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.

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.

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.

Palmer-foot hyperhidrosis is one kind of focal hyperhidrosis, with symptoms of sweating hands or feet. Some people even have sweat dripping off their hands or feet. This article studied the views of TCM on palmer-foot hyperhidrosis, expounded the pathological and physiological relationship between palmer-foot hyperhidrosis and spleen and stomach, and proposed that clinical treatment should be based on the syndrome differentiation and treatment of spleen and stomach, which can achieve certain efficacy.

Objective To evaluate acoustic effects of laryngeal microsurgery on vocal polyp, vocal cyst and vocal leuko- plakia. Methods 300 cases in vocal fold diseases were measured acoustically pre - and post - microsurgery. Results After openation, jitter, shimmer and NNE decreased statistically in vocal polyp and vocal cyst patients, and did not improve in vocal leukoplakia patients. Whether or not the surgery was done, F0 of all patients did not change Conclusion Laryngeal microsurgery had definite effect on clearing benign focus. After surgery, vocal functioin improved in vocal polyp and cyst patients, and in vocal leukoplakia, there was no improvement in such a short time as one week.

Objective To study the association between adults'respiratory health and elements concentrations in aerometric particulate matters and provide information about the effect of air pollution sources on human health. Methods Health question nairs were administered to 7 661 male and 7 673 female adults in 4 Chinese cities. 42 elements in particulate matters of both urban and rural areas were analyzed by XRF. The data were analyzed by using two-stage regression, the Logistic regression for the first stage and weighted linear regression for the other. Adult's respiratory health parameters were obtained by 1st stage analysis. The association of the elements in PM and adults'respiratory health parameters of 8 sites in the 4 cities was established. Odds ratios were given using the weighted linear regression model. Results Positive associations between adults'respiratory health and crust elements (Al, Ca, Fe, Si, Ti) and pollution elements (As, Ni, Cd, Pb) in PM2.5-10 or PM2.5 were found (OR=1.00-1.12). Associations of respiratory health parameters with elements in fine particle (OR=1.03-1.61) were stronger than those with elements in coarse particle (OR=1.03-1.12) in the case of the equal element concentrations. Conclusion An assumption of 'crust particle groups' was brought forward to give an explanation to the relation between crust elements and respiratory health. It assumed that the relation is an indirect one, since 'crust particle groups' in PM act as carrier of toxic matters and/or bacteria. The result points out that it should pay much attention to controlling of PM from soil as well as controlling of industrial pollution.

As a member of GTPase Rab family,Rab10 protein is not only involved in vesicle formation,transport,anchoring and fusion process,but also affects the occurrence and development of tumors.Research about the mechanisms of Rab10 in intracellular vesicle transport and tumor may provide a potential target and new idea for the anti-cancer therapy.
