观察弹簧圈联合组织胶栓塞治疗急性非静脉曲张性上消化道出血的疗效。选取2016年6月—2022年3月收治的60例急性非静脉曲张性上消化道出血患者作为研究对象,采用简单随机法分为两组,对照组在确定出血动脉后给予组织胶栓塞治疗,观察组在确定出血动脉后给予组织胶栓塞至血流基本停滞,然后加用弹簧圈栓塞。比较两组输血量、止血成功率、住院时间及并发症,检测两组术前及术后3、12 h时应激相关因子的变化;随访3个月,记录两组复发情况。观察组输血量(567.45±102.41)m L少于对照组的(897.12±123.85)m L,住院时间(7.44±1.54)d短于对照组的(9.02±1.79)d,止血成功率(100.00%)与对照组(96.67%)比较,差异无统计学意义(P>0.05)。术后3、12 h时,两组Cor、NE、IL-1β、TNF-α、IL-6明显较术前下降,而IL-10明显较术前升高,且观察组术后3、12 h时除IL-10外的其他指标均低于对照组,而IL-10高于对照组(P<0.05)。观察组总有效率为96.67%(29/30),高于对照组的80.00%(24/30)(P<0.05)。弹簧圈联合组织胶栓塞治疗急性非静脉曲张性上消化道出血可减少输血量,改善机体应激状态,降低炎症水平,缩短病程。

BACKGROUND: liver transplantation is so far the most effective therapeutic modality for end-stage liver diseases, but ischemia/reperfusion (I/R) injury represents a critical barrier to liver transplantation. Primary graft dysfunction and small-for-size syndrome are closely associated with I/R injury. Ischemic preconditioning (IPC) is defined as a brief period of liver ischemia followed by reperfusion, and has demonstrated protections against a prolonged I/R injury and improved the capacity of regeneration. The article aimed to review IPC literatures for the understanding of the effects of IPC on I/R injury involving in the procurement of donor liver and protective mechanisms. DATA SOURCES: A literature search of MEDliNE and Web of Science databases using 'liver transplantation', 'liver regeneration', 'hepatectomy', 'ischemia/reperfusion' and 'ischemic preconditioning' was performed, and then a large amount of related data was collected. RESULTS: The literature search provided a huge amount of evidence for the protective effects of IPC on I/R injury in liver transplantation, including reduction of blood loss in hepatectomy, intraoperative hemodynamic stability and its significant role in liver regeneration. The mechanism involves in balancing inflammatory cytokines, enhancing energy status and mitigating microcirculatory disturbance. CONCLUSION: IPC plays an essential role in hepatectomy before and after harvest of living donor liver and implantation of liver graft.
