Objective To investigate the expression of galectin-10 in CD4+CD25+CD127low/-regulatory T cells(Treg) and the correlation between expressions of galectin-10 and Foxp3.Methods CD4+CD25+CD127low/-Treg cells and CD4+CD25-CD127+ T cells were isolated from PBMC of healthy volunteers and lymph nodes of gastric cancer patients by flow cytometry.Following RNA micro-extraction RT-PCR analysis was used to detect mRNA expression of galectin-10 and Foxp3.Results The mRNA expression of galectin-10 and Foxp3 were dominant in Treg cells,whereas nearly no expression in CD4+CD25-CD127+ T cells.The results from PBMC of healthy volunteers and lymph nodes of gastric cancer patients were consistent between.Conclusion The expression of galectin-10 was obviously high in Treg cells,so it may become a novel marker for phenotypic characterization of Treg cells.

The experiment was designed to compare the changes of cytoskeleton (including tubulin and actin) and cell surface fibronectin (FN) between NIH 3T3 cell line and transformed NIH 3T3 cell line by genome DNA of human lung adenocarcinoma cell line AGZY. We stained and observed these cells using immunohistochemical methods with antibody against bovine brain tubulin, phalloidin and self-made affinity column purified antibody against porcine plasma FN.Our results showed that the bundles of actin and tubulin are damaged seriously, demonofrating an unclear cytoskeleton structure and diffused fluorescence over the cells when they were transformed. The amount of membrane FN on transformed cell surface decreases significantly which is only 1/9 of NIH 3T3. The FN distribution altered markedly from thin threadlike network to spots and speckles.These results suggested that cell transformation was a complex event including the changes of cytoskeleton system and cell surface glycoproteins. In addition, it might also indicate that cause and effect relationship existed between these changes and the alteration of cell phenotype and loss of growth control.

Objective To explore the moderating and mediating roles of psychological capital in the associations of effort?reward imbalance and overcommitment with job burnout among iron?steel workers. Methods Totally 1 700 male iron?steel workers from an iron and steel company were enrolled for the study. A set of questionnaires that included demographic and working factors,the Maslach Burnout Inventory?General Survey,the Ef?fort?reward Imbalance Scale and the Psychological Capital Questionnaire,as well as perceived work environment was distributed to the subjects. A to?tal of 1 254 effective respondents(73.76%)were collected. Hierarchical linear regression analysis was performed to explore moderating role,and as?ymptotic and resampling strategies were used to detect mediating role. Results There was no moderating role of psychological capital on the associa?tion between effort?reward imbalance and job burnout. Psychological capital had significant and positive moderating roles on the associations of over?commitment with emotional exhaustion and cynicism. Psychological capital showed significant mediating role in the associations of effort?reward im?balance with emotional exhaustion and cynicism,and the proportion of mediating role was 5.84%and 18.75%,respectively. Conclusion In work?ers with high level of psychological capital,emotional exhaustion and cynicism would be significantly increased with overcommitment,and there is a weak increasing trend of emotional exhaustion and cynicism in workers with low level of psychological capital. Effort?reward imbalance could lead to emotional exhaustion and cynicism through the reduction of psychological capital of iron?steel workers.
