摘要

目的造血干细胞（HSC）移植是治疗某些血液恶性肿瘤患者的方法之一。粒细胞集落刺激因子（G-CSF）是最常用的动员 CD34+ 细胞的药物，但其数量通常较少。最近的证据显示，运动可引起造血干细胞的短暂动员。然而，运动的类型和强度尚未完全揭示。我们的目的是检测以个性化跑步速度跑步60分钟后干细胞水平的显著增加。材料/方法18名跑步者（48.2±1.9岁，峰值耗氧量为46.2±1.4毫升/千克/分钟）参加了研究。进行心肺运动测试以确定个人的跑步速度，参与者在跑步机上以接近其通气阈值（VT）的强度跑步 60 分钟。结果跑步前，CD34+造血干细胞数量为 13.9 ± 2.3 cells/μl，跑步后立即显著增加至 19.5 ± 3.6 cells/μl（p <0.05）。在第1、4和24小时，连续的造血干细胞计数分别为15.3±2.2、19.5±4.8和15.1±3.4个细胞/μl。跑步前的高 CD34+ 造血干细胞水平可能反映了对常规运动的适应性反应，而接近 VT 的 60 分钟跑步则进一步提高了造血干细胞水平。个性化的运动可能是动员外周血中CD34+造血干细胞的重要工具。

Changes in hematopoietic stem cell numbers following acute exercise in non-athlete marathon runners

Purpose

Hematopoietic stem cell (HSC) transplant is one of the curative methods for some patients with hematological malignancies. Granulocyte colony-stimulating factor (G-CSF) is the most common drug used to mobilize CD34⁺ cells, generally found in small numbers. Recent evidence showed that exercise causes transient mobilization in HSC. However, the type and intensity of exercise have not been fully revealed. We aimed to detect a significant increase in stem cell levels following 60 min of running at a personalized running pace.

Materials/methods

Eighteen runners, 48.2 ± 1.9 years with peak oxygen consumption of 46.2 ± 1.4 ml/kg/min, were enrolled in the study. The cardiopulmonary exercise test was performed to determine the individual running pace, and the participants ran 60-min on a treadmill at an intensity close to their ventilatory threshold (VT). The blood sampling for HSC count was performed before, immediately after, at the 1st, 4th and 24th hour after the 60-min running.

Results

The CD34⁺ HSCs were 13.9 ± 2.3 cells/μl before and significantly increased immediately after to 19.5 ± 3.6 cells/μl (p < 0.05). The consecutive HSC counts were 15.3 ± 2.2, 19.5 ± 4.8 and 15.1 ± 3.4 cells/μl at the 1st, 4th, and 24th hour, respectively.

Conclusion

The individual data showed that some runners had higher HSC levels than the transplantation limit before and after the 60-min running trail, which was maintained for 24 h. Pre-running high CD34⁺ HSCs may reflect an adaptive response to regular exercise, with a 60-min run near the VT further elevating HSCs. Individualized exercise may be a valuable tool to mobilize the CD34⁺ HSCs in peripheral blood for donors.
