血清高迁移率族蛋白1水平与急性有机磷农药中毒的相关性探讨

目的 探讨急性有机磷农药中毒(AOPP)与血清高迁移率族蛋白1(HMGBl)的相关性.方法 采用蛋白质免疫印迹检测116例AOPP患者及40例健康体检者(健康对照组)HMGB1水平,按病情严重程度将AOPP患者分为轻度组(40例)、中度组(39例)、重度组(37例),再将重度组分为多器官功能不全综合征(MODS)组(20例)和非MODS组(17例),比较各组血清胆碱酯酶(CHE)、HMGB1水平.结果 AOPP患者中重度组血清HMGB1吸光度值为(2.91±0.12),显著高于中度组(2.15±0.17)、轻度组(1.16±0.29)和健康对照组(0.84±0.30),差异有统计学意义(P＜0.01),中度组显著高于轻度组和健康对照组(P＜0.01),轻度组显著高于健康对照组(P＜0.05).重度组中,MODS组血清HMGB1吸光度值显著高于非MODS组(P＜0.01),而CHE两组比较差异无统计学意义(P＞0.05).结论 AOPP患者病情严重程度与血清HMGB1水平明显相关,血清HMGB1水平可作为评价AOPP患者病情严重程度的指标之一.

Abstract：

Objective To study the correlation between the serum high mobility group protein B1 (HMGB1)and the acute organophosphorus pesticide poisoning(AOPP). Methods The serum HMGB1 levels of the 116 patients with AOPP(AOPP group)and 40 healthy adults(control group)were detected by immunoblotting method. According to illness severity, AOPP group was divided into mild group(40 cases),moderate group(39 cases)and severe group(37 cases), and severe group was divided into multiorgan dysfunction syndrome(MODS)group(20 cases)and no MODS group(17 cases). The serum levels of CHE,HMGB1 were compared. Results The absorbance of HMGB1 in severe group(2.91±0.12)was significantly higher than that in moderate group(2.15±0.17), mild group(1.16 ± 0.29)and control group (0.84±0.30)(P＜0.01).The absorbance of HMGB1 in moderate group was significantly higher than that in mild group and control group(P＜0.01). The absorbance of HMGB1 in mild group was significantly higher than that in control group(P＜0.05). The absorbance of HMGB1 in MODS group was significantly higher than that in no MODS group(P＜0.01),but the absorbance of CHE had no significant difference between two groups(P＞0.05). Conclusions The degree of AOPP has notable correlation with the level of serum HMGB1. The level of serum HMGB1 is an useful index for evaluating the degree of AOPP.
