ABSTRACT
Objective To investigate the changes and significances of peripheral blood CD34,KDR/CD34,CD133/CD34,and CD117/CD34 positive cell levels in patients with hemorrhagic stroke at the acute phase. Methods Thirty patients with acute hemorrhagic stroke admitted to the Department of Neurosurgery, Jiangsu Haimen People’s Hospital from September 2013 to April 2014 were enrolled retrospectively. At the same time,20 healthy subjects were selected as a control group. CD34 +,KDR+ /CD34 +,CD133 + /CD34 +, and CD117 + /CD34 +cell levels in peripheral blood were detected in patients with hemorrhagic stroke at day 1 to day 7 after cerebral hemorrhage and the day of physical examination of the control group using FACSCalibur flow cytometry. The data were obtained and analyzed using CELLQuest software. Results Peripheral blood CD34 + cells and KDR+ /CD34 +, CD133 + /CD34 +, CD117 + /CD34 + cells at day 1 to day 7 after ischemic stroke were all lower than control group (all P<0. 05). CD34 + and CD117 + /CD34 + cells decreased firstly at day 1 and 2, then increased gradually;KDR+ /CD34 + and CD133 + /CD34 + cells increased gradually at day 1 to day 5,they were all reached the peak at day 5,which were (14. 8±3. 5) í105 and (16. 7±3. 3) í105 respectively. Compared with that at day 1,CD34 + cells at day 5 and 6 were (27. 4 ±6. 3) í105 and (25. 4 ±5. 7) í105 respectively;KDR+ /CD34 + and CD133 + /CD34 + cells at day 4,5,and 6 were (10. 2±3. 1) í105,(14. 8±3. 5) í105,(12. 1±3. 4) í105 and (14. 3±3. 6) í105,(16. 7±3. 3) í105,and (13. 1±4. 0) í105,respectively;CD117 + /CD34 + cells at day 5 was (21. 3 ±4. 2) í105,which were all higher than the first day after cerebral hemorrhage (P<0.05). In the CD34 + cells,the proportion of KDR+ /CD34 + cells at day 1 to day 7 all decreased compared with the control group (all P<0. 05);the proportion of CD133 + /CD34 + cells at day 4 was (65±4)%,it was higher than the control group (P<0. 05);the proportion of KDR+ /CD34 + cells at day 5 was (55±6)% compared with day 1;the proportion of CD133 + /CD34 + at day 4 was (65 ±4)%;the proportions of CD117 + /CD34 + cells at day 4 and day 5 were (69 ±6)% and (72 ±6)% respectively,and they all increased (all P <0. 05). Conclusion Peripheral blood CD34 + cells and their cell subsets are change in patients with hemorrhagic stroke in acute phase. Speculating the different cell subsets may have different functions and potential. KDR+ /CD34 + and CD133 + /CD34 + may be the early sensitive indicators of acute hemorrhagic stroke,and CD117 + /CD34 + is largely mobilized in early stage.
