摘要
目的 建立一种门体转流下大鼠冷缺血再灌注损伤模型并与肝移植模型进行对比.方法 Wistar大鼠随机分为3组:A组(10只):对照组,B组(140只):肝移植组,C组(94只):脾脏移位肝脏冷缺血再灌注组.并进行门静脉压、肝功能及肝脏病理学变化检测.结果 B组和C组术后1d和7d均表现出特征性的缺血再灌注损伤表现.B组门静脉阻断后1 min和10 min门静脉压明显高于C组[1 min:(29.93±2.42) mm Hg比(22.91 ±4.01) mmHg,P<0.01;10 min:(57.12±4.44) mm Hg比(18.32±4.42) mm Hg,P<0.01).与A组比较,B组和C组术后即刻即出现胆红素(TBIL)、γ-谷氨酰转肽酶(GGT)和碱性磷酸酶(ALP)水平的明显升高(P<0.05),B组和C组术后1d出现TBIL、GGT、谷丙转氨酶(ALT)和ALP水平的明显升高(P<0.05),且B组改变明显高于C组(P<0.05).术后7d,B组GGT仍明显高于A和C组[B组和A组:(2.16 ±0.34) IU/L比(1.39±0.36) IU/L,P<0.05;B组和C组:(2.16±0.34) IU/L比(1.75±0.32) IU/L,P<0.05].C组2周生存率高于B组(P>0.05).结论 门体转流原位冷缺血再灌注损伤模型是理想的肝脏冷缺血再灌注损伤模型.
Objective To establish a rat model of in situ cold ischemia/reperfusion (I/R) with portosystemin shunt and compare to liver transplantation model. Methods Wistar rats were divided into three groups: group A (n = 10), control group; group B (n = 140), orthotopic liver transplantation group; and group C (n = 94), liver cold ischemia group with splenic transposition (LCI). The parameters meas- ured included portal venous pressure (PVP) , liver enzymes [ (total bilirubin (TBIL) , alanine aminotrans- ferase (ALT) , alkaline phosphatase (ALP) and GGT) , and 14-day survival rate. Results Both groups showed characteristic I/R histologie changes at 24th h and 7th day. PVP at 1 min and 10 min after porta hepatis clamping in group B was significantly higher than that in group C [ 1 rain : (29. 93 ± 2. 42) mm Hg vs. (22.91±4.01) mmHg,P〈0. O1; 10 rain. (57. 12±4.44) mmHgvs. (18.32±4.42) mmHg, P 〈 0. 01 ]. TBIL, GGT and ALP were higher in groups B and C than in group A on the postoperative day (POD) 0 (P〈0. 05). TBIL, GGT, ALT and ALP were higher in groups B and C than in group A on POD 1 (P 〈 0.05 ), and the index was higer in Group B than group C on POD 1 (P 〈 0. 05 ). GGT was still higher in group B than in groups C and A on POD 7 [groups B and A: (2. 16 ±0. 34) IU/L vs. ( 1.39 ±0. 36) IU/L; groups B and C: (2. 16±0. 34) IU/L vs. ( 1.75 ±0. 32) IU/L; P 〈0.05 for both]. The 14-day survival rate in group C was higher than in group A ( P 〉 0. 05 ). Conclusion LCI model is ideal for the study on cold I/R iniurv.
