Dr. Zheng had founded the PERSONS platform and has dedicated to the development of its infrastructure since 2016-12-07. PERSONS is the acronym for Prospective Epidemic Research Specifically of Non-Alcoholic Steatohepatitis. The database is an ongoing prospective cohort consisting of more than 930 cases of biopsy-proven non-alcoholic fatty liver disease (2019-07-01) and supported by a multidisciplinary team. The team boasts its advantage in patient data collection across multiple fields of medicine including nutrition, sports, hepatology, endocrinology, cardiology, psychology, pathology, and radiology. The team of doctors specialized in each of these fields contribute in a consistent manner to ensure continuity and steady growth of database. Moreover, biobank including blood, urine, stool, pathology slides (digitized by scan), and liver tissue samples, are collected and stored in the same day of biopsy.
