目的 觀察冠心病患者血清不規(guī)則趨化因子(FKN)、基質(zhì)金屬蛋白酶9(MMP-9)以及單核細(xì)胞趨化蛋白1(MCP-1)的水平變化。方法 選擇2014年6月~10月在阜陽市人民醫(yī)院心血管內(nèi)科住院的冠心病患者共144例,男性74例,女性70例,平均年齡(64.9±10.1)歲。其中穩(wěn)定型心絞痛(SAP)組45例,不穩(wěn)定型心絞痛(UAP)組55例,急性心肌梗死(AMI)組44例。另選取同期本院健康體檢者50例作為對(duì)照組。采用ELISA法檢測(cè)血清FKN、MMP-9以及MCP-1水平。結(jié)果 與對(duì)照組比較,SAP組、UAP組及AMI組的FKN、MMP-9、MCP-1水平明顯增高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05);與SAP組比較,UAP組和AMI組的FKN、MMP-9、MCP-1水平明顯升高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05);與UAP組比較,AMI組上述三項(xiàng)因子水平均明顯增高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05)。結(jié)論 血清FKN、MMP-9以及MCP-1水平在冠心病患者中明顯升高,有助于監(jiān)測(cè)冠心病嚴(yán)重程度。

冠狀動(dòng)脈粥樣硬化性心臟?。ü谛牟。┦且环N多因素疾病,其中炎癥反應(yīng)參與了冠狀動(dòng)脈硬化斑塊形成、破裂的過程,對(duì)冠心病的發(fā)生、發(fā)展有重要的促進(jìn)作用[1,2]。近年來有研究發(fā)現(xiàn)血清不規(guī)則趨化因子(FKN)、基質(zhì)金屬蛋白酶9 (MMP-9)以及單核細(xì)胞趨化蛋白1(MCP-1)等與冠心病的發(fā)生有關(guān)[3-5]。本研究旨在觀察冠心病患者FKN、MMP-9和MCP-1的水平變化,并進(jìn)一步探討其臨床意義。
1.1研究對(duì)象和分組 選擇2014年6月~10月在阜陽市人民醫(yī)院心血管內(nèi)科住院的冠心病患者共144例,男性74例,女性70例,平均年齡(64.9± 10.1)歲。其中穩(wěn)定型心絞痛(SAP)組45例,不穩(wěn)定型心絞痛(UAP)組55例,急性心肌梗死(AMI)組44例。另選取同期本院健康體檢者50例作為對(duì)照組,其中男性26例,女性24例,平均年齡(65.1±10.3)歲。
2.1一般資料比較 各組患者性別、年齡、合并疾病比例、血脂和體質(zhì)指數(shù)等比較,差異均無統(tǒng)計(jì)學(xué)意義(P均>0.05)(表1)。
2.2各組FKN、MMP-9和MCP-1水平比較 與對(duì)照組比較,SAP組、UAP組及AMI組的FKN、MMP-9、MCP-1水平明顯增高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05);與SAP組比較,UAP組和AMI組的FKN、MMP-9、MCP-1水平明顯升高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05);與UAP組比較,AMI組上述三項(xiàng)因子水平均明顯增高,差異有統(tǒng)計(jì)學(xué)意義(P均<0.05)(表2)。

研究發(fā)現(xiàn)炎癥細(xì)胞浸潤(rùn)、炎癥反應(yīng)以及脂質(zhì)代謝異常等因素導(dǎo)致冠狀動(dòng)脈發(fā)生粥樣硬化、粥樣硬化斑塊失穩(wěn)破裂以及血栓形成,進(jìn)一步導(dǎo)致冠狀動(dòng)脈管腔狹窄、阻塞和/或冠狀動(dòng)脈痙攣,心肌發(fā)生缺血、缺氧或壞死[1,2]。本研究以炎癥因子FKN、MCP-1以及MMP-9為研究指標(biāo),檢測(cè)冠心病患者其水平變化。
FKN是同時(shí)具有黏附和趨化活性的趨化因子,能趨化和激活白細(xì)胞而參與炎癥反應(yīng)的各個(gè)階段,包括黏附、遷移、清除致炎物質(zhì)、修復(fù)等。研究發(fā)現(xiàn)FKN在心腦血管疾病、慢性阻塞性肺疾病、腫瘤等疾病的發(fā)生、發(fā)展中均發(fā)揮作用。在冠心病的進(jìn)展過程中,損傷的內(nèi)皮細(xì)胞、巨噬細(xì)胞源性泡沫細(xì)胞以及冠狀動(dòng)脈斑塊中均有FKN過度表達(dá)[9,10]。本研究發(fā)現(xiàn),SAP組、UAP組、AMI組FKN水平高于對(duì)照組,SAP組、UAP組和AMI組,F(xiàn)KN水平逐漸升高。
活化的單核/巨噬細(xì)胞以及T淋巴細(xì)胞可分泌多種細(xì)胞因子,如hs-CRP、II-6、MMP-9、MCP-1等,可直接誘發(fā)并進(jìn)一步加重炎癥反應(yīng)對(duì)機(jī)體的損傷作用。其中,MCP-1是作用很強(qiáng)的單核細(xì)胞趨化因子,可調(diào)節(jié)血管內(nèi)皮表達(dá)相關(guān)黏附分子,具有調(diào)節(jié)單核細(xì)胞黏附和進(jìn)入動(dòng)脈壁的雙重功能,同時(shí),在動(dòng)脈硬化過程的后期,MCP-1在促進(jìn)斑塊不穩(wěn)定性中起到了重要的作用[5,11]。鑒于MCP-1在動(dòng)脈硬化疾病發(fā)生、發(fā)展中的重要影響,許多研究開展了以MCP-l為治療靶點(diǎn)的研究,包括基因治療、藥物治療等,為動(dòng)脈硬化疾病的臨床治療提供了新的思路[12,13]。MCP-1還可定向趨化并刺激單核/巨噬細(xì)胞合成IL-6和MMP-9等細(xì)胞因子[14]。MMP-9是基質(zhì)金屬蛋白酶(MMPs)家族的重要成員之一,是降解細(xì)胞外基質(zhì)最重要的酶類,維持血管形態(tài)和功能的完整性。MMP-9降解基質(zhì)膠原和彈性蛋白,削弱斑塊的穩(wěn)定性,誘發(fā)血栓形成,觸發(fā)急性心血管疾病的發(fā)生[3,15-17]。本研究發(fā)現(xiàn),SAP組、UAP組、AMI組MMP-9以及MCP-1水平高于對(duì)照組,且SAP組、UAP組到AMI組,MMP-9、MCP-1水平逐漸升高。
綜上所述,炎癥因子FKN、MCP-1以及MMP-9在冠心病的發(fā)生、發(fā)展過程中起著重要作用,通過檢測(cè)上述因子的水平,有助于了解病情變化并及早做出相關(guān)干預(yù),對(duì)冠心病患者的治療有重要的臨床意義。

Objective To observe the changes of serum fractalkine (FKN), matrix metalloproteinase-9 (MMP-9) and monocyte chemoattractant protein-1 (MCP-1) in patients with coronary heart disease (CHD). Methods CHD patients (n=144, male 74, female 70 and average age=64.9±10.1) were chosen from Jun. 2014 to Oct. 2014. The patients were divided into stable angina pectoris group (SAP group, n=45), unstable angina pectoris group (UAP group, n=55) and acute myocardial infarction (AMI group, n=44). Other 50 heath controls were chosen as control group. The levels of FKN, MMP-9 and MCP-1 were detected by using enzyme-linked immunosorbent assay (ELISA). Results Compared with control group, the levels of FKN, MMP-9 and MCP-1 increased significantly in SAP group, UAP group and AMI group (all P<0.05). Compared with SAP group, the levels of FKN,MMP-9 and MCP-1 increased significantly in UAP group and AMI group (all P<0.05). Compared with UAP group,the levels of FKN, MMP-9 and MCP-1 increased significantly in AMI group (all P<0.05). Conclusion The levels of serum FKN, MMP-9 and MCP-1 increase significantly in CHD patients, which is helpful for monitoring the severity of CHD.
