Objective:This article is to study the quality of life and the situation of social support for the elderly in Weifang while analyzing the correlation between them.Methods:This study was undertaken among elderly aged over 60 followning the European five D health scale and Social Support Rating Scale.The results were analyzed statistically.Results:On the living quality of elderly in Weifang,the EQ-SD index was (0.78 ±0.12) and the EQ -VAS index was (76.42 ± 14.67).The result from each scale shows a tremendous health issue among the elderly in Weifang.On the other hand,the situation of social support for the elderly in Weifang appeared optimistic.Still,this situation can be improved in practical supports.Also,there was significant negative correlation between EQ-5D and SSRS (r =0.260,P < 0.05).Results of multiple linear regression show that the subjective support and objective support may enter the regression equation.Conclusion:To conclude,the city of Weifang awaits improvements in aged care and social support for the elderly.Only by this chance the quahty of life of the elderly may be improved.

The bursa of Fabricius (BF) is a central humoral immune organ unique to birds. Four bursal peptides (BP-I, BP-II, BP-III, and BP-IV) have been isolated and identified from the BF. In this study, the immunoadjuvant activities of BPs I to IV were examined in mice immunized with H9N2 avian influenza virus (AIV) vaccine. The results suggested that BP-I effectively enhanced cell-mediated immune responses, increased the secretion of Th1 (interferon gamma)- and Th2 (interleukin-4)-type cytokines, and induced an improved cytotoxic T-lymphocyte (CTL) response to the H9N2 virus. BP-II mainly elevated specific antibody production, especially neutralizing antibodies, and increased Th1- and Th2-type cytokine secretion. BP-III had no significant effect on antibody production or cell-mediated immune responses compared to those in the control group. A strong immune response at both the humoral and cellular levels was induced by BP-IV. Furthermore, a virus challenge experiment followed by H&E staining revealed that BP-I and BP-II promoted removal of the virus and conferred protection in mouse lungs. BP-IV significantly reduced viral titers and histopathological changes and contributed to protection against H9N2 AIV challenge in mouse lungs. This study further elucidated the immunoadjuvant activities of BPs I to IV, providing a novel insight into immunoadjuvants for use in vaccine design.
