Integration is a critical step in the retroviral life cycle.HIV-1 integrase is involved in the integration of HIV DNA into host chromosomal DNA and appears to have no functionally equivalent in human cells.It has become an attractive and rational target for selective anti-AIDS therapy.A random linear heptapeptides phage display library was panned on the recombinant HIV-1 integrase protein.After five rounds of panning,13 positive phage clones were selected and sequenced.Two consensus peptides(TPSHSSR and HPERATL) were chemically synthesized.The non-radioactive ELISA-based HIV-1 integrase assay showed that the synthetic peptides TPSHSSR and HPERATL were able to inhibit the 3'cleavage or strand transfer activity of HIV-1 integrase to some extent(IC50=(54.56?5.18) ?mol/L,IC50=(28.29?1.32) ?mol/L,respectively) .These heptapeptides could be used for developing new anti-HIV drug candidates,as well as for structural studies of the three-dimensional structure of the entire integrase molecule.

To construct recombinant reporter plasmids containing different Alpha gene segments and Alpha1-TFEB fusion gene and to evaluate the promoter activity of the Alpha gene. Methods:Promoter regions of the Alpha gene were predicted using a software Primer 0.5. Five Alpha gene segments with different lengths and a normal TFEB gene promoter (pTFEB) were amplified via polymerase chain reaction, and recombinant reporter plasmids containing different Alpha gene segments and a normal TFEB gene pro-moter were constructed. Liposome transfection was used to transfect these vectors into the human embryo kidney 293T cells. The pro-moter activity of the Alpha gene was evaluated via luciferase assay. Meanwhile, the recombinant Alpha1-TFEB plasmid was construct-ed and transfected into the 293T cells. The TFEB expression of the recombinant Alpha1-TFEB plasmid was then detected via Western blot. Results: Recombinant reporter plasmids containing different Alpha gene segments and pTFEB were constructed successfully. Compared with the luciferase activity of pGL3-Basic, that of the groups with Alpha1, Alpha2, Alpha3, Alpha4 and Alpha5 significantly increased (P<0.01). The luciferase activity also increased significantly in the groups with Alpha1, Alpha2 and Alpha5 compared with that of the pTFEB group (P<0.01). The TFEB expression of the pGL3-Enhancer-Alpha1-TFEB was significantly higher compared with that of the pGL3-Enhancer group. Conclusion:In t(6;11) translocation RCC, the Alpha gene has a strong promoter activity and it en-hances TFEB expression. The strongest promoter activity region is in Alpha5 with a sequence from 643 bp to 693 bp.

Objective To investigate the effect of low molecular weight heparin on lipid parameters in hemodialysis patients. Methods The trial was double blind, open, controlled and randomized for one year. 35 pre-dialysis patients were divided into two groups: UFH(unfractionated heparin) group(n = 13) and LMWH(low molecular weight heparin ) group(n = 22), UFH or Fragmin according to individual dosage was infused to patients of two groups respectively. The level of serum lipid, lipoprotein, apolipoprotein and activity of lipase were measured at months 0, 6 and 12 of trial. Results Significant increases in serum concentrations of TG, LDL, VLDL, Lp(a) and apo-B were observed, whereas serum concentrations of HDL, apo-Al and activity of plasma LCAT or LDL were decreased in both groups before hemodialysis. As dialysis time went by, in LMWH group, activities of plasma LPL and LCAT elevated; TG concentration decreased; VLDL and LDL were not significantly different compared with that of pre-dialysis, but were statistically different in contrast to UFH group. Conclusion The long-term use of LMWH instead of conventional heparin for anticoagulation during dialysis has beneficial effects on the lipid profile, especially in patients with dyslipidemia.

Objective To investigate the effects of arteriovenous fistula on structure and function of left ventricle in patients with maintained hemodialysis. Methods Levels of hemoglobin, inter-hemodialysis weight increase, blood pressure, diameter and blood flow of the fistula, structure and function of left ventricle were examined before and 12, 24 months after hemodialysis treatment in 44 patients who were divided into group A(low flow group, 900 ml/min) based on the fistula flow at the 24th month. Results Left ventricular end-diastolic diameter (LVDd), interventriculare septal thickness (IVST) and left ventricular mass index (LVMI) increased gradually as the time of hemodialysis going on. The cardio-cheat proportion also increased as well as ejection fraction (EF) and the peak velocity ratio of early and late diastolic period(E/A), especially significantly increased in group B. Cardio-chest proportion , LVDd and LVMI were higher and E/A lower in patients with severe sodium retention than those with mild sodium retention in both groups.
