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 evaluate the effectiveness of minocycline at subantimicrobial dosage in the treatment of experimentally induced periodontitis in rats.Methods: Periodontitis was induced by silk ligature technique on 4 second molars in each of 16 adult male Sprague-Dawley rats and the animals were fed with 100 g/L sucrose drink. The rats were divided into 2 groups: (1)periodontitis group without treatment;(2)treatment group, the rats with periodontitis were treated by systemic administration of minocycline at 5 mg/(kg?d).Another 8 normal rats were used as the controls. Assessment was carried out at day 28 and 56 using a number of different visual, histological and ultrastructure approaches.Visual assessment included tooth mobility(TM), gingival index(GI), and alveolar bone loss. Histological examination included monocyte effusion,resorption lacunae with osteoclasts and percentage of the periodontal collagen.The collected data were statistically analyzed using variance test.Results: Systemic administration of minocycline at subantimicrobial dosage can significantly reduce GI, TM, resorption lacunae with osteoclasts and alveolar bone loss either at day 28 or at day 56; significantly inhibited monocyte effusion and the collagen degradation in the periodontium at day 56 in rats with periodontitis. Conclusion: Minocycline at subantimicrobial dosage may decrease alveolar bone loss and osteoclasts formation in periodontium with periodontitis.

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.

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 study the effect of recombinant human endostatin hormone combined with transcatheter arterial chemoembolization (TACE) for the treatment of primary hepatocellular carcinoma (HCC).Methods Fifty-two primary HCC patients were divided into combined group (26 patients) and control group (26 patients) by random digits table method.The patients in combined group received TACE and recombinant human endostatin hormone added in embolism emulsion.The recent curative effect,level of serum vascular endothelial growth factor (VEGF),adverse reactions,recurrence rate and survival rate were compared between two groups.Results The response rate(RR) and clinical benefit rate(DCR) in combined group were 57.69％(15/26),84.62％(22/26),in control group were 34.62％(9/26),73.08％(19/26),there were significant differences (x2 =5.237,P ＜ 0.05 ; x2 =4.284,P ＜ 0.05).The 7th,14th,28th day after TACE,the level of VEGF in two groups was first increased and then a downward trend,the difference were statistically significant (P ＜ 0.05).The level of VEGF in combined group was significantly lower than that in control group (P＜ 0.05).The follow up rate was 94.23％(49/52),the 1-year and 2-year recurrence rate in combined group was significantly lower than that in control group (P＜ 0.05).The 2-year and 3-year survival rate in combined group was significantly higher than that in control group (P ＜ 0.05).Conclusion With TACE plus recombinant human endostatin hormone can effectively inhibit the increase of serum VEGF level,improve curative effect and disease control rate,reduce tumor recurrence and improve survival rate.
