内皮抑素在大鼠腹膜的表达及其与腹膜血管新生的关系

Objective To investigate the expression of endostatin (ES) in rat peritoneum and its association with peritoneal neoangiogensis. Methods Thirty-two male SD rats were randomly divided into 4 groups: normal control rats (C group), renal failure without PD rats (non-PD group), rats dialyzed with 1.5% PD solution (1.5% PD group) and 4.25% PD solution (4.25% PD group). After regular PD for 28 days, mRNA and protein expression of ES in peritoneal tissues of each group were detected by RT-PCR and immunohistochemistry respectively. Microvessel density (MVD) of peritoneal tissue was assessed using immunohistochemistry with CD34 monoclonal antibody. Results ES mRNA was expressed in each group, 0.47±0.05 in C group, 0.45±0.04 in non-PD group, 0.46±0.04 in 1.5%PD group, 0.47±0.03 in 4.25%PD group, and no significant differences were found among groups. Score of ES protein expression was O in C group, 2 in non-PD group, 4 in 1.5%PD group, and 9 in 4.25%PD group. MVD was 3.13±1.13 in C group, 5.13±1.14 in non-PD group, 9.00±1.51 in 1.5%PD group, 10.75±1.83 in 4.25%PD group, and significant differences were found among groups. Conclusion Uremia circumstance and non-physiological compatibility peritoneal dialysate can increase ES protein expression and MVD, which may participate in and have effects on the course of peritoneal neoangiogensis.

Abstract：

Objective To explore the protection of valsartan combined with simvastatin on kidney in early diabetic nephropathy rats. Methods Diabetic nephropathy rats model were induced by streptozocin (STZ) ,the experimental rats were randomly divided into 5 groups: control (group C), diabetic nephropathy (group D) ,diabetes treated with valsartan (group X) ,diabetes treated with simvastatin (group Z) ,and diabetes treated with combined valsartan and simvastatin ( group L). Blood glucose (BG), HbA1c, blood cholesterol ( TC), trigalloylglycerol ( TG ), blood ureanitrogen ( BUN ), serum creatinine (SCr) , urinary albumin excretion rate (UAER) were measured, and the podocyte ultrastructure was observed by transmission electronic microscopy. Results The levels of BG, HbA1c,TC,TG and UAER in group D increased significantly compared togroup C(BG:[20.3 ±3.2]mmol/L vs [6.1 -±0. 4]mmol/L;HbA1c:[7.18 ±0.47]% vs [3.37 ±0. 15]% ;TC: [2. 69 ±0. 35] mmol/L vs [1.28 ±0. 24] mmol/L;TG: [3.09 ±0. 37] mmol/L vs [1.18 ±0. 25]mmol/L) (P ＜ 0. 05 ). Creatinine clearance rates (Ccr) in group D ( [0. 89 ± 0. 19] ml/min ) decreased significantly compared to group C( [1.27 ±0. 33] ml/min) ,as well as group X,Z and L( Ps ＜ 0. 05 ). UAER in group D was significantly higher than that in group C ( [19. 87 ±3. 85] μg/24 h vs [3. 67 ± 1.01] μg/24 h) (P ＜ 0. 05 ), as well as group X, Z and L ( P ＜ 0. 05 ), and the improvement in group L was particularly significant ( P ＜ 0. 05 ). The projections of podocyte in group D severely syncretized, there were slightly improvement in group X, Z and L compared to group D, and the improvement in group L was remarkable. Conclusion The treatment with valsartan, simvastatin and their combination will effectively protect the kidney in early diabetic nephropathy rats,and the effect of using the combination therapy is much better.
