[Objectives] This study was conducted to verify the field application effect of slow-release nitrogen fertilizer on summer maize in Shajiang black soil area by simultaneous sowing and fertilization, and explore the application scope and nitrogen metabolism mechanism, so as to lay a foundation for fertilizer reduction and efficiency improvement. [Methods] With maize variety Beiqing 340 and sulfur-coated urea as experimental materials, five nitrogen application levels were set, namely, control (C0), slow-release nitrogen 70 kg/hm^(2) (C70), slow-release nitrogen 140 kg/hm^(2) (C140), slow-release nitrogen 210 kg/hm^(2) (C210) and slow-release nitrogen 280 kg/hm^(2) (C280). The phosphorus and potassium fertilizers were all in accordance with the unified standard. [Results] With the application rate of slow-release nitrogen increasing, the nitrogen accumulation in organs increased first and then decreased after tasseling stage of maize. In order to reduce the fertilizing amount and increase efficiency, 210 kg/hm^(2) of slow-release nitrogen fertilizer was the best fertilizing amount for summer maize in Shajiang black soil area. [Conclusions] This study provides reference for fertilizer reduction, efficiency improvement and sustainable development of summer maize in Shajiang black soil area.

Trypsin digestion of spinach chloroplasts not only inhibits light-induced variable fluorescence yield （△F/F0） but also abolishes Mg2+ stimulating effect on △F/F0. If chloroplasts are incubated by Mg2+ prior to trypsin digestion, Mg2+ stimulating ability remains unchanged whereas the enzyme-induced △F/F0 decline itself is not affected. The protective effect of pretreatment of chloroplasts with Mg2+ against trypsin closely correlated with alteration of the net negative charge on the outer surface of the thylakoid membrane by Mg2+. In contrast to this, addition of BSA to the chloroplast digested with trypsin significantly recovers the light-induced variable fluorescence yield but it does not influence Mg2+-induced variable fluorescence change. The recovery effect of BSA incubation is not dependent upon Mg2+ concentration. Also, BSA does not alter the net negative charge on the outer surface of the thylakoid *** results demonstrate the existence of two independent prote

目的:皮肤Rosai-Dorfman病(cutaneous Rosai-Dorfman disease,CRDD)是一种罕见的组织细胞增生性疾病,本文对1例患者资料进行报道,并对既往文献进行回顾性临床病理分析。方法:通过PubMed查询公开发表的英文文献,对该病的人口统计学信息、临床表现、病理特点及治疗等情况进行分析总结。结果:共检索到符合标准的183篇文献,其中包括371例患者资料。分析结果显示男女比例为1∶1.1,平均年龄为46岁,以东亚人(52.3%)最为常见。皮损主要表现为多发的结节、斑块、丘疹,常见于四肢(43.1%)、躯干(36.9%)及面部(27.2%)。该病诊断主要依靠组织病理及免疫组化检查。疾病通常呈慢性良性病程。结论:CRDD好发于东亚人群,具有一定的临床和组织病理学特点,皮肤科医生应该提高对该病的认识。
