摘 要:目的观察防已黄芪汤对兔肺缺血再灌注损伤的保护作用。方法将36只日本大耳白兔随机分为3组,每组12只,A组为对照组,B组为黄芪汤组,C组为防已黄芪汤组。制备兔在体肺缺血再灌注损伤模型。恢复灌注后4h(W4)、6h(T6)检测各组血清c反应蛋白(CaP)、超氧化物歧化酶(SOD)、丙二醛(MDA)和白细胞介素-6(IL-6)水平。结果T4、T6时段,SOD(B组:119.52±11.23、123.40±12.15;C组:125.34±12.56、129.38±11.54)较A组增加;MDA(B组:2.91±0.46、2.53±0.35、C组:2.85±0.32、2.56±0.24)、CRP(B组:2.89±0.17、2.37±0.13;C组:2.57±0.12、2.10±0.11)、IL-6(B组:697.24±47.62、654.35±37.21;C组:662.63±45.67、612.54±39.72)较A组均下降,差异有统计学意义(P〈0.01);C组较B组MDA、SOD差异无统计学意义(P〉0.05),CRP、IL-6明显改善(P〈0.05)。结论防已黄芪汤能明显减轻兔肺缺血再灌注损伤,其作用机制可能与抗氧化、清除氧自由基及降低全身炎症反应有关。Objective To study the pretective effect of the Fangji-Huangqi decoction on lung ischemia-reperfusion injury (IRI). Methods Thirty-six Japanese rabbits were randomly divided into three groups: IRI group (group A), Huangqi decoction group (group B) and Fangji-Huangqi decoction group ( group C). Rabbit lung IRI model was established in vivo. The C-reactive protein ( CRP), superoxide dismutase ( SOD), malondialdehyde (MDA) and interleukin (IL) -6 of serum were determined at 4th ( T4 ) and 6th h (T6) after reperfusion. Results At T4 and T6, as compared with group A, SOD levels ( B : 119. 52 ± 11.23, 123.40± 12. 15 ; C : 125.34 ± 12. 56, 129. 38 ± 11.54) were higher, while MDA levels (B: 2.91 ±0.46, 2. 53 ±0. 35; C: 2. 85 ±0. 32, 2. 56 ±0. 24), CRP levels (B: 2. 89 ±0. 17, 2. 37 ± 0.13; C: 2.57 ±0.12, 2.10 ±0.11), and IL-6 levels (B: 697.24 ±47.62, 654.35 ±37.21; C: 662. 63 ±45.67,612. 54 ±39. 72) were lower (P〈0. 01 ) in groups B and C. There was no statistically significant difference in MDA and SOD levels between group B and group C ( P 〉 0.05 ). The CRP and IL-6 levels were significantly improved in group C as compared with group B ( P 〈 0. 05 ). Conclusion Fangji-Huangqi decoction can obviously alleviate lung IRI in rabbits probably by antioxidation, removal of oxygen radicals and reduction of systemic inflammatory response.
