摘要:

目的 探讨武汉地区表观健康人群脂蛋白相关磷脂酶A2(Lp-PLA2)水平的分布。方法 选取表观健康者1 503名,检测其血清淀粉样蛋白A(SAA)、Lp-PLA2、同型半胱氨酸(Hcy)水平。收集所有对象的一般资料,包括年龄、性别及总胆红素(TB)、直接胆红素(DBil)、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、碱性磷酸酶(ALP)、γ-谷氨酰基转移酶(GGT)、血尿素氮(BUN)、肌酐(Cr)、尿酸(UA)、胱抑素C(Cys C)、血糖(Glu)、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、载脂蛋白A(apo A)、载脂蛋白B(apo B)、脂蛋白(a)[Lp(a)]等常规生化指标检测结果。采用Spearman相关分析评价Lp-PLA2与其他项目的相关性。结果 以Lp-PLA2≥200 ng/mL为升高(阳性)标准,男性血清Lp-PLA2水平及阳性率均高于女性(P<0.001)。表观健康人群总体、男性及女性中,≥61岁组的Lp-PLA2阳性率均高于41~60岁组及≤40岁组,且41~60岁组血清Lp-PLA2水平最高。Lp-PLA2升高组年龄、SAA、ALT、AST、ALP、GGT、BUN、UA、Cr、Cys C、Glu、TG、apo B、Hcy均高于Lp-PLA2正常组(P<0.05),TB、DBil、HDL-C、apo A均低于Lp-PLA2正常组(P<0.05),2个组之间TC、LDL-C、Lp(a)差异均无统计学意义(P>0.05)。Lp-PLA2高度升高(>400 ng/mL)组LP-PLA2、SAA、GGT、Glu水平显著高于中度升高(301~400 ng/mL)组及轻度升高(200~300 ng/mL)组(P<0.05),其他指标3个组之间差异均无统计学意义(P>0.05)。Spearman相关分析结果显示,Lp-PLA2与SAA、GGT呈正相关(r值分别为0.422、0.162,P值分别为<0.001、0.001),与其他指标均无相关性(P>0.05)。结论 武汉地区表观健康人群Lp-PLA2水平较高,因此有必要在表观健康人群中开展Lp-PLA2筛查。

Abstract:

Objective To investigate the distribution of lipoprotein-associated phospholipase A2(Lp-PLA2) among apparently healthy population in Wuhan. Methods Totally,1 503 apparently healthy subjects were enrolled. The levels of serum amyloid A(SAA),Lp-PLA2 and homocysteine(Hcy) were determined. The data fo sex and age and the determination result data of total bilirubin (TB),direct bilirubin (DBil),alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),gamma-glutamyltransferase (GGT),blood urea nitrogen (BUN),creatinine (Cr),uric acid (UA),cystatin C (Cys C),glucose (Glu),total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),apolipoprotein A (apo A),apolipoprotein B (apo B) and lipoprotein(a)[Lp(a)] were collected. The correlation between Lp-PLA2 and the other indicators was analyzed by Spearman correlation. Results Lp-PLA2 ≥200 ng/mL was used as increasing(positive). The Lp-PLA2 level and positive rate of males were higher than those of females(P<0.001). The positive rate of Lp-PLA2 in ≥61-year-old group was higher than those in 41-60-year-old group and ≤40-year-old group,and serum Lp-PLA2 level was the highest in 41-60-year-old group. In increased Lp-PLA2 group,the age,SAA,ALT,AST,ALP,GGT,BUN,UA,Cr,Cys C,Glu,TG,apo B and Hcy were higher than those in normal Lp-PLA2 group(P<0.05). TB,DBil,HDL-C and apo A were lower than those in normal Lp-PLA2 group(P<0.05). There was no statistical significance in TC,LDL-C and Lp(a) between the 2 groups(P>0.05). The levels of Lp-PLA2,SAA,GGT and Glu in Lp-PLA2 highly increased(>400 ng/mL) group were higher than those in Lp-PLA2 moderately increased(301-400 ng/mL) and slightly increased(200-300 ng/mL) groups(P<0.05). There was no statistical significance for the other indicators among the 3 groups(P>0.05). Spearman correlation analysis showed that Lp-PLA2 was positively correlated with SAA and GGT(r=0.422 and 0.162,P<0.001 and P=0.001,respectively),and it had no correlation with the other indicators(P>0.05). Conclusions Lp-PLA2 is high among apparently healthy population in Wuhan. Lp-PLA2 screening is necessary in apparently healthy population.
