Objective To assess the safety and efficacy of the transohturator tape (TOT) for surgical treatment of female stress urinary incontinence (SUI). Methods Clinical data of 206 TOT procedures for female urinary incontinence from Jan 2007 to Dec 2009 was retrospectively analyzed.Thirty-one women were identified as having mixed stress urinary incontinence.The mean age was 54.29 years(range,32-81 years),themean disease coursewas 10.31 years (range,1-40 years),and the mean follow-up time was 17.3 months (range,3-39 months).Therapeutic effects were assessed by Grouts-Blaivas outcome score.The results of the operation,complications and changes of urodynarnics were observed. Results The TOT operations were conducted under local anesthesia.The mean operative time was 23.9 min (range,16-35 min),Mean blood loss was 17.8 ml(range,15-30 ml).Short-term complications were as follows:thigh pain 14.08%,dysuria 5.83%,urinary posture change 0.97% and urinary retention 0.49%.The long-term complication rate was 0.97%,including vaginal wall defect and tape exposure in one case:the burr of tape exposure and sex life influence in one case.Long-term symptoms disappeared completely in 202 cases.The cure rate was 98.06%,and the rate of satisfaction was 100%. Conclusions Our results demonstrate that TOT procedure is a minimally invasive,safe and effective surgical treatment for stress urinary incontinence.

Objective To analyze the efficacy and safety of suprapubic arc sling (SPARC) and transobturater vaginal tape (TOT) for female stress urinary incontinence (SUI). Methods A retrospective study was conducted on 275 women ( 139 in TOT group and 136 in SPARC group) in our institute from September 2008 to January 2011.We had compared the complications of the two groups.All the patient's ICI-Q-SF scores and PISQ-12 scores were collected.We compared the pre- and post-operative Qmax and PVR to find out if SPARC or TOT tap cause bladder outlet obstruction (BOO). Results The operative time was 25.1 ± 3.3 min for TOT and 34.8 ± 5.6 min for SPARC.There was statistical difference between the two groups in the aspects of operative time (P =0.00).The improvements of average symptom and QOL scores in patients undergoing TOT and SPARC were statistically significant (P =0.00).The improvements of the PISQ-12 scores in the two groups were statistically significant (P <0.05 ) as well.There was no significant difference (P > 0.05 ) in the total cure rate of TOT and SPARC.The complications post SPARC and TOT were low.In the TOT group,the Qmax changed from 30.2 ± 8.7 ml/s per-operatively to 24.9 ± 8.6 ml/s post-operatively in a week.PVR changed from 1.6 ± 4.2 ml pre-operatively to 3.2 ± 6.5 ml post-operatively in a week.In the SPARC group,the Qmax changed from 31.7 ±9.4 ml/s pre-operatively to 26.9 ± 8.9 ml/s post-operatively in a week.PVR changed from 1.4 ± 3.7 ml pre-operatively to 3.5 ± 6.3 ml postoperatively in a week.All the changes were significant ( P < 0.05 ).And in the SPARC group,the Qmax changed from 31.2 ± 10.0 ml/s pre-operatively to 26.2 ± 9.1 ml/s post-operatively; the PVR changed from 1.8 ± 3.2 ml pre-operatively to 4.7 ± 8.8 ml post-operatively (P < 0.05). Conclusions Both the TOT sling and the SPARC sling have high cure rates for SUI.But the retropubic sling may lead to BOO and other complications,so the transobturate sling is a better treatment option for SUI.

AIM: To discuss the establishment of immediate diabetic keratopathy animal model of C57BL/6 mouse induced by ahigh-fat and high-glucose diet.
METHODS: Diabetes mellitus was induced by a high-fat and high-glucose diet in C57BL/6 mouse. 1% rose bengal was stained on the cornea to examine the integrality of the corneal epithelium at 2 ~ 12mo after completion of the model. Corneal epithelial wound healing was observed using a vivo epithelial debridement model which was dyed by sodium fluorescein. Corneal morphology histology was examined by pathological methods.
RESULTS: The high-fat and high-glucose diet C57BL/6 mouse in 2mo had showed general symptoms of diabetes: polydipsia, polyphagia, polyuria, weight loss etc. The model had a steady-state high glucose (≥18mmol/L), also the weight was lower compared with normal control mouse. 1% rose bengal corneal staining had dot coloring at 2mo after completion of the model, the stained area and extent were gradually increased with the extension of the duration of diabetes, almost all the cornea was stained at 12mo after completion of the
model. With the passage of time into a mold, the cornea epithelial healing time become longer: 2mo was about 40h;3mo was about 120h; 4, 6, 12mo was about 144h;the coloboma were gradually increased at 12mo after completion of the model, then the area was reduced gradually until complete healing, the time was 96~120h, showed repeating phenomenon.
CONCLUSION: The mouse were induced by high-fat and high-glucose diet can be used as animal models of diabetic keratopathy: the damage of epithelium for corneal and delay healing on epithelium and other symptoms.

This paper aimed to study the effect nitrogen supplying on biomass accumulation and root respiration dynamic change of Glycyrrhiza uralensis and reveal the metabolic pathway of root respiration impact the biomass accumulating of G. uralensis. Six groups of one-year-old G. uralensis were fertilized with total nutrition containing various nitrogen concentration (0, 0.5, 1, 2, 4, 8 mmol x L(-1)) every week. At the end of every month, from June to October, the volume respiration rate and biomass of different classes of root samples were determined, and the correlation between root respiration and biomass was analyzed. The results indicated a negative correlation between volume respiration rate and biomass, nitrogen supply significantly affected both root respiration and biomass of G. uralensis by reducing root respiration and increasing root biomass. Under 8 mmol x L(-1) nitrogen supplying, there existed the optimal inhibition of root respiration, which has increased biomass of G. uralensis.
