ABSTRACT

AIM To explore the effect of Heidihuang Pills on renal fibrosis in a rat model of chronic renal failure(CRF)and its mechanism.METHODS Wistar rats were randomly divided into the blank group for normal feeding and the model group for the establishment of CRF rat models by 5/6 nephrectomy.Subsequently,the successfully established rat models were randomly divided into the model group,the Heidihuang Pills group(10.43 g/kg),and the Heidihuang Pills+IGF-1R blocker(JB1)group for a regimen of 7-day subcutaneous injection of 18 μg/kg JB1 followed by gavage of 10.43 g/kg Heidihuang Pills.Eight weeks after the administration,the rats had their serum levels of Scr and BUN detected;their pathological changes of renal tissue observed by HE and Masson staining;their renal protein expressions of TGF-β,HIF-1α and α-SMA detected by immunohistochemistry;their renal protein expressions of IGF-1R and TGF-β detected by Western blot;and their renal mRNA expressions of IGF-1R and TGF-β detected by RT-qPCR.RESULTS Compared with the blank group,the model group displayed increased serum levels of Scr and BUN(P<0.05);increased,degree of renal fibrosis,and renal fibrosis area(P<0.05);increased renal expressions of TGF-β,HIF-1α,α-SMA proteins and TGF-β mRNA(P<0.05);and decreased expressions of IGF-1R mRNA and protein(P<0.05).Compared with the model group,the Heidihuang Pills group displayed decreased serum Scr and BUN levels(P<0.05);decreased inflammatory cells in renal interstitium and the fibrosis degree(P<0.05);decreased renal expressions of TGF-β,HIF-1α,α-SMA proteins and TGF-β mRNA(P<0.05);and increased expressions of IGF-1R mRNA and protein(P<0.05).However,the administration of JB1 could weaken the improvement effect of Heidihuang Pills on renal fibrosis in CRF rats(P<0.05).CONCLUSION Heidihuang Pills can inhibit the renal fibrosis in CRF rats,and the inhibition process is related to up-regulated IGF-1 expression and promoted combination of IGF-1 and IGF-1R.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the safety of living related donors in short term after transplantation.</p><p><b>METHODS</b>Two hundred and fifty-one cases of living related donor kidney transplantation from May 2000 to July 2007 were analysed retrospectively. There were 117 male and 134 female aged from 22 to 72 years old, with a mean of 46.6 years old. The indexes were compared including serum creatinine (SCr), creatinine clearance (CCr), glomerular filtration rate (GFR) and quality of life before and after donation. Surgical complications were followed-up.</p><p><b>RESULTS</b>Donors' SCr was (75.9 +/- 17.2) micromol/L before donation, (107.4 +/- 21.2) micromol/L on 7 d after donation, (130.4 +/- 58.2) micromol/L at the 1(st) month and (116.1 +/- 24.1) micromol/L at the 3(rd) month. There were significant difference between any 2 time points (P < 0.01). CCr was (94.4 +/- 17.5) ml/min before donation and (63.5 +/- 17.8) ml/min on 10 d after donation (P < 0.01). In 62 donors, total GFR was (82.4 +/- 21.8) ml/min before donation. On 10 d after donation, GFR of remaining kidney was (57.4 +/- 14.1) ml/min which was 34.7% higher than GFR of this kidney before donation (42.6 +/- 11.8) ml/min. There was no significant difference in quality of life before living related donors and non-donor populations (P = 0.116). Surgical complications included splenic rupture in 1 case, descending colon rupture in 1 case and wound infection in 5 cases.</p><p><b>CONCLUSION</b>Living donor kidney transplantation is safe for donors, although part of indexes would vary within normal range during the early time after donation.</p>
