摘　　要：目的探讨复方丹参注射液对冠心病患者硝酸酯耐药的影响及机制。方法将 84例入选冠心病患者随机分为 3组 :A组 (消心痛组 )、B组 (消心痛加复方丹参注射液组 )、C组 (消心痛加维生素C组 ) ,3组消心痛用法均为 15mg ,每天 4次 ,治疗时间均为 10天。观察临床耐药情况、血压 ,分别于治疗前后用彩色多普勒检测肱动脉基础内径值 (D0 )、加压后肱动脉舒张反应〔D1,即血流介导血管内径扩张 (flow mediat edvasodilation ,FMD)〕和含服硝酸甘油后的血管舒张反应 (D2 ) ,并采血检测内皮素 1(endothelin 1,ET 1)、内皮源型一氧化氮合酶 (endothelialnitricoxidesynthase ,eNOS)基因mRNA表达。内皮依赖性血管舒张功能 (endothelial dependentvasodilation ,EDD)以 (D1-D0 ) /D0× 10 0 %表示 ,非内皮依赖性血管舒张功能 (en dothelial independentvasodilation ,EID)以 (D2 -D0 ) /D0× 10 0 %表示。结果 (1)B(2 8 5 7% )、C(35 71% )两组临床耐药的发生率明显低于A组 (6 4 2 8% ) ,B、C组间差异无显著性。 (2 )治疗后A组血压回升 ,与治疗前比较差异无显著性 ;C组虽有回升 ,但仍较治疗前低 ;B组无明显回升。B、C组间比较差异有显著性 (P<0 0 5 )。 (3)治疗后A组EID降低 ,B、C组EDD提高 (P <0 0 5 ) ,B。Objective To investigate the effect and mechanism of Compound Salvia injection (CSI) on nitrate ester tolerance. Methods Eighty four patients with coronary heart disease (CHD) were randomly divided into three groups, Group A treated with isosorbide dinitrate (ISD, 15 mg, 4 times per day) alone, Group B with ISD plus CSI and Group C with ISD plus vitamin C. The therapeutic course for all groups was 10 days. The tolerance to nitrate ester and blood pressure were monitored. Before and after treatment, the color Doppler ultrasonic apparatus was used to detect the baseline value of humeral arterial internal diameters (D0), the humeral arterial dilatory response under compression 〔D1, that is, the flow mediated vasodilation (FMD)〕 and the vasodilatory response after sucking of nitroglycerin (D2). And the blood levels of endothelin 1 (ET 1), endothelial nitric oxide synthase (eNOS) mRNA expression were determined. The endothelial dependent vasodilation (EDD) was expressed by (D1-D0)/D0×100%, and the endothelial independent vasodilation (EID) was expressed by (D2-D0)/D0×100%. Results (1)The occurrence rate of nitrate tolerance in Group B and C (28.57% and 35 7%) was lower than that in Group A (64.29%), but insignificant difference was found between the former two. (2) After treatment, blood pressure increased in Group A to the level of pre treatment, that in Group C also increased but still lower than that of pre treatment, while insignificant increase was observed in Group B, comparison between Group B and C showed significant difference ( P <0 05). (3) After treatment, EID lowered in Group A, EDD increased in Group B and C ( P <0 05), EDD and EID in Group B and C were higher than those in Group A ( P <0 05), and EDD was higher in Group B than in Group C ( P <0 05). (4) After treatment, ET 1 mRNA expression lowered in Group B, eNOS mRNA expression increased in Group B and C, with significant difference as compared with those before treatment and those in Group A ( P <0 05), and eNOS m
