Abstract： By analyzing the pathological mechanism of western medicine and the etiology and pathogenesis of Chinese medicine of organ transplantation and immunologic recurrent miscarriage， it is believed that there are many similarities. In Chinese medicine，both of them take kidney deficiency as the root cause， complicated with spleen deficiency， and take blood stasis and phlegm turbidity as the symptoms， thus forming the syndrome of deficiency in the origin and excess in the superficiality. They share the same theoretical basis of the same treatment for different diseases，so their treatment methods can be learned from each other， mainly including kidney- tonifying and abortion- preventing method， spleen-fortifying and dampness-dispelling method，and blood-activating and stasis-resolving method. In terms of medication， medicines with immunomodulatory effects proven by modern pharmacological studies can be selected for application，such as Cordyceps，Salviae Miltiorrhizae Radix et Rhizoma，Corni Fructus， Tripterygii Wilfordii Radix， etc. At the same time， in addition to the “same syndrome”， “differences between diseases” should also be paid attention to. According to their disease characteristics and clinical manifestations，it is appropriate to distinguish their treatment and medication. Especially for the particularity of medication use in pregnancy，the safety of some medicines should be considered.
