Pneumonia is the world's leading cause of death in young children and elderly people. It is an infection that inflames the air sacs in one or both lungs, filling the air sacs with fluid and causing a cough, fever, chills, and breathing difficulties.
Traditional Chinese medicines (TCMs) are widely used throughout the world in the prevention and treatment of viral pneumonia through the belief in their potential to boost the body's resistance to the pneumonia virus and modulate its immune response. Many viruses have established sophisticated mechanisms to interact with the host immune system.
TCMs have been shown to enhance antibody production and T cell proliferation, and the expression of antigen-specific responses.[i] TCMs, composed of various kinds of medicinal plants, animals and minerals in the form of oral liquid, powder and granules, have been reported to achieve certain therapeutic effects but their mechanism remains unclear.
Metabolomics helps understand the metabolic changes of a complete system under different kinds of physiological and pathological conditions. This property of metabolomics agrees with the holistic thinking of TCMs, suggesting it has the potential to improve our understanding of the theory behind the evidence based TCM.
In recent years, an increasing number of metabolomics studies have examined the metabolic profiles after TCM treatment of viral pneumonia.[iv] Metabolomics may provide an opportunity to clarify the action mechanism of TCM and the meaning of evidence-based TCM by developing the systematic analysis of the metabolites and discovering various biomarkers and perturbed pathways after TCM treatment.
One study[v] looked at eight published metabolomics and TCM extracts related articles to find several different metabolites, including triglycerides, amino acids and carbohydrates, were perturbed in viral pneumonia groups. Metabolomics data from this research suggested that the active compound and herbs, such as Scutellaria baicalensis Georgi, Polygonum cuspidatum Sieb. Et Zucc, Flos Lonicerae Japonica and Fructus Forsythiae were effective in combating viral pneumonia. Five published metabolomics and TCM formulas-related articles were listed and 17 TCM-related plant species and four TCM formulas were found to be effective to combat viral pneumonia.
Metabolomics is a top-down strategy to reflect the function of living organisms from the end products of the metabolic network.[vi]
It is set to be a powerful approach to support TCM research in the future. Current research on TCM is still in its infancy because of the multi-component mixtures that often possess their own inherent holistic bioactivities. At Bruker, we believe that metabolomics-pharmacological research supported by our cutting-edge, integrated metabolomics solutions will see exciting developments as the ancient tradition of TCM is brought to the light of science.
