To observe the changes in hemorheology, endotoxin and TNF ? in blood after hemoperfusion(HP) with adsorbent immobilized polymyxin B (PMB) on sepsis in rats. Wistar rats were randomly divided into three groups:LPS+HP+PMB,LPS+HP and LPS. All the rats received intravenously injection of lipopolysaccharide (LPS, Escherichia coil O111:B4,1mg/kg). Plasma of the rats in the group of LPS+HP+PMB was passed through a column containing sepharose coated activated charcoal immobilized polymyxin B at the 4th hour after LPS injection. The treated plasma was transfused bak after being mixed with blood cells. In LPS+HP group, the column did not contain immobilized polymyxin B. The animals of LPS group received LPS only. Quantitative endotoxin determination in blood was done with limulus amebocyte lysate test,TNF ? of the plasma assayed with ELISA, and hemorheology parameters were also observed after hemoperfusion. In LPS+HP+PMB group, the concentration of plasma was significantly decreased after hemoperfusion, but it was still significantly higher than the baseline value, and there was a decrease of blood cell ratio after hemoperfusion. The results suggest that specific adsorbent could remove endotoxin in the circulation and improve hemorheology.

As a novel Golgi protein,GOLPH2 expression is associated with maintaining the structural integrity of the Golgi apparatus.As an oncoprotein,GOLPH2 expression is associated with malignant biological behavior of cancer cells.Important roles of GOLPH2 in the tumorigenesis and metastasis make it become a new target for tumor diagnosis and treatment.

Objective To study the characteristics of mesenchymal stem cells(MSCs)derived from chronic myelogenous leukemia(CML)patients' bone marrow and examine their hematopoiesis support in vitro.Methods MSCs from CML were obtained and cultured.Immunophenotype and in vitro differentiation capacities were investigated.Moreover,the Ph chromosome and bcr/abl gene of CML derived MSCs were detected.The expression of cytokines was detected by RT-PCR,and hema- topoiesis support of MSCs in vitro was detected by long-term bone marrow culture and the methylcel- lulose progenitor assay.Results CML derived MSCs showed a typical fibroblast like morphology. They were positive for CD29,CD44 and CD105,while negative for CD14,CD31,CD45,CD34 and HLA-DR.Under suitable conditions,CML derived MSCs could differentiate into osteoblasts and adi- pocytes.Further,CML derived MSCs showed a normal choromosome,and did not express bcr/abl gene.At last,they expressed hematopoiesis cytokines and possessed ability of hematopoiesis support in vitro.Conclusion There are MSCs with multidirectional differentiation potential in CML bone mar- row and they possess the ability of hematopoiesis support.

To construct human antibody repertory with phage display technology. Total RNA was extracted from peripheral blood lymphocytes (PBL) of clinical glioma patients and subjected to reverse transcription PCR. Variable region genes(V ? and V H genes) were amplified from the cDNA using nested polymerase chain reaction. V ? gene library was first constructed and attached to the Linker which could specially connect V ? gene and V H gene, then V H gene was cloned into V ? gene library to build ScFv repertoire. Positive colonies were selected randomly and sequenced. The results implied that amplified human V ? gene and V H gene could be derived from PBL of clinical glioma patients. ScFv phage antibody gene repertoire in about 2?10 6 capacity was successfully constructed. The sequencing indicated that the cloned genes encoded variable regions of heavy chains of human antibody and were highly homologous with human kappa heavy chain group III of Kabat's database. Then human antibody repertoire was successfully constructed with phage display technology. The present study can be used as a foundation for succeeding screening of specific antibody against human glioma.

Objective To summarize ultrasonograph changes and to investigate the diagnositic value of ultrasonography in pa‐tients with thrombophlebitis in superficial dorsal vein of penis .Methods The ultrasonograph finding and clinical data in 19 patients with thrombophlebitis in superficial dorsal veins of penis diagnosed by clinic were retrospective analyed .Results Compared with normal volunteers ,the internal diameter of patients′venae dorsales penis superficiales were significantly widened (P<0 .01) .Low level echoes were found in superficial dorsal vein of penis and showed strip ,arborization ,semiring and circular shape .It mainly hap‐pened in root segment(63 .2% ,12/19) ,and coronary sulcus was the second one(26 .3% ,5/19) .There were no significant difference in left and right side (P>0 .05) .Conclusion Ultrasonograph was a practicable way to examine dorsal veins of penis and an effec‐tive way for the diagnosis of thrombosis ,which could accurately diagnose thrombophlebitis in superficial dorsal veins of penis .

AIM:To explore the effects of transforming growth factor-α( TGF-α) in the monoclonal formation , proliferation, migration and adhesiveness of human endothelial progenitor cells ( EPCs).METHODS: The isolated and cultured EPCs were treated with various concentrations of TGF-α(final concentrations of 1, 5, 10μg/L, respectively).At the same time, the PBS control and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) group (10μg/L TGF-αplus 1∶1 000 EGFR-TKI) were set.The effects of TGF-αon monoclonal formation , proliferation, migration and adhesiveness of EPCs were determined by clone formation experiment , thiazolyl blue tetrazolium bromide (MTT), EdU, Transwell and adhesion assays , respectively.The expression of epithelial growth receptor (EGFR) and vascular endothelial growth factor ( VEGF) were measured by Western blotting .RESULTS:Different concentrations of TGF-αall significantly induced the monoclonal formation , proliferation, migration and adhesiveness of EPCs (P<0.01), which were inhibited by EGFR-TKI.The results of Western blotting showed that TGF-αalso induced the expression of EGFR and VEGF with a cer-tain concentration effect ( P<0.01) .CONCLUSION:By combining with EGFR induced the expression of VEGF , TGF-αsignificantly promotes the related cell function of monoclonal formation , proliferation, migration, adhesiveness in EPCs.
