文题释义:
肝衰竭:
是多种因素引起的严重肝脏损害,导致其合成、解毒、排泄和生物转化等功能发生严重障碍或失代偿,出现以凝血功能障碍、黄疸、肝性脑病、腹水等为主要表现的一组临床症候群。肝衰竭分为急性肝衰竭、亚急性肝衰竭、慢加急性(亚急性)肝衰竭和慢性肝衰竭。近年来,干细胞技术的不断发展,为急性肝衰竭的治疗拓宽了道路。
糖原合成酶激酶3β:是一种丝氨酸/苏氨酸蛋白激酶,在细胞周期调节、细胞凋亡以及炎症反应中发挥着关键性作用。近期研究发现糖原合成酶激酶3β能够在急性肝衰竭中发挥免疫学调控作用,且抑制糖原合成酶激酶3β能够有效缓解肝损伤,提示糖原合成酶激酶3β可能成为治疗急性肝衰竭的潜在靶点。

 

摘要
背景:
间充质干细胞对肝衰竭大鼠的肝脏具有保护及修复作用,但具体机制尚未完全明确。
目的:观察人脂肪间充质干细胞尾静脉注射对急性肝衰竭大鼠肝脏损伤的保护作用,并探讨其可能的机制。
方法:将36只SD大鼠(购自青岛市大任富成畜牧有限公司)随机等分为对照组、模型组和移植组。模型组和移植组大鼠通过腹腔注射D-氨基半乳糖建立急性肝衰竭模型。造模1 d后,移植组注射人脂肪间充质干细胞悬液,模型组注射等量生理盐水。细胞移植1 d和3 d,检测血清中丙氨酸氨基转移酶、天冬氨酸氨基转移酶、总胆红素水平。细胞移植3 d,检测血清中肿瘤坏死因子α、白细胞介素6、白细胞介素10水平;苏木精-伊红染色观察肝脏病理形态学变化;Western blot检测肝组织中糖原合成酶激酶3β蛋白的表达。
结果与结论:①与模型组相比,移植组血清中丙氨酸氨基转移酶、天冬氨酸氨基转移酶、总胆红素、肿瘤坏死因子α、白细胞介素6和白细胞介素10水平降低(P < 0.05);②移植组肝脏组织炎症反应和变性坏死程度较模型组减轻;③移植组肝组织中糖原合成酶激酶3β活性较模型组减弱(P < 0.05);④结果表明,人脂肪间充质干细胞可以减轻急性肝衰竭大鼠肝脏炎症反应和病理损伤,改善肝脏功能,其机制可能与抑制糖原合成酶激酶3β活性有关。

Abstract:

BACKGROUND: Mesenchymal stem cells can protect and repair the liver of rats with liver failure, but the mechanisms are not completely clear.
OBJECTIVE: To explore the protective effects and related mechanisms of intravenous injection of human adipose-derived mesenchymal stem cells on acute liver failure in rats.
METHODS: Thirty-six Sprague-Dawley rats (provided by Qingdao Daren Fucheng Animal Husbandry Co., Ltd. in China) were randomly divided into control group, model group and transplantation group. Animal models of acute liver failure were established by intraperitoneal injection of D-galactosamine in the model group and the transplantation group. One day after modeling, the rats in the transplantation group were injected with human adipose-derived mesenchymal stem cell suspension, and those in the model group were injected with the same amount of saline. After 1 and 3 days of cell transplantation, the serum levels of alanine aminotransferase, aspartate aminotransferase, and total bilirubin were measured. Three days after cell transplantation, the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-10 were detected, the pathological changes of the rat liver were observed by hematoxylin-eosin staining, and the activity of glycogen synthase kinase-3β protein in the liver tissue was detected by western blot.
RESULTS AND CONCLUSION: Compared with the model group, there was a significant reduction in the serum levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, tumor necrosis factor-α, interleukin-6 and interleukin-10 in the transplantation group (P < 0.05). Inflammation and necrosis of liver tissues in the transplant group were alleviated compared with the model group. The activity of glycogen synthase kinase 3β in the liver tissue of the transplanted group was lower than that of the model group (P < 0.05). Overall, these results indicate that human adipose-derived mesenchymal stem cells can alleviate hepatic inflammation and pathological injury, and improve the liver function in rats with acute hepatic failure. Moreover, the mechanism may be related to the inhibition of glycogen synthase kinase 3β activity.
