摘  要:目的探讨同步测定血清肌酸激酶同工酶(CK-MB)与肌酸激酶(CK)比值(CK-MB/CK)及心肌肌钙蛋白I(cTnI)在急性有机磷农药中毒(AOPP)中的变化及其在病情判断、评估中的临床价值和意义。方法对868例无心、肺、脑、肾、肌肉及其他结缔组织疾病史的AOPP患者于中毒后2、12、24、48、96、120h抽取空腹静脉血4ml同步测定CK、CK—MB及cTnI,计算出CK-MB/CK。其中轻度中毒279例(轻度组),中度中毒289例(中度组),重度中毒300例(重度组),合并发生中毒中间型综合征(IMS)208例(IMS组),未发生IMS660例(非IMS组)。并与同期288例健康查体者(对照组)比较。结果(1)中毒后2-12、13-24、25—120h轻度组、中度组、重度组CK、CK-MB、cTnI显著高于对照组,CK-MB/CK显著低于对照组,差异均有统计学意义(P〈0.01);轻度组、中度组、重度组CK、CK-MB、cTnI、CK-MB/CK组间两两比较差异均有统计学意义(P〈0.01或〈0.05)。IMS组中毒后2—120hCK、CK-MB、cTnI显著高于非IMS组,CK-MB/CK显著低于非IMS组,差异均有统计学意义(P〈0.05或〈0.01)。IMS组心脏猝死发生率23.08%(48/208),多器官功能障碍综合征(MODS)发生率37.50%(78/208);非IMS组分别为4.24%(28/660)、9.85%(65/660)。两组心脏猝死和MODS发生率比较差异均有统计学意义(P〈0.01)。(2)对IMS组及非IMS组建立以cTnI(X1)、CK(X2)及CK—MB/CK(X,)为自变量的判别分析方程式:Y=-0.0014X。+0.0225X2+65.2376X3,F=21.4911,P〈0.01。判别临界值Y0=2.8124。若Y〈2.8124属IMS组,Y≥2.8124属非IMS组。其中各指标的贡献率X1为34.5%,X:为25.4%,X,为40.1%,回代符合率为91.26%。结论CK-MB/CK变化与AOPP程度呈负相关,cTnI与AOPP程度呈正相关。CK-MB/CK变化、cTnI可用于协助AOPP临床分级、病Objective To investigate the changes of serum creatine kinase isoenzyme (CK-MB) and creatine kinase (CK) ratio (CK-MB/CK) and cardiac troponin I (cTnI) simultaneously in patients with acute organophosphorus pesticide poisoning (AOPP) and the clinical value in disease condition judgment. Methods Eight hundred and sixty-eight AOPP patients without disease history of heart,lung,brain, kidney,muscle and other connective tissue were extracted 4 ml of fasting venous blood to determine CK, CK-MB and cTnI simultaneously at 2,12,24,48,96 and 120 hours after poisoning,and the CK-MB/CK was calculated. There were 279 mild poisoning cases (mild poisoning group),289 moderate poisoning cases (moderate poisoning group) and 300 severe poisoning group (severe poisoning group) ; and 208 cases with intermediate myasthenia syndrome (IMS) (IMS group) and 660 cases without IMS (non-IMS group). The result was compared with 288 healthy people (control group) in the same period. Results ( 1 ) The CK, CK-MB and cTnI of mild,moderate and severe poisoning groups between 2 to 12 h, 13 to 24 h,25 to 120 h after poisoning were significantly higher than those in control group, CK-MB/CK was obviously lower (P 〈 0.01 ). The CK, CK-MB, cTnI and CK-MB/CK had significant differences between each two of mild, moderate and severe poisoning groups (P 〈 0.01 or 〈 0.05 ). The CK, CK-MB and cTnI of IMS group in 2 to120 h after poisoning were significantly higher than those in non-IMS group, and CK-MB/CK was lower (P 〈 0.05 or 〈 0.01 ). In IMS group,the rates of sudden cardiac death (SCD) and multiple organ dysfunction syndrome (MODS) were 23.08% (48/208), 37.50% (78/208) respectively, while 4.24% (28/660), 9.85% (65/660) in non-IMS group. The incidence of SCD and MODS of two groups had statistical significance (P 〈 0.01 ). (2) According to IMS and non-IMS group,discriminant equation with independent variables of cTnI (X1),CK (X2) and CK-MB/CK
