The aim of this study was to compare the percentage of T cells, natural killer (NK) cells and natural killer T (NKT) cells within decidual parietalis of normal pregnant controls (NP) and patients with intraheptic cholestasis of pregnancy (ICP), and to investigate the production of interleukin-4 (IL-4), interferon-γ (IFN-γ) in the culture supernatant of decidual parietalis mononuclear cells (DPMCs). Compared with controls, the decidua parietalis from ICP were characterized with significant increased percentages of CD3-CD56+ cells, CD3+CD56+ cells, CD56+CD16+ cells, CD56+CD16- cells, CD56+NKG2D+ cells, and the significant decreased percentages of CD3+ cells, CD3+CD4+ cells. There were no differences found for the percentage of CD3+CD8+ cells, CD56+NKG2A+ cells between control and study group. In addition, the enhanced concentration of IFN-γ was presented in culture supernatant of DPMCs from ICP. It was suggested that the increased NK cells, NKT cells and the decreased T cells in the decidual parietalis and over-secretion of IFN-γ could be correlated with the pathophysiology of ICP patients.展开更多

In this study,to investigate whether NK cells and NKT cells,instead of T cells,are the dominant populations of peripheral blood in early pregnancy,flow cytometry was used to detect the percentage and intracellular cytokine expressions of T cells,NK cells,NKT cells in peripheral blood of non-pregnant women and early pregnant women. In our result,the percentages of NK cells and NKT cells were significantly increased in pregnancy compared to non-pregnancy. However,the percentage of T cells was not changed. We did not detect the Th2-dominance of total lymphocytes or T cells in peripheral blood of early pregnant women and there were also no significant changes of type 1 and type 2 cytokines in T cells,but IFN-γ production in both NK and NKT cells was decreased in early pregnancy. These results suggest that the innate immune system including NK cells and NKT cells should play a pivotal role in pregnancy progression. Type 1/type 2 shift mechanisms in innate immune system during the human early pregnancy should be paid more attention.展开更多

However, CF is vulnerable to shilling attackers who inject fake user profiles into the system. In this paper, we first present the shilling attack problem on CF-based QoS recommender systems for Web services. Then, a robust CF recommendation approach is proposed from a user similarity perspective to enhance the resistance of the recommender systems to the shilling attack. In the approach, the generally used similarity measures are analyzed, and the DegSim (the degree of similarities with top k neighbors) with those measures is selected for grouping and weighting the users. Then, the weights are used to calculate the service similarities/differences and predictions. We analyzed and evaluated our algorithms using WS-DREAM and Movielens datasets. The experimental results demonstrate that shilling attacks influence the prediction of QoS values, and our proposed features and algorithms achieve a higher degree of robustness against shilling attacks than the typical CF algorithms.展开更多
