ABSTRACT
Objective@#To observe the clinical efficacy and safety of trimetazidine combined with ticagrelor in the treatment of unstable angina pectoris (UAP) complicated with chronic heart failure (CHF).@*Methods@#From January 2016 to September 2018, 60 UAP patients complicated with CHF in Taizhou Cancer Hospital were selected and randomly divided into two groups according to the random number table method, with 30 cases in each group.The control group was given ticagrelor, while the observation group was given ticagrelor + trimetazidine.The clinical efficacy, angina attack, cardiac function indicators, adverse reactions were compared between the two groups.@*Results@#The total effective rate of the observation group was 96.67%, which was higher than 80.00% of the control group (χ2=4.043, P<0.05). With in 3 months after treatment, the number of angina attacks (6.59±1.32)times and the duration of single angina pectoris [(2.24±0.92)min] in the observation group were all lower than those in the control group(t=4.277, 4.076, all P<0.05). After treatment, the left ventricular ejection fraction [(49.36±6.25)%] and stroke output [(76.29±5.31)mL] of the observation group were higher than those of the control group (t=4.066, 4.093, all P<0.05), and the level of brain natriuretic peptide [(378.32±27.82)μg/L] of the observation group was lower than that of the control group (t=4.152, P<0.05). The incidence rate of adverse reactions of the observation group was 6.67%, which of the control group was 3.33%, there was no statistically significant difference between the two groups (χ2=0.351, P>0.05).@*Conclusion@#The combination of ticagrelor and trimetazidine can effectively reduce the attack of angina pectoris, improve cardiac function and has less adverse reactions.It is effective and safe for UAP patients complicated with CHF.
ABSTRACT
Objective:To investigate the effect of P53 inhibitors and microtubule inhibitors on nuclear translocation of glucocorticoid receptor in psoriatic epidermal keratinocytes.Methods: Isolate and culture psoriatic and normal epidermal keratinocytes.The keratinocytes were incubated with P53 inhibitors and microtubule inhibitors with or without vascular endothelial growth factor( VEGF) ,and then detected the distribution of GR by indirect immunofluorescence.Results:VEGF induced nuclear trans-location of GR in normal keratinocytes, and the P53 inhibitor restrained VEGF induced nuclear export of GR in normal keratinocytes.The nuclear translocation score of the keratinocytes cultured with VEGF was significantly lower than that of keratinocytes cultured without VEGF(P<0.05).The microtubule inhibitors could completely detained GR of normal epidermal keratinocytes in the cytoplasm,and there′s no significantly increased of the level of GR in the cytoplasm after putting VEGF into the normal epidermal kera-tinocytes.While the microtubule inhibitors and P53 inhibitors co-cultured, there will be a small amount of GR into the keratinocyte nuclei.Conclusion:Microtubule mediated uptake of GR,P53 participated nuclear export of GR.
