Objective To analyze relationship between the gene polymorphism of CYP4F2 and essential hypertension (EH) in China's Han population. Methods 189 EH patients and 187 age-matched controls were used to analysis G20597A polymorphism site of CYP4F2 gene with polymerase chain-restriction fragment length polymorphisms. Results There was no difference of neither genotype nor allele of CYP4F2 (G20597A) between EH and controls through stratified analysis on gender. CYP4F2 gene 20597 G allele carriers had significant association with EH for male in China (81.6% vs 71.3% , P =0.019) , but not with female. After adjustment for cardiovascular risk factors (including smoking, TC, age, genetype, BMI) , the hazard ratio for incident EH in male with CYP4F2 20597GG increased about 2. 689 than that with CYP4F2 20597GA and 20597AA. Conclusion CYP4F2 20597G allele has significant association with male EH, and CYP4F2 20597GG may be an independent predictor of EH for male in china's Han population.

AIM:Mitochondrial DNA (mtDNA) copy number variation (CNV), which reflects the oxidant-induced cell damage, has been observed in a wide range of human diseases .However, whether it correlates with heart failure , which is closely related to oxidative stress, has never been elucidated before .We aimed to systematically investigate the association between leukocyte mtDNA CNV and heart failure risk and prognosis .METHODS: A total of 1 700 hospitalized patients with heart failure and 1 700 age-and gender-matched community population were consecutively enrolled in this observational study , as well as 1 638 ( 96.4%) patients were fol-lowed prospectively for a median of 17 months (12~24 months).The relative mtDNA copy number in leukocyte of peripheral blood or cardiac tissue was measured in triplicate by quantitative real-time PCR method .RESULTS:Patients with heart failure possessed much lower relative mtDNA copy number compared with control subjects (P<0.01), especially for the patients with ischemic etiology (P<0.01).Patients with lower mtDNA copy number exhibited 1.7 times higher risk of heart failure ( P<0.01).Long-term follow-up (median 17 months) showed that decreased mtDNA copy number was significant associated with both increased cardiovascular deaths (P<0.01) and cardiovascular rehospitalization (P<0.01).After adjusted for the conventional risk factors and medications , lower mtDNA copy number were still significantly associated with 50% higher cardiovascular mortality (P <0.05).CONCLUSION:
mtDNA copy number depletion is an independent risk factor for heart failure and predicted higher risk of cardiovascular deaths in patients with heart failure .
