Objective To explore the operative technique of liver retransplantation.Methods The clinical data of 24 patients who underwent liver retransplantation in the recent 4 years in our center were reviewed.In all of the patients a modified piggy-back liver transplantation was adopted.Extracorporeal venous bypass was used in 6 cases,and no bypass was used in 18 cases.We anastomosed the suprahepatic inferior vena cava to the annexed vena cava in a modified piggy-back figuration.The portal vein was reconstructed by end-to-end anastomosis.In 17 cases the hepaticy artery was anastomosed end-to-end,and in the other 7 cases was(anastomosed) to abdominal aorta by interposition graft.In 6 cases the biliary tract was reconstructed by(end-to-end) anastomosis,and in the others by choledochojejunostomy.All of the patients were routinely followed up after operation.Results Postoperative mortality of liver retransplantation was 41.6%(10/24).The cause of death was sepsis in 7 patients,intraoperative bleeding in 2,and cerebral hemorrhage in 1.The other patients(14/24,58.4%) successfully recovered after liver retransplantation.The complication rate in this group was 21.4%%(3/14),including biliary tract complications in 2 patients,and wound dehiscence in 1.Conclusions There was no significant difference in operative time and blood loss between liver(retransplantation) and primary transplantation.The key for success is to adopt individuation in selection of(methods) for liver retransplantation.The difficulty of liver retransplantation is exposure and mobilization of(inferior) vena cava. The probability of interposition graft from hepatic artery to abdominal aorta and(choledochojejunostomy) is higer than that of primary liver transplantation.

ObjectiveTo explore the clinical characteristics of pathological fracture in extremities caused by bone tumors or tumor-like lesions. MethodsFrom August 2002 to December 2010, 139 patients with pathological fractures were entered in the study, including 79 males and 60 females with an average age of 31.1 years. Fractures included tumor-like lesion in 55 cases, benign tumor in 13, giant cell tumor (GCT)in 7, primary malignant tumors in 28, and metastatic tumors in 36. Forces induced to fractures were classified into four grades: spontaneous fracture, functional activity, minor injury, severe injury. Age, fracture location, histological results, fractures forces, prodromes, and misdiagnosis were all observed. Chi-square test were use to compare forces and prodromes within different tumors. ResultsThe highest morbidity rate is 32.4％(45/139) which lies in 11-20 years old. The cites of fractures including femurs in 71 cases, humerus in 36, tibia in 15, fingers in 7, radiuses in 4, fibula in 3, ulnas in 2, and metatarsus in 1. Fracture forces include spontaneous fractures in 29 cases, functional activity in 42, minor injuries in 65, and traumatic injuries in 3. Sixty-seven patients(48.2％) had local prodromes. The prodromes of both malignant tumors and metastatic tumors were more than benign tumors. Twenty cases experienced misdiagnosis with average delay time of 12 weeks. ConclusionMinor injury forces and local prodromes are clinical key features of pathological fractures. Both of them are key points of avoiding misdiagnosis.

: Knowledge, attitudes and practices (KAP) impact on cardiac disease outcomes, with noted cultural and gender differences. In this Asian cohort, we aimed to analyse the KAP of patients towards cardiac diseases and pertinent factors that influence such behaviour, focusing on gender differences.: A cross-sectional survey was performed among consecutive outpatients from a cardiac clinic over 2 months in 2014.: Of 1406 patients approached, 1000 (71.1%) responded (mean age 57.0 ± 12.7 years, 713 [71.3%] males). There was significant correlation between knowledge and attitude scores (r = 0.224,<0.001), and knowledge and practice scores (r = 0.114,<0.001). There was no correlation between attitude and practice scores. Multivariate predictors of higher knowledge scores included female sex, higher education, higher attitude and practice scores and prior coronary artery disease. Multivariate predictors of higher attitude scores included higher education, higher knowledge scores and non-Indian ethnicity. Multivariate predictors of higher practice scores included male sex, Indian ethnicity, older age, higher knowledge score and hypertension. Males had lower knowledge scores (85.8 ± 8.0% vs 88.0 ± 8.2%,<0.001), lower attitude scores (91.4 ± 9.4% vs 93.2 ± 8.3%,= 0.005) and higher practice scores (58.4 ± 18.7% vs 55.1 ± 19.3%,= 0.013) than females.: In our Asian cohort, knowledge of cardiovascular health plays a significant role in influencing attitudes and practices. There exists significant gender differences in KAP. Adopting gender-specific strategies for future public health campaigns could address the above gender differences.

PURPOSE: To correlate the pathologic and MR findings of distal femoral cortical irregularity(DFCI) in adult. MATERIALS AND METHODS: We retrospectively reviewed knee MR images of 120 adult patients(25-62 years old) without infection, tumor, or fracture. Five femoral specimens of adult cadaver were used to correlate pathologic and MR findings. A double cortical line' on MR images was interpreted as DFCI, and MR findings were analyzed to determine the thickness, internal signal intensity, location of the DFCI, shape of the external cortex, and clarity of the inner cortex. The outer cortex was classified as either convex or flat, and the inner cortex was classified according to its thickness and continuity as one of three types. RESULTS: One hundred and sixteen patients(97%) had DFCI, which in all cases was observed at the attachment site of the medial head of the gastrocnemius muscle. Mean thickness was 3.7mm and DFCI was thicker in men than in women(p<0.05). The outer cortex was convex in 75 cases(65 %) and flat in 41(35 %). The inner cortex was thick and continuous in 47cases(41 %, mean age 31), thin and continuous in 54(47 %, mean age 38), and thin and discontinuous in 19(16 %, mean age 47). Clarity tended to diminish with age. The internal area of DFCI showed signal intensity equal to that of adjacent bone marrow and was pathologically proven to be normal marrow tissue. CONCLUSION: DFCI was observed in most adults and was considered to be a normal variation. Its MR and pathologic findings were different to those observed during periods of growth.

There were 4 Acinetobacter lwoffii obtained from soil samples. The antimicrobial susceptibility of the strains to 16 antimicrobial agents was investigated using K-B method. Three isolates showed the multi-drug resistance. The presence of resistance genes and integrons was determined using PCR. The aadA1, aac(3')-IIc, aph(3')-VII, aac(6')-Ib, sul2, cat2, floR, and tet(K) genes were detected, respectively. Three class 1 integrons were obtained. The arr-3-aacA4 and blaPSE-1 gene cassette, which cause resistance to aminoglycoside and beta-lactamase antibiotics. Our results reported the detection of multi-drug resistant and carried resistant genes Acinetobacter lwoffii from soil. The findings suggested that we should pay close attention to the prevalence of multi-drug resistant bacterial species of environment.
