Methods: A total of 90 patients with chronic gastritis were randomly divided into control group and observation group (n=45) according to the lottery method. Both groups were treated with conventional therapy. On this basis, the control group was treated with triple therapy. The observation group was treated with triple therapy combined with Wei Su granule. The levels of COX-2, E-cadherin, procalcitonin and gastrin in peripheral blood were measured before and after treatment in all subjects. Result: There was no significant difference in the levels of gastric mucosal COX-2 and E-cadherin between the two groups before treatment. After treatment, the levels of COX-2 and E-cadherin in both groups were significantly lower than those before treatment. And the observation group was lower than the control group after treatment. There was no significant difference in serum PCT and gastrin levels between the two groups before treatment. After treatment, the levels of PCT and gastrin in both groups were significantly lower than those before treatment. And the observation group was lower than the control group after treatment. Conclusion: Wei Su granule combined with triple therapy in the treatment of chronic gastritis, can effectively reduce the levels of COX-2, E-cadherin, PCT and gastrin, relieve the gastric mucosal injury and symptoms, which is a clinically effective treatment.展开更多

Within 60 min after feeding, the level of cucurbitacin C in fed coty-ledons of the cucumber seedling increased 10 fold or more. Cucurbitacin I was also detected 15 min after feeding, which reached 75 mg/g within 60 min. The high levels of cucurbi-tacins C and Ⅰ in fed cotyledons could be maintained for at least 24 h. A. femoralis chinensis was strongly stimulated to take food by cucurbitacin C at a concentration between 10 and 250 mg/g, and the feeding deterrent activity was observed at >250 mg/g, while the feeding deterrent threshold of A. femoralis chinensis to cucurbitacin I was 50 mg/g. The mix-ture of cucurbitacins C and Ⅰ had a much stronger feeding deterrent activity than single cucurbitacin I. The results suggested that cucumber could elicit chemical response to the beetle herbivory, its leaf being induced to produce more kinds of cucurbitacins and make them reach the levels of feeding deterrent activity on the beetle, while the trenching behavior of A. femoralis chinensis was its strategy to answer the chemical response of cucumber. The trenching behavior of the beetle not only stopped the cucurbitacins biosynthesis in cucumber leaf tissues, but also blocked the translocation of cucurbitacins to the feeding sites. The trenching behavior of the beetle and the chemical response of host cucumber were the mutual adaptive strategies for protecting the host plant and the beetle themselves.展开更多
