Objective: To investigate the effect of Astragalus on peritoneal macrophages function in stable continuous ambulatory peritoneal dialysis(CAPD) patients. Methods: 28 stable CAPD patients were included in this study.All the patients were treated with peritoneal dialysis fluid containing Astragalus(20 ml/2 L) in vivo for one week.Peritoneal macrophages function such as phagocytosis ratio、bactericidal ratio、excretion of cytokines(TNF-? and NO) and mitochondrial dehydrogenases activity(MTT assay) were examined ex vivo just before and after the treatment. In vitro,peritoneal macrophages isolated from effluent were incubated with RPMI 1640、CDF or CDF containing various concentrations of Astragalus. Then peritoneal macrophages function mentioned above were examined again and compared. Results:No significant difference was found in TNF-? level in effluent between before and after the treatment (100?63)ng/L vs (116?60)ng/L, (P=0.192). While comparing with pre-treatment, peritoneal macrophages function was improved significantly after the addition of Astragalus into dialysate (phagocytosis ratio: (34.8?12.7)% vs (43.4?9.3)%,P0.05).The results in these two groups were significantly lower than those in Astragalus groups(P0.05). While significant decreasing in NO level and mitochondrial dehydrogenases activity were observed in 8% Astragalus groups as compared with those in 2% Astragalus group(P

ObjectiveToexploretheeffectof ceremideonprocess of peritoneal mesothelial cells(PMCs) apoptosis induced by peritoneal dialysis solution(PDS).Methods PMCs were cultured with normal DMEM,1.5% PDS and 4.25% PDS.4.25% mannitol was used as high osmotic pressure control.Ceremide were detected by LC-MS-MS.Flow cytometry was used in apoptosis analysis.Bax,p53 and bcl-2 protein expressions were detected by Western blotting.Results (1) PDS caused the increase of intracellular ceremide in PMCs,and normal and high osmotic pressure controls had no such effect.As the acidic sphigomyelinase inhibitor,desipramine significantly inhibited the production of ceramide induced by 4.25% PDS [(56.08±12.24) μg/L vs (91.25:t:15.89) μg/L,P<0.01]. (2) Compared with 1.5% PDS,4.25% PDS stimulated PMCs apoptosis (26.65%±6.21% vs 4.04%±1.86%,P<0.01),up-regulated bax and p53 proteins expression (P<0.01),and down-regulated bcl-2 protein exprssion(P<0.05).Desipramine obviously inhibited the apoptosis induced by 4.25% PDS,decreased bax and p53 proteins expression,increased bcl-2 protein expression(P<0.05).Exogenous C2-ceremide reversed the effect of desipramine(P<0.05).Conclusion The increase of intracellular ceremide may play an important role in the PMCs apoptosis induced by high glucose PDS.
