BACKGROUND:Recent studies have found that adipose mesenchymal stem cells can inhibit immune responses of T cells, B cells and dendritic cells. But it is unclear whether adipose mesenchymal stem cells are able to regulate the immune responses of macrophages. OBJECTIVE:To observe the expression of interleukin-6 and tumor necrosis factorαin J774.1 cells co-cultured with adipose mesenchymal stem cells co-cultured. METHODS:Adipose mesenchymal stem cells at a density of 2×107 per wel were inoculated into the upper chamber of the transwel and 24-wel plates. Then, J774.1 cells were suspended with cellculture medium containing 1 mg/L lipopolysaccharide and planted into the lower chamber of the transwel and 24-wel plates containing adipose mesenchymal stem cells as co-culture group. Meanwhile, inactive J774.1 cells to lipopolysaccharide-activat J774.1 cells served as negative and positive control groups, respectively. After 48 hours, the J774.1 cells were col ected to extract the RNA samples. Then, mRNA expressions of interleukin-6 and tumor necrosis factorαwere measured by real-time quantitative PCR. RESULTS AND CONCLUSION:Compared with the positive control group, direct-contact co-culture of adipose mesenchymal stem cells and J774.1 cells significantly reduced expressions of interleukin-6 and tumor necrosis factorαin J774.1 cells, but non-contact co-culture only reduced interleukin-6 expression. These findings indicate that adipose mesenchymal stem cells can inhibit the immune response of J774.1 cells activated by lipopolysaccharide.

Objective To investigate the feasibility of reducing spine metal artifacts with metal artifacts reduction technique (WARP) at 3.0 T MRI.Methods This study included 15 cervical and 14 lumbar spine cases.The image quality of WARP sequences and conventional sequences were compared (5 score evaluation scale) as well as the signal to noise ratio (SNR) and contrast noise ratio (CNR) of the image artifacts.The scanning time was recorded.Paired-t test and Mann-Whitney test were used respectively to compare the SNR and CNR,and qualitative scoring between the two sequences.P＜0.05 was considered to indicate a significant difference.Results The image distortion and blur of the WARP sequences were obviously reduced as compared to the conventional sequences.The SNR and CNR of artifacts of the WARP sequences were lower than that of the conventional sequences (All P＜0.05).The image quality scores of WARP sequences in cervical and lumbar spines[4(3 to 5) and 4(3 to 5)] were higher than that of conventional sequences[3(2 to 4),3(2 to 4)](P＜0.05).The scanning time of cervical spines in WARP sequence(14 min 9 s) was increased by 64 s (8.2％),and the time of lumbar spines (13 min 41 s) decreased by 9 s (1.1％).Conclusion The WARP sequences at 3.0 T could effectively reduce the artifacts of metallic prosthesis in cervical and lumbar spine without prolonging the scanning time at 3.0 T MRI.

RNA interference (RNAi) is a newly developed technology. It is the different levels of gene silencing induced by specific degradation of targeted genes in vivo, and both exogenous and endogenous double-stranded RNAs could induce the specific degradation. RNAi has been applied in tumor therapy, viral infection, hepatitis B and many other diseases. siRNA is the effector molecule which induces the RNAi in vivo. But naked siRNA is easily degradated by RNases in vivo, and the half-life is short. Meanwhile, the transfection efficiency of the naked siRNA is comparatively low. So the naked siRNA needs the help of vectors to penetrate the cell membrane and take action. Viral vectors have the potential immunogenicity and mutagenicity in gene therapy. Therefore, non-viral vectors are drawing more and more attention. The latest development of the non-viral vectors is summarized in this review.

Objective To explore the difference of plasma pentraxin 3 (PTX3) levels in acute coronary syndrome (ACS) patients,and to evaluate the correlation between plasma PTX3 levels and ACS as well as hypersensitive C-reaction protein (hs-CRP), through detecting the plasma levels of PTX3 and serum levels of hs-CRP in ACS patients, stable angina pectoris (SAP) patients and normal controls. Methods According to coronary angiography results,78 subjects were divided into control group (n = 20), stable angina pectoris (SAP) group (n = 22), and acute coronary syndrome (ACS) group (n = 36). The plasma levels of PTX3 and serum hs-CRP as well as routine blood biochemical markers were detected on the second day after admission. SPSS10.0 was used for one-factor analysis of variance and Logistic regression analysis. Results The logarithm level of plasma PTX3 in ACS group was significantly higher than that of the other two groups (P <0.05). The difference between the SAP group and the control group was not statistically significant (P > 0.05). Logistic regression analysis revealed that the estimated value of the plasma PTX3 logarithm level was 2.32 (P < 0.05), that of the serum hs-CRP was 0.447 (P > 0.05). Conclusion The plasma PTX3 level in ACS group is significantly higher than that of the SAP group and the control group. The correlation between plasma FTX3 levels and the ACS is stronger than that of the serum hs-CRP levels.
