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.

ObjectiveTo systematically elucidate the accumulation characteristics of secondary metabolites in the stems and leaves of Panax ginseng with different stem colors. MethodsUltra-high-performance liquid chromatography-triple quadrupole-tandem mass spectrometry （UHPLC-QqQ-MS） was employed to determine the of 22 ginsenosides in the stems and leaves of 2- to 5-year-old P. ginseng plants with green and purple stems. Principal component analysis （PCA）， orthogonal partial least squares-discriminant analysis （OPLS-DA）， and one-way analysis of variance （ANOVA） were performed to explore the distribution patterns of ginsenosides from three dimensions： tissue distribution， growth duration， and stem color. Results① Tissue distribution： Leaves served as the primary organ for ginsenoside accumulation， exhibiting significantly higher total ginsenoside content than stems， which indicated distinct tissue-specific distribution of ginsenosides. ② Growth duration： Ginsenoside levels in stems generally peaked in the 2-year-old plants before stabilizing， while those in leaves displayed a declining-rebounding pattern， indicating that the 2-year-old plants （harvest stage） was a critical time point for the resurgence of leaf ginsenosides. ③ Stem color： A stage-specific correlation was observed between stem color and ginsenoside accumulation. In stems， the early-growth stage （2-year-old） of purple-stemmed plants exhibited higher content of specific ginsenosides （e.g.， ginsenoside Rk₁ and notoginsenoside R₁）， which may be associated with its stronger early-stage stress resistance. In leaves， the content of core ginsenosides （e.g.， ginsenosides Re and Rd） in 5-year-old plants with green stems showed a surpassing trend， demonstrating higher potential of resource development. ConclusionThe accumulation of ginsenosides in P. ginseng stems and leaves is multidimensionally regulated by tissue type， growth duration， and stem color phenotypes. Purple-stemmed plants exhibit early-stage specific ginsenoside accumulation and stress resistance potential， whereas green-stemmed plants are more advantageous for core leaf ginsenoside development at the harvest stage. The findings confirm that aboveground stem color can serve as a biomarker for directed breeding and efficient resource utilization of P. ginseng.

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.

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.

Objective To analyze the fluid resistance characteristics of different drafting formations in marathon swimming using computational fluid dynamics(CFD)method,and provide theoretical guidance for selecting optimal drafting strategies in competitions and training.Methods Multi-swimmer models were established via three-dimensional body scanning technology,and various formation models(I-,A-,V-,L-,H-type)were created by adjusting lateral and longitudinal distances between swimmers.The ANSYS Discovery Live software was used to simulate the overall resistance of different models and the resistance of individual swimmers within formations.Results The I3-type formation exhibited an overall drag reduction effect,reducing total resistance by 55.21％,whereas other formations increased overall resistance.The V-type formation showed the most significant resistance increase(31.88％).During drafting,the lowest resistance position was the rear position in the I3-type formation,while the highest resistance position was the middle position in the L-type formation.When leading,the fluid resistance of the leading swimmer in the A-type formation was significantly greater than that of an individual swimmer(P＜0.05).Conclusions Longitudinal drafting formations demonstrated superior drag reduction effects,with the rear position in a three-person longitudinal arrangement showing the optimal drag reduction.Considering both tactical considerations and drag reduction effects,swimmers are advised to avoid the middle position in lateral formations.

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.

BACKGROUND:Dental follicle cells are widely used in periodontal tissue regeneration engineering because of their excellent characteristics.With the development of biological scaffold materials,their relationship with periodontal tissue regeneration technology is increasingly close.OBJECTIVE:To review the performance of ivory follicle cells under the influence of internal and external biological factors by different experiments,and analyze their effects on the biological characteristics of dental follicle cells with scaffold materials.METHODS:Using"dental follicle cell,scaffolds,material,periodontal tissue regeneration,tissue engineering,review"as English and Chinese key words,the articles published in PubMed,Sciencedirect,and CNKI from 2013 to 2023 were searched,and finally 95 articles were included for analysis and discussion.RESULTS AND CONCLUSION:(1)Dental follicle cells originate from dental follicle tissue,which has certain stem cell differentiation potential.Because of its excellent performance,it is actively used in periodontal tissue regeneration engineering research.(2)The proliferation and osteogenic differentiation of dental follicle cells are affected by many biological factors,and both endogenous and exogenous factors can promote the proliferation and osteogenic differentiation of dental follicle cells to a certain extent.(3)3D printing technology and nanotechnology enable researchers to manufacture more suitable scaffold materials.(4)Polymer materials show us their flexibility and plasticity in periodontal tissue regeneration.We can manufacture targeted scaffold materials according to different defect sites to achieve efficient tissue regeneration.The good biocompatibility of inorganic materials makes them widely used in periodontal tissue regeneration engineering.By adjusting the content of nanoscale inorganic materials or improving the performance of scaffolds,scaffolds with better biocompatibility can be prepared.(5)There are many new synthetic(composite)materials,which show us excellent characteristics.However,because the mechanism of biological factors in scaffold materials on dental follicle cells is complicated,and the research on dental follicle cells is mostly concentrated on in vitro culture,so how to make scaffold materials more suitable for the growth and development of dental follicle cells and apply them safely and effectively in clinical treatment is the future research direction.

To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.
