Metabolic dysfunction-associated fatty liver disease （MAFLD） is a chronic metabolic liver disorder with complex etiologies. Different clinical phenotypes of MAFLD （such as obesity， hyperlipidemia， type 2 diabetes mellitus， the postmenopausal state， and chronic hepatitis B） have different mechanisms of action in the development and progression of MAFLD， leading to high heterogeneity in its clinical progression and prognosis. This article systematically reviews the pathogeneses and clinical features of the above five clinical phenotypes of MAFLD and elaborates on the corresponding individualized diagnosis and treatment regimens integrating traditional Chinese medicine and Western medicine， in order to provide a reference for clinical practice and improve clinical diagnosis and treatment.

Liver fibrosis is the core pathological stage of the progression of various chronic liver diseases to liver cirrhosis， and hepatic stellate cell （HSC） activation and the abnormal accumulation of collagen fibers are important processes for the development and progression of liver fibrosis. In recent years， studies have shown that HSC activation is regulated by the complex interactions between various organelles （including mitochondria， endoplasmic reticulum， Golgi apparatus， lysosome， and peroxisomes）， and such interactions affect the key cellular processes such as energy metabolism， protein synthesis and folding， reactive oxygen species balance， and autophagy， thereby participating in the progression of liver fibrosis. Meanwhile， traditional Chinese medicine and its active ingredients with multi-target synergistic effects have attracted wide attention. From the perspective of the interaction between organelles， this article systematically elaborates on the specific mechanism of such interactions in the progression of liver fibrosis and reviews how traditional Chinese medicine inhibits HSC activation and collagen production by regulating the function of these organelle and their interaction networks， thereby exerting an anti-liver fibrosis effect， in order to provide a theoretical basis for in-depth understanding of the pathological mechanism of liver fibrosis and the development of new traditional Chinese medicine intervention strategies.

OBJECTIVE To focus on the classic NOD-like receptor protein 3 （NLRP3）/Caspase-1/gasdermin D （GSDMD） pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula （HQHF） inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis （MASH）. METHODS RAW264.7 cells were divided into 5 groups： Control group （10% blank serum）， Model group [10% blank serum+5 μg/mL lipopolysaccharide （LPS）]， HQHF-L group （2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS）， HQHF-M group （5% drug-containing serum+5% blank serum+5 μg/mL LPS）， and HQHF-H group （10% drug-containing serum+5 μg/mL LPS）. After 24 h of routine culture post-administration， cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy； localization and expression of gasdermin D-N （GSDMD-N） were observed by immunofluorescence. Interleukin-1β （IL-1β） and IL-18 contents in supernatants were detected by ELISA； mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group， the Model group showed typical pyroptotic morphology （cell membrane bulging and pore formation）， increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane （ P ＜0.05）， significantly increased the contents of IL-1β and IL-18 in cell supernatants （ P ＜0.05）， and significantly up-regulated mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD in cells （ P ＜0.05）. Compared with the Model group， the HQHF-L， HQHF-M and HQHF-H groups showed improved pyroptotic morphology， reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N （ P ＜0.05）， significantly decreased the contents of IL-1β and IL-18 in cell supernatants （ P ＜0.05）， and significantly down-regulated mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD in cells （ P ＜0.05）. CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis， and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

Metabolic associated fatty liver disease （MAFLD） is a chronic liver disease with a rapidly increasing incidence rate worldwide， and its complex pathogenesis is closely associated with O-linked β-N-acetylglucosamine （O-GlcNAc） modification. As a dynamic and reversible post-translational modification of proteins， O-GlcNAc modification is mainly regulated by O-GlcNAc transferase and O-GlcNAcase. O-GlcNAc modification can drive hepatic steatosis， exacerbate insulin resistance， and impair mitochondrial function， thereby leading to the aggravation of metabolic disorders， promoting inflammation response， and driving the progression of MAFLD to metabolic associated steatohepatitis and hepatic fibrosis. This article systematically reviews the latest research advances in the role of O-GlcNAc modification in the development and progression of MAFLD， in order to provide theoretical support and research direction for a deeper understanding of the pathological mechanism of MAFLD and the development of effective therapeutic strategies.

Nonalcoholic fatty liver disease（NAFLD） is the most common chronic liver disease in the world. Because of its complex pathogenesis， high clinical prevalence and large population， it poses a great threat and challenge to public health in the world. Therefore， active intervention measures are needed. Currently， western medicine is effective in reducing weight， reducing liver fat content， improving glucose-lipid metabolism and insulin resistance. However， for patients with NAFLD-related fibrosis and cirrhosis， there is still a lack of sufficient histological evidence to support its benefits， and randomized controlled trials are still needed to clarify. Lifestyle intervention is an important cornerstone for the treatment of NAFLD， but there are many problems such as poor implementation and low compliance of patients， and the clinical efficacy is not ideal. Traditional Chinese medicine（TCM） has the significant advantages of multiple pathways and multiple targets. Berberine， the active ingredient of TCM， can interfere with the production of NAFLD from multiple pathways， including increasing energy consumption， weight loss， improving glucose-lipid metabolism， improving insulin resistance， anti-inflammatory， anti-oxidation， regulating intestinal flora， restoring bile acid homeostasis， anti-fibrosis and so on， which can play a positive role in the treatment of NAFLD. At the same time， it was found that the combination of BBR with Chinese and western medicines had significant advantages in promoting drug absorption， improving oral bioavailability， increasing the highest biological distribution in the liver， enhancing the overall therapeutic effect of NAFLD， and reducing adverse drug reactions， which could provide reference for clinical medication.

Objective:To investigate the efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.
