Clinical Trial Summary

In this study, the investigators will include PCOS patients and healthy women who meet the trial criteria from the clinical research centers of 3 hospitals, introduce the content of this study to participants, and invite participants to participate. Flow cytometry was used to detect the immune function of peripheral blood samples of PCOS patients, to clarify the immune function characteristics of PCOS patients, and to try to establish an evaluation method of the immune function of PCOS patients.

Description:

PCOS patients and healthy women were recruited in outpatient clinics of three hospitals, and peripheral blood was retained for flow cytometry after completing relevant examinations. In this study, flow cytometry was used to detect the antigenic antibody reaction between the surface differentiation antigen of lymphocyte membrane and fluorescence-labeled antibody in human peripheral blood, and the unlabeled cells were dissolved. The number and percentage of cell groups expressing different markers were counted by the fluorescence detection system on flow cytometry.
