Objective To evaluate the outcome of combination of intensive preconditioning regimen allo-HSCT with imatinib for treatment of Ph chromosome positive acute lymphocyte leukemia (ALL). Methods Between 2009 and 2010, 8 patients diagnosed as Ph+ ALL received allo-HSCT from HLA identical sibling during complete remission. Imatinib was added into the therapies of 5 patients.Seven patients received the intensive preconditioning regimen based on BuCy2, one patient received the regimen of TBI-Cy. A median of 6. 02 × 108/kg mononuclear cells and 3. 14 × 106/kg CD34+ cells were transfused. GVHD prophylaxis included cyclosporine A and methotrexate. Results All patients were well tolerant to the regimen without serious regimen-related toxicity. The median time of ANC≥0. 5 × 109/L was 15. 5 days, and that of PLT≥20 × 109/L was 19 days. Thirty days after allo-HSCT, all patients got donor engraftment successfully. Among 8 cases, 4 cases presented acute GVHD, 2 developed degree Ⅰ , one developed degree Ⅱ , and one developed degree Ⅳ. Seven patients were alive 100 days after allo-HSCT, 3 of whom presented chronic GVHD. At the end of following-up period, 6 patients were alive, among them, 3 patients were alive without relapse; 3 patients relapsed; Two patients died, one from acute GVHD, and one from leukemia relapse. Conclusion Combined intensive preconditioning regimen allo-HSCT with Imatinib was an effective treatment for Ph+ ALL, but the effect of anti-chronic GVHD of imatinib should arouse certain attention.

OBJECTIVE o facilitate the basic acquaintance with the bioactive lycodine-type alka-loids biosynthetic pathways, we conducted the transcriptome analysis of L. casuarinoides by illumina sequencing.METHODS The plant of L.casuarinoides was collected and was subjected to RNA isolation, cDNA library construction, and illumina sequencing before bioinformatics analysis. After sequencing, the clean reads were obtained for de novo assembly by using Trinity software,and then further processed with TGICL sequencing clustering software to generate unigenes,The unigenes are aligned by Blast X alignment to six public protein database. In addition, all unigenes are functionally annotated by GO, KEGG and characterized putative genes involved in lycopodium alkaloids biosynthesis. RESULTS In total, 124, 524 high-quality unigenes were obtained with an average sequence length of 601 bp. Among the L. casuarinoides transcripts, 61,304 showed significant similarity (E-value<1 e-5) to the known proteins in the public database.Among the total 124 524 unigenes,47,538 open reading frame (ORFs) were predicted. Based on the bioinformatics analysis, all possible enzymes involved in the Lycodine-type alkaloids biosynthetic pathway of L. casuarinoides were identified, including primary amine oxidase (PAO), and Malonly-CoA decarboxylase. In addition, a total of 64 putative cytochrome P450 (CYP450) and 827 transcription factors were selected as the candidates of Lycodine-type alka-loids modifiers. Furthermore, a total of 13 352 simple sequence repeats (SSRs) were identified from the 124, 524 unigenes, of which dinucleotide motifs AG/CT (50.1%), were the most abundant. CONCLU-SION This transcriptome analysis of L.casuarinoides,provides many valuable candidate genes involv-ing in the biosynthesis of novel secondary metabolites but also lays the foundation for genetic diversity analysis via SSRs markers in L.casuarinoides.

Objective To investigate the social cognition and its correlation with social function for attenuated psychosis syndrome (APS). Methods From August, 2014 to December, 2015, 39 patients with APS were recruited as research group. Another 40 normal healthy persons with similar gender, ages, and education levels were selected as control group. The Faux Pas Recognition Test (FPR) and Yoni Task Test were used to evaluate the social cognition, and Social Disability Screening Schedule (SDSS) was used to evaluate the social function. The correlation between FPR, Yoni Task Test and SDSS in the research group was analyzed. Results In FPR test, the faux pas questions score, control questions score and total score of FPR were significantly lower in the research group than in the normal control group (t>2.378, P<0.01). In Yoni Task Test, the cognitive theory of mind total score (Cog), cognitive theory of mind first-level score (Cog1) and cog-nitive theory of mind second-level score (Cog2), and affective theory of mind total score (Aff), affective theory of mind first-level score (Aff1) and affective theory of mind second-level score (Aff2) were significantly lower in the research group than in the normal control group (t>2.341, P<0.01). There was no significant difference in control theory of mind total score (Phy), control theory of mind first-level score (Phy1) and control theory of mind second-level score (Phy2) between two groups (t<1.430, P>0.05). The SDSS total score was signifi-cantly higher in the research group than in the normal control group (t=13.032, P<0.001). In the research group, FPR's faux pas questions score and FPR's total score were negatively correlated with SDSS score (r>0.473, P<0.01); in Yoni task test, Cog's total score and factor scores, Aff's total score and factor scores were negatively correlated with SDSS score (r>0.448, P<0.01). Conclusion Social cognition func-tion in APS is impaired. It is associated with social dysfunction in APS.

Objective To investigate the clinical manifestation of hMPV in infants and young chil-dren presented with acute respiratory tract infection and to identify the molecular character. Methods Na-sopharyngeal aspirates were taken from 310 hospitalized pediatric patients from February to May in 2006, March to April in 2008, and September 2008 to February 2009, and the N gene fragments of hMPV were de-tected by nested PCR amplification. Phylogenetic analysis of 17 strains hMPV N genes was performed. The clinical materials of patients were collected and analyzed. All hMPV-positive samples were examined by multi-PCR for other respiratory viruses. Results Of 310 pediatric patients, 20 (6.5%) were positive for hMPV. The median age of hMPV infected children was 15.0 months(from 16 days to 9 years old), 90% (18/20)of the cases were under 2 years, and 60% were male. Phylogenetic analysis of 17 N gene fragments showed that 11 hMPV strains were A2b subtype. 20 hMPV-positive children were subjected to pneumonia, accounting for 7.1% (20/282) among all pneumonia subjects in this study. The common clinical manifesta-tions of hMPV infected patients were cough, wheezing, shortness of breath and fever. 35% (7/20) needed intensive care, 15% (3/20) were given oxygen therapy. The median length of hospital stay was (11.9 ±4.8) d. No significant seasonal distribution of hMPV was displayed. Two patients were coinfected with ade-novirus and rhinovirus respectively. Conclusion hMPV was an important respiratory pathogen in young children subjected to pneumonia in Tianjin. Three subtypes(A2a/A2b, B1, B2) were prevalent in Tianjin, and A2b was the predominant subtype. No significant difference of clinical characters was observed between A and B type hMPV infected patients.

OBJECTIVETo transfect pcDNA3.1/hTM plasmids containing human thrombomodulin (hTM) gene into human umbilical vein endothelial cells (HUVECs), and investigate the expression of hTM and anticoagulating function of transfected HUVECs.
METHODSHUVECs were transfected with pcDNA3.1/hTM by lipofectin. Expression of hTM mRNA was determined by semi-quantitative RT-PCR, hTM antigen on HUVECs membrane by immunohistochemistry, and activated protein C (PC) in HUVECs by chronometry. By using a semiautomatic coagulator, the effect of the reacting liquid from transfected HUVECs mixed with PC from normal peripheral blood was assayed.
RESULTSAbout 10% HUVECs were transfected by pcDNA3.1/hTM with high-level hTM mRNA and protein expression. Activated PC produced by pcDNA3.1/hTM group, pcDNA3.1(+)/neo group and untransfected group was (2.80 +/- 0.43) microg/ml, (0.75 +/- 0.08) microg/ml and (0.85 +/- 0.11) microg/ml, respectively. APTT was (51.68 +/- 2.73) s, (38.38 +/- 2.44) s, (39.65 +/- 2.39) s, (33.93 +/- 1.73) s and (34.60 +/- 1.86) s and PT was (21.89 +/- 1.66) s, (20.56 +/- 1.74) s, (20.42 +/- 2.04) s, (19.57 +/- 1.36) s and (20.16 +/- 1.35) s in pcDNA3.1/hTM group, pcDNA3.1(+)/neo group, untransfected group, inactivating PC group and control, respectively.
CONCLUSIONSThe pcDNA3.1/hTM plasmid could be transfected into endothelial cells and expressed biologically functioning hTM protein on HUVECs membrane. Activated PC could inhibit intrinsic coagulation pathway obviously with slight effect on extrinsic pathway.

OBJECTIVETo investigate the clinicopathologic features of gastrointestinal stromal tumors (GISTs) and to identify reliable prognostic parameters.
METHODSFifty-nine GISTs were studied by immunostaining of CD117, CD34, SMA, desmin, S-100, bcl-2, and Ki-67. Histopathologic evaluations included tumor size, necrosis, histological growth patterns, mitotic activities and tumor lymphocytic infiltrate. The patients were clinically followed for 2 to 9 years. Univariate, multivariate and correlative statistical evaluations were used to analyze the data.
RESULTSAmong the 59 patients, 40 were alive and 15 died of their tumors at follow-up, the remaining 4 patients died of other causes. Pathological parameters that correlated with prognosis included tumor sizes of more than 5 cm, tumor tissue necrosis, mitotic cell count equal or higher than 5 per 50 high power field, Ki-67 labeling index (LI) equal or higher than 5% and intense bcl-2 immunostaining. Multivariate analysis showed that the mitotic count and Ki-67 LI were independent prognostic indicators. There was a correlation between mitotic count and Ki-67 LI.
CONCLUSIONSMitotic count and Ki-67 LI are the best predictors for a poor outcome of GIST after surgical treatment. Ki-67 immunostaining may substitute mitotic count as a useful prognostic parameter.
