Objective To investigate the attitudes of medical students regarding to organ donation compensation.Method A self administered questionnaire was distributed to 600 medical students selected randomly from two medical universities in China between January 2013 and January 2014.The questionnaire included demographics and core questions related to medical student's attitudes regarding organ donation compensation.Result A total of 600 questionnaires were distributed and 592 valid responses were received,including 150 doctoral students,143 master students and 299 undergraduate students.In all,69.8％ of medical students believed that compensation for organ donor was essential.Nearly 60.5 ％ believed financial compensation would increase the rate of organ donation but would not tarnish the behavior of organ donors (64.7％).At the same time,over 70％ of medical students believed that financial compensation would increase the number of living organ donation.With regarding to the ways of compensation,most of the students (80.4％) were in favor of priority on waiting list.Reducing or free of hospitalization costs (50.4％) and increasing the reimbursement ratio of medical insurance (41.8％) were also the acceptable compensation ways to medical students.Conclusion Most of medical students believe that it is essential to give compensation to organ donors.Enjoying the priority on waiting list,reducing or free of hospitalization costs and increasing the reimbursement ratio of medical insurance are the reasonable incentive methods.

BACKGROUND:By analyzing the current difficulties faced by human organ transplantation and social factors which lead to organ transplant donor shortage in China, people are found to be generaly lack of knowledge about organ transplant and donation process. OBJECTIVE: To make a tentative probe into the construction of organ donation social mission system on four aspects, namely the importance, ethical principles, current situation and countermeasures, and to provide scientific advice and information for organ donation publicity and education. METHODS: Articles about organ donation and organ transplantation were retrieved from CQVIP, CNKI, Wanfang, PubMed, Medline System from January 2005 to November 2014 with the key words of “organ donation, organ transplantation, shortage of donor, body donation, education system” in both Chinese and English. After secondary manual retrieval of organ donation coordinator, literature were included if they involved organ donation coordinator and organ donation and transplantation related policies and regulations. This paper put forward countermeasures for the construction of human organ donation social mission system in China based on the literature induction. RESULTS AND CONCLUSION:This paper describes the necessity of organ donation education system, systematicaly analyzes the existing problems for current organ donation education problems and ethical principles that should be folowed, and explore the construction strategy of human organ donation social mission system in China. The way to relieve tension of organ transplant donor and expand donor sources is to win broad support and understanding of citizens, which can ensure the sustainable development of organ donation work. So, it is very important to build the human organ donation social mission system.

Objective:To retrospectively evaluate the prognostic risk factors of patients with gallbladder carcinoma and the effect of normal prognostic nutrition index (PNI) on the survival. Methods:We retrospectively analyzed 63 patients with gallbladder carcino-ma treated in our hospital between January 2008 and December 2012. The independent prognostic factors of the patients were calculat-ed by the Cox proportional hazards model. The benefit of normal PNI status on the prognosis was further explored in the patients using survival analysis. Results:Lymph node metastasis, PNI≤50, squamous carcinoma, liver invasion and choledoch invasion were the risk factors of overall survival (OS) in the univariate analysis, while only lymph node metastasis (HR=4.495, 95%CI 2.380~8.488, P<0.001) and PNI(HR=0.195, 95%CI 0.098~0.389, P<0.001) were the dependent influential factors of the prognosis and OS in the multi-variate analysis. The effect of PNI on OS was even more statistically significant different in the younger patients (≤65y) than in the el-der (>65y) (younger group:P=0.011;elder group:P=0.078). Conclusion:The gallbladder carcinoma patients with normal PNI status (>50) have better OS compared to the patients with PNI≤50, with statistical differences between the two. And it is more significant in the patients of the younger group (≤65y), comparing with the elder group. PNI could be taken as a potential prognostic evaluation factor for the gallbladder carcinoma patients and can provide a more comprehensive evaluation of patients' conditions to clinician.

Objective To explore the interference situation of several diseases in the detection of treponema pallidum antibody by chemiluminescence method.Methods One hundred and ten samples of 9 kinds of different infectious diseases and 200 clinical random samples were collected.Three hundreds and ten samples were simultaneously detected by using the Abbott ARCHITECT i2000 automatic chemiluminescence immunoassay analyzer and matched reagents,and the Roche E602 automatic chemiluminescence instrument and its matching reagent.The samples of inconsistent results were confirmed by the gelatin particle agglutination test (TPPA).Results There were 5 samples with inconsistent results detected by two instruments,5 samples confirmed by TPPA were negative,and 4 cases were the samples of multiple myelome.Conclusion (1)Abbott ARCHITECT i2000 and Roche E602 have a good consistency in detecting treponema pallidum antibody;(2)for the patients of multiple myeloma,the interference may exist in detecting treponema pallidum antibody by chemiluminescence method,which may cause false positive results and needs to be vigilant in our daily work.
