摘要:

背景:近年来研究发现,川芎嗪有清除氧自由基及保护血管内皮细胞的作用,大量的实验及临床研究涉及各种脏器,但对川芎嗪在皮瓣移植过程中缺血再灌注损伤的防治作用报道甚少。
目的:观察川芎嗪对大鼠腹部皮瓣组织缺血再灌注损伤的影响,并分析其作用途径。
方法:纳入24只健康SD大鼠,制备腹壁浅动脉为蒂的轴型缺血再灌注皮瓣。按随机数字表法分为假手术组、模型对照组和川芎嗪组,每组8只。假手术组皮瓣无缺血再灌注过程;模型对照组于造模前30 min给予生理盐水4 mL/kg;川芎嗪组造模后再灌注即刻给予川芎嗪4 mL/kg腹腔注射。模型对照组及川芎嗪组在皮瓣形成即刻、缺血8 h、再灌注1 h,假手术组在皮瓣形成即刻、术后8,9 h,取皮瓣中远处组织,测定组织匀浆内超氧化物歧化酶活性及丙二醛含量,光镜及电镜下观察组织形态学变化。
结果与结论:缺血8 h、再灌注1 h,模型对照组皮瓣组织中超氧化物歧化酶活性显著低于假手术组(P < 0.05~0.01),川芎嗪组皮瓣组织中超氧化物歧化酶活性显著高于模型对照组(P < 0.05~0.01)。再灌注1 h,模型对照组皮瓣组织中丙二醛含量显著高于假手术组(P < 0.01),川芎嗪组皮瓣组织中丙二醛含量显著低于模型对照组(P < 0.01)。与模型对照组比较,川芎嗪组皮瓣超微组织结构、血管内皮细胞损伤轻。提示川芎嗪可以抑制中性粒细胞活化、黏附,减轻组织炎症反应,保护内皮细胞,拮抗自由基的脂质过氧化,对皮瓣缺血再灌注损伤有一定的防治作用。

Abstract:

BACKGROUND: Recent studies have demonstrated that ligustrazine removed oxygen-derived free radicals and protected vascular endothelial cells. Howerver, the effect of ligustrazine on skin flap ischemia-reperfusion injury was less reported.
OBJECTIVE: To investigate the effect of ligustrazine on skin flap ischemia-reperfusion injury, and to analyze reaction pathway.
METHODS: A total of 24 healthy SD rats were used to establish ischemia-reperfusion injured skin flap along superficial epigastric artery. All rats were randomly divided into sham-surgery, model control, and ligustrazine groups, with 8 rats per group. Ischemia-reperfusion injury was not induced in the sham-surgery group; saline (4 mL/kg) was given in the model control gorup 30 minutes prior to operation; an intraperitoneal injection of ligustrazine (4 mL/kg) was given in the ligustrazine group immediately after ischemia-reperfusion injury. Distal tissue was selected from skin flap in the model control group immediate after formation of skin flap, 8 hours after ischemia, and 1 hour after reperfusion, as well as in the sham-surgery group immediate after formation of skin flap, 8 and 9 hours after operation to measure superoxide dismutase (SOD) and malonaldehyde (MDA) contents. Histological morphology was observed under optic and electron microscopes. 
RESULTS AND CONCLUSION: At 8 hours after ischemia and 1 hour after reperfusion, SOD activity in the model control group was significantly less than in the sham-surgery group (P < 0.05-0.01), but the SOD activity in the ligustrazine group was significantly greater than in the model control group (P < 0.05-0.01). At 1 hour after reperfusion, MDA content in the model control group was significantly greater than sham-surgery group (P < 0.01), but the MDA content in the ligustrazine group was significantly less than in the model control group (P < 0.01). As compared with model control group, ultramicrostructure and vascular endothelial cell were mildly damaged in the ligustrazine group, suggesting that ligustrazine inhibited activation and adhesion of neutrophilic granulocytes, relieved inflammatory reaction, protected endothelial cells, resisted lipid peroxidation of free radicals, and prevented skin flap ischemia-reperfusion injury.
