生脉注射液联合去甲肾上腺素对多器官功能障碍综合征大鼠淋巴细胞凋亡及凋亡蛋白的影响

摘要

目的：研究生脉注射液联合去甲肾上腺素对多器官功能障碍综合征大鼠细胞免疫的影响。方法：选取40只健康雄性大鼠，通过应用酵母多糖腹腔注射致MODS模型，采用数字表法随机分为对照组、生脉注射液组、去甲肾上腺素组以及生脉注射液联合去甲肾上腺组，每组10只。用药后6、24、48 h检测血清中TNF－α、IL－1β、IL－12和IL－2的浓度，免疫组化检测大鼠脾脏caspase－3、caspase－8、caspase－9活性，流式细胞技术测定淋巴细胞凋亡情况及Th1／Th2。结果：①与对照组相比，生脉注射液组、去甲肾上腺组以及联合用药组，TNF、IL－1β浓度上升不是很明显，且随着治疗时间的延长，治疗各组TNF、IL－1β浓度逐渐下降，联合用药组TNF、IL－1β基本趋于正常；而IL－12、IL－2趋势则相反，治疗各组较对照组血清IL－12、IL－2浓度明显升高，联合用药组升高更加明显。②与对照组相比，生脉注射液组、去甲肾上腺素组以及联合用药组caspase－3、caspase－8、caspase－9表达均显著减少，且联合用药组凋亡蛋白的表达下降更明显，差异有统计学意义（ P＜0．05）。③生脉注射液组、去甲肾上腺素组以及联合用药组淋巴细胞凋亡的阳性细胞数比率较对照组明显减少，联合用药组淋巴细胞凋亡的阳性细胞数减少较生脉注射液组以及去甲肾上腺素组更明显；相比于对照组，生脉注射液组、去甲肾上腺素组以及联合用药组Th1／Th2比率明显增高，联合用药组增高更明显，差异有统计学意义（ P＜0．05）。结论：生脉注射液联合去甲肾上腺素对多器官功能障碍大鼠具有减轻炎症反应和改善免疫功能的作用。%Objective:To study the effect of the Shengmai injection combined with norepinephrine on cellular immunity in rats with multiple organ dysfunction syndrome .Methods:40 healthy male rats were randomly divided into the control group ,the Shengmai injection group ,the norepinephrine group and the Shengmai injection combined with norepinephrine group of 10 rats in each group after MODS rat model were established by intraperitoneal injection of zymosan .The plasma level of TNF-α, IL-1β, IL-12 and IL-2 were detected by ELISA ,and the protein expression of caspase-3,caspase-9 and caspase-8 in spleen were tested by IHC during 6 h,24 h,48 h.And the lymphocyte number of apoptosis and the ratio of Th 1/Th2 were tested by flow cytometry.Results: ① Compared with the control group, the plasma concentrations of TNF and IL-1βwere not significant increased in the Shengmai injection group , the norepinephrine group and the Shengmai injection combined with norepinephrine group ,as the extension of treatment time ,the plasma concentration of TNF and IL-1βwere significant lower in treatment groups than control group .While the plasma concentration of IL-12 and IL-2 were significantly increased in treatment groups , and the combined treatment group was more obvious .② Compared with control group,the protein expression of caspase-3,caspase-9 and caspase-8 in spleen were decreased in the Shengmai injection group , the norepinephrine group and the Shengmai injection combined with norepinephrine group ,and the combined treatment group was more obvious.③The lymphocyte number of positive apoptosis were significantly decreased , and the Th1/Th2 ratio were increased in the Shengmai injection group ,the norepinephrine group and the Shengmai injection combined with norepinephrine group ,and the combined treatment group was more obvious .Conclusion: The Shengmai injection combined with norepinephrine can reduce the inflammatory reaction and improve the immune function in the rat with multiple organ dysfunction .
