Wenxin capsule can promote endolethial cells releasing CO and synthesing 〓, enhance activity of HO, induce angiectasis through activating guanylic cyclase and adenglate cyclate of intracellar of vessel smooth muscle cell to enhance content of intracellar cGMP and AMP. 3. Wenxin capsule can inhibit releasing of platelet activiting factor 〓 which inhibit platelet aggregation and have antithrombosis function. 4. Wenxin capsule can promote activity of t-PA, reduce activity of PAI-1, strengthen fibrinolytic function, therefore inhibit fibrin disposition. 5. Wenxin capsule can inhibit synthesis of smooth muscle cellular DNA. Its function don't kill it directly but prevent transformation from period Go to peried S. 6. Wenxin capsule is an effective prescription of anti-coronary atherosclerosis atherosis. The results of image pattern analysis tastifies that area of lipid plaque in treating group reduce 54% and 58% in contrast with that in control group. The results of light, electro- microscopy show that structure of endolethial cell and smooth muscle cell in treating group is more integral than that in control group.

其作用机制之一是由于该药具有良好的调脂降脂作用，其不仅能明显降低血清LDL-c及升高HDL-c含量，且能有效阻止TC沉积于血管壁，从而保护内皮细胞结构完整；此外，温心胶囊尚具有明显的抗氧化作用，该药不仅能明显降低血浆LPO含量，且能提高SOD活性，同时其对血红素在细胞内代谢的调节作用也参与了抗氧化过程。2 温心胶囊能明显促进内皮细胞释放CO及合成〓，提高HO活性，通过激活血管平滑肌细胞内鸟苷酸环化酶及腺苷酸环化酶引起细胞内cGMP、AMP浓度增加而引起血管舒张。3 温心胶囊能明显抑制血小板激活因子〓的释放，从而抑制血小板聚集，抗血栓形成。4 温心胶囊能明显提高t-PA活性，降低PAI-1活性，增强纤溶功能，从而抑制纤维蛋白沉积。5 温心胶囊能明显抑制平滑肌细胞DNA合成，其抑制作用不是直接杀伤抑制，而是阻止细胞由Go期向S期转化。6 温心胶囊是抗冠状动脉粥样硬化的有效制剂，图象分析结果证实，该药治疗组脂斑面积比对照组缩小了54％和58％，光电镜结果显示内皮细胞及平滑肌细胞结构较为完整。
