ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between C7673T polymorphism of apolipoprotein B (apoB) and cerebral hemorrhage with family history (CHFH) in Chinese Han in Changsha, Hunan province.</p><p><b>METHODS</b>Fifteen families of CHFH and 93 sporadic cerebral hemorrhage patients and 100 normal controls were collected. The C7673T polymorphism of apoB was analyzed by PCR-restriction fragment length polymorphism and direct DNA sequencing. The triglyceride(TG), total cholesterol(TC), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol(LDL-C) levels were examined by oxidase method. The serum level of lipoprotein (a) was determined by immune method.</p><p><b>RESULTS</b>(1)The allele T frequencies of apoB C7673T polymorphism in cerebral hemorrhage patients with family history, first-degree relatives, second-degree relatives, third-degree relatives, the sporadic cerebral hemorrhage patients and the control group were 0.176, 0.136, 0.058, 0.048, 0.081 and 0.040, respectively. (2) The allele T frequencies of apoB C7673T polymorphism in CHFH patients and their first-degree relatives were significantly higher than that of the control group (P< 0.01, P< 0.01), while there was no significant difference among second-degree relatives, third-degree relatives and control group (P> 0.05). And the allele T frequency of apoB C7673T in CHFH patients was significantly higher than that of sporadic cerebral hemorrhage patients (P< 0.05). (3)In CHFH patients and sporadic cerebral hemorrhage group, the levels of TC and LDL-C of the TC genotype were significantly higher than those of the CC genotype, while the level of HDL-C in the TC genotype was significantly lower than that of the CC geneotype (P< 0.05).</p><p><b>CONCLUSION</b>(1)The allele T of apoB C7673T polymorphism may be related to cerebral hemorrhage with family history. (2) The allele T of apoB C7673T polymorphism may increase the susceptibility of cerebral hemorrhage by changing blood lipid levels.</p>
