title: [Inhibitory effect of huangqi and dangshen extraction with pacilitaxel on metastasis and angiogenesis on mouse Lewis lung carcinoma model].
abstract: OBJECTIVE
  To study enhance effect of huangqi and dangshen extraction (Shenqi) on pacilitaxel inhibitory metastasis and angiogenesis on mouse Lewis lung carcinoma model.
  
  
  METHODS
  Lewis lung carcinoma cells were inoculated into right hind footpad of C57BL/6 mice. Six hour after tumor inoculated, the mice were randomly divided into 3 groups.Shenqi (paclitaxel plus Shenqi) or paclitaxel was intraperitoneally injected in two group since the second day of the establishment of animal model. The third group simply administered with normal saline was set as placebo-control. Tumor volume, quantitation of microvessel density (MVD) in inoculated tumor, the number of metastasis in the lungs and survival analysis were compared in 3 groups.
  
  
  RESULTS
  Paclitaxel plus Shenqi can effectively reduced MVD in inoculated tumor and the number of lung metastasis as compared with other two group (P<0.05). The survival time of Shenqi group was also significantly longer (P<0.05). Tumor volume was no statistical difference in three group (P>0.05).
  
  
  CONCLUSIONS
  Shenqi can amplify the paclitaxel effect of anti-angiogenesis and anti-metastasis, enhances the survival time of mice bearing LLC, might has possible therapeutic applications in the treatment of lung cancer.
