细胞衰老是细胞经过一定增殖代数后进入特定G1期生长阻滞，但保持生理生化活性的现象；它是生物进化的结果，也是个体抗癌变的自我保护机制之一。

Cellular Senescence is the end of cell proliferation into irreversible G1 growth arrest after certain population doublings, but still maintaining the basic physiological and biochemical activities. It is a kind of cancer-protection mechanism originated from evolution.

细胞衰老是细胞经过一定增殖代数后进入特定G1期生长阻滞，但保持生理生化活性的现象；它是生物进化的结果，也是个体抗癌变的自我保护机制之一。

Plant polyprenols, which have similar structure and biological activity to dolichols in human body, are lipids of polymer with isoprenyl units. However, dolichols are key carriers in biosynthesis process of glycosyl derivatives with protein.

植物聚戊烯醇是一类异戊烯基结构聚合体的类脂化合物，与人体内多萜醇具有相似的结构特征和生理活性，而多萜醇是糖基与蛋白质生物合成的关键载体。

Cases recovered completely, and some various complications occurred in 14 cases. Conclusion Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress. This device corresponds to the biomechanics of the spinal column. But during the operation, complications should be avoided or diminished by performing strict aseptic technique, bending of the rod to a proper physiological curvature which corresponds to injured spine, doing posterior bone grafting and using corset support after operation.

结论哈氏棒是一种符合生物力学的内固定器材，具有较强的纵向撑开力，能使骨折脱位得到很好复位，但亦具有一些缺点，如术中能做到置钩前预制好骨孔，并将哈氏棒预弯成与伤段脊柱相应的生理弧度，加用钢丝固定双棒，行后路植骨融合，术后使用支架保护，严格无菌操作等，可大大降低并发症的发生。
