Abstract:
Objective To detect the alteration of circulating CD34 + cell level in patients with the In'st-ever nonlacunar stroke and to investigate the prognostic value of CD34 +cell level. Methods 1he level of the circulating CD34+ cells were examined using flow eytometry in 119 patients with nonlacunar infarction. 1he patients were divided into group A (higher than average) and group B (lower than average) according to the detected values, The National Institutes of Health Stroke Scale (NIHSS) scores on admission and the modified Rankin Scale (mRS) scores at 3 months after the onset in the two groups wre compared. Results The level of CD34 + cells in group A was significantly higher than that in group B (0. 048 ± 0. 001 versus 0. 032 ± 0. 002, P < 0. 05 ), however, there was no significantly difference in NIHSS sores between the two groups. One week after admission, the increased level of CD34 + cells in group A was significantly higher than that in group B (0. 001 ±0. 003 versus - 0. 005 ± 0. 000, P < 0. 05 ). Three months after the onset of symptoms, the average mRS score in group A was significantly superior to that in group B (2. 98 ± 1.14 versus 3.25 ± 1.39, P <0. 05). 1he level of circulating CD34 + cells at the initial onset of symptom was negatively correlated with the mRS score at 3 months after stroke (r = -0. 48, P <0. 05). Conclusions The higher level of circulating CD34+ cells had better prognosis in patients with cerebral infarction. The level of circulating CD34+ ceils may be used as a prognostic indicator in patients with cerebral infarction.
