The first stage : The dose of 1/2 grade DILI patients was 0.5, 1.0, 2mg / kg, the dose of CHB patients was based on the efficacy and safety results of DILI patients, The second stage:The dose was determined by the comprehensive consideration of the efficacy and safety trial results in the first stage ,both the dose volume was 2 mL, intramuscular injection (IM), once a day for 14 consecutive days, and the dose was calculated by the weight results of the last visit. basic treatment: receive Diammonium glycyrrhizate enteric-coated capsules at a dose of 150 mg 3 times a day. The Third stage: The dose of the Screen eligible subjects was determined by the results of the efficacy and safety trials in the first and second stages. The dose volume was 2 mL, intramuscular injection (IM), once a day for 28 consecutive days. The dose was calculated by the body weight results of the last visit. basic treatment: receive acetylcysteine injection (NAC),the dose was 8 g/d, once a day.
