Objective To explore the indication,technique and complications of Snodgrass operation in hypospadias repairment.Methods From Sep.2005 to Nov.2006,22 boys from 2 to 18 years old with hypospadias were treated with Snodgrass modification.The procedure was performed in 16 patients as a primary repairment and in 6 patients as the 2-stage repairment.The entire length of the urethral plate was incised along the midline in primary repairment,and the skin flaps and residual urethral plate were incised in the 2-stage repairment.The length of neourethra was from 1 to 10 cm.The neourethra was tubularized over a F 6 or F 8 catheter.The urethral stent was removed in 10 to 14 days pos-toperatively.Results Of the 22 patients,18(81.8%) required no other surgery as the repairment provided a normal appearing penis(straight,terminal meatus, cosmetics) without complications.Fistul aoccurred in 4 patients(18.2%) and meatal stenosis in 1 patient.Conclusion Snodgrass operation creates a vertical slit-like neomeatus.The procedures restores good function and normal appearance to the penis.

Objective To investigate the effect of microRNA-1 (miR-1) on the fibrosis of cardiac fibroblasts induced by high glucose. Methods The primary cultured fibroblasts from 1-3 days old Sprague-Dawley (SD) rats, were randomly divided into 4 groups (n = 3): normal glucose + lentivector-vehicle (CON+Lv-Vehicle group), normal glucose + lentivector-miR-1 (CON+Lv-miR1 group), high glucose + lentivector-vehicle (HG+Lv-Vehicle group), high glucose + lentivector-miR-1 (HG+Lv-miR1 group). Fibroblasts were cultured in glucose concentration 5.5 mmol/L and 25 mmol/L DMEM culture, and were injected lentiviral vector carrying miR-1 silencer sequence or the same volume of lentiviral vector. After 12 hours, the medium was replaced with fresh complete medium. After 3 days when transfection efficiency was up to 90%, the cellular miR-1 content was detected by real-time reverse transcription-polymerase chain reaction (qRT-PCR). The secretion of collagen Ⅰ and Ⅲ were measured by enzyme linked immunosorbent assay (ELISA). Expression of collagen Ⅰ and Ⅲ, matrix metalloproteinase 2 and 9 (MMP-2, MMP-9), autophagy related protein LC3B-Ⅱ, P62/SQSTM1 and Cathepsin D were assessed by Western Blot. Results Compared with the CON+Lv-Vehicle group, the content of miRNA in the CON+Lv-miR1 group had no statistical significance. Compared with the CON+Lv-Vehicle group, high glucose increased the amount of miR-1 (2-ΔΔCt: 1.82±0.17 vs. 1.00±0.04), collagen Ⅰ and Ⅲ secretion (mg/L: 14.55±0.33 vs. 7.28±0.22, 157.50±13.22 vs. 61.25±8.54) and expression (gray value: 432.35±56.00 vs. 100.00±15.00, 320.35±47.00 vs. 100.00±15.00), the level of MMP-2, MMP-9 and the expression of autophagy related protein LC3B-Ⅱ and P62/SQSTM1 (gray value: 249.0±21.0 vs. 100.0±15.0, 142.3±20.0 vs. 100.0±16.0, 178±19 vs. 100±14, 378.3±20.0 vs. 100.0±15.0), decreased the expression of lysosomal associated protein Cathepsin D (gray value: 60±14 vs. 100±10), and the differences were statistically significant (all P < 0.01). Compared with the HG+Lv-Vehicle group, the amount of miR-1 in the HG+Lv-miR1 group was significantly decreased (2-ΔΔCt: 1.21±0.10 vs. 1.82±0.17), collagen Ⅰ and Ⅲ secretion (mg/L: 10.68±0.54 vs. 14.55±0.33, 87.25±13.55 vs. 157.50±13.22) and expression (gray value: 179.41±45.00 vs. 432.35±56.00, 173.41±50.00 vs. 320.35±47.00), the level of MMP-2, MMP-9 and the expression of autophagy related protein LC3B-Ⅱ and P62/SQSTM1 (gray value: 172.0±23.0 vs. 249.0±21.0, 90.0±17.0 vs. 142.3±20.0, 138±15 vs. 178±19, 265.0±17.0 vs. 378.3±20.0) in the HG+Lv-miR1 group were decreased and the expression of lysosomal associated protein Cathepsin D was higher (gray value: 110±17 vs. 60±14), and the differences were statistically significant (all P < 0.05). Conclusions The expression of miRNA-1 was up-regulated in cardiac fibroblasts cultured in high glucose, and miRNA-1 silencing inhibited cardiac fibroblast induced fibrosis in high glucose. The mechanism may be related to the recovery of autophagy flux, up-regulation of Cathepsin D expression and inhibition of collagen production.

OBJECTIVETo observe the clinical efficacy of transcutanclus electrical acupoint stimulation (TEAS) on prevention and treatment of orthodontic toothache and oral dysfunction.

METHODSA total of 85 patients of malocclusions in the preliminary diagnosis were randomly divided into a control group (20 cases), a psychological intervention group (22 cases), a medication group (20 cases) and a TEAS group (23 cases). Orthodontics treatment was given in all the groups. Patients in the control group received no further treatment; patients in the psychological intervention group received comprehensive psychological intervention, including cognitive education and music therapy; patients in the medication group received oral administration of ibuprofen; patients in the TEAS group received TEAS at Juliao (ST 3), Jiachengjiang (Extra) and auricular point Ya (LO1). The treatment was given twice a day, one in morning and one at night, for 7 days. The pain scores of orthodontic toothache and changes of oral dysfunction were observed in all groups.

RESULTS(1) At 5 time points from the 12th hour to the 4th day, the scores of spontaneous pain in TEAS group were lower than those in the control group (all P < 0.01); during the time points, the scores in TEAS group were lower than those in the psychological intervention group (P < 0.05, P < 0.01), which were similar to those in the medication group (all P > 0.05). (2) During the peak cycle of spontaneous toothache, the scores of irritation pain in TEAS group were significantly lower than those in the control group (all P < O.01), regardless of time-point statistics or general statistics; the scores of irritation pain in the TEAS group were also significantly lower than those in the psychological intervention group (all P < 0.01), which were similar to those in the medication group (all P > 0. 05). (3) Compared with control group, the grading of talking disorder in the remaining groups did not change significantly (P > 0.05). (4) Compared with control group, the grading of moderate-severe eating disorder in TEAS group was significantly reduced (P < O.05), which was not different from that in the medication group (P > 0.05). The differences of the grading of moderate-severe eating disorder were not significantly different between the psychological intervention group and control group (P > 0.05). (5) There were 3 cases of digestive system adverse reactions in the medication group.

CONCLUSIONTEAS can efficiently prevent orthodontic toothache and oral dysfunction, which is superior to psychological intervention and similar to medication. In addition, it can avoid possible side-effect of medication.
