[Clinical study of weishu capsule in treating precancerous lesions of chronic atrophic gastritis].
OBJECTIVE
To explore the therapeutic effect and mechanism of Weishu capsule (WSC) in treating precancerous lesions of chronic atrophic gastritis (CAG).


METHODS
Seventy-five cases of precancerous lesions of CAG were distributed to two groups randomly, the treated group (45 patients) treated with WSC by taken orally and the control group (30 patients) treated with Weining granule (WNG) orally. The treatment course of both groups were 6 months. The clinical and pathological effects and the changes in scores of atrophy, intestinal metaplasia and its subgroups, dysplasia, carcinoembryonic antigen (CEA) and proliferating cell nuclear antigen (PCNA) expression were observed before and after treatment.


RESULTS
The total effective rate was 91% and the effective rate of atrophy, intestinal metaplasia, dysplasia in the treated group were 64%, 67% and 65% respectively, and the respective scores were lowered significantly after treatment. Compared with the control group the difference between the two groups was statistically significant (P < 0.01, P < 0.05). Immunohistochemical test showed that WSC could inhibit the subgroups of intestinal metaplasia, CEA and PCNA expression significantly (P < 0.01).


CONCLUSIONS
WSC could significantly improve the clinical and pathological changes in the precancerous lesions of CAG. The mechanism might be related to the inducing and promoting effect of WSC on the differentiation and maturity of intestinal metaplasia cells and dysplasia cells. WSC could also inhibit and correct the abnormal proliferation of cells.
