Effects of Xuefu Zhuyu Capsules (血府逐瘀胶囊) on Aortic Lesion and Expression of CD47, PPARγ and NR1H3 in Atherosclerosis Model Mice
(blood lipids) in the treatment of atherosclerosis (AS).
Methods
2
Thirty apolipoprotein E knockout (ApoE
-/-
) mice were randomly divided into model group,
Xuefu Zhuyu Capsules
(血府逐瘀胶囊) group and atorvastatin group, with 10 mice in each group, and 10 C57BL/6N mice were set as normal control group. Except for normal group, mice in other groups were fed with high fat diet for six weeks to prepare early AS model. After successful modeling, the drug groups were given
Xuefu Zhuyu Capsules
(0.6g·kg
-1
·d
-1
) and atorvastatin (3.3 mg·kg
-1
·d
-1
) by gavage, respectively. The normal and model groups were given 0.3 ml of deionized water by gavage. After 12 weeks of intervention, the pathological changes and lipid deposition of aortic valve in mice were observed. Blood lipid indexes including serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected, and TC/HDL-C, LDL-C/HDL-C, and atherosclerosis index (AI) were calculated. The protein expression levels of aortic signal transducer integrin-associated protein (CD47), peroxisome proliferator-activated receptor γ (PPARγ) and liver X receptor α (NR1H3) were detected by western blot.
Results
2
Compared to those in the normal group, the aortic valve plaque area and lipid deposition of mice in the model group increased, while serum TC, LDL-C, TC/HDL-C, LDL-C/HDL-C and AI levels, as well as aortic CD47 protein expression increased, and HDL-C level decreased (
P
<0.01). Compared to those in the model group, the aortic valve plaque area and lipid deposition in the
Xuefu Zhuyu Capsules
group and the atorvastatin group decreased, while the serum TC and LDL-C levels and CD47 protein expression decreased, and the NR1H3 protein expression increased (
P
<0.01); moreover, the expression level of PPARγ protein in
Xuefu Zhuyu Capsules
group increased (
P
<0.01), while the level of HDL-C increased in atorvastatin group, and TC/HDL-C, LDL-C/HDL-C and AI were significantly reduced (
P
<0.05 or
P
<0.01). Compared to that in the atorvastatin group, the expression level of CD47 protein in
Xuefu Zhuyu Capsules
group increased (
P
<0.05).
Conclusion
2
The treatment of AS by
Xuefu Zhuyu Capsules
may be related to the expression of key molecules regulating inflammation, which are CD47, PPARγ, and NR1H3.
