摘要
目的观察中药加味补肝汤对实验性糖尿病周围神经病变大鼠坐骨神经脑源性神经生长因子(brain-de-rived neurotrophic factor,BDNF)表达的影响,探讨其对实验性糖尿病大鼠周围神经病变的防治作用。方法加味补肝汤与甲钴胺作为对照,用1%链脲佐菌素诱发糖尿病模型,运用逆转录-多聚酶链式反应(reverse transcription-polymerasechain reaction,RT-PCR)技术检测模型大鼠坐骨神经中BDNF mRNA的表达。结果模型组坐骨神经中BDNF阳性的表达比正常对照组明显减少(P<0.05),模型组中第8周末BDNF表达比4周末增多。甲钴胺组、加味补肝汤比模型组增多(P<0.05),但甲钴胺组与加味补肝汤组比较差异无统计学意义(P>0.05)。结论加味补肝汤能上调糖尿病大鼠坐骨神经中BDNF的表达,对糖尿病大鼠周围神经病变有一定的防治作用。
Objective To observe the intervene effects of Jiaweibugan decoction on expression of brain-derived neurotrophic factor（BDNF）in sciatic nerve of experimental diabetic rats,and to explore the preventive and therapeutic effects of Jiaweibugan decoction on peripheral neuropathy.Methods Jiaweibugan decoction with mecobalamin was as control.The diabetic rats were induced by streptozotocin.Reverse transcription-polymerase chain reaction（RT-PCR）was used to determine the expression of BDNF mRNA in sciatic nerve. Results For the model rats, the expressions of BDNF protein in sciatic nerve were lower than those in the normal control group （P〈0. 05）, and higher at the 8th week than at the 4th week. The BDNF expressions were significantly higher in model rats treated by Jiaweibugan decoction and mecobalamin than in non-treated model rats （P〈0. 05）, but there was no significant difference between mecobalamin and Jiaweibugan decoction treatment. Conclusion Jiaweibugan decoction can increase the expressions of BDNF in sciatic nerve of diabetic rats, and has preventive and therapeutic effects on peripheral neuropathy in experimental diabetic rats.
