【摘要】 目的探讨血清肌红蛋白(Mb)、肌酸激酶(CK)和相关炎性介质在多发伤患者血清中的动态表达及其临床意义。方法将2013年5月至2015年3月在我院急诊重症监护室(EICU)住院治疗的多发伤患者56例作为研究组,并根据入院伤情进一步分为轻度创伤组(n=16)、中度创伤组(n=29)、重度创伤组(n=11),动态观察多发伤患者病情变化情况。根据多器官功能障碍综合征(MODS)评判标准,将56例患者分为MODS组(n=19)和非MODS组(n=37)。分别对各组患者伤后第1、3、7、14 d血清Mb、CK、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)进行检测。同法测定20例健康体检者血清相应指标作为对照。结果与对照组比较,多发伤患者血清Mb、CK、IL-6和TNF-α水平在伤后第1、3、7、14 d均显著升高(P<0.05)。多发伤轻、中、重度创伤组血清Mb、CK、IL-6和TNF-α水平在伤后第3 d升至高峰,随后逐渐下降。其中血清Mb、CK、IL-6和TNF-α水平在第3 d时与同组间不同时段比较,差异有统计学意义(P<0.05)。在伤后第1 d,患者血清Mb、CK、IL-6和TNF-α水平水平在MODS组和非MODS组亦有显著差异(P<0.05)。Mb、IL-6和TNF-α判断MODS的ROC曲线下面积(AUC)分别为0.527~0.817、0.641~0.890、0.197~0.544。结论 Mb、CK、IL-6和TNF-α的动态变化与多发伤患者病情严重程度、变化趋势及预后具有一定相关性。多发伤患者血清Mb、IL-6和TNF-α水平增高对预测继发性MODS有一定价值。更多还原

【Abstract】 Objective To investigate the dynamic expression and clinical significance of myoglobin, creatine kinase and inflammatory mediators in the serum of patients with multiple trauma. Methods From May 2013 to March2015, 56 patients with multiple trauma admitted in EICU were recruited in the study. According to the injury severity, 56 patients were divided into a mild trauma group, a medium trauma group and a severe trauma group. The subjects were further divided into a MODS group and a non-MODS group based on multiple organ dysfunction syndrome（MODS）criteria. Twenty healthy adults undergoing physical examination were recruited as control. Serum myoglobin, creatine kinase, IL-6 and TNF-α levels were measured in the multiple trauma patients(1^st day, 3^rd day, 7^th day and 14 th day) and the controls. Results Compared with the controls, the serum levels of myoglobin, creatine kinase, IL-6 and TNF-α in the patients with multiple trauma increased significantly from 1^st to 14 th day after injury（all P<0.05）. Serum myoglobin,creatine kinase, IL-6 and TNF-α levels on 3^rd day after injury reached the peak, then decreased gradually in the mild,medium, and severe trauma groups, among which the changes of serum myoglobin, creatine kinase, IL-6 and TNF-α levels were significant on 3^rd day compared with other timepoints（all P<0.05）. On 1^st day after injury, serum levels of myoglobin, creatine kinase, IL-6 and TNF-α also differed significantly between the MODS group and non-MODS group（all P<0.05）. The AUCs of myoglobin, IL-6 and TNF-α for predicting MODS were 0.527-0.817, 0.641-0.890, and 0.197-0.544, respectively. Conclusions The dynamic changes of serum myoglobin, creatine kinase, IL-6 and TNF-α in patients with multiple trauma are correlated well with the injury severity and prognosis. Serum myoglobin, IL-6 and TNF-α levels may be good markers to predict secondary MODS in multiple trauma patients.更多还原
