ABSTRACT
OBJECTIVE: To investigate the antitumor effects of bornyl acetate (BA) isolated from Sharen (Fructus Amomi) in colorectal cancer (CRC) and the underlying mechanisms. METHODS: SW480 and HT29 cells were treated with increasing doses of BA in order to determine its antitumor effects in vitro. Cell viability, colony formation, cell cycle, and apoptosis as well as migration and invasion were assessed using various assays. In addition, the in vivo antitumor effects of BA were assessed using a xenograft mouse model. We then assessed the mechanism of action of BA by conducting pathway activator-mediated rescue experiments and assessed the protein levels by Western blot analysis. RESULTS: BA showed anti-CRC tumor activities in vitro by suppressing cell proliferation and colony formation, inducing apoptosis, blocking cell cycle, and inhibiting migration and invasion. These effects were mediated via suppression of the phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) pathway. In the tumor xenograft experiment, BA was found to repress tumor growth in vivo with low toxicity. CONCLUSIONS: The results demonstrated that BA exerts antitumor effects by suppressing the PI3K/AKT pathway, with low toxicity. Thus, BA might be a potential novel therapeutic agent for CRC.

Metal or semi-metal elements have numerous physiological and biochemical properties and have correlations with the process of occurrence and development of Zheng and Chinese herbal medicine pharmacodynamics mechanism. This article will expound the current situation of traditional Chinese medicine (TCM) research based on metal elements from the researches of Zheng, medicine theory, pharmacodynamic mechanism, prescription principles, medicine concocted theory and medicine quality control in TCM. In addition to putting forward the shortages of current researches, we also introduce metallomics, the member of Omics in systems biology to offer a new idea for modernization of TCM based on metal elements.
ABSTRACT
The characteristics and advantages of traditional Chinese medicine ( TCM ) diagnosis and treatment of chronic liver diseases are conducted on the individualized treatment based on TCM syndrome classification . In this study , the analysis of systems biology was carried out for TCM syndrome classification in chronic hepatitis B and posthepatitic cirrhosis . The relationship between TCM syndrome classification and genetic polymorphism , the difference of genes and protein expression profiles , the difference of urine metabolite , and the molecular mechanism of Different TCM Syndrome for Same Disease and Same TCM Syndrome for Different Diseaseswere discussed . The results showed that there are molecular biological basis in TCM syndrome classification in hepatitis B and posthepatitic cirrhosis . The systems biology based syndrome identification methods may be bene-ficial to form a new classification , and provide reference for the diagnosis and individual therapy of hepatitis B and posthepatitic cirrhosis .
ABSTRACT
As an important clinical mode, the disease-syndrome-efficacy integration is a development trend of traditional Chinese medicine (TCM) and western medicine combination. The mode combined comprehensive effica-cy evaluation based on disease-syndrome integration is able to highlight advantages of TCM clinical diagnosis and treatment. With the status of disease-syndrome and effects of Chinese herbal medicine treatments, the en-dogenous metabolites and metabolic network of body changed in the systemic level. According to the analysis of these metabolic changes by metabolomic technologies, it is helpful to investigate the essence of disease-syndrome and explain the mechanism of Chinese herbal medicine actions. This review summarized the current applications of metabolomics in the area of disease-syndrome-efficacy integration research . Metabolomics applied in the disease-syndrome-efficacy integration research is helpful to facilitate the development of TCM and western medicine combination .
