ObjectiveTo investigate the effect of Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma on ferroptosis in the rat model of myocardial infarction and further elucidate its role in myocardial remodeling. MethodsThe rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. The 50 successfully modeled rats were randomly divided into model group， ferroptosis inhibitor group （2 mg·kg^-1）， enalapril group （2.1 mg·kg^-1）， and low- and high-dose （4 g·kg^-1 and 8 g·kg^-1， respectively） Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma， with 10 rats in each group. The rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. After 4 weeks of treatment， echocardiography was used to assess the cardiac structure and function. Hematoxylin-eosin （HE） staining and Masson staining were employed to observe pathological morphology and fibrosis of the myocardial tissue. Serum levels of N-terminal pro-B-type natriuretic peptide （NT-proBNP）， transforming growth factor-β （TGF-β）， and myosin heavy chain-β （MHC-β） were measured by enzyme-linked immunosorbent assay （ELISA）. Prussian blue staining was performed to detect myocardial iron deposition. The myocardial mitochondrial structure was observed by transmission electron microscopy. Levels of malondialdehyde （MDA） and glutathione （GSH） in the myocardial tissue were determined by lipid peroxidation assay kits. Immunofluorescence assay was conducted to observe the fluorescence intensity of nuclear factor E₂-related factor 2 （Nrf2） in the myocardial tissue. Western blot analysis was performed to evaluate the expression levels of proteins in the Nrf2/solute carrier family 7 member 11 （SLC7A11）/glutathione peroxidase 4 （GPX4） pathway. ResultsCompared with the sham group， the model group showed increased left ventricular end-diastolic diameter （LVEDD）， left ventricular end-systolic diameter （LVESD）， and serum levels of NT-proBNP， TGF-β， and MHC-β （P<0.01）， decreased left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） （P<0.01）， disarrangement of myocardial cells， inflammatory cell infiltration， severe myocardial fibrosis， increased myocardial iron deposition， and irregular mitochondrial morphology with vacuolation. Furthermore， the modeling led to increased MDA （P<0.01）， decreased GSH （P<0.01）， diminished Nrf2 fluorescence intensity in the myocardial tissue， and downregulated expression levels of Nrf2， SLC7A11， and GPX4 （P<0.01）. Compared with the model group， Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma reduced the LVEDD， LVESD， and serum levels of NT-proBNP， TGF-β， and MHC-β （P<0.05， P<0.01）， increased the LVEF and LVFS （P<0.05， P<0.01）， alleviated pathological changes such as myocardial cell disarrangement， inflammatory cell infiltration， myocardial fibrosis， and iron deposition， lowered the level of MDA （P<0.05， P<0.01）， raised the level of GSH （P<0.05， P<0.01）， improved the mitochondrial morphology and reduced vacuolation in the myocardial tissue， enhanced Nrf2 fluorescence intensity， and upregulated the expression levels of Nrf2， SLC7A11， and GPX4 （P<0.05， P<0.01） in the rat model of myocardial infarction. ConclusionGardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma alleviates pathological damage and myocardial remodeling in the rat model of myocardial infarction by inhibiting ferroptosis， the mechanism of which is related to the activation of Nrf2/SLC7A11/GPX4 signaling pathway.

Objective To investigate the regulatory effect of miR-372 on Runx2 expression and its impact on osteoblast mineralization.Methods Bioinformatic software(Target Scan,miRanda,RNAhybrid)was used to predict microRNAs(miRNAs)that target Runx2,the binding ability of miR-372 to Runx2 was confirmed by dual-luciferase reporter gene experiments.Western blotting analysis was performed to evaluate the regulatory effects of miR-372 on Runx2 protein expression.Osteoblast mineralization was induced using ascorbic acid andβ-glycerophosphate treatment.The functional impact of miR-372 mediated Runx2 regulation on osteoblast mineralization was assessed by measuring Alkaline Phosphatase(ALP)activity and mineralized nodules formation.Results Dual-luciferase reporter gene experiments confirmed direct binding of miR-372 to the Runx2.Western blotting indicated that overexpression of miR-372 in transfected osteoblasts signficantly suppressed Runx2 protein expression,while silencing miR-372 led to elevated Runx2 protein levels.After mineralization induction,ALP activity and mineralization quantitative detection showed miR-372 reuced ALP activity(P＜0.05)and inhibited minerali-zation(P＜0.05)by suppressing Runx2 expression,which was more obvious especially after Runx2 silencing.Conclusion miR-372 can inhibits osteoblast mineralization by downregulating Runx2 expression.

OBJECTIVE To explore the effect and mechanism of the alcoholic extract from Scabiosa comosa against hepatic fibrosis （HF）. METHODS Intragastrical administration of carbon tetrachloride was given to induce HF model. By observing the pathological changes in liver tissue， mRNA and protein expressions of HF indexes [α-smooth muscle actin （α-SMA）， collagen type Ⅰ] and phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） pathway-related factors were detected， and the improvement effects and possible mechanism of low-dose， medium-dose and high-dose （50， 100， 200 mg/kg） of alcoholic extract from S. comosa on HF model rats were investigated. Drug-containing serum was prepared by intragastrical administration of alcoholic extract from S. comosa at a concentration of 1 800 mg/（kg·d） （calculated by the amount of raw material）. The effects of drug- containing serum of alcoholic extract from S. comosa on the expression of miRNA-21 were observed through the intervention of HSC-T6 cells with low， medium and high concentrations of drug-containing serum of alcoholic extract from S. comosa （diluted to 10%， 15%， 20%）. miRNA-21 mimics or inhibitors were used to transfect HSC-T6 cells， and the mRNA and protein expressions of factors related to the PI3K/Akt signaling pathway were detected. RESULTS The results of in vivo experiments showed that low， medium and high doses of alcoholic extract from S. comosa significantly ameliorated the histopathological changes in liver tissue of HF rats， and the percentage of collagen was significantly reduced （P＜0.01）； mRNA and protein expressions of the indicators related to HF as well as PI3K and Akt were significantly reduced （P＜0.01）， and mRNA and protein expressions of phosphatase and tensin homolog deleted on chromosome ten （PTEN） were increased in liver tissue of rats （P＜0.01）. The results of in vitro experiments showed that drug-containing serum of alcoholic extract from S. comosa significantly inhibited the expression of miRNA-21 at low， medium and high concentrations （P＜0.01）； whereas after transfection with miRNA-21 mimics， it was found that miRNA-21 mimics significantly increased mRNA and protein expressions of PI3K and Akt （P＜0.01）， while significantly decreased mRNA and protein expressions of PTEN （P＜0.01）； after transfection with miRNA-21 inhibitor， the changes of above indexes were opposite to the above results （P＜0.01）. CONCLUSIONS Alcoholic extracts of S. comosa may inhibit the PI3K/Akt signaling pathway by affecting the expression of miRNA-21， so as to achieve the effect of anti-hepatic fibrosis.
