摘要
Objective To explore the relationship between polymorphisms of XbaI and MspI loci of apolipoprotein B （ApoB） gene and -75 bp,＋83 bp loci of apolipoprotein AI （ApoAI） gene and coronary heart disease （CHD） in Kazaks of Xinjiang Uyghur Autonomous Region,China.Methods These loci were analyzed by PCR-restriction fragment length polymorphism （PCR-PFLP）.Two hundred and five patients with CHD and two hundred and thirty six controls were involved.Results There were significant distinctions among low-density lipoprotein cholesterol （LDL-C）,triglyceride （TG） and the ApoAI/ApoB ratio between the two groups,but no significant distinction among the polymorphism frequencies of the four sites between the two groups.The polymorphism coalition frequency of X-/Ms＋＋/M1＋-/M2＋＋ （named Coalition 11） was significantly higher in CHD compared to the control group （14.6％ vs.7.2％,P ＜ 0.05）.The level of total cholesterol （TC） in Coalition 1 1 was significantly higher and the level of the ApoAI/ApoB ratio in Coalition 11 was significantly lower than Coalition 1～10 in CHD patients.The level of the ApoAI/ApoB ratio of Coalition 11 was significantly lower than the Coalition 1～10 in control group.The levels of ApoAI/ApoB ratio of Coalition 3 were significantly higher compared to Coalition 11 in the two groups,respectively.The level of LDL-C of Coalition 3 was significantly lower than in the Coalition 11 in control group.The level of TC of Coalition 5 was significantly higher than Coalition 3 in the CHD group.The level of the ApoAI/ApoB ratio of Coalition 5 was significantly lower than in Coalition 3 or Coalition 1～10 of the two groups,respectively.The level of LDL-C of Coalition 5 was significantly higher than in Coalition 3 in control group.The ratio of ApoAI/ApoB was negatively related to TC,LDL-C and was positively related to HDL-C,both in CHD and control groups.Conclusion Coalition 11 of the 4 loci polymorphisms of the ApoB and ApoAI genes was correlated with CHD in Kazaks,and perhap
