Methods A retrospective study was conducted in 84 patients with MG from July 1995 to December 2009. The following factors were evaluated: sex,age,history of preoperative myasthenic crisis,Ossermen classification, steroid hormones use and anticholinesterase drugs before operation,operation methods,operation time,thymoma,展开更多

This paper tested the hypothesis through quantitative test. The results showed that system factors mainly resulted in low productivity, and the natural disaster should not be ignored.展开更多
