The distribution of afferent terminals from VL nucleus to cruciate cortex was studied by using nerve fibers degeneration and electron microscopic technigues. Cortical area 4 could be further divided into three subdivisions according to their geographical relations to the eruciate sulcus: an anterior, a posterior and a lateral zone, respectively. It was demonstrated that the degenerating axon terminals were mainly distributed in anterior and lateral zones. Much less terminals were observed in the posterior zone. Totally 112 terminals were observed in the anterior zone. Among them, 78.6％ were seen in layer Ⅲ, 19.6％ in layer Ⅰ, 1.8％ in layer Ⅴ. Of the 112 terminals found in the lateral zone, 62.5％ were distributed in layer Ⅲ, 31.2％ in layer Ⅰ and 6.3％ in layer Ⅴ. On the other hand, only 33 degenerating terminals were found in posterior zone. their distributions were: 51.6％ in layer Ⅰ, 42.4％ in layer Ⅲ and 6.0％ in layer V. Approximately 75％ of the degenerating axon terminals examined in these three zones made synaptie contacts with dendritic spines, and 25％ with dendritic shafts. The vast majority of these synapses could be classified as asymmetrical type synapse.In area 6, most of the degenerating terminals were encountered in layer Ⅰ and Ⅲ. All of them formed asymmetrical type synapses with dendritic spines. No degenerating terminals could be found in area 3a.

Synaptic connections of commissural axon terminals from contralateral motor cortex have been studied by using anterograde degeneration and electron microscopy in the cortical area 4? of cat. The results showed that most of the commissural terminals display electron-dense type degeneration, and 92 degenerating terminals were identified in area 4?. The number of terminals in layer Ⅰ was nearly equal to layer Ⅲ. In layer Ⅲ, an asymmetrical synapse formed between a degenerating terminal and the soma of a bipolar cell was observed. In layers Ⅴ-Ⅵ, no degenerating terminal could be found. Among the total degenerating terminals, 77.2% were found to make synapses with dendritic spines, 21.7% made synapses with dendritic shafts and 1.1% with soma, and all of these synapses were of the assymmetrical type.

Traditional Chinese medicine (TCM) with the characteristics of holistic view and treatment based on syndrome differentiation, has rich clinical experience thousands of years and demonstrates promising effects to cure complex disease. However, due to the features of multi-component, multi-target and synergistic effect existed in TCM, the effective substances and mechanisms of action are not clear, the qualities of TCM are out of control, and scientific and correct assess system is waiting to be established. The network pharmacology is a novel subject based on the construction of multi-layer networks of disease-phenotype-gene-drug to predict the drug targets in a holistic view, and promote efficiency of drug discovery. Methodologically, network pharmacology integrated the notions of comprehensive research and systematic assessment which agree with the characteristics of holistic view and treatment based on syndrome differentiation in Chinese medicine. Our paper reviewed the challenge and chance within the modernization of TCM, the concept and technology of network pharmacology, and its preliminary application in investigation of TCM. The theoretical system of network pharmacology is emphasized, and the potential prospect of its application in modernization in TCM is focused.

Congenital disorders of glycosylation(CDG) are a rapidly growing group of genetic diseases that are due to defects in the synthesis of glycans and in the attachment of glycans to other compounds. Most CDG are multisystemic diseases often involving severe psychomotor retardation. The CDG causing sialic acid deficiency of N-glycans can be diagnosed by isoelectric focusing of serum transferrin. Glycan structural analysis, yeast genetics and knockout animal models are essential tools in the elucidation of novel CDG. In this review, we focus on the current knowledge of the pathogenesis and identification of nine primary glycosylation diseases.
