Adaptive response is a topic of general interest in medical research. Utilization of adaptive response has become a new treatment strategy for some diseases, the core of which is to stimulate the mechanisms of body internal protection, to improve the adaptive and anti-injury capability, and to maintain the homeostasis of the body. The existence of adaptive response indicates that the body internal protection can be induced and its key mechanism is the inducement of internal protective factors (internal protective proteins). In this article, some connections between adaptive response and the theory of traditional Chinese medicine (TCM) were discussed, which indicated that adaptive response is much beneficial for explaining some theories of TCM such as correspondence between human and nature, strengthening healthy qi to consolidate constitution, acupuncture theory, adaptogen herbs, and treating disease before its onset, etc. Thus the adaptive response is of great significance for explaining scientifically the connotative meaning of the theories of TCM and for promoting the integration of TCM and western medicine.

The vectors play an important role in gene therapy by transporting the therapy genes into target tumor cells. At present there are mainly two kinds of gene vectors, including biological and non-biological vectors. Biological vectors, including virus, bacteria and stem cells, have good target activity and can efficiently delivery the genes into target tumor cells, but have potential genetic hazards.However, non-biological vectors, including liposomes and nanoparticles, can be simplely prepared with high genetic safety, but they can not transport the genes efficiently. Therefore, establishing safe and effective malignant glioma gene treatment system and finding gene vectors with good target activity become the research focus.
