The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

The results are as follows.(1) Long train electrical stimulation at the dMNF facilitated myoelectric activities of genioglossus and phrenic muscle.(2) Short train electrical stimulation of dMNF, when delivered in the inspiratory phase, caused prolongation of myoelectric activities of genioglossus and phrenic muscle; but when delivered in the expiratory phase, myoelectric activities of genioglossus and phrenic muscle were shortened.(3) Long train electrical stimulation at the vMNF inhibited myoelectric activities of genioglossus and phrenic muscle.(4) Short train electrical stimulation of vMNF caused shortening of myoelectric activities of genioglossus and phrenic muscle, when delivered in the inspiratory phase, but a prolongation when delivered in the expiratory phase.(5) The effects of microinjection of glutamate to dMNF and vMNF were similar to those of electrical stimulation.

结果如下：(1)长串电脉冲刺激dMNF引起颏舌肌和膈肌肌电活动明显增强；(2)短串电脉冲刺激dMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动延长，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动提前终止；(3)长串电脉冲刺激vMNF使颏舌肌和膈肌肌电活动明显被抑制；(4)短串电脉冲刺激vMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动提前终止，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动延长；(5)在dMNF和vMNF分别微量注射谷氨酸钠，其效应与电刺激结果基本一致。

The results showed an increased mean jitter value, fiber density and abnormal percentage both in EDC and AT muscles in group 1 and II diabetic patients comparing to the normal controls. These findings suggest an impaired or immatured neuromuscular junctions and an evidence of reinnervation through axonal sprouting in the diabetic patients either with or without nerve conduction abnormalities. In conclusion, the changes of axonal degeneration and reinnervation are the main pathophysiological mechanism of diabetic neuropathy, and the SFEMG is more sensitive than routine nerve conduction study in the diagnosis of diabetic neuropathyKeyword Axonal degeneration , diabetes mellitus , neuropathy , single fiber electromyography

结果显示两组糖尿病病患的连续间值差异，肌纤维密度及不正常比率比对照组显著增加(t试验，依序p.01)，在第一组糖尿病患中，伸指总肌的连续波间值差异比第二组高(p.05)，而连续波间值差异与纤维密度之间也成线性相关的增加(伸指总肌，r=0.471，p.01；胫前肌，r=0.386，p.02)，在伸指总肌测得的连续波间值差异上，第一组糖尿病患有75%不正常，第二组有33.3%不正常，而在胫前肌的连续波间值差异上，第一组糖尿病患有83.3%的不正常，第二组有75%不正常，在肌纤维密度的测定中，第一组糖尿病患的伸指总肌有27.8%不正常，胫前肌有58.3%不正常，第二组病患的伸指总肌有25%不正常，胫前肌有41.7%不正常，此结果表示糖尿病神经变造成的神经肌像交接处不稳定及有神经轴再生的重分布现象，因此也证实糖尿病神经病变的主要病理机转为神经的退化所致，而在诊断上单纤维肌电图检查的敏感度也比运动神经传导速度检查为高。
