ObjectiveTo validate the therapeutic effect of Yinqi Sanhuang Jiedu decoction （YQSH） on a mouse model of carbon tetrachloride （CCl₄）-induced liver fibrosis and to investigate its correlations with the Piezo-type mechanosensitive ion channel component 1 （Piezo1）-Yes-associated protein （YAP） mechanical signaling axis and macrophage polarization. MethodsFifty-four C57BL/6J mice were randomized into a blank control group， a 4-week model group， a 6-week model group， a 8-week model group， a positive drug （silymarin， 55 mg·kg^-1·d^-1） group， and low-， medium-， and high-dose （8.325， 16.65， 33.3 g·kg^-1·d^-1， respectively） YQSH groups. Except the 6-week model group （n=12）， each of the other groups had 6 mice. Mice in other groups except the blank control group received intraperitoneal injections of 10% CCl₄ twice weekly for the modeling of liver fibrosis. Drug interventions began one week after the initial modeling through gavage， and the blank control and model groups received 0.2 mL of normal saline via gavage. The histopathological changes and collagen deposition in the liver were observed via hematoxylin-eosin （HE）， Masson's trichrome， and Sirius red staining. Serum activities of alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， as well as serum levels of total protein （TP）， albumin （ALB）， total bilirubin （TBIL）， hyaluronic acid （HA）， laminin （LN）， procollagen type Ⅲ （PCⅢ）， and collagen type Ⅳ （Ⅳ-C）， were measured. The levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in the liver tissue were determined by enzyme-linked immunosorbent assay （ELISA）. The protein and mRNA levels of Piezo1 and YAP1 in the liver tissue were determined by immunohistochemistry （IHC） and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， respectively. Co-localization of Piezo1 with YAP1， and YAP1 with inducible nitric oxide synthase （iNOS） was observed by the immunofluorescence （IF） assay. The proportions of M1-type （F4/80⁺CD80⁺） and M2-type （F4/80⁺CD206⁺） macrophages in the liver tissue were examined by flow cytometry. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses and gene set enrichment analysis （GSEA） were performed through transcriptomic sequencing. ResultsCompared with the blank control group， the model group exhibited gradually worsened liver fibrosis at the 4^th， 6^th， and 8^th weeks. The 6- and 8-week model groups showcased inflammatory cell infiltration and collagen deposition in the liver （P<0.01） and upregulated protein levels of both Piezo1 and YAP1 （P<0.01）. Compared with the model groups， treatment with YQSH improved the liver function （P<0.05， P<0.01）， alleviated liver fibrosis （P<0.05， P<0.01）， and reduced intrahepatic inflammatory cell infiltration and collagen deposition （P<0.01）. Furthermore， the treatment downregulated the protein and mRNA levels of Piezo1 and YAP1 （P<0.05， P<0.01）， lowered the levels of inflammatory factors TNF-α and IL-1β （P<0.05， P<0.01）， and decreased the ratio of CD80 （M1-type）/CD206 （M2-type） macrophage proteins （P<0.01）. The IF assay showed co-localization of YAP1 with Piezo1 and iNOS. Compared with the model groups， YQSH treatment downregulated the expression of Piezo1， YAP1， and iNOS （P<0.05， P<0.01）. Transcriptomic analysis suggested that the anti-liver fibrosis effect of YQSH may be related to the Hippo signaling pathway （P<0.05）. ConclusionThe anti-liver fibrosis effect of YQSH may be related to its inhibition of the Piezo1-YAP signaling axis and regulation of macrophage polarization.

Objective:To explore the possible anti-atherosclerotic mechanisms of glucose co-transporter-2 inhibitor canagliflozin.Methods:ApoE -/-mice fed on Western diet were randomly assigned into the model group ( n=10) and the canagliflozin group ( n=10). C57BL/6J mice fed on normal diet were chosen as the control group ( n=10). Mice in the canagliflozin group were gavaged with canagliflozin for 14 weeks. The presence and severity of atherosclerosis were evaluated with HE and oil red O stainings in aortic root section slices. PCR assay was performed to determine the mRNA expression levels of nitric oxide synthase. Hepatic transcriptome analysis and hepatic amino acid detection were conducted using RNA-seq and targeted LC-MS, respectively. Results:HE staining and oil red O staining of the aortic root showed that AS models were successfully established in ApoE -/-mice fed on Western diet for 14 weeks. Canagliflozin alleviated the severity of atherosclerosis in pathology. Hepatic transcriptome analysis indicated that canagliflozin impacted on amino acid metabolism, especially arginine synthesis in ApoE -/-mice. Targeted metabolomics analysis of amino acids showed that canagliflozin reduced hepatic levels of L-serine, L-aspartic acid, tyrosine, L-hydroxyproline, and L-citrulline, but raised the hepatic level of L-arginine. Compared to the model group, the canagliflozin group exhibited higher serum arginine and nitric oxide levels as well as elevated nitric oxide mRNA expression in aortic tissues ( P<0.05). Conclusion:Canagliflozin regulated the amino acid metabolism, reduced the levels of glucogenic amino acids,and promoted the synthesis of arginine in atherosclerotic mice.

Diabetes mellitus is a chronic metabolic disease characterized by elevated blood glucose due to insufficient insulin secretion or insulin resistance.According to traditional Chinese medicine,diabetes mellitus is classified as"Xiaoke disease"in Chinese medicine,and its basic pathogenesis is yin deficiency and fluids.With the continuous improvement and development of traditional Chinese medicine theory,more and more doctors generally believe that"hot"runs through the occurrence and development of diabetes and the heat-clearing method is the key to the treatment of diabetes.The theory of the efficacy of traditional Chinese medicine believes that heat-clearing Chinese medicine has the effect of clearing heat and reducing fire,and its own effect of reducing heat and preserving Yin,which is in line with the principle of traditional Chinese medicine treatment of diabetes.Therefore,in this paper,we summarize the research progress on the role and mechanism of heat clearing herbs in the prevention and treatment of diabetes,mainly related to protection of pancreatic β-cell function,improvement of insulin resistance,inhibition of glucosidase activity,reduce the inflammatory response,relieve oxidative stress and regulation of intestinal flora,and analyze the problems and development trend of the current research,in order to provide a scientific and theoretical basis for the drug development and clinical application of heat clearing traditional Chinese medicine in the prevention and treatment of diabetes.
