Objective To evaluate the radiographic and CT findings and its diagnostic value of burst fracture of thoracolumbar spine.Methods The features of the frontal and lateral X-ray films and CT in 45 cases of burst fracture of thoracolumbar spine were reviewed.Results Among 45 cases there were type A in 15 cases,type B in 18 cases,type D in 7 cases and type E in 5 cases,three-column injury in 24 cases,two-column injury in 21 cases,the spinal canal narrowing:0?in 5 cases,Ⅰ?in 18 cases,Ⅱ?in 20 cases,Ⅲ?in 2 cases;the line of the posterior rim of the vertebral body being abnormity in 33 cases.Conclusion In examination of thoracolumbar burst fracture,both X-ray films and CT scan are of their own advantages and disadvantages,and they are only in combinodion with each other to improve the accurate diagnostic rate.

9).Renal pathology revealed 3 patients with class Ⅳ, 1 patient with class Ⅱ. Image results showed diffuse pulmonary infiltration lesions. Bronchial lavage fluid was hemorrhage. Three patients recovered after treatment with corticosteroid and intravenous cyclophosphamide therapy. Conclusions Diffuse alveolar hemorrhage is rare serious complications of lupus nephritis. Aggressive immunosuppressive therapy should be started early for a favorable outcome.

Objective To analyze the drug-resistance and distribution of nonferments bacteria infection in our hospital and provide the diagnosis and treatment evidence to doctor.Methods 241 nonferments bacteria strains had been separated from patients of Xinqiao Hospital from July 2006 to Jan 2008. Bacteria identify and drug-resistance test were performed by VITEK-Ⅱanalysis system. The drug-resistance result was determined by MIC with the standard of NCCLS.Results The separate rate in patients of neurosurgery, respiration, orthopaedics were 24.94、23.27 and 10.79 respectively. The main source of specimen are sputum. The drug resistance rate were Imipenem (16.9), Amikacin(29.3), Cefepime (33.9) and Cefazidime(39.1) in 241 nonferments bacteria strains. Conclusion The infection of nonferments bacteria must be recognized by doctors, and it would prompt us to use antibiotic properly.

The partial segment of Marek′s disease virus (MDV) glycoprotein B (gB) gene was amplified by PCR. The segment was cloned into pET-28a vector to obtain the recombinant pET-gB plasmid. The recombinant plasmid was transformed into E.coli BL21,and expressed in very high level as inclusion body after induced with 1.0mmol/L IPTG. The inclusion body was solubilized in urea (8mol/L) . The purified protein was obtained by use of His?Bind affinity chromatography. Mice were immunized i.p. by the purified protein to make the polyclonal antibody. The titer of the antibody by indirect ELISA was 1?10~ -5 . Moreover, the analysis by western blot proved that antibody was specific to the recombinant protein. These works lay a favorable foundation for the study of the immune response by MDV gB.

HEK293 or HeLa cells were transfected by NIRF and, or P53, whole cell extracts andimmunoprecipitates were subjected to SDS-PAGE followed by Western blotting. GST pull-down was carried outto identify the interactions between NIRF and P53. In vitro ubiquitination reaction was carried out to identify P53ubquitinate by NIRF. The results suggested that NIRF could interact with P53 in vivo and in vitro. The results alsoshowed that NIRF could ubiquitinate P53 in vivo and in vitro. The results indicated that NIRF would be a newnegative regulator of P53.

ObjectiveTo explore the regular pattern of TCM beauty prescription.MethodsBased on the ACCESS database platform,we established TCM beauty prescription database and analyzed the information in detailed.ResultsThe total number of beauty prescription in the database was 1821.We focused on analyzing the frequency of medicine application in ancient beauty prescriptions,medicinal diet,acne,chloasma and freckles prescriptions.Statistics showed that dahurian angelica root,indian bread,medlar,honey,black sesame,baical skullcap root,and Chinese angelica were the most commonly used seven kinds of Chinese herbs.ConclusionThe main parts of Chinese medicines for making beauty were those herbs which can nourish yin and blood,supplement yang and qi; and the main parts of Chinese medicine for treating skin diseases were those herbs which can clear heat and detoxicate.

Purpose To compare the CT features of hepatic angiomyolipoma (HAML) and primary hepatocellular carcinoma (HCC) and improve diagnostic accuracy for HAML. Materials and Methods The CT findings of 9 patients with HAML confirmed pathologically and 20 patients with HCC were retrospectively analyzed in terms of lesion location, appearance, size, margin, CT value at each phase, cirrhosis and vessel presence inside tumor. Results Mean CT value on plain scan and at arterial phase on contrast enhanced scan of HAML was significantly lower than that of HCC (t=-2.885, P<0.05;t=-3.307, P<0.01). At portal vein phase, difference in CT value showed no statistic significance (t=-0.293, P>0.05). CT value on plain scan and at arterial phase of both HAML and HCC was not significantly different (t=1.289, P>0.05) whilst that at portal vein phase was significantly different (t=2.516, P<0.05). Central vessels were shown in 7 cases of HAML and 3 cases of HCC, pseudocapsule appeared in 1 case of HAML and 13 cases of HCC with statistical difference (χ2=10.828, 7.219;P<0.01). Conclusion CT scan of HAML reveals the component of fat and presentsfast in and slow outpattern, large shadow of vessel and absence of capsule on contrast enhanced scan, which can be helpful in the differential diagnosis from HCCs.

Objective To explore the causes of rising carbapenem resistance in Acinetobacter baumannii isolates by analysis of the carbapenemase genotypes in A .baumannii .Methods WHONET 5 .4 was used to analyze the changing resistance profile of A .baumannii isolates over years .A total of 320 carbapenem‐resistant A .baumannii isolates were collected from the patients in an intensive care unit from January 2008 to December 2012 .All strains were identified and tested by VITEK 2 for their susceptibility .The metallo‐β‐lactamases genes and OXA carbapenemase genes were investigated by polymerase chain reaction . Results The resistance rate of A .baumannii isolates to meropenem and imipenem increased rapidly from 10 .8% to 80 .4% and from 13 .5% to 83 .5% during the period from 2008 and 2012 .The prevalence of blaOXA‐23and ISAba1‐associated blaOXA‐23genes increased from 25 .0% to 97 .1% .No metallo‐β‐lactamase encoding genes were detected .Conclusions Our results indicate that the rising carbapenem resistance in the A . baumannii isolates in our intensive care unit may be associated with the high prevalence of blaOXA‐23 and IS A ba1‐associated blaOXA‐23 genes .

Phaffia rhodozyma is a good strain for astaxanthin production. An over-producing mutant YB-20-29 was obtained by means of Cs137-?ray and N-methy1-N'-nitro-N-nitrosoguanidin (NTG) treatment. The biomass for this strain by shake culture was 36.32 g/L, the pigment content was 1216.0 ?g/g, an increase of 308% compare to o-riginal strain. The astaxanthin content in broth was 30.9?g /mL. It was a potential strain for astaxanthin over-production.

The expressing cassette, LoxP-CMV-gpt-IRES-LoxP( about 2.9kb), was amplified by PCR from a plasmid, pIRES-gpt, by use of the primers , which contained the loxP sites in 5' terminals, respectively. The loxP sites were designed into primers by the software of Primer primer 5.0. Then the cassette was cloned into the site of BalI in pBUS10 to obtain pUS-gptIRES(L). The sequencing analysis for pUS-gptIRES(L) indicated that two loxP sites with the same direction were correctly inserted into pUS-gptIRES(L).The gpt gene in pUS-gptIRES(L) was replaced by a fragment including the full length GFP gene as well as SV40 poly A sequence to get pUS-GFPIRES(L). pUS-GFPIRES(L) was transiently transfected into CHO cell lines, and then the green fluorescence could be seen, the results showed that GFP gene could be expressed correctly. Moreover, pUS-GFPIRES(L) was transfected into the CEF infected MDV CVI988 strain and recombinant virus was selected by the green fluorescence. The growth curve of virus showed the characteristic of recombinant virus was the same as that of CVI988 in vitro. These results give the basis for further studying the characteristic of MDV in vivo and the application of the Cre/LoxP system to MDV genome.
