[摘要]目的分析冠心病合并抑郁癥患者血清脂聯(lián)素水平及其與炎性因子的相關(guān)性。方法選用110例冠狀動(dòng)脈造影檢查確診的冠心病患者,根據(jù)漢密爾頓抑郁評分,分為冠心病合并抑郁癥組52例和冠心病非抑郁組各58例,另外選取60例正常對照組,測定其血清脂聯(lián)素(APN)、IL-6、TNF-a、hs-CRP水平。結(jié)果冠心病組患者血清IL-6(136± 18.6)ng/L、TNF-a(15.6±9.5)ng/L、hs-CRP(4.6±3.1)mg/L,均顯著高于對照組(P<0.01),血清APN(12.12±3.76)mg/L顯著低于對照組(P<0.01);冠心病合并抑郁癥患者血清IL-6(166.2±21.6)ng/L、TNF-a(18.2±12.0)ng/L、hs-CRP(10.2±3.4)mg/L顯著高于冠心病非抑郁癥組(P<0.01),血清脂聯(lián)素顯著低于對照組(P<0.01),且冠心病合并抑郁癥組血清脂聯(lián)素水平與炎性因子IL-6、TNF-a、hs-CRP呈顯著的負(fù)相關(guān)性(r值分別為-0.560,-0.462,-0.268,P<0.01)。結(jié)論冠心病合并抑郁癥組血清脂聯(lián)素水平明顯減低,而炎性因子IL-6、TNF-a、hs-CRP均顯著增高,這些炎性因子對脂聯(lián)素具有一定的抑制作用,從而增加冠心病的發(fā)病率及冠心病患者并發(fā)抑郁癥的可能。
[關(guān)鍵詞]冠心??;抑郁癥;血清脂聯(lián)素;炎性因子
脂聯(lián)素,又稱脂連蛋白(adiponectin,APN),是一種主要由脂肪細(xì)胞分泌的蛋白質(zhì)激素,大量存在于血液循環(huán)中,其水平與脂肪儲(chǔ)量呈負(fù)相關(guān),具有抗炎、抗動(dòng)脈粥樣硬化形成和血管損傷后抗內(nèi)膜增生的作用。研究顯示[1],脂聯(lián)素與腫瘤壞死因子(TNF)分泌、脂肪和糖類的代謝、動(dòng)脈平滑肌增殖和遷移以及血管內(nèi)皮分泌功能都有密切關(guān)系。目前,血清脂聯(lián)素與冠心病合并抑郁癥患者炎性因子水平的相關(guān)研究尚不充分,該研究對2013年9月—2014年4月整群選取的110例在中大醫(yī)院心內(nèi)科就診的冠心病患者進(jìn)行臨床檢測,分析了冠心病合并抑郁患者血清脂聯(lián)素水平及其與炎性因子的相關(guān)性,報(bào)道如下。
1.1一般資料
該研究整群選取就診于東南大學(xué)附屬中大醫(yī)院心內(nèi)科療區(qū),行冠狀動(dòng)脈造影檢查確診的冠心病患者110例為研究對象,根據(jù)漢密爾頓抑郁量表(HAMD)評分評分測試[2],選取分?jǐn)?shù)>7分者(輕度及中重度抑郁患者)52例作為冠心病合并抑郁組,其中男性患者293例,女性患者23例,平均年齡(68.71±15.81)歲;選取冠心病非抑郁患者58例作為冠心病非抑郁癥組,其中男性患者30例,女性患者28例,年齡(67.31±15.49)歲;另選經(jīng)知情同意參加臨床研究者60例作為正常對照組,其中男30例,女30例,平均年齡(66.34±15.01)歲,經(jīng)體檢確定身體健康無重大疾病。
1.2研究方法
所有研究對象于清晨空腹進(jìn)行靜脈采血5 mL,于無菌離心管中分離血清后集中,采用酶聯(lián)免疫吸附試驗(yàn)(EllSA)檢測血清IL-6、TNF-a、hs-CRP的含量,測試儀器。
1.3統(tǒng)計(jì)方法
采用SPSS 19.0統(tǒng)計(jì)學(xué)軟件對數(shù)據(jù)進(jìn)行處理,計(jì)量資料均以均數(shù)±標(biāo)準(zhǔn)差(±s)表示,比較采用t檢驗(yàn),計(jì)數(shù)資料以百分?jǐn)?shù)表示,應(yīng)用x2檢驗(yàn)。單因素相關(guān)分析應(yīng)用Pearson相關(guān)分析,多元逐步回歸分析APN的相關(guān)因素。P<0.05表示差異無統(tǒng)計(jì)學(xué)意義。
血清APN、IL-6、TNF-a、hs-CRP測定結(jié)果顯示,冠心病組患者血清IL-6、TNF-a、hs-CRP水平均顯著高于對照組,差異有統(tǒng)計(jì)學(xué)意義(P<0.01),血清APN顯著低于對照組,差異有統(tǒng)計(jì)學(xué)意義(P<0.01);冠心病合并抑郁癥患者血清IL-6、TNF-a、hs-CRP水平顯著高于冠心病組,差異有統(tǒng)計(jì)學(xué)意義(P<0.01),血清APN顯著低于對照組,差異有統(tǒng)計(jì)學(xué)意義(P<0.01),見表1。

注:冠心病組與對照組,P<0.01;冠心病合并抑郁癥組與冠心病組,P<0.01。
冠心病合并抑郁癥組(n=52)冠心病非抑郁癥組(n=58)對照組(n=60)t值P值組別9.44±2.98 12.12±3.76 15.98±4.66 3.012 0.004 APN (mg/L)166.2±21.6 136±18.6 109.5±15.5 3.345 0.007 APN (mg/L)18.2±12.0 15.6±9.5 7.2±10.3 3.113 0.003 10.2±3.4 4.6±3.1 1.3±1.5 3.598 0.008 TNF-a (ng/L)TNF-a (ng/L)
以血清APN水平為因變量,各指標(biāo)為自變量進(jìn)行Pearson相關(guān)分析顯示IL-6、TNF-a、hsC-RP與APN呈負(fù)相關(guān)。冠心病合并抑郁癥組血清脂聯(lián)素水平與炎性因子的相關(guān)性分析見表2。
表2 冠心病合并抑郁癥組血清脂聯(lián)素水平與炎性因子的相關(guān)性分析
冠心病發(fā)病機(jī)制與機(jī)體的免疫反應(yīng)及炎癥反應(yīng)密切相關(guān)[3]。血清脂聯(lián)素可以抑制TNF-a、IL-6等炎性因子的表達(dá),參與心肌抗炎,具有保護(hù)心肌細(xì)胞缺血再灌注損傷,在動(dòng)脈硬化斑塊的發(fā)展過程中發(fā)揮作用[4-7]。
在冠心病患者由于癥狀、心理等方面因素的影響導(dǎo)致臨床上合并抑郁癥患者逐漸增多,特別在患者癥狀急性發(fā)作時(shí)[8-11]。國外有研究報(bào)道單純抑郁癥患者血清IL-6、TNF-a、hs-CRP等炎性因子是升高的。
但目前國內(nèi)外尚未有針對冠心病合并抑郁癥患者的血清脂聯(lián)素水平及其相關(guān)炎性因子的研究。該研究中,冠心病合并抑郁癥組血清APN顯著低于對照組及冠心病組(P<0.01),血清IL-6、TNF-a、hs-CRP水平顯著高于冠心病組(P<0.01),其血清脂聯(lián)素水平與炎性因子呈顯著的負(fù)相關(guān)性,提示在冠心病形成的過程中炎性因子對脂聯(lián)素具有一定的抑制作用,從而增加冠心病的發(fā)病率及其并發(fā)抑郁癥的可能。
綜上所述,通過檢測血清脂聯(lián)素及相關(guān)炎性因子,可以預(yù)測冠心病合并抑郁癥的發(fā)生,對其治療,預(yù)后及療效評判均具有重要意義。

[Abstract]Objective To analyze the serum adiponectin levels of patients with coronary heart disease combined with depression and its correlation with inflammatory factors.Methods 110 cases of patients with coronary heart disease confirmed by coronary angiography examination were selected and divided into the coronary heart disease combined with depression group with 52 cases and the coronary heart disease without depression group with 58 cases according to the Hamilton depression score,in addition,60 cases of normal people were selected as the control group,the levels of serum adiponectin (APN),IL-6,TNF-a and hs-CRP were measured.Results The serum IL-6(136±18.6)ng/L,TNF-a(15.6±9.5)ng/L and hs-CRP(4.6±3.1)mg/L in the coronary heart disease group were obviously higher than those in the control group(P<0.01), the serum APN(12.12±3.76)mg/L in the coronary heart disease group was obviously lower than that in the control group(P<0.01),the serum IL-6(166.2±21.6)ng/L,TNF-a(18.2±12.0)ng/L and hs-CRP(10.2±3.4)mg/L in the coronary heart disease combined with depression group were obviously higher than that in the coronary heart disease without depression group(P<0.01),the serum adiponectin in the coronary heart disease combined with depression group were obviously lower than that in the control group(P<0.01)and it also had an obvious negative correlation with the inflammatory factors IL-6,TNF-a and hs-CRP,(R values were respectively-0.560,-0.462 and-0.268,P<0.01).Conclusion The serum adiponectin level obviously decreases and the inflammatory factors IL-6,TNF-a and hs-CRP obviously increase in the coronary heart disease combined with depression group,these inflammatory factors have a certain inhabitation effect on adiponectin and then enhance the incidence of coronary heart disease and chances of coronary heart disease patients complicated by depression.
