Professor HUANG Shilin thinks that the occurrence of aplastic anemia is closely related to deficiency of the kidney. According to syndrome differentiation

this disease can be divided into deficiency of kidney Yin

deficiency of kidney Yang

and deficiency of kidney Yin and Yang. On the basis of state and course of the disease

aplastic anemia can be divided into progressive stage

stable stage and remittent stage. He emphasizs that syndrome differentiation should be combined with staging in the treatment of aplastic anemia.
