葛根芩连汤:
为表里双解剂,具有解表清里之功效,主治协热下利,身热下利,胸脘烦热,口干作渴,喘而汗出,舌红苔黄,脉数或促。临床常用于治疗急性肠炎、细菌性痢疾、肠伤寒、胃肠型感冒等属表证未解、里热甚者。
糖尿病视网膜病变:糖尿病患者主要是胰岛素激素及细胞代谢异常,引起眼组织、神经及血管微循环改变,造成眼的营养和视功能的损坏。微血管是指介于微小动脉和微小静脉之间,管腔小于100-150 µm的微小血管及毛细血管网,是组织和血液进行物质交换的场所。由于糖尿病患者血液成分的改变,而引起血管内皮细胞功能异常,使血-视网膜屏障受损。视网膜毛细血管内皮细胞色素上皮细胞间的联合被破坏,造成小血管的渗漏。

 

摘要
背景:
研究发现人羊膜间充质干细胞可以向胰岛素分泌细胞分化,还具有免疫调节作用。临床证实葛根芩连汤有明确降低血糖的作用。
目的:探讨葛根芩连汤联合人羊膜间充质干细胞移植对糖尿病大鼠早期视网膜病变形态学、相关血清学指标及血管内皮生长因子基因表达的影响。
方法:以腹腔注射链脲佐菌素方式制作糖尿病模型,将造模成功的42只Wistar大鼠随机分为模型组、人羊膜间充质干细胞移植组和联合组(人羊膜间充质干细胞移植+葛根芩连汤),移植后4周测定糖尿病大鼠血糖、血清胰岛素水平;移植后4周苏木精-伊红染色镜下观察糖尿病大鼠视网膜的病理形态;免疫组织化学方法检测视网膜组织CD45的表达水平;RT-PCR法检测视网膜血管内皮生长因子mRNA的表达。
结果与结论:①与模型组比较,人羊膜间充质干细胞移植组和联合组大鼠血糖降低,血清胰岛素浓度增加,联合组改善更为明显,组间比较差异有显著性意义(P < 0.05);②模型组大鼠有明显视网膜水肿、层次紊乱,细胞排列不规则;与模型组比较,人羊膜间充质干细胞移植组大鼠视网膜病变相对轻微,联合组视网膜病变明显好转;③模型组视网膜CD45的表达明显增加,人羊膜间充质干细胞移植组CD45的表达量明显小于模型组(P < 0.05),但大于联合组(P < 0.05);④联合组和人羊膜间充质干细胞移植组血管内皮生长因子mRNA表达低于模型组,联合组降低幅度更大,差异有显著性意义(P < 0.05);⑤结果表明,葛根芩连汤联合人羊膜间充质干细胞移植可能通过抑制CD45和血管内皮生长因子在视网膜组织表达,从而改善糖尿病视网膜病损严重程度。

Abstract:

BACKGROUND: Human amniotic mesenchymal stem cells have the potential to differentiate into insulin-secreting cells and have immunomodulatory effects. Additionally, it has been clinically proved that Gegen Qin Lian Tang can lower blood sugar.
OBJECTIVE: To investigate the effects of Gegen Qin Lian Tang combined with human amniotic mesenchymal stem cell transplantation on rat early diabetic retinopathy, by detecting pathological changes, levels of blood indicators and expressions of vascular endothelial growth factor in retinal tissues.
METHODS: By intraperitoneal injection of streptozotocin, 42 Wistar rat models with diabetes mellitus were prepared and then randomly divided into model group, human amniotic mesenchymal stem cell transplantation group (cell transplantation group) and combination of human amniotic mesenchymal stem cells and Gegen Qin Lian Tang group (combination group). At 4 weeks after transplantation, levels of blood sugar and serum insulin in diabetic rats were detected; pathological changes of the retina in diabetic rats were observed by hematoxylin-eosin staining. Besides, expressions of CD45 and vascular endothelial growth factor mRNA were detected using immunohistochemistry staining and RT-PCR technology, respectively.
RESULTS AND CONCLUSION: Compared with the model group, the levels of blood glucose and serum insulin in both cell transplantation and combination groups were significantly decreased and increased, respectively, and these changes were even more significant in the combination group (P < 0.05). In the model group, the retinal edema could be found, accompanied by structural disorder and irregular cell arrangement, while these retinal lesions were relatively milder in the cell transplantation group and significantly improved in the combination group. In addition, the CD45 expression and in the retina was highest in the model group subsequently followed by the cell transplantation group (P < 0.05) and lowest in the combination group (P < 0.05). Furthermore, compared with the model group, the expression of vascular endothelial growth factor mRNA was also significantly lower in the other two groups, especially in the combination group (P < 0.05). These data show that Gegen Qin Lian Tang combined with human amniotic mesenchymal stem cell transplantation improves the severity of diabetic retinopathy by inhibiting expressions of CD45 and vascular endothelial growth factor in the retinal tissues.
