The percentage of Ki67-positive cells was compared with the median number of mitotic figures per square millimeter. Both Ki67 positivity and the number of mitotic figures were found to be greater in high grade than in low grade lymphomas, although there was an overlap between the two grades of malignancy. A close correlation was found between the number of mitotic figures and the percentage of Ki67-positive cells not only in all lymphoma typo taken together (r_s= 0. 834 . P<0. 001). but also in B-cell lymphoma (r_s= 0. 8 1 P< 0. 001) and T-cell lymphoma (r_s = 0. 764. P<0. 00 1) taken seprately. Thus, both methods are useful for the estimation of proliferative activity. but each method has its advantages and disadvantages.展开更多

From the aspect of observation, the PMOI can be calculated from the spherical coefficients of observed gravity field. In this paper, the PMOI are calculated directly according to its definition with the figures of the Earth＇s interior derived by a generalized theory of the hydrostatic equilibrium figure of the Earth. We obtain that the angle between the principal axis of the maximum moment of PMOI and the rotational axis is 0.184~, which means that the other two principal axes are very closely in the equatorial plane. Meanwhile, B-A is 1.60 x 10-5 MR2, and the global dynamical flattening （H） is calculated to be 3.29587 ~ 10-3, which is 0.67% different from the latest observation derived value Hobs（3.273795 × 10 ^-3） （Petit and Luzum, 2010）, and this is a significant improvement from the 1.1% difference between the value of H derived from traditional theories of the figure of the Earth and the value of Hobs. It shows that we can calculate the PMOI and H with an appropriate accuracy by a gener- alized theory of the hydrostatic equilibrium figure of the Earth.展开更多

More and more domestic and overseas scholars published their translated texts on Neijing. Due to the diversity of editions and different understanding, the translating styles and contents are widely different. This study will focus on the different translating styles on culture-specific lexicon、figure of speech and four-Chinese-character structures in Neijin.展开更多
