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。

Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.
