Dendritic cells are the key cells to regulate immunity. Tolerogenic dendritic cells (Tol-DC) with immunosuppressive function play an important role in inducing and maintaining immune tolerance. In recent years, a class of liver Tol-DC with low level of presenting antigen and inhibition of T cell activation and proliferation has become a research hotspot to reduce the rejection of liver transplantation. At the same time, there are many strategies to induce phenotypic stable Tol-DC, which lays a foundation for its clinical application. This article introduces the current understanding of liver Tol-DC and its mechanism of regulating the immunity of liver transplantation, in order to provide new ideas for immunotherapy of liver transplantation.

Objective:We clarify the relationship between dysfunction of gastric motility and the plasma motilin,in order to study the pathogenesis,diagnosis and therapy of the hepatocirrhosis with dyspepsia.Methods:The liquid gastric emptying (GE),electrogastrograpgy(EGG) and plasma motilin were examined in 51 patients with hepatocirrhosis.Results:The dysfunction of gastric motility is associated with the liver function,gastric rhythm and upper gastrointestinal symptom.The plasma motilin concentration increased significantly in patients with hepatocirrhosis as compared with that of controls (P<0.01).The sorbefacient prokinetic drug (prepulsid) can improve the function of gastric power,but the lever of motilin no change.Conclusion:The patients with hepatocirrhosis have the dysfunction of gastric motility,and gastric emptying delayed,and there is a relation between GE and the liver function.We evaluate that this disorder is associated with the low sensitivity about stomach to the plasma molitin in this case.We can judge the degree of the liver damage,gastric emptying delayed.gastric rhythm by testing the gastric motilin.Drug can deal it.

Objective To evaluate the effects of traditional Chinese medicine likeDansen and western medicine in treating traumatic brain edema (TBE). Methods A total of 130 Wistar rats were divided randomly into six groups: Group A (normal contrast group), Group B (operation group), Group C (western medicine treatment group, WM group), Group D (western medicine and salvia injection), Group E (western medicine and Honghua injection) and Group F (western medicine and Sanqi injection).

BACKGROUND: The relationship between liver cancer recurrence and hepatitis B virus recurrence remains poorly understood and it is considered to be related to application of immunosuppressive agent after liver transplantation. OBJECTIVE: To investigate the effects of tacrolimus (FK506) on the proliferation of HepG2.2.15 cells and the replication of hepatitis B virus in vitro. METHODS: HepG2.2.15 cells were in vitro cultured. After passage 3 HepG2.2.15 cells were cultured for 24 hours, they were interfered with different concentrations of FK506. 0 g/L FK506-interfered group served as control group, 50 g/L FK506-interfered group as low-concentration FK506 group, 100 g/L or 500 g/L FK506-interfered group as medium-concentration FK506 group, and 1 000 g/L or 3 000 g/L FK506-interfered group as high-concentration FK506 group. RESULTS AND CONCLUSION: Moderate- and high-concentration FK506 exhibited inhibitory effects on the proliferation of HepG2.2.15 cells, while low-concentration FK506 exhibited no inhibitory effects with correlation. High-concentration FK506 made HepG2.2.15 cells arresting at G0/G1 stage. FK506 decreased CyclinA expression in HepG2.2.15 cells in a dose-dependent manner. Higher concentration of FK506 leaded to lower expression of CyclinA. FK506 did not produce effects on the replication of hepatitis B virus in HepG2.2.15 cells. These results indicate that FK506 inhibits the proliferation of HepG2.2.15 cells in vitro, which occurs possibly due to Cyclin A, but it would not affect the replication of hepatitis B virus in vitro.

Objective To investigate the molecular mechanism of vascular endothelial growth factor ( VEGF) expression in bronchial epithelial cells (Beas-2B)induced by particulate matter 2.5(PM2.5).Methods PM2.5 powder was dis-solved in DMEM medium and diluted into five concentrations , 0,12.5,25,50 and 100μg/ml, respectively.The double an-tibiotics ( streptomycin and penicillin ) and FBS were added into the solution to a 2% final concentration of serum system after being treated by ultrasound for 30 minutes.The cultured Beas-2B cells were then treated with different doses of PM2.5.Subsequently, nuclear factor-kappa B(NF-κB) transactivity and the transcriptional activation of vegf gene promot-er were tested by dual-luciferase reporter gene analysis system while phosphorylation of p 65 , expression levels of IκBαand VEGF were detected by Western blotting .Results PM2.5 induced up-regulation of VEGF expression in Beas-2B cells in a dose-dependent manner , accompanied by NF-κB transactivation at the highest level under 100 μg/ml of PM2.5 treatment. Moreover, PM2.5 induced degradation of the repressor protein IκBαand increase in the phosphorylation level of p 65 sub-unit in Beas-2B cells.Knockdown of NF-κB p65 expression significantly inhibited vegf gene promoter transcriptional activa-tion as well as VEGF protein expression in Beas-2B cells induced by PM2.5.Conclusion PM2.5 induces VEGF expres-sion via activation of NF-κB pathway in bronchial epithelial cells .

Objective To explore the signal transduction mechanism of inhibitor kappa B kinase α( IKKα) , one of the catalytic subunits of IKK complex , for regulating p53 transactivation in the cellular ultraviolet radiation ( UVB) repsonse. Methods The transactivation of p53 was determined by dual-luciferase reporter gene analysis system while the expression and activation of IKKα, IKKβ, p53 and p38K was detected by Western blotting assay .Results UVB exposure induced activation and transactivation of p 53 in the wild type mouse fibroblasts ,but the effect was blocked by IKKa deficiency and recovered by reconstitution of IKKαexpression.Under the same conditions , IKKαregulated p38K activation, while inhibi-ting p38K activation down-regulated p53 transactivation under UVB exposure .Conclusion IKKαregulates UVB-induced phosphorylation and activation of p 53 in a p38K-dependent manner .

Objective To investigate the immunomodulatory effects of heme oxygenase-1 ( HO-1) modified rat bone marrow mesenchymal stem cells ( BM-MSCs) on lymphocytes .Methods Rat BM-MSCs were cultured and identified in vitro.HO-1 gene was transduced into BM-MSCs via recombinant adenovirus (rAdV) to construct HO-1/BM MSCs, which were then co-cultured with rat spleen lymphocytes .The cellu-lar activity of lymphocytes was detected by using MTT method .The cell cycle distributions were analyzed by propidium iodide staining and flow cytometry .ELISA was used to detect the level of cytokines in the super-natant of cultured cells .The expression of lymphocyte activation markers , CD25 and CD71, were measured by using fluorescence labeled antibodies and flow cytometry .Results Compared with the control group , the lymphocytes co-cultured with HO-1/BM MSCs showed a suppressed proliferation and cell cycle progression . HO-1/BM MSCs inhibited the secretion of IL-2, TNF-αand IFN-γ, but enhanced the secretion of IL-10 in lymphocytes.Furthermore, the expression of CD25 and CD71 were also down-regulated by HO-1/BM MSCs. Conclusion Compared with BM MSCs , HO-1/BM MSCs show higher immunosuppressive effects on lym-phocytes .
