Objective To investigate the expression of hepatocyte growth factor activator inhibitor- 1 (HAl-1) gene in the tissues of renal cell carcinoma (RCC) and the correlation with tumor angiogenesis.Methods The expression of HAI-1 gene was detected by semi-quantitative RT-PCR in the tissues of 56 cases of RCC,corresponding adjacent non-cancer tissues and 12 nomad renal tissues,the expression of CD34was detected by immunohistochemistry SP method in the above-mentioned organizations,and counted the microvessel density (MVD),analyzed the relationship between the expression of HAI-1 gene in RCC and clinicopathological parameters,MVD.Results The positive expression rate of HAI-1 gene in RCC tissues,the adjacent non-cancer tissues and normal renal tissues were 58.93％(33/56),76.79％(43/56) and 91.67％(11/12),respectively.The expression of HAI-1 gene was a negative correlation to the Fuhrman histological grade,Robson clinical stage (r ＝ -0.617,-0.432,P ＜ 0.01 or ＜ 0.05 ).The positive expression rate in lymph node metastasis was significantly lower than that in without lymph node metastasis [ 35.29％(6/17) vs.69.23％(27/39),P＜ 0.05 ].The MVD in RCC tissues was significantly higher than that in the adjacent noncancer tissues and normal renal tissues(P＜ 0.05).The expression of HAI-I gene in RCC tissues was negative correlated to the MVD (r ＝ -0.516,P ＜ 0.01 ).Conclusions There is a certain relationship between the missing expression of HAI-1 gene in RCC and the development,invasion and metastasis of RCC.The HAI-1 gene deletion can be used as an important molecular marker in the invasion and metastasis of RCC.

Objective To observe the effects of Triptolide on the expression of toll-like receptor 4 (TLR4) in renal ischemia/reperfusion (I/R) injury in rats. Methods A renal I/R model was established. Rats were randomly separated into the following experimental groups. Group 1, shamoperated control (n = 15) : rats were subjected to surgical manipulation, without the induction of renal ischemia. Group 2, I/R (n = 18): rats were subjected to left renal ischemia for 45 min followed by reperfusion. Group 3, TRI + I/R (n = 18): Before the I/R procedure (as in group 2), rats were intraperitoneally injected with TRI (0.4 mg/kg), once every day, three times. Rats were killed at the 1st, 3rd, and 5th day after I/R injury. The parameters of renal function were determined by autobiochemical analyzer. The expression of TLR4 was detected by RT-PCR and Western blotting. Results As comparedwith the sham-operated control group, serum BUN and Cr levels were significantly increased in the rats undergoing I/R procedure at the 1st, 3rd, and 5th day (P＜0. 01). After the treatment with TRI, the levels of BUN and Cr and the expression of TLR4 in the renal tissues were significantly decreased (P＜0. 05). Conclusion TRI could relieve renal I/R injury in rats by inhibiting the TLR4 expression.

ObjectiveTo investigate the protective effect of ozone oxidative preconditioning (OzoneOP) on apoptosis induced by acute renal ischemia/reperfusion (I/R) injury in rats.Methods The right kidneys of rats in control group were excised.A rat I/R model was established in I/R group.In OzoneOP group,the renal OzoneOP was induced by rectal insufflation of 5.0～5.5 ml oxygen plus ozone (ozone 50 mg/L,1 mg· kg- 1 · d- 1,once every day).The parameters (blood urea nitrogen and creatine )of renal function were determined by auto-biochemical analyzer. The concentrations of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured by using chromometry.Cytochrome c (CytC) was examined by using immunohistochemistry and Western blotting.The mRNA expression levels of TNF-α,IL-1β and IL-6 in the renal tissue were detected by using RT-PCR.ResultsCompared with the control group,the blood urea nitrogen,creatine,MDA and the release of CytC were increased significantly in I/R group.After OzoneOP,the levels of blood urea nitrogen,creatine,MDA,CytC and the mRNA expression levels of TNF-α,IL-1-β and IL-6were significantly decreased and SOD levels were significantly increased.ConclusionOzoneOP could relieve renal I/R injury of rats by improving antioxidation capability,cutting down cytokines contents and inhibiting the release of CytC from mitochondria.

Objective To evaluate the predictive value of urinary neutrophil gelatinase-associat-ed lipocalin (NGAL) and interleukin-18 (IL-18) for delayed graft function (DGF) in kidney transplan-tation. Methods Serial urine samples collected at 0, 12 and 24 h after operation from 86 kidney transplantation patients were analyzed by enzyme-linked immunosorbent assay for NGAL, IL-18 and RBP. Results Fifteen patients developed DGF. At 12 h after transplantation, the level of urine NGAL elevated significantly (1712.75±474.6 vs. 863.1±199.8 without DGF, P<0. 001). The in-creases of urine IL-18 (29. 2±4.1 vs. 28.7±4.2 without DGF, P>0. 05) was not significant. At 24 h, both urine NGAL(2905.0±1108.1 vs. 911.8±221.0 without DGF,P<0. 001) and IL-18(211.3± 34.0 vs. 86.9±22.8 without DGF, P<0. 001) increased significantly, whereas the changes of urine RBP and serum creatinine (SCr) were not significant. ROC analysis showed that the area under the curve of NGAL and IL-18 were 0. 90 and 0.76 respectively, the cut-off values were 996.5 ng/mg and 148.5 ng/mg, the diagnostic sensitivities in DGF were 90.2% and 76.3%, specificities were 82.6% and 66.4% respectively. Conclusions Both urine NGAL and IL-18 could potentially be early predic-tive marker of DGF. The level of NGAL elevated earlier than IL-18, which may be more effective in predicting DGF.

OBJECTIVETo evaluate the basic principles of surgical correction of concealed penis.

METHODSFrom Jan. 1999 to Dec. 2002, 63 cases of concealed penis, aged from 1 year and 6 months to 19 years with a mean age of 7 years and 2 months, were corrected with two different approaches: 37 cases of group A with obesity were corrected by anchoring micrus tissue onto the pubis at the base of the penis, and 26 cases of group B by fixing the subcutateous tissues at both sides of the penile shaft to the deep tunica albuginea at the penile root. Then prepuce plasty was carried out.

RESULTSSix-month postoperative follow-up found adequate exposure of the penis in all of group A, prepuce oedema in 7 cases, abdomen fat liquidization in 3 cases, unsatisfactory recovery of incision hollow in 3 cases and patchy numbness of the glans in 1 case. The 25 cases of group B had satisfactory exposure of the penis, with no obvious prepuce oedema, 1 case with retraction of the penis 7 days after operation.

CONCLUSIONSVarious surgical procedures could be adopted for concealed penis, and the key to the satisfactory appearance is the restoration of penile tunicae and the fixation at the base of the penis. Further study is needed to determine the natural history of these disorders as well as which conditions and what age will benefit most from surgical intervention.

Objective To compare clinical efficacy and safety between standard double-and single-dose of basiliximab in renal transplantation.Methods A total of 121 patients undergoing allogeneic cadaveric renal transplantation in Department of Urology of Renmin Hopsital of Wuhan University from January 2008 to May 2011 were recruited as study subjects.Among them,53 patients were assigned into the double-dose of basiliximab group and they were intravenously administered with 20 mg of basiliximab before and 4 d after surgery according to product description.Sixty-eight cases were allocated in the single-dose of basiliximab group and they were given with 20 mg of basiliximab before renal transplantation.The changes of immune function in two groups during perioperative period were monitored.The incidence of adverse reactions including delayed graft function (DGF),acute rejection,pulmonary infection and the survival of patients and renal grafts were statistically compared between two groups.Results There was no significant difference in preoperative humoral immune and cellular immune function between two groups.Compared with preoperative period,cellular and humoral immune function in both groups were inhibited by varying degree at 5 d after surgery (both in P <0.05).Compared with patients in the single-dose group,cellular and humoral immune functions were evidently suppressed in the double-dose group (both in P <0.05).Compared with the parameters assessed at 5 d after surgery,cellular and humoral immune functions were restored to varying degree at 15 d after surgery,whereas still significantly lower than preoperative levels (CD3,CD4,IgM and IgA).Partial parameters (CD8 and IgG)were persistently inhibited and continued to decline compared with the levels at 5 d after surgery.The incidence of DGF was 8% in the double-dose group,and 7% in the single-dose group.During 1-year follow-up,the rejection rates in the double-and single-dose groups were 13% and 12%,and the incidence of pulmonary infection was 9% and 10%.No statistical significance was noted between two groups in terms of these parameters (all in P >0.05).The 1-year survival of patients in the double-and single-dose groups was 94% and 98%,93% and 96% for the survival of renal grafts.No statistical significance was found between two groups (both in P >0.05).Conclusions Both double-and single-dose of basiliximab are efficacious in renal transplantation and do not increase the incidence of adverse reaction.The 1-year survival rates of patients and renal grafts between two groups are almost equivalent.Detection of immune function during perioperative period effectively guides individualized immune induction therapy.
