【摘要】 目的:研究特发性肺纤维化(idiopathic pulmonary fibrosis,IPF)患者血清中转化生长因子-β(transforming growth factor-β,TGF-β)与干扰素-γ(interferon-γ,IFN-γ)水平的变化,探讨这两种细胞因子在IPF发病机制中的作用及临床意义。方法:选取2014年3月-2016年9月本院住院治疗的IPF患者28例为IPF组;另选取同期本院健康体检者30例为正常对照组。采用酶联免疫吸附法测定研究对象血清中TGF-β、IFN-γ水平,并进行分析。结果:IPF组患者血清中TGF-β水平为(716.94±96.67)pg/mL,高于正常对照组的(279.24±45.14)pg/mL,IPF组患者血清IFN-γ水平为(1 210.33±365.47)pg/mL,低于正常对照组的(1 573.00±196.87)pg/mL,比较差异均有统计学意义(P<0.01)。血清中TGF-β与IFN-γ水平呈显著负相关(r=-0.823,P=0.008)。结论:TGF-β、IFN-γ均参与了IPF的发病机制,两者水平的变化对IPF的病情发展有一定影响,其中TGF-β促进纤维化的形成,而IFN-γ为抑制纤维化的细胞因子。

Significance of Changes in Serum Levels of TGF-β and IFN-γ in Patients with Idiopathic Pulmonary Fibrosis/ZHANG Xiaoling.//Medical Innovation of China,2018,15(06):137-140

【Abstract】 Objective:To study the changes in serum levels of transforming growth factor-β(TGF-β) and interferon-γ(IFN-γ) in patients with idiopathic pulmonary fibrosis(IPF),and to explore the role and clinical significance of these two cytokines in the pathogenesis of IPF.Method:A total of 28 patients with IPF in our hospital from March 2014 to September 2016 were selected as the IPF group,in addition,30 healthy persons in the same period were selected as the normal control group.The serum levels of TGF-βand IFN-γ were measured by enzyme-linked immunosorbent assay and analyzed.Result:The serum level of TGF-βin IPF group was (716.94±96.67)pg/mL,which was higher than(279.24±45.14)pg/mL in normal control group,the serum level of IFN-γ in IPF group was(1 210.33±365.47)pg/mL,which was lower than(1 573.00±196.87)pg/mL

in normal control group,the differences were statistically significant(P<0.01).The TGF-β was negatively correlated to the IFN-γ(r=-0.823,P=0.008).Conclusion:TGF-β and IFN-γ are all involved in the pathogenesis of IPF,the levels change has a certain effect on the development of IPF,in which TGF-β promotes the formation of fibrosis,and IFN-γ is a cytokine that inhibits fibrosis.

特發性肺纤维化(idiopathic pulmonary fibrosis,IPF)是复杂的致病因素激发的多种细胞因子和炎症介质参与的慢性炎症性疾病。目前IFP发病率呈现逐年增高的趋势,但是由于该类疾病病因繁多,尽管存在急性期,但常常隐匿起病,慢性病程,早期不易被发现,绝大多数病例确诊已属于晚期纤维化形成,对肺功能的破坏已是不可逆,所以一直以来该类疾病是呼吸系统疾病的诊疗难点。由于目前肺间质纤维化的发病机制尚未明确,目前没有特异性的治疗药物及方法,所采用的均是非特异性的对症、“量体裁衣”式治疗。所以探索发病的分子机制及新的干预靶点,对于延缓或阻止肺纤维化的发生发展有重要意义。多种致炎性细胞因子及化学趋化因子在IPF发生发展中起重要作用。有研究认为血清转化生长因子-β(transforming growth factor-β,TGF-β)与干扰素-γ(interferon-γ,IFN-γ)在IPF的发病机制中有一定的联系。本研究通过观察IPF患者血清TGF-β、IFN-γ水平,探求两者在IPF疾病进展中的作用及意义,通过对其发病机制的研究,为治疗提供新的靶物,提高临床对IPF的诊治水平,力求缓解纤维化进展,以帮助提高患者生存质量和生存期。……
