Objective To investigate the clinical curative effects of duloxetine combined with thioctic acid on diabetic painful peripheral neuropathy. Methods Sixty-two patients with diabetic painful peripheral neuropathy were divided into three groups by random digits table: group A(22 patients, duloxetine combined with thioctic acid group), group B (20 patients,duloxetine group) and group C (20 patients,thioctic acid group). The other treatments were same. All patients were treated for six weeks. The pain remission level and nerve conductive velocity were compared among three groups. Results The pain level in three groups was significantly alleviated after treatment (P ＜ 0.01 ). The general effective rate was 86.4%(19/22),70.0% (14/20) and 50.0% (10/20) in group A,group B and group C,respectively (P ＜ 0.05). Visual analogue scales (VAS) in group A was significantly lower than that in group B and group C from the second week after treatment (P ＜ 0.05 ). Nerve conductive velocity was improved in both group A and group C after treatment (P＜0.01),but there was no significant difference between two groups (P＞0.05). In group B,compared with that before treatment,nerve conductive velocity had no significantly improved after treatment (P＞ 0.05). Conclusion Duloxetine combined with thioctic acid can enhance the clinical curative effects on diabetic painful peripheral neuropathy.

Objective To evaluate bulbourethral sling procedure in the treatment of post prostatectomy incontinence. Methods 5 patients with post prostatectomy incontinence underwent the bulbourethral sling procedure.Preoperatively 1 patient was completely incontinent and 4 patients required a mean of 3.5 pads per day.The mean duration of incontinence was 4.5 years. A sling tension of a mean of 500 g was used to correct incontinence. Results 4 patients have been completely dry,whereas postoperative difficulty in voiding occurred in the other patient and was corrected by subsequent transurethral bladder neck revision resulting in free passage of urine and continence. Conclusions The bulbourethral sling procedure is an effective means in the treatment of post prostatectomy incontinence.

Objective To study the effect of poly- DL- lactic acid (PDLLA) absorbable membrane on preventing adhesion after repair of peripheral nerve injury. Methods 60 SD rats were divided into 2 groups randomly: the suturing+ PDLLA group (experimental group) and the purely suturing group (contrast group), with 30 rats in each group. Their sciatic nerves were cut off and then sutured microsurgically. In the experimental group, the anastomotic stoma was encapsulated with PDLLA membrane; in the contrast group, there was no such a treatment. We conducted gross observations and histological examinations at 2, 4, 8, 12, and 16 weeks after operation, neural electrophysiological examinations at 12 and 16 weeks after operation, and image analysis by computer at 16 weeks after operation. Results The scar proliferation and adhesion near the anastomotic stoma in the experimental group were less extensive than those in the contrast group; regenerative nerve fibers grew more straight and orderly manner. Electrophysiological examinations and image analyses by computer also showed that the experimental group achieved better results than the contrast group. Conclusion Poly- DL- lactic acid (PDLLA) absorbable membrane can prevent scar proliferation and adhesion after repair of peripheral nerve and promote nerve functional recovery effectively.

Objective To evaluate the efficacy of transpubie access using pedicle tabularized la-bial urethroplasty for urethral reconstruction in female patients with urethral strictures associated with urethrovaginal fistulas.Methods Eight cases of urethral strictures were treated using pedicle labial skin flaps for urethral reconstructions.All cases were the mid-urethral strictures associated with ure-throvaginal fistulas.A single face pedicle flap was obtained from the labia minus or majus in 5 women,and double face pedicle labial flaps were used in 3 patients.Results There were no serious complica-tions.Two patients complained of dysuria symptoms for 2 weeks and one patient experienced stress incontinence which resolved after 4 weeks.The patients were followed up for 6 to 130 months (mean 52) postoperatively.All patients had normal micturition following catheter removal with urinary peak flow greater than 15 ml/s(17.4-42.0 ml/s).Conclusion Pedicle labial urethroplasty might be a reliable technique for the management of complex urethral strictures associated with urethrovaginal fis-tulas.

Objective This study was to discuss various operative approaches for the repair complicated posterior urethral strictures. Methods 34 patients with posterior urethral strictures and associated ure-throrectal fistulas (URFs) were reviewed. The etiology of urethral strictures and fistula was due to pelvic fracture in 26 patients, iatrogenic in 6 cases and fall injury in the remaining 2 cases. The patients were treated by using a simple perineal approach (4 patients), a transperineal inferior pubectomy approach (21 patients) and combined abdominal transpubic perineal approach (9 patients) and URF repair and anastomotic urethroplasty were performed simultaneously in all cases. Results One-stage repair was successful in four patients (100%) using a simple perineal approach, in 19 of 21 (90. 48%) using the transperineal-inferior pubectomy approach and 7 of 9 (77. 78%) using the transpubic-perineal approach. Of the 34 patients, recurrent urethral strictures developed in two cases, recurrent URFs developd in two patients. Conclusions Surgical approaches for the special complex urethral strictures should be based on the location of the URF, its etiology and length of the urethral strictures, as well as a history of previous repairs. The transperineal-inferior pubic approach may be appropriate as a first-line procedure.

The glycoproteins in the biological sample are low abundance and are susceptible to be inhibited and interfered by other non-glycoproteins.An enrichment step is usually required before the glycoprotein analysis, but the operation steps of conventional solid-phase-based glycoprotein enrichment methods are difficult to be compatible with the most classical enzyme-linked immune sorbent assay (ELISA) technique.In this study, a novel water-soluble dendrimer based boronic acid capture (DBC) material was developed using PAMAM 4.0 as the carrier and boronic acid as the affinity group.The method was applied to the detection of glycoproteins in human liver microsomes using ELISA.In this study, the DBC enrichment conditions were optimized by model glycoprotein, and then its sensitivity and anti-interference ability were investigated.This method was applied to the enrichment of glycoproteinsin human liver microsomal.The results showed that the enrichment selectivity of DBC for glycoprotein could be up to 100000 folds, and the enrichment signal of glycoprotein could be increased by 100 times.Therefore, the ELISA method using DBC as a novel enrichment material for glycoprotein had high sensitivity and selectivity in detection of biological samples with only one simple incubation step, which was useful for glycoproteins researches.

s:Objective To study the effect of Cichorii Extract(CE)N2 on quail with hyperuricemia and hypertriglyceridemia.Methods Quail models were established by feeding of yeast.Effect of CE N2 on biochemical parameters such as serum uric acid,triglyceride,nitric oxide(NO),xanthine oxidase(XOD),etc.were observed dynamically.Results As compared with the control group,CE N2 in three different dosages decreased serum uric acid,triglyceride and NO;CE N2 in high and low dosage could also lower the serum activity of XOD.Conclusion CE N2 can lower serum uric acid and triglycercide levels in quails with hyperuricemia and hypertriglyceridemia.

Objective To study the value of flexible cystoscopy in diagnosing posterior urethral strictures resulting from pelvic fracture and the pain score of the examination. Methods Between 2014 and 2015, 120 male patients with pelvic fracture urethral distraction defect were evaluated by cystoscopy before surgery. In this study, flexible cystoscopy was used in 87 patients, 33 patients received conventional rigid cystoscopy. The cystoscopy was introduced into the posterior urethra and the area was evaluated for the length of the proximal urethra and any possible fistulas, false passages, calculi or displacement of the posterior urethra. The patient’s pain feeling was recorded during the examination, 24 hrs after cystoscopy examination. The pain feeling result was achieved by visual analogue pain scale. Results Severe allergic reaction or obvious discomfort did not occur in any patients after cystoscopy. By comparing the data obtained from lfexible cystoscopy to those from conventional urethrography, the rate of detection in other abnormalities was higher in lfexible cystoscopy than in conventional urethrography. 21, 5, 7 and 5 patients were detected with calculus, posterior urethral structure damage, false passage and ifstula respectively. In comparison, the abnormalities were only observed in 3, 2, 3 and 1 patients respectively through conventional urethrography imaging. However, the pain feeling of the flexible cystoscopy is better than the convenional rigid cystoscopy. The statistical difference was found in the pain feeling score during the examination and later after the examination. Conclusions Flexible cystoscopy is a safe and valuable procedure in the evaluation of the posterior urethra in patients with pelvic fracture urethral distraction defect before surgery.

Objective To study the application of androgens,AMH for female infertility diagnosis value.Methods Used chemiluminescence to detect androgen testosterone (To),androstenedione (AND),17 (HS)To hydrogen sulfate therapy (17HS),sex hormone binding globulin (SHG)and resistance To seedling le’s hormone (anti-Mullerian hormone,AMH)of 258 cases of patients with female infertility.According to the reason of infertility,female infertility patients were divided into observation group (158 cases of endocrine infertility)and control group (100 cases of tubal factor infertility)and two groups of data had statistical analysis with t test.Used Pearman’s correlation method to analyse the relationship between serum AMH level and AND,SHG in patients wirh female infertility.and used ROC curve to evaluate efficiency of AND and AMH to the diagnosis of female infertility.Results ①The indicators To observation group AND control group,AND,AMH and SHG were (1.25±0.41 vs 0.25±0.15)nmol/L,(4.9±0.62 vs 1.80±0.51)nmol/L,(13.6±3.5 vs 6.4±1.81)ng/ml and (64.2±32.1 vs 89.3±30.2)nmol/L,respectively.Compared with the control group,observation group To,AND and AMH were significantly higher than the control group (t=13.02,11.36,9.35,P values<0.01),but SHG was significantly low-wer than thecontrol group(t=7.35,P<0.01).②Between the biology to produce ets (AMH:7.63~10.1 ng/ml,AND:0.3~3.3 ng/ml,17 HS:18~144μg/dl,SHG:80~560 nmol/L)as the standard,in the observation group:17 HS increased 17.7%,AND increased 72.2%,AMH increased 87.9% and SHG 51.2% reduction.③AMH level and the AND existed positive correlation (r=0.579,P<0.05),negatively correlated with SHG (r=0.763,P<0.05).④AMH,AND and SHG diagnosis of infertility area under the ROC curve (AUC),were 0.921,0.863 and 0.736 respectively,best cutoff value were11.26 ng/ml,4.62 nmol/L and 32.62 ng/ml respectively,and sensitivity of 89.7%,72.9% and 59.6%.Specific degrees were 86.2%,86.2% and 75.6% respectively,and accuracy of 87.1%,87.1% and 81.6%.Jointed inspection of AND,AMH and SHG in the diagnosis of infertility,the sensitivity of the specific degree were 96.3% and 90.2% respectively.Conclusion It showed that AMH,AND and SHG have diagnostic value of internal secretory infertility with ROC curve analysis.De-tection of combined AMH,AND and SHG is more meaningful to the early diagnosis and treatment of infertility.
