Background Vascular smooth muscle cells （VSMCs） can express heme-oxygenase （HO）, a rate-limiting enzyme in the degradation of heme to bilirubin, ferritin and carbon monoxide （ CO）. VSMC-derived CO can suppress VSMC proliferation and may serve as an antiproliferation factor. The promoter region of HO-1 shows a polymorphism with different （GT）n repeats that has been reported to differently induce gene expression. The objective of this study was to examine the effect of this variation on the occurrence of restenosis after in-stent treatment in patients with coronary artery disease. Methods Candidates who underwent coronary stent implantation were genotyped for the HO-1 promoter polymorphism using polymerase chain reaction （PCR） and automated DNA capillary sequencer. Serum levels of IL-6 and C-reactive protein （CRP） were obtained at baseline, 24 hours and 48 hours after stenting. The primary end point for the study was angiographic evidence of in-stent restenosis at 6 months. All parameters for evaluation of restenosis were analysed by quantitatve computer-assisted angiographic analysis （QCA）. Results One hundred and eighty-seven patients who underwent coronary stent implantation were studied of whom 27.8% showed 〉150% restenosis after 6 months. The distribution of （GT）n repeats of all patients in the promoter region of HO-1 genotype ranged from 22 to 42, with （GT） 25 and （GT） 32 being the two most common alleles. The allelic repeats were divided into the short class （S） with 29 （ GT）., the middle class （M） with 30- 37 （GT）n and the long class （L） with 38 （GT）n. There was no significant difference in the restenosis between the genotype groups or between post operation levels of inflammation markers, but carriers of the S allele （ n = 120） had 33.3% lower baseline IL-6 compared with non-S carriers （n =67, P =0. 0008）. Conclusions Although no association was observed between the HO-1 promoter polymorphism and coronary in-stent restenosis following the stent procedure, the

目的:观察I型血红素氧化酶(HO-1)基因启动子GT重复长短对冠状动脉支架置入术后再狭窄的影响。方法:187例行冠状动脉支架置入术者,6个月时随访再狭窄情况。PCR和DNA测序仪确定HO-1启动子GT重复次数。高敏法测术前及术后24h、48h血浆白介素-6(IL-6)和C反应蛋白(CRP)值。结果:各基因型间术后IL-6和CRP水平及再狭窄发生率无差异,携较短GT者术前血浆IL-6水平比非短GT序列携带者低约33．3％(P=0．0008)。结论:HO-1基因多态性不影响支架置入术后炎症介质水平及再狭窄,但可能影响动脉粥样硬化形成的炎症过程。
