摘 要:目的观察粒细胞集落刺激因子(G-CSF)对外周血细胞及炎性因子的影响。方法38只清洁级大白兔随机分两组制备心肌梗死模型,梗后第2天,G-CSF组给予G-CSF10μg/(kg·d),对照组生理盐水0.5mL/(kg·d),皮下注射共5d,廊液自动分析仪检测外周血细胞,酶联免疫吸附试验(ELISA)检测超敏C反应蛋白(HsCRP)、肿瘤坏死因子-α(TNF-α)水平。结果梗后7、14d白细胞总数(WBC),中性粒细胞(N)数G-CSF组高于对照组(P〈0.05)。HsCRP梗后7d,G-CSF组高于对照组(P〉0.05);梗后14dG-CSF组[(2.02±1.57)mgCL]低于对照组[(4.12±0.68)mg/L(P〈0.05]。TNF-α在梗后7dG-CSF组高于对照组(P〉0.05),梗后14dG-CSF组[(40.9±17.7)ng/L低于对照组(53.2±14.8)ng/L,P〈0.05]。结论G-CSF有助于WBC总数的升高,并对急性期炎性细胞因子的升高有轻度影响,但可促进炎性细胞因子的尽早恢复。Objective To find out the changes in blood cell counts and inflammatory cytokines after granulocyte colony stimulating factor (G-CSF) traetment in rats with myocardial infarction. Methods Thirty-eight healthy New Zealand white rabbits were divided into two groups: 10μg/(kg·day) G-CSF in G-CSF group and O. 5 ml/( kg· d) saline in control group starting at 24th h after infarction, once daily for 5 days. Results White blood cells (WBC) and granulocytes (N) were significantly increased in G-CSF group as compared with those in control group ( P 〈 0. 05 ) at 7th and 14th day after myocardial infarction. High sensitivity C reactive protein (HsCRP) levels in G-CSF and control group were (7. 32 ±2. 32) mg/L and (6.53 ±1.21) mg/L at7th day (P〉0.05), and (2.02 ±1.57) mg/L and (4. 12 ±0.68) mg/L at 14th day after myocardial infarction ( P 〈 0. 05 ) , respectively. TNF-α levels in G-CSF and eontrol groups were ( 80. 1 ± 40. 1 ) ng/L and (74.4 ± 39. 1 ) ng/L at 7th day ( P 〉 0. 05 ), and (40.9 ± 17.7 ) ng/L and (53.2 ± 14.8 ) ng/L at 14th day after myocardial infarction ( P 〈 0. 05 ), respeetively. Conclusion G-CSF ean increase the number of white blood eell(WBC) and restore inflamation cytokine early.
