Cancer of digestive system is one of the most common worldwidely cancers and seriously threats to human health. However its etiology and pathogenesis are still not clear. Toll-like receptor (TLR), a newly discovered transmembrane receptor, plays an important role in innate immunity. Recent researches suggested that TLRs had extensive relationship with inflammation, autoimmune diseases and cancer. A large number of researches indicated that TLRs not only participated in the occurrence, development and immune escape of cancer, but also acted in immunotherapy in digestive system. Further investigation of TLRs may re-veal the effects of TLRs in the development of malignant tumors of digestive system, moreover may find new therputic target for the treatment of cancers. We reviewed the relationship between TLRs and cancers of di-gestive system.

This study was aimed to establish Chinese medicine efficacy concept network in order to reveal the in-ner relation between traditional Chinese medicine (TCM) and efficacy as well as to suggest the application way of efficacy concept network. Through the collation of medicine efficacy recorded in the Pharmacopoeia of the People's Republic of China (2010 Edition, Volume I), the correlation relationship between TCM efficacy concept was systematically analyzed, and the efficacy concept network was constructed in order to extract specific effica-cy sub-network based on efficacy concept network and then to discover the efficacy groups by utilizing the net-work clustering algorithm. In the Chinese medicine efficacy concept network, 422 efficacy concepts were con-structed and 21 tightly efficacy groups were discovered. Using the efficacy of promoting blood circulation as an example, the application of sub-networks was discussed. Chinese medicine efficacy concept network can be used to reflect the basic theory and clinical experiences in Chinese medicine , to systematically reveal the relationship between TCM efficacy concepts, which can be beneficial to guide the reasonable application of Chinese medicine in disease treatment .

Functional analysis concisely summarizes and concentrates on the therapeutic characteristics and features of Chinese herbal medicine. Standardization of the terms for Chinese herbal functions not only plays a key role in modern research and development of Chinese herbal medicine, but also has far-reaching clinical applications. In this paper, a new method for standardizing the terms for Chinese herbal function was proposed. Firstly, functional targets were collected. Secondly, the pathological conditions and the mode of action of every functional target were determined by analyzing the references. Thirdly, the relationships between the pathological condition and the mode of action were determined based on Chinese medicine theory and data. This three-step approach allows for standardization of the terms for Chinese herbal functions. Promoting the standardization of Chinese medicine terms will benefit the overall clinical application of Chinese herbal medicine.
