Metabolic dysfunction-associated fatty liver disease （MAFLD） is the most prevalent chronic liver disease worldwide， with a complex pathogenesis. Mitochondria play a pivotal role in this disease process， and studies have confirmed that mitochondrial dysfunction can exacerbate metabolic disorders and induce innate immune imbalance， while mitochondrial DNA （mtDNA） is the core molecule mediating these two pathological effects. After the abnormal release of mtDNA， it can be recognized by intracellular pattern recognition receptors， which in turn triggers innate immune responses and causes tissue damage， forming a pathological pathway of “mtDNA release-immune activation-tissue damage”. Currently， there is a lack of systematic reviews summarizing the mechanism of action of this pathway in different stages of MAFLD and the intervention strategies targeting this pathway. This article systematically reviews the core molecular mechanism of this pathway， its pathological role in the development and progression of MAFLD， and the current intervention strategies targeting this mechanism， in order to provide a theoretical basis for analyzing the pathogenesis of MAFLD and developing novel therapeutic strategies.

Immunogenic cell death(ICD)is a form of cell death that can activate the immune system,especially in the treatment of cancer.ICD can enhance the recognition of tumors by the immune system and the release of damage associated molecular patterns(DAMPs),to achieve tumor cell death.Oncolytic viruses(OVs)can selectively infect and kill tumor cells without damaging normal cells.OVs are type Ⅱ ICD inducers that induce ICD in tumor cells by targeting the endoplasmic reticulum.Here,we review the characteristics of ICD and the mechanism of ICD induction by OVs.We also review the latest clinical progress involving ICD and discuss future treatment strategies for tumors.

Objective To investigate the effect of baseline atherogenic index of plasma(AIP)on the long-term prognosis of patients with acute myocardial infarction(AMI).Methods A total of 712 AMI patients admitted to the hospital from January 2018 to December 2019 were continuously included as subjects and divided into a low-value group(AIP<0.280,n=237),a median-value group(AIP 0.280～0.852,n=238)and a high-value group(AIP>0.852,n=237)according to the baseline AIP tertiles.The primary endpoint was defined as the occurrence of major cardiovascular adverse events(MACEs).Multivariate Cox regression was used to analyze the independent influencing factors of MACEs.The nonlinear relationship between AIP and the risk of MACEs was analyzed with restricted cubic spline plots.Kaplan-Meier curve was used to analyze survival differences between groups.Subgroup analysis assesses the consistency of AIP's predictive value to MACEs.Results With the increase of AIP tertile groups,the proportion of dyslipidemia and MACEs increased,white blood cell count,fasting blood glucose,triglyceride,total cholesterol,low density lipoprotein and AIP increased,and high-density lipoprotein decreased,with statistical significance(P<0.05).Multivariate Cox regression analysis showed that AIP was an independent risk factor for MACEs(HR=2.024,95%CI:1.211～3.381,P=0.007).The results of restricted cubic spline analysis show that there is an L-shaped nonlinear effect relationship between AIP and the risk of MACEs(P-nonlinear=0.008).When AIP>0.613,the risk of MACEs in AMI patients increases with the increase of AIP.Kaplan-Meier survival curve analysis results show:With the increase of AIP,the cumulative incidence of MACEs in AMI patients increased significantly(Log-rank test,P=0.032).Compared with the low-value group,the risk of MACEs in the high-value group increased by 131%(HR=2.311,95%CI:1.261～4.234,P=0.007).The results of subgroup analysis showed that the P value of interaction within each subgroup was not significant,and the ability of AIP to predict MACEs was applicable to all subgroups.Conclusion Increased AIP at baseline is an independent predictor of poor long-term prognosis in patients with AMI.

Establishing a one-stop diagnosis and treatment mode centered on patients and linked by diseases is of great significance for optimizing the medical process and improving the medical experience. In March 2024, a tertiary hospital integrated pediatric outpatient and emergency resources, established a pediatric diagnosis and treatment island through reasonable department settings, strengthened talent team construction, optimized diagnosis and treatment processes, and established supporting guarantee mechanisms. It was officially put into use in June of the same year, providing one-stop diagnosis and treatment services for children and achieving the goal of " not leaving the island for minor illnesses and not leaving the hospital for major illnesses". Before the operation of island (January May 2024), the complaint rate and waiting time for pediatric outpatient and emergency department were 39 cases per 100 000 patients and 15 to 30 minutes, respectively; After operation (June August 2024), the complaint rate and waiting time decreased to 17 cases per 100 000 people and 10 to 20 minutes respectively; The average monthly comprehensive income of outpatient and emergency departments increased by 33%. The pediatric diagnosis and treatment island mode could assist in the sustainable high-quality development of pediatrics in hospital, and provide references for optimizing outpatient and emergency department management in other tertiary public hospitals. In the future, we should further enrich the service content of the island and strengthen information technology construction.

Transmissible gastroenteritis(TGE)is a highly contagious gastrointestinal disease of pigs caused by the transmissible gastroenteritis virus(TGEV).It results in severe diarrhea and high mortality in suckling piglets.As no specific treatment available,vaccination is considered to be one of the most cost-effective measures for preventing and controlling TGE.However,the immune protection provided by vaccines based on traditional TGEV strains is becoming inadequate due to the continuous emergence of strong and new strains of the virus,which poses a serious threat to the pig industry's health and development.Therefore,the development of new vaccines with im-proved efficiency and broad-spectrum coverage is urgently needed.This paper aims to summarize the pathogenic structural characteristics of TGEV,discuss the latest advancements in TGEV vac-cine research and development,and propose future strategies for the development of highly effec-tive TGEV vaccines.The findings of this paper can serve as a valuable reference for effectively pre-venting and controlling TGE in clinical practice.

Nonalcoholic steatohepatitis （NASH） is a chronic metabolic disease characterized by hepatocyte fatty degeneration and ballooning degeneration， and it plays an important role in the progression of hepatic steatosis. Recent studies have shown that immune homeostasis imbalance between T helper 17 （Th17） and regulatory T （Treg） cells are closely associated with the pathological process of NASH. Transforming growth factor-β1 （TGF-β1） is a key cytokine for regulating the differentiation and proliferation of Th17/Treg cells， and TGF-β1 binds to its receptor and activates the Smad signaling pathway， thereby regulating the immune balance of Th17/Treg cells and the expression of inflammatory factors and participating in the repair of liver inflammation. This article systematically reviews the molecular mechanism of the TGF-β1/Smad signaling pathway in affecting NASH by regulating the immune balance of Th17/Treg cells， in order to provide a theoretical basis for the research on the pathogenesis of NASH and related treatment strategies.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.
