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.

Objective To compare the spray characteristics of domestic and foreign nasal spray delivery devices for live attenuated influenza vaccine(LAIV). Methods The particle size distribution(DV10,DV50 and DV90),the proportion of droplets smaller than 10 μm and Span of atomized particles of two brands of nasal spray delivery devices at home and abroad were measured by laser diffraction method,the spray pattern[maximum diameter(D_(max)),shortest diameter(D_(min))and ovality(D_(max)/D_(min))]and spray geometry(spray angle and width)were detected by Spray view,and the comparative analysis was performed. Results There was no significant difference in DV10,DV50,DV90 particle size distribution,proportion of droplets smaller than 10 μm and Span of atomized particles between the two kinds of domestic and foreign nasal spray delivery devices[F-values of Levene's test for equality of variances were 0. 622,0. 135,3. 067,0. 212 and 0. 058,P-values were0. 434,0. 714,0. 085,0. 647 and 0. 810,and significance(two-tailed)values of equal variances assumed were 0. 439,0. 228,0. 281,0. 539 and 0. 910,respectively];D_(max),D_(min)and ovality of the spray patterns showed no significant difference[F-values of Levene's test for equality of variances were 2. 102,2. 666 and 0. 514,P-values were 0. 158,0. 114 and0. 479,and significance(two-tailed)values of equal variances assumed were 0. 651,0. 407,and 0. 160,respectively];The geometric mean ratios of spray angle and width were 0. 92 and 0. 91,respectively,which ranged from 0. 90 to 1. 11.Conclusion Both the domestic and foreign nasal spray delivery devices meet the delivery requirement of the nasal spray LAIV,which can be used for the delivery of nasal spray vaccines and drugs.

Objective To investigate the use of anti-infective drugs in outpatients of our hospital, and to pro-mote rational administration in clinic. Methods Collecting the prescriptions of out-patient during June 2007 in our pharmscy,then statistically analyze the anti-infective drugs information in combination with adverse drug reaction (ADR) reports. Results The percentage of prescriptions was 45. 8%, the average amount of the prescriptions was 62. 56 yuan,the cost of anti-infective drugs accounted for 41.8% ,prescriptions of combined use and injection were 39.5% and 37.2% ,the ratio of ADR was 80. 6% ,irrational administration accounted for 10. 8%. Conclusion The use of anti-infective drugs in our prescriptions of out-patients has some problems, but rational use is the main trend in our hospital.

The deposition of amyloid β-protein (Aβ is the key pathological basis of cerebral amyloid angiopathy (CAA) and Alzheimer's disease (AD). The current studies emphasis that the stability of internal environment between cells of the neurovascular unit is the key to maintain normal brain function. This article reviews the relationship between the Aβand the neurovascular unit injury, and we expect to provide some new ideas for the clinical prevention and treatment of CAA and AD.

There are many therapeutic drugs for rheumatoid arthritis(RA) treatment,but the pathogenesis of RA have not been fully understood,therefore no curable drug has been found.With increasing knowledge of the inflammatory process,especially in signaling,some drugs modifying disease progress and interfering signaling pathways have been studied.Cytokine inhibitors such as tumor necrosis factor-blocking agents and IL-1 receptor antagonist in clinical trials and in practice have resulted in dramatic improvement in RA disease control.Important molecular mechanisms of actions on total glucosides of paeony(TGP) and Glucosides of Chaenomeles speciosa(GCS) were showed to modulate G protein-AC-cAMP and Ras-MAPKs signaling pathways and to inhibit synoviacytes proliferation.This review focuses on agents which target various cytokines,other inflammatory mediators,antigen of cells,and signaling pathways.

Liver fibrosis can be classified as a wound-healing response to a variety of chronic stimuli,and is characterized by an excessive deposition of extracellular matrix(ECM)proteins.Hepatic stellate cells(HSCs)are presently regarded as one of the key cell types involved in the progression of liver fibrosis.Following a fibrogenic stimulus,HSC changes from a quiescent to an activated,collagen-producing cell.Each cellular response to extracelluar stimuli must be framed in a scenario.Along these lines,the identification and characterization of intracellular signaling pathways activated by different stimuli in HSCs represent a mandatory step.Drug targets which aim at the extra-cellular signals or intra-cellular cascades are required for ameliorating liver fibrosis.

Liver fibrosis is the excessive accumulation of extracellular matrix (ECM) proteins that occurs in most types of chronic liver diseases. Hepatic stellate cells (HSCs) are major sources of the excess ECM deposited in fibrotic liver. Transforming growth factor ? (TGF-?) is considered to play a generic role in the development of tissue fibrosis, as it stimulates the synthesis and deposition of ECM components. Smad pathways are central mediators of signals from the receptors for transfor- ming TGF-? to the nucleus. However, growing biochemical and developmental evidence supports the notion that non-Smad pathways also participate in TGF-? signalling. TGF-? signalling pathways play an important role in regulating tissue homeostasis and have been implicated implicated in diverse pathological conditions. It is oow our challenge to design ways of blocking the fibrosis-specific actions of TGF-? through downstream signalling pathways and mediators without compromising the other activities of this multifunctional cytokine, which is essential for health.
