Objective To investigate the levels of transformation growth factor-β1 (TGF-β1),vascular endothelial growth factor (VEGF) and insulin growth factor-Ⅰ (IGF-Ⅰ) role in the pathogenesis of serum of patients with combined pulmonary fibrosis and emphysema (CPFE).Methods Recruited 20 patients with CPFE,40 cases with idiopathic pulmonary interstitial fibrosis (IPF) and 40 cases with emphysema who were admitted to our hospital during July 2011 to February 2012.Serum levels of TGF-β1,VEGF and IGF-Ⅰ were detected by ABC-ELISA.Results Serum levels of TGF-β1 and IGF-Ⅰ were significantly higher in patients with CPFE and IPF than these in patients with emphysema (TGF-β1:(160.73 ± 40.62) ng/L vs.(167.35 ± 42.82) ng/L vs.(128.75 ±35.77) ng/L; IGF-Ⅰ:(179.65 ±60.73) ng/L vs.(192.32 ±58.75) ng/L vs.(148.73 ±49.67) ng/L,P ＜ 0.05 or P ＜ 0.01).The IPF group had significantly higher serum level of VEGF than the emphysema group ((506.12 ±82.37) ng/L vs.(437.31 ±62.58) ng/L,P ＜0.01).Serum levels of TGF-β1 and IGF-Ⅰ in CPFE and emphysema groups were positively correlated (r =0.885,0.918 respectively,P ＜ 0.01).Smokers in the CPFE group had significandy lower level of serum VEGF than those who did no smoke ((406.19 ± 66.94) ng/L vs.(482.88 ± 79.91) ng/L,t =-2.287,P =0.035).Conclusion Serum level of VEGF increased significantly in the IPF group,suggesting the participation of VEGF in pulmonary interstitial fibrosis.IGF-Ⅰ involved in the pathogenesis of pulmonary interstitial fibrosis.TGF-β1 and IGF-Ⅰ have a positive linear regressive relationship,which indicates that they may work synergistically in the process of the fibrosis.

Objective To discuss the role of p38MAPK signal pathway in the process of TWEAK inducing rheumatoid arthritis(RA) fibroblast-like synoviocyte(FLS) to synthesize MMP-9 and look for a new target for RA treatment. Methods RA FLS were primarily cultured and stimulated with TWEAK. Western blot was used to detect the expression of p-p38MAPK and p65 in RA FLS. FLS were pretreated by SB203580 or not. ELISA was used to detect the concentration of MMP-9 in cell-cultured fluid. The mRNA expression of MMP-9 was measured by RT-PCR. Results TWEAK( 100 ng/ml) can make p38MAPK phosphorylated and increased the expression of p65 protein in the cell nucleus. SB203580 can partially inhibit the expression of MMP-9 and MMP-9 mRNA produced by RA FLS which is induced by TWEAK. Conclusion TWEAK induced RA FLS to synthesize MMP-9, in that process, the p38MAPK signal trausduction pathway was in active state, and induced the expression of NF-κB.
