Effect of apoB polymorphism on plasma lipid levels and cerebral hemorrhage in Changsha Han Chinese / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore the effect of apoB polymorphism on plasma lipid levels and cerebral hemorrhage in (CH) Changsha Han Chinese.@*METHODS@#One hundred thirty CH patients and 100 normal people were involved. C7673T polymorphism of apoprotein B was analyzed by PCR-restriction fragment length polymorphism (PCR-PFLP); and the triglyceride(TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL), and low density lipoprotein-cholesterol(LDL) levels were examined by oxidase method. The serum level of lipoprotein(a) was determined by immunology method.@*RESULTS@#(1) Allele T frequencies of apoB C7673T in CH patients and the control group were 0.108 and 0.040, respectively. Allele T frequencies of apoB C7673T in the CH patients were significantly higher than those in the control group (P< 0.01). (2) In the CH patients, the levels of TC and LDLjC of the T/C gene type were significantly higher than those of the C/C gene type, while the levels of HDLjC of the T/C gene type were significantly lower than those of the C/C gene type (P< 0.05).@*CONCLUSION@#ApoB C7673T polymorphism may be related to cerebral hemorrhage, and the changing blood lipid level may increase the susceptibility of CH.
