Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer (NMIBC). NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guérin (BCG) instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.

Irrigation consumes three quarters of global water withdrawals each year. Strategies are needed to reduce irrigation water use, including increasing the efficiency of transfer methods and field application. Comprehensive restoration of soil health, specifically through organic matter amendments, can substantially reduce irrigation demand and increase crop yield. A program to restore severely degraded and desertified soils by incorporating coarse woodchips into the soil successfully increased rainfall capture and elevated soil moisture for several weeks between rainfall events at both Ningxia, north-west China and North Dakota, USA. With addition of fertilizer, woodchip incorporation further increased growth of wheat and alfalfa. Comprehensive soil health assessment of remnant grasslands was used to develop target reference soil profiles by which to guide restoration efforts. Given that most agricultural soils are degraded to some degree, soil health restoration can provide a powerful strategy toward achieving global food and water security.

As the demand for livestock products continues to increase in China, so too does the challenge of managing increasing quantities of manure. Urgent action is needed to control point source (housing, storage and processing) and diffuse (field application) pollution and improve the utilization of manure nutrients and organic matter. Here, we review strategies to improve management at each stage of the manure management chain and at different scales. Many strategies require infrastructure investment, e.g., for containment of all manure fractions. Engineering solutions are needed to develop advanced composting systems with lower environmental footprints and design more efficient nutrient stripping technologies. At the field-scale, there is an urgent need to develop a manure nutrient recommendation system that accounts for the range of manure types, cropping systems, soils and climates throughout China. At the regional scale, coordinated planning is necessary to promote recoupling of livestock and cropping systems, and reduce nutrient accumulation in regions with little available landbank, while minimizing the risk of pollution swapping from one region to another. A range of stakeholders are needed to support the step change and innovation required to improve manure management, reduce reliance on inorganic fertilizers, and generate new business opportunities.

分析了能源消费和经济发展的规律,可再生能源的特点、大量开发利用存在的技术瓶颈和减排二氧化碳的效果,认为我国能源消费总量正处在持续增长期,未来40年内可再生能源不可能成为我国的主要能源,化石能源仍将是我国能源的主体,提出减排二氧化碳、发展低碳经济,要首先重视节约使用化石能源。归纳了我国化石能源开发利用取得的成就和存在的问题,提出了节约使用化石能源的对策,一是确定比较合理的GDP增长速度,建立化石能源消费总量控制指标体系;二是建立化石能源加工利用过程全寿命周期能效及二氧化碳排放的评价方法,通过不断优化提高化石能源利用效率;三是从我国化石能源资源状况出发,研究建立符合国情的低碳现代化生活消费模式;四是充分利用财政税收政策和行政手段鼓励和强制节能;五是加强节约使用化石能源的技术、材料、产品的研究开发和推广应用;六是加大资金投入,实现化石能源的优化利用和节约使用。

本文从经济发展、空间布局、产业特点、基础设施、用水排水、经济环境绩效等方面对长江经济带工业园区的发展进行了分析,基于此识别出园区绿色发展面临的挑战,并提出了园区深化绿色发展的建议。工业园区是长江流域承载制造业集聚的重要产业空间,是实施制造强国战略的主阵地,对沿江各省工业贡献大多超过50%,经济增长主力军和经济稳定压舱石作用显著,因此必须坚持工业园区作为制造强国战略主阵地不动摇。长江沿江工业集聚、园区密布,资源能源消耗及污染物排放量大。园区相关的生态环境问题突出表现为:部分地区的园区生态文明和绿色发展意识尚待提高,创新发展能力亟待强化;沿江工业园区布局及产业结构仍需深入优化,部分园区管理粗放,园区间绿色发展不平衡不充分明显;园区碳排放高,能源基础设施“大少小多”特征锁定碳排放;园区尚未有效控制用水总量及有毒有害污染物削减,水量水质水安全等问题尚未根本性解决。为此,建议从三个方面着力推进沿江园区创新绿色转型,打造长江生态文明建设新高地:一是加强顶层设计,上下游一体推进工业园区绿色发展,建立工业园区绿色发展报告制度;二是综合运用节约、提效、开源等措施深化园区绿色低碳转型,实施能源环境基础设施绿色化、低碳化改造,构建能源基础设施和环境基础设施间能源– 水产业共生体系,建设全生命周期绿色低碳园区;三是精准科学治污,从全过程推进园区水污染防治、水生态环境保护和可持续水管理,促进化工围江迈向人水和谐。
