Objective To study the clinic characteristics and the treatment of acute pancreatitis ( AP) with and without hyperlipidemia. Methods The clinical data of 99 patients in our hospital from Jan. 2013 and Dec. 2013 were studied. Patients were divided into the hyper-lipidemic acute pancreatitis ( HAP) group and the control group ( AP without hyperlipidemia) . All the patients received standardized clinical AP treatment. The patient’ s condition, plasma biochemical index, treatment outcome, length of hospital stay, cost, and relapse were ob-served. Results The proportion of severe pancreatitis of HAP group (13. 6%) was obviously higher than that of control group (7. 8%). Blood sugar and uric acid of HAP group were significantly higher than that of control group, and the average blood sugar of HAP group reached to 171% of the control group. And the blood amylase of HAP group was only 44. 5% of that in the control group. One year recur-rence rate of HAP group (13. 6%) was significantly higher than that of control group (2. 6%) with a singnificant difference (P<0. 01). Conclusion It is suggested that hyperlipidemia condition has significant relations with the condition, performance and outcome of acute pan-creatitis.

Aim To explore the role of cytoplasmic FKBP52 in AAV-mediated transduction.Methods Murine embryo fibroblasts(MEFs)cultures from FKBP52 wild-type(WT),heterozygous(HE),and knockout(KO)mice were established.The role of FKBP52 in intracellular trafficking of AAV was analyzed by fluorescence-activated cell sorting(FACS)analyses,electrophoretic mobility shift assays(EMSA),southern blot,immunoprecipitations and western blot analyses.Results Conventional AAV vectors failed to transduce WT MEFs efficiently,and the transduction efficiency was not significantly increased in HE or KO MEFs.AAV vectors failed to traffick efficiently to the nucleus in these cells.Treatment with hydroxyurea(HU)increased the transduction efficiency of conventional AAV vectors by~25-fold in WT MEFs,but only by~4-fold in KO MEFs.The use of self-complementary AAV(scAAV)vectors,which bypass the requirement of viral second-strand DNA synthesis,revealed that HU treatment increased the transduction efficiency~23-fold in WT MEFs,but only~4-fold in KO MEFs,indicating that the lack of HU treatment-mediated increase in KO MEFs was not due to failure of AAV to undergo viral second-strand DNA synthesis.Following HU treatment,~59% of AAV genomes were present in the nuclear fraction from WT MEFs,but only ~28% in KO MEFs,indicating that the pathway by which HU treatment mediates nuclear transport of AAV was impaired in KO MEFs.When KO MEFs were stably transfected with an FKBP52 expression plasmid,HU treatment-mediated increased in the transduction efficiency was restored in these cells,which correlated directly with improved intracellular trafficking.Intact AAV particles were also shown to interact with FKBP52 as well as with dynein,a known cellular protein involved in AAV trafficking.Conclusion These studies suggest that FKBP52,being a cellular chaperone protein,facilitates intracellular trafficking of AAV,which has implications in the optimal use of recombinant AAV vectors in human gene therapy.

Two isolation methods for sorting of endothelial progenitor cells (EPCs): from peripheral blood mononuclear cells (PBMCs) and CD133(+) enriched cells were compared, by defining the cell morphology, phenotype, reproductive activities and function in vitro, to provide a reference for clinical application of EPCs. PBMCs from healthy subjects were used either directly for cell culture or for CD133(+) sorting. The two groups of cells were cultured in complete medium 199 (M199) for 7 to 14 days and the phenotypes of EPCs were analyzed by FACS. The proliferation of differentiated EPCs was studied by MTT assay, and the VEGF concentration was measured using an ELISA kit. ECM gel experiment and migration assay were performed in vivo. The results showed that PBMCs produced more colony-forming units (CFU) than CD133(+) enriched cells from the same volume of blood (P<0.01). From day 7 to 14, the two groups showed decreased expression of hematopoietic stem cell markers and increased level of endothelial markers, but CD144(+) cells in CD133(+) group were less than in PBMCs group (P<0.01). PBMCs group secreted more VEGF than CD133(+) group on the day 7 (P<0.01). As compared with CD133(+) group, PBMCs group had more potent potential of proliferation and vascularization in vitro. It was concluded that CD133(+) sorted cells showed a lower capacity of differentiation, secretion, proliferation and vascularization in vitro, suggesting that CD133-negative cells may be a preferential way to get EPCs for clinical therapy.

AIM:To examine the latent membrane protein 1(LMP1)-DNA sequence in nasopharyngeal carcinoma(NPC) and detect mRNA expression of LMP1, EBNA1, EBNA2, and to explore the relationship between EBV infectious status, expression products and NPC carcinogenesis.METHODS: LMP1 DNA was detected in NPC by PCR. Direct sequence was applied to analyze the difference between NPC-LMP1-DNA and B95-8-LMP1-DNA. mRNA expressions of LMP1, EBNA1, EBNA2 in NPC were detected by nested RT-PCR.RESULTS: LMP1 DNA existed in all 47 NPC tissues. Several single nucleotide variations were found between NPC-LMP1-DNA and B95-8-LMP1-DNA. The notable variation was the lost of XhoⅠrestriction site in NPC. Direct sequence showed 30 bp deletion in NPC. The mRNA expressions of LMP1, EBNA1 and EBNA2 in NPC were 76.6%, 80.0% and 74.5% respectively by nested RT-PCR. The expression of EBNA1 in NPC was promoted by Q promoter while the expression of EBNA1 in B95-8 was promoted by C promoter.CONCLUSION: The way of EBV involved in NPC is complex. Latent genes such as LMP1, EBNA1 and EBNA2 as well as early lytic gene BARF1 may all play certain roles in NPC carcinogenesis.
