Objective To explore the effect of the liver acquired expression of apolipoprotein B editing catalytic polypeptide-1 (Apobec-1) on hyperlipidemia of renal disease. Methods Thirty healthy ordinary level male New Zealand rabbits were randomly divided into three groups: sham operation group, nephropathy group, and Apobec-1 treatment group (Each group has 10 rabbits). Adapt feeding for one week, nephropathy group and Apobec-1 treat-ment group underwent left nephrectomy, and one week later, adriamycin (4 mg / kg) was used to construct the ne-phropathy model by ear vein injection. The eleventh week after operation, apobec-1 recombinant adenovirus (1 × 1013 Virus/ kg) was injected by ear vein in apobec-1 treatment group. The twelfth week after operation, all rabbits were sacrificed. Right kidney, liver, blood and 24h urine were left. In three groups, 24 hour urinary protein (24UPr), albumin (Alb), blood urea nitrogen (BUN), creatinine (Cr), blood lipid were detected. Renal pa-thology was observed by HE staining. Expressions of liver apobec-1, apolipoprotein B48(ApoB48)were observed by Western blot. Results ① Compared with the sham operation group, nephropathy group showed that 24UPr, BUN, Cr, total cholesterol (TC), total triglyceride (TG), very low density lipoprotein (VLDL-C), low density lipoprotein (LDL-C), apolipoprotein B100 (ApoB100) were increased(P < 0. 05), but Alb was decreased(P <0. 05). ② Compared with the nephropathy group, Apobec-1 treatment group showed that TC, TG, VLDL-C, LDL-C, ApoB100, ApoB48 were decreased(P < 0. 05). ③ Compared with the sham operation group, Apobec-1 treat-ment group showed that 24UPr, BUN, Cr were increased( P < 0. 05), but Alb, ApoB48 were decreased( P <0. 05). ④ Compared with the sham operation group and nephropathy group, Apobec-1 treatment group showed that the expression of Apobec-1 and ApoB48 were up-regulated (P < 0. 01). Conclusion When liver aquires expres-sion of Apobec-1 in hyperlipidemia of renal disease, it can reconstruct ApoB mRNA, increase the synthesis of ApoB48-lipoprotein, and play a certain lipid-lowering effect.

Objective To determine the expression of peroxisome proliferators-activated receptors (PPARs), nuclear factor-κB (NF-κB) and activity of superoxide dismutase (SOD) in rats with obstructive jaundice induced by bile duct ligation (BDL) and elucidate the molecular regulation mechanisms of hepatic injury due to obstructive jaundi(c)e. Methods All rats were sacrificed on the 7th day and 19th day after BDL and blood and liver tissue samples were obtained. SOD enzyme activity was detected by SOD kit. RT-PCR was performed to determine the mRNA expression of PPARs in all groups. The detection of PPARs protein and activation of NF-κB were performed using an immunohistochemical method. Results The activities of normal SOD and CuZn-SOD were decreased compared to the sham group (P<0.01), and the decrease on 19th day after BDL were more significant. The level of PPARs expression in the BDL groups liver except the PPARβ in the BDL 7th group was reduced compared to the sham group (P<0.01), and the level on the 19th day after BDL were more significantly reduced. PPARs protein expression was significantly inhibited (P<0.01) in the sham group. SOD in BDL groups had significant positive correlation as compared with PPARs protein expression (P<0.01), but NF-κBp65 protein expression had significant negative correlation as compared with PPARs protein expression (P<0. 01). Conclusion PPARs are inhibited in expression level, and this inhibition becomes more significant as the pathological process progresses. PPARs might be key regulatory factors for SOD and NF-κB. The low expression of PPARs might be one of the important molecular mechanisms in liver injury due to obstructive jaundice.

Objectives To study the expression features of C-type natriuretic peptide (CNP)/natriuretic peptide receptor-B (NPR-B) axis and two parallel elimination pathways, natriuretic peptide receptor-C (NPR-C) and neutral endopeptidase (NEP) in unilateral ureteral obstruction (UUO) rats. Methods CNP, NPR-B, NPR-C, NEP, Col-IV and type IV collagen (Col-IV) mRNA and proteins were determined by in situ hybridization, real-time PCR, immunohistochemistry and western blot in UUO rats at 24h, 72h, 1w, 2w, 3w, 1m, 2m and 3m. Results CNP expression tended to be higher immediately after ligation and de-clined along with the progression of disease, occurring predominantly in tubular epithelial cells. A high-level CNP may attribute to the elevated expression of NPR-B in the early phase of UUO. Conclusions NEP and NPR participate in the regulation of CNP expression in tubulointerstitial fibrosis. The gradual increased expression of NPR-C and NEP may cause the subsequent de-cline of CNP.
