Authors had prepared the high-quality sectioned images of a cadaver head. For the delineation of each cerebral gyrus, three-dimensional model of the same brain was required. The purpose of this study was to develop the segmentation protocol of cerebral gyri by referring to the three-dimensional model on the personal computer. From the 114 sectioned images (intervals, 1 mm), a cerebral hemisphere was outlined. On MRIcro software, sectioned images including only the cerebral hemisphere were volume reconstructed. The volume model was rotated to capture the lateral, medial, superior, and inferior views of the cerebral hemisphere. On these four views, areas of 33 cerebral gyri were painted with colors. Derived from the painted views, the cerebral gyri in sectioned images were identified and outlined on the Photoshop to prepare segmented images. The segmented images were used for production of volume and surface models of the selected gyri. The segmentation method developed in this research is expected to be applied to other types of images, such as MRIs. Our results of the sectioned and segmented images of the cadaver brain, acquired in the present study, are hopefully utilized for medical learning tools of neuroanatomy.

OBJECTIVETo observe the therapeutic effect of eye acupuncture on cognition disorders in patients of chronic cerebral circulation insufficiency (CCCI).

METHODSSixty cases were randomly divided into an observation group and a control group, 30 cases in each group. All patients were treated with oral administration of compound Danshen tablets, and the observation group was treated with eye acupuncture based on the pharmacotherapy and upper energizer area, kidney area, spleen area were selected. Their therapeutic effects were observed after 8 weeks.

RESULTSThe total effective rate of 80.0% in the observation group was better than that of 53.3% in the control group (P<0.05). The score of mini-mental state (MMSE) in the observation group was also higher than that in the control group (P<0.05).

CONCLUSIONEye acupuncture has a good effect on cognition disorders in patients of CCCI and can enhance life quality of the patients.
