生脉注射液对心肺复苏中肿瘤坏死因子-α、白细胞介素-8调控的临床研究

目的 将生脉注射液用于心肺复苏早期,探讨其通过调控细胞因子、非特异性抗炎、减轻缺血再灌注损伤的作用机制.方法40例均为心脏停搏后经心肺复苏心搏恢复≥24 h,需要进一步生命支持的患者,随机分为生脉组和对照组.2组患者在常规心肺复苏治疗基础上,生脉组于心肺复苏早期加用生脉注射液.动态观察比较生脉组与对照组复苏前和复苏后1、2、6、12、24h血清肿瘤坏死因子-α(TNF-α)和白细胞介素-8(IL-8)指标的变化.结果 心肺复苏后2组患者血清TNF-α和IL-8水平较正常升高,且生脉组复苏后1、2、6、12、24h血清TNF-α和IL-8水平低于对照组,差异均有统计学意义(均P＜0.05).结论 生脉注射液可通过调控细胞因子,拮抗全身炎症反应而减轻缺血再灌注损伤.

Clinical study of shengmai injection on the regulation of TNF-αand IL-8 during cardiopulmonary resuscitation

Objective To explore the mechanism of shengmai injection on relieving ischemia reperfusion injury and antagonizing systemic inflammatory response syndrome by regulating cytokines when it was applied at the early stage of cardiopulmonary resuscitation(CPR).Methods 40 cases suffering from cardiac arrest and had their heart beat recovered through CPR for more than 24 hours were randomly divided into SMI group and control group(20 cases for each).The patients in the two groups were treated with common therapeutics based on the CPR,but the patients in SMI group were intravenously dropped with SMI in the early period of PLS phase,then the changes of serum concentration of TNF-α and IL-81h,2h,6h,12h and24h after CPR in the two groups was compared.Results The concentrations of serum TNF-α and IL-8 stepped up gradually after resuscitation and the levels of TNF-αand IL-8 in SMI group were lower than that of the control group at 1h,2h,6h,12h and 24h after resuscitation(P＜0.05).Conclusion SMI functions to relieve ischemia reperfusion injury by regulating cytokines and antagonizing systemic inflammatory response syndrome.
