摘要: 目的 · 建立稳定的大鼠体外肺灌注(ex vivo lung perfusion, EVLP)模型,并且与传统的冷保存方法进行保存效果的对比。
方法 · 对 8 只 SD 大鼠进行 EVLP 转流 4 h,对另外 8 只进行传统冷保存 3 h+ EVLP 1h。比较 2 组肺生理指标、湿干比、伊文思蓝染
色浓度的差异。结果 · EVLP 组的肺湿干比值显著低于传统冷保存组(5.08±0.88 vs 6.09±0.48, P=0.012),氧合指数显著高于传统冷
保存组 [(337.9±35.5)mmHg vs(300.5±21.6)mmHg,P=0.023],伊文思蓝浓度显著低于传统冷保存组 [(36.5±20.3)μg/mL vs
(65.0±29.9)μg/mL,P=0.043]。结论 · EVLP 作为传统冷保存法的一种有效替代方法,能够较好地延缓肺部损伤。

Abstract:

Objective · To establish stable rat ex vivo lung perfusion (EVLP) model and compare the effect of preservation between EVLP group and cold
storage group. Methods · Eight SD rats were reconditioned with EVLP for 4 h and 8 SD rats were under 3-h cold storage and 1-h EVLP. The biological
index, wet-to-dry weight ratio and concentration of Evans blue were analyzed between two groups. Results · Wet-to-dry weight ratio of lung tissue in
EVLP group was significantly lower (5.08±0.88 vs 6.09±0.48, P=0.012); Oxygenation index in EVLP group was significantly higher [(337.9±35.5) mmHg
vs (300.5±21.6) mmHg, P=0.023]; Concentration of Evans blue in EVLP group was significantly lower [(36.5±20.3) μg/mL vs (65.0±29.9) μg/mL,
P=0.043]. Conclusion · EVLP as an alternative to traditional cold storage technique can effectively alleviate the lung damage.
