Abstract:
Objective To investigate the relationship between apolipoprotein E (APOE) genotype and onset of hypertensive intracerebral hemorrhage (HICH). Methods One hundred and twenty-eight patients with HICH,admitted to our hospital from September 2007 to December 2010,and 84 healthy controls clinically flee from neurology disease were chosen in our study.A POE genotype was determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP); the distribution ofAPOE genotype and allele fiequency between the 2 groups were compared; the age of onset,gender,blood pressure,blood fat,bleeding part and size of haematoma in patients with different APOE genotype were further studied. Results The subjects with smoking hobby,diabetes history and higher concentrations of TC and LDL-C in the HICH group were obviously more than those in the control group (P＜0.05).As compared with those in the controls,the distributions of the APOEε3/4 and APOEε4 in the HICH group were significantly higher, and the distributions of the APOEε3/3 and APOEε3 in the HICH group were significantly lower (P＜0.05). The APOEε3/4 and APOEε4 carriers enjoyed higher percentages of onset age less than 45 years and superficial haematoma than A POEε3/3 and the A POEε3 carriers. The onset systolic blood pressure in APOEε3/4 and APOEε4 carriers was obviously lower than that in A POEε3/3 and A POEε3 carriers (P＜0.05). The plasma concentrations of LDL-C and TC in APOEε3/4 and APOEε4 carriers was significantly higher than those in APOEε3/3 and APOEε3 carriers (P＜0.05). Conclusion The APOE genotype influences the onset of HICH, and its influence factors included onset age, blood pressure,blood fat and bleeding part,which may concern with the cerebral artherosclerosis or amyloidosis.
