摘　　要：目的了解联合肝脏分隔和门静脉结扎的二步肝切除术(ALPPS)动物模型及其基础研究的最新进展,为ALPPS的基础研究和临床应用提供新的思路。方法收集有关ALPPS的基础研究和动物模型的相关文献进行分析并作综述。结果至2018年3月,国内外公开报道的ALPPS动物模型相关文献共计19篇,其中大鼠模型11篇,小鼠模型4篇,猪模型2篇,兔模型1篇,羊模型1篇。文献以正常肝背景下模拟的ALPPS手术为主(16篇),其他包括结直肠肝转移小鼠ALPPS模型2篇,肝硬变背景下的ALPPS动物模型仅有1篇中文文献报道。ALPPS建模时,门静脉分支的结扎比例为20%～90%,根据缺血线及肝脏韧带来定位和分割肝脏,断面多以缝扎、电凝等方式止血。以上动物模型在术后均能观察到剩余肝组织增生。增生的主要原因:一是来于细胞因子,如肝细胞生长因子(HGF)、肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)等参与诱导肝细胞增殖相关基因表达的上调,二是剩余肝的门静脉及肝动脉血流增加,加速了肝脏细胞增殖。结论动物模型是研究ALPPS手术安全性及术后肝脏增生机制的主要工具,但涉及伴有肝硬变背景的肝脏肿瘤模型的研究仍较少。ALPPS术后肝脏再生的机制仍处于探索中,还需要更多的基础实验和临床病例来进一步研究。Objective To understand the advances in animal model and basic research of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),and to provide new ideas for basic research and clinical application of ALPPS.Methods The literatures on the basic research and animal models of ALPPS were analyzed and reviewed.Results By March 2018,there were 19articles related to ALPPS animal models published,including 11 rat model articles,4 mouse model articles,2 pig model articles,1 rabbit model article,and 1 sheep model article.These models of ALPPS were mainly simulated in normal liver background (16 articles),only 2 mouse model of colorectal liver metastasis and 1 rat model of ALPPS under the sclerotic liver background on Chinese article.In cases of rat's models,portal blood flow deprivation of 20%-90% was finished by portal vein ligation,and the liver was localized and segmented according to the ischemic line and the ligaments of the liver,and the liver partition was mostly sutured and electrocoagulated to stop bleeding.In the above models,remnant liver hyperplasia was observed after surgery.The main causes of hyperplasia were serum cytokines-mediated [hepatocyte growth factor (HGF),interleukin-6(IL-6), tumor necrosis factor-alpha (TNF-α),and so on]enhancement of proliferative gene,and secondly preservation of the portal vein lobes to increase blood volume and to accelerate liver proliferation.Conclusions The animal model is the main tool to study the safety of ALPPS and liver regeneration,but there are still few studies in the models with liver cirrhosis and liver tumors.The mechanism of liver regeneration after ALPPS is still unclear,and more basic experiments and clinical cases are needed for further study.
