文题释义:

胰岛素样生长因子Ⅰ:胰岛素样生长因子Ⅰ在神经发育、代谢和再生过程中至关重要,参与了糖尿病周围神经病变的发展变化,是治疗糖尿病周围神经病变的一个关键靶点。

胰岛素样生长因子Ⅰ蛋白:是由70个氨基酸组成的具有内分泌、自分泌及旁分泌特性的单链多肽,主要由人肝细胞合成和分泌,对人体生长发育起着重要调节作用。胰岛素样生长因子Ⅰ是生长激素产生生理作用过程中必须的一种活性蛋白多肽物质,受营养状态、激素和遗传等多因素的调节,具有促进神经生长和修复作用,糖尿病时胰岛素样生长因子Ⅰ及其受体作用降低是糖尿病周围神经病变的发病机制之一。

 

背景:中药复方糖痹康能够改善糖尿病大鼠神经传导速度,具有抗炎和抗氧化作用。胰岛素样生长因子Ⅰ是治疗糖尿病周围神经病变的一个关键靶点。
目的:观察中药复方糖痹康对糖尿病大鼠坐骨神经胰岛素样生长因子Ⅰ及其受体表达的影响。
方法:采用高脂加腹腔注射链脲佐菌素制备糖尿病模型大鼠,建模后分别灌胃糖痹康4.18,8.35,16.7 mg/(kg·d),并设置阳性对照弥可保组、模型组和正常对照组,灌胃16周。

结果与结论:与模型组相比,弥可保组血糖水平差异无显著性意义,糖痹康高剂量组血糖显著降低(P < 0.01)。免疫组织化学染色和实时荧光定量PCR检测显示,弥可保组、糖痹康高剂量组大鼠体质量、坐骨神经运动神经传导速度、坐骨神经组织胰岛素样生长因子Ⅰ及其受体蛋白和mRNA的表达均增高(P < 0.05或P < 0.01)。结果说明,糖痹康通过促进胰岛素样生长因子Ⅰ及其受体表达而起到防治糖尿病周围神经病变的作用。

Abstract:

BACKGROUND: Chinese medicine Tangbikang can improve nerve conduction velocity in diabetic rats, and has anti-inflammatory and antioxidant effects. Insulin like growth factor-I is a key target in the treatment of diabetic peripheral neuropathy.
OBJECTIVE: To observe the effect of Tangbikang on the expression of insulin-like growth factor-I and its receptor protein and mRNA in the sciatic nerve of diabetic rat model.
METHODS: The experimental diabetes mellitus rat models were induced by feeding high fat forage and injection with streptozotocin. After model establishment, rats were given Tangbikang 4.18, 8.35, 16.7 mg/kg per day. This study set positive control methycobal, model and normal control groups. Intragastric administration was performed for 16 weeks.
RESULTS AND CONCLUSION: Compared with the model group, blood glucose levels were similar in the methycobal group, but decreased in the high-dose Tangbikang group (P < 0.01). Immunohistochemical staining and real-time fluorescence quantitative PCR detection revealed that body mass, motor nerve conduction velocity, insulin like growth factor-I and its receptor protein and mRNA expressions were increased in the methycobal and high-dose Tangbikang groups (P < 0.05 or P < 0.01). Results indicated that Tangbikang can prevent and treat diabetic peripheral neuropathy by promoting insulin like growth factor-I and its receptor.
