This work investigated the protein expression levels of moving rat liver under the exposure of PM2.5  by using different loading swimming training modes. The result provides a theoretical basis for the effects of aerobic exercise on liver function in the exposed environment of PM2.5. The rat training modes under the PM2.5  exposure were set up as follow:

PM2.5

exposure section (E)

low exposure section (LES)

middle exposure section (MES) and high exposure section (HES) Elisa method was applied to detect the expression level of TNF-α and Western blot assay was used to evaluate the protein expression of PPAR-γ.   The results showed that the TNF-α of MES was lower than that of other sections with the -effective-statistical significance at

P

<

0.05. The  PPAR-γ expression levels of LES and MES were significantly higher than that of E with the effective statistical significance at P

<

0.05. Therefore

under the exposure of PM2.5

moderate-intensity training could effectively stimulate the cell factor and promote the signal deliver between Islet cell

as a result

the functions of the liver can be influenced.
