Objective To analyse the features of vertebral hemangioma and inaging diagnostic value of vertebral hemangioma.Methods There were 14 cases with hemangioma proved by clinic and pathology.X-ray plain was performed in all cases,of which 9 cases were performed by CT scan and,only 6 cases were taken MR,and 2 cases had both CT and MR scan.Results The tumors were located in thoracic spine in 10 cases,in lumbar spine in 3 cases and in cervical spine in 1 case.8 cases showed typically fence-like or nest-like;the verterea were irregularly destroyed in 5 cases,of which 2 cases were associated with vertebrea collapsing.According to the features in plain film and CT scan,there were 2 cases misdiagnosed,but 6 cases were all made a correct diagnosis on the base of MR before surgry.Conclusion Typical vertebral hemangima can be diagnosed correctely according to plain film or CT while MR plays an important role in atypical cases.

One influenza H3N2 virus, A/swine/Shandong/3/2005 (Sw/SD/3/2005), was isolated from pigs with respiratory disease on a farm in eastern China. Genetic analysis revealed that Sw/SD/3/2005 was a triple-reassortant virus with a PB2 gene from human-like HIN1, NS from classical swine H1NI, and the remaining genes from human-like H3N2 virus. These findings further support the concept that swine can serve as reservoir or mixing vessels of influenza virus strains and maintain genetic and antigenic stability of viruses. Furthermore, we have successfully established a reverse genetics system based on eight plasmids and rescued Sw/SD/3/2005 through cell transfection. HI tests and RT-PCR confirmed that the rescued virus maintained the biological properties of the wild type Sw/SD/3/2005. The successful establishment of the reverse genetics system of Sw/SD/3/2005 will enable us to conduct extensive studies of the molecular evolution of H3N2 influenza viruses in swine.

AIM:To investigate the ability of a metal complex ammonium tetrathiomolybdate (ATTM) to re-lease H2 S and its cytoprotective effect on an oxidative injury model .METHODS:Released H2 S was absorbed in a reaction flask from ATTM dissolved in the cell medium .Staining with dichlorodihydrofluorescein diacetate or rhodamine 123 fol-lowed by photofluorography was conducted for the observation of reactive oxygen species ( ROS) and mitochondrial mem-brane potential (ΔΨm) levels, respectively.Cell viability and release of lactate dehydrogenase (LDH) from the cells were measured with commercial kits.RESULTS:Similar to another H2S donor GYY4137, ATTM had an ability to release H2S in the cell medium in a dose-dependent manner .Treatment of human skin HaCaT cells with ATTM at concentrations of 25~400 μmol/L didn’ t significantly alter cell viability .Exposure of the cells to ultraviolet rays or a ROS donor H 2 O2 in-creased the intracellular ROS levels .Treatment with 400 μmol/L H2 O2 significantly reduced the viability of HaCaT cells (P<0.01).However, before the treatment with H2O2, pretreatment with ATTM at 100 and 200 μmol/L markedly pre-vented the H2O2-induced cell injury (P<0.01).In addition, the treatment with H2O2 triggeredΔΨm loss (P<0.01) and LDH release from the cells (P<0.01).Prior to suffering from H2O2 injury, the preconditioning with 200 μmol/L ATTM significantly improved ΔΨm levels ( P<0.05 ) and attenuated LDH release from the cells ( P<0.01 ) .CONCLUSION:ATTM is capable of releasing H 2 S and protecting human skin cells against oxidative injury .

To prepare the RNAse-resistant virus particles containing the partial gene fragments of avian influenza virus H5N1 for use as RNA standard and control in RNA virus detection, the genes coding the coat protein and maturase of E.coli bacteriophage MS2 were amplified by PCR and then cloned into prokaryotic expression vector pET32a to construct the intermediate vector pET32a-MS2. In addition, the gene sequences coding hemagglutinin (HA), neuraminidase(NA) and M protein of the H5N1 virus were also cloned separately to the down-stream of plasmid pET32a-MS2, thus constructing the prokaryotic expression vectors pET32a-NS2-HA, pET32a-MS2-NA and pET32a-MS2-M. These recombinant plasmids were then transformed separately to E.coli BL21(DE3) with induction by IPTG. to express the virus-like particles. The virus-like particles observed under electron microscopy were identified by RT-PCR ,while their stability was confirmed by real-time RT-PCR. In this way, the virus-like particles were successively constructed and identified through PCR amplification, enzymolysis identification and sequencing analysis. These virus-like particles observed under electron microscopy appeared to be circular in shape with a diameter of about 50 nm. Their stability was proved to be rather good. From these observations, it is apparent that these virus-like particles can be used as RNA standard and quality control in the detection of avian influenza virus H5N1.
