Changes of serum MMP3 concentration in novel coronavirus patients during hospitalization
In order to detect serum MMP3 concentrations, sera from 20 patients were collected thrice approximately every 5 days according to the duration of hospitalization. All were cured and discharged from hospital. Medians and interquartile ranges were used to describe these 3 serum MMP3 levels, the first time point being 55.98(30.80~75.97) ng/ml, the second 34.84(0.00~51.84) ng/ml and the third 5.71(0.00~40.46) ng/ml. The 3 serum MMP3 concentration levels showed a decreasing trend. The distribution of MMP-3 serum concentrations over the 3 detection times is shown (Fig. 2).
