In order to determine the challenge dose of pigeon paramyxovirus type 1 (PPMV-1) inactivated vaccine (S-1 strain). The virus titer of PPMV-1 E5 allantoic fluid (Chuansha strain) was determined using SPF chicken embryos in this research. After inoculating 30-day-old and 120-day-old pigeons with low-HI antibody against PPMV-1 (HI antibody < or =2) with different doses of PPMV-1 (Chuansha strain), the clinical symptoms and histopathological lesions of the challenged pigeons were examined. The results showed that the minimal lethal dose (MLD) of PPMV-1 (Chuansha strain) was 102.5 ELD50, so we determined that 10(5.5) ELD50, which was 1000 times the MLD, could be taken as the challenge dose in the vaccine efficacy test for PPMV-1 inactivated vaccine (S-1 strain).

Objective To investigate the relationship between the polymorphism of adiponectin -11 ,377C> G gene and the risk of coronary heart disease(CHD). Methods A total of 126 CHD patients and 130 healthy controls were enrolled and the frequency of each genotypes and allele gene of adiponectin -11 ,377C > G were detected by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Results (1) The adiponectin gene -11,377C > G sites existed gene polymorphism and the three genotypes were GG, CG and CC. (2) There was statistical difference between CHD group and control group; The G allele frequency of CHD group was significantly higher than that in control group (P < 0.05); The frequency of the C allele gene in CHD group was significantly decreased (P < 0.05). (3) There was no statistical difference of frequency distribution of each genotype and allele gene of adiponectin -11,377C > G between acute coronary syndrome (ACS) group and stable angina group . ( 4 ) The risk of CHD were increased in CHD patients with G allele gene of adiponectin-11,377C > G (P < 0.05). Conclusions The polymorphism of adiponectin -11,377C > G is associated with the increased risk of CHD. The increased G allele gene frequency may represent the increased risk of CHD.

Objective To explore the application status of Nvivo software in qualitative nursing research and compare the difference between overseas and domestic publications. Methods Six databases were searched and finally 159 qualitative nursing articles were analyzed, the information such as year, region, institution, literature source, impact factor, fund support, theme, theory attachment, analytical approach, data collection approach, function utility were used to included. From inception to January 31, 2016. Results It was found that up to 21%(21/100)publications were from Australia, and up to 18.64%(11/59)publications were from Shanghai in the past 15 years. Responsible institutions were mainly college and hospital. 54.24% of these domestic papers had no fund support, and 78 % of these overseas papers had no fund support. Themes of overseas papers were more various than those of domestic. The utility of Nvivo software overseas proved to be more systematic and deeper. Conclusions The quantity and quality of relevant publications increase dramatically in China in recent years, nevertheless, wider and deeper usage of Nvivo function should be explored deeply. Qualitative nursing researchers should take advantage of benefits of Nvivo, build a holistic view and generalize its comprehensive application.
