Hepatocellular injury should be treated promptly with hepatoprotective therapy, which can be applied with hepatocyte-protective Chinese medicines, including hepatale or compound glycyrrhizin injection, as well as compound dichloroacetate diisopropylamine for injection. There are many causes of hepatocyte damage: one, the most common is caused by chronic viral hepatitis B. Anti-hepatitis B virus treatment should be performed as appropriate, along with the application of liver protection drugs. Second, it can also be seen in malignant tumors of the hepatobiliary and pancreatic systems, resulting in hepatocellular injury or liver injury caused by biliary stasis. Patients with malignant tumors, who have been undergoing intravenous chemotherapy for a long time, have drug-related liver injury, in which case they should be treated with active liver protection, discontinuing the drugs if necessary, and liver protection therapy is also very important, and they can eat more vitamin-rich foods appropriately.
