Objective To investigate the sleep self-adaptation for Chinese military personnel and the correlations with sleep quality. Methods 857 soldiers completed the Sleep Quality Scale of Chinese Military Personnel (SQSCMP) and the Soldier Sleep Self-Adaptation Scale (SSSAS). Results The average level of sleep selfadaptation of Chinese military personnel was 2.89, below the theoretical midpoint score 3. There were significant positive correlations between the sleep quality and the global level of sleep self-adaptation and its 5 factors ( r =0. 16 ～ 0. 533, P ＜ 0.001 ), except the factor of perceived importance of sleep ( r = -0.027 ). Multiple stepwise regression analysis showed that the major determinants of the sleep quality were the factors of positive attitudes about sleep,the positive self-suggastions on sleep and the ability of anti-disturbance of sleep. Conclusion The positive and appropriate attitudes and beliefs about sleep are of benefit to sleep quality.

Objective To establish the in vitro biofilm model of Laribacter hongkongensis(LH),to analyze the type Ⅰ integron related genes carried by LH and to investigate the mechanism of LH resistance to quinolones.Methods The biofilm forming abilities of LH clinical isolates were determined by Giemsa staining qualitative method and by crystal violet staining semi-quantitative method.The sensitivity of LH to norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin in both planktonic and biofilm conditions were dectermined by broth microdilution susceptibility tests.Type I integron related genes carried in 18 LH strains resistant to quinolone were detected by PCR amplification method.Results The detection results by Giemsa staining demonstrated that 36 strains in 55 LH clinical isolates formed visible biofilm,and the biofilm formation rate was 65.4%(36/55).In the biofilm forming ability detected by crystal violet staining semi-quantitative method,OD560≤0.15 was in 8 strains of LH,0.150.20 in 7 strains respectively.The levels of minimal biofilm inhibitory concentration in norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin to LH were respectively higher than the minimal inhibitory concentration(MIC) in the corresponding floating bacteria(P<0.05).Among 55 strains of LH,18 strains were resistant to quinolones,the resistance rate was 32.7%,and the type I integron in 18 strains of LH carried the drug resistant genes,these drug resistant genes played the drug resistance role in corresponding bacterial strains.Conclusion Drug resistance gene formation and widespread of LH may be associated with type I integron.

Objective To detect the protection induced by HPV-58 L2 11-200 AA in animal, and analyze the relationship between antibody or neutralizing antibody titers and the protection generated by the immunizmg agent. Methods The peptide of HPV-58 L2 11-200 AA was expressed in E. coli and the mice were immunized with the peptide after purification and adsorption with aluminum adjuvant. The protection provided by different immunizing doses was detected in the mouse model against the challenge of the pseud-ovirions of human papiilomavirus types 58. The total antibodies and neutralizing antibody titers of serum were tested with ELISA and neutralization assay against HPV-58 pseudovirus, respectively. The total antibodies or neutralizing antibody titers that can protect the mouse from infection were analyzed. Results The mice can be protected from the challenge with HPV pseudovirus when the immunizing dose was 8 μg. The neutralizing antibody can not be detected in the immune serum by neutralization assay against pseudovirus. The total anti-body level has a corresponding relationship with the protection showed in mouse model. The results of total antibodies detected by ELISA showed that when the titer of total antibodies was ≥25 000, luminescent signal can not be detected and the mice can be protected from pseudovirus infection. Conclusion HPV-58 L2 11-200 AA peptide can protect mice from pseudovirus infection. L2 peptide has a promising perspective to be a candidate vaccine and the level of total antibodies in the immune serum can be used as a surrogate for the evaluation of protection against HPV infection.

Objective:To explore the effect of heparanase (HPSE) on the cell adhesion and invasion ability of hepatoma carcino-ma (HC) cell. Methods:HPSE expressions in human HC cell lines (BEL-7402, HepG2, and HCCLM3) were measured by real-time re-verse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis. Four recombinant miRNA vectors, pcD-NATM6.2-GW/EmGFP-miR-HPSE (pcDNA-miR-HPSE), were constructed and transfected into HCCLM3 cells. Full-length cDNA of HPSE gene was cloned into pIRES2-EGFP vector and transfected into HepG2 cells. Transfection efficiency was observed with fluores-cence microscope. HPSE expressions in transfected cells were measured by real-time RT-PCR and Western blot analysis. Adher-ence ability was determined with microplate reader, and invasion and migration abilities were detected with Transwell chambers. Re-sults:Both HPSE mRNA and protein relative expression levels were higher in the three types of HC cells than those in normal hepato-cyte (P<0.05). HPSE had the highest expression level in HCCLM3 cells and the lowest expression level in HepG2 cells (P<0.05). All five recombinant vectors met the experimental requirements. The transfection efficiencies were 75%-85%. The four miRNA vectors, pcDNA-miR-HPSE, significantly decreased HPSE expression in transfected HCCLM3 cells (P<0.05), and pcDNA-miR-HPSE-1 showed the best interference effect (P<0.05). Plasmid pIRES2-EGFP-HPSE increased HPSE expression in transfected HepG2 cells (P<0.05). After pcDNA-miR-HPSE-1 was transfected, the HCCLM3 cell adherence rate and the cell invasion and migration numbers dropped by almost 50%(P<0.01). After transfection of pIRES2-EGFP-HPSE, the HepG2 cell adherence rate and the cell invasion and migration numbers increased by nearly 40%(P<0.05). Conclusion:Different HPSE vectors could regulate bi-directionally the adher-ence, invasion, and migration abilities of transfected HC cells. HPSE may be related with adherence aside from invasion of HC cell.
