Intervention Effect of Qufeng Gutong Babu Ointment on Rat Model of Osteoarthritis with Cold-dampness Obstruction Based on PI3K/Akt Signal Pathway
To investigate the intervention effect of Qufeng Gutong Babu ointment (QFGT) on rats with osteoarthritis (OA) with cold-dampness obstruction, and preliminarily clarify its mechanism.
Method
2
SD male rats were divided into 6 groups, namely, the blank group, model group, positive control drug Huoxue Zhitong ointment (HXZTG) group (1.26 cm
2
·d
-1
), and low, medium, and high-dose QFGT group (75, 150, 300 mg·d
-1
). OA model was prepared by joint cavity injection of papain and
L
-cysteine. On the second day of modeling, climate factors were applied to establish an animal model of combination of disease and syndrome of OA rats with cold-dampness obstruction. Standard VonFrey fiber was used to evaluate the threshold of mechanical pain. Weight bearing difference score and joint function score of both hind limbs were recorded. Hematoxylin-eosin (HE) staining and safranine fixation green staining were used to observe the pathological changes and cartilage degeneration of rat knee joint. Immunohistochemistry (IHC) was used to detect the expression of interleukin-1
β
(IL-1
β
), interleukin-8 (IL-8), tumor necrosis factor-
α
(TNF-
α
), matrix metalloproteinase-9 (MMP-9), and cathepsin K (CTSK). Western blot was used to detect the protein expression of kinase B (Akt), phosphorylated protein kinase B (p-Akt), phosphatidylinositol 3-kinase (PI3K), nuclear factor 1 (NFATc1), MMP-9, and CTSK in T cells.
Result
2
Compared with the normal group, the model group showed significant mechanical pain sensitivity reaction after modeling (
P
<
0.01), and the weight bearing difference of both hind limbs and joint function score were significantly increased (
P
<
0.05,
P
<
0.01). Compared with the model group, both the high-dose QFGT group and the HXZTG group significantly reduced the mechanical pain sensitivity, weight difference, and joint function score of rats (
P
<
0.05,
P
<
0.01), and the medium-dose QFGT group also improved the joint function to a certain extent, and the degeneration of the knee joint cartilage of rats was significantly reduced (
P
<
0.05,
P
<
0.01). QFGT and HXZTG both inhibited the protein expression of IL-1
β
, IL-8, TNF-
α
, MMP-9, CTAK, PI3K, p-Akt, Akt, and other related proteins in articular cartilage of rats with OA to a certain extent (
P
<
0.05,
P
<
0.01).
Conclusion
2
QFGT can inhibit the release of inflammatory factors and matrix metalloproteinases by inhibiting the PI3K/Akt signal pathway in articular articular cartilage of rats with OA with cold-dampness obstruction, thus ultimately weakening local cartilage degeneration and improving joint function.
