二次自体骨髓干细胞移植治疗失代偿期肝硬化与首次移植对比研究

目的 比较失代偿期肝硬化患者行自体骨髓干细胞二次移植与首次移植对肝功能的影响。方法2007年5月至2009年12月在沈阳军区总医院住院治疗的45例失代偿期肝硬化患者，分为首次移植组和二次移植组。首次移植组23例患者均经内科治疗，症状平稳后行经股动脉自体骨髓干细胞移植术。二次移植组的22例患者则在首次移植后4～12个月行第二次干细胞移植。所有患者均于每次自体干细胞移植后第4、8周复查血常规、凝血指标及肝功能生物化学指标。结果 二次自体骨髓干细胞移植8周后，肝功能多项指标明显改善，血浆白蛋白(Alb)由移植前的(37.26±5.90) g/L升至(42.49±4.80) g/L(P＜0.01)，丙氨酸转氨酶(ALT)由（57.05±45.51）U/L降至（44.86±29.19）U/L(P＜0.05)，天冬氨酸转氨酶(AST)由（53.73±24.98）U/L降至(39.14±15.07) U/L(P＞0.05)；凝血功能各项指标明显好转，凝血酶原时间由（16.15±3.01）s降至(14.63±2.32) s(P＜0.01)，纤维蛋白原(Fib)由(2.44±0.61) g/L升至（3.00±0.81）g/L(P＜0.01)。与首次移植组患者同期相比，二次移植组移植8周后血浆Alb水平进一步升高，由（38.00±6.33）g/L升至(42.49±4.80) g/L(P＜0.05)，AST、ALT也明显改善，两组间差异有统计学意义，同时Child-Pugh B级患者的评分由(7.22±0.67)分降至（6.67±0.71）分(P＜0.05)。二次干细胞移植后，部分凝血指标及胆红素与首次移植组相比差异无统计学意义，但与干细胞移植前相比仍有改善。结论失代偿期肝硬化患者行二次自体骨髓干细胞移植可进一步改善肝功能，维持肝硬化症状的缓解期。

Comparation between first and second autologons bone marrow stem cells transplantation treatment in decompensated liver cirrhosis patients

Objective To compare the effect of autologous bone marrow stem cells transplantation on liver function between first and second transplantation in decompensated liver cirrhosis patients.Methods A total of 45 decompensated liver cirrhosis patients were enrolled, and 23patients in first transplantation group were transplanted with autologous bone marrow stem cells through femoral artery when condition was stable after medical treatment.In second transplantation group, 22 patients were accepted second transplantation in 4-12 month after the first transplantation.All the patients undergone routine blood test, congulation test and liver function examination at the fourth week and eighth week after transplantation.Results Eight weeks after transplantation, the liver function was improved obviously in both first and second autologous bone marrow stem cells transplantation.The level of albumin in patients of second transplantation group increased from (37.26± 5.90) g/L before transplantation to (42.49 ± 4.80) g/L (P＜0.01), alanine aminotransferase (ALT) decreased from (57.05±45.51) U/L to (44.86±29.19) U/L (P＜0.05),aspartate aminotransferase (AST) decreased from (39.14-±-15.07) U/L to (53.73 ± 24.98) U/L(P＞0.05).Congulation parameters were also improved, prothrombin time (PT) decreased from (16.15±3.01) s to (14.63±2.32) s (P＜0.01), fibrinofen (Fib) increased from (2.44±0.61) g/L to (3.00±0.81) g/L (P＜0.01).Compared with first transplantation group, the albumin level was higher in second autologous bone marrow stem cells transplantation group, which increased from (38.00±6.33) g/L to (42.49±4.80) g/L (P＜0.05), AST and ALT also improved obviously, and there was significant difference between two groups.Meanwhile, Child-Pugh scores decreased from (7.22±0.67) to (6.67±0.71) (P＜0.05).But there was no significant difference in bilirubin, FIB and PT.Conclusion The second transplantation of autologous bone marrow stem cells could further improve liver function and maintain symptoms remission of liver cirrhosis.
