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.

Methods:The films of a dry laser printer(Konica Drypro 752) and a paper printer (Locus) on 100 patients were interpreted by three radiologists(with five years and above experience).The time interval was two weeks .Results:There was no significant difference between the dry laser printer and paper printer for cerebral lacunae infarction.Concusion:For cerebral lacunae infarction, images obtained from a dry laser printer are similar to those from a paper printer.Thus, the former printer can be used for cerebral lacunae infarction.

Age-related macular degeneration ( AMD ) is one of the important eye diseases of the WHO present three big blindness, is one of the main blinding eye disease in people over the age of 50, people over the age of 65, about 2% of the disease caused by monocular blindness, as the population ages, AMD prevalence is increasing in our country. AMD with respect to its clinical manifestations can be divided into dry AMD and wet AMD, wet AMD is the most harmful for the vision of patients, at present there are many treatments for AMD ( mainly for wet age-related macular degeneration ) , mainly including laser treatment, drug therapy, surgical treatment, gene therapy, etc. The treatments of AMD would be illuminated in this article.

Based on the "Grayscales average distribution" method which equally distributes the input gray levels to output gray levels, three improved methods named: "Reduce the gray range expressed by the less significant subfields", "Low levels preset" and "Modify the exponent of inverse-gamma function" are proposed in this paper. Using these methods, the inverse-gamma relation subfields code can be obtained easily which can improve the low level expressions of AC-PDP. And a program, "gray scales distribution validate program", which can enhance the expressions of the demanded gray levels range, is also proposed in this paper.
