Impact of Africa Regional Food Security Program on Nigerian Farmers： The Case of National Special Program for Food Security

This paper examined the impact of National Special Program for Food Security （NSPFS） on the beneficiaries through a qualitative measurement of the food security status of the beneficiaries. A food insecurity index was estimated to measure the well-being of the beneficiaries as affected by the impact of the program. Beneficiaries were classified into four categories： food secure （41%）, food insecure without hunger （46%）, food insecure with moderate hunger （11%）, and food insecure with severe hunger （2%）. Perceptions of beneficiaries were measured. In conclusion, the program has had a positive impact and enhanced food security among the Nigerian beneficiaries. It is not without its short comings which include delayed and untimely disbursement of funds and lack of output markets, irrigation facilities, production inputs and adequate training on technology know-how. The default rate and number of debtors remain high among beneficiaries. Efforts should be made to correct the short comings to improve the effectiveness of the program and justify the huge financial resources that have been committed.

A new strategy of integrating American culture with English teaching ＆ learning by using VOA Special English feature programs

The paper mainly studies a new way of combining American culture with English language teaching and learning by means of the VOA Special English feature programs. It is based on a 5-year period of teaching practice, experience and reflection. This interactive, innovative, productive and student-centered approach is a far cry from the rigid, old, unproductive and teacher-centered approach of teaching British and American culture without combining language learning and practice as is commonly used here in Chinese colleges. The author also throws some light on how to use on-line teaching resources and how to cultivate independent learning on the part of the students he has worked with.

Is Nationwide Special Campaign on Antibiotic Stewardship Program Effective on Ameliorating Irrational Antibiotic Use in China? Study on the Antibiotic Use of Specialized Hospitals in China in 2011–2012

Summary： With dwindling number of new antibiotics and inappropriate use of antibiotics, the emergence and spread of antibiotics resistance occurs commonly in healthcare institutions worldwide. In China, antibiotics are commonly overprescribed and misused. This study is to assess the effect of the nationwide special campaign on antibiotic stewardship program （ASP） at specialized hospitals in China by investigating prescription information from 2011 to 2012. Data on the hospital consumption and prescription of systemic antibiotics were obtained from four specialized hospitals, including maternity, children＇s, stomatological and cancer hospitals. Systematic random sampling was used to select outpatient prescriptions and inpatient cases. A total of 105 specialized hospitals in 2011 and 121 specialized hospitals in 2012 were analysed. The defined daily doses （DDDs） per 100 inpatient days, the percentage of antibiotic use in outpatient prescriptions, and the percentage of antibiotic use in inpatient eases were used as measurements of antibiotic use. The overall antibiotic use density in the selected hospitals decreased between 2011 and 2012 from 39.37 to 26.54 DDD/100 inpatient days （P〈0.001）. The percentage of antibiotic use in outpatient prescriptions （range： 24.12%-18.71%, P=0.109） and inpatient cases （64.85%-60.10%, P=-0.006） also decreased within the two years. Significant changes were observed among regions and different hospitals within the two years. And antibiotic consumption was correlated with the type and size of specialized hospital in 2012, but not with the regions. This analysis of antibiotic consumption of specialized hospitals allows relevant comparisons for benchmarking and shows that national ASP has improved antibiotic rational use in China. The data will assist policymakers in formulating effective strategies to decrease antibiotic overuse and identify areas that require further work.

涉案企业刑事合规制度的程序法建构

我国刑事法领域有关涉案企业合规改革在实践中取得一定成效,获得了社会各界的广泛认同,须适时总结相关经验并将其转化为法律规范。涉案企业合规的立法化是涉案企业合规改革激励机制真正走向制度化、规范化的根本之路,就程序建构的基本思路而言,增设涉案企业合规特别程序,将整改经验和制度创新在法律上加以确认和补充;重点构建附条件不起诉制度,以分案处理机制实现涉案企业与直接责任人员的罪责相称,以附条件不起诉和相对不起诉的相互区分而又功能互补实现诉前分流;做好检法衔接工作,限制适用合规撤回起诉,发挥法院的程序衔接作用,并且畅通信息共享机制,确保两机关各司其职而又有效衔接,为涉案企业合规改革提供刑事法治保障。

基于STM32特殊路口夜间交通灯设计

在部分老城区的学校、幼儿园、医院等机构门前没有过街天桥,只有人行横道线。为了保证通行效率,这样的路口通常未设置红绿灯,夜间通行存在安全隐患。因此,需要对这样的路口进行交通灯设计。以STM32单片机为核心器件进行电路设计,采用“按键触发”思想,将交通灯分为“常规状态”和“切换状态”,使用Keil MDK软件进行编程,对两种状态分别进行逻辑设计。最后,使用Proteus仿真软件验证设计的有效性。

HMGB1及PD-L1在浸润性乳腺癌非特殊型中的表达及临床意义

目的:探讨高迁移率族蛋白B1(high mobility group box 1,HMGB1)及程序性细胞死亡配体1(programmed cell death ligand 1,PD-L1)在浸润性乳腺癌非特殊型中的表达情况及其与预后的关系。方法:收集257例女性浸润性乳腺癌非特殊型患者的病理及临床资料,采用免疫组织化学法检测浸润性乳腺癌非特殊型及同一患者正常乳腺组织HMGB1和PD-L1的表达情况,分析二者与临床病理参数的关系,并评价其预后价值。结果:HMGB1高表达与肿瘤体积大小、组织学分级、腋窝淋巴结转移、TNM分期以及雌激素受体有关(P<0.05)。PD-L1阳性表达与组织学分级、腋窝淋巴结转移、TNM分期、雌激素受体、孕激素受体、HER2以及分子分型有关(P<0.05)。在预后方面,HMGB1高表达和PD-L1阳性显著影响浸润性乳腺癌非特殊型患者的5年无复发生存率(P<0.05)。结论:HMGB1高表达和PD-L1阳性与浸润性乳腺癌非特殊型患者多项预后不良因素密切相关。HMGB1高表达和PD-L1阳性对浸润性乳腺癌非特殊型患者的术后复发预测具有一定的参考价值。
