Excessive electrolyte decomposition seriously determines the performance of high-voltage Mg batteries. In Nazar's work, the strategy using a zeolite polymer membrane as a protective interface was proposed to restrain the electrolyte decomposition. This strategy could boost Mg plating/stripping performance up to 6000 h in zeolite/Mg|zeolite/Mg symmetric cells and 91%capacity retention in zeolite/Mg||Mo_(3)S_(4)battery after 200 *** storage devices have been intensively explored because of their important roles in our daily lives [1D3].

T helper 17 （Th17） cells have both regulatory and protective roles in physiological conditions. The Th17 subset and the cytokine interleukin-17A （IL-17A） have been implicated in the pathogenesis of certain autoimmune diseases, several types of cancer and allograft rejection. However, the role of Th17 cells at the maternal/fetal interface remains unknown. Here, we demonstrate that Th17 cells are present in decidua and are increased in the peripheral blood of 10 clinically normal pregnancies based on intracellular cytokine analysis. Our results suggest a potential role of Th17 cells in sustaining pregnancy in humans. Furthermore, we demonstrate that decidual stromal cells （DSCs） but not trophoblast cells recruit peripheral Th17 cells into the decidua by secreting CCL2. The recruited Th17 cells promote proliferation and invasion and inhibit the apoptosis of human trophoblast cells by secreting IL-17 during the first trimester of pregnancy. These findings indicate a novel role for Th17 cells in controlling the maternal-fetal relationship and placenta development.

Background Overexpression of Bcl-2 protein in cancer cells can inhibit programmed cell death and engender chemoresistance. Bcl-2 antisense oligonucleotide （G3139） has shown its antitumor effects enhanced in preclinical models when combined with taxol-based chemotherapy. This study aimed to investigate the efficacy of G3139 combined with epirubicin in the androgen-independent prostate cancer. Methods PC3 prostate cancer cell line was cultured and treated with epirubicin and Bcl-2 antisense oligonucleotide alone or in combination. The effects of therapeutic agents on cells were determined by the MTT assay. Expression of Bcl-2 mRNA and protein was documented by RT-PCR and Western blotting. Apoptosis induction was confirmed by flow cytometric analysis. Results Bcl-2 antisense oligonucleotide alone produced no cytotoxic effects and the combination of Bcl-2 antisense oligonucleotide with epirubicin sensitized PC-3 cells to the killing effects of chemotherapy. A marked down-regulation of Bcl-2 mRNA and protein was observed after antisense and epirubicin cotreatment. A statistically significantly higher fraction of apoptotic cells was detected by flow-cytometric analysis after epirubicin treatment with prior antisense Bcl-2 transfenction, as compared with mono antisense Bcl-2 or epirubicin treatment. Conclusion These data suggested that inhibition of Bcl-2 expression combined with epirubicin may be an attractive therapeutic strateqy in hormone-refractory prostate cancer.
