Objective To investigate the effects of platelet-derived growth factor(POGF),basic fibroblast growth factor(bFGF)and epidermal growth factor(EGF)on the proliferation,migration and phenotypie modulation of airway smooth muscle cells(ASMCs)in vitro.Methods Cultured human ASMCs were stimulated with PDGF.bFGF,EGF or DMEM(control).Cell pmliferation was detected by BrdU incorporation and cell count.Cell migration was measured using Boyden's chamber.Reverse transcription-poly-merase chain reaction(RT-PCR)and Western blot analysis were used for the detection of sm-α-actin and sm-MHC mRNA and protein expression in ASMCs.Resuits The mitotic index(%BrdU-positive per total number of cells)of ASMCs stimulated with PDGF.bFGF and EGF were significantly higher than those in control(P<0.001 or P<0.05).And the cell number of ASMCs stimulated with PDGF,bFGF and EGFwere also significantly higher than those in control(P<0.05).The number of migrating cells treated with PDGF,bFGF and EGF were higher than that in eontrol(P<0.05).The expressions of sm-α-actin mRNA treated with bFGF and EGF were significantly lower than those in control.but it was higher than control when treated with PDGF.The expressions of sm-MHC mRNA treated with bFGF and EGF were significantly lower than those in control,but it was higher than control when treated with PDGF(P<0.01 orP<0.05).Theexpressions of sm-α-actin protein treated with bFGF and EGF were significantly lower than those in control,but it was higher than control when treated with PDGF(P<0.05).The expressions of sm-MHC protein treated with bFGF and EGF were significantly lower than those in control.but it was higher than control when treated with PDGF(P<0.05).Conclusion PDGF,bFGF and EGF can directly induce ASMCs,proliferation and migration in vitro;and meanwhile,the expressions of cells,contractive phenotype increased treated with PDGF and decreased treated with bFGF and EGF.

Role of chronic inflammation in type 2 diabetes and obesity has been recognized in the past few years. Examples of potent inflammatory cytokines are C-reactive protein (CRP),tumor necrosis factor-?(TNF-?) ,plasminogen activator inhibitor-1 (PAI-1) and interleukin-6 (IL-6). Inflammatory processes may have important roles in the development of type 2 diabetes,obesity and insulin resistance. This article reviewed the relationship between some inflammatory cytokines and diabetes, providing references for clinical diagnosis and treatment.
