Objective To establish the mouse bone marrow-derived dendritic cells expressing FasL protein and explore the mechanism of inducing allogeneic mouse spleen T lymphocyte apoptosis. MethodsMouse myeloid DCs were cultured in selective medium zontaining essential cytokines for DC growth in vitro. The mouse DCs were transfected with liposome-mediated FasL gene. The levels of FasL mRNA before and after transfection were assayed by real-time quantitative PCR. The expression levels of FasL protein were assayed by flow cytometry(FCM)and Western blot. Non-transfected DC，empty plasmid transfected DC and FasL transfected DC were infused intravenouslY into allogeneic mouse. After 7 days, the apoptosis in spleen T lymphocytes was evaluated by TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling)method and FCM. ResultsCultured in vitro, the mature myeloid DCs from mouse could be obtained.The expressions of FasL mRNA and protein in FasL transfected DCs were significantly higher. Through the detection of spleen T lymphocyte apoptosis with TUNEL，the apoptosis index(AI)was higher in FasL transfected DC(11.67±1.53)，compared with non-transfected DC(2.67±0.58)and empty plasmid transfected DC(3.33±0.58)，P＜0.01. ConclusionA large quantity of myeloid DCs can be obtained through in vitro culture in selective medium. The liposome-mediated FasL gene transfected DCs could successfully express high levels of FasL protein. Intravenous infusion of FasL gene transfected DCs could induce apoptosis of allogeneic mouse spleen T lymphocytes.

Objective To study the influence of different routes of keyhole limpet hemocyanin ( KLH) immuniza-tion on the T-cell-dependent antibody response in mice.Methods SPF Kunming mice were divided into four groups: the intravenous injection group, subcutaneous injection group, intraperitoneal injection group and control group.Each mouse was injected 200 μg KLH intravenously, subcutaneously or intraperitoneally daily for consecutive 10 days, respectively. Mice in the control group were given solvent injection only.Serum concentration of IgG stimulated by KLH antigen was measured 7 days after the last dosing.Spleen was isolated to calculate the organ coefficient and examined by pathology u-sing hematoxylin and eosin staining.Results Intravenously, subcutaneously and intraperitoneally administered KLH stimu-lated the generation of secondary lymphoid follicles and germinal center to varying degrees, B cell apoptosis, increased a-mount of cells in the marginal zone and other pathological changes were observed in the spleen.Intravenous and intraperito-neal administration of KLH led to more pronounced pathological changes compared with that in the subcutaneous injection group.All of the three administration routes of KLH induced generation of IgG antibody, significantly higher than that in the control group (P<0.05).Intravenous injection of KLH generated the highest concentration of IgG and organ coefficient among the three administration routes ( P<0.05) .Conclusions Different immunization routes do affect the production of IgG antibody, organ coefficient and pathological changes in the spleen, and these differences should be taken into consider-ation when analyzing the T cell dependent antibody response in mice.

Objective To investigate the inhibitory effects of cationic polymeric liposomes (CPLs) vector-based RNA interference (RNAi) technology on the expression of rat MHCⅡ transactivator ( CⅡTA) and MHCⅡgenes .Methods According to the genetic information of CⅡTA downloaded from GenBank, three short hairpin RNA (shRNA) sequences targeting CⅡTA sequences were designed .CPLs vectors were constructed and coupled to shRNA plasmid vectors to form pCⅡTA-CPLs vectors .Six groups including control group , CPLs control group , pHK-CⅡTA control group and three pCⅡTA-CPLs groups were set up.Rat dendritic cells (DCs) were transfected in vitro.Real time PCR and flow cytometry analysis were used to detect the expression of CⅡTA and MHCⅡat mRNA and protein levels in DCs after transfec-tion.Results The pCⅡTA-CPLs vectors were successfully constructed .Compared with control groups ,the transcription level of CⅡTA and MHCⅡand the expression of MHCⅡat protein level were significantly in-hibited in all pCⅡ TA-CPLs groups ( P<0 .01 ) .The strongest inhibitory effects of pCⅡTA-CPLs on the ex-pression of CⅡTA and MHCⅡgenes were observed in the second pCⅡTA-CPLs group.There was a positive correlation between the expression of CⅡTA and MHCⅡ.Conclusion CPLs vectors were effective gene carriers.The constructed pCⅡTA-CPLs vectors significantly inhibited the in vitro expression of rat CⅡTA and MHCⅡ, which provided evidences for further investigation on pCPLs-CⅡTA vectors in vivo.

Objective To investigate MRI signal features and MRI appearances of patients with advanced stage in polyacrylamide hydrophilic gel injection for facial plasty.Methods In this study,MRI of 11 cases with 23 polyacrylamide hydrophilic gel injection of facial plasty for 6 to 10 years were retrospectively reviewed.All images were acquired with GE 3.0T MR imaging unit.MR sequences,including FSE T1WI,FSE FS T2WI,and STIR were applied with 8-channel brain coil.MRIs sliced through the maxillofacial region in the transverse,coronal and sagittal planes.Results In 11 cases of 23 polyacrylamide hydrophilic gel injection,there were different degrees of capsule rupture and induration in 6 polyacrylamide hydrophilic gel injection,and the images showed sporadic callosities such as subcutaneous nodules and nodules in glands or muscles ; hydrogel migration in 8 polyacrylamide hydrophilic gel injection.Secondary deformity occured in 80 ％ cases,in which the most cases were induced by hydrogel migration.Conclusions Magnetic resonance imaging can make clear of the type of rupture and the distribution leakage of polyacrylamide hydrophilic gel for facial plasty and it is an ideal approach for advanced patients with polyacrylamide hydrophilic gel injection for follow-up.

Objective To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. Methods Published articles from the earliest date available to July, 2016 were recalled from PubMed, OVID, Embase, Co-chrane Library, CNKI, VIP and Wanfang Database. Two reviewers selected independently the randomized controlled trials (RCTs) about rT-MS for stroke patients with unilateral spatial neglect, and extracted data independently and analyzed with RevMan 5.3 and GRADE profiler 3.6. Results Twelve trials that represented 353 participants were evaluated. For improving Line Bisection Test, Star Cancellation Test, Albert Test, rTMS groups were significantly more effective than the controls. rTMS groups with different frequencies all showed significantly effec-tive:for low frequency rTMS, SMD=-1.21, 95%CI=-2.17 to-0.25;for high frequency rTMS, SMD=-2.56, 95%CI=-3.54 to-1.58;for continuous theta burst stimulation (cTBS), SMD=-2.51, 95%CI=-3.66 to-1.36. Conclusion rTMS is effective on unilateral spatial neglec-tin in stroke patients.
