Aim To explore the relation between the protective effect of hyperoside(Hyp)on energy metab-olism and apoptosis in cardiomyocytes after myocardial infarction(MI)and the regulation of peroxisome pro-life rator-activated receptor α(PPARα)pathway.Methods Mouse myocardial infarction injury model was established by ligation of left anterior descending coronary artery.The mice that were successfully liga-ted were randomly divided into the following groups:MI group,Hyp(9,18 and 36 mg·kg-1)group,posi-tive fenofibrate group(120 mg·kg-1)and Hyp(36 mg·kg-1)+PPARα inhibitor GW6471 group.In addition,a sham group was set up,only threading with-out ligature.The mice were administered different kinds of drugs by gavage for seven days,once daily.ECG changes were recorded in mice 5 min before,5 min after surgery,and 1 hour after day 7 using the BL-420F biofunction system.The diagnostic ultrasound in-strument was used to examine the heart structure and function of each group of mice.The influence of myo-cardial histology was observed by hematoxylin and eo-sin (HE) staining and Sirius red(Sirius Red)stai-ning.The changes of creatine kinase isozymin-MB(CK-MB),cardiac troponin Ⅰ(cTnⅠ)and lactate de-hydrogenase(LDH)in mouse serum were assessed by ELISA kit.The expressions of PPARα signaling related proteins and apoptosis-related proteins were detected by immunofluorescence and Western blot.Results Compared with MI mice,Hyp could significantly im-prove the ECG abnormality of MI mice,increase the left ventricular ejection fraction(LVEF)and left ventricu-lar short axis shortening rate(LVFS),reduce serum cTnⅠ content,CK-MB and LDH activity,and reduce myocardial fibrosis,infarct area and cardiomyocyte ap-optosis in the MI area.Meanwhile,this research found that Hyp could activate PPARα signaling pathway and regulate apoptosis-related proteins.However,the car-dioprotective effect of hyperoside was reversed by the combination with the treatment of the PPARα signaling inhibitor,GW6471.Conclusions Hyp has an impro-ving effect on energy metabolism and apoptosis in mice after MI,and the mechanism may be related to its acti-vation of PPARα signaling pathway.

Objective This study focused on the preparation of air plasma-activated water and its application in the field of disinfection.By developing single-layer and double-layer dielectric barrier discharge(DBD)devices,we aimed to prepare plasma-activated liquid with high-efficiency disinfection ability.Methods We constructed single-layer and double-layer DBD devices using air as the working gas to generate activated water.The plasma temperature variation,discharge process and emission spectrum were captured and analyzed by a thermal imager,a time-resolved enhanced camera and a high-resolution spectrometer to evaluate the efficient energy conversion and particle excitation capabilities of the device.In addition,disinfection experiments were conducted on typical microorganisms such as Bacillus subtilis,Escherichia coli and Staphylococcus aureus to verify the disinfection effect of the activation solution.Results We adjusted the plasma treatment time for accurate disinfection of typical microorganisms such as Bacillus subtilis,Escherichia coli,and Staphylococcus aureus.Compared with a single-layer DBD device,the double-layer DBD device could produce higher concentrations of reactive species,significantly improving the disinfection effect of the activated liquid.Conclusion By using the air plasma activated water technology,an activated solution with highly efficient disinfection capability was successfully prepared.This study not only improves the disinfection efficiency,but also has potential environmental friendliness and economy,which provides a scientific basis and technical support for the application of plasma technology in the field of disinfection.

Fibroblast growth factor,as a critical protein regulating cell growth and differentiation,exhibits aberrant signaling closely associated with various pathological pathologies,including cancer.Among the members of the fibroblast growth factor family,fibroblast growth factor 9(FGF9)has been identified as a critical player in cancer initiation and progression.While numerous studies have investigated the molecular mechanisms of FGF9 individually,comprehensive reviews addressing its impact in cancer remain scarce.This article systematically reviews the functional mechanisms and regulatory networks of FGF9 in cancer,with a focus on its roles in common malignancies such as lung cancer,liver cancer,gastric cancer,colorectal cancer,breast cancer,and ovarian cancer.The aim is to facilitate translational research on FGF9 for targeted cancer diagnosis and therapy.

The combination of Aidi Injection(ADI) and doxorubicin(DOX) is a common strategy in the treatment of cancer, which can achieve synergistic anti-tumor effects while attenuating the cardiotoxicity caused by DOX. This study aims to investigate the mechanism of ADI in attenuating DOX-induced cardiotoxicity by multi-omics. DOX was used to induce cardiotoxicity in mice, and the cardioprotective effects of ADI were evaluated based on biochemical indicators and pathological changes. Based on the results, transcriptomics, proteomics, and metabolomics were employed to analyze the changes of endogenous substances in different physiological states. Furthermore, data from multiple omics were integrated to screen key regulatory pathways by which ADI attenuated DOX-induced cardiotoxicity, and important target proteins were selected for measurement by ELISA kits and immunohistochemical analysis. The results showed that ADI significantly reduced the levels of cardiac troponin T(cTnT) and N-terminal pro-B-type natriuretic peptide(NT-proBNP) and effectively ameliorated myocardial fibrosis and intracellular vacuolization, indicating that ADI showed therapeutic effect on DOX-induced cardiotoxicity. The transcriptomics analysis screened out a total of 400 differentially expressed genes(DEGs), which were mainly enriched in inflammatory response, oxidative stress, and myocardial fibrosis. After proteomics analysis, 70 differentially expressed proteins were selected, which were mainly enriched in the inflammatory response, cardiac function, and energy metabolism. A total of 51 differentially expressed metabolites were screened by the metabolomics analysis, and they were mainly enriched in multiple signaling pathways, including the inflammatory response, lipid metabolism, and energy metabolism. The integrated data of multiple omics showed that linoleic acid metabolism, arachidonic acid metabolism, and glycerophosphate metabolism pathways played an important role in DOX-induced cardiotoxicity, and ADI may exert therapeutic effects by modulating these pathways. Target validation experiments suggested that ADI significantly regulated abnormal protein levels of cyclooxygenase-1(COX-1), cyclooxygenase-2(COX-2), prostaglandin H2(PGH2), and prostaglandin D2(PGD2) in the model group. In conclusion, ADI may attenuate DOX-induced cardiotoxicity by regulating linoleic acid metabolism, arachidonic acid metabolism, and glycerophosphate metabolism, thus alleviating inflammation of the body.

This study aims to explore the impact of host plants on the quality of Taxilli Herba and provide a theoretical basis for the quality control of Taxilli Herba. The components of Taxilli Herba from three different host plants(Morus alba, Salix babylonica, and Cinnamomum cassia) and its 3 hosts(mulberry branch, willow branch, and cinnamon branch) were detected by widely targeted metabolomics based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). Principal component analysis(PCA), orthogonal partial least squares discriminant analysis(OPLS-DA), and Venn diagram were employed for analysis. A total of 717 metabolites were detected in Taxilli Herba from the three host plants and the branches of these host plants by UPLC-MS/MS. The results of PCA and OPLS-DA of Taxilli Herba from the three different host plants showed an obvious separation trend due to the different effects of host plants. The Venn diagram showed that there were 32, 8, and 26 characteristic metabolites in samples of Taxilli Herba from M. alba host, S. babylonica host, and C. cassia host, respectively. It was found by comparing the characteristic metabolites of Taxilli Herba and its hosts that each host transmits its characteristic components to Taxilli Herba, so that the Taxilli Herba contains the characteristic components of the host. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis showed that the differential metabolites of Taxilli Herba from the three hosts were mainly enriched in flavonoid biosynthesis, arginine and proline metabolism, and glycolysis/gluconeogenesis pathways. Furthermore, the differential metabolites enriching pathways of Taxilli Herba from the three hosts were different depending on the host. In a word, host plants have a significant impact on the metabolites of Taxilli Herba, and it may be an important factor for the quality of Taxilli Herba.

This study aims to systematically review and evaluate the quality of clinical research on the treatment of adenomyosis(AM) with traditional Chinese medicine(TCM) in recent ten years, using evidence graphs. Computer searches were conducted on eight Chinese and English databases, commonly used guideline databases, and guideline-related websites, covering the period from January 1, 2014, to October 1, 2024. Two researchers independently screened, extracted information, and evaluated the quality of the evidence. The distribution and quality of the clinical research evidence were presented using both text and charts. A total of 565 articles were included in the study, comprising 523 intervention studies, 23 observational studies, 18 systematic reviews/Meta-analysis, and 1 guideline. The overall publication volume has shown a downward trend in past two years. The sample sizes of the intervention and observational studies primarily focused on 60 to 120 cases. The intervention schemes mainly involved multi-therapy combinations, including 33 classic prescriptions and 25 Chinese patent medicines. Among these, 48 studies related to 17 classic prescriptions and 45 studies related to 10 types of Chinese patent medicines involved TCM syndrome types. Randomized controlled trial(RCT) tended to focus on overall clinical efficacy and the degree of dysmenorrhea as key outcome measures. Methodological quality issues were found in 97 RCTs related to TCM decoctions and 131 RCTs related to Chinese patent medicines, primarily involving unclear explanations of some information. The AMSTAR scores for the 18 systematic reviews/Meta-analysis ranged from 1 to 8 points, with 16 studies suggesting "evidence of potential therapeutic efficacy". The recommended level for the one included guideline was B-level. TCM shows significant advantages in treating AM. Future clinical research should further standardize study designs, reference relevant reporting guidelines, improve the quality of clinical research, generate higher-level evidence-based results, and promote the high-quality development of clinical research on TCM for treating AM.
