Abstract?AlM: To assess the efficacy and safety of trypan blue and indocyanine green ( lCG ) for continuous curvilineal capsulorrhexis ( CCC ) in mature or hypermature phacoemulsification.?METHODS: A total of 122 eyes of 122 cases with cataracts in mature and hypermature were randomly divided into three groups, trypan blue staining group was 46 eyes of 46 cases as group A, lCG staining group was 40 eyes of 40 cases as group B, control group was 36 eyes of 36 cases as group C. Staining groups were used to 0. 2mL trypan blue or lCG injected into the anterior chamber during operation, respectively. The success rate of CCC, lens posterior capsule rupture and implanted intraocular lens pouch were observed and compared during operation. Anterior chamber inflammation was observed after operation, and compared with the control group to observe and analysis.? RESULTS: The success rate of CCC, implanted intraocular lens pouch were statistically significant difference in trypan blue staining group ( group A ) than that in control group (group C) (P<0. 05). lmplanted intraocular lens pouch was statistically significant difference in lCG group ( group B ) than that in control group ( group C ) ( P<0. 05 ) . The rate of lens posterior capsule rupture was no statistically significant difference in all three groups ( P > 0. 05 ) . Anterior chamber inflammation was no significant difference in the postoperative reaction among the three groups.?CONCLUSlON:The application of trypan blue or lCG for lens capsule staining before CCC in lack of red reflective mature and hypermature cataracts is safe and effective, both results are comparable. lt guarantees a complete CCC and improves the success rate of phacoemulsification.

Objective To evaluate the immune response triggered by an in-house constructed hu-man metapneumovirus multi-epitope antigen ( MEA) in a mouse model .Methods Female SPF BALB/c mice at age 4-6 weeks were used in the study and divided into 7 groups.Mice in the five groups including MEA+oligodeoxynucleotides containing CpG motifs ( CpG ODN) intraperitoneal injection ( i.p.) treatment group, MEA+Alum i.p.treatment group, MEA+Alum+CpG ODN i.p.treatment group, MEA+CpG ODN intranasal (i.n.) treatment group and MEA+Alum+CpG ODN i.n.treatment group were immunized three times on days 0, 14 and 21, and those in the other experimental group were immunized intramuscularly with MEA+Quickantibody5W on days 0 and 21.A control group without treatment was set up accordingly .All mice were sacrificed two weeks after the last immunization .Antibodies including IgG , IgG1, IgG2a and IgA in serum samples were detected by ELISA .MTS assay was performed to analyze the proliferation of lympho-cytes.The cytotoxicity of cytotoxic T lymphocytes (CTL) was measured by LDH assay.Flow cytometry was used to detect T lymphocyte subsets .The cytokines secreted by T helper cells ( Th1 and Th2) were analyzed with Bio-Rad Liquid Chips.Results High titers of IgG, IgG1 and IgG2a antibodies were produced in MEA treated mice except for those in intranasal treatment groups .Serum samples from three groups including the MEA+Alum i.p., MEA+Alum+CpG ODN i.p.and MEA+Quickantibody5W i.m.treatment groups were positive for IgA antibody .The highest titer of IgA antibody was detected in mice from the MEA+Alum+CpG ODN i.p.treatment group, which was 2.15×103.Compared with the control group, significantly enhanced proliferation of lymphocytes was observed in the MEA+Alum i.p., MEA+Alum+CpG ODN i.p.and MEA+Quickantibody5W i.m.treatment groups (P<0.05).Enhanced cytotoxic activities of CTL were observed in mice with ip.and i.m.treatments as compared with those in control group (P<0.05).The levels of CD4+/CD8+T cells were slightly increased in mice from the MEA+CpG ODN i.p., MEA+Alum+CpG ODN i.p. and MEA+Quickantibody5W i.m.treatment groups as compared with those in control group (P<0.05).In-creased secretion of IL-2, IFN-γand Th2-type cytokines including IL-4, IL-5 and IL-10 were detected in mice from the MEA+CpG ODN i.p.treatment group.The MEA+Alum i.p.treated mice showed a slightly increased secretion of IFN-γand significantly increased secretions of IL-4, IL-5 and IL-10.Significantly in-creased secretions of IFN-γ, IL-4, IL-5 and IL-10 were detected in mice from the MEA+Alum+CpG ODN i.p.treatment group.Significantly increased secretions of IFN-γ, IL-5, IL-10 and granulocyte-macrophage colony-stimulating factor (GM-CSF) were detected in mice from the MEA+Quickantibody5W i.m.treatment group.Conclusion MEA together with different adjuvants could stimulate high titers of specific antibodies , increase the proliferation of lymphocytes and enhance the cytotoxic activities of CTL .CpG ODN could bal-ance the Th1/Th2-mediated immune responses , and the balance could be enhanced when using CpG ODN in combination with Alum .A similar effect could be achieved by using the commercial adjuvant Quickanti -body5w.This study has paved the way for further investigation on the development of hMPV epitope vaccines and diagnostic reagents for hMPV as well as the epidemiological study of hMPV .

Objective To dynamically observe changes of IgG, its subclasses and IgE in sera of mice by immunization with mixed recombinant of BCG-Em Ⅱ/3 and BCG-Em14-3-3 vaccine of Echinococcus multilocularis (Era). Methods Forty Balb/c mice of 12-14 week old and 20-25 g weight were intranasally vaccinated by the vaccine, 4 mice were killed randomly by the weight on 0,2,4,6,8,10,12,14,16 and 18 weeks of immunization respectively, sera were gathered from the eyeball to measure IgG, its subclasses and IgE by routine ELISA. Results Levels of IgG, IgG2a and IgG2b in the sera of mice increased obviously on 2-18 weeks, reached the highest level on 10, 4 and 4 weeks respectively, the value was 0.095±0.033,0.022±0.001,0.023±0.003 respectively, as compared with the value on 0 week(0.030±0.013,0.012±0.004,0.013±0.004), the difference being statistically significant(q=2.95,4.87,2.81 respectively, P < 0.01 or P < 0.05); levels of IgG1, IgG3 and IgE in the sera of mice decreased remarkably on 2-18 weeks,came to the lowest level on 4,2,6 weeks respectively, the value was 0.031±0.004,0.136±0.002,0.114±0.002 respectively, as compared with the value on 0 week(0.192±0.007, 0.175±0.013,0.024±0.003), the difference being statistically significant (q =5.16,4.93,5.32 respectively, P < 0.01 or P < 0.05). Conclusion Helper T cell(TH) Ⅰ response is induced in mice by mixed recombinant of BCG-Em Ⅱ/3 and BCG-Em14-3-3 vaccine on early immunization.
