Dawson said kha-nyu is not exactly the same animal as its ancestor, but it exemplifies the evo-lutionary uncertainties that prompted University of Chicago paleobiologist David Jablonski in the 1980s to come up with the concept of the Lazarus effect as a cautionary tool in evaluating the fossil record.

虽然我们习惯称此类动物为「活化石」，但其实不论是腔棘鱼或老挝岩鼠，都和祖先不一样，就如同所有活在世上的生物，经历长期演化，只是演化的过程在化石记录中付之阙如，一度被误以为绝种而已。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

The anterior border of the sigmoid sinus corresponds to the line connecting the mastoid tip with the junction of temporo-squamosal -parietomastoid sutures, and its posterior border to the line connecting the mastoid tip with O point.

通过体表可扪及的外耳道上棘、乳突尖和枕外窿突，可对横窦、乙状窦边界进行体表定位，最大限度避免损伤静脉窦，使入路设计更为安全，术中视野更为开阔。
