Rural health policies are difficult to be implemented at the village level in China.From the perspective of health administrative departments and township health centers, this is due to the lack of the basic conditions of rural health policy and the basic ability of the rural health policy.But from the point of view of village doctors, this is because of the lack of personnel, funding and other embarrassing situations, especially due to crisis and risks are taken to the village clinics and village doctors by the township health centers.In fact, the main reason why the health policy is difficult to land at the village level is that the relationship between the township health centers and village clinics have not been rationalized, as can be specifically seen in weak position of village clinics compared with township health centers.The key to rationalize the relationship between the township health centers and village clinics is to strengthen the development capacity of village doctors, at the same time to get rid of the misunderstanding for village doctors in some of the thinking and policy and strengthen the accountability of primary authorities, and finally open up the relationship between the township health centers and village clinics.

Pathophisiology of Budd-Chiari syndrome is complex and complicated; therefore during the treatment of BCS,both the conditions of inferior vena cava and hepatic veins should be carefully considered. Along with the continuous development of the minimal invasive,reliable efficacy and comparative safety of the interventional therapy,more and more patients are willing to adopt this technology. However,there are still many difficulties that can't be overcomed in the performance. The surgeons,especially the vascular surgeons,should entirely present their knowledge and skill into fulfillment and simultaneously combine with the consideration of the situations of our country to formulate the scientific,reasonable,feasible,safe and efficient treatment plan.

Objective:To compare the effects on the size and distribution of stress of different adhesives on post-core crown restored posterior stump of teeth dentin, to discover reasonable post-crown adhesive material of posterior stump of teeth post-core crown,by three dimensional finite element analyses. Methods:Establish three dimensional finite element models of maxillary first molar post-core crown by CT scanning, Mimics and Abaqus software,which include post core,crown,tooth root, pericementum,alveolar bone and adhesive material. Divide above models into experimental and control group according to the relative adhesive material. Choose three load spots on the occlusal surface of this model, and exert 80N loading strength on each. Then calculate the peak value and distribution mode of Von mises stress,max-principle stress and shear stress. Results:In the different adhesive material experimental groups,the peak value of the stress on the dentin of the composite resin group was lower than those in zinc phosphate groups. Conclusion:On the condition of this experiment,different adhesives have different effects on the peak value and distribution of the stress on the post-core crown restored posterior stump of teeth dentin.

Objective To explore a legal system which helps to provide effective HIV prevention and treatment for commercial sex workers.Method A method of literature review was adopted to analyse the major international literature on the interaction between sex work law and HIV prevention and treatment.Results In an international perspective,there are generally three types of legal frameworks of sex work:prohibitive law,law of regulating sex work through licensing,and decriminalization of sex work.In terms of public health,the prohibitive law drives sex workers to the underground state,hindering HIV/AIDS prevetion and treatment;the law of regulating sex work through licensing is unable to deal with the health problems of the unlicensed sex workers;decriminalization of sex work can not only avoid driving sex workers to the underground state,but can also advance HIV/AIDS prevention and treatment by providing integrated health service and behavioural interventions.Conclusion Among the three legal approaches to sex work,decriminalization of sex work provides the most enabling legal framework for HIV prevention and treatment in sex work community.

BACKGROUND: Many studies have been conducted about cemented and uncemented total hip arthroplasty (THA). However, there are few reports about the differences between cemented and uncemented bipolar hemiarthroplasty in China. OBJECTIVE: To compare treatment effects of cemented and uncemented bipolar prostheses on fracture of femoral neck in the elderly. DESIGN, TIME AND SETTING: Comparative observation. The patients were selected from Department of Orthopaedics, Xi’an Red Cross Hospital from January 2004 to December 2005. PARTICIPANTS: 131 cases of femoral neck fractures (type Garden Ⅲ and Ⅳ) were selected from Department of Orthopaedics Xi’an Red Cross Hospital, including 39 males and 92 females, aged 79 years (ranging 65-98 years); 72 cases of left hip and 59 cases of right hip. METHODS: The patients with various basic diseases were given corresponding treatment before surgery. The operation was performed 3 or 4 days after admission by the same operator. The patients were randomly divided into two groups, who were separately treated with cemented or uncemented prostheses. The patients were followed up for 3 years after operation and the hip function was evaluated by Harris score. MAIN OUTCOME MEASURES: Hip function, Harris score, mortality revision rate, revision rate and complication incidence rate. RESULTS: During follow-up period, 6 in cemented group and 8 in uncemented group died. After 3 month of operation, 43 patients could walk independently, 15 needed walking aid, and 5 only acted on bed in cemented group. In uncemented group, 27 patients could walk independently, and 35 needed walking aid. In hospital, 9 patients of cemented group and 15 of uncemented group had complication. After 3 years of operation, 14 cases underwent revision in cemented group due to prosthesis loosening with revision rate of 23.73%, while only 5 patients underwent revision in uncemented group, including 4 cases of prosthesis loosening and 1 of femur split with a revision rate of 23.73%. One year after operation, there was no statistically significance in Harris scores between two groups. During follow-up period, there was no difference in acetabular abrasion between two groups, but the uncemented group had a higher medullary cavity possession rate. No prosthesis dislocation, heterotopic ossification, or bone dissolving was found. CONCLUSION: There were no differences in hip function between cemented and uncemented bipolar hemiarthroplasty for femoral neck fractures in the elderly during follow up.
