摘　　要：目的:通过检测原发性高血压(EH)左室肥厚(LVH)患者外周血中白介素-33(IL-33)和可溶性ST2(sST2)水平,进而探讨其与EH并发LVH的相关性。方法:纳入蚌埠医学院第一附属医院心血管内科门诊就诊的EH患者220例为实验组,根据左心室质量指数(LVMI)将其分为无左室肥厚组(NLVH,n=108)和左室肥厚组(LVH,n=112)。ELISA法检测受试者血清中IL-33、sST2水平,Western blot检测NLVH组及LVH组(各60例)外周血淋巴细胞中IL-33的表达水平,应用Pearson分析其与LVMI关系,进而研究IL-33、sST2与原发性高血压左室肥厚的关系。结果:与NLVH组相比,LVH组患者血清IL-33、sST2活性水平显著增高,且WB显示:LVH组的IL-33蛋白表达水平(1.07±0.08)高于NLVH组(0.63±0.05)(P<0.05);运用Pearson相关分析发现IL-33、sST2与LVMI之间存在正相关。结论:高血压左心室肥厚患者血清IL-33、sST2水平以及外周血淋巴细胞IL-33蛋白表达水平明显升高,原发性高血压左室肥厚发生、发展可能与IL-33、sST2有关。Objective:To detect the levels of interleukin-33(IL-33)and soluble ST2(sST2)in peripheral blood of patients with essential hypertensive left ventricular hypertrophy,and to discusstheir correlation with patients with essential hypertensive left ventricular hypertrophy was further discussed.Methods:A total of 220 patients with essential hypertension treated in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Bengbu Medical College were enrolled as the experimental group.According to left ventricular mass index(LVMI),patients with essential hypertension were divided into the non-left ventricular hypertrophy group(NLVH,n=108 cases)and the left ventricular hypertrophy group(LVH,n=112 cases).We used ELISA to detect the serum levels of IL-33 and sST2,the expression levels of IL-33 in peripheral blood lymphocytes of the NLVH group and the LVH group(60 cases each)were detected by Western blot,and the relationship between IL-33 and LVMI,a marker of left ventricular hypertrophic condition,was analyzed by Pearson.The relationship between IL-33,sST2 and left ventricular hypertrophy in essential hypertension was studied.Results:Compared with the NLVH group,the expression levels of IL-33 and sST2 in the LVH group were significantly increased.The results of Western blot showed that the expression level of IL-33 in the LVH group(1.07±0.08)was higher than that in the NLVH group(0.63±0.05)(P<0.05).Pearson correlation analysis showed that IL-33 was positively correlated with LVMI,sST2 was positively correlated with LVMI.Conclusion:The levels of IL-33 and sST2 in serum and the expression levels of IL-33 protein in peripheral blood lymphocytes are significantly increased in patients with hypertensive left ventricular hypertrophy,and the occurrence and development of essential hypertensive left ventricular hypertrophy may be related to IL-33 and sST2.
