About this trial
To study the expression level of biomarkers such as GITRL in peripheral blood of children with asthma and analyze their correlation with the severity of asthma. To study the predictive value of biomarkers level for the occurrence and development of asthma. And to provide supplementary detection means and predictive indicators for the diagnosis of asthma and the severity of asthma.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
In line with the diagnostic criteria in the Guidelines for the Diagnosis and Prevention of Bronchial Asthma in Children (2016 Edition)
Age: 4-12 years old for new diagnosis or recurrent episodes
Typical clinical manifestations and complete clinical data
Family members or guardians of children with informed research and signed consent
Disqualifiers
Suffering from other respiratory diseases (such as bronchiectasis, allergic rhinitis, respiratory failure, tuberculosis, obstructive airway disease) or other inflammatory diseases.
Abnormal development of congenital airway and lung tissue
History of immunosuppressant or glucocorticoid use in the first 4 weeks
Suffering from other endocrine system and immune system diseases
Trial population
Children with typical asthma symptoms, such as cough, wheezing, chest tightness, dyspnea and abnormal lung function tests, were diagnosed with asthma by a respiratory doctor
Trial design
Case-control
Prospective
Treatments tested in this trial
The level of biomarkers in Peripheral blood
Diagnostic testAll participants will be extracted 5ml peripheral blood into the anticoagulant tube by nurses and the peripheral blood will be detected for biomarkers of asthma. Children with asthma will take pulmonary function, blood test and specific IgE test etc. The lung function test will be performed by professional technicians and the results will be interpreted by specialists. The blood test and specific IgE test will be collected by specialist nurses and the results will be issued by professional inspectors. Children with asthma and their guardians will be asked for filling the questionnaire of Childhood Asthma Control Test (C-ACT). And then the doctor will check and calculate the scores after completion.

The correlation of pulmonary function (FEV1) and the level of biomarkers in children with asthma.The lung function test will be performed by professional technicians and the results will be interpreted by specialists.
Pulmonary function(FVC%)
The correlation of pulmonary function (FVC%) and the level of biomarkers in children with asthma.The lung function test will be performed by professional technicians and the results will be interpreted by specialists.
Pulmonary function(FEV1/FVC)
The correlation of pulmonary function (FEV1/FVC) and the level of biomarkers in children with asthma.The lung function test will be performed by professional technicians and the results will be interpreted by specialists.
Pulmonary function(PEF%)
The correlation of pulmonary function (PEF%) and the level of biomarkers in children with asthma.The lung function test will be performed by professional technicians and the results will be interpreted by specialists.
