[Progress on tendon-to-bone healing after rotator cuff repair].

Rotator cuff tear is a common disease that causes shoulder pain and limitation of activity. Rotator cuff repair with arthroscope has become the mainstream method with advance in surgical techniques. In spite of this, the highly rate of retear after surgery mainly because the tendon to bone interface form scar tissue rather than native tissue.

Effects of paclitaxel on proliferation and apoptosis in human acute myeloid leukemia HL-60 cells.

Aim: To investigate the regulatory effect of paclitaxel on proliferation and apoptosis in human acute leukemia HL-60 cells.

Methods: HL-60 cell growth was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tertrazolium bromide (MTT) colorimetric assay. Cell cycle kinetics and apoptosis were analyzed by flow cytometry and microscopic examination.
