摘　　要：目的:检测高原肺水肿患者发生及转归过程中内皮生长因子(VEGF),肿瘤坏死因子-α(TNF-α),白介素-6(IL-6)和一氧化氮(NO)的含量变化,探讨高原肺水肿发生发展可能的病理生理机制。方法:收集10例高原肺水肿患者治疗前和转归后的血清样本,采用酶联免疫法和硝酸还原测定VEGF,TNF-α,IL-6和NO的含量。结果:VEGF在高原肺水肿发病时血清的含量为(167.9±26.5)pg/ml,而转归之后其含量显著降低为(53.1±17.0)pg/ml,(P<0.01);TNF-α在血清中的含量从发病时的(86.2±24.1)pg/ml减少到转归后的(29.2±6.8)pg/ml,(P<0.05),有显著性差异。而IL-6的水平也从发病时的(32.3±16.5)pg/ml变化为转归后的(12.5±8.0)pg/ml,虽然有下降的趋势,但没有统计学差异。而高原肺水肿患者血清中的NO水平从发病时的(33.8±3.3)μmol/L明显的升高到转归后的(74.1±6.2)μmol/L,(P<0.01)。结论:VEGF,TNF-α,IL-6和NO参与了高原肺水肿的发生和转归过程。Objective：To explore the possible pathophysiological process and mechanisms underlying the development and formation of high altitude pulmonary edema（HAPE） by observing the changes in contents of VEGF,TNF-α,IL-6 and NO in serum from the initiated and recovery of HAPE patients.Methods：We studied 10 HAPE patients in a Chinese population.The patients were divided into two groups including HAPE initiate group and the recovery group.Contents of VEGF,TNF-α,IL-6 and NO in serum of the two groups were determined to study the process of HAPE.Results：VEGF levels in the HAPE initiate one and the recovery groups were（167.9±26.5 and 53.1±17.0 pg/ml）,respectively.There was a significant decrease of VEGF content in recovery one compared to the HAPE group.The same results for TNF-α were gained.The levels of TNF-α in recovery group was much lower than that in the HAPE initiate one.They were（29.2±6.8）pg/ml and（86.2±24.1）pg/ml,respectively.The contents of IL-6 in HAPE initiate group and the recovery group were（32.3±16.5）pg/ml and（12.5±8.0）pg/ml,respectively.But no significance existed.The level of NO in HAPE initiate group was（33.8±3.3）μmol/L,and it remarkably increased to（74.1±6.2）μmol/L in recovery one.Conclusion：VEGF,TNF-α,IL-6 and NO participated in the different aspects of the pathophysiological process and might have influence on HAPE.
