Objective To detect the expression of type Ⅰ interferon in monocyte-derived dendritic cells(MoDCs)after Toll like receptor(TLR)3 triggered in patients with chronic hepatitis B(CHB),and to evaluate immune responses of CHB patients and its roles in the mechanisms of persistent infection of hepatitis B virus(HBV)and chronicity of hepatitis.Methods Peripheral blood mononuclear cells(PBMCs)were isolated and purified using magnetic beads(plasma was saved simultaneously)from 26 CHB patients and 18 healthy volunteers(HV).Dendritic cells(DCs)were induced and proliferated in a culture medium with recombinant human granulocyte macrophage colony stimulating factor(rhGM-CSF)and recombinant human interleukin(rhIL-4).EX3s were stimulated with Poly Ⅰ:C and the supernatants were collected at 0 h and 24 h after stimulation.Type Ⅰ interferon(IFN-α and IFN-β)in plasma and supernatants were examined by enzyme linked immunosorbent assay (ELISA).Results The levels of type Ⅰ interferon in plasma were not significantly different in groups of HV and CH B.IFN-α and IFN-β expressions in supernatants before Poly Ⅰ:C stimulation were(80.00±16.15)ng/L,(36.39±13.90)ng/L in CHB group and(76.76±15.90)ng/L,(37.14±13.68)ng/L in HV group,respectively.And there were no statistical differences between two groups(t=1.651,t=0.178;both P＞0.05).IFN-α expressions in supernatants at 24 h after stimulation in two groups were both higher than those before stimulation(at 0 h),but there were no statistical differences(t=1.534,t=1.243;both P＞0.05).IFN-β expressions in supernatants at 24 h after stimulation in HV group was(54.57±16.80)ng/L,which was significantly higher than that at 0 h(37.14±13.68)ng/L(t=4.061,P＜0.05).However,there was no significant difference at 24 h than tht at 0 h in CHB group(t=1.796,P＞0.05).At 24 h after stimulation.IFN-β level was(54.57±16.80)ng/L in HV group,which was significantly higher than that[(41.64±12.57)ng/L]in CHB group(t=2.921,P＜0.05).Conclusions Functions of MoDCs from CHB patients are impaired and MoDCs could not express type Ⅰ interferon normally.Expression of type Ⅰ interferon after TLR3 triggered in CHB patients is mainly IFN-β.

Objective To elucidate the expression of Toll-like receptor 3 (TLR3) on dendritic cells(DCs) in patients with chronic hepatitis B (CHB), and to explore the correlation between hepatitis B virus (HBV) persistent infection and TLR3 expression. Methods Sixty CHB patients (CHB group) and 20 healthy controls (control group) were enrolled. The peripheral blood mononuclear cells (PBMCs) were isolated and CD14~+ monocytes were sorted by immunomagnetic beads. Immature DCs (imDC) were induced and proliferated in vitro and mature DCs (mDC) were obtained after the poly I:C stimulation. The expression of intracellular TLR3 mRNA was detected by real-time polymerase chain reaction (PCR), and surface markers [CD80 and human leucocyte antigen (HLA)-DR] were determined by flow cytometry after 48 h of stimulation. The comparison of quantitative data was done using t test. The qualitative data were compared using chi-square test.Results The mean fluorescence intensities (MFI) of intracellular TLR3 of imDC before poly I:C stimulation in CHB group and control group were 1212.05 ± 250.80 and 1192.95 ± 301.40,respectively, which were not significantly different (t = 0. 280, P>0. 05). While after stimulation,those were 1352.98± 313.67 and 1593. 00± 349. 65, respectively, the latter was significantly higher than the former (t = 2. 880, P<0. 05). The levels of TLR3 mRNA inside mDCs in both groups were increased after poly I:C stimulation, which were 0. 1204 ±0.0267 and 0. 1780 ± 0.0664, respectively in CHB group and control group, and that in control group was significantly higher (t = 3. 909, P<0.05). Furtherly, patients in CHB group were divided into HBeAg(+ ) and HBeAg( -) subgroups.After stimulation, the MFI and mRNA of TLR3 inside mDC were greatly elevated in both subgroups,but there were no difference between these two subgroups (t = 0. 366, P>0. 05). Conclusions The intracellular expressions of TLR3 in mDC in CHB group and control group are obviously increased after the poly I:C stimulation, but the increased level in CHB group is lower than that in control group. The results suggest that the insufficiency of TLR3 synthesis may be related to the HBVpersistent infection.

Objective To investigate the inlfuence of overexpression of miR-26b on the secretion of adipokines dur-ing human adipocyte differentiation. Methods Human preadipocytes were infected with the hsa-miR-26b over-expressing lentivirus and were induced to differentiate, and then the levels of adipokines (IL-6, leptin, resistin, TNF-α) at different time points during differentiation were measured by ELISA. Results Compared with control group, decreased secretions of both IL-6 and leptin, and increased secretion of resistin were found during the differentiation of human adipocytes in miR-26b overexpressed group. However, the secretion of TNF-αwas not measured in both groups. Conclusion The miR-26b can improve the inlfammation and insulin resistance of human adipocytes, which will provide potential targets for obesity treat-ment.

Objective To summarize the diagnostic efficacy of ADC value for differentiation of benign and malignant lymph nodes on diffusion MRI with Meta-analysis. Methods Published papers on differentiation of benign and malignant lymph nodes with ADC value were searched and reviewed.Quality evaluation was performed for the eligible papers before data extraction.Test for heterogeneity was performed first,then appropriate model was selected to calculate the weighted mean difference,sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,diagnostic odds ratio,pretest and posttest probability.The potential of ADC value for differentiation of benign and malignant lymph nodes was assessed qualitatively and quantitatively.Results Fifteen papers including 735 cases and 1963 lymph nodes were selected.According to Meta-regression analysis,subgroup analysis and robust analysis,two studies with benign lymph nodes in patients with benign lesion and one study using chemical shift saturation technique were excluded because of their impact on the robustness of the pooled results. The weighted mean difference (WMD) between malignant and benign lymph nodes was -0.355 × 10-3mm2/s[95％ confidence interval (CI):-0.423 ×10-3- -0.288 × 10-3 mm2/s].Although the cutoff of ADC value for differentiation in each study was different,the diagnostic efficacy was stable,the pooled sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,diagnostic odds ratio and area under summarized receiver operator's curve were 0.87 (95％ CI:0.79-0.92),0.87 (95％ CI:0.82-0.90),6.5 (95％ CI:4.7-9.2),0.15 (95％ CI:0.09-0.25 ),43 ( 95％ CI:21-87 ),0.93 ( 95 ％ CI:0.90-0.95 ).The posttest malignancy probability of benign lymph node indicated by ADC was 6％,while that of malignant lymph node was 72％.Conclusion The ADC value can be used to differentiate benign and malignant lymph nodes with good sensitivity and specificity noninvasively.

Action potential amplitude of experimental ischiadic nerves far from heart in 2-week group,2-month group and 4-month group were (11.18±3.38), (11.68±3.21), ( 12.52±3.09) mV, while that of the control sides were (11.56±4.80), (10.71±3.40), (11.67±2.48) mV ,there was no statistical significance in the same group respectively(t=0.29,1.01,0.55, P>0.05 ). Nerve conduction velocity of experimental ischiadic nerves in 2-week group,2-month group and 4-month group were (40.56± 9.46), (38.79±5.78), (39.44±8.64) m/V, the control sides were (42.56±6.59), (44.64±7.53), (43.33±6.05)m/V, there was no statistical significance in the same group respectively( t = 0.57,1.94, 0.01,P>0.05). There were some changes in general observation and light microscope, in electron microscope, many non-specificity changes were observed. All of these changes included delamination, collapse, disaggregation of the myelinated nerve, mitochondria swelling and vacuolization of neurilemma cell and axon. The ratio of degenerative alterations in nerves was 60% --70% in 2-week group, 50% in 2-month group and 30% in 4-month group, and there was statistical significance among three groups (P<0.05). Conclusion 125I permanent plantation in our test dose has little effect on ischiadic nerve, all these non-specificity changes were observed in electron microscope, and it has no evident impacts on physiological functions.
