COVID-19 | Biological: Dental pulp mesenchymal stem cells | Early Phase 1 |
Open, single center, single arm test design. Plan to enroll 24 subjects. On the basis of clinical standard treatment, the injection of dental mesenchymal stem cells was increased on day 1, 3 and 7 of the trial.
Injection dose: 1.0x106 cells /kg. Injection method: slowly and quietly drop 50 mL of normal saline, then the endodontic mesenchymal stem cell injection (after 60 min), and then 50 mL of normal saline.

Experimental: Pulp mesenchymal stem cells
1. 3, 7 days to increase the injection of mesenchymal stem cells

Biological: Dental pulp mesenchymal stem cells
On the basis of clinical standard treatment, the injection of dental mesenchymal stem cells was increased on day 1, 3 and 7 of the trial. |
- Disppear time of ground-glass shadow in the lungs [ Time Frame: 14 days ]Kaplan-meier method was used to calculate the median glassy shadow time in all subjects
- Absorption of Lung shadow absorption by CT Scan-Chest [ Time Frame: 7, 14, 28 and 360 days ]Kaplan-meier method was used to calculate the median lung shadow absorption of all subjects on 7, 14, 28, and 360 days
- Changes of blood oxygen [ Time Frame: 3, 7 and 14 days ]T test was used to compare the blood oxygen values of each subject at day 3, 7 and 14
