Surveillance for Early Liver Injuries Caused by Runzao Zhiyang Capsule.

Study Overview
=================
Brief Summary
-----------------
This is a prospective registry study to surveil early liver injuries caused by Runzao Zhiyang Capsule (RZZY Capsule) through a non-intervention observational way. And attempt to establish a predictive model to screen susceptibilities to RZZY Capsule.

Detailed Description
-----------------
The primary objectives of this study include: (i) The detection of patients with serum liver biochemistry abnormalities less than 8 weeks after intake of RZZY Capsule; (ii) The record of overall individuals with demographics, underlying diseases, physical status, medication information, clinical laboratory index, and so on; (iii) The specimen collection of surveiled individuals. (iv) The attempt to establish a predictive model to screen susceptibilities to RZZY Capsule.
