Waste management is becoming a crucial issue in modern society owing to rapid urbanization and the increasing generation of municipal solid waste (MSW). This paper evaluates the carbon footprint of the waste management sector to identify direct and indirect carbon emissions, waste recycling carbon emission using a hybrid life cycle assessment and input-output analysis. China and Japan was selected as case study areas to highlight the effects of different industries on waste management. The results show that the life cycle carbon footprints for waste treatment are 59.01 million tons in China and 7.01 million tons in Japan. The gap between these footprints is caused by the different waste management systems and treatment processes used in the two countries. For indirect carbon footprints, China’s material carbon footprint and depreciation carbon footprint are much higher than those of Japan, whereas the purchased electricity and heat carbon footprint in China is half that of Japan. China and Japan have similar direct energy consumption carbon footprints. However, CO2 emissions from MSW treatment processes in China (46.46 million tons) is significantly higher than that in Japan (2.72 million tons). The corresponding effects of waste recycling on CO2 emission reductions are considerable, up to 181.37 million tons for China and 96.76 million tons for Japan. Besides, measures were further proposed for optimizing waste management systems in the two countries. In addition, it is argued that the advanced experience that developed countries have in waste management issues can provide scientific support for waste treatment in developing countries such as China.

医学专业目录设置对于促进医学学科发展、培养合格的医学人才具有重要意义,在高等院校实施一流学科建设的背景下,健全、科学的专业目录显得尤为重要。为助力我国医学学科发展,本文运用文献分析法梳理了我国医学专业设置现状,系统比较了中国、美国、英国的医学专业目录类别与特点。研究发现,当前我国医学专业目录设置存在专业目录不统一、专业设置数量和内容相对滞后、临床医学专业过早专科化、与住院医师规范化培训专业目录衔接不畅等问题;建议采取统一医学专业目录、丰富学科内涵、体现交叉学科特点、建立规范的医学专业准入和退出机制等举措,推进医学专业目录与国际接轨,为培养合格、规范的医学人才提供路径指引。

In the current study, we assessed and evaluated the costs and benefits of three popular methods of general anesthesia practiced in our department for gynecological laparoscopic surgery in recent years. Sixty adult female patients who underwent elective gynecological laparoscopic surgery under general anesthesia were randomly divided into three groups: group V, group I and group C. In group V, anesthesia was induced intravenously with midazolam, remifentanil, propofol and vecuronium, and maintained with continuous infusion of propofol and remifentanil. In group I, anesthesia was intravenously induced with midazolam, fentanyl, propofol and vecuronium, and maintained with inhaled isoflurane and intravenous bonus of fentanyl. In group C, anesthesia was induced as in group I, but maintained with isoflurane inhalation combined with propofol-remifentanil infusion. All patients received vecuronium for muscle relaxation. Perioperative incidences of complications and total anesthesia costs for patients in all groups were recorded. In addition, postoperative satisfaction of the patients was also noted, and similar outcomes of the satisfaction were reported in all 60 patients. Although there was no statistical significance among groups, the incidence of postoperative nausea and vomiting were higher in group C, and the rates of shivering and the needs for analgesics were higher in group V. Anesthesia costs in group I were the lowest. Therefore, it is concluded that the costs of anesthesia induced with midazolam, fentanyl, propofol, vecuronium, and maintained with isoflurane, fentanyl and vecuronium are cheapest, and there is no significant difference in patients’ satisfaction and safety among the three above-mentioned methods of anesthesia in our department.

本文提出了中国能源发展空间研究的国际比较分析方法。通过比较美国、加拿大、欧洲各国和日本等发达国家能源消费的发展历程发现,尽管达到同等发展水平,不同发达国家的人均能源消费量却差异显著,由此提出了“两类发达国家”的概念,即按能源发展方式可分为“美加模式”和“欧日模式”(后者也可细分为“欧洲模式”和“日本模式”)。然后,从产业、交通、居民生活、商业和服务业4个能源终端消费部门出发,深入剖析了不同模式差异的原因。基于不同发达国家的比较分析研究和我国实际国情,对我国能源发展空间进行了分析,提出我国人均能源消耗在2010年的基础上还有不到一倍的增长空间,并对我国能源的发展提出了几点建议。

越来越多的研究表明,发酵乳杆菌可以用于溃疡性结肠炎的预防和治疗。本研究中,我们从中国不同地区的人群粪便样本中分离出了105 株发酵乳杆菌,并对其基因组草图进行了测序。我们分析了这些菌株的泛基因组和系统发育特征,并对4 个模型菌株(发酵乳杆菌3872、CECT5716、IFO3956 和VRI003)也进行了分析。系统发育分析表明,发酵乳杆菌基因组的进化方向与宿主的地理位置、性别、族群和年龄没有明显的关系。我们挑选了3 株来自不同的系统发育支系的发酵乳杆菌(FWXBH115、FGDLZR121和FXJCJ61)和发酵乳杆菌模式菌株CECT5716,通过构建右旋糖酐硫酸钠(DSS)诱导的结肠炎小鼠模型,
探究这几株菌的抗炎和免疫调节活性。发酵乳杆菌FXJCJ61 和CECT5716 可以通过缓解所有结肠炎相关的组织学指标,保护黏膜完整性,增加肠道短链脂肪酸(SCFA),显著减轻结肠炎,而其他两株菌未能提供类似的保护作用。发酵乳杆菌FXJCJ61 和CECT5716 的抗炎机制与核转录因子kappa-B(NF-κB)信号通路激活以及促进白细胞介素10(IL-10)的产生有关。比较基因组分析结果表明,这些有益发酵乳杆菌的抗炎作用可能与一些特定基因有关。
