结论
2
茵芪三黄解毒汤可能通过抑制Piezo1/PI3K/AKT信号通路,促进巨噬细胞由促炎的M1型向抗炎的M2型极化,发挥抗肝纤维化的作用。
Objective
2
To investigate the effect and mechanism of
Yinqi Sanhuang Jiedu Decoction
(茵芪三黄解毒汤, YSJD) in impoving liver fibrosis based on the mechanosensitive ion channel protein 1 (Piezo1)/ phosphatidylinositol 3-kinase (PI3K)/ protein kinase B (AKT) pathway.
Methods
2
Fifty C57BL/6J mice were randomly divided using a random number table into a control group, a model group, and low-, medium-, and high-dose YSJD groups, with 10 mice in each group. Except for the control group, mice received intraperitoneal injections of 10% CCl
4
twice weekly for 6 weeks to establish the liver fibrosis model. On the day after modeling completion, the low-, medium-, and high-dose YSJD groups were administered YSJD suspension via oral gavage at doses of 3.79, 7.58, and 15.16 ml/(kg·d), respectively, once daily for 8 weeks. The control and model gr
oups received an equal volume of normal saline. On the day after the final administration, liver stiffness was measured by ultrasound imaging; liver tissue Young's modulus was detected by atomic force microscopy; liver histopathological morphology was assessed by HE staining; collagen deposition was evaluated by Sirius red staining; serum liver function, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL) and four liver fibrosis markers, namely laminin (LN), hyaluronic acid (HA), type Ⅲ procollagen (PC-Ⅲ), type Ⅳ collagen (C-Ⅳ), were analyzed using an automatic biochemical analyzer; the M1/M2 ratio in liver tissue was detected by flow cytometry; mRNA expression of transforming growth factor-β1 (

), α-smooth muscle actin (

-
SMA
), type Ⅰ collagen (
collagen
-Ⅰ), inducible nitric oxide synthase (
iNOS
), tumor necrosis factor-α (

-
α
), arginase 1 (
Arg
-

), and mannose receptor (
CD206
) in liver tissue was measured by real-time quantitative PCR; protein levels of Piezo1, phosphorylated PI3K (p-PI3K), PI3K, phosphorylated AKT (p-AKT), and AKT were detected by Western Blot.
Results
2
Compared with the control group, the model group showed increased liver stiffness and Young's modulus (
P
<0.01), disordered liver structure and increased collagen fiber deposition ratio (
P
<0.01), elevated serum levels of ALT, AST, TBIL, DBIL, HA, PC-Ⅲ, and M1/M2 ratio, increased mRNA expression of

P
<0.01). The high-dose YSJD group was superior to the low-dose group in improving liver stiffness, liver Young's modulus, collagen fiber deposition ratio, ALT, DBIL, HA, PC-Ⅲ, M1/M2 ratio, mRNA expression of

Conclusion
2
YSJD may exert anti-liver fibrosis effects by inhibiting the Piezo1/PI3K/AKT signaling pathway, thereby promoting macrophage polarization from pro-inflammatory M1-type to anti-inflammatory M2-type.
