【摘要】Objective To study the role of tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) in CTD-IDL. Methods mRNAs were extracted from lung tissues and perip-heral blood mononaclear cells (PBMCs) of CTD-ILD patients. RT-PCR was deployed to detect the percentages of TNF-α mRNA, TGF-β mRNAs; and the percentage of TNF-α, TGF-β and fibrosing parameters (hyaluronic acid, HA) was tested in serum by ELISA. The relationship between above laboratory data and image as well as pathological characteristics were analyzed. Results The percentage of TGF-β mRNA in lung tissue and PBMCs. As well as the serum TGF-β and HA increased significantly in those with interstitial lung diseases. On the other hand, the percentage of TNF-α mRNA of these patients did not increase in lung tissues and PBMCs. Conclusion TGF-β plays a role in lung interstitial fibrosis. It may be helpful to understand the degree of fibrosis in lung tissue by detecting lung tissue/PBMCs TGF-β mRNA, serum TGF-β and other fibrosis indicators.%目的 了解肿瘤坏死因子(TNF)-α及转化生长因子(TGF)-β在结缔组织病相关的肺间质病变(CTD-ILD)发病过程中的作用.方法 提取患者肺
