CROSS REFERENCE TO RELATED APPLICATIONS

This application is the national phase entry of International Application No. PCT/CN2017/071837, filed on Jan. 20, 2017, which is based upon and claims priority to Chinese Patent Application No. 201610061775.9, filed on Jan. 29, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a medicament for use in treating fatty liver, hepatitis and cirrhosis, which belongs to the technical field of medical technology.

BACKGROUND

Infection rate of hepatitis B virus in China is approximate 60%-70%. Hepatitis B surface antigen carrying rate takes account of 7.18% of total population, based on which it is estimated that about 93 million people carry hepatitis B virus, among of which 30 million are hepatitis B patients. Currently, patients who have jaundice hepatitis A, hepatitis disease, virus and HBE are found everywhere. There are many reason for cause or induction of jaundice hepatitis A, hepatitis B viral, such as excessive drinking, low body immunity, irregular eating. For patients with liver disease, they are discriminated to varying degrees in terms of family affection, marital love, school attendance, employment, going abroad and social intercourses. Their lives are inevitably covered with sad colors. Currently, there is no method to cure hepatitis virus, but only relieve it. Patients has to take medicines for long time which is not only troublesome, but also expensive. Furthermore, it is easy to recur.

At present, there is no specific medicine to treat chronic hepatitis B, hepatitis C and liver cirrhosis. The interferon commonly-used in present has certain effect on chronic hepatitis B, hepatitis C and liver cirrhosis. For instance, its response rate is only at 15%-20% for treatment of hepatitis C (Effect Research of Interferon on Hepatitis C: Chinese Journal of Integrated Traditional and Western Medicine on Liver Disease, volume 2002-12, 1st issue, page 56); however, big side effect, high recurrence rate and expensive price make the interferon not conforming with Chinese medical consumption level.
