OBJECTIVE To compare the three methods on relatedness analysis of Acinetobacter baumannii strains in hospital infection.METHODS Twenty-seven A.baumannii strains caused hospital infection were analyzed by pulsed field gel electrophoresis(PFGE),amplified fragment length polymorphism(AFLP) and multiple gene cluster analysis.RESULTS PFGE analysis showed 19 strains isolated from clinic were with identical clone;AFLP analysis showed 19 strains isolated from clinic were with identical clone;but multiple gene cluster analysis showed 3 clones including 11 strains carried with 8 positive genes(TEM,OXA-23group,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1),6 strains with 7 positive genes(TEM,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1) and 4 strains with 6 positive genes(TEM,ADC,aac(3)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1).CONCLUSIONS The resolving ability of multiple gene cluster analysis is higher than that of PFGE and AFLP in relatedness analysis of A.baumannii strains from hospital infection.

To study the ecological distribution and diversity of endophytic fungi associated with Ferula of medicinal plants in Xinjiang. The endophytic fungi were isolated from roots, stems and leaves of Ferula by microbiology research methods and technology. The endophytic fungi were identified using ITS rDNA sequence analysis and morphology analysis. The composition, diversity and preference of endophytic fungal community were analyzed with Shannon-Wiener biodiversity index (H') and Sorensen coefficient (Cs). A total of 337 strains endophytic fungi were isolated and classified into 38 genera, Alternaria, Aureobasidium and Fusarium were the dominant genera. Among the 337 isolates, the endophytic fungi of F. sinkiangensis were the most, The Shannon-Wiener biodiversity index (H') associated with roots of F. fukanensis was the highest, reached 1.85. The highest Sorensen coefficient ( Cs) was between leaf of F. sinkiangensis and leaf of F. ovina, reached 0.75. From the result, endophytic fungi were widely distributed in six Ferula, there are some notable differences between distribution and composition of the endophytic fungi isolated from different issues and different species of Ferula, show a certain degree of species and tissue preference. The results obtained in this study will provide realistic basis and theoretical basis for further study the secondary metabolites of endophytic fungi associated with Ferula, and the relationship between endophytic fungi and their host plants.

OBJECTIVETo explore the effect of ITF2357, a novel histone deacetylase (HDAC) inhibitor, on the growth, differentiation and apoptosis of acute myeloid leukemic (AML) cells and its mechanism.

METHODSAML cell lines kasumi-1 cells as a model for AML1-ETO positive, and THP1 cells for AML1-ETO negative, the leukemic cells proliferation was analyzed by MTT assay, expression of myeloid-specific differentiation antigen and cell cycle by flow cytometry, cell apoptosis by annexin V staining and flow cytometry. AML1-ETO, acetyl-histone, and caspase protein was analyzed by Western blot.

RESULTS0.5 µmol/L ITF2357 treatment significantly inhibited kasumi-1 cells proliferation, with the 48 h half inhibitory concentration (IC(50)) of 0.1 µmol/L. The initial inhibitory concentration of THP1 cell line was 5 µmol/L. ITF 2357 induced apoptosis of kasumi-1 cells in a time- and dose-dependent manner. A dose-dependent increase in early apoptosis occurred at 24 hours treatment and in late apoptosis at 48 hours treatment by ITF2357. Early apoptosis cells increased from (1.44 ± 1.52)% to (24.51 ± 5.79)%. Late apoptosis cells increased from (2.37 ± 2.8)% to (63.66 ± 1.56)%. ITF2357 induced AML1-ETO degradation by caspase-dependent pathway. 0.25 µmol/L ITF2357 induced a time- and dose-dependent increase in expression of myeloid cell surface protein CD13 and CD15. 5 µmol/L ITF2357 blocked the cells at G(0)/G(1) phase, G(0)/G(1) cells increased from (39.69 ± 6.56)% to (79.2 ± 6.51)% and s-phase cells declined from (60.12 ± 3.29)% to (18.97 ± 6.62)%. Kasumi-1 cells incubated with 0.5 µmol/L of ITF2357, AML1-ETO protein began to decrease at 24 hours and could hardly be detected at 96 hours. ITF2357 induced AML1/ETO degradation through a caspase-dependent mechanism. At the same time, acetylated H3 and H4 increased.

CONCLUSIONLow-dose HDAC inhibitor ITF2357 can effectively inhibit the AML cells proliferation, especially for AML1-ETO positive AML cells. It inhibits Kasumi-1 cells proliferation degradation of AML1-ETO protein expression, blocks the cells at G(0)/G(1) phase, and induces apoptosis and differentiation of the cells.

OBJECTIVETo observe whether deoxyribonuclease I (DNASE1) gene expression and its DNASE1 mRNA expression was detected by real-time polymerase chain reaction and its alternatively spliced transcripts were performed by capillary electrophoresis. An analysis was also made to disclose whether specific single nucleotide polymorphisms (SNPs) haplotype had effects onDNASE1 gene expression and its alternatively spliced transcripts.

RESULTSDNASE1 gene expression was higher in SLE patients than in normal controls (P<0.001), and in patients it was found to be of no relationship with SLE disease activity index score. However, it was increased in female patients. Capillary electrophoresis revealed that the pattern of alternatively spliced transcripts in patients was not the same as that in normal controls. Moreover, it seemed that different SNPs haplotype combination might show different transcript pattern in SLE patients.

CONCLUSIONIn SLE patients, DNASE1 gene expression is abnormal and there are alternatively spliced transcripts different from those in normal controls. DNASE1 gene is a critical factor in the pathogenesis of SLE.

OBJECTIVETo discuss the individual operation standard and safety on the deep puncturing at Tianshu (ST 25).

METHODSThe deep insertion through the peritoneum about 1-2 millimeter was taken as individual standard depth at Tianshu (ST 25) for 39 patients. Using CT cross-section scanning and image surveying, the regression analysis was conducted on the impacts of abdominal circumference (AC,cm) to the peritoneum depth.

RESULTSIt was concluded the formula for calculating the satisfactory depth of individual insertion at Tianshu (ST 25), depth = -0.562 + 0.045 x AC.

CONCLUSIONThe depth of insertion, 1-2 millimeter through peritoneum at Tianshu (ST 25) is safe and feasible in acupuncture treatment, which can be used significantly as the reference and guidance for the assessment of clinical operation and safety on the deep puncturing of the other acupoints on the abdominal region.
