Objective To discuss the advance and experience of postoperative management in multivisceral transplantation(MVT).Methods Five patients with abdominal multiple organs malig- nances were subjected to multivisceral transplantation.The excised specimens included the liver,pan- creas,duodenum,stomach,spleen,mesentery and all of the involved lymph nodes.The transplanted organs were liver,pancreas,duodenum and parts of intestine.Patients were monitored and sustained stably in breath,hemodynamics and homoeostasis.The coagulation was also monitored and kept in balance.The intensive immunosuppressive protocol,including steroid,tacrolimus,mycophenolate mofetil and Zenapax,was used to prevent the acute rejection.The endocrine and exocrine of pancreas were tested,color Doppler examination was done every day,and Somatostatin was used to prevent pancreatitis.Drugs to bacteria,fungus and virus infection were prophylactically used.Results All patients waked up with 4-6 h after operation and began recovering with 3-7 days.Dynamic examina- tions revealed that the functions of grafted liver,pancreas and duodenum were satisfactory.No com- plications of acute rejection,pancreatitis,bleeding and thrombosis occurred.Conclusion Many ques- tions in postoperative management related to multivisceral transplantation are devoted to study.Nice experience of management to organ transplantation,detailed monitoring and prophylactically medica- tions are safeguards to steady recovering and further prognosis.

AIM: To investigate the angiogenesis effect and protective mechanism of cordycepin on rhesus macaque choroid- retinal endothelial ( RF/ 6A) cell line cultured in high glucose condition.
METHODS: Cultured RF/ 6A cells were divided into normal control group, high glucose group and high glucose (HG) + different concentration cordycepin groups (HG+ 10μ g/ mL group, HG+ 50μ g/ mL group, HG+ 100μ g/mL group). The cell proliferation was assessed using cholecystokinin octapeptide dye after treated for 48h. The cell migration was investigated by a Transwell assay. The tube formation was measured on Matrigel. Furthermore, the impact of cordycepin on high glucose - induced activation of VEGF and VEGF receptor 2 (VEGFR-2) was tested by Western blot analysis.
RESULTS: Compared with normal control group, cell viability markedly increased in high glucose group ( P <0. 05). Cordycepin inhibited RF/ 6A cell proliferation in a dose- dependent fashion: 10. 2 ± 0. 9%, 23. 4 ± 1. 5% and 31. 1±1. 2% inhibition as the concentrations of cordycepin were 10, 50 and 100μ g/ mL, respectively. The difference had statistically significant (P<0. 05) compared with high glucose group. The number of cell migration were 55. 6±2. 70, 87. 4 ± 2. 40, 65. 4 ± 2. 7, 57. 8 ± 2. 38, 62. 4 ± 2. 77 in normal control group, high glucose group and HG+10μ g/mL group, HG + 50μ g/ mL group, HG + 100μ g/ mL group respectively. Migration of RF/ 6A conspicuously increased in high glucose group ( P < 0. 05) compared with normal control group; while showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference compared with high glucose group (P<0. 05). The number of tube formation were 18. 7±2. 08, 25. 7 ± 1. 52, 19. 9 ± 1. 57, 16. 3 ± 2. 51, 5. 67 ± 1. 72 in the abovementioned group. Similarly showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference with high glucose group (P< 0. 05). In addition, the number of tube formation of RF/ 6A in high glucose group significant increased compared with normal control group ( P < 0. 05 ). The expression of VEGF and VEGFR-2 dramaticlly increased in high glucose group vs normal control group, oppositely gradually decreased with the increase of cordycepin concentrations, and had a statistically significant difference vs high glucose group (P<0. 05).
CONCLUSION: Cordycepin can suppress the proliferation, migration and tubu formation of RF/ 6A in high glucose condition, might via inhibiting expression of VEGF and VEGFR-2.

Objectives To investigate the prevalance of quinolone resistance in Laribacter hongkongensis and to evaluate the influence of agar dilution and disc diffusion methods on susceptibility testing for the bacterium. Methods Susceptibility to quinolones of L.hongkongensis was tested by agar dilution and disc diffusion methods. The results for both methods were compared. Results L.hongkongensis isolates exhibited different susceptibility rate for quinolones (levofloxacin>ciprofloxacin>norfloxacin>nalidixic acid). All of the fish isolates were susceptible to levofloxacin and more than 90%were susceptible to ciprofloxacin and Norfloxacin. However,by agar dilution, only 62.50%, 37.50%,48.21%, 19.64%of the frogs isolates were susceptible to levofloxacin, norfloxacin, ciprofloxacin, nalidixic acid, respectively. For fish isolates, comparision of susceptibilities between agar dilution and disc diffusion showed a high (> 95%) percentage agreement for levofloxacin and ciprofloxacin and the highest crepancies were observed with norfloxacin (100%) .But it showed a high discrepancy when comparing the two methods for frogs isolates. Conclusions The resistance rate of L. hongkongens to quinolones was high , especially for frog isolates. The results suggested the use of agar dilution on susceptibility testing for quinolones in L. hongkongensis.
