OBJECTIVETo identify the etiology of an aseptic encephalitis outbreak (ten cases) in a hospital of Xiamen city from 11 to 17 May, 2011.
METHODSA total of ten patients' throat swabs, anal swabs and cerebrospinal fluid were collected and detected by RT-PCR for pan-enterovirus. The samples containing detectable pan-enterovirus were tested by PCR with genotype-specific general primers located in VP1 region of enterovirus genotype A, B and C (HEV-A, B and C). The PCR products of VP1 segment were purified and sequenced, and phylogenetic analysis was performed. Meanwhile, the pathogens in those samples were isolated in Vero cell culture. Homologous analysis of VP1 sequences were carried out for the cultured virus samples and the original clinical samples to identify the outbreak etiology.
RESULTSAmong the ten cases, seven cases were positive for pan-enterovirus nucleic acid. When tested by genotype-specific PCR, the throat and anal swab samples from those 7 patients were positive with HEV-B VP1 primers. Meanwhile, the HEV-B VP1 segments were sequenced and phylogenetic analyzed, which indicated the seven cases were all infected by enterovirus Echo 30. The sequences from those samples had homology of 95.3% - 97.1% with the epidemic strains in Zhejiang, 2004. Out of the seven cases, the sequences of XM2, XM3, XM4, XM8 throat swab samples and XM3, XM6 throat samples showed 99.4% - 100.0% homology which were different from the sequence of XM1, and the homology was 92.8% - 93.4%. Furthermore, the viruses were isolated using Vero cells from XM1, XM2, XM3, XM4 and XM8 throat swab samples, and the VP1 sequence showed more than 99.9% homology with the original specimens.
CONCLUSIONThe local outbreak of aseptic encephalitis was caused by Echo 30 of enterovirus genotype B, and the epidemic strains may have different genetic background.

By comparing and analyzing the similarity among the international scalp acupuncture, JIAO's scalp acupuncture and ZHU's scalp acupuncture, it is believed that the international scalp acupuncture is a combination of traditional acupuncture and other scalp acupuncture on the basis of channel theory of TCM, and this combination is worthy of discussion. However JIAO's scalp acupuncture lacks scientific evidence. So, the international scalp acupuncture following most contents of JIAO's scalp acupuncture is worthy of discussion.

E2 is a recombinant hepatitis E virus capsid protein including its main antigenic determinants but lacking of the particle assembling domain. P239 was the C-terminal extending protein of E2 and could self-assemble to form virus like particles, which might serve as mimicry of virions both structurally and antigenically. We previously used yeast two-hybrid system to screen proteins interacting with E2 based on a human hepatocyte cDNA library. One candidate was identified as the segment (aa388-437) of cytochrome P450 2A6 protein, which is predominantly expressed in liver and important for metabolization. Some studies have demonstrated that hepatitis virus infection may altered cell metabolic clearance of coumrarin which were rapidly matebolised by CYP2A6. In this research, we demonstrated that the protein interaction between HEV capsid proteins and CYP2A6 by pull-down and co-immunoprecipitation. It was also found that their interaction could decrease the CYP2A6 catalytic activity when p239 was incubated within the CYP2A6-transfected Huh7 cells. These results suggested that CYP2A6 might be related to the pathological process when HEV invaded host cells.

By using Western blot and immunofluorescence assays, the recombinant HEV capsid protein p239 was found specifically attached to the HepG2 cell surface and entered to the cytoplasm with the increase of incubation temperature. Pre-mixture of wild-type HEV with p239 blocked the infectivity of the virus on primary cultured human hepatocytes and HepG2 cells, indicating that p239 and HEV competed the same targeting site on these cells. These data provide evidence that p239 has a similar cell surface structure with wild-type HEV.

OBJECTIVETo compare the clinical outcomes between HLA allele matched (HLA-M) and 1 approximately 2 alleles disparity mismatched (HLA-mis) unrelated allogeneic bone marrow transplantation (URD-BMT).
METHODSThirty-nine patients received HLA-M and 21 received HLA-mis URD-BMT for the treatment of acute leukemia, chronic myeloid leukemia in chronic phase (CP) and myelodysplastic syndromes (MDS) in our hospital between November 1998 and December 2002. Conditioning regimen was Bu 16 mg/kg plus CTX 120 mg/kg, and mycophenolate mofetil (MMF), CsA and MTX were given to prevent aGVHD.
RESULTSThirty-eight of the HLA-M group and 18 of the HLA-mis group were engrafted successfully. The median follow-up duration was 11 (2.5 - 52.0) months for HLA-M group and 9 (2 - 46) months for HLA-mis group. The 3-year probabilities of disease-free survival (DFS) for HLA-M and HLA-mis group were (79.2 +/- 7.1)% and (45.8 +/- 15.5)%, respectively (P < 0.05). Grade II - IV aGVHD occurred in 10 (26.3%) patients in HLA-M group and 6 (33.3%) in HLA-mis group, respectively (P > 0.05).
CONCLUSIONURD-BMT is an effective modality for the treatment of leukemia and MDS. The outcome after URD-BMT can be optimized by matching the HLA-A, B and DR alleles between the donor and recipient.
