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 explore the relevant factors influencing the prognosis of progressive cerebral infarction,in order to provide basis for clinical trentment and improve the prognosis of patients.Methods Clinical data of 163 patients admitted as progressive cerebral infarction and 355 patients admitted as non-progressive cerebral infarction were retrospectively analyzed.All patients were followed up by interview or telephone at the time of 30 and 90days,the clinical data were recorded.The relevant factors influencing the prognosis of progressive cerebral infarction were analyzed.Results Multiple linear regression analysis of patients with progressive cerebral infarction showed that total anterior circulation infarcts,respiratory infection,coronary heart disease history,imbalance of water and electrolyte,white blood cell increasing were leading influence risk factors for the higher National Institutes of Health Stroke Scale(NIHSS) in hospitalized patients.Analysis of patients with progressive cerebral infarction showed that total anterior circulation infarcts,lack of physical activity,NIHSS at admitting,the elderly and respiratory infection were leading influence risk factors of the higher Activities of Daily Living(ADL) and modify Rankin Scale(mRS) scores at 30d and 90d of following up.The scores of ADL and mRS at 30d and 90d were significantly higher in progressive cerebral infarction than those of non-progressive cerebral infarction patients (t =6.6179,P =0.000,t =5.2788,P =0.000,t =5.0608,P =0.000,t =4.0725,P =0.000,respectively).The recurrence of cerebral infarction in progressive cerebral infarction group and death events at 30d were also significantly higher than that of non-progressive cerebral infarction(x2 =8.423,P =0.004 and x2 =5.135,P =0.023,respectively).But the recurrence of progressive cerebral infarction and death events at 90d,there were no significant differences between progressive cerebral infarction and non-progressive cerebral infarction (x2 =1.938,P =0.159 and x2 =3.518,P =0.061,respectively).Conclusion The relevant factors influencing the prognosis of progressive cerebral infarction are common effect of various factors.In the treatment of progressive cerebral infarction should be actively considered as much as possible to improve the prognosis of patients.

Objective To assess the clinical siginificance of the cardiopulmonary resuscitator in respiratory and cardiac arrest patients by comparing the curative effect of cardiopulmonary resuscitator and bare-handed cardiopulmonary resuscitation. Methods 102 patients on the verge of the death were randomiy divided into two groups and begin to CPR in four seconds after confirmation of respiratory and cardiac arrest. Patients in group 1 were given bare-handed CPR. Patients in group 2 were given cardiopulmonary resuscitation by cardiopulmonary resuscitator. Patients in both group 1 and group 2 received lasting CPR according to the 2010 GUIDE of CPR, then we observed their self-heart-beating, self-breathing, caroid puise, expression, puplillas, ECG. Results In the group 1,the effective case was 1,the non-effcctive cases were 63,the effective rate was 1.56%. In the group 2, the effective cases were 6, the non-effective cases were 31, the effective rate was 16.21%, there was a statistically significant difference between two groups ( <0.01) . Conclusion Cardiopulmonary resuscitator has good effect in cardiopulmomary resuscitation for respiratory and cardiac arrest patients, and the effective rate is significantly higher than bare-handed CPR,so it deserves clinical promotion.

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.
