董仲舒王道观由“三才”向“三纲”之嬗变,蕴含着由法天以为仁到本天以立仁(人)的思想。这同时意味着“元”机展露与开显。纵向层面,董子之天备具了本然性根基,从而使天哲学乃至“天人一”得以确立;横向维度,天地人以及物共“元”之性而成“天下一”。董子王道观于“元”的确认中从终极意义上证成了王道本正的先天依据,并由此建构了“天人一”与“天下一”统一的“王天下”图式。

丙烯酰胺作为化妆品风险物质,具有神经毒性和潜在的致癌性,对于儿童的健康和生长发育具有一定危害。目前化妆品中丙烯酰胺的残留研究主要集中于聚丙烯酰胺类原料。本文对29批次市售儿童洗沐产品以及10批次椰油酰胺丙基甜菜碱(CAB)中丙烯酰胺残留进行了分析。结果表明:29批次产品中丙烯酰胺检出率为62%,残留量为0.010~0.151 mg/kg,其中不含聚丙烯酰胺类原料的样品中检出丙烯酰胺的比例为52%,均含有CAB;10批次原料CAB中丙烯酰胺检出率为100%,残留量为0.016~1.082 mg/kg,不同厂家、不同批次差异较大,且丙烯酰胺未作为CAB的风险杂质成分进行控制。丙烯酰胺来源途径较多,本文探索性地提出了化妆品中一种丙烯酰胺来源,并探讨了其产生的原因、安全风险评估以及国内外的监管情况,以期为儿童化妆品的质量控制以及原料监管提供参考。

Magnetic Properties as Indicators of Cu and Zn Contamination in Soils

引用

Pedosphere 2008年第4期18卷 479-485页

作者： LU Sheng-Gao bai Shi-qiang FU li-Xia College of Environmental and Resource Sciences Ministry of Education Key Laboratory of Environmental Remediation and Ecosystem Health Zhejiang University Hangzhou 310029 （China）

Concentrations of copper （Cu） and zinc （Zn） and various magnetic parameters in contaminated urban roadside soils were investigated using chemical analysis and magnetic measurements. The results revealed highly elevated Cu and Zn concentrations as well as magnetic susceptibility in the roadside soils. The mean concentrations of Cu and Zn in these roadside soils were almost twice those in average Chinese soils, with the mean magnetic susceptibility of the roadside soils reaching about 179 ×10^-8 m^3 kg^-1. This enhanced magnetic susceptibility was attributed to the presence of anthropogenic soft ferrimagnetic particles. A low frequency-dependent susceptibility （2.5%± 1.0%） observed in the roadside soils indicated the coarse multidomain （MD） ferrimagnetic grains to be the dominant contributor to magnetic susceptibility. The Cu and Zn concentration of the soils had highly significant linear correlations with magnetic susceptibility （P 〈 0.01）, anhysteretic remanent magnetization （P 〈 0.01）, and saturation isothermal remanent magnetization （P 〈 0.01）. This suggested that heavy metals were associated with ferrimagnetic particles in soils, which were attributed to input of traffic emissions and industrial activities. Scanning electron microscopy and energy dispersive X-ray spectra of magnetic extracts of the roadside soils further suggested the llnk between the magnetic signal and concentrations of heavy metals. Thus, the magnetic parameters could provide a proxy measure for the level of heavy metal contamination and could be a potential tool for the detection and mapping of contaminated soils.

Intercostal artery damage and massive hemothorax after thoracocentesis by central venous catheter： A case report

引用

Chinese Journal of Traumatology 2017年第5期20卷 305-307页

作者： bai-qiang li Bo Ye Fa-Xi Chen Lu Ke Zhi-Hui Tong Jie-Shou li Wei-Qin li Department of General Surgery SICU Jinling Hospital Medical School of Nanjing University Nanjing 210002 China

Central venous catheters （CVCs） are widely used in various puncture and drainage operations in intensive care units （ICUs） in recent years. Compared to conventional operating devices, CVC was welcomed by clinicians because of the advantages of easy use, less damage to the body and convenient fixation pro- cess. We came across a patient with severe acute pancreatitis （SAP） who developed cardiac arrest due to thoracic cavity massive bleeding 24 h after thoracoceotesis with CVC. Thoracotomy surgery was carried out immediately, which confirmed an intercostal artery injury. The patient was discharged from hospital without any neurological complications two months later. Here we report this case to remind all the emergency department and ICU physicians to pay more attention to the complication of thoracic cavity bleeding following thoracocentesis conducted by CVC.
