Ohiective To establish an in vitro test system for testing CMV specific immune response. Methods Human embryonic lung fibroblasts(HELF)infected with CMV-AD169 and a mutant strain RV-TB40E-4, respectively, were stained with anti-HLA-A * 0201-PE and then measured for the expression of HLA-A * 0201. The infected HELF were incubated with individual pp65 peptide NLVPMVATV and cultured together with PBMC,then intracellular IFN-γ was tested by flow cytometry(FCM). Results The expression of HLA-A * 0201 was markedly suppressed on AD169-infected fibroblasts, while it was not affected on RV-TB40E-4-infected cells. PBMC showing no response to AD169-infected cells responded significantly to RV-TB40E-4-infected cells. The HELF infected with AD169 and loaded with external peptides induced a significantly stronger response which was the sum of the induced response ratios of the infected HELF and the uninfected HELF loaded with peptides. Conclusion CMV-AD169 downregulates the expression of MHC Ⅰ, while it does not decrease the capacity of cells to present external peptides. RV-TB40E-4,a CMV mutant in which the gene of US2-6/US11 has been deleted, does not affect MHC Ⅰ expression, and therefore represents a more suitable tool to explore CMV-specific immune response.

Although the development of diagnosis and treatment about degenerative scoliosis has improved significantly,it still remains controversial about how to select appropriate surgical methods.The goal of this review is to raise awareness and stimulate attention on the correlation between clinical manifestation and spinal deformity,which is one of the key factors to affect the surgical outcomes on the opinion of more and more researchers in the past 20 years.When an adult spinal deformity is not the source of symptoms and the clinical symptom is outside of curve,symptomatic relief may be provided through limited decompression.If thoroughly decompression,it will be enough to combine with short segment fixation.However,while an adult deformity is the source of symptoms and the clinical symptoms is within the curve,the options are typically limited decompression on the basis of good stability,otherwise,it will be the only consideration of decompression combined with long segment fixation.

Objective To investigate distribution of integrain ?1 in human oocytes and embryos before and after maturation/fertilization,dring the first and second meiosis,in morulae and blastocyst stage. Methods Human oocytes and embryos were stained by anti-integrin ?1 (PharMingen 09351D) and FITC-labeled second antibody (PharMingen 110094D),and observed by confocal microscope. Results Integrin ?1 concentrated in the nuclear area in matured oocytes,zygotes and 2-cell stage embryo,indicating that integrin ?1 might involve in mitosis.Dislike mouse,there was no distribution of integrin ?1 on the well-accepted sperm binding area on the oocytes,indicating that integrin ?1 might not involve in the binding and fusion of human sperm to human oocytes.Conclusion It was first postulated that integrin ?1 might actively involve in the pronuclear fusion process in human in vitro fertilized oocytes.The marker of ectotrophoblasts,polarized distribution of integrin ?1, appeared at the morulae stage.The stronger expression in ectotrophoblasts around the inner cell mass might indicate some specific function of the ectotrophoblasts near the ICM.

A 7?year?old girl presented with a plaque on the left side of the face for 4 years. Skin examination revealed a well?marginated circular firm plaque measuring 6 cm × 5 cm in size on the left side of the face with purulent crusts on the surface, which was nontender to palpation. Histopathologic study showed ulceration and necrosis in some areas in the epidermis, diffuse dermal infiltration of lymphocytes, histiocytes and epithelioid cells with the presence of many neutrophilic granulocytes in some regions. Both periodic acid?Schiff(PAS)staining and acid?fast staining were negative. After 25 days of tissue culture, scotochromogenic Mycobacterium colonies grew, and colony smears showed positive acid?fast staining. The sequences of 16S rRNA and hsp65 genes of the fungal isolate showed 100%and 99%homology with those of Mycobacterium szulgai, respectively. After the treatment with rifampicin, isoniazid and ethambutol, the patient′s condition was improved.
