ObjectiveThis study aims to explore the mechanism and targets of Shenfu Injection in regulating glycolysis to intervene in myocardial fibrosis in chronic heart failure based on the hypoxia-inducible factor-1α （HIF-1α）/ 6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 3 （PFKFB3） signaling pathway. MethodsA rat model of chronic heart failure was established by subcutaneous injection of isoproterenol （ISO）. After successful modeling， the rats were randomly divided into the Sham group， Model group， Shenfu injection （SFI， 6 mL·kg^-1） group， and inhibitor （3PO， 35 mg·kg^-1） group， according to a random number table， and they were treated for 15 days. Cardiac function was evaluated by echocardiography， and serum N-terminal pro-brain natriuretic peptide （NT-proBNP） levels were detected by enzyme-linked immunosorbent assay （ELISA）. Fasting body weight and heart weight were measured， and the heart index （HI） was calculated. Pathological changes in myocardial tissue were observed by hematoxylin-eosin （HE） and Masson staining， and the fibrosis rate was calculated. Biochemical assays were used to determine serum levels of glucose （GLU）， lactic acid （LA）， and pyruvic acid （PA）. Western blot was used to analyze the expression of proteins related to the HIF-1α/PFKFB3 signaling pathway （HIF-1α and PFKFB3）， glycolysis-related proteins （HK1， HK2， PKM2， and LDHA）， and fibrosis-related proteins ［transforming growth factor （TGF）-β₁， α-smooth muscle actin （α-SMA）， and Collagen type Ⅰ α1 （ColⅠA1）］. Real-time PCR was used to detect the mRNA expression of HIF-1α and PFKFB3 in myocardial tissue. ResultsCompared with the Sham group， the Model group showed significantly decreased left ventricular ejection fraction （LVEF）， left ventricular shortening fraction （LVFS）， interventricular septal thickness （IVSd）， and interventricular septal strain （IVSs） （P<0.05）， while left ventricular internal dimension at end-diastole （LVDd） and end-systole （LVIDs） were increased （P<0.05）. Serum NT-proBNP levels were significantly increased （P<0.01）， and body weight was decreased. Heart weight was increased， and the HIT index was increased （P<0.05）. Myocardial tissue exhibited inflammatory cell infiltration and collagen fiber deposition， and the fibrosis rate was significantly increased （P<0.05）. Serum GLU was decreased （P<0.05）， while LA and PA levels were increased （P<0.05）. Protein expressions of HIF-1α， PFKFB3， HK1， HK2， PKM2， LDHA， TGF-β₁， α-SMA， and ColⅠA1， as well as the mRNA expression of HIF-1α and PFKFB3 were increased （P<0.05）. Compared with the Model group， both the SFI group and 3PO groups showed significant improvements in LVEF， LVFS， IVSd， and IVSs （P<0.05） and decreases in LVDd， LVIDs， and NT-proBNP levels （P<0.05）. Body weight was significantly increased. Heart weight was significantly decreased， and the HIT index was significantly decreased （P<0.05）. Inflammatory cell infiltration， collagen fiber deposition， and the fibrosis rate were significantly decreased （P<0.05）. Serum GLU levels were significantly increased （P<0.05）， while LA and PA levels were decreased （P<0.05）. Expressions of glycolysis-related proteins， fibrosis-related proteins， and HIF-1α/PFKFB3 pathway-related proteins and mRNAs were significantly suppressed （P<0.05）. ConclusionSFI improves cardiac function in chronic heart failure by downregulating the expression of HIF-1α/PFKFB3 signaling pathway-related proteins， regulating glycolysis， and inhibiting myocardial fibrosis.

Objective:To develop a prediction model for postoperative prognosis in patients with cholangiocarcinoma(CCA)based on the expression of silence information regulator 2(SIRT2).Methods:The differential expression of SIRT2 between CCA and normal tissues was analyzed using TCGA and GEO databases.Gene set enrichment analysis(GSEA)was used to explore potential mechanisms of SIRT2 in CCA.The expression of SIRT2 protein in CCA tissues and normal tissues(including 44 pairs of specimens)was also detected by immunohistochemistry(IHC)in 89 resectable CCA patients who underwent surgical treatment in the First Affiliated Hospital of Bengbu Medical College between January 2016 and December 2021.The relationship between SIRT2 expression and clinicopathological characteristics and prognosis of CCA patients was analyzed.A survival prediction model for patients with resectable CCA was constructed with COX regression results,the calibration curve and the time-dependent receiver operating characteristic curve(ROC)were used to evaluate the performance of the constructed model,and the predictive power between this model and the American Joint Committee on Cancer(AJCC)/TNM staging system(8th edition)was compared.Results:SIRT2 mRNA was overexpressed in CCA tissues as shown in TCGA and GEO databases.IHC staining showed that SIRT2 protein expression in CCA tissues was significantly higher than that in adjacent non-tumor tissues.GSEA results showed that elevated SIRT2 expression may be involved in multiple metabolism-related signaling pathway,such as fatty acid metabolism,oxidative phosphorylation and amino acid metabolism.SIRT2 expression was related to serum triglycerides level,tumor size and lymph node metastasis(all P<0.05).The survival analysis results showed that patients with higher SIRT2 expression had a significantly lower overall survival(OS)than patients with lower SIRT2 expression(P<0.05).Univariate COX regression analysis suggested that pathological differentiation,clinical stage,postoperative treatment and SIRT2 expression level were associated with the prognosis of CCA patients(all P<0.05).Multivariate regression analysis confirmed that clinical stage and SIRT2 expression level were independent predictors of OS in postoperative CCA patients(both P<0.05).A nomogram based on SIRT2 for prediction of survival in postoperative CCA patients was constructed.The C-index of the model was 0.675,and the area under the time-dependent ROC curve(AUC)for predicting survival in the first,second,and third years was 0.879,0.778,and 0.953,respectively,which were superior to those of AJCC/TNM staging system(8th Edition).Conclusions:SIRT2 is highly expressed in CCA tissues,which is associated with poor prognosis in patients with resectable CCA.The nomogram developed based on SIRT2 may have better predictive power than the AJCC/TNM staging system(8th edition)in prediction of survival of postoperative CCA patients.

Parkinson's disease(PD)is a common neurodegenerative disorder prevalent among the elderly,characterized primarily by motor impairments and non-motor symptoms.In recent years,exercise therapy has gained widespread recognition for its efficacy in treating motor symptoms of PD as well as alleviating non-motor symptoms such as depression,anxiety,and improving quality of life.Traditional Chinese exercises have also garnered attention as a potential therapeutic approach.This paper provides an overview of recent research progress,with a focus on the roles of three types of traditional Chinese exercises—Wuqinxi,Baduanjin,and Tai Chi—in ameliorating both motor and non-motor symptoms in PD patients.It is hoped that this synthesis will contribute to the integration of traditional exercises into comprehensive treatment plans for PD,providing a reference basis for the scientific implementation of stand-ardized exercise programs and enhancing the feasibility and effectiveness of treatment.
