目的:观察复方丹参滴丸对冠心病患者冠状动脉介入治疗(PCI)后血液流变学的影响,探讨复方丹参滴丸治疗冠心病的临床实用价值。方法:选择确诊冠心病行PCI治疗的患者160例,随机分为治疗组(n=83)和对照组(n=77),对照组于PCI后给予常规用药,包括阿司匹林和氯吡格雷,而治疗组在此基础上,加用复方丹参滴丸口服,于术前和术后3个月,检测并分析其血液流变学指标。结果:与治疗前相比,两组患者在全血粘度高切、中切和低切方面明显降低(P<0.05),且复方丹参滴丸治疗组在治疗后全血粘度低切指标下降更明显,与对照组相比P<0.05,有统计学差异;此外,治疗组在全血还原粘度、红细胞聚集和卡松曲服应力方面与治疗前相比,亦明显降低,具有统计学差异;而对照组治疗后虽有下降趋势,但未达到统计学差异。与对照组相比,复方丹参滴丸治疗组治疗后在全血还原粘度和卡松曲服应力方面水平低于对照组,具有统计学差异(P<0.05)。结论:冠心病PCI后患者在常规用药基础上加用复方丹参滴丸,可明显改善其血流动力学指标,缓解心绞痛症状,具有临床应用价值。     

不同剂量阿托伐他汀短期治疗对急性冠脉综合征患者血清hs—CRP和MMP-9水平的影响

目的探讨应用不同剂量阿托伐他汀短期治疗对急性冠脉综合征患者血清高敏C反应蛋白（hs—CRP）和基质金属蛋白酶-9（MMP-9）水平的影响。方法选择确诊的急性冠脉综合征患者63例,随机分为A组（22例,阿托伐他汀10mg／d）、B组（20例,阿托伐他汀20mg／d）和C组（21例,阿托伐他汀80mg／d）,均于确诊后24小时内开始给药,其余用药按常规进行。所有患者均于服用阿托伐他汀前及服药后24小时、3天、7天采集静脉血,ELISA法测定血清hs—CRP和MMP-9水平。结果3组患者的临床基础资料比较无显著性差异;与治疗前比较服用阿托伐他汀3天后,C组血清hs—CRP和MMP-9水平明显减低（P〈0．05）,而A、B两组虽有下降趋势,但差异无统计学意义;7天后,3组患者血清hs—CRP和MMP-9水平均明显降低（P〈0．05）;C组患者血清hs—CRP和MMP-9水平明显低于A组和B组（P〈0．05）;3组均未发现阿托伐他汀相关不良反应。结论急性冠脉综合征患者短期给予大剂量阿托伐他汀治疗可发挥其强大的抗炎作用,明显降低血浆hs—CRP和MMP-9水平。

 目的：研究慢病毒介导的降钙素基因相关肽（calcitonin gene-related peptide,CGRP）基因转染对大鼠骨髓间充质干细胞（mesenchymal stem cells,MSCs）内皮分化功能的影响。方法：用密度梯度离心结合贴壁法培养大鼠骨髓MSCs,携带CGRP的慢病毒载体转染MSCs,未转染MSCs作为对照,应用ELISA法检测CGRP蛋白表达;实验分为转染Lenti-CGRP的MSCs（CGRP）组、转染Lenti-CGRP的MSCs+CGRP受体拮抗剂（CGRP8-37）组（CGRP +CGRP8-37）及未经转染的对照组。应用免疫细胞化学检测细胞CD31和Ⅷ因子相关抗原的表达以鉴定其分化能力;细胞计数法观察转染CGRP后MSCs增殖的影响;Matrigel实验观察转染CGRP对MSCs形成管腔样结构能力的影响。结果：MSCs转染CGRP基因经诱导分化后的CD31和Ⅷ因子相关抗原阳性细胞数量增多,与对照组相比有显著差异(P<0.05);转染CGRP组细胞数量增长较快,与对照组相比差异有统计学意义(P<0.05);Matrigel实验显示转染CGRP组细胞微血管新生明显,与对照组相比差异有统计学意义(P<0.05)。而CGRP+CGRP8-37组上述作用明显被抑制。结论: 转染CGRP基因能促进MSCs向内皮分化,并能促进内皮细胞增殖,在一定的条件下,可促进微血管新生。     

重组人粒细胞集落刺激因子对兔颈动脉粥样硬化球囊损伤后再内皮化和内膜增生的影响

Objeelive To investigate the effect of rhG-CSF on mobilizing bone marrow-MSCs, reendothelialization and intima hyperplasia in carotid artery of rabbits post balloon catheter injury, nethods Rabbits were treated with rhG-CSF (25 μkg, twice daily, i. p, n =35) or saline (n =32) for 5 days, then, carotid arteries of rabbits were injured by balloon catheter. The number of peripheral MSCs was detected with FACS. The morphology of injuried artery was examined with hematoxylin and eosin stain, PCNA was determined with immunohistochemistry. Results (1) Number of peripheral MSCs was similar at baseline and significantly increased at 24 hours and peaked at 7 days and remained increased till 14 days post rhG-CSF. (2) Significant endothelial cell deletion was evidenced in the control group, while scatter endothelial cells was observed in the rhG-CSF group at 1 week post injury. Two weeks after injury, new endothelial area was significantly higher in rhG-CSF group compared to control group. At 4 weeks post injury, endothelial connection was evidenced and regularly displayed in rhG-CSF treated group. (3) PCNA-positive cells in the tunica intima were significantly lower in rhG-CSF treated rabbits at 7, 14 and 28 days compared that in control rabbits (all P ＜ 0.01). Conclusion rhG-CSF could mobilize the bone marrow-MSCs and promote re-endothelialization and attenuate intima hyperplasia post balloon catheter injury in carotid arteries of rabbits.
