This work aims to estimate the value of diffusion weighted imaging （DWI） and diffusion tensor imaging （DTI） in detecting early-stage kidney injury in type 2 diabetic patients with normoalbuminuria （NAU） versus microalbuminuria （MAU） prospectively. A total of 30 T2DM patients with normal kidney function were recruited and assigned to the NAU group （n = 14） or MAU group （n = 16） according to 8 h overnight urinary albuminuria excretion rate （AER） results. A contemporary cohort of health check-up recipients were included as controls （n = 12）. DWI and DTI scans were performed on bilateral kidney using SE single-shot EPI, and apparent diffusion coefficient （ADC） and fractional anisotropy （FA） of the renal parenchyma was determined from ADC and FA maps of the three groups. ADC and FA values were compared among the three groups. According to DWI with a b value of 400 s/mm^2, the MAU and NAU groups showed significantly lowered mean ADC values compared with the healthy controls （P 〈 0.01）. The mean ADC in the MAU group [（2.22± 0.07） × 10^-3 mm^2/s] was slightly lower than that of the NAU group [（2.31 ± 0.22） × 10^- 3 mm^2/s], but this difference was not statistically significant （P 〉 0.05）. The FAvalue in the MAU group was higher than that in the control group （0.45 ± 0.07 vs. 0.3±0.03, P = 0.004） but did not differ from that in the NAU group （0.42 ± 0.03）（P 〉 0.05）. ADC and FA values may be more sensitive than urine AER in reflecting early-stage kidney injury and, hence, may facilitate earlier detection and quantitative evaluation of kidney injury in T2DM patients. Combined evaluation of ADC and FA values may provide a better quantitative approach for identifying diabetic nephropathy at early disease stages.

Palaeoflood hydrology study is a leading subject in global change study. Through field investigation in the upper reaches of Hanjiang River, palaeoflood slackwater deposits （SWD） were found in the bedrock gorges of the Yunxi reach. The results of field observation, laboratory analysis including particle-size distribution and magnetic susceptibility, and com- parison with modern flood deposits, the SWD were identified as the most typical Holocene palaeoflood deposits of the Hanjiang River. By using stratig;aphic correlation and OSL dating method, the palaeoflood event was dated to be 3200-2800 a BP at the turn from the middle to late Holocene. According to the palaeoflood peak stage and hydraulic parameters, the peak discharges of the palaeoflood were reconstructed as 48,830-51,710 m3/s by using the slope-area method. At same time, the flood peak discharges of 1983, 2005 and 2010 severe floods were reconstructed with the same method and hydraulic parameters in the same cross section. The error between the reconstructed and gauged discharges was 1.99%-4.21%. This showed that the reconstructed palaeoflood peak discharges were reliable. The flood peak discharge-frequency relationship at 10,000-year time scale was established by a com- bination of the gauged flood, historical flood and palaeoflood hydrological data. These results are very important for hydraulic engineering and flood mitigation on the Hanjiang River.

2008年开始的美国次贷危机所引发的全球金融风暴已经越来越深地影响着我们的生活,这场金融风暴不仅对西方主要经济大国产生了深刻影响,而且也正在对发展中的中国产生前所未有的影响。在某种意义上说,这是中国自上世纪80年代开始社会经济转型以来面临的最大挑战,也是对中国执政党执政能力的最大考验。在这场席卷全球的金融风暴面前,中国社会科学工作者应该以自己的专业知识对这场金融风暴可能带来的风险、挑战及其机遇予以回应。为此,上海市高校人文社会科学重点研究基地上海大学中国社会转型与社会组织研究中心、上海高校社会学E-研究院和本刊编辑部联合邀请上海部分青年学者对此问题进行了讨论。虽然这场全球金融风暴开始不久,我们很难预测它对中国社会、政治、经济等方面的影响,但是,有一点是肯定的,影响是不可避免的,并且已经使我们感受到了。我们相信,全球金融风暴对于中国来说,不仅是风险和挑战,而且也是机遇。它会使具有中国特色的社会主义市场经济更加成熟,它会孕育一个建立在自己文化土壤上,同时又具有现代意义的"社会",它会培育和发展出"国家与社会"的新型关系。
