简要总结
The goal of this clinical trial is to learn if drug Chazhu Xiaozhi decoction works to treat non-alcoholic fatty liver disease in adults. It will also learn about the safety of drug Chazhu Xiaozhi decoction. The main questions it aims to answer are:
Does drug Chazhu Xiaozhi decoction improve the degree of hepatic steatosis in patients with non-alcoholic fatty liver disease? What medical problems do participants have when taking drug Chazhu Xiaozhi decoction? Researchers will compare drug Chazhu Xiaozhi decoction to a placebo (a look-alike substance that contains no drug) to see if drug Chazhu Xiaozhi decoction works to treat non-alcoholic fatty liver disease.
Participants will:
Take drug Chazhu Xiaozhi decoction or a placebo every day for eight weeks Keep a record of their symptoms and the degree of hepatic steatosis before and after the treatment

盲法说明
The control placebo is a ten-fold dilution of the Chazhu Xiaozhi decoction, supplemented with colorants and bittering agents to mimic the appearance and color of the treatment drug. An independent researcher (not involved in the trial operations or evaluations) is responsible for managing the randomization sequence and drug coding, and will distribute the appropriate drugs to participants at the right times. This ensures that the trial operators and evaluators are unaware of the treatment type; only the independent researcher has this knowledge. During the experiment, the assessment of treatment effects and the recording of adverse events are carried out by independent evaluators who are unaware of the treatment groups. Both the trial operators and the evaluators do not have access to the drug coding and randomization sequence.

结局指标
主要结局
traditional Chinese medicine syndrome scale
时间窗: through study completion, an average of 8 weeks
The traditional Chinese medicine syndrome scale includes evaluations of symptoms such as discomfort in the right flank, bloating in the epigastric region, bitter mouth, dry mouth, loose and loose stools, fatigue and fatigue throughout the body, loss of appetite, nausea, dizziness, and yellow urine, with a score range from 0 to 3, and higher scores mean a worse outcome.
controlled attenuation parameter
时间窗: through study completion, an average of 8 weeks
A liver fiber diagnostic instrument (Fibro Touch) is used to perform instantaneous elastic hardness testing. The controlled attenuation parameter usually represents liver fat content, whereas higher scores mean a worse outcome.
