文题释义:
人羊膜间充质干细胞:
羊膜位于胎盘的最内层,主要由来源于外胚层的上皮细胞和来源于中胚层的间充质细胞构成。其不含血管,细胞成分相对简单,在胎儿娩出后即成为“废弃物”。人羊膜间充质干细胞有着来源丰富、无需有创操作、取材几乎不受限制、分离培养方法简便、有向3个胚层来源的组织细胞分化的潜能、免疫原性低等多种优点,可能成为一种更加理想的间充质干细胞临床研究及应用的来源。
急性肺损伤:是各种直接和间接致伤因素导致的肺泡上皮细胞及毛细血管内皮细胞损伤,造成弥漫性肺间质及肺泡水肿,导致的急性低氧性呼吸功能不全。以肺容积减少、肺顺应性降低、通气/血流比例失调为病理生理特征,临床上表现为进行性低氧血症和呼吸窘迫,肺部影像学上表现为非均一性的渗出性病变,其发展至严重阶段(氧合指数< 200)被称为急性呼吸窘迫综合征。

 

摘要
背景:
随着细胞技术的提高,使得干细胞移植研究延伸到包括输血相关急性肺损伤在内的各个领域。
目的:探讨痰热清注射液联合人羊膜间充质干细胞移植对输血相关急性肺损伤小鼠的保护作用及机制。
方法:选取80只BALB/C雄性小鼠,随机分为对照组、模型组、痰热清注射液组、人羊膜间充质干细胞移植组及联合治疗组。除对照组外,其他4组制备输血相关急性肺损伤模型。经尾静脉注入痰热清注射液和人羊膜间充质干细胞悬液干预24 h后,镜下观察各组小鼠肺组织病理形态,计算肺组织湿干质量比,ELISA测定各组小鼠支气管肺泡灌洗液中白细胞介素10、白细胞介素1β、肿瘤坏死因子α水平,RT- PCR、Western blot检测肺损伤小鼠肺组织KGF-1基因和蛋白表达,TUNEL法检测肺组织细胞凋亡情况。  
结果与结论:①模型组小鼠肺组织出现肺泡间隔增厚、肺泡内纤维蛋白浸润、肺泡内出血、支气管壁增厚等病理变化,肺组织湿干质量比增高,人羊膜间充质干细胞移植组和痰热清注射液组以上病理变化较模型组略轻,肺组织湿干质量比低于模型组(P < 0.05),联合治疗组肺组织湿干质量比明显低于模型组(P < 0.01);②人羊膜间充质干细胞移植组和痰热清注射液组小鼠肺泡灌洗液中白细胞介素10、白细胞介素1β、肿瘤坏死因子α水平均低于模型组(P < 0.05);联合治疗组上述各因子水平明显低于模型组(P < 0.01),仍高于正常对照组(P < 0.05);③联合治疗组KGF-1基因和蛋白的表达高于人羊膜间充质干细胞移植组和痰热清注射液组(P < 0.05),人羊膜间充质干细胞移植组和痰热清注射液组高于模型组(P < 0.05);④联合治疗组凋亡细胞数低于人羊膜间充质干细胞移植组和痰热清注射液组,人羊膜间充质干细胞移植组和痰热清注射液组低于模型组;⑤结果表明,痰热清注射液联合人羊膜间充质干细胞移植能提高输血相关急性肺损伤小鼠肺组织中KGF-1的表达,减轻肺部炎症反应及组织病理学损伤程度,减少肺组织细胞凋亡,对肺损伤具有保护作用。

Abstract:

BACKGROUND: With the improvement of cellular technology, stem cell transplantation has been involved in various diseases, such as transfusion-related acute lung injury (TRALI).

OBJECTIVE: To investigate the protective effect of Tanreqing injection combined with human amniotic mesenchymal stem cells (hAMSCs) transplantation in a mouse model of TRALI. 
METHODS: A total of 80 BALB/C male mice were divided into control group, model group, Tanreqing injection group, hAMSCs transplantation group and combined group (Tanreqing injection+hAMSCs transplantation group). Animal models of TRALI were made in all groups except the control group. Mouse lung tissue pathology and wet/dry ratio were observed and calculated 24 hours after treatment. ELISA was used to measure interleukin-10, interleukin-1β, and tumor necrosis factor-α levels in bronchoalveolar lavage fluid. Expression of keratinocyte growth factor-1 mRNA and protein was detected by RT-PCR and western blot, respectively. Apoptosis in the lung tissue was detected by TUNEL method.  
RESULTS AND CONCLUSION: (1) Thickened alveolar septum, alveolar fibrin infiltration, alveolar hemorrhage, thickened bronchial wall, and increased lung wet/dry ratio were observed in the model group, and these pathological changes were slightly milder in the Tanreqing injection group and hAMSCs transplantation group. Compared with the model group, the lung wet/dry ratio was significantly lower in the Tanreqing injection group and hAMSCs transplantation group (P < 0.05), and very significantly lower in the combined group (P < 0.01). (2) Compared with the model group, the levels of interleukin-10, interleukin-1β, and tumor necrosis factor-α in the bronchoalveolar lavage fluid were significantly lower in the Tanreqing injection group and hAMSCs transplantation group (P < 0.05), and very significantly lower in the combined group (P < 0.01), but these levels were still higher in the combined group than the control group (P < 0.05). (3) The expression levels of keratinocyte growth factor-1 mRNA and protein were ranked as follows: combined group > Tanreqing injection group and hAMSCs transplantation group > model group, and there were significant differences between them (P < 0.05). (4) The apoptotic index was ranked as follows: combined group < Tanreqing injection group and hAMSCs transplantation group < model group. To conclude, Tanreqing injection combined with hAMSCs transplantation can improve expression of keratinocyte growth factor-1 in the lung tissue of TRALI mice, reduce degree of lung inflammatory reaction and pathologic injury, and reduce the apoptosis in the lung tissue, which plays a protective role against lung injury in mice.
