Detailed Description
Since 2019, novel coronavirus Disease 2019 (COVID-19) has spread and prevailed all over the world. COVID-19 has a wide range of clinical manifestations of respiratory and non-respiratory symptoms, including mild or severe influenza-like syndrome, respiratory distress or respiratory failure, and may end in multiple organ failure. Mesenchymal stem cells (MSCS) are considered as ideal seed cells for the treatment of various diseases due to their unique immune regulation, self-renewal and multiple differentiation potentials. The safety of MSC transplantation in the treatment of COVID-19 patients has been proved by a number of clinical studies, and has shown good clinical efficacy in shortening the course of the disease, alleviating lung damage, and reducing the level of inflammatory factors. However, previous clinical studies mainly focused on the efficacy of MSC transplantation in critically ill patients of COVID-19, ignoring the important role of cell transplantation in delaying or preventing COVID-19 's progress and preventing reinfection.COVID-19 has spread throughout the country and even the world, and the increase in severe and critical cases has caused a great impact on national medical and health resources. Stem cell transplantation offers new treatment ideas for COVID-19 patients. Since the role of cell transplantation in delaying or preventing the progression of light and medium novel coronavirus infection and preventing reinfection has not been clearly reported, this study intends to use MSC transplantation to evaluate the role of stem cells in the occurrence and development of novel coronavirus infection, so as to provide an important reference for the prevention and treatment of COVID-19 by MSC.

Outcome Measures
Primary Outcome Measures
- Effectiveness evaluation [Within 1 year of receiving mesenchymal stem cell transplants]
The incidence and clinical status of progression to critical type after the third stem cell transplantation were evaluated
Secondary Outcome Measures
- Hospitalization time [Time period from patient admission to discharge]
The patient's hospital stay in days should be recorded.
- oxygenation index(OI) [At the time of our patient's hospitalization and 7 days after receiving the third MSC transplant.]
The oxygenation index of the patient was quantitatively measured in mmHg.
- Oxygen saturation(SaO2) [At the time of our patient's hospitalization and 7 days after receiving the third MSC transplant.]
The blood oxygen saturation of patients was monitored by oximeter.
- Chest CT [At admission, before to the stem cell transplant, and at 1 month, 6 months, and 12 months following the third MSC transplant.]
A computed tomography (CT) scan of the patient's chest was performed to evaluate the level of inflammation, the scope of the involvement, and the degree of fibrosis in the heart and lungs.
- Pulmonary function evaluation [At admission, before to the stem cell transplant, and at 1 month, 6 months, and 12 months following the third MSC transplant.]
Lung ventilation experiments were used to measure the lung volume (in ml) and airway patency (in ml) of patients in order to assess their lung function.
- Blood biochemical examination [At admission, before to the stem cell transplant, and at 1 month, 6 months, and 12 months following the third MSC transplant.]
The progression of the lesion was determined by blood chemistry tests on a patient's blood sample, which mostly included liver function: Alanine aminotransferase (U/L),Glutamic oxaloacetic transaminase (U/L), renal function:blood urea nitrogen (mmol/L) and serum creatinine (umol/L), cardiac function: creatine kinase isoenzymes(U/L) and Troponin(ng/ml), and inflammatory factors: C- reactive protein (mg/dl) and Interleukin- 6(Pg/ml) .
- Echocardiographic examination of heart function [At admission, before to the stem cell transplant, and at 1 month, 6 months, and 12 months following the third MSC transplant.]
Echocardiography was used to evaluate the patient's myocardial contractility, primarily focusing on left ventricular ejection fraction (LVEF).
- Safety assessment [Within 1 year of receiving mesenchymal stem cell transplants]
infusion and allergic reactions, life-threatening adverse events
