Result:No significant difference was found in proliferation index,apoptosis index and PCNA/PARP ratio of chondrocytes and histological grades of cartilage in the inferior facet processes between convex and concave side in AIS(P>0.05).

• 采用PCNA/PARP比值及组织学分级作为软骨内成骨活跃程度的指标；并对其进行比较。 结果:AIS患者上、下端椎和顶椎凸、凹侧下关节突软骨组织学分级、软骨细胞的增殖指数(PCNA)、凋亡指数(PARP)和PCNA/PARP比值的比较均没有统计学差异(P>0.；05)。
