摘要:

目的 观察急性心肌梗死(acute myocardial infarction,AMI)患者骨髓单核细胞移植手术前后血浆尾加压素Ⅱ(UⅡ)和内皮素-1(ET-1)水平的变化,探讨骨髓单核细胞移植对血管活性物质的影响。方法 采集23例AMI患者在骨髓单核细胞移植术前、术后1 d及术后7 d静脉血,应用酶联免疫法测定血浆UⅡ和ET-1水平。结果 正常对照组人群血浆UⅡ浓度为(0.462±0.115)mg/L,AMI患者血浆UⅡ浓度(0.223±0.043)mg/L较对照组明显低下(P<0.05)。骨髓单核细胞移植1 d后,血浆UⅡ浓度有所升高,为移植术前的129%(P<0.05)。移植7 d后,血浆UⅡ浓度回降到移植前的114%,但与移植后1 d比较差异无统计学意义。与骨髓单核细胞移植术前比较,血浆ET-1水平在移植后1 d 明显降低,为移植前的61%(P<0.01),移植7 d后,ET-1水平较移植后1 d 略有回升,为移植前的71%(P<0.01)。 结论血浆UⅡ和ET1的水平在骨髓单核细胞选择性移植术前后发生明显改变,为探讨骨髓单核细胞移植改善心脏功能的机制提供了理论依据。

Abstract:

Objective To study the effect of intracoronary implantation of autologous mononuclear bone marrow cell(MBMC) on the plasma level of urotensin-Ⅱ(U-Ⅱ) and endothelin-1(ET-1) in patient with acute myocardial infarction(AMI). Methods Twenty-three patients with AMI who underwent intracoronary implantation of autologous MBMC were enrolled in this study. UⅡ and ET-1 levels were measured by radioimmunoassay. Results The U-Ⅱ level in AMI patients was lower than that of control group〔(0.223±0.043)mg/L, vs (0.462±0.115)mg/L, P<0.05〕. After MBMC implantation, U-Ⅱ levels increased to 129% on day one compared to pre-transplantation. Whereas ET-1 levels decreased to 61%(compared with pre-transplantation) one day after cell infusion. And both U-Ⅱ and ET-1 slightly increased again 7 days after transplantation compared with 1 day after transplantation. Conclusion The therapeutic effect of MBMC transplantation may be related to the changes of ET-1 and UⅡ plasma level.
