OBJECTIVETo compare the characterization of hemagglutination and the sequence of HA1 region of the influenza A (H3N2) virus in Zhejiang province and Japan in recent years.

METHODSHemagglutinin antigenic analysis of influenza A (H3N2) viruses which were isolated in Zhejiang province was carried out and to compare their characterization of hemagglutination and the sequence of amino acids in HA1 region with the virus strains from Japan during the same period.

RESULTSThe antigenicity and the amino acid sequence in HA1 region of the virus strains prevalent in Zhejiang in recent years have changed to some extent. Most of the virus strains were lack of hemagglutination reaction to chicken red blood cell and became "O" phase virus strains. The amino acid sequence of HA1 region of the virus strains exhibited only 94.82% of its homology with that of A/Wuhan/359/95 strain. The virus strains of Japan in the same period showed similar characteristics.

CONCLUSIONHA1 gene variation of influenza A (H3N2) viruses was the main cause leading to the spread of influenza in the last years.

Objective To investigate the gene expression profiles of peri-implantation endometrium of high responders during controlled ovarian hyperstimulation. Methods High responders with cancelled embryo-transfer during controlled ovarian hyperstimulation (high responder group, n=4) and healthy fertile volunteers (control group, n=3) were performed endometrial biopsies during peri-implantation. Histologic changes of endometrium were observed by HE staining, genes of differential expression were screened with microarrays Affymetrix U133A 2.0 and identified by Real-time PCR. The biological process analysis was performed by online biological information analysis tool PANTHER. Results The ehdometrium was in mid-secretory phase in control group, while development delay was found in some glandular organs in endometrium of high responder group. Three hundred and sixty-four genes of differential expression were screened, among which 233 were up-regulated genes and 131 were down-regulated genes. OPN, PLA2G2, DPPIV, IGFBP5 and SSAT were identified as endometrial function-related genes, whose Real-time PCR findings were positively correlated to gene signal values detected by microarray(r=0.44, P<0.01). PANTHER analysis indicated that genes of differential expression participated in the biological processes of cytokine signal transduction and immunological regulation. Conclusion Ovarian high response affects the gene expression profiles of peri-implantation endometrium, which may be one of the causes of sub-optimal endometrial receptivity.

The phenotypes of the bone marrow cells in various subtypes of myelodysplastic syndromes (MDS) and its clinical implication were explored. The antigen expression of a panel of antigens expressed in marrow cells from 30 patients with subtypes of MDS was assayed by alkaline phosphatase anti-alkaline phosphatase method. The results showed that the expression of myeloid antigens appeared abnormality, CD13 and CD33, found on granulocyte and macrophage precursors, increased, and CD15 decreased. There were no significant changes for monocytic antigen CD14 and lymphoid antigens CD7 and CD10. CD34 was increased in RAEB/RAEB-t and was not increased in RA/RAS patients. CD71, expressed by erythroblast and proliferative cells, was higher in all subtypes of MDS than that in control group. It is suggested that the bone marrow cells from MDS patients showed abnormality of more than two series of immunophenotypes, detection of immunophenotype in MDS cells might be contributed to the diagnosis and predicting prognosis.

OBJECTIVETo explore the neutralization capacities of different types of human serum to measles virus epidemic strains and vaccine strain.

METHODSNeutralization antibody (NT) to Shanghai 191 and measles virus isolates in 2005 were tested using acute and convalescent serum samples from diagnosed measles patients, children serum samples collected before and after vaccination and serum samples of migrant residents, from 3 different regions. Additionally, animal immune serum referring to vaccine strain and 3 epidemic strains were prepared and used to undergo crossing neutralization test with corresponding strains mentioned-above. Antigenic ratios were calculated.

RESULTSGMT value of NT of after-immune serum to vaccine strains was 50.82,1.86 times higher than that to MVi/ZJ/05/7 (GMT was 27.35), whereas GMT value of convalescent serum to MVi/ZJ/05/7 (GMT was 386.95) was obviously higher than that to vaccine strain (GMT was 1:151.83),and GMT value of migrant residents' serum in 3 regions to MVi/ZJ/05/7 were 2.22-4.17 times lower than that to vaccine strain. Meanwhile,the antigenic ratios between MVi/ZJ/ 99/1, MVi/ZJ/04/1, MVi/ZJ/05/7 and vaccine strain were found to be 4.28,5.24 and 5.66 respectively. Additionally,low NT titers to vaccine strain were found in patients' acute sera and GMT value was over 1:4.

CONCLUSIONThere were obvious differences on neutralization antibody of different types of serum to measles vaccine strain and epidemic strains which indicating the antigenic diversity of epidemic strains had influenced the protective effectiveness of vaccine antibody to epidemic strains. It was of significance to carry on research projects on the antigenic diversity and effectiveness of measles vaccine.
