RESUMO
The outbreak of COVID-19 has so far inflicted millions of people all around the world and will have a long lasting effect on every aspect of everyones life. Yet there is no effective approved treatment for the disease. In an effort of utilizing human ferritin as nanoplatform for drug delivery, we engineered a fusion protein by presenting receptor-binding motif (RBM) of SARS-CoV-2 virus spike glycoprotein on the N-terminus of ferritin subunits. The designed fusion protein with a cage-like structure, similar to that of corona virus, is a potential anti-SARS-CoV-2 vaccine. We hereby show the construction, preparation, and characterization of the fusion protein RBM-HFtn. Our initial affinity study confirmed its biological activity towards ACE2 receptor which suggests its mode of action against SARS-CoV-2 could be either through vaccine therapy or blocking the cellular entry of virus as antagonist of ACE2 receptor.
RESUMO
ObjectiveAnalyze the mechanism of traditional Chinese medicine Salvia miltiorrhiza in treating coronary heart disease (CHD).MethodsThe animal experiment using actual research, namely the selection of rat isolated heart perfusion model, rat model of myocardial ischemia and ventricular tachycardia in rabbits model, then the effects of different animal groups in hemodynamics, coronary flow, serum superoxide dismutase (SOD) content, malondialdehyde (MDA) the results of the content.ResultsAfter treatment, the content of SOD was significantly increased and the content of MDA was significantly decreased in the treatment group, and the difference between the two groups was statistically significant (P<0.05).ConclusionTraditional chinese medicine Salvia miltiorrhiza has significant effect on the treatment of coronary heart disease, which is beneficial to the recovery of patients' condition, and is worthy of clinical application.
