Chronic obstructive pulmonary disease （COPD）， as one of the three major causes of death， is a complex systemic disease with high prevalence， high mortality， high disability， frequent acute exacerbations， and a variety of pulmonary complications. The pathogenesis is complex. Western medicine has no effective specificity scheme for a complete cure. However， multiple-component and multiple-target characteristics of traditional Chinese medicine （TCM） demonstrate significant advantages in COPD treatment through multi-link， multi-pathway， and multi-mechanism intervention. Therefore， exploring the essence of COPD pathogenesis and discovering effective TCM treatment drugs through the application of TCM principles and prescriptions is a key focus of modern research. Animal models are of paramount importance in medical research. It is the first consideration to select appropriate animals， adopt reasonable modeling methods to replicate stable animal models that closely resemble the clinical manifestations and pathophysiological characteristics of COPD， and use appropriate evaluation methods to determine the success of COPD animal models in experimental research. The core of experimental research lies in observing the intervention effect of TCM on COPD animal models， exploring the specific pathways and regulatory mechanisms of TCM on COPD disease， and finding TCM monomers， single herbs， and TCM formulas with definite curative effects. At present， animal model research on COPD mainly involves model establishment， model evaluation， efficacy observation， mechanism exploration， and other aspects. In recent years， there has been no systematic organization， update， and reflection on the relevant research on TCM intervention in COPD animal models. This study reviewed the selection of animals for the COPD model， methods for establishing COPD animal models， model evaluation methods， and the intervention effects of TCM on COPD animal models. It aims to grasp the current research status and identify existing problems for further improvement， in order to provide evidence and support for scientific research and clinical treatment of COPD.

Objective To observe the ultrasonic manifestations of aggressive angiomyxoma(AAM).Methods Four patients with newly diagnosed AAM and 3 with recurrent AAM confirmed by pathology were retrospectively enrolled,and the ultrasonic manifestations were analyzed.Results Among 7 cases of AAM,the lesions located in subcutaneous regions of perineum in 3 cases,in both perineum and pelvic cavity in 2 cases,in pelvic cavity and in cervix each 1 case,with a median maximum diameter of 7.6 cm.The lesions mainly manifested as heterogeneous hypoechoic,scattered cord-like moderate/moderate-hyperechoic inside,regular or lobulated shape with finger-like protrusions,with clear boundary or unclear boundary with adjacent vagina/rectum.Layered structure could be observed with gray-scale ultrasound and CDFI.Conclusion AAM mainly affected pelvis and perineal region,often manifested as large lesion tended to infiltrate surrounding areas and form finger-like protrusions,most with clear boundaries and interior heterogeneous hypoechoic regions,also the characteristic stratified structures.

Chronic obstructive pulmonary disease （COPD）， as a chronic respiratory disease that can be prevented and intervened but cannot be completely cured， has increasing incidence and mortality rates year by year， often complicated by one or more comorbidities. However， there is currently no specific treatment available. Therefore， the healthcare issues related to COPD are urgent and prominent. Traditional Chinese medicine （TCM） delays the progression of COPD through multiple mechanisms， pathways， and targets. As a result， exploring the pathogenesis of COPD and identifying TCM treatment approaches and effective prescriptions are key issues that urgently need to be addressed in clinical practice. In TCM， COPD is categorized into syndromes such as "cough"， "asthma"， and "lung distension". It is believed that the deficiency in the origin runs through the entire disease. When external pathogens invade， Qi becomes disordered， and phlegm and blood stasis begin to accumulate， leading to an excess condition in the manifestation. Modern medicine research on the pathogenesis of COPD mainly involves aspects such as inflammatory response， oxidative stress， autophagy imbalance， and aging. Studies have found that Chinese medicine monomers， single herbs， and compound prescriptions can improve COPD by inhibiting inflammation， reducing oxidative damage， correcting autophagy， and delaying aging. However， there is no study that intuitively organizes the various pathogenesis mechanisms of COPD and their interrelationships. At the same time， research on the therapeutic effects of TCM on COPD primarily focuses on exploring a single mechanism or pathway， without integrating multiple mechanisms， pathways， and targets. Additionally， there are very few studies that summarize the corresponding relationships between the various pathogenesis mechanisms of COPD and the regulatory effects and signaling pathways of Chinese medicine. This study， for the first time， combines the latest literature in China and abroad to explain the various pathogenesis mechanisms of COPD and their interrelationships using a combination of graphs， text， and tables. It also outlines the signaling pathways， targets， and mechanisms of Chinese medicine monomers， single herbs， and compound prescriptions in regulating COPD， in order to provide new ideas and strategies for the in-depth research and systematic treatment of COPD with TCM.

Idiopathic pulmonary fibrosis(IPF)is a chronic progressive disease with a short survival time after diagnosis.Current treatments using western medicines have shown poor efficacy and lung transplantation is costly,highlighting the need to find new,safe,and effective treatments.Animal experiments are important for investigating the mechanisms of drug action,and suitable animal models of IPF are required for experimental research.Bleomycin is commonly used to induce IPF models.Traditional Chinese medicine(TCM)has the advantages of multiple therapeutic targets and few adverse reactions,and is gradually gaining attention for the treatment of IPF.Ongoing experimental research is being carried out to verify the specific targets and mechanisms of TCM in the treatment of IPF,utilizing animal models of IPF.This review considers the selection of animal models of IPF,the method used to induce,establish,and evaluate the models,and the interventional effects of TCM.We also summarize the best modeling method for animal models of IPF and the current status of TCM treatments to provide a basis for further scientific research and the clinical treatment of IPF.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To explore the value of ultrasound imaging characteristics combined with clinical indicators in assessing the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC).Methods:A retrospective analysis was conducted for patients who underwent pancreatic contrast-enhanced ultrasound (CEUS) from September 2017 to October 2023 at Peking Union Medical College Hospital and were diagnosed with PDAC based on pathological findings. Various parameters were recorded, including CA19-9 levels, tumor size, location, morphologic features, echogenicity, presence of internal cystic components, dilatation of the main pancreatic duct, peripheral vascular invasion, CEUS characteristics, presence or absence of liver metastasis, and treatment methods. In April 2024, patient survival information was obtained through telephone follow-up or review of medical records. Based on the results of the cox regression model analysis, a nomogram model of the risk of death was developed. The receiver operating characteristic (ROC) curves were applied to evaluate the predictive efficacy of the model. The calibration curves were plotted to evaluate the accuracy of the model, and clinical decision curves were used to evaluate the clinical benefit of the model.Results:This study included a total of 207 patients with PDAC. As of April 2024, 71 patients were alive and 136 died, with a median survival time of 14 months (95% CI: 12 -17). Multivariate analysis confirmed that the elevated CA19-9 ( HR=1.689, 95% CI: 1.102-2.588), tumor size >4 cm ( HR=1.641, 95% CI: 1.159-2.322), taller-than-wide shapes ( HR=1.450, 95% CI: 1.019-2.065), incomplete hypo-enhancement ( HR=1.618, 95% CI: 1.100-2.380), and liver metastasis ( HR=1.687, 95% CI: 1.175-2.423) were independent risk factors for survival in patients with PDAC. A nomogram model was further constructed for 6-month, 12-month and 3-year survival of patients with PDAC. The areas under the ROC curve were 0.679, 0.705 and 0.815, respectively. The calibration curves suggested that the model was more accurate, and the clinical decision curves showed that the model had a better clinical benefit. Conclusion:The combined use of ultrasound imaging characteristics and clinical indicators could effectively predict the prognosis of PDAC patients. Specifically, tumor size >4 cm, taller-than-wide shapes, incomplete hypo-enhancement, elevated CA19-9, and the presence of liver metastasis are correlated with poorer survival outcomes. The nomogram model constructed on the basis of these factors can be used to assess the survival of patients with PDAC.

Erdheim-Chester disease（ECD）is a rare multisystem disorder characterized by the infiltration of tissues by foamy CD68 +CD1a - histiocytes. The role of multiple imaging modalities in the management of ECD is complementary. As ultrasound represents a screening tool in clinical practice，sonographers need to heighten the awareness of ECD. Early recognition through ultrasound may facilitate timely diagnosis for this complex systemic condition. This article reviewed the application of ultrasound in the diagnosis and treatment of ECD.
