occlusion (CTO) on non-infarct-related artery (non-IRA) in patients of acute ST-elevation myocardial infarction (STEMI) with emergent primary percutaneous coronary intervention (PCI).
Methods: In this prospective study, a total of 185 consecutive acute STEMI patients received early stage primary PCI in our hospital from 2010-01to 2011-06 were enrolled. The patients were divided into 2 groups:non-CTO group, n=160 and CTO group, n=25. The patients were followed-up for 1 year and the primary endpoint events included the hospitalization for angina, re-MI, heart failure or revascularization and cardiac death.
Results: ①There were more patients with diabetes and three vessel disease in CTO group than those in non-CTO group (40.0%vs 20.0%, P=0.049) and (68.0%vs 36.3%, P=0.003);LVEF in CTO group was lower than non-CTO group (40.0 ± 20.1%vs 51.3 ± 15.3%, P<0.05).②The cardiac mortalities at 6-month and 1-year followed-up period were higher in CTO group than those in non-CTO group (26.3%vs 6.1%, P=0.013) and (31.6%vs 8.4%, P=0.010);1-year primary endpoint events were higher in CTO group (52.6%vs 16.8%, P=0.001). ③Multivariate regression analysis revealed that non-IRA combining CTO (HR=3.889, 95%CI 1.239-4.206, P=0.020), cardiac shock (HR=3.229, 95%CI 2.760-3.725, P=0.012) and three vessel disease (HR=2.008, 95%CI 1.549-3.372, P=0.040) were the independent predictors for 1-year mortality in patients of acute STEMI with primary PCI.
Conclusion: Non-IRA combining CTO in STEMI patients with primary PCI are usually having poor prognosis.

Objective To establish the pathogenic gene loci on 8q23.3-24.1 and 10p15 in this benigh adult familial myoclonic epilepsy (BAFME) pedigree.Methods After obtaining informed consent, peripheral blood samples were obtained from 7 BAFME patients and 13 control individuals;amplified polymerase chain reaction (PCR) and short tandem repeat (STR) method were employed to conduct linkage analysis;five STRs on chromosomal segments 8q23.3-q24.1 and three STRs on chromosomal segments 10p1 5 were chosen at genetic distances appropriate.Results Negative signal was all obtained for 8q23.3-q24.1 and 10p15 (LOD scores less than-2 for these STRs, respectively;θ=0.0), excluding involvement of these regions in the BAFME pedigree analyzed.Conclusion STR linkage analysis of 8q23.3-q24.1 and 10p 15 does not support linkage to these regions, indicating that the pathogenic gene in the pedigree we studied is not in these chromosome segments.
