| Popis: | Tongmai Yangxin Pill (TMYX) is a traditional Chinese medicine for the treatment of angina and arrhythmia. Although its clinical application is extensive, and the curative effect is significant, little information is available on the molecular biological basis and therapeutic mechanism of TMYX for the treatment of stable angina. In this study, we analyzed serum samples of clinical patients collected from seven different clinical units in China after oral administration of TMYX using ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS). Multiple statistical analysis including principal component analysis (PCA) and partial least square discrimination analysis (PLS-DA), were used to examine metabolite profile changes in serum samples. After TMYX treatment, 10 biomarkers were reversed to the normal conditions. The above biomarkers were mainly involved in energy metabolism, amino acid metabolism, oxidative stress and inflammation. These results suggested that TMYX exerted therapeutic effects by improving myocardial energy supply disorder and amino acid dysfunction, and attenuating oxidative stress and inflammation. The present study, as the first multicenter clinical study which reveals the molecular biological basis and therapeutic mechanism of TMYX on stable angina, can provide objective indicators for efficacy evaluation of TMYX on stable angina. And it also lays a foundation for the use of TMYX clinically. |
