Objective: To study the action mechanisms of Qinggan Huoxue Recipe (QGHXR), a compound traditional Chinese herbal medicine, and its separated recipes by observing their effects on expressions of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in rats with alcoholic liver fibrosis (ALF).
Methods: A total of 150 SD rats were divided into three groups: blank group, carbon tetrachloride (CCl4) group and ALF-inducing group. Rats in the ALF-inducing group were administered with a mixture diet (56% alcohol 10 mL/kg, corn oil 2 mL/kg, pyrazole 25 mg/kg) once daily and intraperitoneally injected with 0.3 mL/kg 25% solution of CCl4 in olive oil twice weekly. The CCl4 group was intraperitoneally injected with equal volume of CCl4 and olive oil as the ALF-inducing group and ingested normal saline (12 mL/kg per day). The blank group was intraperitoneally injected with and ingested saline in equal volumes of the above. At the end of the eighth week, the survived rats in the ALF-inducing group were divided into four subgroups: untreated group, QGHXR group, Qinggan Recipe (QGR) group and Huoxue Recipe (HXR) group. The three treated groups were given corresponding drugs respectively (4.75, 1.5, 3.25 g/kg). The blank group, CCl4 group and untreated group were given normal saline in equal volume (5 mL/kg per day). All rats were anaesthetized and killed at the end of the twelfth week. The activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum were analyzed. Pathological changes in liver tissues were observed by hematoxylin and eosin staining and Masson staining. The expressions of uPA and PAI-1 were evaluated with Western blotting, immunofluorescence, and real-time polymerase chain reaction.
Results: There existed obvious liver fibrosis in liver tissues in the untreated group as compared with the blank group (P<0.01), and the activities of ALT and AST and the expressions of uPA and PAI-1 also increased in the untreated group. QGHXR and its separated recipes could improve the degree of liver fibrosis (P<0.01). QGHXR and its separated recipes could degrade the activity of ALT as compared with the untreated group; QGHXR and its separated recipes advanced the expression of uPA, and decreased the expression of PAI-1 significantly as compared with the untreated group. The effect of QGHXR was the best among the three recipes.
Conclusion: QGHXR and its separated recipes may improve ALF in rats by decreasing the expression of PAI-1 and advance the expression of uPA. The effect of QGHXR is the best among them.
