title: [Effect of jiangu erxian pill on proliferation and cell cycle of human osteoblast].
abstract: OBJECTIVE
  To further explore the effect of Jiangu Erxian Pill (JGEXP) on proliferation and cell cycle of human osteoblast on the basis of previous clinical and experimental studies.
  
  
  METHODS
  Human primary osteoblast were isolated and cultured. The cell proliferation was tested by 3H-thymine incorporation and methyl thiazolyl tetrazolium (MMT) method and the cell cycle was determined by flow cytometry technique.
  
  
  RESULTS
  In the medium and high dosage JGEXP groups, the cell proliferation rate and index, and percentage of diploid synthesis phase (S phase) cells were significantly higher than those in the blank control group (P < 0.01 or P < 0.05), and similar to those in the estrogen group; and the cell apoptosis rate and percentage of G0-G1 stage cells were lower than those in the blank control group (P < 0.01 and P < 0.05).
  
  
  CONCLUSIONS
  JGEXP could effectively promote the cell proliferation and differentiation, and prevent the cell apoptosis of osteoblast in vitro.
