目的通过大鼠原位肺移植模型，研究长征１号多器官保存液（简称“ＣＺ１液”）保存肺的效果。方法将大鼠随机分为３组：对组照：以平衡液灌洗供肺，并立即移植；ＣＺ１液组：以ＣＺ１液灌洗供肺，保存８小时后移植；ＥｕｒｏＣｏｌｉｎｓ液组：以ＥｕｒｏＣｏｌｉｎｓ液灌洗供肺，保存８小时后移植。结果移植肺缺血时间，ＣＺ１液组与ＥｕｒｏＣｏｌｉｎｓ液组间的差异不显著（Ｐ＞０．０５）；动脉血氧分压，对照组与ＣＺ１液组比较，差异显著（Ｐ＜０．０１），ＣＺ１液组与ＥｕｒｏＣｏｌｉｎｓ液组比较，差异显著（Ｐ＜０．０１）；动脉血ＣＯ２分压，对照组与ＣＺ１液组比较，差异不显著（Ｐ＞０．０５），ＣＺ１液组与ＥｕｒｏＣｏｌｉｎｓ液组间的差异显著（Ｐ＜０．０１）；移植肺的湿重／干重比值（Ｗ／ｄ），单纯保存时对照组的Ｗ／ｄ明显高于ＣＺ１液组和ＥｕｒｏＣｏｌｉｎｓ液组，而ＣＺ１液组明显低于ＥｕｒｏＣｏｌｉｎｓ液组（Ｐ＜０．０５），而保存后移植，对照组的Ｗ／ｄ明显低于ＣＺ１液组和ＥｕｒｏＣｏｌｉｎｓ液组，ＣＺ１液组明显低于ＥｕｒｏＣｏｌｉｎｓ液组（Ｐ＜０．０５）；移植肺病理改变，ＣＺ１液组的损伤轻于Ｅｕｒｏ?
OBJECTIVE: To study the effect of preservation of lung in Long March 1 multiple organ preservation solution (CZ1 solution) by rat orthotopic lung transplantation model. Methods The rats were randomly divided into 3 groups: the group photos: BAL fluid lavage for the lung, and immediately transplanted; CZ 1 liquid group: CZ 1 fluid lavage for the lung, preserved 8 hours after transplantation; Euro Colins liquid group: Euro Colins fluid lavage for the lung, preserved for 8 hours after transplantation. Results During the transplantation of lung ischemia, the differences between CZ-1 and Euro-Colins groups were not significant (P> 0.05); arterial partial pressure of oxygen was significantly different between the control group and CZ-1 group P <0.01). There was significant difference (P <0.01) between CZ1 solution group and EuroColins solution group. There was no significant difference between the control group and CZ1 solution group P> 0.05). There was significant difference between CZ1 solution and EuroColins solution group (P <0.01). W / d (W / D) Of W / d was significantly higher than that of CZ1 and EuroColins groups, while CZ1 was significantly lower than that of EuroColins (P <0.05), while W / D was significantly lower than the CZ 1 liquid group and Euro Colins liquid group, CZ 1 liquid group was significantly lower than Euro Colins Group (P <0.05); Transplantation pulmonary pathology changes, light damage was CZ1 group in Euro?
