摘  要:目的 观察不稳定型心绞痛合并高血压病患者血浆和血小板P-选择素变化,并分析其意义.方法 选择心绞痛患者116例,其中单纯稳定型心绞痛患者36例为稳定型心绞痛组,单纯不稳定型心绞痛患者38例为不稳定型心绞痛组,不稳定型心绞痛合并高血压病组42例;选择与心绞痛患者性别、年龄相匹配的同期行冠状动脉造影健康者48例作为对照组.分别测定血浆和血小板内P-选择素含量以及血清总胆固醇、三酰甘油、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、超氧化物歧化酶、丙二醛含量,分析P-选择素与血脂、脂质过氧化物的相关性.结果 不稳定型心绞痛合并高血压病组患者血浆及血小板内P-选择素水平明显高于对照组、稳定型心绞痛组以及不稳定型心绞痛组[血浆P-选择素为(16.9±4.2) μg/L比(12.5±2.9)、(12.9±3.0)、(14.9±3.2) μg/L,均P<0.01;血小板P-选择素分别为(1.46±0.21)×104分子/血小板比(0.80±0.18)、(0.86±0.20)、(1.28 ±0.19) ×104分子/血小板,P<0.05或P<0.01];不稳定型心绞痛组血浆及血小板内P-选择素也明显高于对照组及稳定型心绞痛组(P <0.05或P<0.01);而稳定型心绞痛组血浆及血小板内P-选择素含量与对照组差异无统计学意义(P>0.05).对照组总胆固醇、三酰甘油、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、丙二醛、超氧化物歧化酶分别为(4.98±0.76) mmol/L、(1.34±0.36) mmol/L、(1.23±0.40) mmol/L、(3.19±0.56) mmol/L、(0.15±0.05) nmol/L、(83±22) kIU/L;稳定型心绞痛组分别为(5.41±0.76) mmol/L、(1.59±0.38) mmol/L、(1.18±0.44) mmol/L、(3.64±0.54) mmol/L、(0.22±0.06) nmol/L、(70±20) kIU/L;单纯不稳定型心绞痛组分别为(5.46±0.82) mmol/L、(1.60±0.37) mmol/L、(1.14±0.45) mmol/L、(3.69±0.58) mmol/L、(0.29±0.06) nmol/L、(59±20) kIObjective To study the changes of P-selectin in unstable angina pectoris (UAP) patients with hypertension(HBP).Methods One hundred and sixteen patients with angina pectoris were as experiment group,including 36 patients with stable angina pectoris(SAP group),38 patients with UAP(UAP group) and 42 UAP patients with HBP(UAP and HBP group).48 normal persons were as control group.Levels of plasma and platelet P-selectin,blood lipid [total cholesterol (TC),triacylglycerol (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol(HDL-C)],malonyldiadehyde (MDA) and superoxide dismutase(SOD) were analyzed in all cases.Results The levels of plasma and platelet P-selectin in UAP and HBP group were markedly higher than those in control group and SAP group as well as UAP group [plasma was (16.9 ± 4.2) μg/L vs (12.5 ± 2.9),(12.9 ± 3.0),(14.9 ± 3.2) μg/L,all P 〈 0.01 ; platelet P-selectin was (1.46 ± 0.21) × 104/BPC vs(0.80 ±0.18),(0.86 ±0.20),(1.28 ±0.19) × 104/BPC,P 〈0.05 or P 〈0.01].The levels of those parameters in UAP group were markedly higher than those in control group as well as SAP group (P 〈 0.01).Compared with those in the normal cases,the levels of plasma and platelet P-selectin were not significantly changed in SAP group(P 〉 0.05).TC,TG,HDL-C,LDL-C,MDA,SOD in control group were (4.98 ± 0.76) mmol/L,(1.34 ±0.36) mmol/L,(1.23 ± 0.40) mmol/L,(3.19 ± 0.56) mmol/L,(0.15 ± 0.05) nmol/L,(89 ± 29) kIU/L,respectively; those in SAP group were (5.41 ± 0.76) mmol/L,(1.59 ± 0.38) mmol/L,(1.18 ± 0.44) mmol/L,(3.64 ±0.54) mmol/L,(0.22 ± 0.06) nmol/L,(84 ± 22) kIU/L,respectively; Those in UAP group were (5.46 ± 0.82) mmol/L,(1.60 ± 0.37) mmol/L,(1.14 ± 0.45) mmol/L,(3.69 ± 0.58) mmol/L,(0.29 ± 0.06) nmol/L,(70 ±20) kIU/L,respectively;Those in UAP and HBP group were(5.51 ±0.86) mmol/L,(1.60
