In this review, the toxicity of CMM and the toxicity classification of CMM were introduced. And traditional TCM theory and methods particularly used for control and attenuation of CMM's toxicity were described in detail. The traditional processing technology and CMM drug combination were most important detoxifying measures used in CMM formulation and clinical practice. Finally, some factors that have influence on occurrence of CMM's toxicity were discussed such as different species, producing technology and so on.展开更多

Methods The equipment with cold/hot pads was used to investigate the variety of the temperature tropism between two groups of mice treated by MHD and MSD, respectively. Meanwhile, the activities of adenosine triphosphatase (ATPase), superoxide dismutase, succinate dehydrogenase, and malondialdehyde were measured. Results After treated by MHD, the macroscopic behavioral index of remaining rate on warm pad (40 ℃ ) of mice decreased significantly (P < 0.05), suggesting the enhancement of cold tropism, meanwhile, the internal indices of ATPase activity and oxygen consuming volume increased significantly (P < 0.05), suggesting the enhancement of energy metabolism. On the other hand, the above-mentioned indices in MSD group changed on the inverse way. Conclusion The relative drug nature of MHD and MSD revealed in this study is consistent with the theoretical prognostication or definition. It indicates that the internal cold and hot nature of CMM could be reflected in ethological way on the changes of animal temperature tropism which might be internally regulated by body energy metabolism.展开更多

文摘Objective:To identify the relationship between the active compounds in turmeric(Curcuma Longa L.,C.Longa)and their medicinal properties,and clarify the chemical material basis of the medicinal properties in C.Longa.Methods:High throughput screening models of the thermo-transient receptor potentials(thermo-TRPs)and human taste type 2 receptors(hTAS2Rs)were established to evaluate the activity of the active compounds in C.Longa.The biological processes and distributions of the related targets of the active compounds were acquired by data mining.The above results were then used as basic data to comprehensively analyze the material basis of the medicinal properties of turmeric.Results:Curcumin inhibited TRPV1,TRPV2,TRPV3,and TRPA1,while demethoxycurcumin(DMC)inhibited TRPV3,TRPA1,and TRPM8.In terms of the 21 hTAS2Rs,the response values of hTAS2R38,hTAS2R16,and hTAS2R44 intervened by curcumin were ranked top three;the response values of hTAS2R3,hTAS2R1,and hTAS2R9 by DMC were in top three;the response values of hTAS2R47,hTAS2R39,and hTAS2R43 by bisdemethoxycurcumin(BDMC)were in top three.The biological processes related to active compounds primarily involved blood circulation,ossification,and regulation of the inflammatory response.Conclusion:Curcumin,DMC,and BDMC were identified as the material basis of the property of Chinese materia medica of C.Longa.Among these,curcumin and DMC may contribute to its warming effect in the four qi.Curcumin,DMC,and BDMC may lead to its bitter flavor,and the three active compounds were consistent with the meridian entry of C.Longa.Although different compounds play diverse roles in the four qi,five flavors,and meridian entry,they all were relevant to the efficacy of C.Longa.It is helpful to further understand the important role of the property of Chinese materia medica for the clinical application of traditional Chinese medicine.
文摘As the practice of traditional Chinese medicine developed in the United States since the 1970s,evidence has accumulated suggesting that an undetermined number of the herbs of the Chinese Materia Medica could be produced in North America.While some attempts have been made to establish production,growers are inhibited by lack of access to capital and technical support.The evidence in support of US domestic production–including(1)historical,(2)sociological,(3)ecological,and(4)agronomic factors–is reviewed.Economic obstacles to this type of production are described,as directly experienced by the farmers,Chinese herbal medicine practitioners,and organizers involved.When analyzed in reference to current trends,however,these economic obstacles appear,at least potentially,as temporary.Because popular demand supported the rise of traditional Chinese medicine practice and the growth of organic food production,these social movements could expand and promote conditions that favor domestic production of Chinese herbs.

文摘Objective:To explore the relationship between bitter taste and bitter flavor(efficacy),their character-istics were analyzed at the target and pharmacodynamic points.Methods:Compounds with bitter receptor activity were obtained by high-throughput screening models of the human bitter taste receptors(hTAS2Rs),which were used to analyze bitter taste.The efficacy of anti-asthma medications was used as an example to research bitter flavor(efficacy).The pharmacological effects of bitter taste and bitter flavor(efficacy)were classified according to the functional modules.The coverage for the same targets or pharmacological effects in the overall protein interaction network(PIN)of bitter taste and bitter flavor(efficacy)was analyzed to reveal their relationship.The effect of the compound polydatin with anti-asthma activation on hTAS2R14 was studied to verify the reliability of the aforementioned idea.Results:A total of 121 Chinese materia medica(CMM)compounds that activate hTAS2R10,hTAS2R14,and hTAS2R49 were obtained.The analysis results indicated that 108 same targets for bitter taste and bitter flavor(efficacy)were obtained,accounting for 13.9%in the PIN of bitter taste and 72.5%in the PIN of bitter flavor(efficacy).The pharmacological effects shared by bitter taste and bitter flavor(efficacy)accounted for 79%of the PIN of bitter taste and 81%of the PIN of bitter flavor(efficacy).The activating effect of the anti-asthma compound polydatin on hTAS2R14 was dose-dependent with EC 50 of 4.3 m M.Conclusion:In this study,the relationship between bitter taste and bitter flavor(efficacy)has been demonstrated from the target and pharmacodynamic points,which are based on hTAS2Rs and anti-asthma effect.Bitter taste and bitter flavor(efficacy)exhibited a high correlation.This study provides a theoretical and scientific basis for the hypothesis that“the property theory of CMM is the clinical pharmacodynamics of CMM.”
