This form has multiple connotations,. Given recent changes in society, some think that, xiaojie (小姐） will become a widely-used form of address, while others think that young females will come to consider the title repulsive. None can have the final say, this is because the synchronic language differences are not only the result of the synchronic change but also possibly its sign. Since synchronic differences could not only be a result of diachronic change but also could herald further change, it is not clear what direction xiaojie (小姐） will take. In the language conflicts, When two language varieties conflict, the more common variety usually influences the less common. A field investigation in large cities throughout China thus allows us not only to draw A Distributional Map of Pragmatic Features of the Title xiaojie(小姐) ,but also enables us to see its diachronic possibilities.展开更多

Methods： A549 cells in logarithmic proliferation were cultivated in RPMI-1640 containing 10% low, medium or high dosages of XJD serum. The inhibitive effect of XJD in A549 cell proliferation was assessed by methylthiazolyldiphenyl-tetrazolium bromide （MTT） assay. The pro-apoptotic effect of XJD in A549 cells was observed by fluorescence microscope via Hoechst 33258 staining. The role of the Akt signaling pathway was observed by examining the presence of p-Akt protein by Western blot and the mRNA expression of downstream proteins such as Bcl-2/BcI-XL-associated death promoter （BAD） and caspase-9 by real time polymerase chain reaction. Results： MTT assay revealed that XJD could inhibit A549 proliferation in a dose- and time-dependent manner. Hoechst 33258 staining showed that XJD induced the typical nuclear apoptotic morphology after XJD treatment. Moreover, XJD could reduce the phosphorylation of Akt and increase the mRNA expression of BAD and caspase-9. Conclusions： XJD can inhibit the proliferation of A549 cells in a dose- and time-dependent manner through signaling Akt pathway via up-regulating the expression of BAD and caspase-9. XJD may provide a novel therapeutic model for lung cancer and deserve further study.展开更多
