摘要: 目的 观察高晶体-高胶体渗透压混合液(HHS)对缺氧/氧再灌损伤的人脐静脉内皮细胞(HUVEC)容积和存活率的影响。方法 取HUVEC株ECV-304,分为对照组和实验组。两组细胞先置于缺氧(95 %氮气,5 %CO2)环境中8 h,然后将实验组细胞置于HHS 15 min,再在常氧状态下(95 %空气,5 %CO2)培养16 h 。对照组细胞直接置于常氧状态下(95 %空气,5 %CO2)培养16 h 。两组细胞分别于实验前、实验开始后15 、60 min 和8 、8.25 、16 及24 h 测其细胞容积和存活率。结果 对照组细胞在缺氧60 min 后及氧再灌过程中明显肿胀(P<0.05或0.01),细胞存活率进行性降低(P<0.05或0.01)。实验组细胞经HHS 处理后细胞容积较同一时段的对照组细胞容积明显缩小(P<0.01),存活率尽管仍低于实验前(P<0.01),但明显高于同一时段的对照组(P<0.05)。结论 HHS 具有刺激内皮细胞产生延迟性调节性容积减少,保持容积稳定的作用,能在一定程度上降低内皮细胞的死亡率,保护缺氧/氧再灌损伤的内皮细胞。

Abstract: AIM: To investigate the effect of hypertonic-hyperoncotic solution(HHS)on cell volume and survival rate in human umbilical vein endothelial cells(HUVEC)suffering from hypoxia/reperfusion.METHODS: HUVEC of ECV-304 were selected and randomly divided into control grouPand experimental group.Cells in two groups were cultured in hypoxia environment(95 %nitrogen,and 5 % carbon dioxide)for 8 h,then in normal environment(95 % air,and 5 % carbon dioxide)for 16 h in control group,and in HHS for 15 min in experimental group.The cell volume and the survival rate were detected before experiment,15 min,60 min,8,8.25,16,and 24 h after experiment in two groups.RESULTS: In control group,cells became significantly inflated and the survival rate decreased in hypoxiaPeriod afterlasting 60 min and hypoxia/reperfusionPeriod(P<0.05 orP<0.01).In experimental group,cells became deflated significantly compared with control grouPat the samePeriod(P<0.01).The survival rate decreased,but significantly higher than that in control grouPat the samePeriod(P<0.05).CONCLUSION: HHS can delay RVD,keePcell volume steady,and decrease cell mortality suffering from hypoxia/reperfusion.
