Objective To study the causes of congenital hypospadias fistula and the repair methods,summarize surgical experience,and improve the success rate of fistula repair.Method s From January 2001 to February 2011,33 cases of urinary fistula after hypospadias urethroplasty were collected,the average age being 6.2 years (3 to 13 years).A total of 38 fistula were found,17 with fistula diameter of less than 3 mm,16 with fistula diameter of 3 - 10 mm,5 greater than 10 mm.Ligation embedding method were used,Y-V flap coverage method,a continuous inverted fistula suture,Thiersch method,Denis-Browne method and the U shaped flap covering method were used for multi-urinary fistula repair.Among the 33 cases,successful repair was found in 30 cases,with normal urination during flollow- up,good penile appearance,the success rate being 90.9%.Results The causes of hypospadias fistula after surgery in children are:vascularized free when properly drawn,resulting in poor blood supply to the flap; urine drainage was not smooth,resulting in premature suture wounds soaked in urine,causing infection; distal urethral stricture,high pressure within the urethra during urination,causing anastomotic dehiscence; suture materials of poor quality; technical immaturity.Conclusions The repair of urinary fistula after hypospadias in children has a variety of surgical procedures,choice of which should be based on fistula location,size,quantity and local conditions.

This paper aims to establish a method for the determination of sulfur dioxide in sulfur fumigation Chinese herbs. Sample powder and hydrochloric acid solution were isolated by paraffin layer in order to avoid early reactions, with the generation of sulfur dioxide, headspace with airtight needle was used to transfer sulfur dioxide into gas chromatograph, and detected with thermal conductivity detector. The analytical performance was demonstrated by the analysis of 12 herbs, spiked at four concentration levels. In general, the recoveries ranging from 70% to 110%, with relative standard deviations (RSDs) within 15%, were obtained. The limit of detection (LOD) was below 10 mg x kg(-1). Standard addition can be used for low recovery samples. The method is simple, less time-consuming, specific and sensitive. Methods comparison revealed that gas chromatography is better than traditional titration in terms of method operability, accuracy and specificity, showing good application value.

Aim ToinvestigatewhethertheJAK2/STAT3 signaling pathway regulates prohibitin expres-sion to protect cardiomyocytes against hypoxia/reoxy-genation injury in hydrogen sulfide postconditioning. Methods Primaryculturedcardiomyocytesfromneo-natal rats were divided into 6 groups: control group ( Normal) , hypoxia/reoxygenation group ( H/R ) , hy-drogen sulfide postconditioning group ( NP) , hydrogen sulfide with AG490 group ( N + A ) , AG490 group ( AG) , DMSO group ( DMSO) . The survival percent-age of cardiomyocytes and the release of LDH were tested at pre-hypoxia and reoxygenation 2h. After reox-ygenation, cell apoptosis was detected by flow cytome-try. The expression of t-STAT3, p-SATAT3 and PHB were determined with Western blot analysis. Results No obvious changes were observed among the groups before hypoxia (P <0. 05). After reoxygenation 2h, compared with H/R group, NP group significantly im-proved the survival rate of cardiomyocytes ( P <0. 05 ) , inhibited the release of LDH and the myocardi-al apoptosis ( P <0. 05 ) , meanwhile up-regulated the p-STAT3 and PHB expression. However, AG490 abol-ished the cardioprotection offered by hydrogen sulfide postconditioning and the increase in p-STAT3 and PHB expression.Conclusion Hydrogensulfidepostcondi-tioning may protect cardiomyocytes against hypoxia/reoxygenation injury through the JAK2/STAT3 pathway upregulating the expression of prohibitin.

Objective To explore the causes for the bile duct injury in gallbladder bed and investigate its diagnosis and management. Methods The data of 37 cases of bile duct injury in the gallbladder bed after cholecystectomy between January 1988 and March 1998 were retrospectively analyzed. Results According to the operative records, 17 among the 37 cases had leakage from Luschka bile duct, 4 from the cholecystohepatic duct and 3 from the right lobular hepatic duct and its branches. The sources of the leakage were not identified in other 17 cases. The injured sites were sutured and drained or drained alone in 30 cases. The other 4 cases without drainage were percutaneously under the ultrasonographic guidance because of an intra abdominal bile collection. The remaining 3 cases were surgically treated again for aggravation of the illness in them. Conclusions During performance of cholecystectomy, surgeons should pay close attention to the bile duct in the gallbladder bed for its vulnerable position. Careful inspection of the gallbladder bed should be a routine procedure after the operation. Once the bile leakage was recognized in the gallbladder bed, intraoperative drainage must be performed.

OBJECTIVE:To provide reference for improving the quality of clinical pharmacy undergraduates in our university. METHODS:Considering about the practice problems of clinical pharmacy undergraduates in our university,pilot reform was con-ducted in the First Affiliated Hospital of our university in respects of teacher arrangement,department rotation assignment,assess-ment method. RESULTS:For new practice mode,in term of teacher arrangement,when the students were practicing in clinical pharmacy department,they were taught by clinical doctors and pharmacists;teacher training should be strengthened,and a variety of teaching methods was carried out. In term of department rotation assignment,to shorten the practice time of basic pharmacy de-partment,and increase the clinical pharmacy practice department and practice time;to integrate the content of clinical medicine and clinical pharmacy practice,and select clinical medical departments equipped with clinical pharmacists to practice. In term of assess-ment method,there were 3 aspects including clinical pharmacy practice skills assessment,drug-related theory examination and ba-sic situation assessment during internship. CONCLUSIONS:The new practice mode focuses on clinical pharmacy application skills training and students practical skills assessment,contributes to cultivate students'thinking of rational drug use and improves clini-cal practice skill of students. It is suitable for clinical pharmacy undergraduate internship of our university.

Objective To summarize the complication of clinical characteristics, factors causing misdiagnosis, and diagnosis of large intestine tuberculosis (LIT). Methods The data of twenty cases of LIT misdiagnosed preoperatively in our hospital were analyzed retrospectively. The difficulties of LIT diagnosis and management were studied and analyzed. Results Abdominal pain, mass, and the alteration of stool habit were the most common symptoms. LIT was most commonly confused with malignant tumor, Crohn's disease, and periappendicular abscess. Ten of 17 patients, who were performed exploratory laparotomy, were misdiagnosed as tumor or Crohn's disease. Most of our cases were not definitively diagnosed until the histopathologic examination after surgery. Three cases were diagnosed by other methods. Gastrointestinal X ray series, colonoscopy, endoscopic fine needle aspiration cytology(FNAC) and laparoscopic exploration may improve the diagnosis. Exploratory laparotomy with biopsy was the final procedure for diagnosis. Final diagnosis mainly depends on histology. Conclusions LIT lacks special clinical manifestations and has a high misdiagnosis rate. But if correct diagnosis is established, most patients can be cured and unnecessary exploratory laparotomy can be avoided. Six months antituberculosis treatment is effective for LIT whether the lesion is excised or not.
