title: [Apolipoportein E polymorphism, serum lipids and apolipoproteins of 362 Han national subjects in Chengdu area].
abstract: This investigation was conducted to observe the frequency distribution of apoE phenotypes and alleles and to explore the relationship between apoE polymorphism and plasma lipids or apolipoproteins in Chinese population. ApoE phenotypes were assayed by isoelectric focusing and immunoblotting with serum. Serum lipids and apoA I, B100, C II, C III, E were determined in a random subset of 362 subjects including 268 males and 94 females with a mean age of 43.7 +/- 12.3 yrs from a population of Han Nationality in Chengdu area. The results showed that the frequencies of apoE phenotypes and alleles were: E3/3 72.93%, E2/3 12.98%, E3/4 11.33%, E2/4 1.38%, E4/4 1.38%, E2/2 0.00%; epsilon 3 0.8508, epsilon 2 0.0718, epsilon 4 0.0774. The results also showed that the apo E2(E2/3 + E2/2) group had lower levels of serum TC and apoB100 (P < 0.05) and a higher level of serum apoE (P < 0.001) when compared with the apoE3(E3/3) or apoE4(E3/4 + E4/4) group. No significant difference was observed in TG, apoA I, apoC II, and apoC III levels among the apoE2, E3 and E4 groups (P > 0.05).
