摘要(Abstract):
目的分析L-精氨酸治疗慢性阻塞性肺疾病(COPD)的临床疗效,探讨其作用机制。方法选取2012年6月—2014年6月顺德区乐从医院收治的COPD患者60例,随机分为对照组和观察组,每组30例。对照组患者进行常规治疗,观察组患者在常规治疗基础上给予L-精氨酸治疗。比较两组患者治疗前后肺动脉压及血清白介素8(IL-8)、C反应蛋白(CRP)、一氧化氮(NO)水平。结果治疗前两组患者肺动脉压比较,差异无统计学意义(P>0.05);治疗后观察组患者肺动脉压低于对照组(P<0.05);治疗后两组患者肺动脉压均低于治疗前(P<0.05)。治疗前两组患者血清IL-8、CRP、NO水平比较,差异无统计学意义(P>0.05);治疗后观察组患者血清IL-8、CRP水平低于对照组,血清NO水平高于对照组(P<0.05)。治疗后观察组患者血清IL-8、CRP水平低于治疗前,而血清NO水平高于治疗前(P<0.05)。结论 L-精氨酸可有效降低COPD患者肺动脉压,其作用机制可能是提高患者体内NO含量、减轻炎性反应。
