Objective To investigate the relationship between the quality of life and different frequency of sudden death in Yunnan unexplained sudden death disease area.Methods According to the stratified cluster sampling method,728 individuals were selected as the respondents in Heqing County,Eryuan County of Dali Bai Autonomous Prefecture,and in Dayao County of Chuxiong Yi Autonomous Prefecture.According to the random sampling,649 individuals were selected as the control in Yongping County,Dali Bai Autonomous Prefecture.Data of the quality of life (WHOQOL-BREF version) were collected through household surveys.Analysis method including ANOVA,Chi-squared test and multilinear regression were used.Results Compared with the control population,the household income of population in the diseased area was not significantly different statistically (x2 =7.052,P ＞ 0.05).But the differences in education level and chronic disease situation were statistically significant (x2 =35.727,9.810,all P ＜ 0.05).According to the frequency of the sudden death,from one to four,the total scores of the quality of life,the scores of the physiology domain,the scores of the psychological domain,the scores of the environmental domain and the scores of the social relations domain (1 time:54.30,13.74,14.43,11.21,14.91;2 times:54.75,13.86,14.65,11.12,15.10;3 times:52.40,13.21,13.76,11.00,14.41;4 times:49.21,12.15,12.54,9.87,14.64)were all lower than those of the control group (56.03,14.11,14.78,11.88 and 15.26),the differences between two groups were statistically significant (x2 =41.88,25.75,41.07,35.07,8.08,all P ＜ 0.05);the total scores and each domain score of the quality of life were negatively correlated with the frequency of sudden death (the multi-variables regression coefficient were as follows:-1.195,-0.341,-0.356,-0.314,and-0.185,all P ＜ 0.05).Conclusions The quality of life of those who have lived in Yunnan unexplained sudden death area is associated with the outbreak frequency of sudden death.Following increasing of the outbreak frequency of Yunnan unexplained sudden death,the quality of life of the population living in Yunnan unexplained sudden death area has decreased.

Objective To explore the correlations between the social support and the quality of life to them who live in Yunnan sudden unexplained death ward,and provide a scientific basis for taking effective measures to improve the people' s quality of life in the ward.Methods Using the cross-sectional household survey to collect the information of the inhabitants on social support and quality of life by the Social Support Scale,and the WHOQOL-brief Scale.Results The total score of social support,scores of subjective support,objective support in Yunnan sudden death ward ((40.85±8.34),(9.58±3.58),(23.86±4.87)) were lower than those of the control group in the same dimension ((41.82±7.12),(10.47±3.26),(24.51±4.68)) (all P＜0.05).But the score of social support utility in Yunnan sudden death ward (7.41±2.67)was no significant difference between the two groups (6.84±2.56,P＞0.05).After using multiple linear regression to control other confounding factors,such as house-hold income per capita,scores of social support,subjective support,objective support and social support utility were positively correlated with the score of quality of life in Yunnan sudden death ward (the correlation coefficient between the scores of social support and the dimensions related to the quality of life were 0.30,0.11,0.29,0.28,0.36;the correlation coefficient between the scores of objective support and the dimensions related to the quality of life were 0.15,0.05,0.13,0.14,0.19;the correlation coefficient between the scores of subjective social support and the dimensions related to the quality of life were 0.18,0.06,0.21,0.23; the correlation coefficient between the scores of social support utility and the dimensions related to the quality of life were 0.11,0.05,0.10,0.09,0.11 (all P＜0.05).Conclusions The people who live in Yunnan sudden death ward get less social support and social support utility is low,which cause the worse quality of their life.To make this situation better,more social support is necessary to enhance the utilization.

Recombinant expression plasmid of pET-28a (+)-goIL-2 was constructed by inserting the goose IL-2 gene without the signal peptide sequence into the prokaryotic expression vector pET-28a (+), and transformed into the bacterial competent E. coli BL21 (DE3) cells for expression. After IPTG induction, an expected protein band with molecular weight of 15.0 kD was observed on SDS-PAGE gel, recognized by monoclonal antibody against goose IL-2 in western-blotting assay. In the pET-28a (+) expression system, much of the recombinant goose IL-2 (rgoIL-2) was found in inclusion bodies with a portion of soluble protein. The monomer and multimers of soluble goose interleukin 2 proteins were observed in native electrophoresis. The rgoIL-2 proteins were purified by Ni-NTA column under a native condition. The rgoIL-2 soluble protein monomer was isolated by a quick protein isolation and purification system of AKTA FPLC and identified by native PAGE. Bioactivity analysis showed that the rgoIL-2 monomer stimulated the proliferation of goose lymphocytes in vitro. This will establish a basis for further study about the biological function and clinical application of goose IL-2.
