X-ray diffraction （XRD） analyses showed that BTO films were c-axis oriented and epitaxially grown on platinum coated MgO substrates, and （110） epitaxial Fe films were subsequently grown on （001） BTO films. Fe/BTO bi-layer films showed good ferroelectric and ferromagnetic properties at room temperature and the multiferroic coupling was observed, which should be attributed to the hybridization of Fe and Ti occurring at the ferromagnetic-ferroelectric interface.展开更多

Methods: A total of 95 cases of tumor admitted to our hospital from February 2015 to February 2017 were selected according to the order of admission, divided into the study group (n=47) and the control group (n=48). In the control group, the traditional blind catheterization was carried out, and the research group improved the puncture method. The rate of puncture success (onetime puncture success rate, total success rate), puncture time and complication rate were compared between the two groups. Results: The total success rate (77.1%) of the study group (97.9%) was significantly higher than control group, The puncture time of the study group was significantly shorter than control group. Incidence of complications in the study group (4.3%) was significantly lower than that in the control group (22.9%). Conclusions: The improved puncture method can significantly reduce the incidence of complications after PICC catheterization, shorten the puncture time and improve the success rate of puncture, which is worthy of reference and promotion.展开更多
