Under active exploration and practice of several generations of organ transpant workers,organ transplantation in China has developed rapidly since 2000 and achieved remarkble results.Techniques of transplantation become mature,and liver transplantation and renal transplantation have reached international advanced level,which benefit massive patients.With high attention and promotion of national government and health administrative departments,structural changes have occurred to source of national organ transplantation to form a China Model.The donation after citizen's death has become the new normal in the organ transplantation in China.Human organ donation work promots the rapid development of transplantation in China,but it also faces challenges of the donor organ shortage and quality improvement.Under the new situation,health,family planning and medical reform work of the national13th Five Year Plan puts forward new requirements on human organ donation and transplantation.Combined with practical work,this article gives a few opinions on how to scientifically further improve the quality and quantity of organ donation and transplantation and directions of future works.

Objective:To evaluate construct validity of China residents health literacy questionnaire and explore the application of confirmative factor analysis(CFA)in health literacy measurements.Methods:CFA was performed on dimension of basic healthy skills in the questionnaire.Latent variable scores and comprehensive score based on factor variance weight were calculated.Comparison among the latent variable scores,comprehensive scores and proportion of knowing was conducted via GLM or Logistic model.Results:Two factors named general capacity and emergency capacity were well fitted(?2=12.12,P=0.356,IFI=0.998,TLI=0.996,RMSEA=0.007).According to comprehensive score the sample qualification rate of basic health literacy was 38.5%(785/2 040),much similar to 38.2%(780/2 040)which is calculated by original item scores.Latent variable score or comprehensive score has more statistical power than that of proportion of knowing in multivariate analysis.Conclusion:CFA is a useful tool and valuable for applying in the field of health literacy measurement and analysis.

It is traditionally thought that interleukins are produced by immunocytes. However, abundant evidence indicates that neuron and neuroglia also produce and excrete interleukins. Brain derived interleukins have reciprocal action with multiple neurotransmitters, and influence animal's behavior, learning and memory. Moreover, brain derived interleukins are involved in Alzheimers disease, depression and so on. Further investigation on brain derived interleukins may improve in understanding the pathophysiology of some related diseases.

BACKGROUND:An efficient blood vessel system has a decisive effect on the survival and function expression of cells in three-dimensional tissues. Therefore it has been a hot research field in tissue engineering to find an appropriate vascularization strategy.
OBJECTIVE:To summarize and discuss the theory and research progress in vascularization strategies.
METHODS:Literature search was performed in PubMed database for English literatures published from 2003 to 2013. The key words are“tissue engineering, vascularization, endothelial cell, scaffold”in English. Then, the papers were further analyzed and reviewed in line with the theme.
RESULTS AND CONCLUSION:A total of 124 papers were searched. At last, 41 papers were selected according to the titles and objectives. Vascularization is the focus and pressing issue in tissue engineering field. There are many vascularization strategies, such as growth factor delivery, cellco-culture, dynamic-culture by bioreactor, scaffolds or decellularized scaffolds. But none of them is recognized as an effective strategy to achieve functional anastomosis with the host and sustain grafts survival for a long time in vivo. It wil be a big breakthrough in the future to co-culture pluripotent stem cells with other stem cells, combine with growth factors and optimize culture conditions for the differentiation in vivo.
