摘要:

背景:目前肝脏移植是治疗终末期肝病的最佳方法,UW液是公认的肝脏保存液,但是其价格昂贵,并且细胞外液高K+状态,与人的生理不符,常会导致患者瞬时高钾血症,引起心跳停止,因此研发新的器官保存液已经刻不容缓。
目的:观察自制KYL液对恒河猴肝脏缺血再灌注后的保存效果。
方法:实验选受体猴和供体猴各8只,每组分别包括KYL液组和UW液组各4例供体肝脏灌注并冷保存4 h,行同种异体原位肝移植。分别于移植后30 min、6 h,记录胆汁分泌量,采血检测谷草转氨酶、谷丙转氨酶、一氧化氮、内皮素1、肿瘤坏死因子α浓度,切取肝组织行光学显微镜检测。
结果与结论:两组移植后均有胆汁分泌,随时间延长胆汁分泌量增加(P < 0.05)。移植后30 min、6 h,KYL液组血清谷草转氨酶和谷丙转氨酶浓度均低于UW液组(P < 0.05),两组血清一氧化氮、内皮素1、肿瘤坏死因子α浓度差异无显著性意义(P > 0.05)。光学显微镜下肝组织形态学观察显示,UW液组较KYL液组肝细胞水肿明显。结果证实,KYL液在预防缺血再灌注损伤效果与UW液总体相当,部分效果略优于UW液。

Abstract:

BACKGROUND: At present, liver transplantation is the best method to treat end-stage liver disease. UW solution is recognized as the best liver preservation solution, but it is expensive. Moreover, the extracellular fluid of high K+ condition is inconsistent with human physiology. Because transient hyperkalemia of UW solution often causes cardiac arrest, research and development of the new liver preservation solution already brook no delay.
OBJECTIVE: To study the protective effect of self-designed KYL solution on ischemia reperfusion injury in macaque donor liver.
METHODS: A total of eight recipient macaques and eight donor macaques were selected in this study. Each group contained KYL solution group (n=4) and UW solution group (n=4). Donor liver was perfused and cryopreserved for 4 hours and subjected to allogenic orthotopic liver transplantation. At 30 minutes and 6 hours after transplantation, bile production was recorded. Blood was obtained and used to detect concentrations of aspartate aminotransferase, alanine aminotransferase, nitric oxide, endothelin-1 and tumor necrosis factor-α. Liver tissue was collected and detected under the light microscope.
RESULTS AND CONCLUSION: Bile secretion was found in both groups. Bile secretion production increased as time went on (P < 0.05). At 30 minutes and 6 hours after donor liver reperfusion, serum aspartate aminotransferase and alanine aminotransferase concentrations were lower in the KYL solution group than in the UW solution group (P < 0.05). No significant difference was found in levels of serum nitric oxide, endothelin 1 and tumor necrosis factor alpha between the two groups (P > 0.05). Under light microscope, morphological observation of liver tissue revealed that cellular edema was evident in the UW solution group than in the KYL solution group. Results suggest that the effect of KYL solution on preventing ischemia/reperfusion injury was identical to the UW solution, and partial effect was better than UW solution.
