[Objective]To discuss the significance of tissue repairing and functional reconstruction in treatment of extremity malignant tumors by allogeneic bone graft and replanting devitalized bone after malignant bone tumor resection. [Method]A retrospective study of 56 patients with malignant bone tumor was conducted, including 35 male patients and 21 female patients. The age was between 9 and 60, with an average of 18.Tumor in 9 cases was in the proximal hunerus, 30 in the distal femur, and 17 in the proximal cnemis.Thirty-two cases were osteogenic sarcoma,17 cases were chondroma sarcomatosum,3 cases were maligant giant cell tumor of bone and 4 cases were metastatic.Soft tissue was repaired and extremity function was reconstructed by adopting allogeneic bone graft and replanting devitalized bone. Extremity functions, bone healing conditions, and complication were estimated according to Mankin metheds.[Result]Among these 56 patients,results in 20(35.7%) were excellent,11(19.6%) were good,8(14.3%) were fair,17 (30%) were poor. The satisfactory rate was 70%.Thirty-eight patients survived for two years without tumor.Thirty patients survived for 5 years with the survival rate of 55%. Except local relapsed, the major complications were infection (4 cases), fracture (3 cases),collapse of articular facet (1 cases), and arthrocleisis (5 cases),with the infection rate of 7%.No internal fixation was broken.[Conclusion]For extremity malignant tumor, effective tissue repairing and functional reconstruction not only offer a limb-sparing effect, but also keep the limb in good function. This is an effective method for bone malignant tumor.

Adult onset Still's disease is a rare inflammatory disease characterized by spiking fevers, arthritis/ arthralgias, typical salmon-colored bumpy rash, pharyngalgia, myalgia and possible involvement of visceral organs. The diagnosis is exclusively based on clinical symptoms, according to the criteria, after the exclusion of well-known infectious, neoplastic, or other autoimmune/autoinflammatory disorders. This report includes one case of adult onset Still's disease with the initial symptom of pharyngalgia.

Epidermnoid cysts are henign, cutaneous cysts which commonly occur on face, neck and trunk. Retroauricular epidermoid cyst is rare reported which should be differentiated from auricle pseudocyst, lipoma, steatocystoma and fibroma. The hitopathological examination is a gold standard of diagnosis. Surgery of complete excision is the first choice of treatment methods.

Thirty-two patients with ureter carcinoma underwent single-docking robot-assisted nephroureterectomy in rectus rectilinear cannula placement in our hospital. The advantages include lower surgical difficulty, shorter operation time, less surgical bleeding and damage. This surgical method is a safe and effective minimally invasive treatment for ureter carcinoma.

Objective To Analyze the clinical outcomes of pediatric liver transplantation (LT) for liver-based metabolic disorders.Methods We conducted a retrospective analysis on 42 pediatric patients with liver-based metabolic disorders from June 2013 to March 2017,and analyzed the pediatric end stage liver disease model (PELD),growth and development,type of transplant,postoperative complications and prognosis of patients.Results There were 42 children with liver-based metabolic disorders (15.56%) out of all the 270 children who underwent LT.The median age was 51.0 months (range,3.4-160.9 months).Of the 42 children,19 received living donor liver transplantation (LDLT),18 cases received deceased donor liver transplantation (DDLT) and 5 cases received domino liver transplantation.1-,2-and 3-year cumulative survival rate of 42 recipients was 97.7%,93.6% and 93.6%,and that of the grafts was 95.3%,91.4% and 91.4%,respectively.As compared with the 194 children with biliary atresia who underwent LT,significant difference was found in PELD and weight Z-score between the two groups.Conclusion Liver transplantation is a valuable option for children with metabolic disorders,and it has gained a better prognosis.

Objective To determine the prevalence and risk factors of Epstein-Barr virus (EBV) infection after pediatric liver transplantation for patients with biliary atresia. Methods Clinical data of 65 pediatric patients with biliary atresia, who underwent liver transplantation, were retrospectively analyzed. Patients were divided into EBV infection group
(n=30) and non-EBV infection group (n=35). The univariate analysis was used to analyse the preoperative, intraoperative and postoperative data of patients included. The variables with a P <0.1 were included in the multivariate Logistic regression analysis of EBV infections after pediatric liver transplantation for patients with biliary atresia. Results A total of 30 cases (46.15%) of pediatric recipients showed EBV infection in 65 cases, of which 23 cases (76.67%) occurred within 3 months after operation. The univariate analysis showed that there were significant differences in the ratio of patients younger than 1 year preoperation, EBV serology D+/R-, acute rejection, the usage of mycophenolate mofetil and supratheraputic tacrolimus level between two groups (P<0.05) . The type of graft (P=0.060), input quantity of red blood cell intraoperation (P=0.063) and factors mentioned above were included in the multivariate Logistic regression analysis. It revealed that donor EBV serology positive but recipient negative, acute rejection and supratheraputic tacrolimus level were risk factors of EBV infection for pediatric liver transplantation recipients with biliary atresia. Conclusion Donor EBV serology positive but recipient negative, acute rejection, supratheraputic tacrolimus level are closely related to EBV infection in pediatric recipients with biliary atresia after liver transplantation. Appropriate antiviral drugs should be adopted to prevent EBV infection in high risk patients.

Objective To summarize the clinical characteristics and treatment of rotavirus infection after liver transplantation in children.Methods Thirty nine children undergoing liver transplantation in Beijing Friendship Hospital affiliated to Capital Medical University from October to December 201 4 were retrospectively analyzed.And 6 cases were infected with rotavirus after liver transplantation.Characteristics of clinical symptoms,complications,treatments and prognosis in these six children were retrospectively analyzed.Results Six cases were diagnosed with rotavirus infection at 8-1 97 d after liver transplantation with a median time of 22 d,3 cases of whom mainly manifested as high fever,diarrhea and vomiting and the remaining 3 presenting with diarrhea.The longer interval time between rotavirus infection and liver transplantation was,the slighter degree of rotavirus infection-related symptoms was.Among 6 cases,5 cases were complicated with EB virus,cytomegalovirus or respiratory syncytial virus,and 2 cases were complicated with abnormal liver or heart function.The main treatment was decreasing the dose of FK506.Gamma globulin was administered in partial affected children to enhance immunity.Effective therapy was delivered to regulate intestinal tract bacterial colony and relieve diarrhea.All children recovered after oral use of antibiotics and supporting therapy using fluid infusion.Two cases complicated with severe cardiac and liver function abnormality were healed after expectant treatment.Conclusions Rotavirus infection-related symptoms are relatively severe after liver transplantation in children,occasionally complicated with cardiac and liver function injury,which can gradually return to normal after efficacious therapy.
