The patient showed atrophy in frontal and temporal lobe on regular MRI, significantly reduced amount of Nacetyl aspartic acid、cholineand creatinecompared with contralateral on MRS , remarkably decreased blood flow in the left temporal polar and front part of fontal lobe compared with contralateral on PWI. There were decreased association fibers between Broca and other regions meanwhile no association fibers were found between triangular area and wernicke region on DTI. The fibers projecting to opercular part of frontal lobe via archiform fibers were lessened. The mean FA and fibers of Broca and Wernick regions were less than that of the healthy subjects.

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.
