文题释义:
干细胞移植治疗肝硬化的途径:
主要有肝动脉、门静脉、脾动脉、外周静脉、脾脏注射、腹腔内注射等途径。理论上经肝动脉或门静脉途径移植治疗肝硬化的效果最理想,因为肝脏本身才是干细胞定植、分化、增殖的最佳场所。肝硬化常常合并门静脉高压,经门静脉途径移植干细胞,可能经过广泛的门-体静脉循环或动脉-静脉-门静脉之间的分流引起门静脉的栓塞,从而导致肝功能的衰竭和严重的门静脉高压,消化道出血;同时移植的干细胞还有可能经过门-体静脉循环迁移到肺组织并引起肺栓塞,因此,临床上经门静脉途径移植干细胞受到一定限制。肝动脉血流速度快,移植的干细胞的“着床”时间过短,干细胞在肝脏内分化、增殖的数量较少。因此如何使移植的干细胞更多的在肝内停留、分化是一个重要问题,也是经肝动脉途径骨髓干细胞移植治疗肝硬化的关键。
谷丙转氨酶:存在于肝脏、心脏和骨骼肌中,主要存在于肝细胞浆内,其细胞内浓度高于血清中      1 000-3 000倍。肝细胞或某些组织损伤或坏死,都会使血液中的谷丙转氨酶升高。1%的肝细胞损伤可以使血液中的丙氨酸转氨酶浓度升高1倍。因此,谷丙转氨酶是反映肝细胞受损程度最灵敏的指标,在肝功能检查中最为常用。

 

摘要
背景:
如何使移植的骨髓干细胞更多的在肝内停留、分化是一个重要问题,也是经肝动脉途径移植骨髓干细胞治疗肝硬化的关键。
目的:探讨经肝动脉途径移植自体骨髓干细胞对肝硬化的治疗效果。
方法:将30只新西兰大白兔随机分为3组:正常对照组,干细胞移植组,模型对照组,每组10只。正常对照组不做任何处理,其余2组均建立肝硬化模型,干细胞移植组经肝动脉途径给予自体骨髓干细胞。在骨髓干细胞移植后的第1,2,4,8,10周分别检测肝功能指标,在第10周进行肝脏病理学检查。
结果与结论:①骨髓干细胞移植第10周,干细胞移植组血清谷丙转氨酶、总胆红素、谷草转氨酶水平有所降低,活化部分凝血激酶时间明显减短,白蛋白水平升高,与模型对照组比较,差异有显著性意义(P < 0.05);②干细胞移植组肝细胞形态完整,没有明显的水肿,假小叶结构仍然存在,与模型对照组比较,肝组织的纤维化程度明显减轻;③结果表明,经肝动脉途径移植自体骨髓干细胞可在短时间内提高体内白蛋白含量,改善机体肝功能,对肝硬化具有一定的治疗作用。

Abstract:

BACKGROUND: How to make more transplanted bone marrow stem cells stay and differentiate in the liver is an important issue, which is also crucial for treatment of liver cirrhosis via the hepatic artery.
OBJECTIVE: To investigate the therapeutic effect of autologous bone marrow stem cell transplantation via the hepatic artery on liver cirrhosis.
METHODS: Thirty New Zealand white rabbits were equivalently randomized into normal control, stem cell transplantation and model groups. Animal models of liver cirrhosis were made in the latter two groups. Then, model rabbits in the stem cell transplantation group were subjected to autologous bone marrow stem cell transplantation via the hepatic artery. Liver function of rabbits was detected in 1, 2, 4, 8, 10 weeks after cell transplantation, and pathological detection of the liver was performed in the 10th week.
RESULTS AND CONCLUSION: At 10 weeks after cell transplantation, the liver function of the rabbits was improved significantly compared with the model group, including reduced activities of serum alanine aminotransferase, total bilirubin and aspartate aminotransferase, shortened activated partial thromboplastin time, and increased albumin level (P < 0.05). Pathological examination of the liver showed that the liver cells in the stem cell transplantation group were intact with no obvious edema and still had the structure of the pseudolobule, and compared with the model group, the degree of liver fibrosis was significantly reduced in the stem cell transplantation group. Our experimental results show that the transplantation of autologous bone marrow stem cells via the hepatic artery has a certain therapeutic effect on liver cirrhosis by increasing the body albumin content in a short time and improving the liver function.
