摘 要:目的 观察冠心病患者促炎因子白细胞介素(IL)-1β和抑炎因子IL-10的全身水平与病变局部水平的关系。方法 入选慢性稳定性心绞痛(SA)、不稳定性心绞痛/非ST段抬高型心肌梗死(UA/NSTEMI)、ST段抬高型心肌梗死(STEMI)和拟诊冠心病但冠状动脉造影正常者(对照组)各30例。在所有患者(n=120)的主动脉根部(代表全身水平)、冠状动脉疾病患者(n=90)的冠状动脉病变以远和14例STEMI患者的冠状静脉窦取血,采用ELISA法检测IL-1β和IL-10水平,并比较IL-1β和IL-10全身水平和病变局部水平。结果 对照组、SA、UA/NSTEMI和STEMI组全身IL-1B水平分别为lg^-1(0.97±0.42)、lg^-1(0.98±O.43)、lg^-1(1.21±0.42)和lg^-1(1.30±0.43)ng/L,UA/NSTEMI和STEMI组均明显高于对照组(P〈0.05,P〈0.01);IL-10水平分别为lg^-1(0.77±0.29)、lg^-1(0.73±0.45)、lg^-1(0.75±0.35)和1g^-1(1.14±0.36)ng/L,STEMI组IL-10水平高于对照组(P〈0.01)。sA组粥样硬化病变以远IL-1β和IL-10水平分别为lg^-1(0.98±0.41)和lg^-1(0.67±0.47)ng/L,与全身水平比较差异无统计学意义;UA/NSTEMI组粥样硬化病变以远IL-1β和IL-10水平分别为lg^-1(1.22±0.48)和lg^-1(0.89±0.46)ng/L,IL一10血浆浓度高于全身水平(P=0.024),IL-1B水平差异无统计学意义;STEMI组罪犯病变以远IL-1β和IL-10水平分别为lg^-1(1.45±0.45)和lg^-1(1.354-0.31)ng/L,均高于全身水平(P均〈0.01)。左冠状动脉急性闭塞的STEMI患者的全身、冠状动脉内病变以远和冠状静脉窦的IL-1β水平分别为lg^-1(1.47±0.37)、lg^-1(1.65±0.34)和lg^-1(1.53±0.35)ng/L,IL-10水平分别为lg^-1(1.06±0.48)、lg^-1(1.34±0.39)和lg^-1(1.34±0.23)ng/L。冠状静脉�Objective To compare the systemic and local near atherosclerosis lesion levels of proinflammatory factor interleukin-lβ (IL-1β) and anti-inflammatory factor IL-10 in patients with coronary artery disease (CAD). Methods Plasma samples were collected from 30 individuals without angiographical coronary artery stenosis (control group), 90 patients with CAD (stable angina pectoris, SA, n = 30, unstable angina pectoris/non-ST-segment elevation myocardial infarction, UA/NSTEMI, n = 30 and ST- segment elevation myocardial infarction, STEMI, n =30 ) . During diagnostic coronary angiography or interventional procedures, systemic samples were obtained from aorta root in all patients (n = 120), local samples from distal of the coronary lesion in patients with CAD ( n = 90), and samples from coronary sinus of 14 patients with STEMI. IL-1β and IL-10 were determined by ELISA method. Results The result showed systemic levels of IL-I β were lg ^-1 ( 0. 97 ± 0. 4:2 ), lg ^-1 ( 0. 98 ± 0. 43 ), lg ^-1( 1.21 ± 0. 42 ), lg ^-1 ( 1.30 ± 0.43 ) ng/L in the control, SA, UA/NSTEMI and STEMI groups, were significantly higher in UA/NSTEMI and STEMI groups compared with the control group ( P 〈 0. 05, P 〈 0. 01 ) ; systemic IL-10 levels were lg ^-1 ( 0. 77 ±0. 29 ), lg ^-1 ( 0. 73 ± 0. 45 ), lg^-1 ( 0. 75 ±0. 35 ), lg^-1 ( 1.14 ± 0. 36 ) ng/L in the four groups and was significantly higher in STEMI group than the control group (P 〈 0. 01 ). The local concentration of IL-1βand IL-10 were similar as the systemic levels in SA group [lg^-1 (0. 98 ±0.41 ), lg^-1 (0. 67 ±0.47) ng/L], local IL-1β [lg^-1( 1.22 ±0.48) ng/L] was similar while local IL-10 lg^-1 (0. 89 ±0. 46) ng/L] was significantly higher than the systemic levels in UA/NSTEMI group. The local levels of IL-1β and IL-10 [lg ^-1 ( 1.45 ± 0. 45 ), lg ^-1 ( 1.35 ± 0. 31 ) ng/L ] were both significantly higher than the systemic levels in STEMI group ( all P 〈 0. 01 ). T
