The analysis of the blood fatty in different genotypes of matrix metalloproteinases in the carotid atherosclerosis patients with essential hypertension / 中国医师进修杂志

ABSTRACT

Objective To investigate the blood fatty levels in different genotypes of matrix metalloproteinases (MMP) and the carotid atherosclerosis (CAS) in patients with essential hypertension (EH).Methods Four hundred and eighty-eight cases of Han and Uygur in patients with EH were selected,and MMP-2-735 C/T and MMP-3-1171 5A/6A polymorphism was measured by polymerase chain reactionrestriction fragment length polymorphism.They were divided into two groupsEH with CAS group (CAS group,293 cases,Han 171 cases,Uygur 122 cases) and EH without CAS group (NS group,195 cases,Han 105 cases,Uygur 90 cases).Blood fatty factors were analyzed according to the different MMP genotypes.Results According to MMP-2 genotypes,in Hart CAS group,the low density lipoprotein cholesterol (LDL-C) levels in MMP-2 CT+TT genotypes were significantly higher than those in CC genotype(P ＜ 0.05),and high density lipoprotein cholesterol levels were significantly lower than those in CC genotype(P ＜ 0.05); In Uygur CAS group,the triglyceride levels in MMP-2 CT+TT genotypes were significantly higher than those in CC genotype(P ＜ 0.05).According to MMP-3 genotypes in Han NS group,the total cholesterol and LDL-C levels in 6A/6A genotype were significantly higher than those in 5A/5A+5A/6A genotypes (P ＜ 0.05).Conclusion The blood fatty levels are different in patients with different MMP genotypes,which may probably influence the CAS.
