研究目的:

(1)临床资料特征:研究分析纳入40例丽水市地区ACS患者的临床资料特征,包括年龄、性别、BMI、吸烟史、饮酒史、用药史等方面的数据。 (2)丹酚酸A对血小板聚集和刺激剂引起的血小板激活的影响:探究丹酚酸A对不同刺激剂(ADP和凝血酶)诱导的血小板聚集的影响;探究丹酚酸A对不同刺激剂(ADP和凝血酶)引起的血小板激活的影响。 (3)丹酚酸A抗血小板作用在ACS三种不同类型之间的比较:探究丹酚酸A对不同类型ACS患者的抗血小板效果。 (4)丹酚酸A对ACS合并高血压患者血小板功能的影响:探究丹酚酸A对ACS合并高血压和未合并高血压两组患者血小板聚集和活化影响的差异性。 (5)丹酚酸A抗血小板作用效果的相关因素分析:探究影响丹酚酸A抗血小板作用效果的相关因素

Objectives of Study:

(1) Clinical Data Characteristics: The study analyzed the clinical data characteristics of 40 ACS patients from the Lishui area including data on age gender BMI smoking history drinking history and medication history. (2) The Effect of Salvianolic Acid A on Platelet Aggregation and Platelet Activation Induced by Agonists: To explore the impact of Salvianolic Acid A on platelet aggregation induced by different agonists (ADP and thrombin); to investigate the effect of Salvianolic Acid A on platelet activation caused by different agonists (ADP and thrombin). (3) Comparison of the Antiplatelet Effect of Salvianolic Acid A Among Three Different Types of ACS: To explore the antiplatelet effects of Salvianolic Acid A in patients with different types of ACS. (4) The Impact of Salvianolic Acid A on Platelet Function in ACS Patients with Hypertension: To investigate the differences in the impact of Salvianolic Acid A on platelet aggregation and activation between ACS patients with and without hypertension. (5) Analysis

药物成份或治疗方案详述:

丹酚酸A(Salvianolic acid A,SAA)是一种从丹参中提取的化合物,具有多种药理学作用,比如抑制血管平滑肌细胞的增殖和迁移,促进泡沫细胞凋亡,抑制动脉粥样硬化的形成和发展,以及减轻心肌炎症反应等。其中最为重要的是其抗血小板作用。即从中医学角度看具有活血化瘀功效。丹酚酸A能够抑制血小板聚集,其作用机制主要包括抑制血小板TXA2的合成、抑制血小板钙离子内流、抑制血小板活化等。

Description for medicine or protocol of treatment in detail:

Salvianolic acid A (SAA) is a compound extracted from Danshen (Salvia miltiorrhiza) which possesses a variety of pharmacological effects. These include inhibiting the proliferation and migration of vascular smooth muscle cells promoting the apoptosis of foam cells suppressing the formation and development of atherosclerosis and alleviating myocardial inflammatory responses among others. The most important of these is its antiplatelet action. From the perspective of traditional Chinese medicine it has the effect of promoting blood circulation and removing blood stasis. SAA can inhibit platelet aggregation and its mechanisms of action mainly include inhibiting the synthesis of platelet TXA2 inhibiting the influx of calcium ions into platelets and inhibiting platelet activation.
