Conclusion: The IQ of children with ADHD is lower than that of normal children, especially the balance between VIQ and PIQ.

The species of bromine and iodine in aerosol samples were extracted using ultra-pure water-ultrasonic method with different time in-length and pressurizing decomposition with dilute ammonia, respectively. The efficiency of extraction and the stability of bromine and iodine species were compared under different extraction) conditions. Results showed that(1) the efficiency of extraction using pressurizing decomposition, which might destroy some unknown form of organic iodine, was relatively higher than the one by ultrasonic method;(2) I~- was unstable in added standard cellular blank filter during ultrasonic assisted extraction for long time;(3) The optimum condition was ultra-pure water-ultrasonic assisted extraction for 5 min. Moreover), the suitability of glass microfiber filter(GF) and cellular filter(CF) during extraction for bromine and iodine) species in aerosol was also compared, which indicated that GF is favorable for species analysis than CF under different kinds of extraction conditions. Based upon the extraction results, HPLC-ICP-MS approach was developed to analyze bromine and iodine) species in atmospheric aerosol. The total iodine, bromine and species in the aerosol samples collected in Hefei were then determined accordingly. The levels of total bromine and iodine) in Hefei aerosols were 883 and 231 pmol/m~3, respectively. Br~- was found to be dominant species with 68%, while BrO_3~- was undetectable. 70% of total iodine occurred as unidentified forms including soluble organic) iodine and insoluble iodine.

At present, there are many effective ways to achieve high performance in cluster system storage management, including server-end disk, server-end caching, local caching and cooperative caching. The cooperative caching mechanism shares caches among different clients so as to avoid expensive disk access costs and to improve overall throughput of cluster system. In this paper, a Single Copy Cooperative Cache model is proposed together with block lookup algorithm, block replacement algorithm and the consistency algorithm based on the model. Meanwhile, the prototype system of the model is implemented in PVFS file system. Finally, the performance of this system is tested in InfiniBand Framework, the result of which shows that in contrast to the original PVFS system, read performance of PVFS file system is improved by about two times, while write performance is reduced by nearly ten percent.

[ Abstract] Ischemic brain injury is closely associated w ith oxidative stress, neuron loss, and inflammatory reaction. The thioredoxin system is an important antioxidant system in human body. It plays the important roles in the process of fighting against oxidative stress damage, inhibiting apoptosis and inflammation. In recent years, the roles of thioredoxin system in cerebral ischemia have attracted more and more attention. This article review s the roles of thioredoxin in cerebral ischemia.

Objective To investigate the current situation of management of institutions of schistosomiasis prevention and control in Hubei Province so as to explore the probable competency building standards for these institutions at the county and township levels. Methods By using a combination of quantitative and qualitative methods the institutions of schistosomiasis prevention and control at county and township levels were investigated for the institutional setup staffing and fulfillment func-tions since the reform of 2004. Results Among 63 schistosomiasis endemic counties cities districts of Hubei Province there were 26 independent schistosomiasis control institutions 41.27% there were 24 institutions which were incorporated in-to CDC 38.10% and there were no institutions in 13 counties 20.63% . Among 518 endemic towns there were 299 institu-tions 57.72% . The total staffing size were 1 932 but there were 1 586 82.09% people actually working in the post and therefore there were 346 17.91% empty positions. The average rates of carrying out the six functions were 91.48%-71.19%but only 19.23%of the institutions participated in the comprehensive schistosomiasis control management project and its effect assessment. Conclusion According to the management model for schistosomiasis control institutions under the current institu-tional mechanisms we need a rigorous industry standard to constrain guide and standardize the management and capacity-building of the institutions in different historical periods.
