目的　利用前瞻性随机对照方法比较全主动脉弓替换术中单侧顺行性脑灌注 (ASCP)和双侧ASCP时视网膜中央动脉、球后血管血流变化和血S1 0 0蛋白浓度变化。方法　 1 6例全主动脉弓替换术患者随机分为单侧AS CP和双侧ASCP组 ,每组各 8例。两组均行术前术后颅脑计算机体层摄影 (CT)。术中采用经眼球超声监测视网膜中央动脉及球后血管血流。术中术后动态测定血S1 0 0蛋白浓度。结果　两组各有 1例出现短暂性神经功能异常。ASCP过程中单侧组右侧视网膜中央动脉可探及血流 ,左侧视网膜中央动脉不可探及 ,双侧组两侧视网膜中央动脉均可探及血流。所有患者球后动脉均可探及血流。两组间各阶段血S1 0 0蛋白浓度无显著性差异 (P >0 .0 5 )。结论　在基底动脉环完整 ,存在有效侧支循环条件下 ,单侧灌注操作较为简便 ,双侧灌注在ASCP期间两侧脑灌注较为均衡 ,但两种灌注方法对S1 0 0蛋白浓度的影响无显著性差异。     

Normal cerebral perfusion measurements using arterial spin labeling: reproducibility, stability, and age and gender effects.

Before meaningful conclusions can be drawn from clinical measures of cerebral blood perfusion, the precision of the measurement must be determined and set in the context of inter- and intrasubject sources of variability. This work establishes the reproducibility of perfusion measurements using the noninvasive MRI technique of continuous arterial spin labeling (CASL). Perfusion was measured in 34 healthy normal subjects. Intersubject variability was assessed, and age and gender contributions were estimated. Intersubject variation was found to be large, with up to 100% perfusion difference for subjects of the same age and gender. Repeated measurements in one subject showed that perfusion remains remarkably stable in the short term when compared with intersubject variation and the large capacity for perfusion change in the brain. A significant decrease in the ratio of gray-matter to white-matter perfusion was found with increasing age (0.79% per year (P < 0.0005)). This appears to be due mainly to a reduction in gray-matter perfusion, which was found to decrease by 0.45% per year (P = 0.04). Regional analysis suggested that the gray-matter age-related changes were predominantly localized in the frontal cortex. Whole-brain perfusion was 13% higher (P = 0.02) in females compared to males.     

小剂量阿司匹林对缺血性脑血管病患者血小板聚集功能的影响

目的 :观察小剂量阿司匹林 (ASA)对ICVD患者血小板聚集功能的影响。方法 :用花生四烯酸 (AA ,5 0 0 μmol·L-1)、二磷酸腺苷 (ADP ,5 μmol·L-1)、肾上腺素 (EPN ,5 μmol·L-1)和胶原 (COL ,2 μg·mL-1)做诱导剂检测ICVD患者服用不同剂量ASA组 ( 2 5、5 0和10 0mg·d-1)的血小板聚集率。结果 :各ASA组对AA、COL诱导聚集的变异系数较大。对AA诱导聚集无显著抑制者的比例分别为2 5mg·d-1组 44 4%、5 0mg·d-1组 2 9 6%、10 0mg·d-1组 2 9% ,其中 5 0mg·d-1组中合并糖尿病的例数较显著抑制者中多。结论 :ICVD患者中小剂量ASA作用个体差异较大 ,部分与自身危险因素有关。提示临床中ASA的效果需要实验室检测并应个体化

Effect of electro-acupuncture combined with early rehabilitation on motor function and expressions of CD11b/CD18 and tumor necrosis factor-α in patients with acute cerebral infarction

Objective To observe the effect of electro-acupuncture combined with early rehabilitation on the motor function and expressions of the adhesion molecules CD11b and CD18 in the polymorphonuclear leucocytes (PMN) and monocytes and serum tumor necrosis factor-α (TNF-α) levels in patients with acute cerebral infarction (ACI). Methods A total of 165 ACI patients were randomly divided into control group (group A, n=50), conventional rehabilitation group (group B, n=50) and comprehensive rehabilitation group (group C, n=65). The expressions of CD11b and CD18 in the PMN and monocytes and serum TNF-α levels were determined before and at 1, 2, and 4 weeks after the treatment. Thirty-two healthy subjects were also recruited as the normal control group (group N). The neurological function of the subjects was evaluated by modified Edinburgh-Scandinavia stroke scale (MESSS) and Fugi-Meyer Assessment (FMA), and their activity of daily living (ADL) was assessed using Barthel index (BI). Results The CD11b/CD18 expression in the PMN and MN and serum TNF-α level in groups A, B and C were significantly higher than those in group N before and 1 week after the treatment (P<0.05). CD11b/CD18 expression and serum TNF-α level were significantly lower in groups B and C than in the group A at 1 week after the treatment, and significantly lower in group C than in group B (P<0.05). At 2 weeks of treatment, CD11b/CD18 and TNF-α were significantly lower in groups B and C than in the group A, being the lowest in group C (P<0.05). The scores of mESSS in both groups B and C were lower than that in group A, and the scores were lower in group C than in group B. Group C showed higher FMA scores than group B, both having higher scores than group A. At 4 weeks of treatment, the mESSS scores were significantly lower, hut the FMA and ADL score significantly higher in groups B and C than in the control group (P<0.05), and the differences were more obvious in group C. Groups B and C had greater effective rate than group A (P<0.05), and the rate was the highest in group C (P<0.05). Conclusion Electro-acupuncture combined with early rehabilitation promotes the recovery of motor function in ACI patients probably by regulating the expressions of the adhesion molecules CD11b and CD18 on the PMN and monocytes and the serum levels of TNF-α.
