脑梗死患者外周血CD34+细胞水平和预后价值

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.

Abstract：

Objective To analyze the changes of the intima-media thickness(IMT)of carotid and femoral arteries, serum advanced glycosylation end-products(AGEs),and AGEs soluble receptor(sRAGE)after intensively controlling blood glucose, blood pressure, and lipid. Methods One hundred and thirty-two type 2 diabetic patients were divided into 3 groups and followed for 5 years: 20 patients were treated with intensive control of blood glucose and blood pressure, 80 patients with intensive control of blood glucose, blood pressure, and lipid; and 32 patients with conventional therapy. AGEs, sRAGE, and IMT of carotid and femoral arteries were measured and compared among different groups. Results The IMT of carotid and femoral arteries and serum level of AGEs were significantly decreased after intensive treatment. The ratio of sRAGE and HbA1C(sRAGE/HbA1C)were negatively correlated with the mean of HbA1Cin the past five years(r=-0.417, P＜0.001)and the fluctuation of HbA1C(r=-0.309,P＜0.001). Multinomial regression analysis showed that AGEs were the important risk factors of IMT of femoral artery(β=0.152,P=0.068). Conclusion Intensive treatment is significant in controlling the growing IMT of carotid and femoral arteries, while decreasing serum level of AGEs.

目的研究急性脑梗死（ACI）患者血清基质金属蛋白酶-9（MMP-9）的水平与颈动脉粥样硬化及病情的关系。方法选取首次发病的ACI患者100例,其中小面积梗死38例、中面积梗死42例、大面积梗死20例,健康对照组30例。采用双抗体夹心酶联免疫吸附试验（ELISA）测定血清MMP-9的水平。应用颈动脉超声检测颈动脉内膜状况。比较不同程度颈动脉粥样硬化及不同面积脑梗死患者血清MMP-9的水平变化,并对所有ACI患者进行神经功能缺损评分。结果ACI患者血清MMP-9的水平显著高与对照组（P〈0．01）;大梗死组患者血清MMP-9水平高于中、小梗死组,中梗死组高于小梗死组,差异均有统计学意义（P〈0．01）;随着颈动脉粥样硬化程度加重血清MMP-9的水平呈上升趋势;ACI患者脑梗死面积及神经功能缺损评分与血清MMP-9的水平呈正相关（r1=0．553,P〈0．01;r2=0．536,P〈0．01）。结论ACI患者血清MMP-9水平可以反映颈动脉斑块的性质和稳定性,亦可反映脑梗死面积与病情的严重程度。     

基质金属蛋白酶-3、高敏C-反应蛋白与颈动脉粥样硬化和急性脑梗死的关系

目的:探讨基质金属蛋白酶-3(MMP-3)、高敏C-反应蛋白(hs-CRP)与颈动脉粥样硬化和急性脑梗死的关系.方法:64例首次发病的脑梗死患者和20例健康体检者,应用酶联免疫双抗体夹心法测定血清MMP-3浓度,免疫散射比浊法测定血清hs-CRP浓度.应用颈动脉超声检测颈动脉内膜状况,并对急性脑梗死患者进行神经功能缺损评分.结果:急性脑梗死患者血清MMP-3和hs-CRP浓度显著高于正常对照组(P＜0.01).不稳定斑块组(混合斑块组、软斑组)血清MMP-3和hs-CRP浓度显著高于稳定斑块组(硬化斑块组)和内膜毛糙组(P＜0.01).血清MMP-3和hs-CRP浓度分别与急性脑梗死患者神经功能缺损评分呈正相关.结论:急性脑梗死患者血清MMP-3和hs-CRP水平可以反映颈动脉斑块的性质和稳定性,是临床了解脑梗死严重程度的重要指标.
