ABSTRACT
Objective To analyze the clinic data of peripheral CIK cell increased abnormally in adults and discuss the function of the laboratory indexes on disease diagnosis ,monitoring and therapeutic intervention .Methods The peripheral blood of patients was collected to analysis .The flow cytometry instrument was used to detect lymphocyte subgroup .every patient was conducted bio‐chemical analysis ,function of blood coagulation tests and examination of marrow cell and the patient′s medical record was analyzed retrospectively .Results The total number of leukocyte and the percentage of lymphocyte in peripheral blood of patient were in‐creased;immunophenotyping results showed that lymphocytes was mainly T lymphocyte ,T8 cell number was increased and number of T4 cell was decreased;CIK(CD3+56+ ) cells were in the majority .the number of CIK cells was decreased after treatment and ranged from 28 .6% to 59 .7% .there was no obvious anomaly in examination of marrow cell before and after treatment .TNF‐α,IgM were increased mildly ,C4 was decreased mildly ,and other indicators were no obviously abnormal .Conclusion It is the first time that cases with CIK cells idiopathic increased .The monitoring of flow T lymphocyte subgroup can provide clinical diagnosis ,effect monitoring and it is worth to promote .
