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

Ourresults show that the basal calcium binding was reduced in SHRs (P<0.01 vs WKY),while the maximalcalcium binding was not,but both typies calcium bindings had no significant change in RVHRs.Sodiumtanshinone Ⅱ-A sulfonate (125μ mol/L)have no effect on the calcium binding of ecythrocyte membraneof SHR in vitro.These data further support the hypothesis that there is a cell membrane abnormalitypresent in SHRs which may possibly serve as a marker genetics of in hypertension.展开更多

Methods： Randomized controlled trials（RCTs） of UAP treated by STS were searched in the China National Knowledge Infrastructure Database（CNKI）, VIP Database for Chinese Technical Periodicals（VIP）, Wanfang Database, the Chinese Biomedical Literature Database（CBM）, Web of Science, the Cochrane Library, Embase, and Pub Med, which from inception to January, 2016. The Cochrane Risk Assessment Tool was used to evaluate the methodological quality of the RCTs. The Review Manager 5.3 software was used to conduct the metaanalysis. Results： The results showed that 17 RCTs involving 1,372 patients were included. The meta-analysis indicated that the combined use of STS and Western medicine（WM） in the treatment of UAP can obviously improve the total effective rate [risk ratio（RR）=1.31, 95% confidence interval（CI）（1.24,1.39）, P〈0.0001], and the total effective rate of electrocardiogram [RR=1.43, 95% CI（1.30,1.56）, P〈0.0001], decrease the level of CRP [mean difference（MD）=–3.06, 95%CI（–3.85, –2.27）, P〈0.00001], fibrinogen [MD=–1.03, 95% CI（–1.16, –0.89）, P〈0.00001], and whole blood high shear viscosity [MD=–0.70, 95% CI（–0.92, –0.49）, P〈0.00001]. Additionally, the occurrence of adverse drug reaction of the experimental group was significantly higher than that of the control group [RR=3.57, 95% CI（1.28, 9.94）, P〈0.05]. Conclusions： Compared with WM, the combined use of STS was more effective.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
