ObjectiveTo investigate the therapeutic effects and mechanisms of Qinlian Hongqutang （QLHQT） on nonalcoholic steatohepatitis （NASH）. MethodsC57BL/6J mice were randomly divided into normal and modeling groups. The NASH model was established by feeding a high-fat diet for 12 weeks. After successful modeling， mice were randomly assigned to the model group， low-， medium-， and high-dose QLHQT groups （0.51， 1.02， and 2.04 g·kg^-1）， and a positive control metformin group， with six mice in each group. The mice were treated for 8 weeks. Body weight was recorded before and after treatment. Serum levels of total cholesterol （TC）， triglycerides （TG）， and low-density lipoprotein cholesterol （LDL-C）， as well as hepatic TC， TG， and LDL-C contents， were determined by biochemical assays. Hematoxylin-eosin （HE） staining and oil red O staining were used to evaluate liver histopathology and lipid deposition， respectively. Flow cytometry， enzyme-linked immunosorbent assay （ELISA）， and Real-time polymerase chain reaction （Real-time PCR） were used to assess hepatic macrophage expression and related markers. Western blot and immunofluorescence were used to investigate the potential mechanisms of QLHQT in regulating macrophage polarization. ResultsCompared with the normal group， body weight and serum and hepatic levels of TC， TG， and LDL-C were significantly increased in the model group （P<0.01）. Liver histopathology showed unevenly distributed round lipid droplets in the hepatocyte cytoplasm， accompanied by inflammatory cell aggregation. Flow cytometry showed that the proportion of CD86-positive cells was significantly increased， whereas the proportion of CD206-positive cells was markedly decreased （P<0.05）. Hepatic inducible nitric oxide synthase （iNOS） levels and tumor necrosis factor-α （TNF-α） mRNA expression were significantly increased， while hepatic IL-10 levels and IL-4 mRNA expression were significantly decreased （P<0.01）. The protein expression levels of Toll-like receptor 4 （TLR4）， tumor necrosis factor receptor-associated factor 6 （TRAF6）， and myeloid differentiation factor 88 （MyD88） in the liver were significantly increased （P<0.01）. Compared with the model group， body weight was reduced in the high-， medium-， and low-dose QLHQT groups and in the metformin group. Serum and hepatic TC， TG， and LDL-C levels were significantly decreased （P<0.01）. Liver histopathology showed alleviated hepatic lipid deposition， with markedly reduced lipid droplets and inflammation. Immunofluorescence and flow cytometry showed that the proportions of CD86-positive cells were significantly decreased， whereas the proportions of CD206-positive cells were significantly increased in the high-， medium-， and low-dose QLHQT groups （P<0.05）. Hepatic iNOS levels and TNF-α mRNA expression were significantly decreased （P<0.01）， whereas hepatic IL-10 levels and IL-4 mRNA expression were significantly increased （P<0.01）. The hepatic protein expression levels of TLR4， TRAF6， and MyD88 were significantly decreased， while signal transducer and activator of transcription 6 （STAT6） phosphorylation was significantly increased （P<0.05， P<0.01）. There was no statistically significant difference in total STAT6 protein expression. ConclusionQLHQT effectively ameliorates hepatic inflammation in NASH mice， and the mechanism may involve STAT6- and TLR4-mediated signaling pathways driving polarization of M1 macrophages toward the M2 phenotype.

Natural flavonoids have attracted considerable attention owing to their favorable biosafety profiles and multiple pharmacological properties in recent years. Luteolin, a representative flavonoid compound, exhibits anti-inflammatory, antioxidant, anti-angiogenic, and neuroprotective effects in multiple ocular disease models by modulating key signaling pathways, including NF-κB, PI3K/Akt, Nrf2/HO-1, and AGE-RAGE. Accumulating experimental evidence supports the potential application of luteolin in various ocular diseases, including corneal and ocular surface diseases, inflammatory eye diseases, glaucoma, cataract, diabetic retinopathy, and age-related macular degeneration. However, clinical evidence remains limited. This review systematically summarizes research progress on luteolin in ocular diseases over the past five years, analyzes its molecular mechanisms and therapeutic potential, and discusses future directions,so as toprovide a theoretical basis for clinical translation.

Objective:To develop an exercise rehabilitation program based on the Temporal Self-regulation Theory and evaluate its effectiveness in elderly patients with hip fractures.Methods:A total of 84 elderly patients with hip fractures admitted to the Department of Trauma Orthopedics at the First Affiliated Hospital of University of South China from May to August 2024 were enrolled using convenience sampling. Participants were randomly assigned to an experimental group ( n=42) and a control group ( n=42) using a random number table. The control group received routine exercise rehabilitation, while the experimental group received an exercise rehabilitation program constructed based on the Temporal Self-regulation Theory. The program included components such as establishing a unified concept of "exercise-rehabilitation", enhancing time-limited efficacy, achieving behavioral advantages, and improving self-regulation of active movement. Both groups received interventions for 12 weeks. Functional exercise adherence, activities of daily living, and hip joint function were assessed using the Orthopedic Exercise Adherence Scale, Modified Barthel Index, and Harris Hip Score at four time points: before intervention, on the day of discharge, and at 4 and 12 weeks postoperatively. Results:During the study, two patients from each group dropped out. Results of the generalized estimating equations showed group effects, time effects, and interaction effects in adherence scores with statistically significant differences ( P<0.01). On the day of discharge, and at 4 and 12 weeks postoperatively, the adherence scores in the experimental group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05). Repeated measures ANOVA indicated that group effects, time effects, and interaction effects were also statistically significant in scores for daily living ability and hip joint function ( P<0.05). The experimental group scored higher than the control group at each time point with statistically significant differences ( P<0.05) . Conclusions:The exercise rehabilitation program based on the Temporal Self-regulation Theory is scientifically sound and practical. It can effectively improve functional exercise adherence, enhance daily living ability, and promote postoperative recovery of hip joint function in elderly patients with hip fractures.
