| 1 | Disinfection byproducts in drinking water and regulatory compliance: A critical review显示文摘消毒副产品(DBP ) 在在很多个国家喝水被调整。这批评评论集中于与 DBP 规章的依从联系的问题,包括为 DBP 分析,出现层次,在各种各样的国家之中的规定比较, DBP 依从策略,和新兴的 DBP 的方法。在中国和美国(美国) 之间的规定比较显示在中国的 DBP 规定基于调整混合物和最大的层次的数字是更紧的。用信息收集规则(ICR ) 数据库的比较评价显示 500 大美国的依从率在中国规定下面浇植物在 US 规定下面是比那低得多的(例如 62.2% 对 89.6% 为全部的 trihalomethanes ) 。先锋移动和其他的 disinfectants 是为 DBP 规章的依从的普通惯例。包括为 haloacetic 酸移动为 trihalomethane 移动和 biodegradation 脱衣的空气,在形成以后的 DBP 移动在 DBP 控制获得了更多的接受。包括 iodinated DBP 和含氮的 DBP,新兴的 DBP 的形成是先锋移动和其他的消毒的非计划中的后果之一。然而,在许多底层,比碳的 DBP,新兴的 DBP 提出了更高的健康风险。 | Xiaomao WANG Yuqin MAO Shun TANG Hongwei YANG Yuefeng E XIE | 2015 | Frontiers of Environmental Science & Engineering2015，9，1： | 8 |
| 2 | Medical expenditures for colorectal cancer diagnosis and treatment: A 10-year high-level-hospital-based multicenter retrospective survey in China, 2002-2011显示文摘Objective: Colorectal cancer(CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan(CNY)using 2011 values.Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stageI cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval(95%CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011(P for trend <0.001), with a cumulative increase of 2.4 times(from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages Ⅰ, Ⅱ, Ⅲ and Ⅳ were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively(P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion(52.6%).Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China. | Jufang Shi Guoxiang Liu Hong Wang Ayan Mao Chengcheng Liu Lanwei Guo Huiyao Huang Jiansong Ren Xianzhen Liao Yana Bai Xiaojie Sun Xinyu Zhu Jialin Wang Bingbing Song Jinyi Zhou Lin Zhu Haike Lei Yuqin Liu Yunyong Liu Lingbin Du Yutong He Kai Zhang Ni Li Wanqing Chen Min Dai Jie He | 2019 | Chinese Journal of Cancer Research2019，31，5： | 8 |
| 3 | Clinical Analysis of 240 Patients with HLA-B27 Associated Acute Anterior Uveitis显示文摘Purpose: To analyze the prevalence of HLA-B27 associated acute anterior uveitis and to identify its clinical features. Methods: A total of 240 patients with HLA-B27 associated acute anterior uveitis,who were admitted to Zhejiang Ophthalmologic Hospital between December 2006 and October 2012, were retrospectively analyzed.The age of onset,sex,affected eyes,HLA-B27 antigen detection,recurrence,joint involvement, and surgical complications were investigated. Results:The average age of onset was 37.0 ±12.0 years and the ratio of male to female patients was 2.4:1. Most cases had alternate unilateral or bilateral involvement. Among all participants, 234 cases (97.5%) were HLA-B27 positive, and 124 cases (51.7%) had spondyloarthropathies (SpA), dominated by 108 cases with ankylosing spondylitis. (AS,45.0%),and mostly seen in male subjects(P<0.05).Six patients were HLA-B27 negative(2.5%)and on statistical significance was noted between male and female patients (P >0.05).A total of 193 cases (80.4%) presented with complications, mainly fibrinous exudation, posterior synechia, and vitreous opacity. Conclusion: HLA-B27 that is associated acute anterior uveitis with a relatively high incidence and recurrence presents with more severe clinical features than does idiopathic acute anterior uveitis,and it often accompanies systemic arthritic diseases. HLA-B27 antibody detection is associated with the diagnosis and treatment of acute anterior uveitis. | Yuqin Wang Xiaoya Lu Yulin Wang Liping Mao Yunfeng Gu Pengfei Chen Meiqin Zheng | 2012 | Eye Science2012，27，4： | 3 |
| 4 | Preparation and optical properties of three-dimensional navel-like Bi_2WO_6 hierarchical microspheres显示文摘Three-dimensional(3D) navel-like Bi_2WO_6(BWO) hierarchical microspheres(HMSs) were successfully prepared using a simple hydrothermal method. The as-obtained BWO samples were characterized by a variety of techniques. XRD result indicated that the as-synthesized samples were well-crystallized orthorhombic phase Bi_2WO_6 structure. SEM observations revealed that the hierarchical microspheres with an average diameter of 2 μm were built from several dozen of nanosheets. UV-vis diffuse reflectance spectrum study revealed that the obtained BWO sample had band gap energy of about 3.3 eV.Photoluminescence(PL) result showed that the sample had weak emission intensity. The BET specific surface area of the BWO sample was about 35.40 m^2/g. The photocatalytic efficiency of the as-obtained BWO was evaluated by the degradation of norfloxacin(NOR) antibiotic. The result showed an about 67%NOR degradation in 8 h. | Qiang Chen Yuqin Mao Naici Bing Yongjin Zou Luping Zhu | 2019 | Chinese Chemical Letters2019，30，3： | 1 |
| 5 | Optimization strategies for Cd and Pb immobilization in soil using meta-analysis combined with numerical modeling显示文摘Chemical immobilization is one of the most effective technologies for remediating sites with heavy metals,but the selection of proper immobilization material and determination of its dose ratio is a challenge that limits the remediation efficiency.In this study,we conducted a meta-analysis of 489 independent observations on the immobilization of heavy metals,in which the immobilization materials were divided into biochar,phosphate,lime,metal oxides,and clay minerals.The statistical analysis of these observations revealed that the material dose ratio was the most important parameter that controlled immobilization efficiency,and the Freundlich adsorption model was successfully applied to calculate the bioavailable heavy metal(BHM)concentration after immobilization.Based on the calculation results,phosphate was the most effective material for Pb immobilization.Lime was the most effective when the initial bioavailable Cd content was 0.1–1 mg kg^(-1),whereas the immobilization effects of lime and phosphate were similar when the initial bioavailable Cd content was 10 mg kg^(-1).In addition to the material dose ratio,initial soil pH(pHi)and organic matter(OM)content were negatively correlated,whereas the fraction of initial BHMs before immobilization(FB)and immobilization time were positively correlated with immobilization efficiency.A numerical model that considered the material dose ratio,pHi,OM,FB,and immobilization time was established to calculate the residual BHM concentration after immobilization.However,these factors only explained less than 45%of the immobilization effect,indicating that other factors,such as the sub-type of the material and modification methods,also affect the immobilization effect.These results could help to optimize the type of immobilization material of heavy metals and its dose ratio in practical engineering applications. | Shengqi QI Huixing JI Dongsheng SHEN Yuqin MAO Jiali SHENTU | 2023 | Pedosphere2023，33，1： | 0 |
