title: [Therapeutic effect of weikangfu on gastric precancerous disorder with spleen deficiency syndrome and its effect of gastric mucosal zinc, copper, cyclic adenosine monophosphate, superoxide dismutase, lipid peroxide and 3H-TdR lymphocyte conversion test].
abstract: OBJECTIVE
  To observe the clinical therapeutic effect of Weikangfu granule (WKF) on intestinal metaplasia (IM), atypical proliferation (ATP) and its therapeutic mechanism.
  
  
  METHODS
  Sixty-one patients (treated group) were diagnosed by integrated TCM and western medicine (WM), and treated according to Syndrome Differentiation, the amount of WKF was adjusted according to various Syndromes. The control group consisted of 54 patients, took Weisu granule without considering their Syndromes. Besides, 15 healthy subjects comprised of the control group. Gastroscopy was conducted both before and after the treatment, mucosal sample was taken from antral region of stomach for pathological changes, for IM classification through histochemical staining and for determination of gastric mucosal Zn, Cu, cAMP, SOD, serum LPO and 3H-TdR lymphocyte conversion test (LCT).
  
  
  RESULTS
  (1) The symptomatic and pathologic therapeutic effect of the treated group were markedly better than those of the control group (P < 0.05, P < 0.01). (2) The levels of gastric mucosal Zn, Cu, cAMP, SOD and 3H-TdR LCT of the treated group before treatment were all lower than that of the healthy control group, but they were markedly increased after treatment, while serum LPO, however, increased before treatment, significant difference existed between the above groups (P < 0.05, P < 0.01).
  
  
  CONCLUSIONS
  WKF can reverse IM and ATP of Spleen Deficiency Syndrome through the mechanism of improving the level of gastric mucosal Zn, Cu, cAMP and SOD, promoting cytodifferentiation, improving cytoimmunity, reducing superoxide and LPO.
