But it also exposed that the concept and aim of IM are indistinct, and there were shortages in interpretation TCM by WM and lack of deep research in methodology. Therefore, up to now IM only localized in clinical diagnosis and treatment, but not in theory and thought. The modes of TCM and WM have aspect of difficult intergradation, and aspect of easy one that is the growth and integrated point for IM.

由毛泽东主席亲手拉开的中西医结合序幕，经过四十多年的努力，从辨证与辨病、治愈机制和理论几个不同层面分别进行了结合研究，在基础理论研究，特别是在提高临床疗效方面取得了可喜的成就，但同时也暴露出对中西医结合概念和目标认识模糊，存在着以西解中、方法论研究缺乏力度等不足，从而造成了至今中西医结合主要局限于临床诊治层面，在理论、特别是在思维方式层面上，中西医尚处于结而未合的状态。
