| Objective:Observe the effects of lipid-lowering tablets Xiaoban unstable angina pectoris of coronary heart disease clinical efficacy of blood stasis phlegm heat And the MMP-9 and the expression of LDL-C levels, and to explore its mechanism.Methods:Will meet the inclusion criteria of unstable angina pectoris 60 cases of phlegm and blood stasis syndrome, Randomly divided into experimental group (30 cases) and control group (30 cases), Respectively, for four weeks, before and after treatment were observed in serum MMP-9 and changes in LDL-C and clinical efficacy, Adverse reactions were recorded, the last of the above results were statistically analyzed.Results:Before treatment, the experimental and control groups of serum MMP-9 and LDL-C of the water were significantly higher than normal levels, After treatment, the experimental group and control group serum MMP-9 and LDL-C of the water were significantly decreased compared with before treatment differences were statistically significant(P<0.05); After treatment, the experimental group decreased serum levels of MMP-9 compared with the control group a considerable effect(P>0.05), Experimental group, LDL-C levels lower than the control group(P |
