3.Methods Clinical data of 36 cases of Cushing?s disease with normal MR finding were analyzed retrospectively. Besides one Nelson syndrome case,the other 35 patients had typical clinical manifestations of hypercorticoidism.
方法　回顾性分析 36例MRI未见异常的库欣病的临床资料 ,除 1例Nelson综合征外 ,其余 35例均有典型的皮质醇增多症的表现。收藏指正
4.When the kinetic energy matrix have been diagonalzed, under the condition A=aE or A≠aE,the common method of finding normal coordinate is given. Besides,other two methods of finding normal coordinate are given,one method is by changing the coordinate scales and diagonaling the new kinetic energy matrix, the other method is by changing the coordinate scales and using arbitrary row of adjoint matrix of the frequency eigen matrix.
