Objective To sum up main syndrome differentiation points of liver depression and spleen asthenia syndrome of chronic hepatitis B （CHB）. Methods Logistic regression and discriminant analysis were used for analysis of symptoms, tongue and pulse of liver depression and spleen asthenia syndrome, liver depression syndrome and spleen asthenia syndrome.
