BACKGROUND： Acupuncture has been used as a treatment for cognitive impairment. OBJECTIVE： This review assesses clinical evidence for or against acupuncture as a treatment for cognitive impairment. This review also discusses the proposed mechanism（s） that could link acupuncture to improved cognitive function. METHODS： We searched the literature using Polyuone search from its inception to January 2013, with full text available and language limited to English. Levels of evidence were examined using Oxford Centre for Evidence-based Medicine-Levels of Evidence （March, 2009）. RESULTS： Twelve studies met the inclusion criteria： 3 human studies and 9 animal studies. Levels of evidence ranged from level lb to level 5. CONCLUSION： Most animal studies demonstrated a positive effect of acupuncture on cognitive impairment. However, the results of human studies were inconsistent. Further high-quality human studies with greater statistical power are needed to determine the effectiveness of acupuncture and an optimal protocol.

Brominated flame retardants have been widely used in industry. There is a rapid growing public concern for their availabilities in the environment. Advanced oxidation process （AOP） is a promising and efficient technology which may be used to remove emerging chemicals such as brominated flame retardants. This study aims at investigating optimal operational conditions for the removal of BDE-209 using nano-scaled titanium（IV） oxide. The residual PBDE congeners after photocatalytical degradation of BDE-209 by TiO2 were analysed by gas chromatography-mass spectrometry （GC-MS）. It was found that the degradability of BDE-209 by TiO2 was attributed to its photocatalytic activity but not the small size of the particles. The half-life of removing BDE-209 by TiO2 was 3.05 days under visible light. Tetra- and penta-BDEs were the major degraded products of BDE-209. Optimum conditions for photocatalytical degradation of BDE-209 was found to be at pH 12 （93% ± 1%）, 5, 10, 20 mg/L （93.0% ± 1.70%, 91.6% ± 3.21%, 91.9% ± 0.952%, respectively）, respectively of humic acid and in the form of anatase/rutile TiO2 （82% ± 3%）. Hence, the efficiency of removing BDE-209 can be maximized while being cost effective at the said operating conditions.

土壤水分是固沙植被的主要驱动因子,受地形、植被和气候的相互作用影响。本研究以古尔班通古特沙漠半固定沙丘上的土壤水分为研究对象,采用广义线性、广义加性和随机森林等模型,研究了不同微地貌类型和深度的土壤水分与地形-植被因子之间的关系。结果表明:除了迎风坡上表层(0~40 cm)土壤水分之外,沙丘不同微地貌类型和深度的土壤水分之间差异不显著;与植被因子相比,地形因子对不同深度土壤水分的影响更显著;地形因子坡度和高差与土壤水分含量呈负相关关系,而坡向与土壤水分含量呈正相关关系;植被因子的灌木盖度和生物量也对土壤水分呈现负向趋势;针对不同深度的土壤水分与地形-植被因子的关系建模上,随机森林模型优于广义线性和广义加性模型。研究结果为该地区未来固沙植被保护工作提供了理论指导。
