BACKGROUND:Dysfunction of macrophage efferocytosis can induce local and systemic inflammatory damage and is associated with a variety of obesity-related metabolic diseases.Moreover,compounds targeting efferocytosis have shown good therapeutic effects. OBJECTIVE:By reviewing the effects of obesity on macrophage efferocytosis,to analyze the key mechanism by which obesity inhibits efferocytosis,to summarize the research progress in compounds targeting efferocytosis to treat obesity-related metabolic diseases,so as to provide new ideas for fully understanding efferocytosis and its relationship with metabolic diseases,aiming to provide new strategies for disease prevention and treatment. METHODS:The English search terms were"efferocytosis,metabolism,obesity,obese,atherosclerosis,non-alcoholic steatohepatitis,neurodegeneration,tumor,osteoarthritis,diabetes,compound,medicine,treatment,"which were used for literature retrieval in PubMed and Web of Science.The Chinese search term was"efferocytosis,"which was used for literature retrieval in CNKI,VIP and WanFang datebases.Ninety-nine papers were finally included in the review analysis after a rigorous screening process. RESULTS AND CONCLUSION:In the process of efferocytosis,the"Find me"and"Eat me"processes involving a large number of apoptotic cell derived factors are mainly regulated by apoptotic cells.The efferocytosis factor involved in cytoskeletal remodeling and digestion are mainly derived from macrophages,which are crucial for efferocytosis activity.These results suggest that the"Find me"and"Eat me"factors mainly reflect the condition of apoptosis,and it is more scientific to select the expression of factors involved in cytoskeletal remodeling and digestion when evaluating the efferocytosis activity of macrophages.Obesity inhibits efferocytosis,and shows an inhibitory effect on most digestive factors,but has a stress-induced activation effect on most"Find me,""Eat me"and cytoskeletal recombination factors,which further indicates the decisive effect of digestive stage on efferocytosis and suggests that it is not reliable for some studies to evaluate the efferocytosis based on the increased expression of"Find me"and"Eat me"factors.Targeting cytokines in the digestive phase may be more effective when discussing future intervention strategies targeting macrophages efferocytosis.The efferocytosis activators of macrophages are effective in the treatment of various metabolic diseases,but the efferocytosis inhibitors in tumor tissue show good anticancer effects,suggesting that the role of efferocytosis should be rationally evaluated according to the characteristics of tissue inflammation.Efferocytosis is a relatively new concept proposed in 2003,with a short research history and complex efferocytosis factors.Current studies on obesity and efferocytosis only involve a tip of the iceberg and most of them are at a superficial level and a large number of scientific experiments are needed to further validate the mechanisms.

Elderly end-of-life patients often experience distress due to being caught in dilemmas of contemplation and decision-making. Narrative wills， grounded in life values and premised on respecting individual wishes and needs， present an individual’s unique life story through narrative forms， conveying their overall experience， interpretation of meaning， and understanding of life. They are preserved and passed on in a way that meets individual expectations， thereby promoting human exploration， reflection， and growth regarding the meaning of life through interpersonal interactions that transcend space and time. This paper explored the concept of narrative wills among elderly end-of-life patients， the ethical value and ethical principles of narrative wills， and the moral and ethical risks. It also provided specific ethical interpretations， assisting in the application and development of narrative wills in elderly end-of-life patients.

ObjectiveTo analyze the influencing factors of pulmonary dysfunction among community-based population at high-risk for chronic obstructive pulmonary disease (COPD), and to establish a risk assessment model to provide a reference basis for accelerating the beforehand prevention and control of COPD and promoting the respiratory health of community-based residents. MethodsIndividuals aged >35 years old, with at least one risk factor except age illustrated in the Guidelines for Primary Diagnosis and Treatment of Chronic Obstructive Lung Disease (2018), and participated in the early screening for COPD from July 2022 to December 2023 were selected as the research subjects, and their lung function was assessed by the forceful expiratory volume in the first second after inhalation of bronchodilator (FEV₁)/ forced vital capacity (FVC) <70% and/or the ratio of FEV₁ to predicted value (FEV₁%Pred) <80% as the diagnostic criteria. In addition, risk factors related to pulmonary dysfunction were analyzed for the establishment of risk assessment model. ResultsA total of 823 individuals aged between 35‒76 years were included, among which 298 (36.21%) were diagnosed with pulmonary dysfunction, 167 (20.29%) with COPD, and 131 (15.92%) with preserved ratio but impaired spirometry. Logistic regression analysis revealed that male gender, increasing age, more frequent smoking, insufficient physical activity, recurrent wheezing, the presence of post-exercise wheezing or coughing, insensitive to airborne allergens, and history of chronic bronchitis or bronchial asthma were correlated with pulmonary dysfunction. The incidence rate of pulmonary dysfunction was 1.99 times higher in males than that in females, 1.81 times more common in those aged between 70‒76 years than those aged <60 years, 2.42 times more common in those who smoked 50‒200 pack-years than in those who smoked 0‒14 pack-years, 1.78 times higher in those who underwent physical activity <600 MET‑min·week^-1 than in those who underwent physical activity ≥600 MET‑min·week^-1, 2.61 times higher in those suffered recurrent wheezing than in those did not, 1.53 times higher in those with symptoms of post-exercise wheezing or coughing than in those without, 1.61 times higher in those insensitive to airborne allergens than those sensitive, 2.02 times higher in patients with chronic bronchitis than in those without, and 2.41 times higher in patients with bronchial asthma than in those without. The risk assessment model for pulmonary dysfunction constructed on this basis had a total score of 28 points, and the area under the subject operating characteristic (ROC) curve was 0.72, reaching the cut-off point of ROC curve while taking scores ≥10 points as the cut-off value for pulmonary dysfunction. ConclusionIn community-based high-risk COPD population, the incidence rate of pulmonary dysfunction is higher in males than that in females, in addition, which increases with the advancement of age. Smoking,insufficient physical activity,recurrent wheezing,post-exercise wheezing or coughing,insensitive to airborne allergens,and history of chronic bronchitis or bronchial asthma are high risk factors for pulmonary dysfunction. The risk assessment model constructed based on these factors has a good predictive effect in screening high-risk population of COPD, but its effectiveness in screening people at general risk needs to be further validated.

Objective To investigate the factors influencing international normalized ratio (INR)>3.0 in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Methods A retrospective analysis was performed on the clinical data of patients who underwent mechanical heart valve replacement surgery and received warfarin anticoagulation therapy at West China Hospital of Sichuan University from January 1, 2011 to June 30, 2022. Based on the discharge INR values, patients were divided into two groups: an INR≤3.0 group and an INR>3.0 group. The factors associated with INR>3.0 at the time of discharge were analyzed. Results A total of 8901 patients were enrolled, including 3409 males and 5492 females, with a median age of 49.3 (43.5, 55.6) years. The gender, body mass index (BMI), New York Heart Association (NYHA) cardiac function grading, INR, glutamic oxaloacetic transaminase, and preoperative prothrombin time (PT) were statistically different between the two groups (P<0.05). Multivariate logistic regression analysis revealed that lower BMI, preoperative PT>15 s, and mitral valve replacement were independent risk factors for INR>3.0 at discharge (P<0.05). Conclusion BMI, preoperative PT, and surgical site are factors influencing INR>3.0 at discharge in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Special attention should be given to patients with lower BMI, longer preoperative PT, and mitral valve replacement to avoid excessive anticoagulation therapy.

Objective:To investigate the pulmonary function in patients with Parkinson's disease(PD)and the association between pulmonary function and motor symptoms.Methods:A total of 104 PD patients were included in the study,and a portable spirometer was used to assess pulmonary function.According to the results of pulmonary function,the patients were divided into ventilation dys-function group with 37 patients and non-ventilation dysfunction with 67 patients,and clinical data were compared between the two groups.Univariate and multivariate logistic regression analyses were used to investigate the factors associated with abnormal pulmonary function,and a Spearman correlation analysis was used to investigate the correlation between pulmonary function parameters and motor symptoms.Results:There were significant differences in the scores of bradykinesia and postural gait between the two groups(P<0.05),and the logistic regression analysis showed a positive correlation between pulmonary ventilation dysfunction and postural gait score(regression coefficient β=0.171,95%CI=1.015-1.386,P=0.032).There were significant differences between the patients with different stages of PD in the pulmonary function parameters of the percentage of forced vital capacity in predicted value(t=2.143,P=0.034),the percentage of forced expiratory volume in 1 second(t=2.118,P=0.037),the percentage of predicted peak expiratory flow(t=2.002,P=0.048),maximum expiratory pressure as a percentage of predicted value(t=2.412,P=0.018),and maximum inspiratory pressure as a percentage of predicted value(t=2.119,P=0.036).Conclusion:The pulmonary function parameters of PD patients are lower than expected values,and the incidence rate of pulmonary ventilation dysfunction is 35.58%,with the main manifestation of restrictive ventilatory dysfunction.There is a correlation between pulmonary function and motor symptoms in PD patients.
