文题释义:
白细胞介素:由多种细胞产生并作用于多种细胞的一类细胞因子。目前至少发现了38个白细胞介素,其在免疫细胞的成熟、活化、增殖和免疫调节等一系列过程中均发挥重要作用。根据细胞因子的结构同源性可将其分为几个蛋白质家族,如白细胞介素1家族、白细胞介素6家族、白细胞介素10家族和造血因子家族等。
中性粒细胞:在瑞氏染色血涂片中,胞质呈无色或极浅的淡红色,有许多弥散分布的细小的(0.2-0.4 μm)浅红或浅紫色的特有颗粒。细胞核呈杆状或2-5分叶状,叶与叶间有细丝相连。中性粒细胞具有趋化作用、吞噬作用和杀菌作用。中性粒细胞来源于骨髓,具有分叶形或杆状的核,胞浆内含有大量既不嗜碱也不嗜酸的中性细颗粒。这些颗粒多是溶酶体,内含髓过氧化酶、溶菌酶、碱性磷酸酶和酸性水解酶等丰富的酶类,与细胞的吞噬和消化功能有关。

摘要
背景:
研究发现粒细胞集落刺激因子可以用于治疗粒细胞减少症,关于粒细胞集落刺激因子治疗脓毒症的研究不多。
目的:探讨重组人粒细胞巨噬细胞集落刺激因子对脓毒症小鼠的治疗作用。
方法:采用腹腔内注射脂多糖的方法建立脓毒症小鼠动物模型,建模后6,30 h皮下注射重组人粒细胞巨噬细胞集落刺激因子,观察小鼠的肺组织病理变化、外周血中性粒细胞CD64表达以及血清肿瘤坏死因子α、白细胞介素10水平。
结果与结论:①治疗后小鼠支气管上皮尚完整,间质轻度增生,见少量中性粒细胞浸润;②治疗后1,3,7 d治疗组小鼠外周血中性粒细胞CD64的表达和血清白细胞介素10水平显著高于模型组和正常对照组(P < 0.05);③治疗后1,3,7 d治疗组小鼠血清肿瘤坏死因子α水平明显高于正常对照组(P < 0.05),但低于模型组(P < 0.05);④结果表明,重组人粒细胞巨噬细胞集落刺激因子具有增强脓毒症小鼠中性粒细胞功能和抗炎作用。

Abstract:

BACKGROUND: Granulocyte colony-stimulating factor has been shown to be used for the treatment of granulocytopenia, but its effect on sepsis is little reported.
OBJECTIVE: To explore the treatment outcomes of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) for sepsis mice.
METHODS: A sepsis mouse model was established by intraperitoneal injection of lipopolysaccharide, and then given subcutaneous injection of rhGM-CSF at 6 and 30 hours after modeling. The morphological change of mouse lung tissue, CD64 expression in peripheral neutrophils, and serum levels of tumor necrosis factor-α and interleukin-10 were ovserved, respectively.
RESULTS AND CONCLUISON: (1) Complete bronchial epithelial, mild stromal hyperplasia, and a few neutrophil infiltration were found after rhGM-CSF treatment. (2) CD64 expression in peripheral neutrophils, and serum level of interleukin-10 in the treatment group were significantly higher than those in the model and control groups at 1, 3 and 7 days after treatment (P < 0.05). The serum level of tumor necrosis factor-α in the treatment group was significantly higher than that in the control group, but lower than that in the model group after 1, 3 and 7 days of treatment (P < 0.05). (4) These results show that rhGM-CSF can enhance neutrophil function and the anti-inflammatory effects in sepsis mice.
