Objective To investigate the postoperative complications of ex vivo liver resection combined with autologous liver transplantation in the treatment of end-stage hepatic alveolar echinococcosis at high altitude and related prevention and treatment strategies. Methods Surgical data and follow-up data were collected from 11 patients with end-stage hepatic alveolar echinococcosis who underwent autologous liver transplantation in Qinghai People's Hospital from January 2013 to March 2019, and intraoperative and postoperative conditions were analyzed. Results All 11 patients underwent autologous liver transplantation successfully, without intraoperative death, among whom 2(18.18%) underwent hemi-extracorporeal hepatectomy and 9 (81.82%) underwent total extracorporeal hepatectomy. For the reconstruction of the retrohepatic inferior vena cava, 2 patients (18.18%) underwent reconstruction with the autologous great saphenous vein, 4 patients (36.36%) underwent reconstruction with artificial vessels, and the autologous retrohepatic inferior vena cava was preserved in 5 patients (45.45%). For biliary reconstruction, 8 patients (72.73%) underwent choledochoenterostomy and 3 (27.27%) underwent choledochocholedochostomy. The main postoperative complications of the 11 patients included bleeding in 2 patients (18.18%), bile leakage and abdominal infection in 4 patients (36.36%), bilioenteric anastomotic stenosis in 1 patient (9.09%), thrombus in 2 patients (18.18%), pulmonary infection and pleural effusion in 2 patients (18.18%), and echinococcosis recurrence in 1 patient (9.09%). Of all 11 patients, 2 (18.18%) died during the perioperative period, and the other 9 patients (81.82%) were improved and discharged. Conclusion Bleeding, biliary complications, and infection are the main causes of death in patients undergoing autologous liver transplantation at high altitude. An accurate understanding of surgical indication, careful multidisciplinary evaluation before surgery, superb operation during surgery, standardized surgical procedures, and fine perioperative management are the key to reducing perioperative mortality, avoiding and reducing postoperative complications, and achieving good long-term survival in patients undergoing autologous liver transplantation.

Surgery management is key to surgical quality control. The authors presented the IT system design for surgery anesthesia of the children′s hospital of Fudan University, featuring all-process information support by means of IT development and process reengineering. Such a process comprises perioperative patient handover, medication, surgical safety check, and intraoperative care. This surgery anesthesia system development has interconnected hospital information systems within and beyond operation rooms in terms of informationization. It proves that the system can effectively enhance safety and convenience of surgery related works and supervision, reducing error exposure of surgical operations and ensuring patient safety.

Objective To analyze common postoperative complications after autologous liver transplantation in patients diagnosed with hepatic alveolar echinococcosis (HAE)from plateau area. Methods Clinical data of 6 patients with advanced HAE undergoing ex-situ or partially ex-situ hepatectomy combined with autologous liver transplantation were retrospectively analyzed. Clinical characteristics of postoperative complications were analyzed. Results Postoperative complications mainly included biliary tract complications (n=4),intra-abdominal hemorrhage (n=1 ),infection (n=3). Two cases presented with bile leakage complicated with intra-abdominal infection and died from infectious shock and multiple organ dysfunction syndrome. One patient had intra-abdominal hemorrhage and died from hemorrhagic shock and disseminated inravascular coagulation. Biliary tract complication and intra-abdominal hemorrhage were primary causes of mortality. Conclusions Biliary tract complication,intra-abdominal hemorrhage and infection are the main prognostic factors for HAE patients undergoing autologous liver transplantation.

Objective To explore the expression of matrix metalloproteinase-11 (MMP-11) gene in gastric cancer and its correlation with transcription factor Sp1.Methods The expressions of the MMP-11 and Sp1 in level of RNA and protein in 11 specimens from the gastric cancer patients s were detected by RT-PCR,differential PCR and Western-blot,respectively.Results Electrophoresis illustration showed MMP-11 mRNA expression had significant differences in eight pairs of gastric cancer tissues and normal tissues,including 7 pairs of over expressed in gastric cancer tissues and low or no expression in normal tissues,and 1 pair of low expression in cancer tissues but high in normal tissues.The relative molecular weight of Sp1 protein was mainly 95×103 in cancer tissue and 106×103 in normal tissues.Activated MMP-11 protein mainly was over expressed in gastric cancer tissues,and low or no expression in normal tissues,but degradable MMP-1 1 protein was not observed.The enzyme prototype of and activated type of MMP-11 protein were also associated with Sp1 protein.Conclusions The MMP-11 mRNA expression in gastric tissue is higher than that in the adjacent tissues.Sp1 protein and MMP-11 protein are expressed in gastric cancer,but are low or no expression in normal tissue.There is relationship between Spl and MMP-11.

Objective To investigate the extent of pancreatic and liver function damage of acute necrotizing pancreatitis (ANP) rats under altitude hypoxia environment,and to provide a reference for better diagnosis and treatment of severe acute pancreatitis (SAP) in the plateau region.Methods Ninety-six specific pathogen free (SPF) Wistar male rats were involved in 1 500 meters,3 300 meters and 4 300 meters altitude.The model of ANP was established by using pancreatic capsule injection of sodium taurocholate (NaTc).In the sham operation group,the rats' belly was opened and closed after only flipping its pancreas several times.Rats in sham group were sacrificed at 6 h,and ANP group were sacrificed at 6,12,24 h after modeling.Serum amylase activity was measured,and pancreas and liver tissue were harvested for pathological examination and score.Results Serum amylase activity in sham operation group rats was not remarkably changed,and pathological changes of pancreas and liver were not obvious.At same altitude,serum amylase activity,pancreas and liver pathology score of ANP rats at each time point were significantly higher than those in the sham operation group;and serum amylase activity,pancreas and liver pathology scores of ANP 12,24 h group rats were significantly higher than those of ANP 6h group;and the difference was statistically significant (P < 0.05).At 3 300 meters,4 300 meters altitude,the pancreas and liver pathology scores of ANP rats at each time point were significantly higher than those at 1 500 meters altitude,and the differences were statistically significant (P < 0.05),but the difference in serum amylase activity was not statistically significant.Conclusions With the increase of altitude,pancreatic and liver pathological damage of ANP rats shows continuing aggravation.

Objective To study the effect of bile reinfusion on immunologic function of erythrocyte in patients with obstructive jaundice after external drainage of biliary tract.Methods Patients with obstructive jaundice who had received biliary tract external drainage were randomly divided into bile reinfusion group ( n =24) and simple external drainage group ( n =27). Patients without jaundice,who received cholecystectomy in the same period with the above ones,were selected randomly as control group( n =25). In external drainage groups patients’ bile was collected daily, and was filtered through gauze, and then, pumped back into the patients’ duodenum or jejunum after being heated to 38 ℃-40 ℃. The bile reinfusion could be started after the intestinal function recovered postoperatively. The changes of C 3bRRT, ICRT, RFER and RFIR were observed before and after operation. The data were analysed through SPSS8.0.Results Preoperative C 3bRRT and RFER levels in patients with obstructive jaundice were lower than those without jaundice significantly, and Preoperative ICRT and RFIR levels in patients with obstructive jaundice were higher than those without jaundice significantly. C 3bRRT levels in bile reifusion group was higher obviously than those in simple drainage group ( P
