Abstract: Panax japonicus polysaccharide (PSPJ), prepared via water extraction and alcohol precipitation,
was used for treatment of rats with CCl 4-induced acute liver injury (ALI). The mechanism of PSPJ's
intervention on the injury through PI3K/AKT/NF-κB signaling pathway was analyzed by observing and
recording the general condition and liver index (liver mass/body mass) of rats. The effects of PSPJ on the
pathological changes of liver tissue were evaluated by hematoxylin-eosin (H&E) staining,
immunohistochemical (IHC) staining for the liver NF-κB expression, and protein immunoblotting (Western
blot) analysis on the expression levels of PSPJ on PI3K/AKT/NF-κB signaling pathway related proteins and
inflammatory indexes in ALI rats. The results showed that compared with the blank control group, the
model group exhibited significant increment in the body mass, liver mass as well as liver index (P<0.05,
indicating statistical significance, the same below), and a large number of liver tissue inflammatory
infiltration, while the drug treated group displayed obvious relief in the liver pathological changes.
Compared with the blank control group, the protein expression of p-PI3K in liver tissue of model group was
significantly decreased (P<0.01), while the protein expressions of PI3K, p-AKT, p-NF-κB and IL-1β were
