Objective To present the experiences in using the tubularized incised plate urethroplasty (Sondgrass procedure) for hypospadias repair. Methods Tubularized incised plate urethroplasty was performed for 43 cases of hypospadias including 35 distal penile shaft and 8 penoscrotal hypospadias.9 children have had a history of failed urethroplasty.Dorsal plication was carried out for 10 chordees.Bladder drainage was maitained for 10 days.After withdrawing the drainage,regular urethral dilatation was conducted. Results The patients have been followed up for 4～11 months and a good functional neourethra with a vertical slit like meatus was observed.There has been no chordee or stricture.5 patients had urethro cutaneous fistula,4 have been corrected. Conclusions Tubularized incised plate urethroplasty can be used in distal and proximal hypospadias repair including those with chordee and is especially indicated for patients without enough penile skin after failed urethroplasty.

Objective To evaluate diuretic renogram (DR) in the assessment of therapeutic effect on dilated upper urinary tract in children. Methods A total of 54 children with 66 sides of dilated upper urinart tract undergone surgery had been followed up by DR examination. Results According to the renal blood perfusion rate (BPR),the dilated upper urinary tract was divided into 3 catagories,the minor,medium and the major.In minor and medium catagories (49 sides),the renogram on 37 sides changed from obstructive pattern (no excretory phase) to reduced excretion ones which slopped downward obviously on frusemide administration (dilated nonobstructed pattern).The renogram had no change on 12 sides.In the major catagory (17 sides),BPR changed from 23.8?3.5% preoperatively to 33.4?6.4% postoperatively ( P

Objective To investigate the inhibitory effect of immunosuppressive agent FRY720 on hepatocellular carcinoma Hepal-6. Methods Hepal-6 cells were cultured, and divided into 4 groups, namely control group and 0.1 μg/ml, 10 μg/ml, 100 μg/ml quality concentration groups. The cells were treated by the drugs for 24 to 48 hours respectively. The inhibitory rate of the cells was measured by MTT assay, and cell cycle and cell apoptotic rate were detected by flow cytometry (FCM). Results The ability of tumor cell growth were inhibited by FTY720 after 48 h. The maximal inhibition rate was 62.10 %, The apoptosis ratio was increased when FTY720 was 0.1-100 μg/ml, and it was 4.07 %, 8.16 %, 19.84 % respectively. FTY720 significantly prolonged cell G1 phase. Conclusion FTY720 could inhibit the growth of hepatocellular carcinoma, arrest the cell in G1 phase, and increase apoptosis.

Objective Little is known about the effects of antioxidant on the micturition function in diabetic cystopathy .In this study, we investigated the effects of antioxidant sulforaphane on bladder micturition function in diabetes mellitus ( DM)mice with bladder underactivity . Met hods We established DM models in mice by intraperitoneal injection of a single dose of streptozotocin (STZ)at 65 mg/kg and randomly divided them into three groups , sulforaphane treatment (n=10), vehicle treatment (n=10), and DM model (n=10), with another 10 normal healthy mice included as blank controls.At 24 weeks of the experiment, we obtained and analyzed such indexes of mice as the body weight , fasting blood glucose (FBG), 24-hour urine volume (24 h UV) and bladder wet weight ( BWW ) , results of cystometrography , and cystometric parameters including intercontraction interval ( ICI ) , maximum bladder pressure during micturition ( Pmax ) , maximum cystometric capacity (MCC), void volume (VV), post-void residual urine vol-ume (PVR) and residual urine rate (RUR). Results Compared with the blank controls , the DM models with bladder underactivity showed significantly increases in BWW ([67.96 ±2.35]mg), 24 h HU ([22.47 ±1.93]mL), MCC ([0.70 ±0.03]mL), VV (0[.23 ±0.01]mL), PVR ([0.49 ±0.02]mL), RUR ([70.10 ± 0.80]%), and ICI, but a remarkable decrease in Pmax .Sulforaphane treatment significantly reduced BWW ([576.9 ±2.41]mg), 24 h HU ([16.27 ±1.51] mL), MCC ([0.54 ±0.03]mL), PVR ([0.34 ±0.02]mL), RUR ([62.71 ±1.26]%), and ICI of the diabetic mice . Conclusion Sulforaphane could improve bladder micturition function in mice with STZ-induced DM , which might be related to its action mechanism of antioxidative stress damage .
