ObjectiveTo investigate the ameliorative effect of paeonol on acute alcohol-induced hepatic inflammation in mice via the regulation of the short-chain fatty acids (SCFAs)-specific receptor GPR43/mitogen-activated protein kinase (MAPK) signaling pathway. MethodsC57BL/6 mice were randomly divided into five groups: blank control group, model group, low-dose paeonol group (120 mg·kg-1), high-dose paeonol group (480 mg·kg-1), and silybin group (36.8 mg·kg-1). A mouse model of alcohol-induced liver disease (ALD) was established by ad libitum administration of a Lieber-DeCarli alcohol liquid diet. Serum lipid levels, liver function, inflammatory cytokines, and oxidative stress markers were measured. Liver hematoxylin-eosin (HE) staining and Oil Red O staining were performed to validate successful modeling. Western blot analysis was used to assess the expression levels of zonula occludens-1 (ZO-1), Claudin-1, and proteins related to the GPR43/MAPK signaling pathway in the colonic tissue. Immunohistochemistry was employed to detect the protein expression of GPR43, ZO-1, and Claudin-1 in the colon. Then 16S rDNA sequencing was performed to analyze differences in intestinal flora between the model group and the high-dose paeonol group. Additionally, fecal microbiota transplantation (FMT) experiments were conducted to validate the regulatory effect of paeonol on ALD via modulation of intestinal flora. ResultsCompared with the blank control group, the model group showed significantly elevated serum lipid levels, oxidative stress, and inflammatory cytokine expression (P<0.01). Liver histology revealed increased inflammatory infiltration and lipid droplet accumulation. Colonic mucosal injury and impaired intestinal barrier function were observed. Levels of MAPK pathway-related proteins in the colonic tissue were upregulated (P<0.01), while GPR43, ZO-1, and Claudin-1 protein expression levels were significantly decreased (P<0.01). The composition and abundance of the intestinal flora were markedly altered, with a reduced Bacteroidetes-to-Firmicutes ratio and decreased relative abundances of Eubacterium, Parabacteroides, Erysipelothrix, and Adlercreutzia, alongside increased abundances of Clostridium butyricum, Enterococcus, and Helicobacter pylori in the model group. Compared with the model group, paeonol significantly reduced serum lipid levels, oxidative stress responses, and the expression of inflammatory cytokines in ALD mice (P<0.05, P<0.01). It also attenuated hepatic lipid accumulation, restored intestinal barrier function, and repaired the structural integrity of liver and colonic tissues. The protein expression levels of ZO-1, Claudin-1, and GPR43 in the colonic tissue were significantly increased (P<0.05, P<0.01), while those of MAPK pathway-related proteins were significantly decreased (P<0.05, P<0.01). The intestinal flora dysbiosis was effectively alleviated, rendering its composition closer to that of normal mice. The efficacy of paeonol in modulating ALD was further confirmed by FMT experiments, supporting its mechanistic involvement in the SCFAs-GPR43/MAPK signaling pathway. ConclusionPaeonol exerts a protective effect against ALD in mice, which may be mediated through regulation of the SCFAs-GPR43/MAPK signaling pathway, thereby achieving anti-inflammatory effects and improving intestinal barrier function.

Since 1986, the WHO has held ten global health promotion conferences covering various health promotion issues and sustainable development worldwide. These sessions have formed a series of consensus and actions that guide promoting health globally. This study analyzed the declarations, reports, and news materials from the ten conferences that studied health promotion action areas, focal topics, actor networks, partnership relationships, and other significant outcomes. It also explored how these conferences contributed to the construction and advancement of global health promotion consensus and actions. The first Global Conference on Health Promotion identified the concept of health promotion and five key action areas, laying the foundation for subsequent conferences and health promotion actions. Over the years, the ten conferences continuously expanded the essence of health promotion, developed partnership relationships, formulated public health promotion policies, and called for health promotion actions. This process culminated in the formation of global consensus and collective actions. The latter conferences have gained significant attention and influence. The conferences offer valuable insights for future global health promotion endeavors and provide global perspectives and pathways for the development of Healthy China.

Radiotherapy is one of the main treatment methods for malignant tumors, which can cause the radiation damage to normal tissues. Radiation-induced skin injury (RISI) is one of the main adverse reactions caused by radiotherapy. The main clinical manifestations of RISI are dermatitis, ulcer, erosion and necrosis, which seriously affect the quality of life and treatment effect of tumor radiotherapy patients, and even affect the overall survival of patients. The pathological mechanism of RISI is still unclear. Some studies have shown that inflammation and oxidative stress are the main causes of RISI. RISI can be divided into acute and chronic RISI according to the different onset time, and different treatment strategies can be formulated according to the severity of the injury. In this article, clinical manifestations, classification, pathogenesis, prevention and treatment of RISI are comprehensively summarized.

Objective To investigate the changes of mitochondrial respiratory function during myocardial fibrosis in mice with myocardial infarction (MI) and its correlation with the increase of glycolytic flux. Methods Forty C57BL/6N mice were randomized into two equal groups to receive sham operation or ligation of the left anterior descending coronary artery to induce acute MI. At 28 days after the operation, 5 mice from each group were euthanized and left ventricular tissue samples were collected for transcriptomic sequencing. FPKM method was used to calculate gene expression levels to identify the differentially expressed genes (DEGs) in MI mice, which were analyzed using GO and KEGG databases to determine the pathways affecting the disease process. Heat maps were drawn to show the differential expressions of the pathways and the related genes in the enrichment analysis. In primary cultures of neonatal mouse cardiac fibroblasts (CFs), the changes in mitochondrial respiration and glycolysis levels in response to treatment with the pro-fibrotic agonist TGF-β1 were analyzed using Seahorse experiment. Results The mouse models of MI showed significantly increased diastolic and systolic left ventricular diameter (P<0.05) and decreased left ventricular ejection fraction (P<0.0001). A total of 124 up-regulated and 106 down-regulated DEGs were identified in the myocardial tissues of MI mice, and GO and KEGG enrichment analysis showed that these DEGs were significantly enriched in fatty acid metabolism, organelles and other metabolic pathways and in the mitochondria. Heat maps revealed fatty acid beta oxidation, mitochondrial dysfunction and increased glycolysis levels in MI mice. In the primary culture of CFs, treatment with TGF-β1 significantly reduced the basal and maximum respiratory levels and increased the basal and maximum glycolysis levels (P<0.0001). Conclusion During myocardial fibrosis, energy metabolism remodeling occurs in the CFs, manifested by lowered mitochondrial function and increased energy generation through glycolysis.
