Objective To study the role of NF-?B pathway in HGF (hepatocyte growth factor)-mediated proliferation of WB F-344 cell. Methods WB F-344 cells were treated with HGF in different concentrations i.e. 0, 20, 40, 80 and 100ng/ml. After incubation for 24 hours, proliferation effect was analyzed with [3H] Thymidine. WB F-344 cells transfected with I?B? plasmid mutants by liposome transfection were used to block NF-?B activity, and then they were treated with 40ng/ml HGF for 0, 15, 30, 60 and 120min, respectively. The nucleoprotein was extracted to determine the NF-?B DNA-binding activity by EMSA. WB F-344 cells were also transiently transfected with BD Great EscA PeTM SEAP vector with liposome and then stimulated with HGF in different concentrations (0, 10, 20, 40ng/ml) for 8 hours to detect the NF-?B transcription activity. WB F-344 cells were pre-treated with NF-?B inhibitor BAY-11-7082 or ASA, and then with 40 ng/ml HGF for 24 hours to analyze the proliferation effect by [3H] Thymidine. Results HGF promoted the proliferation of WB F-344 cells and exhibited positive dose-effect tendency. HGF could enhance the NF-?B DNA-binding activity. NF-?B complexes appeared 15min after addition of HGF. The complexes reached the peak value 30-60min after addition of HGF and then decreased gradually. HGF could also enhance the NF-?B transcription activity, exhibiting positive dose-effect tendency. HGF-mediated proliferation was remarkably inhibited when NF-?B activity was blocked by BAY-11-7082 or ASA. In WB F-344 cells transfected with p-CMV-I?B?, the proliferative response to HGF was completely interrupted. Conclusions HGF may promote the proliferation of WB F-344 cells in a positive dose-effect tendency. The activation of NF-?B is necessary for HGF-mediated proliferation of WB F-344 cells.

Objective To assess the efficacy and safety of aspirin for type 2 diabetes mellitus(T2DM).(Methods)Electronic database searching was performed on Medline,Cochrane Library and CBM,and the data from the beginning of the database to October 2005 were included.Randomised and quasi-randomised trials concerning aspirin treatment for T2DM were selected and assessed for the methodological quality,and the extracted data were performed Meta-analysis by statistical software RevMan4.2.8. Results Fourteen randomised and quasi-randomised trials met the inclusion criteria,including 7 papers of aspirin treatment for T2DM,3 papers of aspirin treatment for cardiovascular complication of T2DM and 4 papers of aspirin treatment for type 2 diabetic retinopathy.Compared with placebo treatment,aspirin showed significant positive effects on lowering blood glucose(SMD,0.73;95%CI,(-1.11 ~-0.36;)P=0.0001).In diabetic patients,aspirin treatment was associated with a significant reduction in the total cardiovascular events(RR,0.78;95%CI,0.68 ~ 0.98;P=0.03).Aspirin treatment neither lowered(nor increased) the risk of the development of diabetic retinopathy(RR,1.02;95% CI,0.97 ~ 1.07;P=0.54).(Conclusion Aspirin treatment) can be a choice for T2DM,especially for the patients who have evidence of cardiovascular disease or have high risks for cardiovascular disease.
