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).
