METHODS: We measured levels of blood hydroperoxides as an indexof oxidative injury of cellular components, as well as plasmaferric-reducing ability as an index of total antioxidant potential,during sigmoidectomy under four conditions: open sigmoidectomywith sevoflurane anesthesia, laparoscopic sigmoidectomy withsevoflurane anesthesia, open sigmoidectomy with propofol anesthesia,and laparoscopic sigmoidectomy with propofol anesthesia.

在四种不同麻醉方法下乙状结肠切除术中，测定血液中的过氧化氢水平作为细胞氧化损伤的指标，以及血浆铁还原能力作为总抗氧化潜力的指标：七氟醚麻醉开腹乙状结肠切除术，七氟醚麻醉腹腔镜下乙状结肠切除术，异丙酚麻醉开腹乙状结肠切除术，异丙酚麻醉腹腔镜下乙状结肠切除术。

The results showed that the hardness of CGHAZ is decreasing,bainite ferrite strip coarsens,the shape of M－A constituents transforms strip into block,its size becomes large,and its bulk extends, with increasing of t8/5.In addition austenitic,M－A constituents in γ grain boundary coarsens and manifolds with increasing of t8/5.They all deteriorate the toughness of pipeline.And the extended zone of impact fracture shows brittle.

结果表明，随着t8/5的增加，粗晶区硬度逐渐减小，贝氏体化铁素体粗化，且其间的M－A组元由条状转变为块状，平均弦长增加，体积分数增大，奥氏体晶界M－A组元增多变粗，管线钢的韧性恶化，抗裂性变差，冲击断口扩展区呈脆性断裂。
