But for patients with severe systemic disease with AUB, it may get worse with the conventional treatment. Novasure provides us with an effective measure for the treatment of AUB with active systemic lupus erythematosus（SLE）.展开更多

In treating it, Chinese medicine treatment combines the patients personal constitution and treatment based on syndrome differentiation; Western medicine treatment mainly applies Aspirin, active immune lymphocyte treatment, low molecular heparin, gamma globulin protein passive immune treatment and psychological intervention therapy. In this paper, a review of the treatment methods for closed antibodies in the past 5 years is made.展开更多
