Chronic aplastic anemia has a slow onset, with bleeding as the first and main manifestation; bleeding is mostly limited to the skin and mucous membranes, and is not serious; it can be complicated by infections, but often mainly in the respiratory tract, which can be easily controlled. If treated properly and persistently, many patients can get long-term remission or even be cured, but some patients may be delayed for many years or even have a disease duration of several decades, and a few of them have clinical manifestations of acute reoccurrence at a later stage, which is called chronic reoccurrence acute type. Western medicine treatment: immunosuppressants and androgens. Chinese medicine treatment: Chinese herbal medicine to tonify the kidney, dissolve phlegm and activate blood can improve the symptoms and prolong the time of blood transfusion. I applied the method of warming the kidney, resolving phlegm, dispersing nodules and resolving stasis to treat refractory reoccurrence, and achieved certain efficacy.
