  • 摘要:   目的   探讨糖尿病周围神经病变(DPN)中神经鞘胚素蛋白表达的变化及人脂肪干细胞(ADSC)外泌体对神经鞘胚素蛋白表达变化的调节作用。   方法   该研究为前瞻性观察性临床研究联合实验研究。将空军军医大学第一附属医院(以下简称本院)2022年5月—2023年10月收治的13例符合入选标准的DPN患者(男9例、女4例,年龄32~68岁)作为DPN组,将本院该段时间收治的5例符合入选标准的非糖尿病患者(男4例、女1例,年龄29~61岁)作为对照组。采集2组患者清创或截肢后弃用组织中的趾神经或腓肠神经组织,行苏木精-伊红染色后观察神经组织的病理学变化,行免疫荧光染色后观察神经组织中S100β、神经鞘胚素的蛋白表达并对神经鞘胚素蛋白表达进行定量,分别采用蛋白质印迹法和实时荧光定量反转录PCR法检测神经鞘胚素的蛋白和mRNA表达(DPN组样本数均为13,对照组样本数均为5)。取12只雄性3~5 d龄C57BL/6小鼠,提取施万细胞,并将细胞分为常规培养组(常规培养)、单纯高糖组(仅用高浓度葡萄糖溶液培养)、高糖+外泌体组(用高浓度葡萄糖溶液和提取的人ADSC外泌体培养)。培养24 h后,采用细胞计数试剂盒8检测细胞增殖活力(样本数为6);培养48 h后,采用蛋白质印迹法检测神经鞘胚素的蛋白表达(样本数为3)。   结果   相较于对照组,DPN组患者神经组织中神经支持细胞减少、炎症细胞增多,具有典型的神经损伤表现。免疫荧光染色检测显示,相较于对照组,DPN组患者神经组织中细胞核更多,S100β的蛋白表达更少;DPN组患者神经组织中神经鞘胚素蛋白表达为71±31,明显低于对照组的1 729±62( t=76.92, P<0.05)。蛋白质印迹法检测显示,DPN组患者神经组织中的神经鞘胚素蛋白表达为0.74±0.08,明显低于对照组的0.97±0.06( t=5.49, P<0.05)。DPN组患者神经组织中神经鞘胚素的mRNA表达明显低于对照组( t=7.65, P<0.05)。培养24 h后,与常规培养组比较,单纯高糖组和高糖+外泌体组施万细胞增殖活力均明显降低( P<0.05);与单纯高糖组比较,高糖+外泌体组施万细胞增殖活力明显升高( P<0.05)。培养48 h后,与常规培养组比较,单纯高糖组、高糖+外泌体组施万细胞神经鞘胚素蛋白表达均明显降低( P<0.05);与单纯高糖组比较,高糖+外泌体组施万细胞神经鞘胚素蛋白表达明显升高( P<0.05)。   结论   DPN患者神经组织中神经鞘胚素的蛋白表达较正常神经组织降低,这可能与高糖降低了施万细胞增殖活力相关;人ADSC外泌体可能通过提高神经鞘胚素蛋白表达,改善施万细胞增殖活力,进而延缓DPN的进展。
