目的：现察介入放射诊疗人员防护前后的 Ｔ细胞亚群、ＩＬ－２Ｒ（ＣＤ２５）、ＮＫ细胞（ＣＤ１６）的影响．方法：左３２名放射科人员中选择从事介入放射诊疗１０年以上，慢性疲劳症状突出者１０人为现察对象；使用功能性食品抗疲Ｉ号胶囊防护，设防护前组（ＢＧ）、防护后组 （ＡＧ）、对照组（ＣＧ），使用流式细胞仪测定防护前后的 Ｔ细胞亚群、ＣＤ２５、ＣＤ１６。结果：ＡＧ与ＢＧ相比，总Ｔ细胞ＣＤ３上升，亚群中的ＣＤ８呈上升，ＣＤ４略有下降，ＣＤ４／ＣＤ８下降，ＣＤ２５和ＣＤ１６上升（Ｐ＜０.０５，Ｐ＜０．０１）；ＢＧ与ＣＧ相比，ＣＤ３、ＣＤ４、ＣＤ８、ＣＤ１６、ＣＤ２５均呈低下水平（Ｐ＜０.０５，Ｐ＜０.０１），ＣＤ４／ＣＤ８。比值出现异常升高等．结论：长期从事医疗辐射环境在危害机体造血的同时，也危害Ｔ细胞亚群及 Ｔ细胞 ＣＤ１６、ＣＤ２５的表达，Ｉ胶囊有明显的改善造血、调节细胞免疫功能的抗辐射作用．
Objective: To investigate the influence of T cell subsets, IL-2R (CD25) and NK cells (CD16) before and after interventional radiologists treatment. Methods: The left 32 radiologists were involved in the interventional radiology for more than 10 years, and 10 persons with chronic fatigue symptoms were investigated. The functional food anti-fatigue I capsule protection, pre-protection group (BG) Group (AG) and control group (CG). T cell subsets, CD25 and CD16 before and after protection were measured by flow cytometry. Results: Compared with BG, total CD3 of total T cells increased, CD8 in subgroup increased, CD4 decreased slightly, CD4 / CD8 decreased, CD25 and CD16 increased (P <0.05, P <0.01); Compared with CG, BG, CD3, CD4, CD8, CD16 and CD25 all showed low level (P <0.05, P <0.01) and CD4 / CD8. Ratio abnormal increase. Conclusion: The long-term medical radiation environment, while endangering the hematopoiesis of the body, also endanger the expression of CD16 and CD25 on T cell subsets and T cells. I capsule has a significant effect on hematopoiesis and anti-radiation effects of cellular immune function.
