Background:Oryz-Aspergillus Enzyme and Pancreatin Tablet is a double-deck digestive enzyme pellet containing Oryz-Aspergillus enzyme and pancreatin that has been widely used for treatment of functional dyspepsia (FD)in clinical practice. However,there is no randomized controlled trial focusing on the efficacy of this agent versus other drugs used for treatment of FD such as prokinetics and proton pump inhibitors (PPI). Aims:To compare the efficacy and safety among Oryz-Aspergillus Enzyme and Pancreatin Tablet,Domperidone Tablet and Esomeprazole Magnesium Enteric-coated Tablet, three drugs with different mechanisms of action on FD,in Chinese population. Methods:A total of 82 Helicobacter pylori-negative outpatients fulfilling the diagnostic criteria of FD in Rome Ⅲ were recruited from Nov. 2015 to Jun. 2016 at the First Affiliated Hospital of Zhejiang Chinese Medical University. These patients were randomly allocated into 3 groups,and received Oryz-Aspergillus Enzyme and Pancreatin Tablet (group A),Domperidone Tablet (group B)and Esomeprazole Magnesium Enteric-coated Tablet (group C)orally for 4 weeks,respectively. The improvement of dyspeptic symptoms and adverse events were observed and recorded. Results:After 4 weeks treatment,the overall efficacies for global symptoms in group A,group B and group C were 93. 1%,88. 9% and 69. 2%,respectively,statistically significant difference was existed among the three groups (P < 0. 05). Domperidone Tablet was effective for postprandial fullness and early satiety;Esomeprazole Magnesium Enteric-coated Tablet was sensitive for epigastric pain,epigastric burning,and belching and regurgitation;the efficacies of Oryz-Aspergillus Enzyme and Pancreatin Tablet for all five dyspeptic symptoms were in between. No adverse events were observed during treatment course. Conclusions:Digestive enzymes,prokinetics and PPI have different sensitive symptoms and optimal indications for treatment of FD. The overall efficacy of Oryz-Aspergillus Enzyme and Pancreatin Tablet is superior to that of prokinetics and PPI.

OBJECTIVE: Complication incidence of urinary fistula which frequently occurs following renal transplantation is 3%-10%. Thus, poor processing may cause loss of transplanted kidney. This study was designed to retrospectively analyze urinary fistula following renal transplantation and to summarize the processing experience. METHODS: A total of 27 out of 1 203 patients with urinary fistula following renal transplantation (16 males and female 11 and mean age of 43 years) were collected from Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA from December 2000 to March 2009. Totally, 26 patients accepted donor kidney from corpse, and 1 from living body. All patients were treated with expectant treatment (n=17) including inserting 18Fr Foley catheter alone and draining from the native drainage channel of operative site (n=12) and inserting a ureteral stent (single-J) by cystoscope retrograde approach and inserting 18Fr Foley catheter into the bladder (n=5); exploring operation (n=10) including anastomosing ureter and bladder and placing ureteral stent (n=5) and anastomosing ureter and ureter of recipient and placing ureteral stent (n=5); pedicled omentum grafts to cover and surround stoma after suturing (n=6). RESULTS: Only 1 case was failed because kidney vain was injured in the second operation and the kidney was resected. Another 26 cases were cured. Within the 3 month to 7 years follow-up, the urinary fistulas did not relapse, no stegnosis or hydronephrosis, no urinary tract infection and renal function were normal. CONCLUSION: Rapid diagnosis and treatment for urinary fistulas after renal transplantation is imperative. First mostly patients may be cured by expectant treatment. If not then perform exploratory operation. Using peclicled omentum grafts to cover and surround stoma after suturing for complex urinary fistulas can raise achievement ratio of operation.

Objective To investigate the security and result of operation of one side polycystic kidney removal and homonymy kidney transplantation simultaneously for giga-polycystic kidney di-sease of terminal stage. Methods Forty-five patients with polycystic kidney of transplantation were retrospectively analyzed. The patients were divided into 2 groups. Patients of group A (n=23) under-went resection of the cystic kidney by extraperitoneum and the other 22 patients(group B) didn't re-move the cystic kidney. The data including average length of hospital stay, variance of blood pressure, lessen of abdominal circumference, lung capacity, total lung capacity, FEV1.0/FVC, incidence rate of delayed graft function (DGF) and 1 year patient/kidney survival rate of the 2 groups were compared. Results The average length of post-operative hospital stay of group A was (14.5±2.6)d,lessen of blood pressure was (30.0±0.7/13.34±8.4)mm Hg, lessen of abdominal circumference was (11.0+ 6. 3) cm, lung capacity increased (1.4±0.3)L, total lung capacity increased (2.0±1.0)L, FEV1.0/ FVC increased (5.3±1.0) %, the incidence rate of DGF was 8.7% (2/23), 1 year patient/ kidney survival rate was 100.0%/95.7%. The average length of post-operative hospital stay of group B was (28.45±7.9)d,lessen of blood pressure was (3.9±11.2/2.9±12. 0)ram Hg, lessen of abdominal circumference was (3.3±2.2)cm, lung capacity increased (0.44±0.3)L, total lung capacity increased (0.8±0.2) L, FEV1.0/FVC increased (2.0±0.9)%, the incidence rate of DGF was 9.1%(2/22), 1 year patient/kidney survival rate was 100.0%/95.5%. There were no significant differences of the incidence rate of DGF and 1 year patient/kidney survival rate between the 2 groups. While there were significant differences of the other data between the 2 groups(P<0.05). Conclusions It is safe and convenient for one side polycystic kidney removal and homonyrny kidney transplantation simultaneous-ly for giga-polycystic kidney disease of terminal stage. The procedure could be applied to the patients of graveness complication or giga-polycystie kidney hampering operation of transplantation.

Objective To assess the safety and efficacy of balloon dilation of pulmonary valve stenosis with 10 F domestic balloon catheter in children ≥ 10 kg. Methods From May 2009 to June 2014, eighty-three consecutive children with weight ≥ 10 kg and age of (4.5±2.8)(ranged from 1-12) years underwent percutaneous balloon pulmonary valvoloplasty(PBPV) with 10 F domestic balloon catheter. Indication for treatment, procedural details, catheterization data, complication rate, peak-to-peak systolic gradient across the valve and pulmonary insufficiency on echocardiography were respectively analyzed. Forty-four patients were followed up 6-44 months after procedure. Results All procedures were completed successfully. The peak-to-peak systolic gradient across the pulmonary valve decreased from (67.7±26.2) mmHg to (15.4±11.6) mmHg (P < 0.01) immediately after PBPV. Two patients developed reactive infundibular spasm after dilation. They were relieved at 6 months post PBPV. No patient had severe pulmonary insufficiency, tricuspid regurgitation or reintervetion. Conclusions PBPV with 10 F domestic balloon catheter in children with weight≥10 kg is a safe and effective method.

AIM: To investigate the role of chloride channels in the apoptosis of human poorly differentiated nasopharyngeal carcinoma CNE-2Z cells induced by arsenic trioxide (As2O3).METHODS: The apoptotic rates of CNE-2Z cells induced by As2O3 for 24 h or 48 h were monitored by flow cytometry.The technique of whole-cell patch clamp was used to record the currents activated by As2O3 in the CNE-2Z cells.The inhibition of As2O3-induced apoptosis by chloride channel blocker DIDS in the CNE-2Z cells was analyzed by flow cytometry.RESULTS: As2O3 at 5 μmol/L induced apoptosis of CNE-2Z cells in time-dependent manner.The currents with outward rectification were activated when the cells were exposed to 5 μmol/L As2O3.No obvious time-and voltage-dependent inactivation of the currents was observed.The reverse potential of the currents was close to the equilibrium potential for chloride.The activated currents were inhibited by the chloride channel blockers NPPB and DIDS.The 47% hypertonic solution inhibited the activated currents completely.Chloride channel blocker DIDS inhibited the apoptosis of CNE-2Z cells induced by As2O3.CONCLUSION: As2O3 activates volume-sensitive chloride channels, and chloride channels may play an important role in the apoptosis of CNE-2Z cells induced by As2O3.

Objective To discuss the treatment of urethral stricture after hypospadias reDair.Methods Thirty-seven cases of urethral stricture after hypospadias repair from 1999 to 2006 were ret-rospectively analyzed. Of 37 patients,the stricture was located at the distal end of urethra in 7 cases.There were 3 1 cases with anastomotic stricture.There was 1 case with distal urethral stricture and anastomotic structure.There were 1 3 patients with the simple urethral stricture and the complicated 24 cases.Of 13 simple urethral stricture patients,4 patients were repaired with urethro-meatomy,6 patients with shelf operation and 3 patients with transurethral holmium laser urethrotomy.Eight Pa-tients with complicated urethral fistula,6 patients with urethral diverticula,4 patients with phallo-campsis and 6 patients with many times of postoperative urethral stricture were repaired with shelf op-eration or penis skin flap or septum of scrotum skin flaps urethroplasty. Results The simple stric-tures of 1 2 patients were cured by stage 1 operation,the other one cured after second surgery.Of 8 patients with fistula,7 were cured at stage 1,the other one was cured at the stage 2.Of 6 patients with diverticulum,all were cured at stage 1.Of 4 patients with phallocampsis,3 cases were cured at stage 1,the other one was cured at the stage 2.Of 6 patients with recurrent strictures,all were cured at stage 1.A1l patients were followed up 1 2 to 24 months.The micturition was without difficuItv at stand position. Conclusions Urethral stricture is one of the most common complications after hypos-padias repair.The simple urethral stricture could be repaired with urethro-meatomy or sheIf operation or transurethral holmium laser urethrotomy.The complicated urethral stricture could be reDaired with shelf operation or penis skin flaps or septum of scrotum skin flaps urethroplasty and overjetted with dortos of scrotum flaps.

Objective To compare the accuracy of blood volume perfusion imaging (perfusion CT)with contrast enhanced 64-slice spiral computed tomography (CECT) in the evaluation of gross tumor volume (GTV) and clinical target volume (CTV) using rabbits with VX2 brain tumor. Methods Perfusion CT and CECT were performed in 20 rabbits with VX2 brain tumor. The GTV and CTV calculated with the maximal and minimal diameter of each tumor in the blood volume (BV) maps and CECT were measured and compared to those in pathological specimens. Results The mean value of the maximal and minimal diameter of GTV was (8.19 ± 2. 29) mm and (4.83 ± 1.31) mm in pathological specimens, (11.98 ±3.29) mmand (7.03±1.82) mm in BV maps, while (6.36±3.85) mm and (3.17±1.93) mm in CECT images, which were significantly different (pathological specimen vs. BV map, t = 7. 17,P =0. 000;pathological specimen vs. CECT, t = 8.37, P = 0. 000, respectively). The mean value of the maximal and minimal diameter of CTV in pathologic specimens was (12.87 ± 3.74) mm and (7.71 ± 2. 15) mm, which was significantly different from that of GTV and CTV in CECT (t = - 3. 18, P = 0. 005 and t = - 4. 24, P =0. 000;t= -11.59,P=0.000 and t= -9.39,P=0.000), while similar with that of GTV in BV maps (t = - 1.95,P = 0. 067; t = - 2. 06, P = 0. 054). For CECT, the margin from GTV to CTV was 81.83% ±40.33% for the maximal diameter and 276.73% ± 131.46% for the minimal. While for BV maps, the margin was 7.93% ± 17. 84% and 12.52% ± 27. 83%, which was significant different from that for CECT images (t=7.36,P=0. 000 and t= -8.78,P=0.000). Conclusions Compared with CECT, the BV map from 64-slice spiral CT peffusion imaging might have higher accuracy in target volume delineation for brain tumor.

Objective To determine whether an increased number of transrectal biopsy cores improves the accuracy of biopsy Gleason score. Methods This study reviewed a total of 86 patients who were diagnosed as prostate cancer by transrectal needle biopsy and subsequently underwent radical prostatectomy (RP) without neoadjuvant therapy.The rate of grading concordance between biopsy and RP specimens was analyzed by dividing these patients into 2 groups according to the biopsy cores:group A,46 patients who underwent transrectai biopsy sampling of 6 cores,and group B,40 patients who underwent biopsy sampling of 13 cores. Results The concordance between prostate biopsy and radical prostatectomy Gleason score was 65.0%and 34.8% for 13 core and 6 core biopsy,respectirely (P<0.05).Furthermore,these findings tended to be more prominent as the biopsy Gleason score was lower.Multivariate analysis identified the number of biopsy cores and percent of positive biopsy cores as independent predictors of accurate Gleason grading regardless of other parameters examined in this study. Conclusion Extended needle biopsy may increases the accuracy of biopsy Gleason score for assessing final prostate cancer grade.

Objective To analyze the effect of antibiotic treatment on prostate specific antigen (PSA) derivations in patients with and without prostate cancer and to further determine if the changes of PSA values after antibiotic treatment could help to exclude inflammation in the differential diagnosis of an abnormal PSA.MethodsA total of 100 patients with lower urinary tract symptoms,a PSA level of 4 to 10 μg/L,free PSA/total PSA (fPSA/tPSA) ratio < 0.25,and a negative digital rectal examination and transrectal ultrasonography were enrolled in this study.All patients received 500 mg of ciprofloxacin twice a day for 3 weeks.Free and total PSA values were measured before and after antibiotic treatment.All the patients were then scheduled for 12-core prostate biopsy.Results The mean tPSA value was (6.5 ± 1.2) and (5.1 ± 1.2) μg/L respectively before and after antibiotic treatment ( P < 0.01 ).Ninety-one patients (91.0%) showed tPSA reduction after antibiotic therapy,of which 13 ( 14.3% ) had prostate cancer on biopsy.In 17 cases (18.7%) post-treatment tPSA was less than 4 μg/L.Three of the 17 cases (17.6%)had prostate cancer on biopsy.In 6 of the 100 men post-treatment tPSA was between 4 and 10 μg/L and the fPSA/tPSA ratio was above 0.25.One of these cases had prostate cancer on biopsy.Seven cases had a >50% reduction in PSA levels with no positive biopsy results.Although mean total PSA and PSAD decreased after treatment in both groups,the reductions within these parameters were not significantly different between patients with and without prostate cancer (P > 0.05).Furthermore,no differences emerged in terms of the changes of other PSA derivations including fPSA and fPSA/tPSA ( P > 0.05 ).ConclusionsThe PSA levels may change with long-term antibiotic treatment in patients with elevated PSA values.A decrease in PSA after antibiotic treatment does not rule out the presence of prostate cancer even if PSA decreases to a normal level.But a > 50% reduction in PSA levels may be associated with a decreasing risk of prostate cancer,which may allow a postponement of prostate biopsy in selected patients.
