The main purpose of this study was to observe the effect of amino acid formula powder on alleviating food allergies in infants; to evaluate the role of food avoidance and open-ended stimulation test in the diagnosis of food-allergic infants; to observe the allergic process in children with food allergy and to explore the criteria for diagnosis and treatment. The baby here refers to an infant between the ages of birth and 6 months of age.
This study used a multicenter, prospective cohort study. Nine research units conducted research at the same time in different locations at different locations to ensure the scientific, authenticity, objectivity and reliability of the research conclusions.
The number of design samples in this trial was 180. Considering the exit rate of no more than 10%, a total of 200 cases were completed.

|Milk Protein Allergy|
This study used multi-center, prospective cohort study. Nine research units conducted the research in different locations according to the same program at the same time to ensure the scientific, authenticity, objectivity and reliability of the research conclusion.
A total of 180 samples were designed for completion, taking into account the withdrawal rate of no more than 10%.
The inclusion criteria age: 0 ~ 6 months clinical doctors diagnosed with food protein in children with allergic (any of the skin, gastrointestinal tract or respiratory symptoms or signs) Mother feeding Life is stable Legal custodian signed informed consent Exclusion criteria all kinds of congenital, children with inherited metabolic diseases Gastrointestinal obstruction Children with immune deficiency disease The mixture of ammonia base acid is known to be allergic Researchers identify as disqualified Exit criteria Where the child/parent or guardian has the right to withdraw from the study at any time for any reason; If the disease is aggravated within 48 hours of treatment, the patient should withdraw from the trial and be treated as invalid.
Patients were asked to withdraw from the study if they were unable to continue to participate in the study, such as complications, adverse events, violations of protocol, or reasons for taking medication.
Follow-up arrangement The observation period of each child was 6 months, followed up once a month. Follow up 1 year after observation.
Validity index main outcome indicators: open food provocation tests positive incidence; secondary outcome indicators: body weight, body length, head circumference and arm muscle circumference; Improvement of food protein allergy symptoms (SCORAD, gi, respiratory, comfort scores).
Clinical trial procedure
All children should complete the following contents before entering the study:
The parent/guardian signs a written informed consent Audit inclusion/exclusion criteria Molly I have general information Physical examination, including vital signs, weight, abdominal signs, systemic conditions Routine blood test, stool test, IgE test. The researcher should inform the child and his/her parent/guardian of the date of the next visit.
If the child withdraws, the reason for withdrawal should be recorded in the case report form.
