用放免的方法测定了５０例脑血管病（ＣＶＤ）患者血清脂蛋白（α）［Ｌｐ（α）］浓度，对比分析了患者Ｌｐ（α）、甘油三脂（ＴＧ）、总胆固醇（ＴＣ）、高密度脂蛋白胆固醇（ＨＤＬ－Ｃ）、低密度脂蛋白胆固醇（ＬＤＬ－Ｃ）、脱脂蛋白Ａ－Ｉ（ａｐｏＡ－Ｉ）、ａｐｏＢ１００的浓度及变化，分析了Ｌｐ（α）浓度与ＴＧ、ＴＣ和脱脂蛋白的相关性。结果：ＣＶＤ患者血清Ｌｐ（α）浓度（０．２２４±０．０４ｇ／Ｌ），显著高于对照组（０．１１４±０．０３ｇ／Ｌ），ＴＧ、ＴＣ和ＬＤＬ－Ｃ明显升高，ＨＤＬ－Ｃ／ＬＤＬ－Ｃ和ａｐｏＡ－Ｉ／ａｐｏＢ１００比值明显下降。Ｌｐ（α）和ＬＤＬ－Ｃ（ｒ＝０．４５９，Ｐ＜０．０１）、ＴＣ（ｒ＝０．３５６，Ｐ＜０．０２）呈正相关；与ａｐｏＡ－Ｉ／ａｐｏＢ１００比值（ｒ＝－０．４２３，Ｐ＜０．０１）呈负相关。而与ＴＧ、ＨＤＬ－Ｃ、ａｐｏＢ、ａｐｏＡ－Ｉ呈明显相关关系。作者认为Ｌｐ（α）是目前脂代谢指标中最好的ＣＶＤ危险因素的判定指标。
The levels of serum lipoprotein (α) [Lp (α)] in 50 patients with cerebrovascular disease (CVD) were determined by radioimmunoassay. The levels of Lp, TG, (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A-I (apoA-I) Correlation between TC and lipoprotein. Results: The serum concentration of Lp (0.224 ± 0.04g / L) in CVD patients was significantly higher than that in the control group (0.114 ± 0.03g / L), TG, TC and LDL-C were significantly increased HDL-C / LDL-C and apoA-I / apoB100 ratio decreased significantly. Lp (α) was positively correlated with LDL-C (r = 0.459, P <0.01) 0.423, P <0.01). But with TG, HDL-C, apoB, apoA-I was significantly correlated. The authors believe that Lp (α) is the best indicator of CVD risk indicators of lipid metabolism indicators.
