The main questions it aims to answer are: Does HBOT decreases the fat content and fibrosis state of liver in adult MASLD patients? Does HBOT improves the liver function and metabolic condition in adult MASLD patients? Participants will: Receive HBOT for 20 times in 1 month or recerive regular drug; Visit the clinic for checkups and tests at the starting, ending of the therapy and 6 month after the therapy.
