XRD and XPS characterizations of the catalysts show the structure defects, which may be produced by the partial exchange of anions and cations,enhance the electron donating ability and increase the surface absorbed oxygen concentration thus should be favorable to improve the catalytic activity. However, the higher concentration of surface adsorbed oxygen is unfavorable for the ethene selectivity.展开更多

Methods: Eighty postoperative patients of breast cancer were selected and divided into two groups, the treated group (40 cases) was given intravenous Shenmai injection for 7 days and compared with the control group (40 cases) in wound healing time, postoperative drainage volume, complication and blood picture, and the NK cell, T lymphocyte subsets (CD 3, CD 4, CD 8), were compared before and after treatment. Results: The wound healing time and postoperational complication in the treated group were less than those in the control group significantly. There was no difference between the two groups in WBC and platelet count, but the recovery of hemoglobin in the treated group was quicker than that in the control group significantly (P<0 05), as comparing with the control group, the NK cell, CD 4, CD 4/CD 8 ratio in the treated group were elevated faster than those in the control group significantly (P<0 05). Conclusion: Shenmai injection was beneficial to the recovery of postoperative patients of breast cancer, to reducing the occurrence of complication and was favorable to conduct postoperative chemotherapy smoothly.展开更多
