With the accelerating aging of the population, the proportion of elderly patients with lung cancer continues to rise, presenting multiple challenges to perioperative management. This paper systematically reviews the clinical characteristics of elderly lung cancer patients. Based on the comprehensive geriatric assessment, it proposes incorporating seven major geriatric syndromes—frailty, delirium, sarcopenia, cognitive impairment, malnutrition, dysphagia, and mood disorders—into the core evaluation system. By integrating multimorbidity management with complication prevention and control, an integrated "geriatric syndrome-multimorbidity-complication" perioperative management model is constructed. Furthermore, this paper outlines stratified intervention strategies for geriatric syndromes, a "five-step" workflow for comorbidity management, and a comprehensive intervention pathway for complications across the preoperative, intraoperative, and postoperative phases. Multidisciplinary team (MDT) collaboration serves as the core mechanism to achieve individualized comprehensive treatment. This paper aims to provide a novel perioperative comprehensive treatment model for elderly lung cancer patients, which is centered on geriatrics, supported by multidisciplinary collaboration, and guided by precision medicine.

Guidelines, consensuses and standards play a significant role in guiding clinical diagnosis and treatment practices, optimizing the allocation of medical resources and reducing medical costs. To fully leverage the pivotal role of the National Clinical Research Center as a bridge between research evidence, recommendations of guidelines, consensuses and standards, and clinical practice, it is particularly urgent to construct a set of appropriate and efficient management system for guidelines, consensuses and standards. The National Clinical Research Center for Geriatric of West China Hospital, Sichuan University (hereinafter referred to as the center) has set the overall goal of " transparency, standardization, coordination, linkage and innovation leadership" and three phased goals of " achieving scientific, transparent and applicable management" " improving the multi-level, multi-subject coordination and linkage mechanism" and " promoting the homogenization of diagnosis and treatment services, process guarantee and standardized management" to explore the establishment of a management system for guidelines, consensuses and standards. Under this framework, the center has established the management committee and office for guidelines, consensuses and standards; build a dual-channel funding support model of " out-of-hospital+ in-hospital", established differentiated implementation models and formulated standardized processes; respectively formed clinical expert groups, methodology expert groups and evidence synthesis working groups, and carried out personnel training; and constructed a support platform for formulation, evaluation and promotion. As of October 2024, relying on the established management system for guidelines, consensuses and standards, the center has achieved a series of results in three aspects: formulating international evidence-based clinical practice guidelines, establishing a system of guidelines, consensuses and standards for geriatric disability, and building a standard system for medical and nursing integration, which has strongly supported clinical practice and the improvement of people′s livelihood by the government, and preliminarily completed the construction goals of the first phase, and can provide references for medical institutions committed to building a management system for guidelines, consensuses and standards.

Objective To develop an automated system that can accurately determine the relationship between the mandibular third molar and the mandibular nerve canal from panoramic images.Methods A dataset consisting of 600 panoramic images of the oral cavi-ty was selected,and the positions of the mandibular third molar and the mandibular nerve canal were accurately labeled.We compared the research designed TI-YOLOv5 with PANet,Faster R-CNN,Mask R-CNN,ResNeSt-101,and the original YOLOv5 in image seg-mentation tasks,with evaluation metrics of AP and AP50.Results TI-YOLOv5 achieved AP(average precision)54.0％and AP5094.9％,an increase of 4.9 and 6.7 percentage points respectively compared to the original YOLOv5(AP 49.1％,AP50 88.2％),and surpassed other SOTA methods such as Mask R-CNN(AP 45.1％,AP50 84.2％).Conclusion TI-YOLOv5 is significantly superior to mainstream networks in automatic positioning and relationship classification of mandibular wisdom teeth and neural tubes,with high de-tection accuracy and discrimination accuracy,and can provide reliable technical support for preoperative risk assessment of mandibular wisdom tooth extraction.

BACKGROUND:At present,the treatment of infected bone defects has the problems of long course of disease,poor treatment effect and high cost.The osteogenic effect of personalized bone replacement materials in clinical treatment is limited.Therefore,a 3D-printed bone graft material with both good osteogenic effect and antibacterial effect is urgently needed for clinical treatment. OBJECTIVE:To summarize the research status of 3D-printed scaffolds loaded with antimicrobial agents for the treatment of infected bone defects. METHODS:PubMed,Web of Science,Elsevier,and CNKI databases from January 2010 to June 2022 were searched for related articles.The Chinese search terms were"bone defect,3D printing,scaffold material,antibacterial,animal experiments,in vitro experiments".English search terms were"bone defect,3D printing,scaffold,antibiosis,animal experiment,in vitro".Finally,60 articles were included for review and analysis. RESULTS AND CONCLUSION:The 3D scaffolds made of titanium,magnesium,tantalum and other metals and their alloys have certain osteogenic properties,but do not have antibacterial function.Hydroxyapatite and other bioceramic materials have good biocompatibility and are prone to be degraded,whereas due to the lack of strength,they are usually combined with artificial polymer materials to form composite materials,which respectively mimic the inorganic and organic components in natural bone,and play their respective excellent functions.Antibiotics,silver/copper nanoparticles,antimicrobial peptides,gallium and other antibacterial agents play an antibacterial role by destroying bacterial cell membrane,producing reactive oxygen species to interfere with bacterial DNA replication,inhibiting iron absorption and other mechanisms.As a result,the 3D-printed scaffold has both antibacterial and osteogenic effects.However,there are still some problems such as drug resistance and difficult to control effective concentrations.3D-printed scaffolds are often loaded with antibacterial agents by loading drug-loaded microspheres on scaffolds,preparing antibacterial coating on the scaffold surface,and participating in joint 3D printing with drugs.The loading mode of antibacterial coating prepared on the scaffold surface is the most widely used,and its antibacterial effect is more stable.Nonetheless,the selection of the most suitable loading mode for antibacterial agents needs to be further discussed and summarized.It is a future research prospect to optimize the mechanical properties of composite scaffolds and prepare biomimetic bone scaffolds so that the degradation rate is consistent with the bone reconstruction rate in infected bone defects.The ideal antibacterial agents may play a role through a variety of antibacterial mechanisms,thus being expected to play a good antibacterial effect through low antibacterial concentration,which should be a hot spot of anti-bone infection research.After loading antibacterial agents on the surface of the scaffold,antibacterial agents can"intelligently"react to the local microenvironment,achieving controlled release,and regulating the osteogenesis,vascularization and immune response of the microenvironment,which is the focus of current research.

Objective:The study aimed to assess the scientific rigor, transparency, and practicality of Chinese geriatric medicine guidelines and consensus published in academic journals.Methods:A systematic search was conducted across 8 major Chinese and English databases to identify guidelines and consensus documents from Chinese scholars in 2022.Results:The selected documents were evaluated using the STAR rating tool, resulting in the inclusion of 2 guidelines and 19 expert consensuses.The total scores ranged from 9.0 to 50.6 points, with an average score of 29.6±13.1 points.The highest score rate in the'Consensus Methods’category of expert consensuses was 47.4%, while the lowest score rate in the'Registration’category was 0.For guidelines, the highest score rate in the'Consensus Methods’category was 42.9%, while the lowest score rates were observed in the'Registration’, 'Plan’, and'Others’categories at 0.Conclusions:The overall quality of geriatric medicine guidelines and consensus in China requires enhancement.There is a need to improve training in guideline consensus development, involve methodologists, elevate the standards for journal publication, and strive to enhance the scientific rigor, transparency, and practicality of guidelines and consensus documents.

Open fund projects play an important role in strengthening discipline construction and enhancing research capabilities. The National Clinical Research Center for Geriatrics of West China Hospital, Sichuan University (hereinafter referred to as the Center) initiated the establishment of open fund projects in 2018. However, due to their strong disciplinary and autonomous nature, as well as the presence of uncertainty, these projects posed new challenges to project management. Therefore, based on the theory of project integration management, the Center has established an integrated management system for open fund projects. This system was achieved by identifying the construction objectives of open fund projects, defining their scope of application, and integrating the four essential elements of project management: execution, processes, control, and support. It ensured standardized execution through organizational and institutional measures, optimized management processes, implemented control through the development of milestone lists, risk registration lists, superior funding lists, and non-performing lists, and integrated technology and platforms as support. The system was implemented since 2020, realizing comprehensive and holistic management of open fund projects across all stages and elements, thereby effectively enhancing management efficiency and quality. As of December 2023, 112 open fund projects have been approved, with a total funding of 31.943 million yuan. These projects have yielded a series of achievements in cohort study and platform construction, academic output, and have demonstrated remarkable effectiveness in projects and talents cultivation. The construction and application of this system can provide reference for medical institutions in managing open fund projects.
