[To attach great importance to the identification of refractory myasthenia gravis].

Refractory myasthenia gravis is an intractable state during treatment. The common causes of refractory treatment in most patients include: overwork, malnutrition, infections, insomnia, cognitive and emotional disorders, and so on. Only targeting the poor curative effect from the surface of the intractable state caused indecisive decisions and is difficult to win a success. Therefore, identifying "refractory state" can not only see the essence through the phenomenon, but also apply the right medicine, thereby killing two birds with one stone.
