BACKGROUND
To investigate the relationship between the HindIII polymorphism and hypertensive intracerebral hemorrhage (HIH) and lipid metabolism.
METHODS
A polymerase chain reaction-restriction fragment length polymorphism assay and the chain termination DNA sequencing method were used to determine the HindIII genotypes of 267 subjects, which included 120 cerebral hemorrhagic patients and 147 controls. The fasting levels of lipids and glucose in the plasma were used to measure the effect of genotype on HIH risk factors.
RESULTS
The frequency of the T allele of the HindIII polymorphism in the HIH group was 90.8%. The frequency of the G allele was 9.2%. In the control group, the frequencies were 82.3% T and 17.7% G, which indicated that the proportion of the G allele in the HIH patient group was significantly lower than in the control group (P<.05). The frequency of GG+GT genotypes in HIH patients (P<.05) and the plasma triglyceride (TG) levels in these patients (P<.05) were also lower than in the control group. The levels of plasma TG, low-density lipoprotein cholesterol, glucose, systolic blood pressure, and diastolic blood pressure in the HIH group were higher than in the controls (P<.05). After controlling for risk factors related to HIH, the HindIII G allele was negatively correlated with the incidence of HIH (odds ratio=.417, 95% confidence interval: .193-.901).
CONCLUSIONS
The HindIII G allele may be a protective factor against the development of HIH among the Han Chinese population.
