摘要 目的探讨血尿酸在不同类型冠心病发生中的作用机制。方法88例住院患者分为对照纽、稳定型心绞痛(SA)组和急性冠状动脉综合征(ACS)组,分别测定其血尿酸、血小板α-颗粒膜蛋白(GMP-140)、血管性假性血友病因子(vWF)、纤溶酶原激活物抑制物-1(PAI-1)、血栓素B2(TXB2)、C-反应蛋白(CRP)。结果(1)①UA、CRP:ACS组[(392.10±68.57)μmol/L、(42.2±39.4)mg/L]和SA组[(370.50±58.80)μmo]/L、(18.9±17.1)mg/L]均高于对照组[(286.00±65.31)μmol/L、(2.5±0.7)mg/L,P均〈0.05];UA在ACS组、SA组差异无统计学意义(P〉0.05),ACS组CRP高于SA组(P〈0.05);②vWF、TXB2:ACS组[(1.65±0.48)%、(19.73±18.66)μg/L]和SA组[(1.35±0.49)%、(11.18±10.71)μg/1.]均高于对照组[(1.07±0.26)%、(6.46±5.41)ng/LP均〈0.05],ACS组高于SA组(P均〈0.05);③GMP-140、PAI-1:ACS组[(13.04±0.99)μg/L、(65.65±14.76)μg/g和SA组[(12.55±0.74)μg/L、(62.69±12.24)μg/L]均高于对照组[(12.32±0.29)μg/L、(50.78±13.88)μg/L,P均〈0.05],ACS组与SA组间差异无统计学意义(P均〉0.05)。④ACS组血尿酸升高者与血尿酸正常者CRP[(71.3±18.9)、(20.70±17.9)mg/L]、vWF[(1.08±0.52)%、(0.84±0.54)%]、GMP-140[(13.57±1.11)、(13.23±1.07)μg/L]、TXB2[(57.26±47.84)、(26.70±23.83)μg/L]、PAI-1[(72.12±9.23)、(61.30±12.07)μg/L]差异均有统计学意义(t值分别为7.394、0.008、0.227、7.605、0.421,P均〈0.05),SA组血尿酸升高者与血尿酸正常者CRP[(31.1±18.9)、(10.9±10.1)mg/L]、TXB2[(21.54±3.90)、(5.02±4.93)μg/L]差异均有统计学意义(t值分别为0.494、8.669,P均〈0.05)。(2)Logistic逐步回归分析:与急性冠状动脉综合征相关的因素有UA、CRP、PAI-1、PT、TG(OR值分别为1.046、7.615、1.301、0.300和2.243,P均〈0.05)。结论血尿酸升高是影响冠心病发生、发展的重要危险因素。血尿酸升高可能通过损害血管内皮功能、激活血小板、影响凝血和纤溶功能、引发炎症反应参与不同类型冠心病的发生与发展。 Objective To detect the mechanism of serum uric acid (UA) in different types of coronary heart disease (CHD). Methods 88 patients were divided into three groups:the control group, stable angina (SA) group and acute coronary syndrom (ACS) group. The levels of UA, alpha-granule membrane protein 140 ( GMP- 140) ,von Willebrand factor( vWF), plasminogen activator inhabitor type-1 ( PAI-1 ), Thromboxane B2 ( TXB2 ) and C-reacting protein(CRP) were measured. Results (1)UA and CRP in ACS group were higher than that in SA group and control group [ ( 392.1 ± 68.57 ) μmoL/L and (42.2 ±39.4 ) mg/L vs ( 370.50±58.80 ) μmol/L and ( 18.9± 17.1 ) mg/L vs ( 286. 00 ± 65.31 ) μmol/L and ( 2.5 + 0. 7 )mg/L, P 〈 0. 05 ) ]. For UA, there was no difference between ACS and SA group(P 〉0.05) ; CRP was higher in ACS group than in SA group (P 〈0.05). (2) vWF and TXB2 were higher in ACS[ (1.65 +0.48)% ,(19.73 + 18.66)ng/L] and SA group[ (1.35 +0.49)% ,(11.18 + 10.71 ) ng/L ] than in control group [ ( 1.07± 0.26 ) %, ( 6.46± 5.41 ) ng/L , P 〈 0.05 ], and those were higher in ACS group than in SA group (P 〈0.05). (3)GMP-140 and PAI-1 were higher in ACS[ (13.04 ±0.99) μg/L and (65.65±14.76) μg/L] and SA group[ ( 12.55 ±0.74) μg/L and (62.69 ± 12.24) μg/L] than in control group [ (12.32 ±0.29)μg/L, (50.78 + 13.88)μg/L,P 〈0.05 ]. There were no differences between ACS and SA group (P 〉0.05). (3)Comparing hyperurieemia group and non- hyperuricemia group in CHD patients:the CRP(71.3 ± 18.9 ) mg/L, vWF ( 1.08 ± 0.52 ) %, GMP-140 ( 13.57 ±1.11 )μg/L, TXB2 ( 57.26± 47.84) ng/L, PAI-1 (72.12 ± 9.23 ) μg/L in ACS group possessing hyperuricemia were higher than non-hyperuricemia group [ CRP ( 20.7 ±17.9 ) mg/L, vWF(0. 84 ± 0.54 ) %, GMP-140 ( 13.23 ±1.07 ) μg/L, TXB2 ( 26.70± 23.83 ) ng/L, PAI-1 ( 61.30± 12.07)μg/L ] (t =7. 394,0.008,0. 227,7. 605,0. 421 ,P 〈 0.05 ) ; CRP( 31.1 ± 18.9 ) mg/L and TXB2 (21.54 ± 3.90) μg/L in SA group possessing hyperuricemia group were higher than non-hyperuricemia groupE ( 10.9 ± 10. 1 ) mg/L and ( 5.02 ± 4.93 ) ng/L, t = 0.494±8. 669, P 〈 0.05 ]. Logistic stepwise regression analysis indicated that the related factors with ACS were UA (OR = 1. 046), CRP( OR = 7. 615), PAI-1 (OR = 1. 301 ) , PT( OR = 0. 300) and TG( OR = 2.243 ) (P 〈 0. 05 ). Conclusions UA is an important risk factor in CHD patients. UA can induce different types of CHD by damaging blood vessel endothelium function, activating platelet, changing coagulation and causing inflammatory.
