[Abstract] Objective To study the expression levels of serum CRP, TNF-α and blood lipids in the patients with coronary heart disease complicated with unstable angina, and to investigate the relationship between the three factors of CRP, TNF-α and blood lipid and coronary heart disease complicated with unstable angina. Methods The clinical data of 46 patients with unstable angina and 40 patients with stable angina who were admitted to our hospital from August 2015 to September 2016 were collected, and an overall analysis was made; the expression levels of serum CRP, TNF-α and blood lipids were measured in the patients with two types of diseases and healthy controls. Results The results of ELISA showed that the expression levels of serum CRP and TNF-α in the patients with unstable angina pectoris were significantly increased compared with the control group, and the LDL-C and TG levels were also increased. Compared with the control group, there were significant differences(P<0.05); the levels of serum CRP, LDL-C and TG in the patients with stable angina were increased, and the difference was statistically significant(P<0.05). However, TNF-α, HDL-C and TC levels did not change significantly compared with those in the healthy controls, and the difference was not statistically significant(P>0.05). Conclusion CRP, TNF-α and blood lipids may be closely related to the occurrence and development of coronary heart disease complicated with unstable angina. Detection of serum CRP, TNF-α and blood lipids levels in the patients with coronary heart disease complicated with unstable angina is of great significance to understand the immune status, clinical diagnosis and prognosis of the patients.endprint

冠心病不安稳型心疼痛(unstable angina,UA)是介于安稳型心疼痛与急性心肌梗死及心脏猝死之间的一种临床状况,其发病原因与年纪添加、高血脂、糖尿病和肾功能妨碍等相关疾病、动脉粥样硬化和血管壁斑块决裂等密切相关[1]。研讨标明,机体炎症反响和相关细胞因子是引起粥样血栓的首要因素,而单核巨噬细胞又在此进程中起关键效果,由其发作并排泄的肿瘤坏死因子-α(TNF-α)及其诱导肝脏发作的急性反响蛋白C-反响蛋白(CRP)是炎症和免疫反响的重要介质。这些炎症因子和血脂在冠状动脉斑块的发作开展及不安稳性斑块决裂而激起的血栓构成进程中可能起重要效果[2]。本文首要检测了安稳型心疼痛患者和不安稳型心疼痛患者血清中CRP、TNF-α和血脂(LDL-C、HDL-C、TC和TG)的水平,与正常人群进行比较,以评论这三者在不安稳型心疼痛患者血清中的改动以及在不安稳型心疼痛发病机制中的效果,以为临床上开发UA新的医治办法供给实验依据,并为UA的临床确诊和病况判别供给指导含义。

3 评论

依据修订的心肌梗死(MI)界说,患有缺血、但其间生物标志物仅有细微升高和下降的患者,现被以为具有真实的心肌损害[4]。从2000年至今,不安稳型心疼痛经过区分肌钙蛋白阳性和肌钙蛋白阴性来区分,因而,1989年对不安稳型心疼痛的临床界说仍是最合适的描绘[5]。心疼痛被以为在心肌的冠状血管上血流被掠夺导致的一种胸部不适状况[6],安稳型心疼痛首要是心外膜冠状动脉内腔削减引起冠状动脉粥样硬化[7],而不安稳型心疼痛是一种心脏没有得到满足血流量和氧气的状况[8],可能导致心脏病发作。

CRP是一种由单核细胞组成的急性期反响蛋白,在IL-6的诱导下发动凝血进程[9]。CRP经过结合磷酸胆碱发挥生物学活性,在即将逝世或许现已逝世的细胞外表影响免疫体系[10,11]。TNF-α是一种具有多种生物活性的细胞因子,首要参加抗感染、机体免疫调节以及增强单核细胞的活性,在机体免疫防护体系中起重要效果[12]。TNF-α首要由巨噬细胞排泄,并以自排泄方法促进本身的组成,会集组成在病变部位,各类感染和外界影响均能引起TNF-α的表达添加。生理状况或激活状况下的TNF-α均能按捺血管平滑肌细胞的胶原基因表达,使斑块不安稳。TNF-α可促进原癌基因的表达,发作血小板生长因子,使血凝-抗凝体系失衡,促进血栓的构成,引起不安稳型心疼痛的发作[13]。血清中总胆固醇(TC)和低密度脂蛋白胆固醇(LDL-C)是冠状动脉疾病的临床表现[14],而冠状动脉粥样硬化和血栓构成可导致冠心病的构成。研讨标明,血脂在不安稳型心疼痛的发作开展中可能有必定效果。endprint

本研讨成果标明,不安稳型心疼痛患者血清中CRP、TNF-α、低密度脂蛋白胆固醇(LDL-C)和甘油三酯(TG)的含量均显着高于安稳型心疼痛患者和正常对照人群;比较正常人群和安稳型心疼痛患者,不安稳型心疼痛患者血脂表达水平显着下降。比较正常对照人群,安稳型心疼痛患者血清中CRP、TG和LDL-C水平显着升高,而TNF-α、TC和HDL-C水平无显着差异。此成果提示CRP、TNF-α、TG和LDL-C在动脉粥样硬化的发作开展中具有重要效果,也可能是不安稳型心疼痛的重要發病机制之一[15]。关于CRP、TNF-α和血脂在冠心病不安稳型心疼痛的发病中详细分子机制及怎么参加调控UA的开展,还有待进一步研讨。
