Objective To compare the protecting effect of hypoxia preconditioning(HP) and deferoxam-ine preconditioning (DP)on transplanted livers and to search a protecting method which is suitable for clini-cal practice.Methods SD rats are randomly divided into four groups:sham operation group (S),analogic transplantation group (AT),deferoxamine preconditioning group (DP) and hypoxia preconditioning group (HP).Twenty-four hours after operation,several factors of each group were measured respectively,inclu-ding deterioration of histomorphology,hepatic zymogram in the serum,hypoxia inducing factor-1 (HIF-1α)and malonaldehyde (MDA) in hepatic tissue.Results The levels of alanine aminotransferase (ALT),glu-tamic oxalacetic transaminase (AST) and alkaline phosphatase (ALP) in AT group,DP group and HP group were higher than S group's.Levels of ALT,AST,ALP in AT group were dramatically high,hepatic tissue suffers from edema,degeneration even necrosis.By contrast,the pathological change is milder in DP group and HP group.HIF-1α in hepatic tissue of AT group was lower than that in DP group and HP group,MDA was higher than two latters (P < 0.05).Conclusion DP can protect transplanted liver as same as HP,however,DP is more suitable for clinical practice. 相似文献

直视微创手术技术在复杂肝外胆道手术中的应用 总被引:2,自引:0,他引:2
目的将直视微创手术技术应用于复杂肝外胆道手术,降低生理干扰、减少并发症。方法采用直视微创胆道外科手术器械,相对固定的手术步骤、技巧,施行胆囊三角区和胆囊床微创分离,胆囊管、胆囊动脉和胆总管的微创操作技术。结果本组137例复杂肝外胆道手术均在直视微创下完成。胆囊切除手术切口2.5~4.0 cm(平均3.8 cm),胆囊切除+胆总管切开取石、"T"型管引流手术切口4.0~5.0 cm(平均4.5 cm);除1例因胆道损伤于术后第11天行剖腹探查,胆总管空肠Roux-en-Y吻合术以外,其余无胆道损伤、术后出血及死亡病例;术后无痛或微痛。结论直视微创肝外胆道手术技术创伤小、适应证广。 相似文献

视疲宁片治疗视疲劳的临床观察 总被引:1,自引:0,他引:1
目的:观察中成药视疲宁片治疗视疲劳的临床疗效。方法:将80例视疲劳患者分为两组,每组40例。以服用视疲宁片者为治疗组,以服用补中益气丸及杞菊地黄丸者为对照组,进行临床观察。结果:治疗组总有效率为87.5%。用药后集合近点距离、调节近点距离明显变小,融合辐辏范围显著变大,且明显优于对照组(P<0.05)。结论:视疲宁片对改善患者视疲劳症状具有良好的作用。 相似文献
