abstract: OBJECTIVE
  To study the dynamic changes of blood hormone levels in H22 liver cancer mice of poisonous pathogenic factors syndromes (PPFS) to different degrees.
  
  
  METHODS
  Two hundred and twenty mice were injected with H22 tumor cells from their armpits. On the ninth day after inoculation the mice of severe poisonous pathogenic factors syndrome (SPPFS) and of mild poisonous pathogenic factors syndrome (MPPFS) were screened. Besides, another normal control group consisting of 30 mice was set up. The mice were killed on the tenth and eleventh day after inoculation (as the 1st and 2nd time window). The weight of the tumor, the wet weight of the thymus and the spleen were weighed. The plasma adrenocorticotropic hormone (ACTH), corticosterone, aldosterone, thyroid hormone T3 and T4, testosterone, TNF-alpha, and IFN-gamma were detected by ELISA. All the aforesaid laboratory parameters were analyzed.
  
  
  RESULTS
  The tumor weight was obviously larger in mice of the SPPFS group than in those of the MPPFS group at the same time window (P < or = 0.05). Compared with the normal control group, the thymus was obviously atrophied (P < or = 0.05), the spleen was significantly enlarged (P < or = 0.05), the plasma ACTH significantly increased (P < or = 0.05) in the SPPFS group at the two time windows. But the increment of ACTH was less in the MPPFS group. The plasma corticosterone showed similar tendency as that of ACTH. At the 1st time window the plasma testosterone significantly increased in the two groups (P < or = 0.05). The plasma testosterone and T4 showed a decreasing tendency in the SPPFS group. The plasma TNF-alpha and IFN-gamma levels showed an increasing trend in the two groups. Correlation study showed that the degree of PPFS was negatively correlated with qi deficiency (r = -0.766, P < or = 0.05) and T4 (r = -0.738, P < or = 0.05). The degrees of PPFS was positively correlated with the plasma ACTH level (r = 0.635, P < or = 0.05). The degree of qi deficiency was positively correlated with yang heat syndrome (r = 0.632, P < or = 0.05). The plasma ACTH was negatively correlated with T4 (r = -0.504, P < or = 0.05). The plasma testosterone was positively correlated with TNF-alpha (r = 0.619, P < or = 0.05).
  
  
  CONCLUSIONS
  PPFS occurs naturally and shows difference to different degrees in the development of H22 liver cancer. The disorders of neuroendocrine hormones and the suppression of the immune function show dynamic changing trends.
