title: [Effects of yiqi huayu recipe and its decomposed formulas on apoptosis-related factors of anulus fibrosus cells in rats].
abstract: OBJECTIVE
  To study the effects of Yiqi Huayu Recipe and its decomposed formulas-medicated sera on expressions of bcl-2, Bax and caspase-8 of apoptotic anulus fibrosus cells in rats.
  
  
  METHODS
  Immunohistochemical and integral optical density analytic methods were used to observe the effects of Yiqi Huayu Recipe-, Yiqi Recipe-, Huayu Recipe-medicated sera and insulin-like growth factor 1 (IGF-1) on the expressions of bcl-2, Bax and caspase-8 of apoptotic anulus fibrosus cells in rats induced by anti-Fas antibody.
  
  
  RESULTS
  As compared with apoptosis group, bcl-2 expression was higher, Bax and caspase-8 expressions were lower in Yiqi Huayu-treated, Yiqi-treated, Huayu-treated and IGF-1 groups (P<0.01). As compared with Yiqi-treated group and Huayu-treated group, Bax expression was lower in Yiqi Huayu-treated group (P<0.05).
  
  
  CONCLUSIONS
  Yiqi Huayu Recipe and its decomposed formulas can delay degeneration of the cervical intervertebral disc, which may be due to its action in regulating the expressions of bcl-2, Bax and caspase-8.
