Objectives: To measure the expression of matrix metalloproteinase (MMP)-2, tissue inhibitor of matrix metalloproteinase inhibitor (TIMP)-2, and CD147 in mice with chronic liver injury induced by carbon tetrachloride after treatment with the traditional Chinese medicine (TCM) “Compound T11”. Method: Sixty male ICR mice were divided randomly into 6 groups of 10: control (C), model (M), low-dose treatment (LT; 50 mg/mL of Compound T11), medium-dose treatment (MT, 100 mg/mL), high-dose treatment (HT, 150 mg/mL), and positive drug treatment (YT, 67.5 mg/mL). Each group was modeled for 7 weeks. Groups M, LT, MT, HT, and YT were injected (s.c.) with 20% carbon tetrachloride diluted with olive oil, and group C was given olive oil in the same way twice a week. After modeling, the treatment groups were administered Compound T11 at the concentrations shown above by oral gavage daily for 2 weeks, while group C was given 0.5% carboxymethyl cellulose sodium. After the final treatment, mice were killed and their liver tissues were excised. Immunohistochemical staining was performed to measure the protein expression of MMP-2, TIMP-2, and CD147, and western blotting was used to measure the protein expression of MMP-2, TIMP-2, CD147, and α-smooth muscle actin (SMA). MMP-2, TIMP-2, and CD147 mRNA expression was determined by quantitative fluorescence real-time PCR. Results: Compound T11 increased the protein expression of MMP-2 and CD147 and decreased the protein expression of TIMP-2 and α-SMA. Conclusions: Treatment of chronic liver injury by TCM Compound T11 may be associated with changes to the expression of MMP-2 and CD147, and the inhibition of TIMP-2 expression.
