AIM: To investigate the influence of dialysate on the cell morphology and the peritoneal membrane function in chronic peritoneal dialysis rats. METHODS: 40 SD rats were divided randomly into 4 groups. Except control group, other groups daily received infusion of 20 mL dialysate (4.25% dialysate(HG), 1.50% dialysate(LG), Riger's solution(RG)) respectively for 8 weeks. The peritoneal membrane function was investigated by peritoneal transport test, and the rat peritoneal mesothelial cells(PMCs)morphology was analyzed by the cell imprints. RESULTS: The intraperitoneal volume and net ultrafiltration in HG and LG groups were significantly lower, with D/P_(urea) significantly higher, and C_(urea) after 4 h of dialysis significantly lower than that in RG and control groups. The density of cell population from analysis of cell imprints in HG and LG groups was significantly lower, but the mean surface area were significantly larger than that in RG and control groups. These change had no difference between HG and LG group. Using the high glucose dialysate for 8 weeks significantly decreased the ultrafiltration volume ,which was significantly relate to the increasing of cell surface area (r=-0.896,P

AIM: To investigate the role of reactive oxygen species (ROS) in transforming growth factor-?1 (TGF-?1)-induced regulation of plasminogen activator inhibitor-1 (PAI-1) expression and plasmin activity. METHODS: Growth arrested and synchronized rat mesangial cells were stimulated by TGF-?1. In some experiments,cells were pretreated with BSO or with antioxidant NAC. Intracellular ROS production was visualized using a fluorescent dye. PAI-1 protein secretion by mesangial cells was measured by Western blot and PAI-1 mRNA by both RT-PCR and Northern blot. Plasmin activity was determined using a synthetic fluorometric plasmin substrate. RESULTS: Exogenous TGF-?1 significantly increased intracellular ROS concentration and upregulated PAI-1 mRNA and protein expression in mesangial cells and reduced the plasmin activity. TGF-?1-induced upregulation of PAI-1 mRNA expression was exaggerated by BSO[DL-buthionine-(S,R)-sulfoximine]. NAC (N-acetylcysteine) effectively reversed TGF-?1-induced PAI-1 mRNA overexpression and plasmin activity decreasing. CONCLUSION: TGF-?1 increases intracellular ROS generation. ROS acts as a signaling molecular to mediate TGF-?1-induced PAI-1 overexpression and decrease in plasmin activity.

AIM: To investigate the expression of Smad2 signal protein in peritoneal mesothelial cells and how transforming growth factor ?1 (TGF-?1) affects its expression. METHODS: Rat peritoneal mesothelial cells were cultured in different levels of TGF-?1 (0,1.25,2.5,10 ?g/L) for different time (0,5,15,30,60,120 min). Endogenous Smad2 expression was evaluated by RT-PCR and immunohistochemical assay. The alteration of subcellular location of Smad2 was determined by immunohistochemical assay. RESULTS: TGF-?1 induced Smad2 mRNA expression, which increased at 5 min, peaked at 30 min, and declined to baseline levels by 120 min, in a time-dependent manner. Smad2 mRNA expression induced by TGF-?1 was also in a dose -dependent manner. TGF-?1 induced Smad2 phosphorlylation and nuclear localization in both time-dependent and dose-dependent manner, which was concordant with mRNA expression. Smad2 translocated from cytoplasm to nuclear accumulation in response to TGF-?1, and peaked at 30 min. CONCLUSIONS: Smad2 is present in peritoneal mesothelial cells. TGF-?1 may activate Smad2 expression and translocation to nuclear in a time-dependent and dose-dependent manner. [

Objective To investigate and analyze the experience of planting and maintaining implantable venous access ports(IVAP) in management of post-operative breast cancer patients. Methods Breast cancer pa-tients receiving IVAP after surgery from Mar. 2011 to Jun. 2014 were retrospectively analyzed. The relative com-plications were documented and summarized during implanting operation. Results 468 patients received IVAP, among whom 451 patients underwent piercing implantation via right internal jugular vein, 15 patients underwent piercing implantation via right subclavian vein, and 2 patients underwent piercing implantation via left internal jugular vein. The mean cathe tering leng th was 12.8 cm for patients receiving IVAP via right internal jugular vein, ranging from 12 to 15 cm. Thereinto, 30(6.4%) patients experienced shot-term complications including 16 cases of puncture difficulty, 5 cases of accidental arterial puncture, 2 cases of extravasation, 2 cases of blood aspiration dif-ficulty and 5 cases of arrhythmia. Three cases had long-term complications as the following:one case of catheter-re-lated infection, one case of catheter lost, and one case of incision rupture. Conclusions IVAP is a safe and effec-tive intravenous infusion device. It is crucial to choose individualized implanting access and length by professional surgical team.

AIM: To investigate the effect of antisense oligonucleotides on expression of macrophage migration inhibitory factor (MIF) in macrophages. METHODS: MIF phosphorothioate oligonucleotides was designed and synthesized. The phosphorothioate antisense, sense and missense oligonucleotides of mouse MIF was transfected into macrophages, separately. After that, macrophages were incubated with LPS. Cell culture medium was collected for MIF protein detection by EIA. Cellular RNA was extracted and the expression of MIF mRNA was examined by RT-PCR analysis. RESULTS: LPS stimulation resulted in a specific time-dependent expression of MIF derived from macrophages. MIF mRNA and MIF protein level increased at 6 h and reached a plateau at 9-12 h after LPS stimulation. The macrophages treated with antisense oligonucleotides showed a significant decrease in MIF mRNA and MIF protein after LPS stimulation than those with LPS stimulation only and LPS plus sense or missense oligonucleotides (P
