24周太极拳运动对中老年人NKT细胞及其分泌细胞因子的影响

Object: This essay aims to research the regulation mechanism of that Taijiquan how to improve immunodeficiency of the middle age and the old, by observing the influence on their blood of the factor pattern of NKT cells and its Secreting cells with 24weeks Taijiquan practice. Methods: Dividing 170 healthy the middle age and the old into two group randomly:the control group and the experimental group，the later group had 24 weeks Taijiquan practice. To test the expression of the NKT cell quantity of blood by Flow cytometry, to observe the change of cell activity of NKT cells and its Secreting cells factor IFN-?、IL-4 with proliferation. Results: It has a raise of the NKT cell quantity and the activity of the experimental group significantly，and so the expression quantity of IFN-?、IL-4 did after proliferation，the original factor pattern of cell has no change. Conclusion :It may be a important path for regulation mechanism of that Taijiquan how to improve immunodeficiency that the change of NKT cell quantity and the activity cause the secretion pattern's change of IFN-γ、IL-4.
