Objective To investigate the effect of gut bacteria under chronic colitis on the progression of hepatoma in mice.Methods 22 hepatitis B virus (HBV) -transgenic mice ( male, 8 weeks) were randomly divided into two groups, one group (n =10) was fed the drinking water containing 2% dextran sodium sulphate(DSS)to induce chronic colitis and the control group(n =12)was fed with normal drinking water.In order to investigate the effect of gut microbes, 7 male HBV-transgenic mice(8 weeks, with no detectable hepatoma under microscopy) were cohoused with 4 mice with hepatoma for 16 weeks.Results No significant liver cell damage was observed in the group of the mice fed with 2% DSS-containing drinking water.By the 22 -week old,9 of the 10 mice(90.0%) fed with 2% DSS-containing drinking water, 2 of the 12 mice(16.7%) fed with normal drinking had hepatoma.Both the hepatoma incidence and the tumor numbers in the group of mice fed with DSS-containing water were significantly higher than that in the controls (P =0.002 and P =0.028respetively).Compared to controls, the bacteria family Prevotella (P =0.022) and Anaeroplasma (P =0.014) reduced significantly in the mice with induced chronic colitis.All the mice (n =7) cohoused with the mice with hepatoma had the liver tumor developed at 24 -week-old.Conclusion Alterations of gut bacteria under chronic colitis may promote the development of liver cancer.

Objective To survey the basic situation of trainees, the career awareness, the requirement for training, the problems in training, and the selection to the training institutions for the health management specialist trainees. Method Using the cluster sampling method, the trainees from two health management specialist training institutions in Hunan Province were randomly selected from Oct. 2012 to Jun. 2014, a total of 543 trainees were recruited from tertiary health management specialist trainees of 12 periods training a questionnaire survey was conducted. Result Totally 474 valid questionnaires were received, the effective rate was 87.3%. The trainees were mainly from college or undergraduate settings (366, 77.2%), medical professionals (430, 90.7%). The main purpose of the training was to improve their knowledge and technique. Students' demands in the theory content for health management training mainly included the health monitoring (396, 83.5%), health education and health promotion (384, 81.0%), health risk assessment and risk management (382, 80.6%), health intervention plan formulation, implementation and evaluation (360, 75.9%). Demand for practical skills was mainly for health monitoring (426, 89.9%), health risk assessment (424, 89.5%), health interventions (410, 86.5%), health plan formulation, implementation and evaluation (402, 84.8%), health management in the application of specific people (398, 84.0%), etc. At the same time, most of the students considered that for teaching arrangement equal attention to theory and practice should be paid (320, 67.5%). Conclusion Health management specialist training is still in its infancy in China;establishment and improvement of the relevant policies about health management system and forming a complete standard set of health management specialist training system are imminent.

Objective To review our patients who underwent reconstruction of the defect after combined cranio-maxillo-facial resection in recent years.Methods From January,2005 to January,2011,88 patients underwent reconstruction of the defect after combined cranio-maxillo-facial resection.Different reconstructive techniques were used according to the defect classifications in dura,skull base bone,and facial tissues.For dural defects,no repair (37 cases),primary closure (25 cases),and dural repair (26 cases) were performed,respectively.Dural repair materials included thigh fascia lata (2 cases),temporalis fascia (2 cases),pericranium (1 case) and artificial dural patch (21 cases).Bone reconstruction of the skull base were performed in 61 patients with titanium mesh (57 cases),free iliac bone graft (1 case),free cranial bone graft (2 cases) and Medpor (1 case),respectively.Limited facial soft and hard tissue defects in 44 patients were reconstructed with temporalis system of flaps (36 cases),sternocleidomastoid myocutaneous flap (6 cases),and pterygoid muscle flap (2 cases),respectively.Extensive facial soft and hard tissue defects in 44 patients were reconstructed with free latissimus dorsi myocutaneous flap (26 cases),free pectoralis major myocutaneous flap (12 cases),free anterolateral thigh perforator flap (5 cases cases) and free anteromedial thigh perforator flap (1 case),respectively.Results The overall success rate of 88 flaps was 100％.Cerebrospinal fluid leak was found in 4 patients,wound infection was found in 2 patients,intracranial infection was found in 2 patients,respectively.Six patients with cerebrospinal fluid leak or wound infection were cured by conservative treatment.Two patients with intracranial infection were dead although they underwent salvage surgery.Overall rate of complications was 9.1％,dead rate was 2.3％.Conclusion Successful reconstruction of the defect after combined cranio-maxillo-facial resection can be achieved by watertight dural repair,bone reconstruction of the skull base and well-vascularized tissue covered.Regional flap and free tissue transfer are both preferred reconstructive technique depending on the anatomic site and the extent of the defect.

Objective To explore the influence of excessive PTEN expression to fibroblast cycle and collagen secretion induced by LPS.Methods Normal skin fibroblast in the patient with hyperplastic scar were cultured in vitro.When the primary culture was close to 80% fusion,the digestive passage was performed,cultured to the third generation.LPS(0.5 μg/mL) was adopted to stimulate the third generation of normal skin fibroblasts.Defective adenovirus carrying PTEN gene was transfected to the third passage fibroblasts after LPS stimulation.Flow cytometer was adopted to detect the cell cycle.ELISA method was adopted to detect the secreted collagen amont.Results Excessive PTEN expression could inhibit the increase of G2M cell cycle induced by LPS.LPS stimulation could increase the secretion of collagen in skin fibroblasts,yet excessive PTEN expression could inhibit the secretion of collagen induced by LPS.Conclusion LPS could increase the amont of fibroblasts on G2M cell cycle and secretion of collagen,yet excessive PTEN expression can inhibit the effect.

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.

Objective:To review our patients who underwent cranio-maxillofacial resection in the recent 10 years and explore the indication of the operation. Methods:From 2003 to 2013, 116 patients underwent cranio-maxillofacial resection in our department for the treatment of tumors involving the skull base. Tumors that involved the skull base were divided into 3 types according to skull base invasions shown in the coronal planes of CT and MRI scans. Type 1 tumor was adjacent to the skull base with free bone (n=45), type 2 tumor involved the skull base with intact dura (n=30), and type 3 tumor involved dura with free brain (n=41). All patients underwent cranio-maxillofacial resection by oral and maxillofacial surgeons and neurosurgeons. The defects after cranio-maxillofacial resection were reconstructed immediately with adjacent local or regional flaps (n=62) and free vascularized flap (n=54) according to different de-fects, respectively. Results:Cranio-maxillofacial resection was successfully performed in all patients. No intraoperative complication was found. The overall success rate of soft tissue flaps and free flaps was 98.3%and 96.4%, respectively. Three patients with intracrani-al infection (n=2) and bleeding in the internal carotid artery were dead postoperatively even though they underwent salvage surgery. The overall rate of complications was 14.7%, and the dead rate was 2.6%. Recurrence or distant metastasis was found in 36 patients dur-ing the follow-up period. Conclusion: For the indication of cranio-maxillofacial resection, the balance between tumor resection and postoperative function, survival rate, and quality of life should always be considered. This technique includes the balance between func-tion and form, survival and quality of life, donor and recipient sites, and primary and secondary functions.
