[Study on Regulation Effects of Yiqiyangyin Formula on Advanced Lung Cancer Cachexia Mice]

To observe the effect of Yiqiyangyin formula on advanced lung cancer cachexia mice.

60 C57 BL /6inbred mice( SPF) were randomly divided into normal control group, model group, Yiqiyangyin formula group,indomethacin group, and cisplatin group, with 12 mice in each group. Model group and normal control group were treated with the same amount of normal saline. Except for the normal control group, the mice of the other groups were built with Lewis lung cancer model. The changes of the level of body mass, feed consumption,serum cytokine,the expression of TNF-α and its receptor were observed.

After eight days of treatment, compared with cisplatin group, the levels of CEA,NSE,Pro GRP in serum,CD3+,CD4+,CD4+/ CD8+levels in serum peripheral blood and TNF-R1 expressions in tumor tissues of Yiqiyangyin formula group were increased( P < 0. 05),the contents of TNF-α and IL-6 and the expressions of TNF-α and TNF-R2 in tumor tissues of Yiqiyangyin formula group were significantly decreased( P <0. 05).

Yiqiyangyin formula affects on advanced lung cancer cachexia, which may be related to the regulation of the immune and inflammatory cytokines expression.
