Objective To investigate the signal transduction pathway of arachidonic acid(AA) and prostaglandin E-2(PGE-2) synthesis in macrophage invaded by Toxoplasma gondii. Methods Synthesis of AA and PGE-2, expression of COX_2 mRNA and protein following stimulation infection by Toxoplasma gondii were evaluated in RAW264^7 cells by ELISA, RT_PCR and Western blotting after treatment with calcium channel blocker verapamil, chelator of extracellular calcium EGTA and inhibitor of CaM trifluoperazine (TFP), selective PKC inhibitor H7. Results Production of AA and PGE-2 induced by tachyzoite was significantly inhibited by EGTA, TFP and BAPTA/AM, and the PGE-2 production was inhibited by H7, with a reduced expression of COX_2 mRNA and protein in a dose_dependent manner. Conclusion The parasite down_regulates macrophage functions by affecting PKC signaling pathways, and triggers a biochemical cascade whose signals ultimately conduct to the secretion of immunosuppressive molecules PGE-2.

Aim To explore the effects of inhibitors of glycosphingolipid biosynthesis D-PDMP on the proliferation and differentiation of neural stem cells. Methods Neural stem cells cultured in vitro were treated with different concentration of D-PDMP. The effects of D-PDMP on proliferation and differentiation of neural stem cells were evaluated by counting of neurospheres size and cellular number, MTT assaying and the experiment of inducing differentiation.Results Neurospheres were smaller in size after treated with D-PDMP. The data of cellular counting and MTT assay suggested that D-PDMP could inhibit proliferation of neural stem cells and lead cells death in higher concentration, D-PDMP also reduced the differentiation ability of neural stem cells. Although differentiated cells were fewer, they could be induced into neurons and astrocytes.Conclusion The inhibitors of glycosphingolipid biosynthesis D-PDMP could inhibit the proliferation of neural stem cells, even lead cells death. It also reduced the differentiation ability of neural stem cells.

Objective To investigate associations of UC with the polymorphisms of TRAIL receptors.Methods From January 2008 to December 2012, 380 consecutive UC patients [215 males and 165 females, the average age was (42.63 ±14.61) years] as well as 539 sex-and age-matched healthy individuals [290 males and 249 females, the average age was (41.29 ±15.86) years] were recruited from four large scale comprehensive hospitals in Wenzhou city.Five single nucleotide polymorphisms of DR4 (rs20575, rs13278062), DR5(rs1047266), DcR2(rs1133782) and OPG (rs3102735) were detected by a SNaPshot technique.Distributions of mutant alleles and genotypes for targeted polymorphisms in TRAIL receptors were analyzed by Chi-square test or Fisher′s exact test. By means of unconditional Logistic regression analysis, it evaluated associations between the polymorphisms and the risk of UC attack as well as the clinical features of UC patients.Furthermore, an unconditional Logistic multiple regression analysis was employed to investigate the independent risk factors of UC and their multiplicative interaction effects on UC.Results The frequencies of mutant allele (G) and genotype (CG+GG) of DR4(rs20575) were higher in UC patients than those in the controls (3.55%vs 1.95%,χ2 =4.512, P=0.034;6.58%vs 3.71%,χ2=3.938, P=0.047, respectively).However, the frequeucies of mutant allele ( A) and genotype ( GA+AA) of DcR2(rs1133782) were decreased in UC patients compared to the controls(6.18%vs 9.09%,χ2=5.183, P=0.023; 11.32% vs 17.44%, χ2 =6.589, P=0.010, respectively).The frequencies of mutant allele (T) and homozygote (TT) of OPG(rs3102735) were significantly higher in UC patients than in the controls (86.32% vs 81.54%, χ2 =7.385, P=0.007;75.26% vs 66.98%, χ2 =7.346, P=0.007, respectively) .Furthermore, the genotype (GG) of DcR2 (rs1133782) was found to be the independent risk factor for UC attack (OR=4.937, 95%CI:2.320-10.504, P<0.001).Moreover, the (GG) of DcR2(rs1133782) and (CC) of DR4(rs20575) had an interactive effect on UC (OR=0.322, 95%CI:0.164-0.633, P=0.001).The same conclusion was drawn for the ( GG) of DR4( rs20575) and (TT) of OPG(rs3102735) (OR=1.580, 95%CI:1.165-2.144, P=0.003).Conclusions The genetic polymorphisms of DR4 ( rs20575 ) , DcR2 ( rs1133782 ) and OPG ( rs3102735 ) were associated with UC. The mutation of DcR2(rs1133782) might play a protective role in UC.Moreover, the DcR2(rs1133782) and DR4(rs20575) gene had a collaborative effect on UC.So did the DR4(rs20575) and OPG(rs3102735) genes.

Healthy male subjects were asked to hold their breath in air at the tidal inspiratory level, and time-dependent changes in mean values of several parameters of cardiovascular function were studied. The heart rate increased abruptly after the beginning of breath-holding and then decreased slightly with time. The stroke volume (SV) remained significantly low until the end of breath-holding, so that the cardiac output was decreased in parallel. With regard to the systolic time interval, the totai eiectromechanical systole and the left-ventricular systolic time (LVET) were not significantly changed, whereas the pre-ejection period (PEP) was markedly prolonged. Therefore, ratios of PEP/LVET and SV/LVET were increased and decreased with time, respectively. As the systolic, and in particular the diastolic blood pressures were elevated, the pulse pressure was reduced. Ratios of the diastolic and systolic times in relation to the heart rate at rest, during breath-holding and during recovery after breath-holding were all proved to be described by a single regression curve. However, the ratios obtained for cycling exercise at various heart rates showed a marked shift above the curve. These results clearly indicate that cardiac performance is lowered during breath-holding in air.

ObjectiveTo investigate the dynamic changes of T helper (Th) responses and hepatic granuloma development during Schistosoma japonicum infection and to evaluate the possible correlation between the Th1/Th2 cytokines and pathological liver damage. MethodsSera from both Schistosoma japonicum infected C57BL/6 mice and uninfected controls were measured for interferongamma (IFN-γ), interleukin (IL)-4 and IL-13 at week 4, 6, 8 and 12 post-infection. At the same time, the splenic Th1/Th2 ratio was examined. The development of liver granulomas in infected mice was also observed and the correlation between the cytokines and granulomas were assessed. Wilcoxon test and Spearman rank correlation test were performed for data analysis. ResultsSerum IFN-γ level in infected mice was (2. 835±0. 049) lgpg/mL at week 4 post infection, which was significantly higher than that in controls [(1. 787 ± 0. 174) lgpg/mL, Z= - 2. 646, P = 0. 008]. Thereafter, the level declined after week 6, but remained higher than controls at the end of 12-week experiment (Z= -2.457, P=0. 014). IL-4 and IL-13 levels did not increase until week 6 (Z=-2. 646,P=0. 008;Z=-2. 646,P=0. 008), and peaked at week 8. After soluble egg antigen (SEA) stimulation, splenic Th1/Th2 ratio in infected mice was 0.5 (95％ CI 0. 2-1.2) at week 8 and 0.3 (95％ CI 0. 3-0.6)at week 12 post infection, both of which were significantly lower than those in uninfected controls (week 8: Z=2. 173, P=0.030; week 12:Z=2.551, P=0.011). Compared with unstimulated splenic cells, splenic Th1/Th2 ratio after SEA stimulation significantly decreased at week 8 (Z=2. 236, P=0. 025) and week 12 (Z=3. 130, P=0.002). Granulomas were first observed in livers at week 6 and the size kept on increasing. A negative correlation between serum IL-13 and the diameter of liver granulomas was discovered at week 12 post infection (r=0. 636, P= 0. 048). Conclusions Th1 response is dominant during the early stage of Schistosoma japonicum infection.However,followed by oviposition, Thl response declines and meanwhile a strong Th2 response gradually develops. Therefore, Th2 response probably plays a role in the development of hepatic granulomas.
