| 目的 探讨高压氧预处理对皮瓣移植术后大鼠缺血再灌注损伤炎症反应的影响。 方法将SD大鼠56只按随机数字表法分为假手术组（SH,n=8），缺血再灌注组(IR,n=24)和高压氧预处理后缺血再灌注组（HBO,n=24），IR组和HBO组再根据取血的时间各分3个亚组（IR 1d、3d、5d组和HBO 1d、3d、5d组），每个亚组8只大鼠。HBO 1d、3d、5d组于造模前3d进行高压氧预处理，每天2次（间隔12h），连续干预3d。7组均建立腹部带蒂移植皮瓣动物模型，SH组不夹闭或切断动静脉。造模成功后，SH组于术后第3天，其余6组则于对应的时间点应用酶联接免疫吸附剂测定(ELISA)法检测各组大鼠血清IL-23水平；同时采用组织损伤评分对SH组及IR 3d、5d组和HBO 3d、5d组的成活皮瓣进行组织学评分。 结果经高压氧预处理后，HBO 3d组IL-23水平为（17.80±14.78）ng/ml，显著低于IR 3d组的（38.91±12.26）ng/ml，差异有统计学意义（P<0.05）；组织学评分结果，IR 3d、5d组和HBO 3d、5d组的组织学评分分别为（2.66±0.44）分、（3.20±0.53）分、（1.85±0.31）分和（2.29±0.32）分，均显著高于SH组的（0.38±0.10）分，差异均有统计学意义（P<0.05），且HBO 3d、5d组组织学评分均显著低于同时间点的IR组，差异均有统计学意义（P<0.05）。 结论高压氧预处理可通过降低皮瓣移植术后大鼠IL-23水平来减轻皮瓣移植后缺血再灌注损伤的炎症反应。 |

| Objective To explore the effects of hyperbaric oxygen preconditioning on ischemia-reperfusion inflammatory reaction of rats after skin flap transplantation. MethodsFifty-six Sprague-Dawley rats were randomly divided into 3 groups: a sham ischemia-reperfusion (SH) group, an ischemia-reperfusion (IR) group and a hyperbaric oxygen reconditioning (HBO) group. Both IR group and HBO group were further divided into 3 subgroups, respectively, according to the time points of serum sampling for test post establishment of the IR model of the abdominal pedicle skin flap transplantation. The IR model of the abdominal pedicle skin flap transplantation was established in all the animals except those in the SH group, with those in the HBO group were preconditioned with HBO twice daily for 3 days before the operation. The blood was sampled at 1, 3 and 5 day post-operation to test the level of IL-23 using enzyme-linked immunosorbent assay (ELISA). The survival skin flaps were sampled from all the animals at 3 and 5 days after the operation for histological observation and evaluation. Results The average IL-23 level of HBO 3 d subgroup (17.80±14.78) was significantly lower than that of the IR 3 d subgroup (38.91±12.26). The average histological scores of the IR 3 d and 5 d subgroups, as well as HBO 3 d and 5 d subgroups were (2.66±0.44) and (3.2±0.53), (1.85±0.31) and (2.29±0.32), significantly higher than SH group (0.38±0.10). Moreover, the average histological score of the HBO 3 d and 5 d subgroups was significantly lower than IR 3 d and 5 d subgroups respectively. Conclusion Hyperbaric oxygen preconditioning can relieve the ischemia-reperfusion inflammatory reaction through reducing the serum level of IL-23 in rats after skin flap transplantation. |
