()The main pathology an

20、d pathogenesis in liver disease progression includes liver inflammation, fibrosis, cirrhosis and liver failure, etc.()All-round accessorial tests can be used to evaluate liver damage degree of inflammatory, with the elevated serum ALT as the most commonly used indicator. However, it is so far contro

()Although anti-inflammatory therapy is a part of comprehensive treatments for liver inflammation, it cannot replace of antiviral therapy on the etiologies, etc. Conversely, etiological treatment such as

22、 antiviral therapy cannot completely replace the anti-inflammatory therapy. (),Recommendations,Regardless of whether there is an effective etiological treatment, it is necessary to implement the anti-inflammatory therapy in inflammation-induced liver disease, ()particularly in the liver disease that

23、 lacks effective etiological therapy. ()As anti-HBV or HCV therapy cannot control liver inflammation rapidly and directly, including elevated serum ALT, anti-inflammatory therapy should be given simultaneously. ()As the pharmacological effects of anti-inflammatory drugs or protectants have different

24、 features, the clinicians are suggested to choose proper drugs according to the characteristics of various liver inflammations and the drugs pharmacological effects. ()As various anti-inflammatory drugs have different functional features, and their combinations may obtain better efficacy, including

25、the drugs of anti-inflammation and liver protectant, including glycyrrhizic acid)and liver protectants. ()When patients with CHB and CHC are using anti-viral therapy, treatments using anti-inflammation or liver protectants should be considered, particularly in elevated serum ALT or obvious inflammat
