Objective To study the protective effect of resveratrol on endothelial cells injury induced by oxidized low-density lipoprotein (oxLDL) and its protective mechanism. Methods The injured model was established by endothelial cell treated with oxLDL. In the experiment, endothelial cell were cultured in vitro and divided into seven groups which were: control group; solvent (DMSO) group, oxLDL group, quercetin plus oxLDL group, Reseveratrol-L (0.5 mol/L), M(5 mol/L), H(50 mol/L) plus oxLDL group respectively. Endothelial cells were incubated with 200?g/ml oxLDL for 18 hours in the absence or presence of various concentrations of resveratrol and quercetin. The apoptotic index was detected by flow cytometric. Meanwhile, the content of Malondialdehyde (MDA), and the activity of SOD, GSHPX in the culture medium and homogenate of endothelial cells were measured. Results Incubation of endothelial cells with oxLDL for 18 h elicited a significant increase in the percent of apoptotic endothelial cells, in control group, the percent of apoptotic cells is 7.6?0.6, however in oxLDL group, it increased to 41.4?2.3, furthermore, oxLDL induced the increase of the contents of MDA, and accompanied by the decrease in the activity of SOD, GSHPX in the endothelial cells, the difference of was significant as compared with control group. Pretreatment of resveratrol with 0.5~50 mol/L decreased these oxLDL-induced changes, in Reseveratrol with 50 mol/L group, the percent of apoptotic cells decreased to 13.0?1.5, the difference of was significant as compared with oxLDL group (P

Objective To investigate the histogenesis,clinicopathological features and biological behavior of goblet cell carcinoid (GCC) of the appendix. Methods 3 cases of GCC of the appendix were studied by light microscopy and immunohistochemistry. Results 3 cases all occured in men. Microscopically: the tumor was composed of goblet cells containing mucin-filled with basal round to crescentic nuclei without atypia.These tumor cells were arranged in single forms,nests or acinus with no central lumen. 1 case was composed of simple goblet cells and typical carcinoid cells were seen in other 2 cases arranged in trabeculae and tubule.There was transition between goblet cells with tubelar and crypt epithelium.Immunohistochemical staining revealed that goblet cells were positively reacted with CgA, Syn, CEA, CK and p53 in 1 case. Conclusions Goblet cell carcinoid of the appendix arise from a pluripotent cell with divergent neuroendocrine and mucinous differentiation .It is a subtype of carcinoids of the appendix.The diagnosis mainly bases on its morphologic changes and immunohistochemical findings. The unpredictable behavior of this tumor is probably related to its component and the degree of infiltration.

Objective To investigate the stabilization of betaine on the enzyme activity of ALT in human serum at different temperatures, and to evaluate the matrix effects of human serum with betaine among different analytical systems. Methods The enzyme activity of ALT in human serums with l mol/L betaine stored at 37 ℃, 25 ℃, 4 ℃ and - 20 ℃ respectively were measured. The matrix effect experiment was carried out according to the procedures specified in Clinical and Laboratory Standards Institute (CLSI)document EP14-A. Four analytical systems were the candidates for evaluation, and Roche Diagnostics (Roche)-Hitachi analytical system served as the reference system. The enzyme activity of ALT of 40 patient specimens and 3-level specimens ( high, medium and low) with 1 mol/L betaine were measured using the evaluated methods and the reference method respectively. The linear regression analysis was performed to compare the mean y value of 3-level specimens with the statistically defined limits ( the two-tailed 95% prediction interval) derived from 40 patient specimen data. Results The enzyme activity of ALT could be stabilized with betaine in serum, which remained to be 99% for 48 h at 37 ℃, 98% for4 d at 25 ℃, 97%for 4 weeks at 4 ℃, and 99% for 4 months at - 20 ℃. The enzyme activity of control serum decreased to 42%, 86%, 71%, 79% respectively. The mean y values of three specimens with the betaine were within the 95% prediction interval of the estimated mean y values, which suggested no obvious matrix effects in serum. Conclusion Betaine can be used in the development of enzyme ALT calibrator as its stabilizer.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.
