摘要
目的观察冠心合剂对冠心病患者PCI术前后血清中NO、ET-1水平的影响以及探讨冠心合剂主要成分(黄芪甲苷、槲皮素、异鼠李素、β谷甾醇)对TNF-α损伤人脐静脉内皮细胞(HUVECs)保护作用的机制。
     方法临床观察选取新近冠脉造影阳性且植入支架的冠心病患者36例,随机分为对照组和治疗组,分别给予基础治疗和基础治疗加冠心合剂治疗,疗程二周后,Elisa法测定两组血清中NO、ET-1水平。细胞实验采用传代后的人脐静脉内皮细胞培养作为实验对象,随机分为正常对照组、模型组、黄芪甲苷组、槲皮素组、异鼠李素组、β谷甾醇组。据前期试验结果,除正常组和模型组外,药物组以各药物成分(浓度分别为黄芪甲苷80μg/ml、槲皮素30μg/ml、异鼠李素20μg/ml、β-谷甾醇20μg/ml)与HUVECs共培养18小时后,模型组和各药物组分别再加入浓度为200ng/ml的TNF-α刺激HUVECs6小时后,分别用RT-PCR检测细胞黏附分子-1、血管细胞粘附分子-1、E-选择素、PAI-1mRNA的表达;以及流式细胞术和Western-blot检测激活蛋白AP-1、核因子NF-кB的表达水平以及HUVECs细胞的凋亡率。
     结果临床观察结果与对照组相比,治疗组NO水平升高有统计学意义(P<0.05),ET-1水平降低明显(P<0.05),和冠心合剂治疗前NO水平亦明显升高(P<0.05),ET-1水平降低明显(P<0.05);两组患者术后与术前相比,NO和ET-1水平两组间差异均无统计学意义(P>0.05)。细胞实验发现①与正常组比较,模型组ICAM-1、VCAM-1、E-sel、PAI-1mRNA的表达有极显著性差异,具有统计学意义(P<0.01);与模型组相较,黄芪甲苷、槲皮素、异鼠李素均可降低TNF-α诱导的HUVECs的ICAM-1、VCAM-1、E-sel、PAI-1mRNA的表达(P<0.05、P<0.05、P<0.05),而与正常组相较差异无统计学意义(P>0.05、P>0.05、P>0.05);而p-谷甾醇组对ICAM-1、VCAM-1、E-sel、PAI-1mRNA的表达抑制不明显,与模型组相较无统计学意义(P>0.05)。②流式细胞术检测细胞凋亡,与正常组比较,模型组凋亡率有显著统计学意义(P<0.01);黄芪甲苷、槲皮素、异鼠李素均可明显降低细胞凋亡率,与模型组相较,黄芪甲苷组具有极显著统计学意义(P<0.01),槲皮素组和异鼠李素组差异也具有显著统计学意义(P<0.05、P<0.05),其中黄芪甲苷组较槲皮素组、异鼠李素组有统计学意义(P<0.05),但与正常组相较,槲皮素组、异鼠李素组仍有明显差异(P<0.05);而p-谷甾醇组对凋亡的抑制作用不明显,差异无统计学意义(P>0.05)。③与正常组比较,模型组激活蛋白AP-1、核因子NF-кB的表达显著上调,有显著统计学意义(P<0.01):黄芪甲苷、槲皮素、异鼠李素均可降低TNF-α诱导的HUVECs的激活蛋白AP-1、转录因子NF-кB的表达(P<0.01、P<0.01、P<0.01),p-谷甾醇组对AP-1和NF-кB的表达无明显抑制作用,差异无统计学意义(P>0.05)。
     结论冠心合剂能够升高冠心病患者PCI术后血清NO并降低ET-1水平。而其主要成分黄芪甲苷等对TNF-α损伤人血管内皮细胞的保护作用可能源于通过对激活蛋白AP-1、核因子NF-кb蛋白表达的抑制,减少细胞凋亡的同时,调节ICAM-1、VCAM-1、E.sel、PAI-1mRNA的表达等途径而实现的。
Objective To observe the influences on ET-1and NO in plasma with the treatment of Guanxin decoction on the basic therapy to the CHD patients treated by PCI in clinical. And in cell experimental reseacrh,we will investigate part protective mechanism of Guanxin Decoction on the HUVECs exposed to TNF-a. Accomplishment of the topic will provide some important experimental evidences for treatment mechanisms of Guanxin Decoction
     Method In clinical Thirty-six CHD patients were randomly divided into the trial group and the control group after treat with PCI recently. The patients of trial group were treated by the Guanxin decoction, and simultaneously accept conventional therapy. as same as the control group. The period of treatment was two week. The level of ET-1and NO in plasma of two groups after treatment were compared by Elisa.In cell experiment, The cultured HUVECs from third to sixth generations were randomly divided into the trial group and the control group(model group, control group, Astragaloside group, Quercetin group, Isorhamnetin group, β-Sitosterol group).Except model group and control group, every research groups cultured with different main active ingredient of Guanxin Decoction level (Astragaloside80μg/ml,Quercetin30μg/ml,Isorhamnetin20ug/ml,β-Sitosterol20μg/ml)for18hours,And then were added TNF-a (2ng/ml),after6hours,ICAM-1、VCAM-1,E-select,PAI-1were detected by reverse transcriptase polymerase chain reaction (RT-PCR) in HUVECs; AP-1and NF-Kb were detected by ANNEXIN-V and Western-blot.
     Result After treatment in clinical, the level of ET-1in plasma of the trial group reduced and the level of NO in plasma rose. Compared with that before treatment and the control group, the results had significant difference (P<0.05),and the level of ET-1and NO in plasma of two groups was no significant difference compared with before PCI (P>0.05). In cell experimental reseacrh,we found①After cultured by TNF-a, Comparing with normal group, the levels of ICAM-1,VCAM-1,E-select,PAI-1mRNA of model group changed insignificantly (P<0.01); except β-Sitosterol group,there were no statistical differences in levels of ICAM-1,VCAM-1, E-select and PAI-1mRNA between treated group and normal control group (P>0.05).And comparing with model group,the expression of ICAM-1,,VCAM-1,E-select and PAI-1mRNA of Astragaloside group,Quercetin group and Isorhamnetin group changed significantly (P<0.01, P<0.01,P<0.01)but β-Sitosterol group.②Comparing with normal group,apoptosis percentage of HUVECs exposed to TNF-a are higher than those in normal group(P<0.01), exsept β-Sitosterol group,there were no statistical differences between treated group and normal control group (P>0.05); And comparing with model group, apoptosis percentage of HUVECs decreased significantly (P<0.01,P<0.01,P<0.01) but P-Sitosterol group.③Comparing with normal group, expression of AP-1and NF-Kb of model group exposed to TNF-a are higher than those in normal group(P<0.01),there were no statistical differences between treated group and normal control group (P>0.05); And comparing with model group, expression of AP-1and NF-Kb were inhibited significantly (P<0.01, P<0.01, P<0.01)but β-Sitosterol group(P>0.05).
     Conclusion Guanxin decoction can improve the level of NO in plasma of CHD patients,and reduce the level of ET-1in clinical. And in cell experimental reseacrh the main active ingredient of Guanxin decoction(Astragaloside,Quercetin and Isorhamnetin) can decrease the expression of ICAM-1,VCAM-1,E-select and PAI-1mRNA on HUVECs exposed to TNF-a;at the same time,can inhibite the expression of AP-1and NF-Kb;and degree apoptosis percentage of HUVECs,but the β-Sitosterol have none of the above.So anti-atherosclerosis of Guanxin decoction maybe realize in this way.
