The international NGOs have been playing an important role in global health governance, and also represent a channel for countries to exert international influence. However, the Chinese NGOs are not actively in-volved in global health so far. This purpose of this paper is to analyze and show the picture of the social and political context of NGOs in China, to learn from the experience of emerging global health-related NGOs through describing their development, provides a strategy for China to support NGO participation in the global health governance, and to put forward recommendation on how to develop China’s global health NGOs based on experiences from international counterparts. The results of this paper found that China has a better international environment, which is a beneficial opportunity for the country to engage in global health governance. Domestic social NGOs are developing progressive-ly, while they are still being harnessed by political safety considerations, for example being affiliated to public admin-istrative system and policy orientation development. However, this would possibly not obstruct health-related NGOs for its minimal political relevance as it is oriented at professionalism, i. e. specialization, public service attributes and relevance to public governance. Therefore, health-related NGOs can have more support from governments since their number is relatively small, with less foundation ( they are undeveloped) and less participation in international cooper-ation ( they lack international involvement) . International experience indicates that supports from governmental enti-ties represent a backbone of the emerging institutions in the participation into the global health programs. The author suggests that the Chinese government should establish a specific global health development strategy of “prioritizing and improving the whole” and setting up the global development strategy in the county. The government should attach more importance to the government-owned and affiliated and private-capital-supported (social elites) NGOs, guide and subsidize them to the international stage, to engage intensely in global health.

The global health system is undergoing dramatic reforms, which would further bring about signifi-cant changes in key global health stakeholders. As a key actor and decision maker in global health system, NGO owns extensive experiences in global health governance and can provide a systematic experience for China’s participa-tion in global health decision-making as a reference model. This paper aimed at studying the roles of NGOs in the field of global health, the roles which can be summarized in four aspects of advocacy, implementation, support, and community mobilization. In addition, NGOs also developed some potential risks and unexpected impacts on global health governance. As represented by some typical examples, there occurred conflicts of interests between some NGOs and the local governments. A number of local health systems suffered from a considerable brain drain of health personnel to NGOs, especially the health officials and technical staff, which weakened the country’s health workforce and system. The financing model driven by external donors could weaken the influences and capacity of local govern-ments on health planning. As a key member involved in global health, we that suggested China and Chinese NGOs should strategically and rationally borrow their experiences and try to avoid these risks.

The International Foundations have invested large sums of funds to participate in global health gov-ernance and greatly contributed to the promotion of global health. The foundations have extensive experience in the management of global health projects. Based on the nature of the foundation and its structure in the government, this paper compares the management methods of project management, project selection, project planning, project imple-mentation, project follow-up, project evaluation and project completion in two stages of the Gates Foundation and Global Fund. It summarizes the project management features, provided references for China participating in global health governance.

NGOs play an important role in global health governance, and have become the key partners of World Health Organization ( WHO) , European and American governments. The goal of the sustainable development of the United Nations also proposes to strengthen NGOs as global health governance partners. Taking WHO, the Unit-ed States and Britain as case examples, this study reviewed the NGOs positioning and cooperation in their global health strategies. The results found that these entities explicitly define the roles of NGOs and strengthen cooperation in their global health strategies to expand their influence in the field of global health. Results also found that WHO, US and UK have given NGOs a clear positioning, that is, they have strengthened the mutual cooperation ( partner-ships) in the same way of expanding their influence in the field of global health for China’s global health strategy de-velopment referred to those NGOs. Therefore, China should incorporate NGOs into the global health strategy, estab-lish NGOs management and cooperation mechanism and define their roles and make it an important complement to global health. China should also strictly select international NGOs to cooperate with and strive to nurture and support Chinese NGOs to participate in global health programs set by the Government, formulate the cooperation list and neg-ative list for NGOs, and at the same time strengthen the supervision and audit to avoid possible risks of NGOs.

Immobilization of the bacterium Agrobacterium tumefaciens UP-3 was studied in this paper. The results showed that the immobilized cells with the mixture of polyvinyl alcohol (PVA) and sodium alginate (SA) as the immobilizing carrier had good biodesulfurization characteristics; The optimum operation immobilization conditions were 4℃, the total concentration of PVA and SA being 7%(wt), and the concentration of cells being 0.05 g/mL. When DBT addition was 2.7 mmol/L, the DBT degradation of immobilized cells was above 60% while that of resting cells is 13%. The optimum degradation time and temperature of immobilized cells were 5d and 28℃~32℃, respectively.

Objective: To investigate the effect of taurine on learning and memory impairment, cytokines secretion in rats intrahippocampally injected with ?-amyloid (A?) 1-40. Methods: SD rats were randomly divided into control group, A? injected group, taurine (0.3g/kg?d, 0.6g/kg?d) groups. The rats were fed with taurine for 7 days, and then subjected to bilateral intrahippocampus injection of A?1-40 or vehicle. Two weeks later, all rats performed Morris water maze test. The contents of IL-6, TNF-? were checked by way of radio-immunity assay for hippocampus samples. Results: Compared with A?model group, the escape latency and distance were significantly reduced in taurine (0.6g/kg?d) group; the ratio of swimming distance in the target quadrant to that in the whole pool of the probe trial; the content of cytokines of IL-6 and TNF-?in hippocampus were reduced significantly. Conclusion: Taurine can effectively attenuate the cognitive dysfunction caused by A?1-40 in rats. The reduced cytokines content in hippocampus might contribute to this effect.
