Objective:To explore the effects of myofibroblast in the pathogenesis of oral submucous fibrosis(OSF).Methods:The expressions of ?-SMA in the tissues of OSF and normal control were detected by immunohistochemistry. Fibroblasts were isolated from oral mucosa of OSF patients and healthy controls and were cultured under stimulation by arecoline.The expressions of ?-SMA in OSF fibroblasts and normal fibroblast were detected by immunocellchemistry and RT-PCR.Results:(1)No positive expression was found in normal tissues except in the blood vessel,but in OSF tissue,?-SMA positive expression was found in many spindle cells in the oral submucousal layer.(2)Few fibroblasts in vitro from normal controls were ?-SMA positive.(3)Most of the second passage of OSF fibroblasts were ?-SMA positive(85.80%?3.56%). (4)The expression of ?-SMA in fibroblasts could not be increased by the stimulation of arecoline.Conclusion:Myofibroblasts may play an important role in the pathogenesis of OSF,and the appearrence of myofibroblasts in OSF may not be directly induced by the stimulation of arecoline.

Objective To investigate the effect of pigment epithelium- derived factor (PEDF) on p38MAPK-CREB pathway and the expression of fibronectin (FN) in human mesangial cells (HMCs) cultured with high glucose. Methods HMCs were treated with different concentrations of glucose and the osmotic control respectively in the presence or absence of PEDF for 24 h:normal glucose (5.6 mmol/L),24.4 mmol/L mannitol,high glucose (30 mmol/L),high glucose+PEDF(30 mmol/L glucose with 10 nmol/L PEDF,40 nmol/L PEDF or 100 nmol/L PEDF).After samples were collected,the expression of phospho-p38MAPK (p-p38) and p-CREB was assessed by Western blotting,while FN mRNA and protein expression was assessed with RT-PCR and ELISA respectively. Results In contrast to normal glucose and mannitol treatments,the expression of p-p38MAPK,p-CREB and FN increased significantly in high glucose group (all P< 0.01).However,PEDF abolished the up-regulation of p-p38MAPK,p-CREB and FN induced by high glucose (all P<0.05). Conclusion PEDF may inhibit fibrosis through P38MAPK-CREB pathway in diabetic nephropathy.
