肉眼观察

Macroscopic observation: 4 weeks after the surgery, the defect was covered with tissue like cartage in the experimental group, and with periosteum in the control group.

肉眼观察：术后4周，实验组关节软骨缺损区被类软骨组织替代；对照组关节软骨缺损区仍被骨膜充填。

Light microscopic evaluationshowed that PMMA was in loose contact with the bone trabecula,PMMA could not be resorbed,and new bone could not be found.

肉眼观察：PMMA与松质骨界限清晰，一个椎体取材时交界面出现破碎和脱落现象；而CPC和rhBMP-2/CPC与椎体内松质骨界限不清，互相融合生长。

The surface of the post-core in the control groups were all oxygenized while those in the gilding groups had been oxygenized only near the margins of the cores and the upper 1/3 part of the post with uncontinuous and relatively thin layers.

肉眼观察：对照组桩核表面全部覆盖较厚黑色氧化层；镀金组近核边缘处和核下方桩颈1/3处有较薄散在的氧化层。

It's rather showy.I'd like something plainer.

赶花了，我想要素净些的。
