摘  要:目的探讨人肝源性干细胞腹腔移植不同时间在刀豆蛋白A(ConA)诱导小鼠急性肝损伤中的保护作用。方法将88只雄性C57BL/6小鼠随机分成3组,正常小鼠对照组(C组),ConA模型组(M组),人肝源性干细胞(HYX1)+ConA组(E组),M组和E组根据注射磷酸盐缓冲液或HYX1后再注射ConA间隔时间不同,又分为3h(M1、E1)、6h(M2、E2)、12h(M3、E3)、24h(M4、E4)、48h(M5、E5)组。检测外周血丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、总胆红素(TBil)水平;小鼠肝组织切片观察各组病理变化,并进行肝脏炎症活动度Ishak评分。采用独立样本t检验进行组间比较,P〈0.05为差异有统计学意义。结果C组的ALT、AST及TBil分别为(36.25±1.16)U/L、(120.20±5.77)U/L、(2.20±0.23)μmol/L;M1~M5组的ALT、AST、TBil及肝脏Ishak评分分别为(8721.23±837.39)U/L、(8110.31±290.10)U/L、(8.41±0.10)μmol/L、13.32±1.30,(8334.31±666.50)U/L、(7560.20士760.34)U/L、(10.40±0.80)μmol/L、12.67±0.81,(8960.75±551.93)U/L、(8535.62±675.14)U/L、(10.95±1.43)μmol/L、14.57±0.65,(8618.57±886.40)U/L、(11440.54±1327.86)U/L、(13.30±1.86)μmol/L、13.21±1.06,(10170.13±1112.37)U/L、(11470.56±1108.40)U/L、(12.75±1.55)μmol/L、15.07±1.58;E1~E5组的ALT、AST、TBil及肝脏Ishak评分分别为(1016.35±163.47)U/L、(952.30±103.91)U/L、(7.77±0.62)μmol/L,3.50±0.21,(42.10±6.20)U/L、(126.72±13.33)U/L、(3.41±0.53)μmol/L、2.01±0.40,(44.21±4.30)U/L、(216.71±35.88)U/L、(3.47±0.44)μmol/L、2.13±0.25,(2909.69±212.14)U/L、(2988.43士333.70)U/L、(7.03±0.93)μmolObjective To investigate the protective effect of intraperitoneal transplantation of human liver-derived stem cells at different times against concanavalin A (ConA)-induced acute liver injury in mice. Methods A total of 88 male C57BL/6 mice were randomly divided into normal control group (group C), ConA model group (group M), and human liver-derived stem cells (HYX1)+ConA group (group E); according to the interval between phosphate buffer/HYX1 injection and ConA injection, Groups M and E were further divided into 3-hour groups (M1 and E1 groups), 6-hour groups (M2 and E2 groups), 12-hour groups (M3 and E3 groups), 24-hour groups (M4 and E4 groups), and 48-hour groups (M5 and E5 groups). The levels of alanine aminotransferase (ALT), aspartate transaminase (AST), and total bilirubin (TBil) in peripheral blood were measured, liver tissue sections were used to observe pathological changes, and the Ishak score for liver inflammation was determined, The independent samples t-test was used for comparison between groups, and P 〈 0.05 was considered statistically significant. Results The levels ofALT, AST, and TBil in group C were (36.25±1.16) U/L, (120.20±5.77) U/L, and (2.20±0.23) μmol/L, respectively; the levels of ALT, AST, and TBil and Ishak score were (8 721.23±837.39) U/L, (8 110.31±290.10) U/L, (8.41±0.10) μmol/L, and (13.32±1.30), respectively, in group M1, (8 334.31±666.50) U/L, (7 560.20±760.34) U/L, (10.40±0.80) μmol/L, and (12.67±0.81), respectively, in group M2, (8 960.75±551.93) U/L, (8 535.62±675.14) U/L, (10.95±1.43) pmoFL, and (14.57±0.65), respectively, in group M3, (8 618.57±886.40) U/L, (11 440.54 ± 1 327.86) U/L, (13.30±1.86) μmol/L, and (13.21±1.06), respectively, in group M4, and (10 170.13±1 112.37) U/L, (11 470.56±1 108.40) U/L, (12.75±1.55) μmol/L, and (15.07±1.58), respectively, in group M5.
