But in early resorptive phase in GSB group. The change of BMD, BGP, D-Pyr/Cr and biomechanics index in OVX-PII group were the same as that in OVX-PI group, but the rising range of compressive strength limit in lumbar spine and bend load of femur is bigger than that of JGG, and GSB group. Dynamics osteoblast appeared in large numbers on the surface of os, we can observe the transforming process from osteoblast to osteocyte.

METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide or caspase-3 inhibitor (DEVD-CHO, 100 μmol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and IκΒ-α were detected by Western blotting methods.
