Atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured during various seasons at six different cities/locations in Qingdao alongshore. The annual average PAHs concentration ranged from 16 ng/m3 (at a clean com- pared site) to 308 ng/m3 (in an industry site). The average total particulate PAHs concentration was 74.5 ng/m3 with a higher concentration of particulate PAHs in winter. Based on a year-round dataset, the sources of PAHs in the air of Qingdao were drawn by principal factor analysis and correlation analysis. The results indicated that vehicle emissions and oil burning were the main source of PAHs in Qingdao alongshore.

目的探讨听觉诱导对昏迷病人早期意识恢复的作用。方法选择颅脑外伤昏迷且颅内无活动性出血的病人180例,随机分组;实验组按颅脑外伤昏迷病人常规治疗、护理加语言唤醒治疗;对照组按颅脑外伤昏迷病人常规治疗及护理;2组经脑干听觉诱发电位（BAEP）与脑电图（EEG）动态监测对结果进行比较分析。结果实验组BAEP与EEG阳性率、出现呼唤反应率结果显著优于对照组。结论语言唤醒疗法对颅脑外伤昏迷病人的早期意识恢复可起促进作用,应用听觉诱导指导语言唤醒疗法的实施是一种评价语言唤醒疗法疗效的新方法。

In this paper, we discuss the a posteriori error estimate of the finite element approximation for the boundary control problems governed by the parabolic partial differential equations. Three different a posteriori error estimators are provided for the parabolic boundary control problems with the observations of the distributed state, the boundary state and the final state. It is proven that these estimators are reliable bounds of the finite element approximation errors, which can be used as the indicators of the mesh refinement in adaptive finite element methods.

For local treatment of ulcerative colitis,a new azoreductase driven prodrug CDDO-AZO from bardoxolone methyl(CDDO-Me)and 5-aminosalicylate(5-ASA)was designed,synthesized and biologically *** is proposed that orally administrated CDDO-AZO is stable before reaching the colon,while it can also be triggered by the presence of azoreductase in the colon to fragment into CDDO-Me and 5-ASA,generating potent anti-colitis *** to olsalazine(OLS,a clinically used drug for ulcerative colitis)and CDDO-Me plus 5-ASA,CDDO-AZO significantly attenuated inflammatory colitis symptoms in DSS-induced chronic colitis mice,which suggested that CDDO-AZO may be a promising anti-ulcerative colitis agent.

Correlated firings among neurons have been extensively investigated;however,previous studies on retinal ganglion cell(RGC)population activities were mainly based on analyzing the correlated activities between the entire spike *** the present study,the correlation properties were explored based on burst-like activities and solitary spikes *** results indicate that:(1)burst-like activities were more correlated with other neurons’activities;(2)burst-like spikes correlated with their neighboring neurons represented a smaller receptive field than that of correlated solitary *** results suggest that correlated burst-like spikes should be more efficient in signal transmission,and could encode more detailed spatial information.
