Research on dual-use of life sciences can promote human health and social development .However,potential harm is also gradually recognized .This article introduces the definition of dual-use life sciences research , major develop-ments and risk samples , trends of development and surveillance , and proposes some considerations in future efforts to strengthen the oversight of dual-use life sciences research .

The 2013 Meeting of Experts from States Parties to the Biological Weapons Convention ( BWC) was held in Geneva from August 12 to 16 in 2013 .This paper reviews the main topics and results of the meeting , analyzes the current situation of biological arms control , and proposes some methods to strengthen implementation .

In recent years , a series of agriculture biosecurity accidents have occurred ,such as mad cow disease , foot-and-mouth disease and avian influenza , which has aroused worldwide , concern over agriculture bioterrorist attacks .This paper comprehensively analyzes the history and impact of agriculture bioterrorism , the current status of international agricul-ture bioterrorism research , and important issues to be taken into account in future efforts to deal with agriculture bioterrorism .

Classification of biological agents is a basic work in biodefense capability building that can help set priorities of biodefense .In this study , we compared and analyzed the Biological Agent Category Lists and the defining criteria used by the Center for Disease Control and Prevention ( CDC) of the United States, the European Union and Russia .We also compared with biological agent category lists for other purposes .

Due to the large population and relatively closed space environment , the subway system is vulnerable to bioterrorist attacks.This paper analyzes the technological response measures against subway bioterrorism in the United States, including Detect to Protect program of Department of Homeland Security (DHS) and PROTECTS program of Depart-ment of Energy ( DOE) .We also put forward some proposals on how to improve China′s capability of prevention of and response to subway bioterrorism .

Biosecurity is defined as effectively responding to biological damage associated with various destructive fac -tors and threats ,maintaining and protecting national interests ,security and public health in the era of globalization .This pa-per analyzes the overall situation of biosecurity capability building since the SARS outbreak in 2003 before concluding that remarkable progress has been made in China , but the gap remains great compared with the need of national security envi -ronment and the capacity building of developed countries .This paper outlines four considcrations regarding the development of biosecurity research strategic planning and offer eight tips on strengthening research on biosecurity technology in China .

Based on situation assessment of the core areas of biosecurity , this paper summarizes three typical features of biosecurity that make it different from traditional safety , abd proposes that biosecurity be regarded as a living-project of a country .A mature and powerful country has to possess sufficient capacity to ensure biosecurity .This study also analyzes the national biosecurity strategyies and practices of the United States ,which has established a national-level capacity building strategy and roadmap with clear objectives ,specified the responsibilities of each federal agency , and regulations linked up with strategic planning .Biosecurity in China is at the crossroads where crisis coexists with opportunity , making it urgent to establish the national biosecurity strategy .

Objective To study the application effect of refined nursing for cesarean section patients simultaneously operated myomectomy.Methods A total of 50 cases with cesarean section simultaneously operated myomectomy in our hospital were divided into study group and control group according to random number table method,with 25 cases in each group.The control group received routine nursing and the study group was given refined care,nursing satisfaction and recovery of the two groups were compared.Results Nursing satisfaction of the study group was 96.0％ (24/25),significantly higher than that of 80％ (20/25) in the control group,the difference was statistically significant (P ＜ 0.05).Anal exhaust,lochia time,hospitalization time and recovery time of temperature in the study group were significantly shorter than the control group,and the difference was statistically significant (P ＜ 0.05).Conclusion Refined nursing applied in cesarean section patients has good nursing effect,and it is conducive to the rehabilitation of patients after surgery.
