Surveillance for Early Liver Injuries Caused by Runzao Zhiyang Capsule.

A Registry Study to Surveil Early Liver Injuries Caused by Runzao Zhiyang Capsule (RZZY Capsule).

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.

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.

Inclusion Criteria:

1. Individuals in accordance with indications for RZZY Capsule, including skin pruritus, acne vulgaris and constipation;

2. The age range of 18 to 70 years；

3. Individuals taking RZZY Capsule over 2 weeks;

4. Abnormalities of serum biochemistry achieving one of the criteria as follows:

5. Individuals can provide informed consent form.

Exclusion Criteria:
