Based on an analysis of the status of biomass energy sources worldwide including China, this paper concludes that the development of the biomass energy industry in China is limited by factors asfollows:food security; lack of understanding of domestic sources; the deficiency of the policy environment; and environmental protection. There are also other challenges such as: low overall level of industry development; not having yet established a complete biomass energy industry system; high production costs; weak market competition; lack of investment in research and technology; low level of market admittance threshold; and disorder of industry development. Therefore, proposed policies aimed at promoting the healthy and rapid development of the biomass energy industry are as follows: improving the policy and regulatory system to enable the biomass energy industry to develop; greater evaluation of biomass energy material resources; accelerating the development of biomass energy conversion and use technologies; establishing the demonstration bases of biomass energy industry. 展开更多

OBJECTIVE: To explore the role of Traditional Chinese Medicine(TCM) in the prevention and treatment of colorectal cancer and identify possible therapeutic targets of TCM to provide clues for the use of TCM for colorectal cancer prevention and treatment in the clinic and to find novel directions for new drug discovery for colorectal cancer.METHODS: We used Pub Med and Google to search for and collect scientific publications for a full evaluation of current evidence in the literature indicating the potential role of Chinese herbal medicines and their respective ingredients as effective candidatesforcolorectalcancerpreventionandtreatment.RESULTS: We extracted a detailed description of potential therapeutic Chinese herbal medicines and their constituent ingredients that target different mechanisms in colorectal cancer such as gene mutation, dysregulation of signaling pathways, metabolism disorders, and the inflammatory microenvironment, including both conventional and non-conventional approaches.CONCLUSION: TCM may be a promising complementary and alternative therapy for the treatment of colorectal cancer. 展开更多
