| 目的 探讨微小RNA-133在慢性心力衰竭(CHF)患者血清中表达及与心肌重构和心功能相关性。方法 选取CHF患者136例,根据美国NYHA分级标准分为:Ⅰ～Ⅱ级45例、Ⅲ级53例、Ⅳ级38例；同期,从体检中心选取健康者50例作为对照组。所有研究对象均行超声心动图检查,检测血清中N末端B型钠肽原(NT-proBNP)水平和血清中miR-133表达。结果 CHF患者血清NT-proBNP水平、miR-133a和miR-133b表达量均高于对照组,Ⅳ级患者血清NT-proBNP水平、miR-133a和miR-133b表达量均高于Ⅲ级和Ⅰ～Ⅱ级,且Ⅲ级均高于Ⅰ～Ⅱ级,差异有统计学意义(P<0.05)；CHF患者左室舒张末内径(LVEDD)、左心房内径(LAP)、左心室后壁厚度(LVPW)和左室质量指数(LVMI)均较对照组增加,而左室重构指数(LVRI)、心输出量(CO)和左室射血分数(LVEF)均较对照组减少,差异有统计学意义(P<0.05),Ⅰ～Ⅱ级患者LAP、LVPW和LVMI均低于Ⅲ级和Ⅳ级,且Ⅲ级均低于Ⅳ级,LVRI、CO和LVEF均高于Ⅲ级和Ⅳ级,且Ⅲ级均高于Ⅳ级,差异有统计学意义(P<0.05)；Pearson相关分析显示,CHF患者血清中miR-133a表达量与NT-proBNP、LAP、LVPW和LVMI呈正相关(r=0.801、0.620、0.346和0.313,P<0.05),而与CO和LVEF呈负相关(r=-0.335和-0.523,P<0.05),血清中miR-133b表达量与NT-proBNP、LAP、LVPW和LVMI呈正相关(r=0.732、0.593、0.371和0.266,P<0.05),而与LVRI 、CO和LVEF呈负相关(r=-0.194、-0.260和-0.543,P<0.05)。结论 miR-133a和miR-133b在CHF患者血清中表达量升高,与心肌重构和心脏功能密切相关。 |

| Objective To investigate the expression of miR-133 in the serum of patients with chronic heart failure(CHF) and its correlation with myocardial remodeling and cardiac function.Methods A hundred and thirty-six cases of patients with CHF were selected,and were assigned into different groups according to American NYHA classification standards:Ⅰ~Ⅱ grade 45 cases,Ⅲ grade 53 cases and Ⅳ grade 38 cases.During the same period,50 cases of health were selected as the control group.All subjects took echocardiographic examination.The levels of N-terminal B-type natriuretic peptide(NT-proBNP) and miR-133 were detected.Results The serum levels of NT-proBNP and expression levels of miR-133a and miR-133b in patients with CHF were higher than the control group;the serum levels of NT-proBNP and expression levels of miR-133a and miR-133b in Ⅳ grade patients were higher than Ⅲ grade and Ⅰ~Ⅱ grade,and Ⅲ grade were higher than Ⅰ~Ⅱ grade.The differences were statistically significant(P<0.05).The LVEDD,LAP,LVPW and LVMI in patients with CHF were increased,while LVRI,CO and LVEF were decreased compared with the control group.The differences were statistically significant(P<0.05).The LAP,LVPW and LVMI in Ⅰ~Ⅱ grade patients were lower than Ⅲ grade and Ⅳ grade,and Ⅲ grade were lower than Ⅳ grade;LVRI,CO and LVEF were higher than Ⅲ grade and Ⅳ grade,and Ⅲ grade were higher than Ⅳ grade.The differences were statistically significant(P<0.05).Pearson correlation analysis showed that the expression levels of miR-133a in patients with CHF were positively correlated with NT-proBNP,LAP,LVPW and LVMI(r=0.801,0.620,0.346 and 0.313,P<0.05),while were negatively correlated with CO and LVEF(r=-0.335 and -0.523, P<0.05);the expression levels of miR-133b in patients with CHF were positively correlated with NT-proBNP,LAP,LVPW and LVMI(r=0.732,0.593,0.371 and 0.266,P<0.05),while were negatively correlated with LVRI,CO and LVEF(r=-0.194,-0.260 and -0.543,P<0.05).Conclusions The expression levels of miR-133a and miR-133b in serum of patients with CHF were increased,which were closely related with myocardial remodeling and cardiac function. |
