文题释义:
内毒素:
化学成分为脂多糖,位于革兰阴性细菌细胞壁上,其毒性成分主要为类脂质A,只有当细菌死亡溶解或用人工方法破坏菌细胞后才释放。当把内毒素大量注入血液中,超过机体各自卫系统的清除能力,则可导致不同程度的内毒素血症,同时也可导致致死性感染性休克、多器官功能衰竭、弥漫性血管内凝血等,病死率极高。症状和体征主要有发热、白细胞数减少、弥漫性血管内凝血、心力衰竭、肾功能减退、肝脏损伤、缺氧及酸中毒等。
全身炎症反应综合征:是因感染或非感染病因作用于机体而引起的机体失控的自我持续放大和自我破坏的全身性炎症反应。它是机体修复和生存而出现过度应激反应的一种临床过程。当机体受到外源性损伤或感染毒性物质的打击时,可触发初期炎症反应,同时机体产生内源性免疫炎性因子而形成“瀑布效应”,严重者可导致多器官功能障碍综合征。

 

摘要

背景:多器官功能障碍综合征为当今临床治疗的一大难题,骨髓间充质干细胞移植为其提供了一个新的治疗研究方向。
目的:观察骨髓间充质干细胞移植治疗多器官功能障碍综合征的疗效。
方法:按1 mg/kg剂量股静脉注射内毒素建立大鼠多器官功能障碍综合征模型,将存活的大鼠随机分为治疗组和模型组,治疗组大鼠尾静脉注射500 μL(5×106)第3代骨髓间充质干细胞,对照组尾静脉注射等体积的生理盐水;治疗5 d后行血常规、血生化、凝血功能检测,取血后处死大鼠取肝脏、肾脏、心脏、脾脏进行苏木精-伊红染色病理学观察。
结果与结论:①移植治疗1周后,与模型组相比,治疗组肝功能、凝血功能各项指标明显得到改善(P < 0.05),白细胞计数更接近正常水平(P < 0.05);②模型组心、肝、脾、肾脏均出现不同程度的炎症性病变和坏死,治疗组炎性浸润和坏死性病变明显减轻;③结果提示,骨髓间充质干细胞对多器官功能障碍综合征模型大鼠具有明显的治疗作用。

Abstract:

BACKGROUND: Clinical treatment of multiple organ dysfunction syndrome has been a big problem today, while the treatment of bone marrow mesenchymal stem cells may provide a new research direction.

OBJECTIVE: To investigate the therapeutic effects of bone marrow mesenchymal stem cells transplanted into multiple organ dysfunction syndrome models.
METHODS: According to body weight of rats, endotoxin in the 1 mg/kg dose was injected into the femoral vein to build the multiple organ dysfunction syndrome models in rats, and the surviving rats were randomly divided into treatment and control groups. Then the rats in the treatment group were injected intravenously third-generation bone marrow mesenchymal stem cells (5×106), while rats in the control group injected intravenously with an equal volume of saline. After 5 days of treatment, the blood routine examination, blood biochemistry and coagulation tests were conducted, and then the liver, kidney, heart, and spleen of rats were captured to observed pathological changes through the hematoxylin-eosin staining.

RESULTS AND CONCLUSION: One week after cell transplantation, liver function and biochemical indicators were improved significantly in the treatment group compared with the control group (P < 0.05), and the white blood cell count in the treatment group was closer to normal levels (P < 0.05). Hematoxylin-eosin staining results showed that in the multiple organ dysfunction syndrome rats appeared to have different degrees of inflammatory lesions and necrosis in the heart, liver, spleen, and kidneys, while inflammatory infiltration and necrotic lesions decreased significantly in the treatment group compared with the control group. To conclude, bone marrow mesenchymal stem cells exert remarkable therapeutic effects on multiple organ dysfunction syndrome.
