Syndecan-1在急性百草枯中毒肺损伤的表达意义

Significance of Syndecan-1 expression in acute paraquat poisoning lung injury

目的:探讨多配体蛋白聚糖-1(Syndecan-1)在急性百草枯中毒(acute paraquat poisoning, APP)肺损伤患者中的表达意义。方法:选取2018年1月-2020年12月衡水市第二人民医院收治的APP患者136例,根据患者住院期间生存情况分为死亡组87例和存活组49例。分别在入院后24、72 h,检测C反应蛋白(CRP)、白介素-6(IL-6)、白介素-10(IL-10)、肿瘤坏死因子-α(TNF-α);同时采用ELISA法检测Syndecan-1、透明质酸(hyaluronic acid, HA)、硫酸类肝素(heparan sulfate, HS)。入院后72 h用Murray肺损伤评分系统对肺损伤程度进行评估。结果:生存组和死亡组患者性别、年龄、体质量比较,差异无统计学意义(P>0.05)。死亡组服毒剂量、就诊时间与生存组比较,差异有统计学意义(P<0.05)。入院后24 h,生存组和死亡组CRP、IL-6、IL-10、TNF-α比较,差异无统计学意义(P>0.05)。死亡组HA、Syndecan-1、HS高于生存组,差异有统计学意义(P<0.05)。入院后72 h,死亡组CRP、IL-6、IL-10、TNF-α、HA、Syndecan-1、HS明显高于生存组,差异有统计学意义(P<0.05)。生存组和死亡组入院后72 h的CRP、IL-6、IL-10、TNF-α、HA、Syndecan-1、HS均高于入院后24 h,差异有统计学意义(P<0.05)。相关性分析:入院后72 h, APP患者多糖包被降解产物HA、Syndecan-1、HS与Murray肺损伤评分之间呈正相关(r=0.667,P=0.013;r=0.732,P=0.004;r=0.661,P=0.014)。ROC曲线显示,入院24 h Syndecan-1对肺损伤患者预后有一定预测价值;入院72 h Syndecan-1对肺损伤患者预后的预测价值最大。结论:Syndecan-1在APP患者急性肺损伤早期升高,与Murray肺损伤评分有一定相关性,对评估APP肺损伤有临床预测价值。

Objective:To investigate the significance of Syndecan-1(SDC-1)expression in patients with acute paraquat poisoning(APP)lung injury.Methods:A total of 136 patients with APP admitted to our hospital from January 2018 to December 2020 were selected,and the patients were divided into 87 cases in the death group and 49 cases in the survival group according to their during hospitalization.C-reactive protein(CRP),interleukin-6(IL-6),interleukin-10(IL-10),and tumor necrosis factor-α(TNF-α)were detected at 24 h and 72 h after admission,respectively;hyaluronic acid(HA),multiligand proteoglycan-1(SDC-1),and heparan sulfate(HS)were also de-tected by ELISA.The degree of lung injury was assessed by the Murray Lung Injury Scoring System 72 h after admission.Results:There was no statistically significant difference in gender,age,and body mass of patients in the survival and death groups(P>0.05).There was a statistically significant difference in the dose of toxicity and the time of consultation in the death group compared with the survival group(P<o.05).There was no statistical difference in CRP,IL-6,IL-10,and TNF-αbetween the survival and death groups at 24 h after admission(P>O.05).HA,SDC-1,and HS were higher in the death group than in the survival group,and the differences were statistically significant(P<0.05).At 72 h after admission,CRP,IL-6,IL-10,TNF-α,HA,SDC-1,and HS were significantly higher in the death group than in the survival group,and the difference was statistically signifi-cant(P<o.05).In both the survival and death groups,CRP,IL-6,IL-1O,TNF-α,HA,SDC-1,and HS were higher at 72 h after admission than at 24 h after admission,and the difference was statistically significant(P<O.05).Correlation analysis:72 h after admission,there was a positive correlation between polysaccharide-encap-sulated degradation products HA,SDC-1,HS and Murray's lung injury score in APP patients(r=0.667,P=0.013;r=0.732,P=0.004;r=0.661,P=0.014).OC showed that Syndecan-1 at 24 h after admission had lung injury patients;Syndecan-l at 72 hours of admission had the greatest predictive value for prognosis of lung injury patients.Conclusion:Syndecan-l is elevated early in acute lung injury in APP patients and is of good clinical value in assessing the condition and prognosis.
