ObjectiveTo evaluate the effect of lengthening the short-side albuginea of the bending penis by the allogeneic acellular dermal matrix ( Allo-ADM ) for the treatment of penile curvature.MethodsFrom Jun 2007 to Jun 2010,18 patients with penile curvature due to malformation of the albuginea cavernous body were treated.The age of the patients ranged from 15 to 26 years (mean,20 years).Twelve patients were married.The curvature degree ranged from 30° to 80° (mean,55°).There were 17cases of single curvature and 1 case of complex curvature.The grafts ( Allo-ADM ) of different sizes were sutured to the albuginea at the curvatus side of the penis according to the extent of penile curvature through a circumcision incision.The extent of penile curvature and complications were evaluated postoperatively.ResultsPenile curvature was corrected in all 18 patients after the operation.No infection,hematoma and abnormal erection occurred postoperatively. No erectile dysfunction and penile re-curvature was observed during the follow-up period of 3 to 24 months.ConclusionLengthening the short-side albuginea of the bending penis by Allo-ADM could be a safe and effective way to correct penile curvature.

Objective To analyze the curative effects of total knee arthroplasty(TKA)for severe genu varus combined with flexion deformity.Methods The clinical data of 25 patients(36 knees),who had undergone TKA for severe genu varus combined with flexion deformity from January 2005 to October 2010,were retrospectively analyzed.There were 7 males and 18 females,aged from 55 to 80 years(average 70.5 years).The primary diseases were osteoarthritis in 22 cases and rheumatoid arthritis in 3 cases.HSS knee score was used before and after the operation to assess the efficacy of the TKA.Results All of the patients were followed up for 4 to 9 years(average 6 years).The degree of flexion deformity was reduced from (21 ±63)°to(1.1 ±2.3)°;the degree of the varus decreased from(210 ±4.8)°to(175.6 ±2.1)°;range of motion of the knee joint increased from(70.5 ±20.5)°to(115.1 ±5.3)°;knee score augmen-ted from(33.2 ±10.5)to(90.7 ±8.5);function score added from(35.5 ±14.2)to(85.6 ±10.5);there were 21 cases(8 knees)rated as excellent,2(3 knees)as good and 2(3 knees)as fair,and the excel-lent and good rate was 86%.Most of the patients had normal force line of the knee joint,but 2 patients re-mained varus deformity of 5°~10°.Conclusion Satisfying outcome can be achieved by TKA in treating severe genu varus combined with flexion deformity of the knee.

Objective:To observe the clinical effect of endodontic therapy and full crown restoration in the treatment of cracked teeth. Methods:The trace and depth of 50 cracked teeth were carefully examined under root canal microscope.According to the depth and scope of the cracks,the cracked teeth were classficated into the degree of Ⅰ,Ⅱ and Ⅲ,treated endodontically and restored with full crown.Results:During 1 year follow-up,34 cases showed successful effect,5 progressive,1 1 failure.The general effectiveness rate was 78.0%.The effectiveness rate of group Ⅰ,Ⅱ and Ⅲ was 93.3%,82.1 % and 28.6% respectively.Group Ⅰand Ⅱ vs Ⅲ,P <0.05,Ⅰvs Ⅱ,P >0.05.Conclusion:The treatment effect of cracked teeth is closely related to the depth and scope of cracks.

Objective To establish a rat model of peritoneal bacterial infection after liver transplantation.Methods To construct a dark Agouti rat-to-Lewis(DA-to-LEW) rat model of liver transplantation.Peritoneal bacterial infection in the rats was induced by intraperitoneal injection of bacterial suspension.The liver function,blood gas,blood cell count and other indicators of the rat models were detected.Results There was a high mortality rate in rats with bacterial injection at day 5 after liver transplantation,therefore unfavorable for the following study.It waft better to inject the bacteria in an amount of 5×10~5 cfu/mL at day 3 after liver transplantation.The cumulative 7-day survival rate of those rats after infection reached up to 37.5%.The infection became increasingly severe,the general conditions were worsening,the rectal temperature was rising,the WBC count was increased,the pH was decreased,liver dysfunction was progressively increased,and metabolic acidosis occurred in the rats.Liver parenchymal damage was more pronounced than that of bile ductal injuries,and the rats died one after another at about 5 days after infection.Pathological examination of multiple organs showed that the main cause of death of the rats was liver damage,without accompanying lung and kidney damages.Conclusion The results of this study suggest that it is a successful method to establish a rat model of peritoneal bacterial infection after liver transplantation,and this model can be used in related experimental researches.

OBJECTIVE To investigate the risk factors of nosocomial infection among child tumor patients with post-surgery chemotherapy.METHODS A total of 312 child tumor cases with post-surgery chemotherapy in the pediatric ward during from Dec 2004 to Dec 2008 were retrospectively reviewed.And 16 variables such as age,diagnosis,white blood cell count and nosocomial infections were studied.The data were analyzed with the single factorial ?2 test and multifactorial Logistic-regression analysis.RESULTS The incidence of nosocomial infection was 27.56%.The length of hospitalization,the white blood cell count,the neutrophil cell count and the invasive operation were found as independent risk factors of the nosocomial infection.CONCLUSIONS Shortening the hospitalization length,increasing the white blood cell and the neutrophil cell count and avoiding the unnecessary invasive operation will decrease the nosocomial infection.

Objective To investigate the value of laparoscopy combined with esophagogastroscopy in the treatment of achalasia of the cardia. Methods Twenty-five patients with achalasia of the cardia between October 2003 and April 2006 in this department underwent the HellerDor operation under laparoscopy combined with esophagogastroscopy.Results A1l the operations were successfully accomplished.The operating time was 60~240 min(mean,107 min) and the intraoperative blood loss,5~60 ml(mean,22 ml).Intraoperative mucosal perforation was encountered in 4 patients.All the patients got out of bed for activities at 8 hours after operation,with first passage of flatus,removal of the gastric tube,and liquid diet intake at 1~3 days after operation(mean,1.5 days).The esophageal manometry showed the lower esophageal sphincter(LES) pressure had decreased to normal levels at 7 days after operation.The 24-hour ambulatory pH studies showed a high reflex index in 3 patients,but without symptoms.Upper gastrointestinal barium swallow showed the dilated esophagus had a 8~26 mm(mean,18 mm) decrease in diameter at 8 days after operation.The length of postoperative hospitalization was 8~11 days(mean,8.5 days).Follow-up for 1~30 months(mean,5.4 months) in all the patients showed 23 patients were asymptomatic and 2 had intermittent dysphagia.Conclusions Heller-Dor operation under laparoscopy combined with esophagogastroscopy has advantages of precise positioning,little invasion,less pain,and good effects,increasing the quality of operation as well as decreasing the incidence of complications.

Objective To explore the clinical value of domestic harmonic scalpel in laparoscopic cholecystectomy. Methods Modified laparoscopic cholecystectomy (LC) was performed in 36 cases under general anesthesia. The operation was completed by using domestic USI harmonic scalpel in 21 cases (USI Group) and by using imported harmonic scalpel in 15 cases (GEN Group). Results The operation was laparoscopically accomplished in both of the groups, without conversions to open surgery. Of the USI Group, the operating time was 42.6?7.5 min, the postoperative drainage was 34.3?14.0 ml, the length of postoperative hospitalization was 4.9?0.9 d, the speed for cutting cystic duct was 335.1?180.3 ?m/s, the speed for cutting cystic artery was 524.2?127.8 ?m/s, and the denaturalization width of cystic duct was 2 047.6?376.3 ?m. Of the GEN Group, the operating time was 47.0?9.0 min, the postoperative drainage was 38.0?3.9 ml, the length of postoperative hospitalization was 4.3?0.9 d, the speed for cutting cystic duct was 403.5?120.1 ?m/s, the speed for cutting cystic artery was 513.5?125.9 ?m/s, and the denaturalization width of cystic duct was 2 266.7?306.3 ?m. There was no differences in these parameters between the two groups ( P
