[Reference values of blood lymphocyte immunophenotype in the normal healthy adults of Ugyur and Han nationalities in Xinjiang].
This study was aimed to establish the reference values of blood lymphocyte immunophenotype in healthy adult between Ugyur and Han nationalities in Xinjiang and to compare the difference between these two nationalities in respect to nationality and gender, anticoagulated peripheral blood samples of 75 Ugyur people and 104 Han people were stained with monoclonal antibodies; the lymphocytes were analyzed by flow cytometry for the expression of lymphocyte-population bearing surface markers, the data were analyzed by SPSS 11.0. The results showed that the reference ranges of blood lymphocyte subsets in Uygur and Han adults were as follows: total T cells amounted to 67.85 +/- 8.97% and 69.98 +/- 10.14% respectively; helper T cell to 36.86 +/- 5.74% and 40.07 +/- 6.10% respectively; inhibitor T cell to 26.67 +/- 6.15% and 27.16 +/- 6.29% respectively; CD4/CD8 ratio to 1.46 +/- 0.47 and 1.56 +/- 0.47 respectively; NK cell to 16.91 +/- 9.89% and 12.81 +/- 7.34% respectively; B cell to 10.09 +/- 3.33% and 11.78 +/- 3.81% respectively; CD3(+)/HLA-DR(+) to 10.05 +/- 2.95% and 11.27 +/- 4.98% respectively; CD25(+) cell to 1.76 +/- 5.26% and 4.10 +/- 4.30% respectively. The differences of those two nationalities were mainly in total T cells, NK cell, B cell and CD25(+) cell. Furthermore there were also some differences between male and female. There might exist differences in helper T cells, CD4/CD8 ratio between Ugyur male and female, while this difference in Han lied in inhibitor cell and NK cell. Compared to those of two nationalities, the helper T cell percentage and CD4/CD8 ratio of Uygur male were lower than those in Han male. And in female, Uygur people had higher percent of NK cell (P < 0.01), but lower CD25(+) cell than those in Han's (P < 0.01). In conclusion, the nationalities and gender could influence the reference value of lymphocyte immunophenotype, the reference values of blood lymphocyte immunophenotype in the normal healthy adults of Ugyur and Han nationalities in Xinjiang were defined, and the differences between these two nationalities in respect to nationality and gender were elucidated.
