With the development of science, the methods and the views or scientitic researcn changed from analyses to syntheses. Recently, more attention has been paid to bio-diversity and complexity. According to the study on M-CSF and its receptor for years, the author suggests that, the multi-level of bio-diversity also appears at the bio-macromolecular level. Probability of bio-diversity is one of the bases for bio-complexity. Cellular sociology and topobiology are important aspects in bio-complexity, and should be developed. If taking Chinese traditional medicine together with the advantage from Reductionism, joining the study on complexity, Chinese scientist would make a chair in the international scientific society.

According to the study on M-CSF and its receptor for years, the author Cellular that is biologically important and that it should be biologically complicated. Developed.
