[Effect of apoB polymorphism on plasma lipid levels and cerebral hemorrhage in Changsha Han Chinese].Zhong Nan Da Xue Xue Bao Yi Xue Ban. 2008 Jun; 33(6):494-9.ZN
To explore the effect of apoB polymorphism on plasma lipid levels and cerebral hemorrhage in (CH) Changsha Han Chinese.
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.
(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).
ApoB C7673T polymorphism may be related to cerebral hemorrhage, and the changing blood lipid level may increase the susceptibility of CH.
