神经生长因子、可溶性Fas在病毒性心肌炎中的表达意义

目的探讨神经生长因子(NGF)、可溶性Fas(sFas)在病毒性心肌炎(VM患儿)中表达,及NGFs、Fas与免疫反应的关系,旨在为VM的诊断和治疗提供新的依据。方法收集25例急性期和18例迁延及慢性VM患儿血清,其中急性期12例患儿为连续检测,即在病程1个月内、1~2个月、3~6个月各检测1次。采用双抗体夹心酶联免疫吸附试验(ELISA)测定NGF、SFas水平,测定病程不同时期VM患儿两个指标水平变化,并与20例健康患儿作对照。结果血清NGF、sFas在VM患儿病程在1个月内、1~2个月迁延期及慢性期表达水平增高,与对照组比较有明显差异(P均<0.01),而病程2~3个月急性期患儿血清NGF、sFas的表达水平渐下降,虽然仍高于对照组,但无统计学意义(P均>0.05)。结论NGF、sFas可能参与VM发病的病理生理过程,NGFs、Fas水平增高进一步证实VM的发病与免疫因素有关。

Significance of Expression of Nerve Growth Factor and Slouble Fas in Children with Viral Myocarditis

Objective To investigate the expression of nerve growth factor(NGF) and slouble Fas(sFas) in children with viral myocarditis(VM),and the relationship with immunity,with the aim to provide evidence and basis for the diagnosis and treatment of VM.Methods The serum levels of NGF and sFas were detected by two-site enzyme-linked immunosorbent assy(ELISA) in 43 children with VM,and 20 normal heathy children as controls.Results The serum levels of both NGF and sFas in children with the acute stage(course in less than month and 1-2 months)and the procrastinate and chronic stages of VM were significantly higher than those of healthy children(P<0.01).But there was no significant difference in the exepression levels of NGF and sFas between the course of disease in 2-3 months and the controls(P>0.05).Conclusion The increased serum expression levels of NGF and sFas are related to the process of viral myocarditis,which confirms the relationship between the onset of VM and immune factors.
