Ⅳ型高脂血症患者血清HDL亚类组成的初步研究

采用双向电泳－免疫印迹检测法，分析了２４例正常人及２４例Ⅳ型高脂血症患者血清ＨＤＬ亚类的相对百分含量。结果显示，与正常人比较，Ⅳ型高脂血症患者血清中小颗粒的前β－ＨＤＬ和ＨＤＬ３ａ含量显著增加（Ｐ值分别〈０．００１和〈０．０５），而成熟的ＨＤＬ２ｂ含量显著减少（Ｐ〈０．００１）。患者血清ＴＧ浓度与前β１－ＨＤＬ及ＨＤＬ３ａ水平呈正相关（相关系数分别为０．５８２和０．６９２），而与ＨＤＬ２ｂ及ＨＤＬ

Study on the contents of serum HDL subclasses in type N hyperlipidemics]

Contents of serum HDL subclasses in normolipidemics (n = 24) and type IV hyperlipidemics (n = 24) were determined using two-dimensional gel electrophoresis associated with immunodetection method. The results showed that the contents of pre-beta 1 HDL (P < 0.001) and HDL3a (P < 0.05) increased significantly and that of HDL2b (P < 0.001) decreased significantly in hyperlipidemics, compared with normolipidemics. Serum TG concentrations of hyperlipidemics showed positive correlation with pre-beta 1 HDL (r = 0.582) and HDL3a (r = 0.692) and negative correlation with HDL2b (r = -0.506) and HDL2a (r = -0.552). These results indicated that the maturation of HDL could be abnormal in type IV hyperlipidemics.
