文摘Bone marrow mesenchymal stem cells (MSCs) have shown potential for cardiac repair following myocardial injury,but this approach is limited by their poor viability after transplantation.The present study was to investigate whether trimetazidine (TMZ) could improve survival of MSCs in an ex vitro model of hypoxia,as well as survival,differentiation,and subsequent activities of transplanted MSCs in rat hearts with acute myocardial infarction (AMI).MSCs at passage 3 were examined for their viability and apoptosis under a transmission electron microscope,and by using flow cytometry following culture in serumfree medium and exposure to hypoxia (5% CO2,95% N2) for 12 h with or without TMZ.Thirty Wistar rats were divided into 3 groups (n=10 each group),including groupⅠ(AMI control),groupⅡ (MSCs transplantation alone),and group Ⅲ (TMZ+MSCs).Rat MSCs (4×107) were injected into peri-infarct myocardium (MSCs group and TMZ+MSCs group) 30 min after coronary artery ligation.The rats in TMZ+MSCs group were additionally fed on TMZ (2.08 mg?kg-1?day-1) from day 3 before AMI to day 28 after AMI.Cardiac structure and function were assessed by echocardiography at 28th day after transplantation.Blood samples were collected before the start of TMZ therapy (baseline),and 24 and 48 h after AMI,and inflammatory cytokines (CRP,TNF-α) were measured.Then the sur-vival and differentiation of transplanted cells in vivo were detected by immunofluorescent staining.The cellular apoptosis in the peri-infarct region was detected by using TUNEL assay.Furthermore,apoptosis-related proteins (Bcl-2,Bax) within the post-infarcted myocardium were detected by using Western blotting.In hypoxic culture,the TMZ-treated MSCs displayed a two-fold decrease in apoptosis under serumfree medium and hypoxia environment.In vivo,cardiac infarct size was significantly reduced,and cardiac function significantly improved in MSCs and TMZ+MSCs groups as compared with those in the AMI control group.Combined treatment of TMZ with MSCs implantation demonstrated further decreased MSCs apoptosis,further increased MSCs viability,further decreased infarct size,and further improved cardiac function as compared with MSCs alone.The baseline levels of inflammatory cyto-kines (CRP,TNF-α) had no significant difference among the groups.In contrast,all parameters at 24 h were lower in TMZ+MSCs group than those in MSCs group.Furthermore,Western blotting indicated that the expression of antiapoptotic protein Bcl-2 was upregulated,while the proapoptotic protein Bax was down-regulated in the TMZ+MSCs group,compared with that in the MSCs group.It is suggested that implantation of MSCs combined with TMZ treatment is superior to MSCs monotherapy for MSCs viability and cardiac function recovery.

Results: Before treatment, the LVESD, LVEDD and LVEF levels between observation group and the control group had no significant difference (P>0.05);Compared with before treatment, LVESD and LVEDD levels in the observation group and control group after treatment were significantly decreased, LVEF increased significantly, and there were significant differences (P<0.05);After treatment, the observation group LVESD and LVEDD were lower than the control group, LVEF in the observation group after treatment was higher than the control group, and the differences were statistically significant (P<0.05). Before treatment, SOD and MDA between the observation group and the control group had no significant difference (P>0.05);After treatment, SOD in the observation group and the control group were significantly increased, MDA decreased significantly, and the differences were statistically significant (P<0.05);After treatment, SOD in the observation group was higher than the control group, MDA in the observation group was lower than the control group, and the differences were statistically significant (P<0.05). Before treatment, CRP, TNF-α, and IL-6 between the observation group and the control group had no significant difference (P>0.05);compared with before treatment, the CRP, TNF-α, and IL-6 of observation group and control group after treatment were significantly decreased, and the differences were statistically significant (P<0.05);After treatment, CRP, TNF-α, and IL-6 of the observation group were lower than the control group, and the difference was statistically significant (P<0.05).Conclusions:Atorvastatin combined with trimetazidine can more significantly improve cardiac function in patients with coronary heart disease, reduce oxidative stress and inflammation.
文摘ABSTRACT Objective:To study the protective effect of trimetazidine on myocardial ischemia reperfusion injury in ovariectomized rats and the effect on Fas and FasL gene expression.Methods:Female Wistar rats were selected and divided into ovariectomized model group (OVX group), ovariectomized + ischemia reperfusion model group (OVX+I/R group) and ovariectomized + ischemia reperfusion + trimetazidine intervention group (OVX+I/R+TMZ group) (n=8), and the content of serum myocardial enzymes and structural proteins, hemodynamic indexes and the expression levels of apoptotic molecules and autophagy genes in myocardial tissue were determined.Results:Serum creatine kinase (CK) and isoenzyme (CK-MB), lactate dehydrogenase (LDH),α-hydroxybutyrate dehydrogenase (α-HBDH) content, troponin I (cTnI) and troponin T (cTnT) content as well as LVEDP level of OVX+I/R group were significantly higher than those of OVX group (P<0.05) while LVSP,+dp/dtmax and-dp/dtmax levels were significantly lower than those of OVX group (P<0.05), and serum CK, CK-MB, LDH,α-HBDH, cTnI and cTnT content as well as LVEDP level of OVX+I/R+TMZ group were significantly lower than those of OVX+I/R group (P<0.05) while LVSP,+dp/dtmax and-dp/dtmax levels were significantly higher than those of OVX+I/R group (P<0.05). Fas, FasL, Beclin-1 and P62 expression levels as well as LC3II/LC3I ratio in myocardial tissue of OVX+I/R group were significantly higher than those of OVX group (P<0.05), and Fas, FasL, Beclin-1 and P62 expression levels as well as LC3II/LC3I ratio in myocardial tissue of OVX+I/R+TMZ group were significantly lower than those of OVX+I/R group (P<0.05). Conclusions:Trimetazidine has protective effect on myocardial ischemia reperfusion injury in ovariectomized rats, and inhibiting cell apoptosis and cell autophagy mediated by Fas/FasL is the molecular mechanism for trimetazidine to play the protective role.
文摘Background: Organic cellular inflammatory response constitutes a pathophysiological mechanism present in all Coronary Artery Bypass Graftings (CABGs). In this aspect, the organism brings forth its defenses through answers that involve cellular components. Objectives: To evaluate, in a randomized double-blind prospective study, controlled with placebo, the effects of trimetazidine (Tmz) on cellular response, analyzed through the variation of leukocytes, neutrophils and monocytes. Patients and Method: 30 patients were randomly selected to be studied, with no more than a mild ventricular dysfunction, and divided into two groups (Tmz and placebo) stratified by echocardiography and receiving medication/placebo in a 60 mg/day dose. The samples of leukocytes, neutrophils and monocytes were obtained in the pre-operatory day without medication, at surgery day with 12 to 15 days of medication/placebo, with 5 minutes after the aortic declamping, and within 12, 24 and 48 hours after surgery. Results: The leukocytes and neutrophils levels have decreased significantly in the treated group when compared to the control group, in all analyzed moments (p = 0.012;p = 0.005). Conclusions and Clinical Implications: Trimetazidine has proved to reduce significantly the levels of total leukocytes and neutrophils in patients submitted to CABG.
