  • Patent number: 10639289
    Abstract: The present invention discloses an application of neuraminidase and inhibitors thereof in myocardial ischemia and myocardial infarction, provides a correlation between neuraminidase and myocardial ischemic damage to prove the myocardial ischemic damage can be alleviated by inhibiting the activity of neuraminidase, and to prove the neuraminidase can be used as a target for screening drugs for preventing, alleviating and/or treating myocardial ischemic damage. The present invention also demonstrates the alleviating effect of neuraminidase inhibitors on myocardial ischemic damage. Neuraminidase inhibitors improves myocardial ischemic damage by reducing the level of neuraminidase. The present invention further provides a pharmaceutical preparation comprising neuraminidase inhibitor(s) and pharmaceutically acceptable carrier(s), the pharmaceutical preparation can be used for reducing the level of neuraminidase, thus improving myocardial ischemic damage.

  • Patent number: 10502748
    Abstract: This application discloses a method of differentiating stable angina pectoris from acute coronary syndrome, including: obtaining a blood plasma sample from a patient; measuring a relative concentration of at least one metabolic biomarker in the blood plasma sample, wherein the at least one metabolic biomarker is selected from the group consisting of malic acid, taurine, arachidonic acid, citramalic acid, methionine, and pentadecanoic acid; calculating a value according to the relative concentration of at least one metabolic biomarker; comparing the value with a predefined critical value, if the value is more than the predefined critical value, the patient has the acute coronary syndrome, otherwise, the patient has the stable angina pectoris. The method and a diagnostic kit thereof is capable of differential diagnosis of SA and ACS and it can improve the diagnostic convenience and promote the diagnostic standardization.

  • Publication number: 20170276653
    Abstract: A panel of metabolic biomarkers for differential diagnosis of stable angina pectoris and acute coronary syndrome is published herein. The panel comprises one or more of the metabolic biomarkers, including malic acid, taurine, arachidonic acid, citramalic acid, methionine, pentadecanoic acid. Single use of the 6 differential metabolites provided clinically diagnostic value of SA vs. ACS with AUC>0.7. When combined, the more metabolites, the larger of AUC. The highest AUC of 0.987 was obtained when all of the six metabolites were combined to distinguish SA vs. ACS with sensitivity 96.8% and specificity 97.7% using optimal cut-off value. The metabolic biomarkers provided by the invention can be used for differential diagnosis of SA vs. ACS of high accuracy, sensitivity and specificity.
