摘要:

目的 探讨小而密低密度脂蛋白胆固醇(sd-LDL-C)检测在4种心脑血管系统相关疾病[冠心病、2型糖尿病(T2DM)、高血压和脑梗死]中的意义。方法 选取单纯高血压患者50例、单纯T2DM患者90例、脑梗死患者110例及冠心病患者129例,以体检健康者104名作为正常对照组。检测所有对象血糖(Glu)、载脂蛋白A1(apo A1)、载脂蛋白B(apo B)、载脂蛋白E(apo E)、总胆固醇(TC)、三酰甘油(TG)、同型半胱氨酸(Hcy)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、sd-LDL-C。采用Spearman相关分析评价sd-LDL-C与其他指标的相关性。结果 与正常对照组比较,高血压组apo B、TC、Glu、sd-LDL-C水平明显升高(P<0.05);脑梗死组TG、Hcy水平明显升高(P<0.05),apo A1、apo B、apo E、LDL-C水平明显降低(P<0.05);T2DM组TC、Glu、TG、Hcy、sd-LDL-C水平明显升高(P<0.05),apo A1水平明显降低(P<0.05);冠心病组TC、Glu、TG、Hcy水平明显升高(P<0.05),apo A1水平明显降低(P<0.05)。在冠心病组中,sd-LDL-C与apo A1、apo B、apo E、TC和LDL-C呈正相关(r值分别为0.372、0.316、0.248、0.718、0.316,P<0.05),与HDL-C呈负相关(r=-0.218,P<0.05)。在T2DM组中,sd-LDL-C与apo A1、apo B、apo E、TC、TG和LDL-C呈正相关(r值分别为0.243、0.779、0.416、0.616、0.614、0.678,P<0.05)。在高血压组中,sd-LDL-C与TC、TG和LDL-C呈正相关(r值分别为0.623、0.756、0.699,P<0.05),与HDL-C呈负相关(r=-0.355,P<0.05)。在脑梗死组中,sd-LDL-C与apo A1、apo E、TG呈正相关(r值分别为0.398、0.117、0.271,P<0.05)。结论 T2DM及高血压患者血清sd-LDL-C水平升高。sd-LDL-C在心脑血管系统相关疾病中有一定意义。

Abstract:

Objective To investigate the role of small and dense low-density lipoprotein cholesterol (sd-LDL-C) in 4 kinds of cardiovascular and cerebrovascular diseases [coronary heart disease,type 2 diabetes mellitus(T2DM),hypertension and cerebral stroke]. Methods A total of 50 patients with hypertension,90 patients with T2DM,129 patients with coronary heart disease and 110 patients with cerebral stroke were enrolled as disease group. Totally,104 healthy subjects were enrolled as healthy control group. The levels of blood glucose (Glu), apolipoprotein A1(apo A1),apolipoprotein B(apo B),apolipoprotein E(apo E), total cholesterol(TC),triglyceride(TG),homocysteine(Hcy),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and sd-LDL-C were determined in disease and control groups. The relationship was evaluated by Spearman correlation analysis. Results The apo B,TC,Glu and sd-LDL-C levels in hypertension group were higher than those in control group (P<0.05). The TG and Hcy levels in cerebral stroke group were higher than those in control group (P<0.05),and the apo A1,apo B,apo E and LDL-C levels were lower (P<0.05). The TC,Glu,TG,Hcy and sd-LDL-C levels in T2DM group were higher than those in control group (P<0.05),and the apo A1 level was lower (P<0.05). The TC,Glu,TG and Hcy levels of coronary heart disease group were higher than those in control group (P<0.05),and the apo A1 level was lower than that in control group (P<0.05). The sd-LDL-C level in coronary heart disease group was positively correlated with apo A1,apo B,apo E,TC and LDL-C (r=0.372,0.316,0.248,0.718 and 0.316,P<0.05),and it was negatively correlated with HDL-C(r=-0.218,P<0.05). The sd-LDL-C level in T2DM group was positively correlated with apo A1,apo B,apo E,TC,TG and LDL-C(r=0.243,0.779,0.416,0.616,0.614 and 0.678,P<0.05). The sd-LDL-C level in hypertension group was positively correlated with TC,TG and LDL-C(r=0.623,0.756 and 0.699,P<0.05),and it was negatively correlated with HDL-C(r=-0.355,P<0.05). The sd-LDL-C level in cerebral stroke group was positively correlated with apo A1,apo E and TG(r=0.398,0.117 and 0.271,P<0.05). Conclusions Sd-LDL-C levels in T2DM and hypertension groups are increased,and the level of sd-LDL-C plays a role in cardiovascular and cerebrovascular diseases.
