摘要:

目的 初步建立成都地区血脂水平正常的表观健康者小而密低密度脂蛋白胆固醇(sd-LDL-C)的参考区间,并分析sd-LDL-C与其他血脂成分的相关性。方法 选取846名20~69岁血脂水平正常的表观健康者,其中男474名、女372名。按年龄(20~29岁、30~39岁、40~49岁、50~59和60~69岁)和性别(男性、女性)分别分组。采用过氧化物酶法检测血浆sd-LDL-C水平,同时检测总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、载脂蛋白A1(apo A1)、载脂蛋白B(apo B)水平。采用百分位数法建立参考区间。血脂的适宜水平采用中位数(M)[四分位数(P2.5~P97.5)]表示。结果 男性、女性之间血浆sd-LDL-C、TC、TG、HDL-C、LDL-C、apo A1和apo B水平差异均有统计学意义(P<0.05)。男性20~49岁各年龄段血浆sd-LDL-C水平均高于同年龄段女性(P<0.05);50~59和60~69岁男性、女性之间血浆sd-LDL-C水平差异无统计学意义(P>0.05)。不同性别各年龄组之间sd-LDL-C、TC、TG、LDL-C和apo B项目的适宜水平差异均有统计学意义(P<0.05),男性HDL-C、apo A1项目和女性HDL-C项目各年龄组的适宜水平差异均无统计学意义(P>0.05)。20~29岁、30~39岁、40~49岁、50~59和60~69岁男性sd-LDL-C参考区间分别为0.19~0.93、0.29~0.98、0.31~1.01、0.26~0.99、0.30~1.03 mmol/L,女性分别为0.19~0.82、0.23~1.03、0.20~0.96、0.26~1.15、0.23~1.25 mmol/L。sd-LDL-C与TC、TG、 LDL-C、apo B均呈正相关(r值分别为0.601、0.544、0.758、0.757,P<0.05),与HDL-C、apo A1均呈负相关(r值分别为-0.256、-0.123,P<0.05)。结论 初步建立了成都地区表观健康者sd-LDL-C的参考区间。

Abstract:

Objective To establish the reference interval of small and dense low-density lipoprotein cholesterol(sd-LDL-C) in apparently healthy adults in Chengdu,and to analyze the correlation between sd-LDL-C and other blood lipid parameters. Methods A total of 846 apparently healthy adults with normal blood lipids aged 20 to 69 years,including 474 males and 372 females,were enrolled. They were classified according to ages(20-29 years old,30-39 years old,40-49 years old,50-59 years old and 60-69 years old groups) and sex(male and female groups). Plasma sd-LDL-C levels were determined by peroxidase method,and the levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),apolipoprotein A1(apo A1)and apolipoprotein B(apo B) were also determined. The percentile method was used to establish the reference interval. The appropriate levels of blood lipids were indicated by medians(M)(P2.5-P97.5). Results There was statistical significance in plasma sd-LDL-C,TC,TG,HDL-C,LDL-C,apo A1 and apo B levels between male and female groups(P<0.05). Plasma sd-LDL-C levels in males aged from 20 to 49 years were higher than those in females of the same age group(P<0.05). Plasma sd-LDL-C level in males aged 50 to 59 years was higher than that in females(P>0.05). Plasma sd-LDL-C level in males aged 60 to 69 years was lower than that in females(P>0.05). There was statistical significance in the appropriate levels of sd-LDL-C,TC,TG,LDL-C and apo B among age groups(P<0.05),while there was no statistical significance in the appropriate levels of HDL-C and apo A1 in male group and HDL-C in female groups(P>0.05). The reference intervals of sd-LDL-C were 0.19-0.93,0.29-0.98,0.31-1.01,0.26-0.99 and 0.30-1.03 mmol/L for males aged 20 to 29,30 to 39,40 to 49,50 to 59 and 60 to 69 years,respectively,and they were 0.19-0.82,0.23-1.03,0.20-0.96,0.26-1.15 and 0.23-1.25 mmol/L for females,respectively. The sd-LDL-C was positively correlated with TC,TG,LDL-C and apo B(r values were 0.601,0.544,0.758 and 0.757,P<0.05),and it was negatively correlated with HDL-C and apo A1(r values were -0.256 and -0.123,P<0.05). Conclusions The reference interval of sd-LDL-C has been established in Chengdu.
