YQ23 suppressed liver tumor intrahepatic and lung metastasis after major hepatectomy and partial I/R injury. Buffalo rats were sacrificed at 4 weeks after major hepatectomy and hepatic I/R injury to monitor tumor metastasis. (A) Intrahepatic and lung metastasis were detected in specimen at four weeks after major hepatectomy and partial I/R injury. (B) Histological features of intrahepatic and lung metastasis tumors at four weeks after hepatectomy and partial I/R injury with and without YQ23 treatment. (T = tumor; NT = Non-tumor).
