目的:探讨肝硬化上消化道大出血患者体内脂质过氧化状态的变化及丹参注射液对其的影响.方法:肝硬化上消化道大出血患者91例,随机分为丹参注射液治组(n=36)和传统治疗组(n=55).分别测定患者血中超氧化物岐化酶(SOD)活性和过氧化脂质(LPO...目的:探讨肝硬化上消化道大出血患者体内脂质过氧化状态的变化及丹参注射液对其的影响.方法:肝硬化上消化道大出血患者91例,随机分为丹参注射液治组(n=36)和传统治疗组(n=55).分别测定患者血中超氧化物岐化酶(SOD)活性和过氧化脂质(LPO)含量.结果:传统治疗组患者血中LPO含量在出血后明显增加,72h左右达最高峰(11.0±4.1 nmol/L),较出血前或12h内(7.8±3.3 nmol/L)明显升高(P<0.01),1wk后开始下降,4wk后可不同程度恢复.而经丹参注射液治疗的患者血中LPO含量亦于72h左右达最高峰,但变化幅度较小(9.9±4.6nmol/L vs 7.8±3.1nmol/L,P<0.05),恢复较快.两组SOD活性变化与LPO含量变化相反,72h降至最小值(传统治疗组:0.87±0.2 nkat/L vs 1.3±0.2 nkat/L,P<0.01;丹参注射液治组:0.9±0.3 nkat/L vs 1.4±0.2 nkat/L,P<0.01),4 wk后可不同程度恢复.丹参注射液治疗组患者的预后明显优于传统治疗组(P<0.01),且Child-Pugh B级者优于C级(P<0.05).结论:丹参注射液可提高机体的抗氧化能力,改善肝硬化上消化道大出血患者的预后.展开更多
