China Journal of Chinese Materia Medica 2015;40(6):1212-1218
In the situation of global completion, collaborative innovation is becoming increasingly important because its advantage in risk avoiding and innovation efficiency. In order to explore the model of collaborative innovation and its evolution in traditional Chinese medicine of China, the cooperation in traditional Chinese medicine patents of China from 1985 to 2013 has been analyzed by using the method of scientometrics and social network analysis. It is proved that, though the number of grated cooperative patents has increased sharply during the last thirty years, the degree of cooperation innovation in traditional Chinese medicine of China is still not high. Moreover, in spite of the individual subject' s leading role in the past domestic collaborative innovation in traditional Chinese medicine of China, the institutions have been more and more powerful and achieved great improvement. At last, core institutions, represented by universities have played an important role in the collaborative innovation of domestic institutions, because they are key links between many institutions and promote the transferring and diffusion of knowledge.

Integrating physiological parameters measurement into mobile devices is a development tendency of mobile healthcare. Measurement methods for skin moisture and body fat content are studied in this paper. Electrodes are designed for easy integration into mobile devices, and can be embedded in the cover of the mobile phone. Experiments were conducted to obtain a fast and easy measurement method. The results of evaluation show that the measurement system can achieve the same accuracy as commercial products (with correlation above 0.9 and root mean squared error below 4%) in skin moisture and body fat content measurement. Measurement of local-area body fat content showed a nearly linear positive correlation between local-area body fat content and local-area body impedance.
