ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Jianpi Qingre Huayu Recipe in curing gastric ulcer and to preliminarily probe into its pathogenic mechanism.</p><p><b>METHODS</b>Fifty patients with gastric ulcer of Pi -insufficiency and stasis-heat syndrome type were assigned to the treated group (30 patients) and the control group (20 patients). They were treated respectively with JQH and Ranitidine. At the same time, another group consisting of 20 healthy persons was set up for normal control. The clinical effect on gastroscopic figure and traditional Chinese medicine (TCM) syndrome were observed. Changes of T-cell subsets and interleukin-8 (IL-8) in serum as well as IL-8 in mucosa around the gastric ulcer were determined before and after treatment by flow cytometry and ELISA.</p><p><b>RESULTS</b>Comparison of the total effective rate on gastroscopic figure in the treated group and the control group (86.7% vs 80.0%) showed insignificant difference, but the cure rate and markedly effective rate in the former (50.0% and 20.0%) was higher than that in the latter (40.0% and 15.0%) respectively. Comparison of the total effective rate on TCM syndrome in the treated group and in the control group (96.7% vs 70.0%) showed insignificant difference, but the cure rate and markedly effective rate in the former (63.3% and 23.3%) was higher than that in the latter (50.0% and 20.0%) respectively. Serum levels of CD3+, CD4+, CD8+ got restored to normal range in the treated group after treatment but it was not so in the control group. IL-8 level in gastric mucosa was improved in both groups but the improvement in the treated group was better.</p><p><b>CONCLUSION</b>JQH could effectively treat gastric ulcer and partly reduce its recurrence through improving patients' immune function.</p>
