Summary:
Main objective: To explore the safety and tolerability of human umbilical cord mesenchymal stem cell injection in the treatment of interstitial lung disease (ILD); Secondary objective: To explore the preliminary effectiveness of human umbilical cord mesenchymal stem cell therapy for interstitial lung disease (ILD) and recommend appropriate cell therapy doses for subsequent clinical studies; Exploring the immunogenicity of human umbilical cord mesenchymal stem cell injection in the treatment of interstitial lung disease (ILD).

Primary Outcome Measures: Maximum tolerated dose per dose (MTD), The maximum tolerable dose (MTD) of a single administration depends on whether dose limiting toxicity (DLT) occurs within 4 weeks after the first administration, for example (1) Hematological toxicity of grade 3 and above caused by the treatment of human umbilical cord mesenchymal stem cell injection. There are grade 3 and above non hematological toxic reactions caused by the treatment of human umbilical cord mesenchymal stem cell injection, except for the following cases, (3) Any other toxicity related to cell therapy that is higher than the baseline level is judged as clinically significant and / or unacceptable by the investigator and the sponsor, (4) There are acute exacerbations and serious adverse events (SAE) of IPF related to the treatment of human umbilical cord mesenchymal stem cell injection (which may be related, likely to be related and definitely related), From the first administration to 4 weeks after administration
Secondary Outcome Measures: Preliminary efficacy evaluation：lung function, Changes from baseline in lung function (forced vital capacity, diffusion capacity for carbon monoxide) in the treatment of Interstitial lung disease(ILD), and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

To study the value of dyspnea score(modified Medical Research Council, mMRC) in evaluating the life quality of patients with ILD, and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

Dyspnea score(mMRC)：Range 0-4,mMRC levels 0-1 indicate few symptoms, mMRC levels 2-3 indicate multiple symptoms, and level 4 indicates difficulty breathing at the slightest level of activity., The 4th, 12th, 24th week after administration|Preliminary efficacy evaluation: cough score, Changes from baseline in value of cough score. To study the value of cough score(Cough Evaluation Test, CET) in evaluating the life quality of patients with ILD, and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

Cough score(Cough Evaluation Test, CET)：Range 5-25, the higher the score, the more severe the daytime cough, the greater the impact of nighttime cough on sleep, and the greater the impact of cough on daily life and psychology., The 4th, 12th, 24th week after administration|Preliminary efficacy evaluation: 6-minute walk test, Changes from baseline in result of 6-minute walk test (grade and distance) in the treatment of Interstitial lung disease(ILD), and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

Draw a straight distance of 30.5 meters (100 feet) on a flat surface, and place a chair at each end as a marker. The subjects walked back and forth between them, with the pace determined by their own physical abilities. The personnel monitoring on the side report the time every 2 minutes and record any discomfort such as shortness of breath or chest pain that the subject may experience., The 4th, 12th, 24th week after administration|Preliminary efficacy evaluation: Frequency of acute exacerbation events, Changes from baseline in Frequency of acute exacerbation events in the treatment of Interstitial lung disease(ILD), and to recommend the appropriate dose of cell therapy for subsequent clinical studies, The 4th, 12th, 24th week after administration|Preliminary efficacy evaluation: High Resolution Computed Tomography scores(HRCT score), Changes from baseline in chest High Resolution Computed Tomography scores(Warrick score) in the treatment of Interstitial lung disease(ILD), and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

HRCT score(Warrick score): Range 0-30,the higher the score, the more severe the lesion type and the wider the lesion range., The 4th, 12th, 24th week after administration|Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]：Blood pressure, Blood pressure in millimeter of mercury(mmHg), The 4th, 12th, 24th week after administration|Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]：Pulse, Pulse in beats per minute, The 4th, 12th, 24th week after administration|Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]：respiration rate, Respiration rate in times/minute, The 4th, 12th, 24th week after administration|Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]：body temperature, Body temperature in centigrade(℃), The 4th, 12th, 24th week after administration|Blood routine, White blood cell count (WBC) in 10\^9/L; Neutrophil count (Neu) in 10\^9/L; Lymphocyte count (Lym) in 10\^9/L; Monocyte count (Mon) in 10\^9/L; Eosinophil count (Eos) in 10\^9/L; Basophil count(Bas) in 10\^9/L; Red blood cell count (RBC) in 10\^9/L; Platelets(PLT) in 10\^9/L; Hemoglobin (HGB) in g/L; Mean corpuscular hemoglobin concentration (MCHC) in g/L; Hematocrit (HCT) in percentage(%); Mean corpuscular volume (MCV) in femtoliter(fL)., The 4th, 12th, 24th week after administration|Blood biochemistry, Total protein (TP) in g/L; Albumin (ALB) in g/L; Total bilirubin (TBIL) in umol/L, Direct bilirubin (DBIL) in umol/L, Total bile acid (TBA) in umol/L, Creatinine (Cr) in umol/L, Uric acid (UriC) in umol/L; Alanine aminotransferase (ALT) in U/L Aspartate aminotransferase (AST) in U/L; Alkaline phosphatase (ALP) in U/L; Gamma glutamyl transpeptidase (GGT) in U/L; Lactate dehydrogenase (LDH) in U/L; Fasting blood glucose (Glu) in mmol/L; Potassium ions (K+) in mmol/L; Sodium ions (Na+) in mmol/L; Chloride ions (Cl -) in mmol/L; Calcium ions (Ca2+) in mmol/L; Glycated hemoglobin (HbA1c) in percentage(%);, The 4th, 12th, 24th week after administration|Blood gas analysis, PH; Arterial partial pressure of oxygen (PaO2) in mmHg Arterial partial pressure of carbon dioxide (PaCO2) in mmHg, The 4th, 12th, 24th week after administration|Concentration of Lung tumor markers, Cytokeratin 19 fragment (CYFRA21-1) in ng/mL; Neuron specific enolase (NSE) in ng/mL; Squamous cell carcinoma antigen (SCC) in ng/mL; Carcinoembryonic antigen (CEA) in ng/mL; Carbohydrate antigen(CA125) in Unit/mL., The 4th, 12th, 24th week after administration|Electrocardiogram, Heart rate in beats/minute; PR interval in millisecond(ms) QRS interval in millisecond(ms) QT interval (uncorrected) in millisecond(ms), The 4th, 12th, 24th week after administration
