RESUMO
OBJECTIVE@#To explore the therapeutic effects and mechanisms of the combination of traditional Chinese medicine and western medicine on patients with peptic ulcers.@*METHODS@#One hundred and twenty patients were randomly divided into 6 groups. Another 10 patients as the control group were confirmed with no peptic ulcers by endoscope, but had digestive tract symptoms. The clinical effects were compared among each group after the one month treatment.@*RESULTS@#The clinical effects of the combination of Jianweiyuyang granules and ranitidine capsules were better than those of western medicine, with improvement in symptoms and syndrome (P 0.05). The combination of Jianweiyuyang granules and ranitidine capsules could significantly upregulate the expression of MUCSAC mRNA (P < 0.01), while downregulate the expression of ETAR mRNA (P < 0.01).@*CONCLUSION@#There is obvious advantage in treating peptic ulcers by the combination of Jianweiyuyang granules and ranitidine capsules, and its mechanisms may be to protect the gastric mucosal barrier by up-regulating the expression of MUCSAC mRNA and to improve the gastric mucosal blood flow by down-regulating the expression of ETAR mRNA.
