文题释义:

糖尿病肾病:受到糖尿病高血糖、高血压及高血脂的影响,患者的肾小球微循环滤过压会出现异常上升,促进糖尿病肾病发生和发展,早期表现为蛋白尿、浮肿,晚期发生肾功能衰竭。
骨髓间充质干细胞治疗糖尿病肾病:①直接分化为受损伤的组织细胞。骨髓间充质干细胞可以再生为肾脏组织已经被用于实验性肾脏病模型。②旁分泌及内分泌机制。多项研究表明骨髓间充质干细胞不仅可以通过分泌多种生长因子和细胞因子抑制T细胞、B细胞反应及增生,而且对树突状细胞等抗原呈递细胞和NK细胞也有免疫抑制作用。因此,减轻炎症反应、调节肾组织微环境中细胞因子的分泌,可能是骨髓间充质干细胞促进肾脏细胞修复的重要机制。

 

背景:糖尿病肾病防治的基本措施包括有效控制血糖、控制血压、抑制肾素-血管紧张素系统和调脂治疗等,但往往无法获得理想的效果。

目的:探讨骨髓间充质干细胞移植糖尿病肾病大鼠的血糖及尿总蛋白改善情况。
方法:45只SD大鼠随机分为3组,每组15只,分别设为正常对照组、糖尿病肾病组和干细胞移植组。糖尿病肾病组和干细胞移植组一次性腹腔注射链脲佐菌素 60 mg/kg制备糖尿病肾病模型,正常对照组注射相同剂量的柠檬酸-柠檬酸钠缓冲液,造模后将2×106(200 μL)骨髓间充质干细胞直接注射到干细胞移植组大鼠左心室,首次移植后7 d进行第2次移植。正常对照组和糖尿病肾病组心内注射相同剂量的无血清L-DMEM培养基。治疗后1,4,8周检测3组大鼠的尿总蛋白和血糖。

结果与结论:①治疗后1,4,8周:干细胞移植组以及糖尿病肾病组的血糖及尿总蛋白水平均显著高于对照组(P < 0.05)。②治疗后1周:干细胞移植组血糖及尿总蛋白水平显著低于糖尿病肾病组(P < 0.05)。③治疗后4,8周:糖尿病肾病组血糖及尿总蛋白水平稍高于干细胞移植组,但差异无显著性意义(P > 0.05)。④实验结果表明,骨髓间充质干细胞移植治疗糖尿病肾病大鼠可以在短时间内获得良好的治疗效果,显著改善大鼠的血糖及尿总蛋白水平,但长期治疗效果不佳。

Abstract:

BACKGROUND: Common strategies for preventing diabetic nephropathy include effective control of blood sugar and blood pressure, inhibition of the rennin-angiotensin system and lipid-lowering therapy, but it is often difficult to get the desired results.
OBJECTIVE: To investigate the effect of transplantation of bone marrow mesenchymal stem cells on levels of blood glucose and urinary total protein in diabetic nephropathy rats.
METHODS: Forty-five Sprague-Dawley rats were randomly divided into three groups (n=15 per group): normal control group, diabetic nephropathy group and stem cell transplantation group. Rats in the diabetic nephropathy and stem cell transplantation groups were given single use of 60 mg/kg streptozotocin to make diabetic nephropathy models. The same dose of citric acid-sodium citrate buffer was injected in the normal control group. After modeling, 200 μL of bone marrow mesenchymal stem cell solution (2×106) was injected into the left ventricle of rats in the stem cell transplantation group, and then at 7 days after the first transplantation, the cell transplantation was conducted again. The same dose of serum-free L-DMEM was injected intracardially into the rats in the normal control and diabetic nephropathy groups. Levels of urinary total protein and blood glucose were detected. 
RESULTS AND CONCLUSION: At 1, 4, 8 weeks after treatment, the urinary total protein and blood glucose levels were significantly higher in the stem cell transplantation group and diabetic nephropathy group than the normal control group (P < 0.05). At 1 week after treatment, the urinary total protein and blood glucose levels were significantly lower in the stem cell transplantation group than the diabetic nephropathy group (P < 0.05). At 4 and 8 weeks after treatment, the total urinary protein and blood glucose levels were slightly higher in the diabetic nephropathy group than the stem cell transplantation group, but there was no significant difference (P > 0.05). These findings indicate that bone marrow mesenchymal stem cell transplantation in diabetic nephropathy rats can get good results in a short period, significantly improve the blood glucose and urinary total protein levels, but the long-term treatment effect is poor.
