摘要:

目的 探讨葡萄糖调节蛋白78(GRP78)在哮喘炎症及病情监测中的作用,分析GRP78与Th1、Th2、Th17细胞因子及肺功能指标FEV1%、FEV1/FVC%的相关性。 方法 纳入115例哮喘患者(其中轻度哮喘57例、中度哮喘47例和重度哮喘11例)和42例健康对照。通过ELISA检测血清GRP78、IL-4、IL-13、IL-17和IFN-γ水平,同时收集肺功能指标FEV1%、FEV1/FVC%进行综合分析。 结果 血清GRP78在哮喘患者组的水平显著高于正常对照组(P < 0.01),且水平随着病情严重程度增加而升高,轻、中、重度哮喘组GRP78水平分别为(23.42 ± 0.12)ng/mL、(28.01 ± 0.03)ng/mL 和(33.33 ± 0.14)ng/mL,均高于对照组的(16.38 ± 0.11)ng/mL(P < 0.05);哮喘患者中血清IL-4、IL-13、IL-17水平[分别为(2 754.07 ± 7.32)pg/mL, (2 490.72 ± 41.32)pg/mL, (7 080.38 ± 546.32)pg/mL]显著高于正常对照组[分别为(1 493.44 ± 344.32)pg/mL,(1 280.18 ± 20.43)pg/mL,(3 668.92 ± 321.51)pg/mL](P < 0.01),而IFN-γ的水平[(652.90 ± 42.67) pg/mL]低于正常对照组[(110 1.3 ± 111.42) pg/mL](P < 0.01);Pearson相关分析显示,GRP78与IL-13、IL-17水平呈正相关(IL-13:r = 0.34, P < 0.05;IL-17:r = 0.26, P < 0.05),与IFN-γ水平、FEV1%、FEV1/FVC%呈负相关(IFN-γ:r = -0.31, P < 0.05;FEV1%::r = -0.21, P < 0.05;FEV1/FVC%:r = -0.32, P < 0.05)。 结论 哮喘患者中血清GRP78水平显著升高,且随着病情严重程度的加重而升高;血清GRP78有望成为评估哮喘病情和预后的新型生物标志物。

Abstract:

Objective To assess the potential of GRP78 as a clinical biomarker in asthma by evaluating its relationship with key inflammatory cytokines and pulmonary function. Methods A total of 115 asthma patients (including 57 with mild, 47 with moderate, and 11 with severe asthma) and 42 healthy controls were enrolled. Serum levels of GRP78, IL-4, IL-13, IL-17, and IFN-γ were measured using ELISA. Pulmonary function parameters, including FEV1% and FEV1/FVC%, were also collected for comprehensive analysis. Results The level of serum GRP78 in the asthma patient group was significantly higher than that in the normal control group (P < 0.01), and it increased with the severity of the disease. The levels of GRP78 in the mild, moderate and severe asthma groups were (23.42 ± 0.12) ng/mL, (28.01 ± 0.03) ng/mL and (33.33 ± 0.14) ng/mL respectively, all of which were higher than that in the control group (16.38 ± 0.11) ng/mL (P < 0.05). The levels of serum IL-4, IL-13 and IL-17 in asthma patients [(2 754.07 ± 7.32) pg/mL, (2 490.72 ± 41.32) pg/mL, (7 080.38 ± 546.32) pg/mL respectively] were significantly higher than those in the normal control group [(1 493.44 ± 344.32) pg/mL, (1 280.18 ± 20.43) pg/mL, (3 668.92 ± 321.51) pg/mL respectively] (P < 0.01), while the level of IFN-γ [(652.90 ± 42.67) pg/mL] was lower than that in the control group [(1 101.3 ± 111.42) pg/mL] (P < 0.01). Pearson correlation analysis showed that GRP78 was positively correlated with the levels of IL-13 and IL-17 (IL-13: r = 0.34, P < 0.05; IL-17: r = 0.26, P < 0.05), and negatively correlated with the levels of IFN-γ, FEV1% and FEV1/FVC% (IFN-γ: r = -0.31, P < 0.05; FEV1%: r = -0.21, P < 0.05; FEV1/FVC%: r = -0.32, P < 0.05). Conclusions Serum GRP78 is elevated in asthma and correlates with disease severity, Th2/Th17 inflammation, and impaired lung function. These findings support its potential utility as a clinically relevant biomarker for asthma evaluation and monitoring.
