Chinese Academy of Sciences (CAS) and China's C9 League (C9) are two of the most important research institutes in China's national innovation system. They have played vital roles in promoting the rapid
development of China's scientific research. Based on the databases of Thomson Reuters's, such as SCI/SCI, ESI, JCR, and etc., this paper carried out a comprehensive comparative analysis between CAS and C9 on their scientific research influences using bibliometrics methods. The results show that, CAS and C9's whole scientific research influences are very close. But in different fields, they often vary greatly, and each has his merits.

Heavy-ion cancer therapy is one of the most effective, cutting-edge, and successful cancer treatment technology in the world. Primary countries such as USA, Germany, Japan, and China have deployed actively in technology research and development. Based on the patents data from the Derwent Innovation Index, the state of the arts of heavy-ion cancer therapy has been obtained by using the statistical tools of the TDA and Excel. By analyzing the population distributions of the patents as a function of a parameter of International Patent Classification (IPC) such as time, patentee, and technical field, the technology development trend in the heavy-ion cancer therapy has been identified. The results provide a reference for the industry development scheme in this field.
