BACKGROUND:Perioperative treatment of emergency liver transplantation for acute hepatic failure is extremely different from common liver transplantation, due to complex conditions, high risk, several complications, and high mortality. OBJECTIVE:To summarize the experience of emergency liver transplantation for acute hepatic failure during the perioperative period, and to increase the success rate in treatment of acute hepatic failure. METHODS:A retrospective analysis was undertaken on the clinical data of 38 cases undergone emergency liver transplantation for acute hepatic failure. There were 21 male and 17 female, who aged 15-69 years. Among them, 23 cases had hepatitis B virus (including 2 cases with hepatitis B and C virus), 7 cases had Wilsons disease, 3 cases had mushroom poisoning, 2 cases had unknown liver damage, 1 case had Tripterygium wilfordi poisoning, 1 case had decompensation after partial liver resection due to trauma, and 1 case had liver transplantation from corpse. RESULTS AND CONCLUSION:The survival time of the involve patients was 13-1 740 days, and the median survival time was 634 days. Perioperative survival rate was 76%, 1-year survival rate was 63%, and 2-year survival rate was 58%. During the perioperation nine cases died of brain edema and intracranial hypertension, renal failure, severe pulmonary infection, multiple organ failure, coagulation disorders (intracranial hemorrhage, upper digestive tract hemorrhage), acute respiratory distress syndrome and primary graft non-function. At present, emergency liver transplantation is stil the most effective way for acute liver failure. Hemorrhage, infection and rejection are the leading causes of the death. Each perioperative treatment is of great significance for the success of liver transplantation and long-term survival.

Objective To explore the clinical effect of radio-frequency ablation in the treatment of advanced pancreatic cancer.Methods Retrospectively analyzed the clinical data of 28 cases of radio-frequency ablation in the treatment of advanced pancreatic cance between January 2008 and December 2012 in 304 hospital.And choosed made 140 cases patients who only underwent the conservative treatment as the control group at the same period.Then compared the data of two groups patients.Results The mean tumor diameter was (4.8 ± 1.6) cm.The average radio-frequency time was (17.7 ± 4.3) minutes.There was no patient occurred of pancreatic fistula or postoperative bleeding,and no patient dead.Peri-operation pain relief rate was 88.9％.Twenty-three patients were followed up,and the follow up rate was 82.1％.The patients' survival rate who underwent radio-frequency ablation of 1 month,6 months and 1 year were 95.7％,65.2％ and 38.2％.The average survival time was (14.6 ± 2.2) months.And the data was significantly higher than that of the control group patients (97.4％,45.3％,19.1％,P =0.0306).Conclusions The radio-frequency ablation was one of an effective treatment method for the advanced pancreatic cancer patients.It can prolong the survival time of pancreatic cancer patients and alleviate the patient's pain.

Objective To monitor the protective qualities of personal protective appliances and to ensure the health and safety of radiological working personnel.Methods The lead-equivalent thickness of personal protective appliances and materials was measured by means of standard lead slices.The lead equivalent thickness represents in terms of mm Pb.Results 77 pieces of products and samples were measured altogether.The results indicate that the specific lead equivalents of lead-rubber plates were between 0.20-0.39 mm Pb/mm for 37 pieces of lead-rubber plates and the values of 6 pieces of samples were less than 0.25 mm Pb/mm,which did not accord with the requirement of the relational standard.27 pieces of personal protection appliances were measured altogether.They were 12 pieces of protective clothes,4 pieces of protective headgears,5 pieces of protective neckpieces,4 pieces of protective gloves and 2 pieces of protective masks.13 pairs of lead-glass spectacles among them were measured altogether.The measured results for personal protective appliances and lead-glass spectacles showed that actually measured lead-equivalent were higher than the nominal lead-equivalent.Conclusions The protective qualities are reliable for personal protection materials and appliances to be made in home and imported abroad.But the protective qualities of interventional protection gloves should be improved and made them better.

Objective To assess the clinical value of 18 F-FDG PET/CT for the patients with ascites of unknown causes.Methods A total of 106 patients with ascites undergoing 18 F-FDG PET/CT examination was retrospectively studied and 18F-FDG PET/CT imaging was interpreted by two ways.(1)PET/CT(localization):Diagnostic results of PET/CT depended on the degree of 18 F-FDG uptake in peritoneum with CT was trecoted as anatomical localization,and high 18F-FDG uptake in peritoneum was regarded as malignancy.(2)PET/CT(mor-phology):Morphological changes of peritoneum on CT imaging and the degree of 18 F-FDG uptake on PET ima-ging were simultaneously considered when interpreting the diagnostic results of PET/CT.Results In the differen-tial diagnosis of ascites of unknown cause,the sensitivity,specificity and accuracy of PET/CT( localization) were 90.2%,71.1%and 82.1%,respectively.These values of PET/CT(morphology)were 95.1%,93.3% and 94. 3%,and 85.2%of malignant ascites were found primary lesion.The specificity and accuracy of PET/CT( mor-phology)were higher than those of PET/CT(localization)(P=0.002,P<0.001).Statistical difference was not found in both sensitivities.Conclusion PET/CT( morphology) had higher clinical value than PET/CT( localiza-tion) in the differential diagnosis of ascites with unknown cause,and had important significance in detecting pri-mary cause of malignant ascites.

Objective To investigate the usefulness of HC visual laryngoscope designed for unskilled junior emergency resident doctors in respect of increasing the efficiency and success rate of emergency tracheal intubation.Methods A total of 80 patients needed the emergency tracheal intubation were at first divided into two groups randomly (random number).Patients in group A were operated by junior emergency resident doctors and patients in group B were operated by well experienced attending doctors.Then,the two groups of patients above were divided into two groups randomly (random number).Patients in group N were operated with conventional laryngoscope and patients in group HC were managed with HC visual laryngoscope.Then comparisons of the success rate of glottis exposure,the one-time success rate of tracheal intubation,the success rate of tracheal intubation,the complications,the number of attempt in successful intubation cases and the operative time consumed for successful intubation cases among the groups were done.Results (1)The success rate of glottis exposure,the one-time success rate and the success rate of tracheal intubation in group A-HC were 90%,70% and 90%,respectively which were significantly higher than those (50%,20% and 45%)in group A-N (P <0.05).The rate of complication,the number of attempt and operative time consumed for intubation cases in group A-HC were respectively 15%,(1.28 ± 0.43)and (31.44 ±5.06 ) s,which were significantly less than those [45%,(1.89 ±0.79 )and (45.89 ±4.99) s in group A-N (P <0.05 ).(2)The success rate of glottis exposure,the one-time success rate and the success rate of tracheal intubation in group B-N were 80%,65% and 80%, respectively which were significantly higher than those (50%,20% and 45%)in group A-N (P <0.05). The rate of complication,the number of attempt and operative time consumed for successful intubation cases in group B-N were 15%,(1.25 ±0.41)and (39.31 ±4.23)s,respectively which were significantly less than those [45%,(1.89 ±0.79)and (45.89 ±4.99)s]in group A-N (P <0.05).(3)There were no significant statistical differences in above results between group A-HC and group B-HC (P >0.05 ). Conclusions HC visual laryngoscope used by unskilled junior emergency resident doctors for emergency tracheal intubation,could increase success rate of glottis exposure,decrease the number of attempt of intubation,decrease rate of complication,shorten operative time required for intubation thus improving efficiency and success rate of emergency tracheal intubation,and maybe narrow the skill gap between unskilled junior resident doctors and well experienced attending doctors in respect of emergency tracheal intubation.
