Background and purpose: Sorafenib, a multiple targeted agent, can inhibit proliferation and induce apoptosis of diverse tumor cell in vitro. It has extensive biological activities, but the pancreatic cancer effect of monotherapy is poor. This may be related to nuclear factor-kappa B (NF-κB) pathway activation in cancer. Therefore, it is necessary to combine with Pyrrolidinedithiocarbamate (PDTC, a NF-κB activation inhibitor) to enhance curative effect. To investigate the influences of cell proliferation, cell cycle and expression of NF-κB via their acting on human pancreatic cancer PANC-1, and explore their possible mechanism. Methods:The experiment groups were divided into sorafenib group with different concentrations (1.5, 3.0, 6.0, 12.0 μmol/L), PDTC group with different concentrations (10.0, 25.0, 50.0, 100.0 μmol/L) and combination group with low concentration (3.0 μmol/L sorafenib+25.0 μmol/L PDTC). The proliferative activity of PANC-1 of each group was measured by MTT assay at different time points of 24

Objective To identify the correlation between doctors' job burnout and medical errors.Methods In stage 1,a cross-sectional retrospective survey on doctors' job burnout and medical errors was conducted for 300 doctors serving in the First Affiliated Hospital of Fujian Medical University,who were randomly sampled in June 2013.The survey covered basic demographic information,self-assessed job burnout and medical errors.In stage 2,231 doctors without medical errors in stage 1 were selected for a prospective study focusing on a follow-up on their medical errors within half a year.Results Medical errors were found to influence job burnout of doctors significantly.Multiple logistic regression analysis was made based on the three independent variables of A-emotional exhaustion,B-depersonalization,and C personal sense of accomplishment,and the dependent variables Y1 and Y2 indicating the occurrence or non-occurrence of common medical errors or serious medical errors,respectively.The calculation aims to identify if there is line relationship among the three independent variables.Conclusions This study suggests that all kinds of medical errors influence job burnout;scores of the three dimensions of job burnout may be predictors of occurrence of different medical errors.

Objective:To study the feasibility of transplantation of normal rat penile corpus cavernosum and major pelvic ganglion (MPG)into the renal subserous region of a Nu /Nu mouse based on allograft technology.Methods:Penile corpus cavernosum and MPG,harvested from Sprague-Dawley (SD)rats under sterile condition,were transplanted underneath the kidney capsule of Nu /Nu mice through the mi-crosurgery instruments and surgery microscope.The histopathologic changes and cellular proliferation in the transplanted penile corpus cavernosum and MPG were then analyzed at the end of 1week and 4 weeks after transplantation.Histological staining and immunohistochemical staining were used to evaluate the main outcome measures.Results:After 1 week,the tissue morphology of the transplanted corpus caverno-sum underneath the kidney capsule of Nu /Nu mice was consistent with normal penile corpus cavernosum, and blood could be observed in the penis cavernous sinus of the graft;after 4 weeks,the mophorlogy of the tranplanted corpus cavernosum near the kidney was consistent with normal penile corpus cavernosum, while fibrosis was noteworthy in the graft away from the kidney,but blood could still be seen in the penis cavernous sinus.After 1 week,the tissue morphology of the transplanted MPG was consistent with normal MPG,multiple islet-like cell clusters could be seen in the transplanted MPG in the renal subserous re-gion,and angiogenesis could be observed near the kidney;after 4 weeks,a network of blood vessels was clearly visible away from the kidney,and islet-like cell clusters were still clearly observed in the trans-planted MPG.In addition,ki67 positive cells were observed in the transplanted penile corpus cavernosum and MPG after 4 weeks of transplantation,which indicated that there was still cell proliferation activity in the grafts.Conclusion:The transplanted corpus cavernosum and MPG underneath the kidney capsule of Nu /Nu mice could survive at least 4 weeks.Moreover,the inner structure of the transplanted corpus ca-vernosum and MPG was close to the normal tissue.The underlining mechanism may be related to the lo-cal microenvironment underneath the kidney capsule of Nu /Nu mice and the neovascularization in the transplanted grafts.
