Objective To investigate the effect of Intedeukin-18 (IL-18) on Th1/Th2 balance and its antitumor mechanism in C57BL/6 mice Lewis lung cancer model. Methods 24 C57BL/6 mice were randomly divided into three equal groups: group A(IL-18 injec-tion group, n = 8), group B (Lewis lung cancer model, n = 8) and group C (normal control group, n = 8). The Lewis lung cancer cells were cultured and implanted subcutaneously into the group A and group B. IL-18 and NS were given to group A and B respectively by intrap-eritoneal injection on the 7th day (once every day, 7 times altogether), but group C was not given any treatment. Enzyme-linked immunosor-bent assay (ELISA) was used to detect the Th1/Th2 cytokines. Health status in all the animals was evaluated; the volume and weight ofsubcutaneous tumors were measured. Results The concentration of IFN-γ in group A and C were significantly higher than those in group B (P <0.05), and the concentration of IL-4 in group A and C were significantly lower than those in group B (P<0.05), but there was no significant difference between group A and C (P>0.05). The tumor growth inhibitory rate was 75%. Conclusion IL-18 can effectively induced IFN-γ and inhibit IL-4 production, regulate Th1/Th2 balance in the C57BL/6 mice Lewis lung cancer model, and elicit the antitu-mor immunity of the host, which could obviously inhibit the growth of tumor cells and decelerate the proliferation of tumor cells.

Currently, cardiovascular disease has become a major threat to the health of Chinese residents, and prevention and control work is urgent. Self-determination theory is a widely applied theory of behavioral change, extensively used in the field of patient' rehabilitation. This article reviews the content, relevant theoretical models, motivation measurement methods, application status and influencing factors of self-determination theory in the rehabilitation of cardiovascular disease patients, so as to provide a basis for promoting the transition of cardiovascular disease patients to healthy lifestyles and maintaining healthy behavior.
