The investigation is a randomized, double-blind, placebo involved and multi-center clinical trial. All subjects are assigned to 2 groups, including Oryz-Aspergillus Enzyme and Pancreatin tablet group (treatment group) and the placebo group (control group). Treatment group includes 99 subjects, while control group includes 33 subjects. They receive investigational drug 2 tablets/times, tid, p.o. for 180 days.

• A total of 132 subjects with cirrhosis were divided into 3 subgroups by Child-Pugh score, which were Child-pugh Class A, B, and C, respectively. Each subgroup includes 44 subjects, which were randomly assigned to the Oryz-Aspergillus Enzyme and Pancreatin tablet group (treatment group) and the placebo group (control group) in a ratio of 3: 1 (33: 11).
• Patients who have signed the Informed Consent Form and are eligible for the entry criteria will be randomly assigned to either the Oryz-Aspergillus Enzyme and Pancreatin tablet group or the placebo group. No matter which group the subjects is assigned, he/she would receive treatment drugs through oral administration for 180 days, during which the participant will not take any investigational drug.
• The differences in nutritional status between treatment group and control group will be compared in 90 and 180 days by MAMC and SGA.

Inclusion Criteria:

• The age is range from 18 to 70 years old.
• Sex is not limited.
• Confirmed cirrhosis (pathologic or radiological rationale) with a mid-upper arm muscle circumference (MAMC) < 90% of the standard value.
• The subject or his family (guardians) agreed to participate in the study and signed the informed consent form.

Note: MAMC formula: mid-arm muscle circumference (cm) = mid-arm circumference (cm) - 3.14 × triceps skinfoldthickness. Standard values: 25.3 cm for adult males and 23.2 cm for adult females.
