Abstract
Objective:
2
To investigate the protective mechanism of Liuwei Dihuangwan on diabetes mellitus with liver injury in terms of inflammation.
Method:
2
The 18 db/db mice were selected from animal model of spontaneous type 2 diabetes
mice were randomly divided into model group
Liuwei Dihuangwan group(9.75 g·kg
-1
·d
-1
once a day)
resveratrol group(42.6 mg·kg
-1
·d
-1
once a day)based on fasting blood-glucose (FBG). The 12 litter wild db/m mice were randomly divided into normal group
Liuwei Dihuangwan group(9.75 g·kg
-1
·d
-1
once a day). The normal group and the model group were given the same amount of distilled water by gavage. The mice in each group were treated for 16 weeks. FBG
triglyceride (TG) and alanine aminotransferase (ALT) were examined. Histopathological changes were observed by liver biopsy hematoxylin-eosin (HE) staining. Silent information regulator 6 (SIRT6)
nuclear factor-kappaB p65 (NF-
κ
B p65)
monocyte chemoattractant protein-1 (MCP-1)
vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) in the liver tissue were detected by Western blot.
Result:
2
Compared with normal group
FBG
TG and ALT in model group increased significantly(
P
<
0.01)
protein expression levels of NF-
κ
B p65
MCP-1
VCAM-1 and ICAM-1 in model group were significantly up-regulated(
P
<
0.01)
the protein expression level of SIRT6 in model group was significantly down-regulated(
P
<
0.01). Compared with model group
Liuwei Dihuangwan and resveratrol could significantly reduce the levels of serum FBG and TG(
P
<
0.01)
the protein expression of SIRT6 was significantly increased(
P
<
0.01)
NF-
κ
B p65
MCP-1 and VCAM-1 were significantly decreased (
P
<
0.05
P
<
0.01)
and liver steatosis and inflammatory cells infiltration were alleviated.
Conclusion:
2
Liuwei Dihuangwan can protect the diabetes mice from liver injury
and its mechanism is related to the improvement of lipid metabolism and the inhibition of inflammatory response.
