Objective To study the biological characteristics of dendritic cells (DCs) derived from peripheral blood mononuclear cells (PBMCs) of patients diagnosed with syphilis. Methods PBMCs were isolated from 16 patients clinically and serologically diagnosed with syphilis, and from 16 healthy human controls, then cultured with GM-CSF and IL-4. On day 10, the monocyte-derived dendritic cells (MoDCs)of the patients and controls were collected and subjected to the detection of surface molecules by flow cytometry; TpN17 was used to stimulate MoDCs from the controls, the expression of phosphorylated ERK was detected by Westem blotting 20 minutes following the stimulation. Results The positivity rate of CD80 was significantly increased in the patients with syphilis than that in the controls (51.90% vs 33.67,P < 0.05), while no significant difference was observed in the expressions of CD83, CD86 or HLA-DR be tween the two groups (16.53% vs 15.99%, 66.13% vs 59.32%, 91.29% vs 90.51%, all P 0.05). The ex pressions of CD80 and CD83 on the surface of MoDCs were enhanced in a dose-dependent manner after ex-posure to TpN17. The expression of cytoplasmic phosphorylated ERK was observed in MoDC stimulated by TpN17, but not in those without the treatment. Conclusions Antigenic stimulation with Treponema pal-lidum may be a reason for phenotypic abnormality of MoDCs derived from patients with syphilis. TpN17 may stimulate the maturation of DCs through the ERK signal transduction pathway.

BACKGROUND:In total hip replacements, aseptic loosening of uncemented femoral hip prosthesis is the main reason for the failure of artificial hip replacement, the prerequisite of reducing aseptic loosening of prosthesis is to increase fil ing area of femoral prosthesis in femoral cavity.
OBJECTIVE:To obtain the fil ing rate of customized femoral prosthesis in femoral cavity and verify the validity of the methods of CAD/CAM/Robotic integration and the robot grind.
METHODIn this paper, the CT data of femur were used to reconstruct three-dimensional model of femoral cavity. According to this model, a custom uncemented femoral hip prosthesis was designed, then the model of this custom prosthesis was imported into the CAD/CAM/Robotic software to generate cut path. After the cut path was imported into the robotic control er, the custom prosthesis can be fabricated, then this custom prosthesis was inserted into the femoral cavity, and the fil ing result of the custom prosthesis in femoral cavity was analyzed.
RESULTS AND CONCLUSION:The experiment results showed that the customized prosthesis in femoral cavity achieved good fil ing result, the structure of femoral cavity resisted the rotation of the customized prosthesis in femoral cavity, and the customized prosthesis obtained stable fixation in the femoral cavity.

Objective To investigate the association of chromosome 8p copy number alteration (CNA) with postoperative survival of patients with hepatocellular carcinoma (HCC),and to screen for possible target genes in the survival-related CNA (s) in 8p.Methods 187 HCC patients were enrolled into the study,which included 66 patients whose follow-up data were available and the follow-up was 2.6 ~ 73.3 months.High-resolution Agilent 244K comparative genomic hybridization (CGH) and Affymetrix U133 Plus2.0 expression arrays were used to screen for CNAs and gene expression differences in 8p.The associations between CNAs in 8p and survival were analyzed using the log-rank test,Kaplan-Meier survival analysis and Cox proportional hazards models.The gene expression levels between the groups were compared by the Mann-Whitney U test.Results Copy number loss on 8p12 (31/66,47%) was significantly associated with reduced survival rate,and HCC patients with 8p12 loss had a 4.1-fold (95% CI =1.8 ~ 9.4,P < 0.05) increased hazard ratio (HR) for death from HCC,as compared to those without the loss.The mRNA expression levels of the 3 genes in 8p12,including TMEM66,DCTN6,and MAK16,were significantly decreased in HCCs with gene loss than in HCCs without the loss (all P < 0.05),and in non-tumorous liver tissues (all P < 0.05).Conclusion Loss of 8p12 is an independent prognostic marker of unfavorable survival for patients with HCC,and underexpression of genes TMEM66,DCTN6,and MAK16,owing to 8p12 loss,contributed to unfavorable prognosis.

Objective To investigate the relationship between chromosome 6p copy number alterations (CNAs) and postoperative intrahepatic recurrence of hepatocellular carcinoma (HCC);and to screen for the target genes in CNA(s).Methods Array comparative genomic hybridization (CGH) and expression arrays were used to detect CNAs and differences in gene expression, respectively.The associations between CNAs in 6p and HCC recurrence were analyzed using the log-rank test, the Kaplan-Meier curves and the Cox proportional hazards models on 66 patients who had been follow-up for 2.6 ~ 73.3 months.The differentially expression of genes in the potentially recurrence-related CNAs were further evaluated by the MannWhitney U test on 117 HCCs, which included 109 cases with paired array CGH and expression data.Results 6p CNAs were detected in 46 (69.7%) of the 66 HCCs.Of the 8 CNAs with the most frequent recurrence of over 20% , a gain at 6p21.1 was independently associated with a 2.3-fold (95% CI =1.1 ~ 5.1, P < 0.05) increased risk for intrahepatic recurrence and with a more pronounced 3.3-fold (95% CI =1.4 ~ 8.2, P <0.05) risk for early recurrence (≤ 1 year).A panel of 9 genes, including BYSL and RPL7L1 within the documented 6p21.1, were observed to be upregulated in HCCs with 6p21.1 gain when compared with HCCs without (all P < 0.05).A high BYSL expression significantly correlated with a larger tumor size (> 6 cm), vascular invasion and advanced tumor stage (all P < 0.05), and high RPL7L1 expression significantly correlated with vascular invasion and advanced tumor stage (all P < 0.05).Conclusion A gain at 6p21.1 was an independently prognostic marker for intrahepatic recurrence of postoperative HCC, particular for early recurrence, and BYSL and RPL7L1 might be the target genes in the recurrence-related 6p21.1 gain.
