Twelve neonatal clean grade Wistar rats were selected. The cardiomyocytes were isolated, cultured and divided according to different treatments in the medium. The cardiomyocyte size was determined by phase contrast microscope, and the rate of protein synthesis was measured by [3H]-Leucine incorporation. The c-fos and c-jun mRNA expression in cardiomyocytes was detected by reverse transcription polymerase chain reaction （RT-PCR）. It was found after cardiomyocytes were treated with AngⅡ for 30 min, the c-fos and c-jun mRNA expression in cardiomyocytes was increased significantly （P〈0.01）. After treatment with AngⅡ for 24 h, the rate of protein synthesis in AngⅡ group was significantly increased as compared with control group （P〈0.01）. After treatment with AngⅡ for 7 days, the size of cardiomyocytes in AngⅡ group was increased obviously as compared with control group （P〈0.05）. After pretreatment with STS or Valsartan before AngⅡ treatment, both of them could inhibit the above effects of AngⅡ （P〈0.05 or P〈0.01）. It was suggested that STS could ameliorate AngⅡ-induced cardiomyocyte hy- pertrophy by inhibiting c-fos and c-jun mRNA expression and reducing protein synthesis rate of cardiomyocytes.展开更多

METHODS: The medical records of 96 patients with acute heart failure were randomly divided into 2 groups(48 cases in observation group and 48 cases in control group). The control group was treated with conventional western medicine, and the observation group was treated with Tanshinone IIA sulfonic acid natrium on the basis of western medicine. The traditional Chinese medicine(TCM) syndromes scores before and after treatment(after 28 d of treatment), clinical efficacy, and cardiac echocardiographic indexes and serum biochemical indicators before and after treatment were observed in the 2 groups. RESULTS: After treatment, the scores of TCM syndromes in the 2 groups were significantly decreased(P < 0.05), and the change in observation group was significantly greater than that in control group(P < 0.05). The total clinical effective rate in observation group was significantly higher than that in control group(91.67% vs 75.00%)(P < 0.05). After treatment, the echocardiographic indexes of left ventricular end-diastolic diameter(LVEDD) and left ventricular end-systolic diameter(LVESD) values were significantly reduced in the 2 groups while the left ventricular ejection fraction(LVEF) and stroke volume(SV) value were significantly increased, and the changes in observation group were significantly larger than those in control group(P < 0.05). After treatment, the levels of serum nuclear factor-kappaB(NF-KB), interleukin-1β(IL-1β) and N-terminal pro-brain natriuretic peptide(NT-proBNP) were significantly decreased in the 2 groups(P < 0.05), while the 6-keto-prostaglandin F1α(6-ketoPGF1α) level was significantly increased. And the changes in observation group were significantly greater than those in control group(P < 0.05). CONCLUSION: Tanshinone combined with western medicine can significantly improve the clinical symptoms of patients with acute heart failure, improve cardiac function, reduce the myocardial damage degree, and effectively reduce the risk of short-term recurrence and death, and it has exact clinical efficacy.展开更多

Methods： In the primary culture of neonatal rat myocardial cells, the total protein content in myocardial cells was determined by coomassie brilliant blue and the protein synthesis rate was measured by [3H]-Leucine incorporation as indexes for hypertrophy of myocardial cells. The expression of p-ERK1/2 was determined using Western blot and immunofluorescence labeling. Results： （1） The total protein and protein synthesis rate increased significantly in contrast to the control group after the myocardial cells were stimulated by Ang Ⅱ （1 μ mol/L） for 24 h; STS markedly inhibited the increment of the total protein level induced by Ang Ⅱ and the syntheses of protein. （2） After pretreatment of myocardial cells with Ang Ⅱ （1 μmol/L） for 5 min, the p-ERK1/2 protein expression was increased, with the most obvious effect shown at about 10 min; pretreatment of myocardial cells with STS at different doses （2, 10, 50μmol/L） for 30 min resulted in obvious inhibition of the expression of p-ERK1/2 stimulated by Ang Ⅱ in a dose-dependent manner. （3） After the myocardial cells were stimulated by AngⅡ （1 μ mol/L）, the immunofluorescence of ERK1/2 rapidly appeared in the nucleus. The activation and translocation process of ERK1/2 induced by Ang Ⅱ was blocked distinctly by STS. （Conclusion： STS inhibited the myocardial cell hypertrophy induced by Ang Ⅱ, and the mechanism may be associated with the inhibition of p-ERK1/2 expression.展开更多

Methods： The effect of STS on cytotoxicity was evaluated using the 3-（4,5-dimethylthiazol-2-yl）-3,5- phenytetrazoliumromide （MTT） assay. As indexes for cardiocyte hypertrophy, cell size was determined by phase contrast microscopy and protein synthesis rate was measured by 3H-leucine incorporation. The proto-oncogene c-fos mRNA expression of cardiocytes was assessed using reverse transcription polymerase chain reaction （RT-PCR）. Results： STS could inhibit cardiocyte hypertrophy, increase the protein synthesis rate and enhance proto-oncogene c-fos mRNA expression in cardiocytes induced by Ang Ⅱ（P〈0.01）, with an effect similar to that of Valsartan, the Ang Ⅱ receptor antagonist. Conclusion： STS can prevent the hypertrophy of cardiac myocytes induced by Ang Ⅱ, which may be related to its inhibition of the expression of proto-oncogene c-fos mRNA.展开更多

Randomized controlled trials(RCTs) comparing STS plus conventional treatment with conventional treatment were retrieved.Study screening, data extraction, quality assessment, and data analysis were conducted in accordance with the Cochrane standards.RESULTS: Sixteen trials involving 1383 people were included. The Meta-analysis showed STS combined with conventional treatment was a better treatment option than conventional treatment alone in reducing the risk of mortality, heart failure, arrhythmia and shock. In addition, STS was associated with improvement in left ventricular ejection fraction(LVEF) and left ventricular end diastolic dimension(LVEDD). No significant difference of STS was found on recurrent angina and recurrent AMI. However,the safety of STS remained uncertain for limited data.CONCLUSION: Compared with conventional treatment alone, STS combined with conventional treatment may provide more benefits for patients with AMI. Due to the fact that the overall quality of all included trials is generally low, further large-scale high quality trials are warranted.展开更多
