Objective To discuss the feasibility of using three-dimensional simulation positioning of puncture route that is sketched according to the transversal and sagittal CT images to design percutaneous vertebroplasty (PVP) plan. Methods A total of 58 patients with 63 diseased vertebral bodies were enrolled in this study. Before PVP, the simulation puncture route was delineated according to the transversal and sagittal CT images, and the simulation puncture parameters were determined by using the software of PACS, in this way the three-dimensional simulation puncturing route was established , and the skin needle entry point as well as the puncture angle were calculated. Unilateral transpedicular approach was used when the simulation puncture route could meet the requirements of unilateral approach. Otherwise , bilateral transpedicular approach would be employed. Three months after PVP visual analogue score (VAS) was used to evaluate the degree of pain relief, and the result was compared with that determined before PVP. SPSS 13.0 software was used for statistical analysis. The estimating data were statistically analyzed with paired t-test and the results were expressed in the form of (x ± s). Results The measurement results showed that significant differences in the puncture angles and skin needle entry points existed between different vertebral bodies. Guided by the preoperatively determined simulation puncture route , PVP was successfully accomplished in all patients. The success rate of single puncturing was 100% (63 vertebral bodies in total). Among 63 vertebral bodies, unilateral transpedicular approach was adopted in 55 and the operation time was (28.5 ± 5.5) minutes, while bilateral transpedicular approach was carried out in 8 and the operation time was (37.5 ± 5.5) minutes. After PVP, complete pain relief was achieved in all patients. No serious complications occurred during the follow-up period. Conclusion Three-dimensional simulation positioning of puncture route that is sketched according to preoperative transversal and sagittal CT images is very useful in precisely determining the puncturing route before PVP, which is very helpful to increase the success rate of single puncture and to improve the procedural safety.

Objective Vaccination is a most effective method for the prevention of severe diseases caused by pandemic influenza and microRNA ( miRNA) mediated gene silencing has offered a novel approach to the construction of new vaccines.Our study aimed to construct a recombinant influenza A ( H1 N1 ) virus with the PB1 gene that carries the target fragment of miRNA Let-7b. Methods After comparing the sequence of the A/Nanjing/108/2009 H1N1 viral fragments with that of Let-7b, we selected PB1 as the optimal gene sequence, inserted the Let-7b binding target gene into PB1, ligated the modified fragments with pDP 2000, and named the recombinant plasmids pDP-mu-PB1 and pDP-sclb-PB1, respectively.We co-transfected the MDCK and 293T cells with the recombinant and other seven plasmids and injected the supernatant into the allantoic cavity of the chickenembryo for virus propagation, followed by detection of the virus by hemagglutination ( HA) assay and measurement of the viral titer by TCID50 .We amplified the viral cRNA by RT-PCR and identified the viruses by agarose gel electrophoresis and nucleotide sequence analysis. Results PB1 was the optimal sequence ( 83 bp -107bp) for the attenuation of viruses.The HA-titers of miRT-H1N1 and scbl-H1N1 were 1∶32 and 1∶64, and their viral loads were 4.68 ×105 and 7.94 ×104 TCID50/mL, respectively.Nucleotide sequence analysis showed the expected fragment in the rescued virus. Conclusion A recombinant strain vaccine was successfully constructed, which has laid the foundation for fur-ther assessment of virulence.

Objective To investigate the correlationship between depressed behaviors and interleukin-1β (IL-1β) in brain tissue in mice which are insensitive to fluoxetine,and to mimic the treatment resistant depression (TRD) in clinical condition.Methods 50 BALB/c mice were randomly divided into Control group (Control),Chronic unpredictable mild stress (CUMS) group and CUMS+fluoxetine group.Mice in Control group were raised ad libitum for 9 weeks,those in CUMS group received CUMS for 9 weeks and those in CUMS+fluoxetine group received 8 weeks' CUMS followed 1 week' s treatment with Fluoxetine(10 mg · kg-1 · d-1).At the end of the 9th week,mice in(CUMS + treatment)group were selected into antidepressant treatment-resistant mice(ATRM) as no remission and Depression Group (DM) as symptoms improved.Body mass test (BMT),open field test (OFT) and forces swim test (FST) were completed respectively in these 4 groups at the endpoint of the experiment,and the brain tissue were extracted after the tests for IL-1β Elisa test.Results (1) BMT:there was no effect of weightgain in ATRM after 1 week' s therapy with Fluoxetine.There was no difference in body-weight between ATRM ((18.56±7.56) g) and CUMS ((19.03± 8.58) g) mice,while compared with Control ((24.56±5.45) g) and DM mice ((20.12±9.17) g) ATRM and CUMS mile's body weight were significantly lower (P＜0.05).(2)OFT and FST:in OFT,there was no significant difference in of horizontal moving distance(F=0.355) either in the frequencies of entering the central zone (F=0.327) among the 4 groups;in OFT,the immobility time of ATRM ((241.50 ± ± 36.55) s) was significantly longer than that in DM ((156.00± 25.47) s) (F=13.573,P＜0.05).(3) Elisa test of IL-1β:the brain' s IL-1β serum level in ATRM ((164.90±46.70) pg/mg) was higher than those in Control ((69.68±6.56) pg/mg)),and DM ((93.09±4.65) pg/mg) (P＜0.01),while no difference with that in CUMS mice.Additionally,the depressive behaviors in ATRM showed its positive correlation with the IL-1β level in CNS (r=0.669,P=0.006).Conclusion CUMS can elicit the refractory depressive symptoms in BALB/c mice to simulate TRD' s characteristic,and the elevated level of IL-1 β within brain tissue may play an important role in the development of TRD.

Objective: To explore the impact of arsenic on cholesterol efflux and the expression of ATP-binding cassette, sub-family A, member 1 ( ABCA1 ), ATP-binding cassette transporter G1 ( ABCG1 ), and scavenger receptor class B member I ( SRBI ) in macrophages, so as to provide the evidence for the mechanism of arsenic induced atherosclerosis. Methods: The human myeloid leukemia mononuclear cells ( THP-1 ), induced by phorbol myristate acetate, and mouse primary macrophages were treated with 0, 0.625, 1.25, 2.5 and 5 μmol/L NaAsO2 for 48 hours. Then the cells treated with 2.5 μmol/L NaAsO2 were changed to arsenic free mediums for 48 hours and collected every 12 hours to analyze the time effect of arsenic. The expression levels of ABCA1, ABCG1 and SRBI were determined by quantitative polymerase chain reaction and western blotting. Cholesterol efflux rates were measured by 3H isotope tracer. Results: Arsenic significantly down-regulated the expression levels of ABCA1 and ABCG1, and cholesterol efflux in a dose-dependent manner. The levels of ABCA1 mRNA decreased by 69% and 72%, the levels of ABCG1 mRNA decreased by 42% and 34%, and the rate of cholesterol efflux decreased by 55% and 59% in THP-1 and mouse primary macrophages cells treated with 5 μmol/L NaAsO2 ( all P<0.05 ). Arsenic had no significant effect on SRBI expression ( all P>0.05 ). Arsenic inhibited ABCA1 expression and cholesterol efflux in THP-1 in a time-dependent manner. Compared with cells before the exposure of arsenic, the level of ABCA1 mRNA and the rate of cholesterol efflux in THP-1 bottomed at 48 hours by 43% and 42%, and gradually recovered when arsenic was removed. Conclusions Arsenic inhibits cholesterol efflux by down-regulating the expression of ABCA1 and ABCG1 in macrophages.

Bel1, a transactivator of prototype foamy virus (PFV), plays pivotal roles in the replication of PFV. Previous studies have shown that Bel1 bears a nuclear localization signal (NLS), but its amino acid sequence remains unclear and the corresponding importins have not been identified. In this report, we inserted various fragments of Bel1 into an EGFP-GST fusion protein and investigated their subcellular localization by fluorescence microscopy. We found that the 215PRQKRPR221 fragment could direct nuclear localization, which accords with the consensus sequence K(K/R)X(K/R) of monopartite NLS. Point mutation experiments revealed that K218, R219, and R221 are essential for the nuclear localization of Bel1. The results of the GST-pulldown showed that the Bel1 fragment with residues 215-223, which bears the NLS, interacts with KPNA1, KPNA6, and KPNA7. This result suggests that KPNA1, KPNA6, and KPNA7 maybe involved in Bel1 nuclear translocation.
