RESUMEN
Objective: Based on the establishment of experimental model of liver yin deficiency syndrome, the effects of total glucosides of Paeoniae Radix Alba on the syndrome model of liver yin deficiency syndrome in rats with chemical liver injury were studied. Methods: SPF male Sprague-Dawley rats weighing (200 ± 20) g, after adaptive feeding, were randomly divided into control group, model group, Yi Guan Jian group, and total glycosides of Paeoniae Radix Alba group. Except the control group, the rats in the other groups were intraperitoneally injected with 20% CCl4 olive oil solution, and then ig treated with Aconiti Lateralis Radix Praeparata, Zingiberis Rhizoma and Cinnamomi Cortex to establish liver yin deficiency syndrome model. The Yi Guan Jian group and the total glucoside of Paeoniae Radix Alba group were administered at the same time, once a day for 6 weeks. After 6 weeks, the body weight and anal temperature of the rats were measured, and the general state was observed. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), 6-keto-prostaglandin F1α (6-keto-PGF1α), plasma thrombosis content of B2 (TXB2), laminin (LN) and hyaluronic acid (HA) were measured, and the activity of liver tissue interleukin-6 (IL-6), IL-10, and tumor necrosis factor (TNF-α) were measured. The expression levels of phosphatidylinositol kinase (PI3k) mRNA, protein kinase B (Akt) mRNA and protein were determined and livers were taken for pathological examination of HE. Results: Compared with the model group, the scores of the total glucosides of Paeoniae Radix Alba group were significantly increased (P < 0.05), the body weight was significantly increased (P < 0.05), and the serum ALT and AST levels were significantly decreased (P < 0.01, 0.001). The cAMP/cGMP ratio was increased significantly (P < 0.01). The LN and HA of the liver tissue of the total glycosides group were significantly decreased (P < 0.05, 0.001). The content of TNF-α and IL-6 was decreased significantly (P < 0.001), the expression level of Akt protein was decreased significantly (P < 0.05), the expression of PI3K and Akt mRNA was decreased significantly (P < 0.05, 0.001), and liver pathological sections were improved. Conclusion: The extract of Paeoniae Radix Alba has the effect of protecting liver injury with yin deficiency syndrome, which may be the material basis of supplement liver yin of Paeoniae Radix Alba. Its mechanism of action may be related to anti-inflammatory, alleviate microcirculatory disorders, and regulate the balance of cytokines IL-6 and IL-10 by inhibiting the PI3K-Akt pathway.
