Research Strategy of Mechanism of Efficacy Enhancing and Toxicity Reducing of Antibiotics Combined with Chinese Medicine for Infectious Diseases / 中国实验方剂学杂志

ABSTRACT

The decreased efficacy and severe side effects of antibiotics, as well the increase of multidrug resistant pathogens are seriously threatening human health. It has become an urgent task for the whole world to actively respond to threats and establish effective prevention and control plans. Traditional Chinese medicine (TCM) has a long history with exact curative effect in the treatment of infectious diseases. It not only inhibits pathogens and eliminates endotoxin, but also has therapeutic effect on inflammation, immune abnormality and overall disorder caused by infection. Antibiotics mainly inhibit the pathogen itself, while the combination of TCM and antibiotics is complementary with each other and is considered as a feasible solution to the challenges. Some clinical observations have shown that TCM has potentiality of enhancing antibiotics efficiency and reducing toxicity. Exploring its mechanism is the necessary measure to optimize and popularize treatment regimen. Firstly, multi-level and multi-dimensional systematic pharmacology network analysis methods are used to predict the mechanism of TCM combined with antibiotics in the treatment of infectious diseases, so as to provide the evidence for further empirical research and selection of test indicators. Then by following the principle of corresponding drug use in specific TCM syndromes, the antibiotics and TCM are individually and jointly applied to treat patients with specific syndrome conditions of infectious diseases. Besides routine and comprehensive evaluation of synergistic and attenuated effect of the combined drug use, multi-omics technique is also used to find the subtle effects of these two drugs at a molecular level. The sensitive and stable clinical biomarkers of synergism and attenuation of combined drug use are determined by using biomolecular network analysis technology. Finally, taking these biomarkers as clues, the biotransformation process and regulation mechanism of the biomarkers are traced back in animal models of infectious diseases and cell level, and all of these are clinically verified. As a result, the mechanism of efficacy enhancing and toxicity reducing of combined drug use can be revealed, providing basis for the promotion and application of such combined drug use.
