Recent studies demonstrate that autistic spectrum disprders children have deficits in executive functiony, particularly the function referred response inhibition. The antisaccade task provides a new tool for direct evaluation of inhibitory function and a new way to explore the character of response inhibition in children with cognitive impairment. Researchers have used the technologies of eye movement to reveal the ability of oculomotor inhibition in children with autistic spectrum disprders, which is poorer than that of normal children.

Inflammation reaction and immune response are in-separable in the levels of system, tissue, cell and molecule. In-flammatory immune responses ( IIR) is proposed in this paper, which is defined a moderate or abnormal system responses of in-flammatory immune related cells in responding to the internal and external environment changes of body. It is described briefly that the research progresses of inflammatory immune cells ( e. g. , macrophages, dendritic cells, T cells and B cells, etc. ) and non-inflammatory immune cells ( e. g. , glial cells, endothe-lial cells, epithelial cells, fibroblasts, synovial cells and liver cells, etc. ) , and cytokines/receptor signal transduction in-volved in IIR. Moreover, the existing problems about regulating IIR drugs clinically are summarized. It is firstly put forward that soft regulation of inflammatory immune responses ( SRIIR) is a new direction of discovery and development of new drugs for the treatment of IIR related diseases.
