Patients who normally appear blue or dark, if they appear in a short period of time, patients need to actively check liver function and perform liver function tests to draw blood in a fasting state. If the patient suggests elevated glutamic and glutamic aminotransferases, and has elevated bilirubin. In this case, the patient should consider the possibility of other diseases, such as viral hepatitis, and the patient needs to check the hepatitis B triple system or hepatitis C antibody at the same time. If the patient has viral hepatitis and liver function impairment, further investigation of hepatitis B DNA or hepatitis C RNA is required to see if the virus is replicating. If the virus is replicating and there is a combination of liver function impairment and elevated glutamate and glutamic acid aminotransferase. At this time, the patient should consider active antiviral treatment, either oral medication or interferon injection for antiviral. This can be supplemented with hepatoprotective therapy, including intravenous infusion of reduced glutathione and thiopronine, and with aggressive antiviral therapy. Patients usually improve after 1-2 months of treatment, and they should pay attention not to drink alcohol, stay up late, or work hard.
